Living on an island might sound wonderful． But what if you left for a trip and found you could never return？ What if your home， and even the land it stood on， was gone forever？For people living in the Pacific Islands，this is really possible．
Why？ Climate（气候） change． Climate change is causing the sea to rise． That's bad news for the Pacific Islands． Young people on the islands are even starting to wonder：Will they be the last generation（一代人）？
Not if the islanders have anything to do about it．These people are deeply connected to their homelands． The Pacific Islands are made up of 11 different countries： the Marshall Islands， Fiji， Samoa，and others． But now， those countries are working together． They're joining forces to fight climate change．
Why is climate change such a huge threat to this part of the world？Islands have low elevations（海拔）．So they are among the first places influenced by rising sea levels． That's why countries of the Pacific Islands are working together to do their part．
But these are small countries． When it comes to climate change， can they make a big difference？ They can， because most of the things that people on islands buy are brought by ships．This is very harmful to the environment． After all， ships put out almost 3 percent of the world's carbon emissions（碳排放）．That makes climate change worse．
Pacific Islanders realize the problem． So， in 2019，six countries got together：Fiji，the Marshall Islands， Samoa，Vanuatu， the Solomon Islands， and Tuvalu． They came up with a plan． They agreed to cut carbon emissions from shipping by 40 percent by 2030．And by 2050，they expect zero﹣carbon shipping．
How will they pull this off？ They plan to use some really cool carbon﹣free technologies．They'll make use of solar and wind energy．
Sea levels are rising， but hopes aren't sinking in the Pacific Islands．
（1）What is the bad news for the Pacific Islands according to the passage？
A． Some Pacific Island countries have disappeared．
B． The sea level is going up because of climate change．
C． All the sipping to the Pacific Islands has been stopped．
D． The Pacific Islands have nothing to do about the climate change．
（2）The underlined word "threat" in Paragraph 4 probably means" "．
A． risk
B． step
C． project
D． development
（3）It can be inferred from the passage that ．
A． there will never be zero carbon emissions from sipping
B． solar and wind energy will make climate change worse
C． all the Pacific Islanders may leave their homelands by 2050
D． some Pacific Island countries may have hopes to make a difference
（4）The passage mainly talks about ．
A． why other countries are helping the Pacific Islanders fight climate change
B． how some countries are working hard to develop carbon﹣free technologies
C． how Pacific Island countries are working together to fight shipping pollution
D． why Pacific Island countries put out so much of the world's carbon emissions
Imagine this． There's an apple and a piece of cake on a table． Which one would you like ？The delicious cake or the healthy apple？ A bestseller， Willpower Rediscovering Our Greater Strength ，suggests that willpower（意志力） is the ability to make decisions that are better for us in the long term， rather than in the short term．
Here is a famous experiment in the book：The Marshmallow Test．In 1972，Professor Walter Mischel tested the willpower of 600 four﹣year﹣olds to six﹣year﹣olds．In the experiment，each child was left alone in a room for fifteen minutes with a marshmallow（棉花软糖） on a table in front of them．They were given two choices： they could either eat it or，if they waited fifteen minutes，they'd be given a second one （and then they could eat both）．
So， what did the kids do？ Well， as you can imagine，70% ate the first marshmallow within the fifteen minutes．But the other 30% showed willpower they controlled themselves and waited for the second marshmallow．But then Mischel discovered something really interesting． Twenty years later， he got in touch with the children， who， by then，were in their early twenties．And he found that those who'd shown strong willpower were getting better marks at university and were more popular．
Willpower is like a muscle（肌肉），and the more you exercise it， the stronger it gets．So，if you do daily "self﹣control exercises"，such as making your bed or brushing your teeth，you'll improve your overall willpower． And daily willpower exercises will help you with those bigger goals， such as studying for an exam or training for a marathon．
Be careful though． Just like any muscle， your "willpower muscle" can get tired．If you've had to do lots of things that require willpower， take a break or give yourself a treat．
That way，you'll build up your willpower again．
And one last thing， the writer mentions people who learn foreign languages usually have a lot of willpower． So， congratulations!

Seven years ago，Joyce Akinpe moved to Australia to start a new life，finding an exciting job in Sydney．After the outbreak（爆发）of COVID﹣19，she suddenly lost her job．
Seeing that there were many others like herself in trouble from the outbreak，Akinpe and her two roommates， Michelle Gomez and Maureen Lee，brainstormed ideas for how to help their local community．They came up with a street pantry（储藏柜）．Gomez said the idea was very simple，"Take what you need and leave what you can．"
With the help of Gomez's father， they built the Blessing Box﹣a street pantry，with shelves and hanging baskets and two doors made from old furniture．
It sits just at the back of the three girls' home ，so they can look after it．They put some information notices into their neighbors' mailboxes，and the Blessing Box was quickly filled with the donations （捐赠）from the community．"It is the community's strong support that keeps the project alive，"Akinpe said．
"We now have hundreds of people visiting our box every day．It might only take two hours for the box to be full and next hour it might become empty again．We are now helping others to carry out similar projects in their own communities， too，"Gomez said．
Lee said things in the box were mostly convenience foods，as well as some necessary life things such as spaghetti and toilet paper．"Few people take everything at once．They think there are other people who need them more．"Lee added．

With schools closed and restrictions（限制） on public activities it can be as time with their friends difficult time for young people who suddenly can't spend and family in person．
However ，the situation has already to some creative ways of using technology to keep in touch with those people， from video calls and group chats（聊天） to online games． Experts say that young people might find the social restrictions on seeing their friends in real life stressful， which is why technology can be helpful，
"Keeping relationships is very important for health，" says Dr Amanda Gummer． creator of Dr Gumer's Good Pliy Cuide．She adds that this is more important the older you get． "Not maintaining these friendships can make it more difficult for you to get back into school when the time comes，" she says．Chezzy Kennedy， from a raining program called Confident Kids， agrees． "Staying connected to those we care about is even more important now than ever before，" she says．"We can suddenly feel quite lonely．"
Messaging apps and video calls are good for checking in with friends， or organizing group chats to keep in touch．"Video chats are a great way to keep connected with your wider friendship group，" says Gummer． Experts agree that there are plenty of ways to be creative with video chats besides talking to friends．Gummer suggests，"A virtual（虚拟的） film and pizza night can work well． "
Sharna Jackson， an expert on young people and technology， has lots of ideas too．She suggests taking turns to teach friends something you're really good at﹣such as painting and drawing， perhaps． She also thinks that online games， including Fortnite and Minecraft， can play a really good role．

On February 12， 2019， Brendon Fontaine blew out five candles on a birthday cake． "He loved the cake so much，" says his mother， Faith， who lives in Winnipeg with Brendon． "I had to hide it in the back of the fridge．
Brendon's surprise came from Cakes for Kids， a group of home bakers（烘焙师） who know that a simple birthday cake can be uncommon for poor families like the Fontaines．
The group was set up three years ago by Christy Rogowski， a 40﹣year﹣old who works in health care was really upsetting，" Rogowski says．
A Facebook call out for volunteers finally added 150 bakers to their name list．' When volunteers first apply （申请），they're asked why they want to do so．"Some people have said that they didn't have a cake on their birthday growing up，and they know how important it is，" says Singleton． More commonly， though， they say they want families in need to know that their neighbors care about them．
The names of the cake receivers are provided by community organizations and Winnipeg Child and Family Services． A child might receive a cake because the family is poor． Sometimes a child is sick， leaving the family too busy to make the treat themselves． Cakes also go to children living in foster care （寄养）．Jodi Korolyk， a worker with Winnipeg Child and Family Services， has so far ordered birthday cakes for five of the almost 800 kids in their system．"It shows the child they have a lot of people there to support them，" she say．
By the end of last year， Cakes for Kids had baked over 575 cakes to mark kids' birthdays， and the baking continues． Rogowski and Singleton are even considering developing the program nationally and also providing cakes for old people who live alone． After all， there's no age difference when it comes to the positive role of a well﹣ timed cake．

A Chinese song could be heard in a classroom in Sanaa， the capital of Yemen（也门），where around 20 Chinese learning schoolchildren were singing．
"I love to learn the Chinese language because it is very nice，important and I want to travel to China to complete my studies there，" Karim al﹣ Areqi， a student of the private Languages Model School in Sanaa， told Xinhua．
Teacher Mohammed al﹣Ansi， who learnt the language in China and received a university degree， stressed（强调） the importance of learning the Chinese language．" It is the language of the future and it is necessary for all people to get advantages from the great development in China，" he said．
Like many other private elementary and secondary schools in Yemen， the Chinese language is a basic part of the Languages Model School's courses， where the students study Chinese as actively as math and science subjects． "In teaching the Chinese language， I succeeded in educating students in a simple way that fits everyone，" al﹣Ansi said proudly， stressing that teaching Chinese has changed his life without doubt．
A﹣Ansi expects that Yemen and China will work together to set up centers and schools for teaching the Chinese language in Yemen so that many young Yemenis can learn． "I hope that a branch of the Confucius Institute（孔子学院） could be built in Yemen to teach the language and spread the Chinese culture to many students and researchers who are interested in learning the Chinese culture and language，" he said．

On a June afternoon in 1752， the sky began to get dark over the city． As the storm broke， most people surely hurried inside， but not Benjamin． Franklin． He decided it was the perfect time to fly a kite． Franklin had been waiting for a chance like this． He wanted to show the connection between lightning（闪电） and electricity，and to do so， he needed a storm．
He walked into field， and flew a kite with a piece of rope tied to it． A key was tied to the rope． The lightning hit the kite， and electricity passed through the rope to the key． Franklin then touched the key with his finger and got an electric shock（电击）． This， he said， proved（证明） the electrical nature of lightning．
For many years， schools have taught the story of Franklin's experiment． Millions of schoolchildren have been amazed by his courage and his scientific spirit of looking for the truth． However， new research suggests that the story may be fiction instead of fact． Although Franklin's experiment took place， more than one scientist has questioned what really happened．It's true that he did the experiment with the rope and the key． But scientists all agree that if Franklin had actually touched the key， he would certainly have died from the electric shock．
Scientists often question accepted ideas because they want to find out the facts． Some have even questioned the story about the apple that fell on Newton's head． Many reports suggest that although the falling apple certainly provided ideas，there is nothing to show that the apple actually hit him on the head，
In fact， fiction is often more interesting than the truth．People have been more encouraged by Franklin's spirit than by the facts themselves． But in science， facts should be tested by experiments and research， and we should not always believe everything we read or hear even if it is a great story．
（1）Franklin did the experiment in order to prove ．
A． he was an excellent scientist
B． flying a kite in the storm was safe
C． he was not afraid of lightning
D． lightning was a form of electricity
（2）The underlined word "fiction" probably means something ．
A． not true
B． quite different
C． not safe
D． quite necessary
（3）Some scientists questioned whether Franklin in the experiment．
A． flew a kite
B． touched the key
C． was present
D． discovered electricity
（4）The purpose of the passage is to tell us ．
A． Franklin's spirit is encouraging
B． fiction is more interesting than the truth
C． Franklin's experiment is not real
D． we shouldn't always believe accepted ideas
My father， who was always drunk and angry， beat me more and more every day． He always locked the door when he went away and kept the key in this pocket． One day I found an old saw（锯子） that he hid in the roof． When I was alone in the house，I started to make a hole on the floor under the big table．
The next day my father said，"Huck， go to the river and catch some fish for breakfast． Quickly! And don't try anything． Remember， I'm watching you!"
While I was fishing by the river， I saw an empty boat nearby．
"A boat!" I thought happily，"This is my chance to escape． I'll hide the boat near some trees and use it tonight!"
When my father went to town that afternoon， I got my saw and started to work on the hole． It was late afternoon when I finished making the hole．
"I did a good job，"I thought， looking at the hole． "Now I'll get my father's gun．
I looked outside the window and there was nobody there． I quickly escaped through the hole． Then I ran into the woods to hunt a wild pig． Luckily， I found one． I shot it and took it back to the house and let the pig's blood fall on the wooden floor of the house． Then I pulled some of my hair out and put it on my father's axe（斧子） with some of the pig's blood． I took the pig's body outside and put it in a big bag with some rocks， and threw it into the river．
"This way people will think__▲__ !"I thought． "They'll come and look for my body in the river．"This idea made me smile．
I waited until it was dark and got into the boat and went to Jackson's Island． I knew about Jackson's Island because Tom， Ben， Joe and I had a lot of fun adventures there．

Long long ago， there lived a man and a woman who had seven sons． The couple wanted a daughter， very much， and finally， they had a girl． She was very pretty and her parents loved her very much． One day the father needed water for the child， so he sent the seven brothers to a well（井） in the forest to get it． Once there， though， the boys began to fight and the water jug （壶） fell into the well． The boys looked into the well and thought of their father． They were afraid to go home．
Hours passed． "Where are those boys？" shouted the angry father．"They are probably playing a game and have forgotten about the water． I wish they were all turned into ravens （乌鸦） !" And when he looked up， he saw seven black birds flying away． The father was shocked．"What have I done？" he thought． But it was too late． He could not take back his words．
Later， the girl grew up and discovered she had brothers． The story of their bad luck influenced her deeply， and she decided to find them． For years， she searched and did not stop． She made up her mind to find them． Finally， she found their home．To enter，she needed a special key made from a chicken bone，which she did not have．The girl thought for a moment，and then took a knife and cut off one of her fingers． With it， she opened the front door and went inside． On a table， there were seven plates and seven cups． She ate and drank a little from each of them． In the last cup， she accidentally dropped a ring that her parents had given her．
Later that day， the ravens returned for their meal． The girl hid behind the door and watched． When the seventh raven drank from his cup， something hit his mouth． The raven recognized it at once﹣it was his parents' ring．"I wish our sister were here，" he said， "and then we could be free．" At that moment， their sister ran to them， and suddenly the ravens were human again．The brothers kissed their sister，and all eight of them went home together happily．

In the future， people may travel to Mars （火星） by water﹣powered spaceship! Today's spaceships are fine for getting things into space， but they are not so good at travelling long distances． These spaceships burn chemical fuels （燃料）， and they are very expensive． Scientists say that a water﹣powered spaceship could make the trip to Mars much cheaper． The idea is just in the planning stages now， but scientists think such a spaceship could be developed soon．
The key to the water﹣powered spaceship is the engine （发动机）． Regular engines push spaceships by burning fuel． The water engine will use steam， created by solar panels （太阳能板） that heat water to a high temperature． Of course， the spaceship will have to carry a lot of water for the long trip to Mars． Today's spaceships could not carry that much water．But scientists think that a spaceship blown up like a balloon will be able to．
One US company has already developed a spaceship like this． These spaceships are made of a strong material． Two of them have already been sent up into space， using rockets and then later filled with air．"Balloon" spaceships could be very large and carry enough water for a long trip． With the "Balloon" spaceships， enough water could be carried to power the engines and grow food during the trip． And the people on the spaceship might even get to take a hot bath!
Scientists say the biggest advantage of such a spaceship would be cost． The "Balloon" spaceship uses water to push it through space and costs about one thirtieth of a normal spaceship． Such savings naturally encourage continued research into balloon spaceships and w after engines． If these scientists are correct， we may soon be on our way to Mars in a spaceship powered by water．
（1）Which sentence best describes the main idea of the passage above？

Robots Are Now Teaching English!
Get ready． Robots are about to invade our classroom． From Korea to Japan to the United States， schools are putting English﹣speaking robots in front of their students． In Korea， robots are the new teaching assistants in a number of preschools and kindergartens． The young students say that the robots are fun， but are these children really learning anything？
I don't think a computer will ever be able to do what a teacher does． A teacher has to be able to respond to students as individuals （个体）．__▲__and a teacher has to change his or her teaching style to fit the needs of the student． I seriously doubt that a computer will ever be able to do this even though the big data （数据）is widely used in the world．
4 Comments on "Robots Are Now Teaching English!"
Sara says：
In my opinion， schools should spend money training human teachers rather than buying robots． Research shows that children learn more from real speakers than from recorded conversations．
Keiko says：
I don't think you can learn a language without real human interaction．After all， robots cannot think as humans do．
Hassan says：
Robots might be able to help people lean a language， but I don't think they should replace teachers because robots are just machines without human feelings．
Nancy says：
I think robots might be very helpful in the classroom． A child might be less afraid to make a mistake in front of a robot than in front of a real person．
