Many scientist once believed that physical similarities between identical twins are genetic（基因的），while their personalities，intelligence and other differences between them are an effect of their environment.Now scientists are discovering that the boundaries（界限）between genes and environment are not so clear.
Twins Jim Springer and Jim Lewis were adopted（领养）as babies and raised by different couples.When the Jims finally met at age 39，they discovered they had plenty in common.Both were six feet tall，180 pounds.They had the same smile and the same voice.When scientist Thomas Bouchard Jr.invited the Jim twins to his lab，people there found it very hard to tell them apart.
But the similarities didn't stop at the physical.They'd both had dogs named Toy.They had both married women named Linda and then their marriage broke up.They'd both been policemen，enjoyed music，and left love notes around the house for their wives.They had so much in common，it seemed unlikely these were just coincidences （巧合）.
The Jim twins were just one of 137 sets of separated twins.Bouchard tested.When they compared the twins' IQ scores，Bouchard and his team reached a surprising conclusion（结论）.They concluded that intelligence was mostly connected to genes rather than to training or education.It seemed the differences in family and environment had little effect.
However，genes can't control everything，argues geneticist Danielle Reed，who also studies twins.Reed's research shows that though nothing can truly change our DNA，environmental differences that a child experiences before birth and in their first year can sometimes affect the way the DNA behaves，making even identical twins into very different people. "What I like to say is that Mother Nature writes some things in pencil and some things in pen， "She explains. "Things written in pen you can't change.That's DNA.But things written in pencil you can. "

In the world there are a lot of people using public transport, some love it and still some dislike it. If everyone has a car and drives anywhere they want to go, there will be serious traffic problems on the road. Luckily, trains are a good form of public transport.
British people use trains a lot. This is especially so for people who are traveling from London to Paris. Every day about 20 trains leave London. They travel at a very high speed and people feel glad that the trains take only 2 hours and 30 minutes to reach Paris. It's much faster to travel by train than by bus or by car. This is because people have to drive cars or buses very carefully and lowly for many reasons, such as speed limits and trafficjams. However, when you are traveling by train, the speed is almost the same and there is no traffic jam for a train.
Besides, Londoners think taking a train is one of the safest ways of traveling on the ground. Trains take quite a number of quality tests while they are made. More importantly, they have to take many safety checks before they are used on the rail track.
What's more, trains in Britain are comfortable and provide fine services for their users. When you are on a London train, you will find that the train has comfortable tables and seats where people can sit. They also provide food services and power plugs(电源插头) for personal computers or mobile phone. The main idea of the passage is that ________.
| A．British people enjoy public transport |
| B．it's fast to travel from London to Paris |
| C．trains in Britain provide fine services for their users |
| D．trains are a good form of public transport for Londoners |
In a traffic jams on the road, ________.
| A．drivers can drive fast |
| B．drivers can drive carelessly |
| C．cars are not moving fast |
| D．cars will stop working |
The 3rd paragraph of the passage mainly talks about the ________ of trains.
| A．speed | B．safety | C．services | D．problems |
Londoners often travel by train because trains are ________.
| A．old and slow | B．large, clean and powerful |
| C．fine and important | D．fast, safe and comfortable |
What can we know from the passage?
| A．We can travel from London to Paris in less than 2hours. |
| B．We can do our work with personal computers on the train. |
| C．We have to wait till we get off the train in order to have some food. |
| D．The trains are only checked for quality reasons before they are used. |
A mind map is basically a tool that connects information around a central subject.It can help you make a knowledge bank to solve problems.A student recently said， "I thought mind mapping would take a lot of time to do but in fact it saves me time.（1）

Why does the chicken cross the road? To get to the other side!
That’s an old joke in the west, but it came to my mind again when I saw people crossing the road at the intersection of Shanxi Road and Huaihai Road in Shanghai.
When the traffic light was red, a group of people were waiting for the light to change. Suddenly one man began rushing to the other side of the road. Soon others followed him at the crossing and more people did the same. Just like chickens, they didn’t mind the honking horns(喇叭声) and kept crossing the road in a mess.
Every year several thousand people are either killed or hurt on the roads in Shanghai. And at least one third of them were jaywalking(乱穿马路). Jaywalking is very common in Shanghai. It seems that jaywalkers are not afraid of the danger to themselves.
Traffic laws are to keep people safe. So we should obey them, and have good road-crossing habits. When someone starts to jaywalk, we should stop him, and never follow him. That way we can avoid the traffic accidents.
The underlined word “intersection” here probably means “ ”.
| A．road | B．bridge | C．crossing | D．traffic |

A.However，some new illnesses will appear. B.Biotechnology（生物技术）will make food better and healthier. C.Some cities on water will have two floors. D.They will be much safer. E.They will have pictures that，as clear as photos. |
Cars will run on solar power or electricity and will be much cleaner.（1） For example，if you are too close to another car or if you are driving dangerously，your car will slow down by itself.
Since there won't be any spare place，new cities will have to be built in the sea.（2）
People will live on the upper floor，the lower floor will be used for traffic，shops and factories.
（3） Plants that are not influenced by insects （昆虫） or illnesses will be developed.The taste of fruit and vegetables will be better and food will be kept longer.

Many new ways to treat illnesses will be successful using products of genetic engineering （基因工程）.Treatments will be found for the flu （流感）and the common cold.（5）
If you had the chance to leave the life you have now, what would you do?
Students from Fair-grounds Middle School, New Hampshire, US, chose to lead a special life for a week. They left the city and lived a different life by working on a farm. They handed over their cell phones and lived like any farmer’s children. And they enjoyed it!
“I didn’t know what would happen when we got there,” said Tyler Swift, 14, “but there were so many fun things. So much hard work, too. It was a challenge.”
“Getting up at 6 every morning, the students milked cows, spread hay(放置草料), and washed hundreds of sticky buckets(黏黏的桶). The hardest part was cleaning up piles of poop(成堆的排泄物) in the animal houses. It smelled bad, but it was lots of fun!
None of the students said no to the work. “With the farmers’ help, they did the work better and better. And they learned a lot more than just farming work.” said Rick Brown, a science teacher at Fair-grounds.
“You get to know who can do what and learn to work with different people. The children all showed great team work.” said Nick Quadros.How long did the children work on the farm?

Going Green
Green is no longer just a color. It is a new way of thinking about the world and a way of living your life. It’s catching on all over the world. More and more people decide to “go green” because they know that we only have one planet to live on. We won’t be able to live on it much longer if we keep wasting energy, and destroying(破坏) our home with air, land, and water pollution.
“Green Living” means:
Understanding that your choices affect(影响) not just you, but everybody everywhere.
Understanding that your choices affect not just today, but the future.
Understanding that when we talk about “saving the planet” or “saving the environment,” we are actually talking about saving ourselves!
You may be thinking: “Hey, I’m just one person, on a planet with billions. I can’t really make a difference.” Well, have you ever seen a group of people do “the wave(波浪)”? It always starts off with one or two people, jumping up and down like crazy. Soon thousands of people are joining in. “Going green” is just like that. It starts with small, simple actions. It can soon build into a wave that will change the whole planet and lead us all to healthier, happier lives.
Many students have already shared with us their efforts to help the environment:
Gabrielle, 12, writes, “I have helped my community plant a garden and I ride my bike or skateboard to school.”
Kaitlyn, 10, says, “Lots of paper towels are thrown away, so I use a reusable cloth towel to dry my hands instead.”
“I always recycle(重复利用)” says Natalie, 13. “You can call me a recycler! I always look at the bottom of things. I want to see whether they have the little sign that tells you it can be recycled. So I almost recycle everything!”
Now it’s your turn to think about how you can “go green”. Make important choices and take actions to improve the environment right around you and the health of the whole world.What does the expression “catch on” in Paragraph 1 probably mean?
| A．Go worse. |
| B．Come to an end. |
| C．Get help. |
| D．Become popular. |
From the passage we can learn that ______.
| A．our choices can’t affect the future |
| B．one person can’t make a difference |
| C．our planet is destroyed by pollution |
| D．going green starts with small actions |
The writer may agree that ______.
| A．going green is hard for students |
| B．going green means changing others |
| C．going green is actually a choice |
| D．going green remains far away from us |
A new contact lens（隐形眼镜片）has been developed by scientists from America，Britain and China.It can check for illnesses at any time by examining chemicals in tears.A new sensor（感应器）is used to achieve his purpose.
Scientists hope that the improvement could help to deal with sudden medical events.Dr.Zhao Yunlong said， "COVID﹣19 has had a great influence on the scientific world.And we are doing research to help people deal with similar events in the future."
When introducing the new contact lens，Dr.Guo Shiqi，a researcher at Harvard，said，"In the past，the sensor was put between the layers（层）of the lens.It didn't have direct contact（接触）with tears，But our new sensor is smaller and smarter.I t can be fixed to a lens and keep direct contact with tears.What's more，it causes no discomfort to the eye.
The contact lens has not been put to the market，but researchers are quite sure that it will be welcomed.It is especially useful for the old and those who may experience sudden medical events.
As society develops，scientists are supposed to develop more products that provide care and convenience（便利）for people.The contact lens is one of what they are researching on.Earlier，a California company developed another kind of contact lens using LED technology.It can show the heath information on the mobile phone.Steve Sinclair，head of the company，said， "We have to build something that helps you when you need it and stays of when you don't need it."

Newspapers are dying.Electronic devices like mobile phones，pads，TVs and car radios can all be the killers.Most people believe in the long run，there is no reason• no practical reason for newspapers to survive.No matter what we do may only buy time.
Can anything save newspapers？I decided to have a try.
Many years ago，Bonnier，a Swedish publisher，set a newspaper in the former Soviet countries .After a few years，they had more newspapers in central and eastern Europe.However，these newspapers were run by a group of inexperienced people，and they didn't have enough money.In many places there were not even art directors.
I got a position in Bonnier's newspaper as an art director.
It was very difficult at first.I was really disappointed，until one day，in Londonn，when I saw performance by Cirque du Soleil. "These guys took some run﹣down entertainment，and put it to the highest possible level of performance art.M Inspiration lighted me up， "Why can't we do the same with the newspapers.We started to redesign the newspapers，one by one.
We used our imagination.We treated the whole newspaper as one piece，one composition - like music.
Music has a rhythm，has ups and downs.Design is responsible for this experience.Flipping through pages was readers' experience and I was responsible for this experience.
The front page became my personal channel to talk to the readers.My approach was simple and direct.I wanted to show my understanding of art，and of reality.I wanted to make posters，not newspapers.Not even magazines：posters.
We had determination，and we kept on trying.We experimented with type，with illustration and with photos.We kept asking：Why do we do it？What's our goal？
Design was not only about the front page.It was a part of the process.To be good was not enough.The process we made was about improving the product completely.
We adjusted the content accordingly.We improved everything to what our readers thought it should be and how they liked reading it.We kept improving and we had fun.
Soon in Poland ，our pages were named "Covers of the Year" three times in a row.One year later this newspaper，in the same country，they named it the "World's Best﹣Designed Newspaper".Two years later，the same award came to Estonia.The circulation of the newspapers kept going up.They became more and more popular.
Someone may think we are buying time，but our newspapers are alive，and growing.
（1）According to the passage，most people think newspapers .
| A． |
will be replaced |
| B． |
should be improved |
| C． |
need to be saved |
| D． |
may die immediately |
（2）Why did the writer go to work in Bonnier's newspaper？
| A． |
Art director was a well﹣paid position. |
| B． |
It would die and he was going to save it. |
| C． |
He hoped to get more working experience. |
| D． |
It was a big publishing company in Europe. |
（3）Which of the following is probably the writer's opinion？
| A． |
Newspapers can be alive if they are designed as posters. |
