When do children start to talk？If you ask a group of parents when this happened，most will say" around twelve months of age".They will probably even remember what the children said.Many parents keep a diary of their child's "first words"
We can never predict what a first word is going to be.Often it's the name for" mummy " or "daddy"，but it could just as easily be the word for an animal or a favorite toy.Everything depends on what has most caught the child's attention.But one thing is certain：after the first word，others come quickly.By 18 months，most children have learned about 50 words.By two，the total has risen to around 200.
Early words are actually one﹣word sentences.One of the first features（特征）of language a child learns well is to control the rise and fall of the voice to make the difference between stating and questioning.In English，daddy with a high rising tone（声调）means "is that daddy？" Daddy with a high falling tone means "There's daddy".Of course，only very basic meanings can be communicated using tones alone.So it soon becomes necessary to learn some grammar.
In English，grammar means learning to put words in different orders.Children have to see that mummy push is different from push mummy.They start practising such changes at around 18 months.By two，they have learned the basic patterns of word order，and we hear them saying such things as man kick ball and where daddy go.
What are the parents doing all his time？They're acting as teachers and they always have an active role to play in their child's language learning.

Tangchang，a town in Chengdu，is well﹣known for cloth shoes.With over 20 types，Tangchang cloth shoes are strong，comfortable，breathable and friendly to the environment.In 2018，they were added to Sichuan's intangible cultural heritage list（非物质文化遗产名录）.
63﹣year﹣old Lai Shufang has spent over 40 years making Tangchang cloth shoes.Now she is a master.She said there are 32 steps to make a pair，but the most important step is making the soles.

Lai's hard work touched her son Ai Peng.In 2015，Ai decided to leave his job and help his mother.He used Shu embroidery to make the shoes look more beautiful and opened a cloth shoe store online.He also set up shop windows to show the steps of making shoes，helping more people learn about the art of cloth shoes.

Have you ever bought something and then changed your mind？For Alison Jenson，15，this used to happen several times a week.Alison was a shopaholic.She just couldn't stop shopping and she loved special offers.
Alison's bedroom is full of stuff. "I've been to every shop in Birmingham，I think， "says Alison.She picks up some earrings.The labels are still on them. "These were half price， "she says. "I've never worn them. "Alison's problem wasn't just jewellery.She also bought a lot of clothes，though not many shoes，because they were usually too expensive.She has also bought lots of other small things - like 20 new covers for her phone.She hasn't used any of them.
According to experts，we all feel excited after we buy something new.For shopaholics，it's a little different.Soon after they buy something，they think they've made a mistake and start to feel unhappy.So they buy themselves something else to feel happier.

Alison knew she had a problem. "I often bought something every day.Usually it was something small，but I just needed to buy it， "she says. "I spent money that I got for my birthday，and when I was short of cash，I borrowed money from friends or my parents.When I couldn't go shopping，I felt anxious.Then one day，my parents just looked at all the stuff in my room and said，'This is crazy!' I knew theywere right. "I needed some big changes in my life.
Alison now gets help with her problem and feels she has changed.She no longer thinks she's a shopaholic. "When I want to buy something in a shop，I ask myself two questions， "she says. "Do I need it？Can I afford it？The answer to both questions is usually 'no'，so I walk away.It's great!"

Everything is made of something.Nothing is made of nothing.
Chemistry is about the smallest things that other bigger things are made of，and what happens when theychange.The word chemistry comes from chemical，which is an example of one type of the very small things that other bigger things are made of.The words you are reading now are made of a dark liquid called ink （墨水），which is written on paper.The paper itself is made out of the chemicals that wood is made out of.Both the ink and the paper were made by different chemical processes.A chemical process is what happens when chemicals come together to make other chemicals，and therefore other things.
Cooking makes chemical changes.Your different ingredients are made of different chemicals，and when you put them together and make them hot and cook them，the chemicals change into new chemicals and the different ingredients make something new.That tomato sauce you're making is made of tomatoes，onions，garlic，salt and pepper.Those ingredients each have their own chemicals and their own flavors，but now with your sauce you've made something different，something that has its own flavor，all the ingredients mixed together，all the chemicals mixed together，something new.
You can smell the chemical changes，too，as they go up into your nose，especially when you forget about your sauce and it doesn't just cook but bums and becomes black and has a really bad flavor.You can't make it better，either，because once chemicals change，they can't be changed back again.

"My favorite thing about the pangolin is the scales （鳞片）it has on its body.They look cool， "Landon said.
Landon first learned about pangolins from a TV show，Wild Kratts.Knowing that pangolins are facing the danger of dying out，Landon quickly decided to take action to protect them.He wanted to tell everyone he knew about them.On Halloween，he had his parents carve （雕刻）a pangolin into their pumpkin（南瓜）so that when people asked what it was，he could tell them all about his favorite animal.When Christmas came around，Landon had only one wish：to save the pangolins.His parents had him "adopt （领 养）" a pangolin in Landon's name.They also came up with a good idea.They helped Landon make Christmas gifts to sell to help raise money for the pangolins at a market.So far，he has raised ＄ 400.

Most viruses can be found and killed by our immune system as soon as they enter our bodies.However，some viruses，for example，the coronavirus，are sneaky.They are difficult to recognize and find.These viruses can cause deadly diseases，like COVID﹣19.Human﹣to﹣human transmission can easily occur，and pandemic will therefore break out.Vaccination is by now a simple，safe and effective way to protect us from the diseases.
▲Vaccines are something that "looks" exactly the same as the viruses，mainly made from the viruses that are weakened or killed.They will not make us really ill.They only stimulate and activate our immune system to work，telling it something harmful is coming in.The immune system will know what the "viruses" look like，and send B cells（lymphocytes）or antibodies to find and kill them.Meanwhile，B cells will remember them for the next kill.A vaccine may also give us passive immunity by providing B cells taken from an animal or a human to play the same role.
Scientists have developed more than 180 vaccines to fight against COVID49.The technical approaches of these vaccines can be a little different，but their aims are the same.
Take the inactivated vaccine as an example.In an inactivated vaccine，the coronaviruses are already killed or made into the ones unable to produce more new viruses.When the immune system "sees" them，it will try to kill them.The question is：without enough these viruses• how can B cells remember them？That's why we need to take the vaccine more than one time.Though this vaccine is safe，it might not be as effective as it is expected to be.
The live﹣attenuated vaccine is different.In this vaccine，the viruses are weakened，but they are alive.They can produce enough new viruses to train the immune system to kill and remember them，so people only need to take the vaccine once.The live﹣attenuated vaccine is considered the most effective，but there is a worry：what might happen once these viruses wake up？
Therefore，although vaccination is by now one of the best ways to protect us from COVID﹣19，it can be better.
（1）The coronavirus can .
| A． |
not be killed |

Marianne Carus，who started Cricket（蟋蟀）magazine in 1973 and served as Editor﹣in﹣Chief（总主编）until 2012，died on March 3 at the age of 92 this year.
Marianne believed that "only the best of the best is good enough for the young. "In Cricket，children would find wonderful stories with beautiful art，and be encouraged by ideas in the humanities and sciences.Marianne looked for stories from around the world to awaken admiration for different peoples and cultures.Most important，Cricket would never talk down to children.
Marianne knew that children were filled with fun，and she wanted Cricket to be，too - "humor from the heart that makes you laugh out loud. "And so she named her literary magazines after a funny group of bugs（虫子），such as Lady bung and Spider.
Over the years，Cricket has been read by millions of children and given many writers and artists their start.Marianne kept a special box of "love letters" to the magazine.She treasured these letters from Cricket readers，including long﹣ago readers.They told her that their interest in reading had begun with Cricket.
▲She considered other names，such as Troubadour or Taliesin，the singers and storytellers of old who traveled from one place to another to share their songs and stories.Then，one night，she was reading Isaac Bashevi Singer's memoir（回忆录）A Day of Pleasure，about his childhood in Warsaw.In it he wrote：There was a stove in Shosha's apartment behind which there lived a cricket.It chirped the nights through all winter long I imagined the cricket was telling a story that would never end. "That's exactly what Marianne wanted her children's magazine to do-to tell stories that would never end!So the name Cricket became her best choice.

Have you ever entered a tropical rainforest（热带雨林）？Rainforests make up only a small part of the Earth's surface，about six percent，but there are more kinds of tees than any other area in the whole world.
Tropical rainforests are in Africa，Asia，Central and South America，Australia，and on the Pacific islands.The largest tropical rainforest is the Amazon（亚马逊）Rainforest in South America，which covers 1.2 billion acres，or almost five million square kilometres.The second largest rainforest is in Western Africa.
Rainforests provide us with many things.In fact，the Amazon Rainforest is the "lungs of our planet" because it produces 20%of the world's oxygen （氧气）.One fifth of the world's fresh water is also found in the Amazon Rainforest.Furthermore，one half of the world's species of animals，plants and insects live in the Earth's rainforests.80% of the food we eat first grew in the rainforest.25%of the drugs we take when we are sick are made of plants that grow only in rainforests.Some of these drugs are even used to fight and cure cancer.
There are four different levels of trees in a rainforest.The forest floor is the lowest layer full of animal life and receives the least amount of light.The under storey is the dark，cool environment under the leaves but over the ground.The canopy layer is the upper parts of most of the trees.The emergent layer contains a small number of very tall trees.
These different parts of a rainforest exist together to create an ecosystem for many animals，plants and human beings.

When most people decide to buy food, they go to a grocery store. Grocery stores sell many different kinds of food in just one store. Some grocery stores also sell household goods such as kitchen paper, cleaning things, and diapers （尿布）. A grocery store is a convenient place to shop for the kitchen and others.
Although it is comfortable and relaxing to shop at a grocery store, some people decide to buy their food from other places like farmers' markets. At a farmers' market, local farmers sell the foods they grow to customers. The foods they sell often include fruits, vegetables, and meats. Most of these foods are freshly harvested（收获）with no man-made additions.
There are several ways in which farmers' markets are less convenient than grocery stores. For example, packed foods usually are not sold at farmers' markets. Besides, many farmers do not accept credit（信用）cards or checks （支票）as payment for their goods. What is more, most farmers' markets are only open for business once or twice each week. This makes some people not want to shop at farmers' markets, but others are willing because of the fresh and local food there.
Deciding whether to shop for food at grocery stores or at farmers' markets is a personal choice. This choice reflects a person's values about life and about food. Those who value convenience and（多样）will probably choose to shop at a grocery store. People who value freshness and enjoy supporting local farmers will probably prefer the farmers' markets.
