3 . Did you know that a seed (种子) can have its own “ID card”? The “card” shows that the seed is at the national crop germplasm bank (国家作物种质库) in Beijing, known as China’s seed bank.

A seed’s journey to the seed bank starts with a census (普查). China’s latest census of seeds started in 2021 and ended in 2023, reported CCTV News. Workers collected more than 139,000 new seeds from all over the country. They then arrived at the seed bank.

When seeds first come in, they each get a number for their “physical examination”. For example, workers put all kinds of corns from different farms together. Then they put them into groups according to the seeds’ look or taste.

Next, workers check the seeds to make sure they’re healthy and all the unhealthy ones are given up. A worker at the seed bank showed CCTV News a seed that had a large insect (虫子) inside it, “A seed like this should not be saved,” he said.

With the bad seeds gone, workers then test the good ones to see how likely they are to grow. The seed bank has a quick, smart way of doing this: Workers test the seeds and use the information they get to predict (预测) their growth. Workers dry and weigh the best seeds after several tests. Then, they’re stored in fridge at -18℃.

China’s seed bank keeps all the seed information safe and helps people learn about them. This can help develop new plants that can grow better and deal well with hard environments, ensuring (确保) the food safety of the country.

5 . ①Plants are more than just pretty to look at. They give us fruits, vegetables and food we eat. Some plants even provide materials for medicine or building things. But do you know that plants can do something even more amazing? They can make our homes, schools and workplaces much healthier. We spend a large part of our day indoors. Unluckily, the air inside buildings can often be full of a chemicals (化学物质) from many things around us. This poor air quality (质量) can make us feel sick, cause eye problems, and even make it hard for us to breathe (呼吸). When the air inside buildings gets really bad, people even call them “sick buildings”.

②The good news is that plants are like nature’s super heroes. They have a magic power fighting against bad air. Plants breathe in carbon dioxide (CO₂) and breathe out oxygen (O₂) which we humans need to live. They can also add moisture (水分) to the air if it’s too dry, making it more comfortable for us to breathe.

③ ▲ Scientists have discovered that plants have the ability to take in harmful chemicals, making the air around us safer to breathe. They set up a completely closed building called “bio-home” for experiments. Before they added plants, the air inside was full of chemicals and people found it hard to breathe. Then scientists added different kinds of plants in it. After a while, they used a special machine to test the air quality. The air got much cleaner and it became easier to breathe. People could go inside   without feeling unwell. Scientists found out the building wasn’t a “sick building” any more.

④So you see, plants are incredible! They are not only beautiful to look at, but they also provide us with food, help create materials and play an important role in our health. They make our indoor environments cleaner and healthier, making us feel better. Next time you see a plant, remember all the amazing things it can do for us!

I am sure you all know how important recycling is. Recycling is to collect the litter to produce useful things which can be     1     again. Even though it takes energy to recycle, it is actually worth doing it. Do you know     2     it works? Collecting things that can be recycled is the first step you have to do. Only some materials can be recycled. They are made of paper, metal (金属), glass and plastic. Can you think of everyday things made of these materials? Some bottles are a good     3    . They are made of glass. Magazines and newspapers are made of     4    . Let’s get back to the steps of recycling. Once you put all your things in a recycling bin, a truck comes to pick     5     up. Everything goes to a recycling company. There, these things are reused to make     6     products.

Now let’s take a closer look at how old paper is changed. First, the old paper is made into     7     pieces. Then a special kind of water with chemicals (化学制品) is put into them. And     8    , new paper is created! There are things written on the old paper,     9     they can’t be seen through this way.

Recycling keeps our planet     10    . It reduces waste. It also saves energy. So just remember the rule: always recycle your things.

7 . ① Some people are very careful about everything they do. However, some people are risk-takers — they usually do things without thinking too much about the results. For example, teenagers are especially likely to take more risks than others. Why is this?

② Van, a professor at Leiden University in the Netherlands, uses computer games to find out why some people are more impulsive (容易冲动的) than others. In one test, players are asked to click on a balloon on a computer screen. Every time they click, the balloon gets bigger. The bigger the balloon is at the end of the test, the higher their prize will be. But if the balloon gets too big, it’ll blow off and the player will get nothing.

③ Van found that when teenagers plays game, a part of their brain which is called the striatum (纹状体) would become much more active. It makes teenagers want to win. On the other hand, another part of the brain, the prefrontal cortex (前额皮质), helps them control their decision-making process (步骤).

④ It shows that young people have more active striatums and less active prefrontal cortexes which influence their ability to make careful decisions. You might have already guessed that teenagers would blow off more balloons during the test than adults—mainly because they are more likely to take risks and don’t take the time to think carefully.

⑤ “The brain of teenagers is like a car with a very strong engine,” Van said. “Its brakes just don’t work well enough to stop them quickly.”

9 . How does your teacher make you sit—in rows or in groups? How would you like to _______? Does sitting in rows make you feel good or does _______ make you feel lonely? Do you feel that sitting in a group and discussing things makes you learn more in an easier way?

In   the last 30 years or so, experts on teaching methods have _______ these questions. They felt that sitting in rows was not very useful to children, and that they learnt easier and better _______ they sat around a table in a group. That way, they could also learn to get along with others and exchange _______ easily.

_______, it seems they were not quite right. At least Nigel Hastings, professor of Nottingham Trent University, does not think so.
