In China, there is a prize called the Pineapple Science Award. 【小题1】 On Nov. 13, 2021, 10 fun studies received Pineapple Science Awards. Let’s look at three of them.

No big fan of music

The prize for medicine went to an international research team who studied mosquitoes (蚊子). Their study showed that the next time you see mosquitoes, perhaps you want to play music.

Researchers put mosquitoes and a hamster (仓鼠) together in two environments. 【小题2】 Mosquitoes waited longer to bite the hamster if they heard the music. It seems that they don’t like listening to electric dance music.

Contagious (有传染性的) behavior

When your friends check their phones, do you do the same? 【小题3】 Italian researchers found that looking at your phone makes other people around you do the same in less than a minute. This is because humans subconsciously (下意识地) copy the actions of other people. “We have a need to match our actions with those of other people,” said the researcher Elisabetta Palagi. 【小题4】

Smarter than humans?

We all know chimpanzees (黑猩猩) can be quite clever, but we probably don’t think they could beat university students in math. 【小题5】 Comparing a chimpanzee named Abu and a group of university students, the researchers found that Abu could remember numbers more quickly and more correctly than the students.

TV news programs report the weather. Radio stations tell us the weather, too. Newspapers show us weather forecasts (预报) on maps.

Why do people want to know about the weather? Because people want to make plans. Some people want to have a good time with friends. Other people want safety while doing their jobs.

Airport managers need to know about the weather. In bad weather, their planes cannot fly. Farmers need to know about the weather. In bad weather, they must protect their crops. Fishermen need to know about the weather. In bad weather, they can’t go out to fish.

Computers help us know about the weather. They get new weather information quickly. They can use this to predict how the weather might change. Unfortunately, we can still only guess the weather. Sometimes, we have difficulty in knowing about the weather. Then we will make wrong plans. We all hope that the weather will be easier to predict in the future.

Have you ever thought about your body changes(改变)? Up to about the age of eight or nine, girls and boys look quite alike. They have similar(相似的) shaped bodies and their voices sound almost the same. As they grow, all their organs(器官) grow, too.

At the same time after the age of ten, often at eleven or twelve, boys’ and girls’ bodies start changing. This time of change is called puberty(青春期). The changes mean their bodies are getting ready so that they’ll be able to have children when they’re older.

The changes don’t happen to everyone at the same time. Each person has his or her own body-changing timetable. By the time they’re eighteen, they should be complete(完整的). Girls start changing some years sooner than boys. Until they’re fifteen or so, they grow faster than boys of the same age. As years go by, boys can catch up and grow taller and stronger. Girls grow taller and heavier as well, their faces and breasts become fuller. As well as all the changes you can see happening, other important changes—ones you can’t see—are happening inside your body at the same time.
