Dear Mike,
In your last e-mail,you asked me about the Science and Technology Festival in our school.I’m glad to tell you about it.
It was held on May 18th in order to improve our practical skills and develop our team spirit.Before the festival,the students were divided into groups and each team chose an activity.They did lots of experiments.
It was amazing to see eggs that had been dropped from a high place without breaking;the bridge made of paper was so strong that a person could stand on it;some robots could even dance to music.
The festival not only made us more interested in science but also brought much pleasure to our school life.
I’m looking forward to learning about your school life.
Yours,

Space vegetables are grown from seeds that are carefully chosen.When seeds are brought back from space,they are tested to make sure that they will be safe to eat.
Space vegetables are better for you than normal vegetables.For example,space tomatoes stay fresh for about twenty days,which is one week longer than normal tomatoes.

Lesson 25:Let’s Do an Experiment!
Ⅰ.阅读理解
(2021德阳)
As Internet users become more dependent on the Internet to store information,do people remember less If you know your computer will store information,why do you store it in your own personal memory,your brain Experts are wondering if the Internet is changing what we remember and how.
In a recent study,Professor Betsy Sparrow made some experiments.She and her research team wanted to know how the Internet is changing memory.
In the first experiment,they asked two groups of people to put 40 unimportant facts into a computer.The first group of people understood that the computer would store the information.The second group understood that the computer would not store it.Later,the second group remembered the information better.People in the first group knew they could find the information again,so they did not try to remember it.
In the second experiment,the researchers gave people facts to remember,and told them where to find the information on the Internet.The information was in an exact computer folder.Surprisingly,people later remember where the folder is better than the facts.When people use the Internet,they do not remember the information.However, they remember how to find it.This is called “transactive memory (交互记忆)”.
According to Sparrow,we are not becoming people with poor memories as a result of the Internet.Instead,computer users are developing stronger transactive memories;that is,people are learning how to organize a lot of information so that they are able to get it at a later date.This doesn’t mean we are becoming either more or less clever,but there is no doubt that the way we use memory is changing.
( B )1. Why does the writer begin the text with two questions
A. To explain some thoughts.
B.To introduce the main topic.
C.To show an opinion.
D.To draw the readers’ attention.
( D )2.What can we learn from the first experiment
A. Sparrow put the information into the computer.
B.Both groups remembered the information well.
C.Group 1 remembered the information faster.
D.Group 2 remembered the information better.
( B )3.What do we know about transactive memory from the second experiment
A.People organize the information like a computer.
B.People remember how to find the information.
C.People remember how to make a folder.
D.People keep the information in mind.
( B )4.What’s Professor Betsy Sparrow’s conclusion(结论)
A. People become more and more clever.
B.The way people use memory is changing.
C.The way people make experiments is changing.
D.People’s memories become poorer than before.

Here is an experiment to see how ants can organize some clever teamwork.
1.First you need some ants.You may have to wait until the summer to find them on paths around your home. 2.When you have found an ant,put a thin slice of fruit in front of it.It may eat some of it or carry bits away.
3.Check the fruit after an hour.Have other ants been attracted to it If so,what are they doing 4.When there are lots of ants,move the fruit to a new position,a little to the side.What do the ants do
What’s going on
You can see one of the best examples of insect teamwork by watching ants.If one ant finds food,it leads others there to eat it too.They follow each other by making long trails.The ants go back and forth collecting food to take back to their nest(穴).When you move the fruit,the ants will still find it.But instead of making a new direct route(路线) to the food,they will follow each other through their old trail route.

One way that scientists learn about man is by studying animals.In this lab,the scientists are studying the relationship between diet and health.
They are studying the relationship between the amount of food the mice eat and their health.The mice are in three groups.All the three groups receive the same healthy food.The first group eat one cup of food each day,the second group eat two cups,and the third group eat three cups.
After three years,the healthiest group is the one whose only eat one cup of food each day.The mice in this group are a little thinner.But they are more active.Most of the day,they are running and playing with one another.Also,they live longer.Mice usually live for two years.Most of the mice in this group are still alive after three years.
The second group of mice is healthy,too.They are active,but not as active as the thinner mice.They only live for about two years.
The last group of mice receives more food than the other two groups.Most of the day,these mice are eating or sleeping.They are not very active.These mice live longer than the scientists thought—about a year and a half.But they are not healthy.They are sick more often than the other two groups.
