Mr. Guo is a teacher from Xi’an. He asked his students to hand in their homework through a QR code（二維碼）. “We spent an hour or two in class learning how to generate（使產(chǎn)生）the codes, and in the end everything gets easier.” Said Guo. “When students finish the homework, they keep in on WeChat（微信）. Then, each student makes his own QR code and gives it to me. So I can check their work everywhere using my computer or telephone.”

The QR codes can be sent to Mr. Guo by email, QQ and WeChat. When Guo scans（掃描）his students’ QR codes, their homework appears on his phone. He finds that their homework becomes more creative（創(chuàng)新的）, with many pictures, music and even videos.

Guo’s students like the new way and think it is interesting. “We are living in the information age. Many students like to work with computers, which makes learning more fun.” said Tingting, a student of Guo’s.

“The paper is not easy to keep, but the code is easy to keep and share,” Guo said. “48 It is worth trying to use new technology in education. Education itself is a kind of creation. I don’t want my students to fall behind the times.”

However, some parents are worried. They are afraid that their children will spend too much time on computers and less time communicating with teachers. But in fact, it’s unnecessary. Students still need to look up information in books and write it down when they do their homework. They only use the code when they hand in their work, which doesn’t take them too much time. Also for teachers, it allows them to check the students’ work at any time. And it’s also an easy way to share homework with other students.

A. WeChat B. QQ C. email D. blog（博客）

4.Some parents are worried, because they think their children will _______.

A. talk with teachers face to face B. spend too much time on computers or phones

C. not like the new way of handing in homework D. find the QR codes too difficult to use

When we exercise hard, we burn fat. But have you ever wondered where exactly the fat goes?

Some doctors think that fat is changed into heat and given off in the air. Others think the body burns it. Some even joke that someone comes and takes it. That’s why you always weigh less in the morning.

Now a new study from Australia solves the mystery(迷). “The correct answer is that most of the fat is breathed (呼吸)out as CO2. It goes into the air.” says the study.

Scientists followed the atoms (原子) in 10 kilograms of fat as they are lost. They found that 8.4 of those kilograms are breathed out as CO2 through the lungs (肺). The other weight, 1.6 kilograms,becomes water and leaves the body.

“None of this is easy to understand because we can’t see the CO2 we breathe out.” said the study’s lead expert.

Does that mean you can lose more weight by breathing more? It is not as easy as you think.

Breathing more than the body’s metabolic rate (新陳代謝速度) can make you uncomfortable. You may feel dizzy(眩暈的) and become unable to see, move or feel, according to the study.

So how can people lose weight healthily? The key is to eat less and move more. You may have heard this many times. During a day, a 70kg person breathes out about 200g of CO2. So if the same person wants to lose weight, he or she can do some light exercise, for example, walking fast.This can help lose 240g of CO2.

1.Where is the new study from?

A. Japan. B. Australia. C. Canada. D. America.

2.According to the new study, where does our fat go when we exercise a lot?

A. The body burns it. B. Someone comes and takes it.

C. It is changed into heat and given off in the air. D. Most of it is breathed out as CO2.

3.What will happen to people if they breathe more than the body’s metabolic rate?

A. They will lose weight healthily. B. They will feel comfortable.

C. They may become unable to move. D. They may become healthier.

4.Which of the following is the best way to lose weight?

A. Sitting still and breathing more.

B. Sleeping a lot and breathing more.

C. Eating less and exercising more.

D. Eating more and doing some light exercise.

5.The passage mainly tells us ______.

A. where fat goes when we exercise B. why we can lose weight healthily

C. how we should do some exercise D. what we should do to become fat
