Dear Tony,
Over the past months, the novel coronavirus has made its way around China. It has a strong impact on our life and study. In order to ease the serious condition, you can do as follows.
First, stay at home and don¡¯t go out unless necessary, which is good to yourself and others. Second, do wear protective masks if you have to go to the public places and wash hands as often as possible. Third, of course, taking exercise more often and taking good sleep to build your body are wise choices for you to reduce the risk of being infected.
A positive attitude is necessary, there¡¯s no need to panic, and keeping your spirits up can always make a big difference.
I truly hope my letter will help you.
Yours,
Li Ping

¡¾ÌâÄ¿¡¿ 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 released in the air. Others think the body burns it. Some even joke that the fat fairy comes and takes it. That is why you always weigh less in the morning.
Now a new study from the University of New South Wales in Australia reveals the mystery. ¡°the correct answer is that most of the mass is breathed out as carbon dioxide(¶þÑõ»¯Ì¼). It goes into thin air,¡± says the study¡¯s lead author, Ruben Meerman, to Science Daily. Scientists followed the atoms(Ô×Ó) in 10 kilograms of fat as they are lost. They found that 8.4 of those kilograms are breathed out as carbon dioxide through the lungs. The rest of the weight ¡ª1.6 kilograms¡ª becomes water that leaves the body in the form of fluids(ÒºÌå) such as urine(Äò), sweat, breath and tears. ¡°None of this is obvious to people because we can¡¯t see the carbon dioxide gas we breathe out,¡± said Meerman.
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(г´úл) can make you uncomfortable. You may feel dizzy and become unconscious(ÎÞÒâʶµÄ), according the study. So how to lose weight healthily? The key is to eat less and move more. You many have heard this many times.
During a day, a 70kg person breathes out about 200g of carbon dioxide. So if the same person wants to lose weight, he or she can do some light exercise, for example, jogging. This can help lose 240g of carbon dioxide.
¡¾1¡¿According to the new study, where does our fat go when we exercise a lot?
A.It is changed into heat and given off in the air.B.The body burns it.
C.The fat fairy comes and takes it.D.Most of it is breathed out as carbon dioxide.
¡¾2¡¿What will happen to people if they breathe more than the body¡¯s metabolic rate?
A.They will put on more weight.B.They will feel comfortable.
C.They may become unconscious.D.They may not lose weight at all.
¡¾3¡¿Which of the following is a better way to lose weight?
A.Sitting still and breathing more.B.Sleeping a lot and breathing a lot.
C.Eating less and exercising more.D.Eating more and doing some light exercise.
¡¾4¡¿Which is true according to the study from University of New South Wales?
A.The fat is changed into heat and released in the air.
B.Most of the kilograms of fat as they are lost are breathed out as carbon dioxide.
C.People can see the carbon dioxide gas we breathe out.
D.If we breathe more than the body¡¯s metabolic rate, we will feel good.
¡¾5¡¿During a week , how much carbon dioxide does a 70kg person breathes out?

¡¾ÌâÄ¿¡¿ Have you ever thought about making a bicycle that you dream of? Some creative people have invented some special bicycles. Here are three of them.
Bambikes Bambikes are produced in a company in Philippines. They are made of an unusual king of bamboo and other materials like metal and a local plant. They are very strong. And they are a perfect combination (½áºÏ) of the greenest building material and common bicycles. By making bambikes, the company offers jobs to the local people. Besides, it provides money for some students in its community to pay for their study. To continue the production, the company plants more bamboo than it cuts. |
The heaviest bicycle A German cycling lover, Frank Dose, has recently made the world¡¯s heaviest bicycle with big old wheels and lots of other waste materials. He created it just because of a bet (´ò¶Ä) he made with his friend. The bicycle weighed 1.08 tones. It broke the world record of its kind in weight. Frank said his bicycle was surprisingly easy to ride although it had a huge size and weighed a lot. He rode it in front of 5,000 people for over 100 meters to prove it. |
Twisted (±äÐεÄ) bicycles Two brothers in France created a bike that looks strange to ride and twists in the middle. Riders can make tight turns (¼±×ªÍä). The brothers say the bicycle is hard to ride so it can stop people from stealing it. In fact, it isn¡¯t as hard to control as you think. It takes a day or two to get used to the crazy way of riding. It¡¯s amazing. So far, there have 30 of the bicycle, but they are not for sale yet. |

Life is not easy, so I¡¯d like to say ¡°When anything happens, believe in yourself.¡±
When I was a young boy, I was too shy ¡¾1¡¿ speak to anyone. My classmates often ¡¾2¡¿at me. I was sad but could do nothing. Later something happened, and it changed my life. It was an English speech contest (±ÈÈü). My mother asked me to take part in it. What a terrible idea! It ¡¾3¡¿(mean) I had to speak before all the teachers and students of my school! ¡°Come on, boy. Believe in yourself! You are ¡¾4¡¿ (surely) to win.¡± Then mother and I talked about many different topics. At last, I ¡¾5¡¿the topic ¡°Believe in yourself¡±. I tried my best to remember all the speech and practiced it over 100 times. With my mother¡¯s great love, I did well in the contest. I could ¡¾6¡¿ [ha:dli] believe my ears when the news came that I had won the first place. I heard the cheers from the teachers and students. Those classmates who once looked down on me, now all said ¡¾7¡¿ [kngrtj'lenz] to me. My mother was very ¡¾8¡¿ (excite). She hugged (Óµ±§) me and cried.
Since then, everything has ¡¾9¡¿ (change) for me. When I do anything, I try to tell myself to be sure and I will find myself. This is not only for a person but ¡¾10¡¿ for a country.
