Playing with apps on smart phones is very common among young people. Let's try some special apps and enjoy them.

    IQ scores have been measured (测量)since 1916, when Alfred Binet developed his intelligence list as follows:

    Some very famous people are known for their high IQ level. Jill St. John who has the highest score on this list was a major American film actress during the 1960's and 1970's. Jill was chosen to the University of California at the age of 14.

    Scientists have estimated (估算)the IQ scores that some famous historical people might have got. This was done by looking at their work and their ideas and the way they put them together Leonardo da Vinci gets that high score not only for his art but also for his idea of the helicopter (直升飞机). Without modern scientific tools, he created a lot of design drawings and patterns, which was ahead of his time.

    How important is your appearance? Although everyone wants to be good-looking, are beautiful people always happier people? For example, it must be a problem to be a really beautiful woman, because some people may be more interested in looking at you than talking to you. They think of you as a picture rather than a person.

    Some people think that women who are exceptionally(格外地) pretty and men who are particularly handsome must be stupid. They believe that only unattractive(无魅力的) people can be intelligent(智慧的).

    On the other hand, no one wants to be really ugly, and have a face that even your mother doesn't want to look at; and no one wants to be plain, either--that is, to be neither attractive nor unattractive, and have a face that is easily forgotten. Being attractive is like being rich. It can help you find happiness, but it doesn't always make you happy.

    So maybe the best thing is not to worry too much about how you look, but simply try to be an interesting person. For interesting people have interesting faces, and interesting faces are almost always attractive.

Do you like to have any online classes? It is becoming 1 to take classes at home during the early 2020. All you need is a computer or a cellphone. However, most students don't seem to like online classes. A 2 shows that only 33% of over 1,500 students from 10 cities would take such classes.

Many students said it was difficult to focus(集中) on 3 while taking online classes. Lian Ruohan, 15, at the Affiliated High school of Peking University, said, "There are no real classmates sitting near me; no real teachers watching me. I can easily surf the Internet or do 4 things if I want to. It's harder to be always focused."

In order to avoid that, Lian will prepare a lot before classes to make sure she will learn 5 in class. She also pushes herself to communicate(沟通) with teachers about difficulties. She often 6 or answers questions while taking online classes.

Wen Jiayi, 14, at the Yucai Middle School, thinks online interaction(互动) isn't 7. "I have few chances to communicate with the online teachers, and they don't really get to know me. When I don't hand in homework, all I get is only a short telephone 8 instead of real care," she said.

However, Lian thinks online classes still have many 9. "It saves time and money compared to(和……相比较) taking official classes. Also, if I can't 10 some part of a lesson, I can watch it again to make it clear."

School education is very important and useful. Yet no one can learn everything at school, {#blank#}1{#/blank#} teacher can't teach his students everything they want to know. His work is{#blank#}2{#/blank#} (show) his students how to learn. He teaches them {#blank#}3{#/blank#} to read and think. So much more is to be learned outside school by the students.

It is always much {#blank#}4{#/blank#} (important) to know how to study by oneself. It is quite{#blank#}5{#/blank#} (easily) to learn something, but it is difficult to use it to solve problems. Great {#blank#}6{#/blank#} (invent) do not get everything from school, {#blank#}7{#/blank#}  they still invent many things and change the world a lot.

How can the inventors do all of this? One of the answers is that they know how to study. {#blank#}8{#/blank#}  fact, a lot of things are not learnt in the classroom. They get a lot of knowledge by {#blank#}9{#/blank#} (read) outside school. They work hard and never give up all {#blank#}10{#/blank#} (they)lives.

Many people catch a cold in the springtime or fall. Although scientists can send a man to the moon, why can't they find a way to stop the common cold? The 1 is easy. There are actually hundreds of kinds of cold viruses（病毒）out there. You never know which one you will 2 , so there isn't a cure（治疗）for each one. 

When a virus gets into your body, your body works hard to fight against it. When you have a cold, blood（血液）rushes to your nose and makes it stuffy（堵塞的）. You feel 3 because you can't breathe well, but your body is actually "eating" the virus. Your temperature rises and you get a fever, but the heat of your body is 4 the virus. You may feel uncomfortable, but actually your wonderful body is doing everything it can to kill the cold. 

Different people do different things to deal with colds. In the United States and some other countries, for example, people might eat chicken soup to feel 5 . Some people take hot baths and drink warm drinks. Other people 6 medicine to stop the uncomfortable feelings of colds. 

There is one interesting thing to note—some scientists say taking medicine when you have a cold is actually 7 for you. The virus stays in you longer because your body doesn't have a way to 8 it and kill it. Bodies can do an amazing job on their own.
