Have you ever rubbed your hands together when they get cold? Why do we do that? We do that for friction. Friction happens when two things that aren’t very smooth (光滑的) rub together to make heat energy. The faster you rub two things together, the more friction you can make. Let’s discover friction!

Should Shanhai bid for(申办)the Summer Olympics in 2028? Here are some people's opinions.
Some people said,“The games will improve Shanghai's global influence and the city is powerful and must try to become a platform(平台)for major international dialogues, Shanghai has succeeded in holding the World Expo in 2010 and the city can also hold the successful Summer Olympics. "
Others, however, are not sure that it's a good idea. They think the Olympics would be too expensive and the money could be better spent on other things.
The 2008 Beijing Olympics brought much prestige(声望) to the city and to China, but its cost, over $40 million, was high and the Olympic site(场地) in the center of the city is now largely unused, Could Shanghai learn from Beijing's experience and do it better?
My answer is yes. As one American said, "A great city has to do great things. " Shanghai is a great city and is not afraid of facing challenges. Holding the 2028 Summer Olympics would prove that.Shanghai held the World Expo in 2010 successfully.
The Olympic site in the center of Beijing is now largely used.
The 2008 Beijing Olympics cost more than $40 million.
All people think it is a good idea for Shanghai to hold the Summer Olympics,
The writer thinks Shanghai can learn from Beijing's experience and do it better.
One day, I heard an American boy said to a Chinese girl student, "You speak very good English. " But the girl answered, " No, no. My English is very poor. " The foreigner was quite surprised at the answer. Thinking he had not made himself understood or the girl had not heard him clearly, he said, " Yes, indeed, you speak very well. " But the girl still kept saying, "No. " In the end, the American boy could not understand and didn't know what to say.
What's wrong with the girl's answer? She didn't accept a compliment(夸奖) in the same way as the American people do. She should answer, "Thank you" instead of “No". She really understood what the American boy had said, but she thought she should be modest. In the west, people will feel proud and confident when they are praised. So if someone says the dishes you have cooked are very delicious, you should say, "Thank you.”
In our country, we think being modest is a virtue(美德)and being proud is a bad thing, but in my opinion, being confident does not mean being proud, so sometimes you should be confident instead of being modest.
If you are modest and say, "No, I'm afraid I can't do it well", while working in a western country, the others may think that you really cannot do it. If you often say, “No”, you will certainly be looked down upon by others. When asking for a job, if one says something like‘'Yes,I can certainly do it”instead of “let me have a try”,he or she will expect to get it. So in the west, you should be brave to show your self-confidence。Why did the Chinese girl say“No”when she was praised?
A.Because she thought she should be proud. |
B.Because she thought she should be confident. |
C.Because she thought she should be modest. |
D.Because she thought she is a student. |
If you say,“I can do it well.“when asking for a job in the west,the others may think that __________.
A.You can do it well. | B.You can't do it well. |
C.You like doing it. | D.You don’t like doing it. |
What does the underlined part“looked down upon”mean in Chinese?
A.瞧不起 | B.瞧得起 | C.表扬 | D.批评 |
Which of the following is true according to the passage?
A.The girl didn’t hear the boy clearly. |
B.The American boy understood the girl’s answer. |
C.In China, people think being modest is a virtue. |
D.The writer thinks being modest means being proud. |
What does the writer want to tell us?
A.We should be proud and selfish in the west. |
B.We should be modest and confident in the West. |
C.We should be modest and brave in the West. |
D.We should be brave and confident in the West. |

The teacher called a meeting of the students. When they had arrived, he said to them, "You are good boys who know what is right and what is wrong. If you leave, you will have no trouble in joining any other school. But what about your brother who does not even know the difference between right and wrong? Who will teach him if I don't? No, I cannot ask him to go even if it means losing all of you. "

Steve Jobs was famous for starting Apple Computers. In a speech to graduating students at Stanford University, Jobs told students about some of life-changing experiences. Jobs believed these experiences helped him achieve success.
Job’s biological mother was a college student. As a young mother, she felt unable to bring Jobs up so she put him up for adoption. Job’s adopted parents were simple working-class people. When Jobs was 17, his parents used their saving to send him to college.
After six months of college, Jobs decided it was not for him. Around that time, he had read a quotation that went something like,“If you live each day as if it was your last, someday you’ll most certainly be right.”The quotation made him think about his life and his future. He started to question if he should stay in college. Was he doing what he really wanted to do? Eventually, he decided he had to change something; he decided to drop out of college.
Jobs was lucky because he knew what he loved to do. He started Apple Computers in his parents’ garage with a friend when he was 20. In just ten years, Apple grew into a $2 billion company. However in 1985, Jobs was fired from the company.
Jobs was shocked. He lost everything at once. He quickly realized that he still loved what he did, and over the next five years, he started two highly successful companies. next and Pixar. Jobs also met his future wife, Laurence. Jobs was happily married with a family, working for Apple again and living every day as if it were his last.
