The Internet has got into all the fields of our life. We can study and work on it. We can find a job on it. We can communicate on it. We can treat friends on it. We can buy and sell on it. We can do almost everything on the Internet, and almost anywhere, anytime.

However, although the Internet provides services for us, it is silently getting our privacy(隐私) to some degree. The services on most websites require our personal information. If we want to enjoy these services, we have to provide much of our information, including our names, sex, addresses, telephone numbers and sometimes bank accounts(帐户). Because weak network sometimes is unsafe, our information might be open, stolen or sold. Even sometimes it will be used freely by others.

Considering（考虑到...） the above mentioned, you must pay attention to the safety when using the Internet. First, when you need Internet service, you should always look through those big legal(合法的) websites. Second, if the service requires important personal information, you should think twice before you type it in. Third, store your own important card key(电子钥匙) and don’t tell others easily.

1.According to the passage, we shouldn’t ______by using the Internet.

A．learn English	B．give our friends’ information to others
C．chat with friends	D．look for jobs

2.The underlined word “it” refers to ______.

A．the telephone number

B．the name

C．the information

Last week, President Barack Obama gave a back- to-school speech to students at the Julia R. Masterman Laboratory and Demonstration School in Philadelphia, Pennsylvania. Students in schools across the country al­so tuned in to watch the President's speech on TV. He stressed the importance of trying new things, working hard and believing in yourself.

While admitting that times are tough for families across the country, Obama reminded students that hard work now can mean big success later. “Nobody gets to write your destiny(命运）but you,” he said. “Your future is in your hands. Your life is what you make of it. And nothing—absolutely nothing—is beyond your reach."

Obama spoke about his own life, and lessons he learned from his mother, who had to remind him to stay focused on his studies. He told students the recipe (诀窍) for success: “Showing up to school on time. Paying attention in class. Doing your homework. Studying for exams. Staying out of trouble. ”

Obama encouraged students to embrace(欣然接受)what makes them different. “We shouldn't be em­barrassed by the things that make us different,” he said. “We should be proud of them.”

He also suggested taking advantage of all of the opportunities at your school, and always being open to trying new things. “Just because you’re not the best at something today doesn't mean you can't be tomorrow,” he said. “Even if you don't think of yourself as a math person or as a science person—you can still excel in those subjects if you're willing to make the effort. And you may find out you have talents you’d never dreamed of.”

1.What does Obama mainly want to tell the students in Paragraph 2?

A. Some families are experiencing a hard time.

B. Different people have different destinies.

C. They can create their own future.

D. Those who don't study hard will achieve nothing.

2.In Paragraph 3, Obama tried to encourage the students by _______.

A. telling an interesting story

B. sharing the secret to success

C. telling his own life experience

D. referring to some famous people

3.Obama suggested the students should   _________ .

A. not study hard for high marks

B. accept things that make them different

C. do what they are really interested in

D. not do things which are difficult for them

4.The underlined phrase “excel in” in the last para­graph means “_________”.

A. be careful with                                                   B. be attracted to

C. be interested in                                                 D. be good at

 

It’s not easy growing up. Growing up can be a real “pain” for some of us. Sometimes we feel trapped, sometimes we feel sad, sometimes we are fearful, and sometimes we just don’t understand why we can’t stay young forever. But we should take a look back on all the hardships in life with a positive attitude and learn from them. We must overcome every obstacle one small step at a time. We should realize that all of our growing pains actually turn into growing gains!
Throughout our lives we are going to face many challenges and pains, but we should never let these obstacles keep us from following our dreams. We must overcome every obstacle one small step at a time.
As a young girl, my parents forced me to do so many things that I didn’t like. They made me learn to play the violin and then the piano. At that time I hated music and I also hated them. But looking back now, I am so glad that my parents encouraged me to take music lessons. Music has enriched(丰富) my life in so many ways. I now realize that my parents and teachers wanted me to have a better life than they did themselves.
We are all going to experience growing pains, but they are just part of our life. They might seem so huge at the time, but we must be strong. Think about how we would feel if we had no challenges and lived a life like that. Life would be really boring and meaningless. The future is ours! A little hard work and sweat never hurt anyone! If we realize that these pains are just small bumps(碰撞) on our road to success, we will realize that our growing pains are actually growing gains!
【小题1】 The underlined word “obstacles” (in Paragraph 2) roughly means things that ______.

A．are related to your studies

【小题3】We can know from the last paragraph that _____________.

A．life without challenges is dull

B．life needs no pains but sunshine and happiness

C．we should give up faced with challenges as the future is ours

D．we shouldn’t easily pay a little hard work in growing up

【小题4】The purpose of the passage is to tell readers____________.

A．life is full of hardships

B．growing pains can turn into growing gains in a positive way

C．everyone is painful in growing up

D．everyone should do what they don’t like when young

ScienceDaily (May 28, 2010) --- Researchers at Oregon State University (OSU) have made important progress in work that should lead toward robots that can not only walk and run very well, but use little energy at the same time.

Studies are moving closer to designing robots that could do dangerous work, create prosthetic limbs（假肢）for humans that work much better than in the past, or even help some people who use wheelchairs to get “walking” abilities.

“Researchers have been working toward robot movement for a long time,” said Jonathan Hurst, a professor at OSU. “What we’ve done is to study what behavior is really possible for a robot.”

The movement of humans and other animals is difficult to copy. Using little energy, they can move easily over hard areas, and enjoy balance from muscles（肌肉）. They have different ways to deal with forces, such as holding something hard in place rigidly（牢牢地）, like the act of holding a cup of coffee level during a car ride. In their recent studies, the OSU researchers proved that these two abilities are mutually exclusive（相互排斥的）. Humans deal with this problem by using pairs of muscles. For a robot, the more it’s able to do one of these tasks, the less able it is to do the other.

Presently, robots that can walk and run must be as rigid as possible while walking. But this way uses a lot of energy. The OSU researchers are working toward something that has similar or better performance, but uses far less energy, and is closer to the abilities of animals.

“So there’s no reason why we shouldn’t be able to build robots with good movement ability,” Hurst said. “Clearly this might be useful in highly dangerous situations. But I could also see great improvements possible with prosthetic limbs that work much better than present technology. ”

A. are successful now

B. use little energy

C. do better than before

D. can run faster than humans

A. walking and running

B. walking and holding

C. moving and using little energy

D. moving and balancing

75. 4.According to Jonathan Hurst, we know that robots with good movement ability ______.

A. can be used in medical science

B. are only used in highly dangerous situations

C. will hardly be created in the future

D. will have a bad influence on man

 

     Handshaking, though a European practice, is often seen in big cities of China. Nobody knows exactly when the practice started in Europe. It is said that long long ago in Europe when people met, they showed their unarmed (无武器的) hands to each other as a sign of goodwill. As time went on and trade in cities grew rapidly, people in cities began to clap each other’s hands to make a deal or to reach an agreement. This practice was later changed into shaking hands among friends on meeting or leaving each other. “Let’s shake (hands) on it” sometimes means agreement reached.

     Do the Europeans shake hands wherever they go and with whomever they meet? No . Sometimes the Chinese abroad reach out their hands too often to be polite. It is really very impolite to give your hand when the other party, especially when it is a woman, shows little interest in shaking hands with you and when the meeting does not mean anything to him or her. Even if, for politeness, he holds out his unwilling hand in answer to your uninvited hand, just touch it slightly. There is generally a misunderstanding (误解) among the Chinese that westerners are usually open and straightforward, while the Chinese are rather reserved (保守的) in manner. But in fact some people in western countries more reserved than some Chinese today. So it is a good idea to shake hands with a westerner only when he shows interest in further relations with you.

64. In the old days in Europe, people put out their unarmed hands to each other ______.

A. to make a deal                                                   B. to greet each other

C. to show friendliness                                            D. to reach an agreement

65. The first paragraph mainly tells us ______.

A. where handshaking was first practiced           

B. how handshaking came about

C. about the relationship between handshaking and trade

D. about the practice of handshaking both in Europe and in China

66. According to the text which of the following statements is true?

A. Westerners are more reserved than the Chinese.

B. Westerners are unwilling to shake hands.

C. We should make a judgment before shaking hands.

D. We shouldn’t shake hands with European women.

67. The main purpose of the text is ______.

A. to tell us some differences between the East and the West

B. to offer us some important facts about handshaking

C. to introduce us to some different customs in the West

D. to give us some advice before we travel abroad
