Although we can’t know for certain how the earliest human beings kept track of the time, scientists believe they probably relied on the natural world around them. For example, historically, humans have relied upon the movement of the sun across the sky to track time. The ancient Egyptians built tall obelisks (方尖碑) that would cast shadows to help divide the day into sections.

These obelisks worked in much the same way as sundials (日晷), which were a popular means of timekeeping long ago. Of course, sundials didn’t help much at night or on cloudy days. To help keep time when it wasn’t sunny, ancient people also learned to track the movement of the planets and constellations (星座) after dark.

Other devices were developed over time, including hour glasses and water clocks. These devices relied upon the time it would take a particular substance (物质), such as sand or water, to move from one part of a container to another. Rather than clocks, though, these devices were more like timers.

How did people long ago set up a meeting at a certain time in the future? Some historians believe many people relied on a technique as simple as pointing to an area of the sky. When the sun reached that point, that’s when you would meet the next day.

Of course, humans, being the clever creatures we are, relied on a variety of natural solutions to the problem of timekeeping. For example, many people simply trained their bodies to wake up at the first light of dawn. Others may have relied upon animals, such as roosters, as alarm clocks.

If people had to be up before dawn, they might have depended on the full bladder (膀胱) method. By drinking a lot of water before going to bed, they would be assured of waking up in the middle of the night to go to the bathroom!

1.What do the examples suggest in Paragraph 1?

A.It was hard for people to track time.

B.The sun was important to people’s life.

C.People tracked time by the natural world.

D.The sun had something to do with time.

2.What might be helpful when people get together in the day?

A.The animal calls.

B.The shadows of obelisk

C.The position of the sun.

D.The planets and constellations.

3.Why did some people drink too much water at night?

A.To get up on time. B.To wake up at dawn.

C.To prevent thirst. D.To go to the bathroom.

4.What would be the best title for the text?

A.When did Clock Appear?

B.Why is the Sun Important?

C.Where does Clock Come From?

D.How did People Keep Time before Clock?

We don’t know how different our future will be in the future. We can only try to imagine it.

At first we think about human relationship. In the year 2050, we will use computers almost every day. We will be making new friends through the Internet----even our husbands or wives will be met in this way. It will be much faster and easier for us. On the other hand, our relationships with people won’t be as important as they are today----we will feel a little lonely.

Computers will also help us in many other activities in 2050. For example, they will be used by the children at school to make their learning easier. In addition, there will be much more other machines which will play a similar role as computers, like robots which will do the housework for us.

Spending holidays will also be completely different. Traveling to other planets or to the moon will be available for everyone. Means of transport will, of course, change, too. We will be using solar-powered cars, which will be much more environmentally friendly.

We could expect that the faster technological progress would lead to a more polluted environment. But it isn’t true. We will pay more attention to protecting the environment. And, scientists will probably find cures for many dangerous diseases, like cancer or AIDS. Therefore, our surroundings as well as our health will be in a better condition.

Although we can’t predict the exact changes which will be made in the world, we often think about them. We worry about our and our children’s future; we have expectations, hopes as well as fears. But I think we should be rather sanguine about our future. We should be happy and believe good things will happen.

1.Why will people probably feel a little lonely in 2050?

A. Because the number of people will become much smaller.

B. Because people won’t communicate with each other much often.

C. Because people won’t like making friends with each other.

D. Because there will be less face-to-face communication.

2.According to the passage, which of the following will happen in 2050?

A. It won’t be difficult for people to travel to other planets.

B. The way of spending holidays will be the same as that of today.

C. The relationship between people will be more important than today.

D. Our environment will be much more polluted with a growing number of cars.

3.The underlined word “sanguine” in the last paragraph most probably means ______.

A. disappointed　　　 B. optimistic

C. curious　　　 　　　 D. surprised

4.What does the passage mainly talk about?

A. How people will communicate in the year 2050.

B. What high technology will appear in the year 2050.

C. How people will travel and spend their holiday in the year 2050.

The Internet plays a big part in human life. We use it for work and entertainment. We can find new recipes on the Interact or advice on staying healthy. We can even use it to learn a new language. We use the Internet to keep in contact with family and friends and stay in touch with issues we care about. The list goes on and on.

Well, there may be no going back to an Internet-free life. But can using the Internet too much be bad for our health? It might be, say researchers. A new study finds that heavy Internet use may be connected to high blood pressure in an unlikely group---teenagers. So, try to be a responsible guardian for your children.

The study results show that teens who spend at least 14 hours a week online are more likely to have high blood pressure. High blood pressure makes your heart and blood vessels work too hard. Over time, this extra strain increases your risk of a heart attack or stroke. High blood pressure can also cause heart, kidney and brain diseases.

The Henry Ford Hospital in Detroit, Michigan did the study. It involved 335 young people, from 14 to 17 years old. One hundred and thirty-four of the teens were described as “heavy Internet users”. Researchers found that out of these 134 teens, 26 had high blood pressure. The researchers say the study is the first one to connect heavy web use with high blood pressure. Another research has connected that heavy Internet use with health problems including anxiety, depression and obesity.

The lead researcher of the study is Andrea Cassidy-Bushrow. For the purpose of the study, she explains, teens considered heavy Internet users were online on average “25 hours a week”. In a statement she said, “Using the Internet is part of our daily but it shouldn’t consume us.”

Ms. Gassidy-Bushrow adds that it is important for teens to take regular breaks from their computers or smart phones and to do some kinds of physical activities. She also suggests that parents limit their children’s use of the Internet to two hours a day, five days a week.

1.The author mainly wants to tell us 　　　　 .

A. how to prevent high blood pressure.

B. too much Internet use may be bad for teenagers.

C. it’s necessary for teenagers to avoid the Internet.

D. heavy Internet use will worsen teenagers’ memory.

2.What does the underlined sentence in Paragraph 5 mean?

A. People shouldn’t buy goods through the Internet.

B. People shouldn’t waste too much time on the Internet.

C. People shouldn’t fall in love with the Internet.

D. People should control the time length of using the Internet

3.According to Casssidy-Bushrow, teenagers’ use of the Internet should be limited to 　　　　 .

A. 25 hours a week　　 B. fourteen hours a week

C. ten hours a week　　 D. five hours a week

4.The text is mainly intended for 　　　　 .

A. parents　　 B. teachers

C. web-designers　　 D. students

Friends play an important role in our lives, and although we can’t be more familiar with the fact of friendship, we often don’t clearly understand how we make friends, especially with Americans. Here are some pieces of advice on making friends with Americans:

　1. Visiting places Americans enjoy: parties, churches, restaurants, parks and sports clubs.

　2. Be willing to take the first step. Don’t wait for them to get close to you. Americans in China may not know you speak English. They may be uncomfortable if they can’t speak your language.

3. Use small talks to open the conversation. Ask them where they’re from, why they come to China, etc. . Remember: Be careful not to ask personal questions about age, salary and so on.

　4. Show an interest in their culture, their country or their job. Americans like to talk about themselves!

　5. Invite them to join you for dinner or just for coffee or tea. Try to set a specific(明确的)time. Americans sometimes make general invitations like “Let’s go out for dinner sometime. ”Often this is just a way to be friendly. It is not always a real invitation.

　6. Don’t expect too much at first. Maybe they’re being friendly. But maybe they want to be your good friends. It will take time to tell.

1.According to the text, Americans like to visit the following places except＿＿＿＿.

2.What should you say when meeting an American for the first time?

3.What is mainly discussed in the text?

4.Which is the best way to make friends with an American?

Want to know how to be a confident friend-finder? We can help, with four easy steps.

Step 1. Change your mental state.

It’s easy to get so freaked out（不安的）about being in a new situation that you start throwing off don't-come-near-me signals. And guess what? It worked.1.Instead, change your attitude with some positive thinking. Tell yourself: “It’ll be great to get to know someone new”, or “I can’t wait to hear what these girls have to say.”

Step 2. Remember, the eyes have it.

The first place we look at when we’re uncomfortable is the floor. No one can tell if we’re embarrassed. We can’t tell if anyone is looking at us. Whoa!2.Holding your head up and making eye contact is a bold（大胆的）move．It’s confident and friendly.

Step 3.3.

Does starting a communication bring on an attack of shyness? Try adding a good question to your friend-finding tools. Strong opening questions usually begin with “what” or “how” words that get people talking. Typically, our first instinct (本能) is to ask a “can” or a “do” question, like “Can I borrow a pencil?” or “ Do you know where the bathroom is?4.Asking “what” or “how” questions gets you more information to respond to. Try something like “Hi. I really like that flower. How did you draw it?” or “Hi. I’m new. What’s the least scary lunch option in the cafeteria?”

Step 4. Practice, practice, practice.

Making new friends is a skill. 5.But the more you practice, the more relaxed and natural. You’ll feel, and the easier it will get. So flash that smile, offer some welcoming words, and soon you’ll be hanging out with your newest friends!

A. People don’t come near you.

B. All you need is one question.

C. Listen closely to their answers.

D. Not a good way to meet people.

E. The thought of meeting people makes you excited.

F. But that only gets you short answers. Like “Yeah”or “Down the hall”.

G. Like art, music, or sports, it takes practice to feel truly confident of it.
