The Internet and the World Web (网) are great places to be right now. We use the word "place" because so many of the things you can do online are similar to the things you can do wherever people gather together-in homes , schools , libraries , shopping centers , or at family reunions(团聚)or town meetings. The Net allows people to learn shop, find important information, and communicate, whether they're local, global or simply virtual (虚的) .

The Web is useful. You can find old friends online. You can research and book flights, check the weather, find breaking news, find out information about schools and colleges. You can even place an order for books, CDs, computers and cars.

The Internet is also fun. You can write to old friends or check out their web pages, enjoy web - based soap operas, laugh at online jokes, join in a live Net Event, chat with other Internet surfers(漫游者) , check to see if your name appears anywhere on the Web .

Millions of users log on to the Net every day, and it's not just to do research. There's a lot of fun there. That's one reason why it's called web "surfing".

Of course, the first step to using the Web for business or for fun is learning how to work a "web browser"(浏览器). If you're new to computers, it may take a while before you are completely comfortable with your browser. Don't worry. You don't have to be a computer  whiz(专家). The basics of a web browser are very much like the basics of modem computers

—learning how to point and click the mouse, learning how to scroll(滚动) up and down a page of text, and learning how to use pull - down menus. Again, be patient. There's no time limit on web surfing . Give yourself a chance to explore (探索) the browser itself while you explore the Web.

1.The writer compares the Web to ______.

A. places to visit B. places to gather together in

C. some easy job D. things you can do online

2.We can learn from the text that the Web is not only ______ but also

A. of great use; of great value B. of great use; of great enjoyment

C. useful; funny D. of some use; of a little interest

3.To use the Web, all we have to do is to learn how to_______ .

A. use the computer mouse B. scroll up and down a page of text

Much meaning can be conveyed, clearly, with our eyes, so it is often said that eyes can speak.

Do you have such kind of experience? In a bus you may look at a stranger, but not too long. And if he is sensing that he is being stared at, he may feel uncomfortable.

The same in daily life. If you are looked at for more than necessary, you will look at yourself up and down, to see if there is anything wrong with you. If nothing goes wrong, you will feel angry toward others’ stare at you that way. Eyes do speak, right?

Looking too long at someone may seem to be rude and aggressive. But things are different when it comes to stare at the opposite sex. If a man glances at a woman for more than 10 seconds and refuses to move his gaze, his intentions are obvious, that is, he wishes to attract her attention, to make her understand that he is admiring her.

However, the normal eye contact for two people engaged in conversation is that the speaker will only look at the listener from time to time, in order to make sure that the listener does pay attention to what the former is speaking, to tell him that he is attentive.

If a speaker looks at you continuously when speaking, as if he tries to dominate you, you will feel uncomfortable. A poor liar usually exposes himself by looking too long at the victim, since he believes in the false idea that to look straight in the eye is a sign of honest communication. Quite the contrary.

In fact, continuous eye contact is confined to lovers only, who will enjoy looking at each other tenderly for a long time, to show affection that words cannot express.

Evidently, eye contact should be done according to the relationship between two people and the specific situation.

1.Which of the following behaviors is proper according to the passage?

A. To the opposite sex, stare at him or her.

B. To a stranger, avoid looking at him or her.

C. In a conversation, look at the listener all the time.

D. Make eye contact depending on the relationship and different situations.

2.If two persons exchange eye contact gently for long, what is probably their relationship?

A. Boss and employee. B. Lovers.

C. Teacher and student. D. Strangers

3.What’s the best title of the passage?

A. Don’t stare at others B. Body language is important

C. Eyes can speak D. Eye contact benefits you

In 2017, AlphaGo defeated Chinese player Ke Jie to become the world’s No 1, ending thousands of years of human dominance(控制)in the game. AlphaGo is an artificial intelligence(AI)Go-playing program.1.

Artificial intelligence(AI)is usually defined as the science of marking computers do things that require intelligence when done by humans.2.These include learning, reasoning, problem-solving, perception, and language-understanding.

3.In fact we are increasingly depending. upon computer-based artificial intelligence. As Charlie Qrtiz said, head of AL at the Massachusetts-based software company Nuance Communication, “It has opened a window for us.”Smartphones, self-driving cars, intelligent robots,etc. are constantly coming into our life. According to a recent survey, half of the world’s AI experts believe human level machine intelligence will be achieved by 2040. This will open up huge possibilities for the enrichment of mankind, from tackling climate change and treating disease to labour- saving devices.

4.Physicist Stephen Hawking last year warned that unless we take care, board games might be the least of it. “The development of full artificial intelligence could mean the end of the human race.”5.They believe AlphaGo’s victory is a reminder of how fast the world is overcoming the obstacles in the way of AI, and its distribution in the world about us. Although there may yet be no evidence that computers will ever shake off their human masters, we should still treat these development with the humility and caution they deserve.

A. Other scientists have also expressed the concern.

B. Artificial intelligence has both advantages and disadvantages.

C. Defeating a human Go master is not the only thing AI can do.

D. Artificial intelligence will bring us disasters instead of benefits.

E. It was designed by an American Artificial intelligence company.

F. Not all experts hold the optimistic attitudes to the development of AI.

G. Research in AI has so far focused on some special fields of intelligence.

When a leafy plant is under attack, it doesn’t sit quietly. Back in 1983,two scientists,Jack Schultz and Ian Baldwin, reported that young maple trees getting bitten by insects send out a particular smell that neighboring plants can get. These chemicals come from the injured parts of the plant and seem to be an alarm.What the plants pump through the air is a mixture of chemicals known as volatile organic compounds,VOCs for short.

Scientists have found that all kinds of plants give out VOCs when being attacked .It’s a plant’s way of crying out.But is anyone listening?Apparently.Because we can watch the neighbours react.

Some plants pump out smelly chemicals to keep insects away.But others do double duty .They pump out perfumes designed to attract different insects who are natural enemies to the attackers.Once they arrive,the tables are turned .The attacker who was lunching now becomes lunch.

In study after study,it appears that these chemical conversations help the neighbors .The damage is usually more serious on the first plant,but the neighbors ,relatively speaking ,stay safer because they heard the alarm and knew what to do.

Does this mean that plants talk to each other? Scientists don’t know. Maybe the first plant just made a cry of pain or was sending a message to its own branches, and so, in effect, was talking to itself. Perhaps the neighbors just happened to “overhear” the cry. So information was exchanged, but it wasn’t a true, intentional back and forth.

Charles Darwin, over 150 years ago, imagined a world far busier, noisier and more intimate(亲密的) than the world we can see and hear. Our senses are weak. There’s a whole lot going on.

1.What does a plant do when it is under attack?

A. It makes noises. B. It gets help from other plants.

C. It stands quietly D. It sends out certain chemicals.

2.What does the author mean by “the tables are turned” in paragraph 3?

3.Scientists find from their studies that plants can .

A.predict natural disasters B.protect themselves against insects

C.talk to one another intentionally D.help their neighbors when necessary

4.what can we infer from the last paragraph?

A.The word is changing faster than ever.

B.People have stronger senses than before

C.The world is more complex than it seems

D.People in Darwin’s time were more imaginative.
