Nanda sees a wearable computer as a handbag, one that’s built out of four-inch squares and triangles of fabric (织物), with tiny computer chips embedded (嵌入) in it. It looks, feels and weighs like your typical leather purse.
That’s where the similarities end: This bag can wirelessly keep track of your belongings and remind you, just as you’re about to leave the house, to take your wallet. It can review the weather report and suggest that you grab an umbrella. This purse can even upload your favorite songs onto your scarf (围巾).
Sure, a computing purse and scarf set may seem like the stuff of science fiction. But these devices (装置), part of next generation of wearable computers, could become common within a few years. DuPont created new super strong fibres that can conduct electricity and can be woven into ordinary-looking clothes. And the chipmaker developed chip packaging allowing wearable computers to be washed, even in the heavy-duty cycle.
As a result, these new wearable devices are different from the heavy and silly types of the recent past, which often required users to be wrapped in wires and type on their stomachs. Unlike the old types, these new wearable computers also make economic sense. When her bag becomes commercially available in two to three years, Nanda expects it will cost around $150, which is the price of an average leather purse.
Here’s how the bag works: You place a special radio-signal-transmitting chip onto your wallet. A similar radio in your purse picks up the signal and notifies you that you’ve forgotten to take your wallet. In turn, sensors on your purse’s handles will inform the computer that you’ve picked up the purse and are ready to go.
Already, these new kinds of wearable devices are applied in markets like auto repair, emergency services, medical monitoring-and even, increasingly, for consumers at large. Indeed, more people will want to cross that bridge in the coming years—making for a booming market for wearable computers that don’t look like something out of science fiction.
1.Which of the following describes a wearable computer?
A．It can be washed in washing machines.

A．require users to operate on the stomach
B．pick up the signals through wires and chips
C．are being put to use in some different areas now
D．are smarter but more expensive than the old ones

As one comes to some crossroads, he or she sees a sign which says that drivers have to stop when they come to the main road ahead. At other crossroads, drivers have to go slow, but they do not actually have to stop unless, of course, there is something coming along the main road; and at still others, they do not have either to stop or to go slow, because they are themselves on the main road.
Mr. Williams, who was always a very careful driver, was driving home from work one evening when he came to a crossroad. It had a “SLOW” sign. He slowed down when he came to the main road, looked both ways to see that nothing was coming, and then drove across without stopping completely.
At once he heard a police whistle, so he pulled into the side of the road and stopped. A policeman walked over to him with a notebook and a pen in his hand and said, “You didn’t stop at that crossing.”
“But the sign there doesn't say ‘STOP’.” answered Mr. Williams, “It just says ‘SLOW’, and I did go slow.”
The policeman looked around him, and a look of surprise came over his face. Then he put his notebook and pen away, scratched his head and said, “Well, I’m in the wrong street!”
1.When he was stopped by a policeman, he ____.
A. was driving at a high speed B. was driving onto the main road
C. was going to stop his car D. was pulled into the crossroad
2.Though slowly, Mr. Williams continued driving at the crossing because________ .
A. he saw a “STOP” sign in the opposite street
B. he paid no attention to the traffic rules
C. he didn't have to stop
D. he was eager to get home
3.Looking round Mr. Williams, the policeman was surprised because__________ .
A. he met a mad man
B. he realized that he himself was mistaken
C. Mr. Williams dared to speak to him like that
D. Mr. Williams would not apologize to him
4.What does “scratch” in the last paragraph mean?
A. to rub the skin of (the head) for uncertainty
B. to strike (the head ) for regret
C. to nodded for sure
D. to look back to search for something

When people see machines that respond like humans, or computers that perform amazing feats of strategy, they sometimes joke about a future in which humanity will need to accept robot overlords. But buried in the joke is a seed of unease. Science fiction writing and popular movies have shown us about artificial intelligence (AI) that exceeds the expectations of its creators and escapes their control, eventually outcompeting and enslaving humans or targeting them for extinction(灭绝).
Even in the real word, not everyone is ready to welcome AI with open arms. In recent years, as computer scientists have pushed the boundaries of what AI can accomplish, leading figures in technology and science have warmed about the frightening dangers that artificial intelligence may pose to humanity, even suggesting that AI capabilities could destroy the human race.
But why are people so frightened about the idea of AI?
Elon Musk is one of the famous voices that have raised red flags about AI, In July 2017. Musk told attendees at a meeting of the National Governors Association, I have exposured to the very cutting-edge Al,and I think people should be really concerned about it.I keep sounding the alarm bell. But until people see robots going down the street killing people, they don't know how to react, because it seems so impossible."
Earlier, in 2014, Musk had labeled AI "our biggest existential threat," and in August 2017, he declared that humanity faced a greater risk from AI than the terrorists. Physicist Stephen Hawking, who died on March14, also expressed concerns about AI, telling the BBC in 2014 that "the development of full artificial intelligence could spell the end of the human race.
1.What are top scientists in AI worried about?
A. Its ability of impressive fests. B. It contributes too much to movies.
C. It may end the human race some day. D. It's capability to bury our seeds in jokes.
2.What is "red flags" in paragraph 4?
A. Questions. B. Warnings
C. Complaints. D. Wonders.
3.In Stephen Hawking' opinion, AI could_____
A. be a great threat to human beings. B. learn the human emotions like fear,
C. predict the future of the human race. D. compose horrible tales into scary stories.
4.The text is probably taken from a research paper in____
A. Technology B. Health

高二英语阅读理解中等难度题查看答案及解析
There are two basic ways to see growth: one as a product, the other as a process. People have generally viewed personal growth as an external (外在的) result or a product that can easily be identified and measured．The worker who gets a rise, the student whose grades improve, the foreigner who learns a new language—all these examples of people who have measurable results to show for their efforts．
By contrast, the process of personal growth is much more difficult to determine, since it is a journey and not the specific signposts or landmarks along the way．The process is not the road itself, but the attitudes, feelings people have , and their caution or courage, as they meet with new experiences and unexpected difficulties．In this process, the journey never really ends；there are always new ways to experience the world, new ideas to try, new challenges to accept．
In order to grow, to travel new roads, people need to have a willingness to take risks, to face the unknown, and to accept the possibility that they may “fail” at first．How we see ourselves as we try a new way of being is necessary for our ability to grow．Do we see ourselves as quick and curious? If so, we tend to take more chances and be more open to unfamiliar experiences．Do we think we’re shy and indecisive? Then our sense of fear can cause us to hesitate, to move slowly, and we think we are slow to adapt change or that we’re not smart enough to deal with a new challenge．Then we are likely to take a more passive role or not try at all．
These feelings of insecurity (不安全) and self-doubt are both unavoidable and necessary if we are to change and grow．If we protect ourselves too much, then we stop growing．We become trapped inside a shell of our own making．
1.In the author’s eye, one who views personal growth as a process would ______．
A．succeed in climbing up the social ladder
B．grow up from his own achievements
C．face difficulties and take up challenges
D．aim high and reach his goal each time
2.Which of the following can be viewed as the process of personal growing?
A．Our manager was always willing to accept new challenges．
B．Jane won the first prize in the speech competition．
C．Jerry picked up French during his stay in Paris．
D．Father’s salary rose from 5, 000 to 7,000．
3.For personal growth, the author is in favor of all the following EXCEPT _______．
A．being curious about more changes
B．being quick in self-adaptation
C．having an open mind to new experiences
D．staying away from failures and challenges
4.Which of the following is NOT true according to the passage?
A．It is not so easy to measure personal growth
B．To try and fail on the new road facing the unknown is unavoidable
C．There are only two ways to see a person’s growth
D．If you are too shy to take any risks in life, you cannot grow up
