The problem of robocalls (自动语言电话） has gotten so bad that many people now refuse to pick up calls from numbers they don't know. By next year, half of the calls we receive will be scams(欺诈).We are finally waking up to the seriousness of the problem by supporting and developing a group of tools, apps and approaches intended to prevent scammers from getting through. Unfortunately, It’s too little, too late. By the time these "solutions" become widely available, scammers will have moved into cleverer means. In the near future, it's not just going to be number you see on your screen that will be in doubt. Soon you will also question whether the voice you're hearing is actually real.
That's because there are a number of powerful voice processing and automation technologies that are about to become widely available for anyone to use. At this year's I/O Conference, a company showed a new voice technology able to produce such a persuasive human-sounding voice that it was able to speak to a receptionist and book a reservation without being found.
These developments are likely to make our current problems with robocalls much worse. The reason why robocalls are a headache has less to do with amount than accurateness. A decade of data violation of personal information has led to a solution where scammers can easily learn your mother's name, and far more. Armed with this knowledge, they're able to carry out individually targeted campaigns to cheat people. This means, for example, that a scammer could call you from what looks to be a familiar number and talk to you using a voice that sounds exactly like your bank teller's, tricking you into "confirming" your address, mother's name, and card number. Scammers follow money, so companies will be the worst hit. A lot of business is still done over the phone, and much of it is based on trust and existing relationships. Voice processing technologies may weaken that gradually.
We need to deal with the insecure nature of our telecom networks. Phone consumers need to work together to find ways of determining and communicating what is real. That might mean either developing a uniform way to mark videos and images, showing when and who they were made by, or abandoning phone calls altogether and moving towards data-based communications-using apps like FaceTime or WhatsApp, which can be lied to your identity.
Reliability is hard to earn but easy to lose, and the problem is only going harder from now on.
1.How does the author feel about the solutions to the problem of robocalls?

The most common problem that worries all of us today is the fear of insecurity. Life has become so competitive that every now and then we are struck (遭遇) by the fear of the unknown. With every new turn of events our self-confidence takes a blow. The biggest challenge before every person today is not to lose confidence in one’s ability.
There are several reasons that affect a person’s self-confidence. The most important reason is lack of success. Not being able to succeed affects one’s self-confidence greatly. This is when one begins to doubt his own ability. In many cases one’s self-confidence is low when he feels rejected by society. For example, a person who loses his job gives a wide berth to other people for fear of being questioned about his work. However, this isn’t right at all. One needs to think along positive lines in spite of failures. After all it is your life and you have every right to live your life as you wish.
The challenge lies in not allowing your self-confidence to decrease. It is very important to believe in yourself. Self belief is the secret to success. When success doesn’t come to you, you should not allow your self-belief to be affected. Always keep in mind that success is sure to come in time. So, there is nothing wrong with your ability. Whenever lack of success causes you to doubt your ability, don’t forget to remind yourself that quick success does not last long. Also remember not to compare yourself to others. These tips will do a world of good to your confidence.
In order to be self-confident, you need to have a lifestyle that is right for you. Create one and live a life as you want to. Leave others to themselves.

It is only during the last few years that man has generally realized that in the world of nature a balance exists between all forms of life. No living thing can exist by itself. It is part of a system in which all forms of life are joined together. If we change one part of the nature order, this will almost certainly bring about changes in some other parts.
The cutting of forests reduced the supply of oxygen. The killing of weeds and insects by chemicals led to the wide-spread poisoning of animals and birds. The throwing of waste products into the ocean hurt life in the sea, while waste gases changed the chemical balance of the atmosphere and shut out some of the sun’s necessary life-giving rays.
And so we could go on adding more examples until in despair(绝望) we might feel like giving up the struggle to control these harmful human activities. Man is very clever at changing the world around him to satisfy his immediate needs, but he is not so clever at looking far ahead, or at thinking about what the future results of his action might be. Man may well destroy himself because of his silly action.

| D．no living thing can live naturally |
2.In the second paragraph the examples given are used to prove that _____.
| A．all forms of life belong to a system in which all the parts can be changed for one another |
| B．it is only during the last few years that man has generally known the balance of nature |
| C．there are some living things which can exist by themselves without change |
| D．we can’t change one form of life without destroying the balance of nature |

It is only during the last few years that man has generally realized that in the world of nature a balance exists between all forms of life. No living thing can exist by itself: it is a part of a system (体系) in which all forms of life are joined together.

The wheel was one of man’s first inventions and yet it has also proved one of the most useful. So wide and varied are the uses of the wheels, in machines and vehicles of all kinds, that it is difficult to imagine what the world would be like without them. It is surprising to hear it said, therefore, that the wheel’s importance will perhaps be greatly reduced by the end of the century by an invention so new as to be still unnamed.
The invention is a machine the floats above any surface on a cushion of air. The cushion is formed when air is blown into this saucer, the machine rises to a height that may vary from a few inches to a few feet.
Industry is already using one form of the inversion to deal with heavy loads. It can lift them. with ease and since there are no wheels, and therefore no friction , they can be put into motion with the touch of a finger.
The new invention, however , is having a great effect on transport, Not only does it make expensive road systems unnecessary, but it enables vehicles to travel well over land or water. This unique to reach most destinations has given rise to the prediction that wheeled vehicles may be uncommon at the end the century as aeroplanes were at the beginning.

Oh my God, the robots are taking over! We’re doomed! Doomed! Now that I’ve gotten that out of my system, it’s become clear that while we may or may not be doomed, the robots are taking over. The latest example is the government’s new guidelines for self-driving cars.
Tesla, Google and Uber are already testing driverless cars in cities across America. Uber chief executive Travis Kalanick is among those predicting that by 2021, self-driving cars will play a big part in urban settings.
Nearly 40,000 people died last year in this nation in automobile-related accidents, and we believe driverless cars can save tens of thousands of lives annually.
It makes sense. Robot drivers are less likely to get drunk, drive without a license, text while driving or feel agitated at the scene of a traffic jam. On the other hand, I wonder how these highly sensitive cars will react with walkers constantly dashing into the street. Will they jam on the brakes every 10 seconds?
But there’s a bigger picture. Not only are robots replacing humans behind the wheel, but behind the work desk, in warehouses, senior homes, you name it. Robots aren’t just taking over in the workplace.
The question is, where can’t a robot function better than a human? How about writing songs? A robot can go through every combination of notes in record time and come up with a pleasing melody. The lyrics might be a different story. Is a Grammy-winning song co-written by Hank Human and R-3071 in our future?
Finally, it’s only a matter of time until we have robot politicians and presidential candidates. Why not? They can be programmed to be experts in world and domestic affairs and come up with the best solutions without corruption and bad humors.
Actually, it’s too bad such technology isn’t available in 2018. Pretty sure the robot would win in a landslide.
1.What does the underlined word “agitated” in Paragraph 4 mean?
A. Exhausted. B. Embarrassed.
C. Disappointed. D. Anxious.
2.What doubt does the writer have about self-driving cars?
A. How passengers behave in it.
B. How robot drivers get the license.
C. How they respond to walkers on a busy street.
D. How they avoid crashing into other cars.
3.The last question asked in Paragraph 6 reflects the writer’s .
A. eagerness to listen to songs written by robots
B. doubt about robots’ ability to write songs
C. confidence in robots’ winning Grammy Awards
D. curiosity about the future Grammy songs
4.What might be the most suitable title for the text?
A. Robots will control the world in every field.
B. Robots can drive cars and write music.
C. Robots are being used in our daily life.
D. Robots are coming but not soon enough.
