Listening Text
Guide: Welcome aboard, time travellers! We'll begin our tour shortly. Today's tour will take you back in time 50 years. For some of you, this tour will take you back to the days of your childhood.
[Tourists exclaim, "Amazing!" "Wow!" "I can't wait to see my great grandpa!" before quietening down.]
Guide: Before we start our tour, I have to explain the rules of time travel. Please listen carefully. Number 1, don't talk to anybody.
Tourist 1: Why not I'm going to tell my 8-year-old self to buy shares in companies that are profitable today. That way, when I get back to the present, I’ll be rich!
Guide: I'm afraid you cannot do that! If you do that, you'll change your life path. Maybe you will grow up to be a rich person. But that rich person will be a new person, not the person you are today. That person, the present "you" will disappear forever. That's what we call a paradox.
Tourist 1: So, what you're saying is that learning about the future might change the way I am forever The "me" that I am now could no longer exist !
Guide: Exactly. OK, next, be careful not to break anything. Breaking something can also cause a paradox and change your path through life.
Tourist 1: OK, I'll remember that.
Tourist 2: How about if I just give my father a present The latest model of a smartphone or something. He was just a 13-year-old boy back then. Imagine how excited he'll be!
Guide: Absolutely not! Anything that doesn't belong to that time may have an impact on someone and cause a paradox. Just think about if you change the life path of your father, maybe you'll never be born. In fact, that's what I was going to say next - you must never give anything from our time to someone in the past.
Tourist 2: What about if I just leave it lying around for my father to find That's OK, isn't it
Guide: No, that's not allowed, either!
Tourist 2: Are you serious
Guide: I certainly am! That is exactly the same as giving it yourself. I would strongly advise against interacting with anyone.
Tourist 2: Let me get this straight. You mean that we can't talk to anyone, can't break anything, or leave anything in the past
Guide: That's right.
Tourist 2: OK, got it. It'll be exciting enough to see the people in the past.
Tourist 1: I can't wait to see my great grandpa!
Guide: OK, so... [fade out]

阅读理解 (选自2019年高考英语江苏卷)
Who cares if people think wrongly that the Internet has had more important influences than the washing machine Why does it matter that people are more impressed by the most recent changes
It would not matter if these misjudgments were just a matter of people's opinions. However, they have real impacts, as they result in misguided use of scarce resources.
The fascination with the ICT (Information and Communication Technology) revolution, represented by the Internet, has made some rich countries wrongly conclude that making things is so "yesterday" that they should try to live on ideas. This belief in "post-industrial society" has led those countries to neglect (忽视) their manufacturing sector, with negative consequences for their economies.
Even more worryingly, the fascination with the Internet by people in rich countries has moved the international community to worry about the "digital divide" between the rich countries and the poor countries. This has led companies and individuals to donate money to developing countries to buy computer equipment and Internet facilities. The question, however, is whether this is what the developing countries need the most. Perhaps giving money for those less fashionable things such as digging wells, extending electricity networks and making more affordable washing machines would have improved people's lives more than giving every child a laptop computer or setting up Internet centres in rural villages. I am not saying that those things are necessarily more important, but many donators have rushed into fancy programmes without carefully assessing the relative long-term costs and benefits of alternative uses of their money.
In yet another example, a fascination with the new has led people to believe that the recent changes in the technologies of communications and transportation are so revolutionary that now we live in a "borderless world". As a result, in the last twenty years or so, many people have come to believe that whatever change is happening today is the result of great technological progress, going against which will be like trying to turn the clock back. Believing in such a world, many governments have put an end to some of the very necessary regulations on cross-border flows of capital, labour and goods, with poor results.
Understanding technological trends is very important for correctly designing economic policies, both at the national and the international levels, and for making the right career choices at the individual level. However, our fascination with the latest, and our under-valuation of what has already become common, can, and has, led us in all sorts of wrong directions.
1. What is the consequence of misjudgments on the influences of new technology
A. A waste of limited resources.
B. A conflict of public opinions.
C. A slow progress in technology.
D. A lack of confidence in technology.
2. What does the example in Paragraph 4 suggest
A. Donators should take people's essential needs into account.
B. Donators should provide more affordable Internet facilities.
C. Donators should make their programmes attractive to people.
D. Donators should ensure that each child gets financial support.
3. What has led many governments to remove necessary regulations
A. Ignoring the power of economic development.
B. Believing that the world has become borderless.
C. Overlooking the impacts of technological advances.
D. Over-emphasising the role of international communication.
4. What can we learn from the passage
A. Traditional technology still has a place nowadays.
B. Economic policies should follow technological trends.
C. People should be encouraged to make more donations.
D. Making right career choices is crucial to personal success.

Nikola Tesla Was Ahead of His Time
As a great inventor, Nikola Tesla's innovations were well ahead of his time and it was not until recent years that his futuristic visions and innovations in many modern technologies came to be understood. (1) _________________________ Here is a look at some of Tesla's most bizarre ideas that had some ties to reality.
Livestreamed Video
Tesla may have had a good grasp of what it feels like to watch real-time streaming of video on modern-day laptops and smartphones. He made the prediction based on the principles of radio as early as 1926. (2) _________________________ "We shall be able to witness the inauguration of a president, the playing of a World's Series baseball game, the havoc of an earthquake, or a battle just as though we were present," he said in the interview.
The Thought Camera
(3) _________________________ In an article published in 1933, he told reporters about several projects he had been working on, including a device that concerns "photographing of thought." He believed that any mental imagery or thought would have a corresponding retinal (视网膜的) image, which could be photographed and projected onto a viewing screen. (4) _________________________ Luckily, scientists today have created artificial retinas through complicated mathematical analyses of how real retinas convert images to electrical impulses to send up to the brain.
Wireless Electricity
Perhaps the greatest ambition of Tesla was his dream to wirelessly transmit energy across long distances, using only air as a medium. He demonstrated it was possible to wirelessly light up lamps using a method called inductive coupling, but he wasn't successful in building a long-range system to broadcast energy. Today, the areas of its exploration range from wireless charging of digital devices at home to potential power supplies for space elevators. (5) _________________________ There is a long way to go before these innovative techniques can replace existing systems and become widely used.
A. Still, there are some major barriers.
B. Everyone's thoughts could be seen on the screen.
C. It was described in an interview published in Collier's Weekly.
D. However, he never succeeded in turning this theory into reality.
E. Traces of his inventions can be found in many modern-day devices.
F. His ideas were ridiculed at his time, but some have now come to fruition.
G. Tesla may have thought about inventing a machine to read mental imagery and thoughts.
