Have you ever imagined what human beings will look like in the future? Well, now you don’t have to.

According to AsapScience, a Canada-based video channel that touches on many different science topics, humans will be very different creatures 1,000 years from now.

Artificial intelligence, genetic engineering and climate change will work together to change our bodies greatly, according to a video recently published by the channel.

We could, for instance, develop red eyes as our DNA changes, and have darker skin because of global warming.

The video painted a picture of a future world in which our bodies are part human, part machine. Nanobots, or tiny robots, will be put into our bodies, improving our abilities.

“No longer will we be limited by our own physiology. We will truly become a mixture of biology and machine on the inside,” says the video.

Meanwhile, designer babies will cause future generations to grow into intelligent, attractive people. As global warming takes hold, humans will also be skinnier and taller, as this body shape deals with heat better.

In fact, Cadell Last, a researcher at the Global Brain Institute located in Belgium, believes change may happen even faster than this.

As he said in a paper recently published in Current Aging Science, mankind is already going through a major evolutionary change. In less than four decades, Last claims, we will live longer, have children in old age and need artificial intelligence to finish daily tasks.

“Your 80 or 100 is going to be so radically different than your grandparents,” Last said. Instead of living fast and dying young, he believes humans will live slow and die old.

“The biological clock isn’t going to be around forever,” he added, and said that people could pause it for some time using future technology.

Just a few hundred years ago, most humans were working in the fields, while nowadays more and more are getting an education. These are just predictions, and no one can be sure how human beings will evolve in the future. But with such large changes in our environments, it seems likely that we will all look very different one day.

1.Which of the following factors could play a role in the appearance of future humans, according to the text?

A. Advanced technology and global warming.

B. Medicine that fights aging and genetic engineering.

C. The Internet and artificial intelligence.

D. The cold weather and the dangers of machines.

2.The video released by AsapScience said that .

A. humans will be thinner and shorter

B. future humans’ bodies will be part machine

C. humans will develop red eyes that will enable them to see clearly at night

D. tiny robots will be put in humans’ minds and will give them super abilities

3.Which of the following would Cadell Last probably agree with?

A. Future babies will be designed according to their grandparents’ wishes.

B. Our increasing dependence on artificial intelligence will threaten our survival one day.

C. Future technology will pause our biological clocks so that humans live slower and longer.

D. In less than four decades, humans will have a sudden genetic change that will make us rely on artificial intelligence.

4.The main purpose of the article is to .

A. tell us about a prediction of how humans will look in the future

B. offer us different theories on how humans will evolve in the future

C. encourage us to be imaginative about how humans will look in the future

D. inform us what kinds of factors Could influence how humans will look in the future

Our house was directly across the street from the clinic entrance of John Hopkins Hospital in Baltimore. We lived downstairs and rented the upstairs rooms to the patients at the clinic.

One evening as I was fixing supper, there was a knock at the door. I opened it to see a truly awful-looking man. He’s hardly taller than my eight-year-old son. “Good evening. I’ve come to see if you’ve a room. I came for a treatment this morning from the eastern shore, and there’s no bus till morning.” He told me he’d been hunting for a room since noon but with no success. “I guess it’s my face…I know it looks terrible, but my doctor says with a few more treatments…” For a moment I hesitated, but his next words convinced me: “I could sleep in this chair on the porch. My bus leaves early in the morning.”

I told him we would find him a bed. When I had finished the dishes, I talked with him. He told me he fished for a living to support his five children, and his wife, who was hopelessly crippled (殘疾的) from a back injury. He didn’t tell it by way of complaint. Next morning, just before he left, as if asking a great favor, he said, “Could I come back and stay the next time?” He added, “Your children made me feel at home.”

On his next trip he arrived a little after seven in the morning. As a gift, he brought a big fish and the largest oysters (牡蠣) I had ever seen. I knew his bus left at 4:00 a.m. and I wondered what time he had to get up in order to do this for us.

In the years he came to stay overnight with us and there was never a time that he did not bring us vegetables from his garden. I know our family always will be grateful to have known him; from him we learned how to accept the bad without complaint when facing the misfortune.

1.Why did the author agree to let the man spend the night in his house at last?

A. Because the man said others refused to accommodate him.

B. Because the man said he would not cause much inconvenience.

C. Because the man said he had come from the eastern shore.

D. Because the man said he had been hunting for a room since noon.

2.How long would it take the man to travel from his home to Baltimore by bus?

A. About 1 hour. B. About 2 hours.

C. About 3 hours. D. About 4 hours.

3.From the text we can know that __________.

A. the author’s children were kind and friendly to the man

B. the man was fed up with his hard-work and his family

C. John Hopkins Hospital provided rooms for the patients to live in

D. the author and his family were thought highly of by his neighbors

4.The author’s family were grateful to know the man because __________.

A. he often brought them fish and vegetables from his garden

B. he paid them money for his staying

C. he taught them how to accept the bad without complaint

Pronunciation Tips

These English pronunciation tips will help you get the most out of your Pronunciation Power program.

★ 1.

For example, “threw” and “through”, although spelled differently, are pronounced the same. Also, identical（相同的） letters or letter clusters（字母組合） in words do not always produce the same sound. For example, the “ough” in “though” and “through” represents a different sound in each word. 2.

★ Imagine a sound in your mind before you say it.

Try to visualize（想象)）the positioning of your mouth and face. 3.

★ Listen to and try to imitate the Pronunciation Power instructor.

In addition to listening for specific sounds, pay attention to pauses, the intonation（語調(diào)） of the instructor's voice and patterns of emphasis. 4.

★ The English language has many different dialects, and words can be pronounced differently.

It is important, however, that you pronounce words clearly to ensure effective communication.

★ Finally, the Pronunciation Power program is a tool to help you.

But you must practice what you are learning! Remember that you are teaching your mouth a new way to move. You are building muscles that you do not use in your own language. 5. Use the program to exercise your mouth a little bit each day.

A. Read these words over and over again and try to learn them by heart.

B. This can be just as important as the pronunciation of sounds.

C. Learn to practice what you hear, not what you see.

D. So you should force yourself to do what you really don’t like to do.

E. Do not confuse pronunciation of words with their spelling!

F. It is like going to the gym and exercising your body.

G. Think about how you are going to make the sound.

Exercise seems to be good for the human brain，with many recent studies suggesting that regular exercise improves memory and thinking skills．But an interesting new study asks whether the apparent cognitive benefits from exercise are real or just a placebo effect — that is，if we think we will be “smarter” after exercise，do our brains respond accordingly？The answer has significant implications for any of us hoping to use exercise to keep our minds sharp throughout our lives．

While many studies suggest that exercise may have cognitive benefits，recently some scientists have begun to question whether the apparently beneficial effects of exercise on thinking might be a placebo effect．So researchers at Florida State University in Tallahassee and the University of Illinois at Urbana Champaign decided to focus on expectations，on what people anticipate that exercise will do for thinking．If people’s expectations jibe (吻合) closely with the actual benefits，then at least some of those improvements are probably a result of the placebo effect and not of exercise．

For the new study，which was published last month in PLOS One，the researchers recruited 171 people through an online survey system，they asked half of these volunteers to estimate by how much a stretching and toning regimens (拉伸運動) performed three times a week might improve various measures of thinking．The other volunteers were asked the same questions，but about a regular walking program．

In actual experiments，stretching and toning program generally have little if any impact on people’s cognitive skills．Walking，on the other hand，seems to substantially improve thinking ability．

But the survey respondents believed the opposite，estimating that the stretching and toning program would be more beneficial for the mind than walking．The estimates of benefits from walking were lower．

These data，while they do not involve any actual exercise，are good news for people who do exercise．“The results from our study suggest that the benefits of aerobic exercise are not a placebo effect,” said Cary Stothart，a graduate student in cognitive psychology at Florida State University，who led the study．

If expectations had been driving the improvements in cognition seen in studies after exercise，Mr．Stothart said，then people should have expected walking to be more beneficial for thinking than stretching．They didn’t，implying that the changes in the brain and thinking after exercise are physiologically genuine．

The findings are strong enough to suggest that exercise really does change the brain and may，in the process，improve thinking，Mr．Stothart said． That conclusion should encourage scientists to look even more closely into how，at a molecular level，exercise remodels the human brain，he said． It also should encourage the rest of us to move，since the benefits are，it seems，not imaginary，even if they are in our head．

1.Which of the following about the placebo effect is TRUE according to the passage？

A． It occurs during exercise．

B． It has cognitive benefits．

C． It is just a mental reaction．

D． It is a physiological response．

2.Why did the researchers at the two universities conduct the research？

A． To discover the placebo effect in the exercise．

B． To prove the previous studies have a big drawback．

C． To test whether exercise can really improve cognition．

D． To encourage more scientists to get involved in the research．

3.What can we know about the research Cary Stothart and his team carried out？

A． They employed 171 people to take part in the actual exercise．

B． The result of the research removed the recent doubt of some scientists．

C． The participants thought walking had a greater impact on thinking ability．

D． Their conclusion drives scientists to do research on the placebo effect．

4.What might be the best title for the passage？

A． Is it necessary for us to take exercise？

B． How should people exercise properly？

C． What makes us smarter during exercise？

D． Does exercise really make us smarter？
