The hand, the eyes, and the brain work together to make human beings different from other animals. No other animals have all three parts to work together. No animals can do what human beings can do. Humans can do many things and feel many things with the hand. The hand can hold onto things and make things because the thumb(大拇指) works with the fingers. This fifth finger is strong. Most animals don’t have thumbs. The thumb can press against the other fingers. Without a thumb to press against the fingers, it is difficult to hold onto anything. The thumb and fingers can also fit the flat surface of a box and the curved (不平的) surface of a pencil. We can feel that something is hot or cold, soft or hard, smooth or rough. The hand, with thumb and fingers, is one of the best tools we have. Most animals see a flat picture. Their eyes can only see how high and how wide something is. Some animals see a different picture with each eye. Some don’t see in colour. Humans see one picture with both eyes working together. We can see how high and how wide something is. We can also see how far in front of or in back of something a thing is. The brain tells other parts of the body how to work. Some of the things the body does are automatic; that is, we don’t have to think about them. For example, we don’t have to think to make our heart beat or our stomach work. The brain tells the eyes and hands how to make useful and beautiful things. That is how human beings become tool makers and artists. That is how human can have richer and better lives than other animals.

1.Human beings are different from other animals because ___________.

A. human beings have the hands, the eyes, and the brain working all the time

B. other animals also have hands, the eyes, and the brain

B. you have it in your arms and keep it there by putting your fingers firmly round it

C. you feel it with your hands

D. you press the fingers of your right hand against those of your left hand

Nuclear radiation（核辐射）has a certain mystery, partly because it cannot be detected（探测） by human senses. It can’t be seen or heard, or touched or tasted, even though it may be all around us. There are other things like that. For example, radio waves are all around but we can’t detect them or sense them without a radio receiver. Similarly, we can’t sense radioactivity without a radiation detector. But unlike common radio waves, nuclear radiation is not harmless to human beings and other living things.

At very high levels, radiation can kill an animal or human being outright by killing masses of cells in important organs. Even the lowest levels can do serious damage. There is no level of radiation that is completely safe. If the radiation does not hit anything important, the damage may not be serious. This is the case when only a few cells are hit, and when they are killed outright. Your body will replace the dead cells with healthy ones. But if the few cells are only damaged, and if they reproduce themselves, you may be in trouble. They reproduce themselves in an unusual way. They can grow into cancer. Sometimes this does not show up for many years.

This is another reason for some of the mystery about nuclear radiation. Serious damage can be done without the knowledge of the person at the time that damage has occurred. A person can be irradiated（放射治疗）and feel fine, then die of cancer five, ten, or twenty years later as a result. A child can be born weak or easy to get serious illness as a result of radiation absorbed by its grandparents.

1.According to the passage, the danger of nuclear power lies in __________.

2.Radiation can lead to serious trouble even at the lowest level __________.

3.Radiation can hurt us so much that it can ___________.

4.Which of the following can be best inferred from the passage?

5.What would be the best title of the text?

It is generally believed that humans can’t live without sleep. As any person suffering from lack of sleep knows, dark circles under the eyes usually stand out after a bad night’s sleep.

But why do people get these dark eye bags? The answer is both genetic (that is, relating to your DNA) and environmental (a result of your everyday living, such as rubbing your eyes or getting too little sleep), said Dr. Carol Clinton, a skin-care researcher in Dublin, Ohio.

But “the biggest reason is genes,” Clinton told Live Science. Eye bags are generally more noticeable in people who, because of genes, have thin or pale skin. When people are tired or very nervous, blood circulation in the eye area becomes slow, allowing blood to pool there, Clinton said. Capillaries（毛细血管）stand out, leading to dark eye circles, she said.

Besides, eye bags result from eyes’ fat moving forward. An age-connected increase in fat beneath the eyeballs leads to eye bags. “Anyway, when your eyes’ fat is moving forward, you may think about having an operation in that area,” Clinton said, “A person can get 9 hours of sleep a night, but still have eye bags because of a genetic development.”

In other cases, environmental problems cause eye bags. For example, allergies（过敏）—especially seasonal allergies—can cause capillaries to stand out. Getting too much sun can also damage and thin the skin, making dark circles under the eyes easy to see. Besides, eating salty foods can cause the body to hold more water, which makes eye bags worse, according to the Mayo Clinic.

1.In Clinton’s opinion, what is the main cause of the formation of dark eye bags?

A. Genes.　　 B. Habits.

C. Age.　　 D. The environment.

2.What can remove your eye bags according to the text?

A. Getting much sun.

B. Drinking plenty of water.

C. Having an operation on the fat in the eye area.

D. Slowing your blood circulation in the eye area.

3.What can we learn from the text?

A. It’s possible to change genes.

B. Rubbing your eyes might cause dark eye bags.

C. People with thick skin don’t get dark eye bags.

D. You can’t get dark eye bags if you get enough sleep.

4.What’s the best title for the text?

A. What Can You Do to Protect Your Eyes?

B. The Importance of Sleep to People’s Health

C. Several Measures to Remove Your Eye Bags

D. Why Do People Get “Bags” Under Their Eyes?

高一英语单项填空简单题查看答案及解析

From driving to landing on moon, more and more human tasks are being taken over by artificial intelligence(AI-人工智能). It will make everyday tasks easier and bring benefits to different industries.

And yet, like any other technology, AI will also bring risks and dangers. When people mention that AI could be dangerous, they think of the situation in films where an AI program decides to kill or enslave all humans. While this possibility is unlikely for now, there are many other dangers that AI could bring to mankind.

In February 2018, a group of AI experts got together to discuss the possible misuse of AI. What they found was that “Every AI advance by the good guys is an advance for the bad guys, too”. Their main worry was that criminals could use AI for many bad purposes, including using AI to create websites that could steal people’s personal information. Another possible risk was faster hacking(黑客)—AI programs could be taught to find weaknesses in software and break into computer systems. Some other risks were as dramatic as the ones we see in books and movies. For example, long-distant attacks could be made easier through the use of AI. And, finally, there were some worries on imitating voices as well. It is possible that AI could be used to make false photos and videos. In china, tech giant Baidu has developed a program called Deep Voice that can “clone” anyone’s voice by studying a 3.7-second audio sample (声音样本).

Many people in the tech world have expressed worry about AI. People like US businessmen Bill Gates and Elon Musk have called for the industry to be more strictly controlled, as there are few laws currently governing the use of AI. Famous British Physicist Stephen Hawking even thought AI could finally cause the end of mankind. “Once humans develop artificial intelligence, it will take off and redesign itself at an alarming rate. Humans…couldn’t compete and would be replaced.”

1.What cannot possibly be done by AI right now?

A.Driving cars. B.Landing on moon.

C.Playing games. D.Ruling all humans.

2.Which saying has a similar meaning with the underlined sentence in Paragraph 3?

A.Every coin has two sides. B.Prevention is better than cure.

C.Risk nothing, gain nothing. D.One’s meat is another’s poison.

3.How many misuses of AI are mentioned in Paragraph 3?

A.One. B.Two.

C.Three. D.Four.

4.Why does the author mention Stephen Hawking’s words?

A.To show Hawking’s perfect prediction.

B.To strengthen the high position of Hawking.

C.To help readers understand the serious situation.

D.To introduce the famous scientist--Stephen Hawking.

5.What does the whole passage mainly talk about?

A.Risks and dangers of AI. B.Guidance of AI usage.

C.Advantages and disadvantages of AI. D.Development of AI industry.
