【题目】Which of the following sentences is right?

A.He’s lent away the book for two weeks.

B.I have been the army since two days ago.

C.His father has left here since he was born.

D.I haven’t seen him for ages.

【答案】D

【解析】

句意:下面哪个句子是对的?

考查短暂性动词与延续性动词的转换。He’s lent away the book for two weeks. 他把这本书借给别人两个星期了。句中的时间是for two weeks,所以动词应该用延续性动词,所以A选项是错误的;I have been the army since two days ago. 我自从两天前就开始当兵了。句中的时间是since two days ago,所以动词要用延续性动词,而由句意可知,这里指的是“参加”,英语是join,其延续性动词是be in/ be a member of,所以这里been后面少了in;所以B选项是错误的;His father has left here since he was born. 他父亲从出生起就离开了这里。由句意可知,主句中的动作是要持续一段时间的,所以应该用延续性动词,leave的延续性动词是be away,所以C选项错误;I haven’t seen him for ages. 我好久没见到他了。本句中动词本身就是延续性动词,所以不需要转换,故选D

【题目】 What is the future of AI(人工智能)? Will it be a good thing? We asked four students what they think.

TinaI believe AI will be more useful in our future lives. It's now used in many fields, like phones and medicine. No one really knows what will happen if machines become smarter than humans. However, I'm sure AI will help us solve many problems.

BillI am worried that people create something that can be better than themselves. In the near future, AI will develop at a high speed. Humans may be replaced because AI robots will do lots of human jobs.

MaryI really think that AI will change the way we work, the way we live. And the way we think. Imagine if we could put a CPU inside our brain! Soon we'll be able to improve our math and memory. How exciting!

JohnThink of what's happening right now. Some robots are used to kill animals under human orders. The media often gives the impression that human-level AI of the sort we see in sci-fi movies is just around the corner, uncomfortably close. I think the killing-decision thing should not be given to the machine. Otherwise, Al will be very dangerous for humans. We need to be careful about what we ask machines to do.

【题目】 Sometimes our body does things we don't ask it to do. Sneezing(打喷嚏),coughing, blinking(眨眼睛)and even yawning(打哈欠)are examples of involuntary movements or reflex actions(反射动作). What makes our body do these things?

These involuntary actions are a response(反应)to a stimulus(刺激). When we do these things, our body is trying to protect itself. If an irritant(刺激物)such as pollen(花粉)from plants gets into our nose or nasal passages(鼻腔通道),our body sneezes to get it out. If we breathe in dust, our body coughs to remove it from our lungs()or windpipe. We blink in order to keep our eyes clean and moist(湿润)and to prevent dust and other things from staying on them. A yawn is our body's way of making us put more oxygen into our bloodstream.

. These involuntary movements happen because our brain is giving out signals. There is a system of nerves(神经)called the central nervous system, that covers our entire body: from the brain, down the spinal cord(脊髓)inside our spinal column (the bones that do down our back,to the tips of our fingers and toes. When our body parts sense certain things, like a mosquito蚊子)bite, a message is sent to our brain. Then the brain sends a message back to itch(发痒).

Without these reflex actions, we would not live very long.

1What is the passage mainly about?

A.We would not live long without movements.B.Why our body does involuntary movements.

C.We sneeze to get out an irritant such as pollen.D.How our brain is giving out signals to our nerves.

2If dust comes into our eyes, we will________ to protect our body.

A.coughB.sneezeC.blinkD.yawn

3Which of the following sentences can be put at the beginning of Paragraph 3?

A.What tells our body to take care of us the way it does?

B.Don't you think it is interesting for our body to do so?

C.What can we do when involuntary movements happen?

D.How can we avoid stimulus to protect our own body?
