科目：高中英語 來源：205-2016學年吉林毓文中學高二下期中考試英語試卷（解析版） 題型：閱讀理解

At thirteen, I was diagnosed（診斷）with kind of attention disorder. It made school difficult for me. When everyone else in the class was focusing on tasks, I could not.

In my first literature class, Mrs. Smith asked us to read a story and then write on it, all within 45 minutes. I raised my hand right away and said, “Mrs. Smith, you see, the doctor said I have attention problems. I might not be able to do it.”

She glanced down at me through her glasses, “you are no different from your classmates, young man.”

I tried, but I didn’t finish the reading when the bell rang. I had to take it home.

In the quietness of my bedroom, the story suddenly all became clear to me. It was about a blind person, Louis Braille. He lived in a time when the blind couldn’t get much education. But Louis didn’t give up. Instead, he invented a reading system of raised dots (點), which opened up a whole new world of knowledge to the blind.

Wasn’t I the “blind” in my class, being made to learn like the “sighted” students? My thoughts spilled out and my pen started to dance. I completed the task within 40 minutes. Indeed, I was no different from others; I just needed a quieter place. If Louis could find his way out of his problems, why should I ever give up?

I didn’t expect anything when I handed in my paper to Mrs. Smith, so it was quite a surprise when it came back to me the next day with an “A” on it. At the bottom of the paper were these words: “ See what you can do when you keep trying?”

1.The author didn’t finish the reading in class because .

A．He was new to the class

D．He wanted to take the task home

2.What do we know about Louis Braille from the passage?

A．He made a great invention.

B．He had good sight.

C．He gave up reading.

D．He learned a lot from school.

3.What was Mrs. Smith’s attitude to the author at the end of the story?

A．Angry. B．Impatient.

C．Sympathetic. D．Encouraging.

4.What is the main idea of the passage?

A．The disabled should be treated with respect.

B．A teacher can open up a new world to students.

Internet use appears to cause a decline in psychological well-being（安康）, according to research at Carnegie Mellon University.

Even people who spent just a few hours a week on the Internet experienced more depression and loneliness than those who logged on less frequently, the two-year study showed. And it wasn’t that people who were already feeling bad spent more time on the Internet, but that using the Net actually appeared to cause the bad feeling.

Researchers are puzzling over the results, which were completely contrary to their expectations. They expected that the net would prove socially healthier than television, since the Net allows users to choose their information and to communicate with others.

The fact that Internet use reduces time available for family and friends may account for the drop in well-being, researchers suggested. Faceless, bodiless “virtual”（虛擬的）communication may be less psychologically satisfying than actual conversation, and the relationship formed through it may be shallower. Another possibility is that exposure to the wider world via the Net makes users less satisfied with their lives.

“But it’s important to remember this is not about the technology per se; it’s about how it is used,” says psychologist Christine Riley of Intel, one of the study’s sponsors. “It really points to the need for considering social effects in terms of how you design applications and services for technology.”

1.The best title for this passage would be ________.

A. Internet may Cause Depression

B. The Dark Side of Internet

C. How to Use Technology Properly

D. The Importance of Psychological Well-being

2.Internet use may cause a decline in psychological well-being because ________.

A. people who were already feeling bad spend more time on the Internet

B. Internet users thought the world was wider than it really was

C. people were too eager to turn the “virtual” communication into reality

D. people have less time for actual communication with their family and friends

3.What does the underlined Latin word “per se” (in Para. 5) mean?

A. probably	B. absolutely
C. oneself	D. itself

4.What’s the tone of the passage?

A. Optimistic.	B. Critical.
C. Objective.	D. Pessimistic.

Scientists are debating how to limit their newly-discovered power to change genetic structure (結構). Scientists already modify the genes (基因) of farm animals and agricultural plants to make them more productive or stronger. But now they can also change genes in wild animals and plants. These genes would continue into later generations. For example, it may be possible for scientists to remove from existence the kind of mosquitoes, small flying insects, that carry the Zika virus. They might also be able to permanently remove species (物種) of plants and animals that are damaging to other species.

In a report published last week, the U. S. National Academies of Sciences, Engineering and Medicine (NAS) said it supports continued research on this kind of gene control. But it warned that it is not possible to know what will happen when these changed plants and animals are released (釋放) into the wild.

Sixteen biologists, ethicists (倫理學家) and policymakers are on an NAS committee that is examining the issue. They say that there is value to the new technology. But, they say, there is not enough evidence to support the release of modified organisms (生物體) from the laboratory into nature.

Many people would support stopping mosquitoes and rats from carrying diseases. But scientists say we must understand the possible scientific, ethical, legal and social results of such action before we decide whether to take it. Gene modification is spread through reproduction (繁殖).

Changed genes will continue to spread as long as an animal or plant continues to reproduce. They cannot be limited to a farm or kept within a country's borders. Scientists are wondering what may happen if a modified organism mates with another species. They are not yet sure how the modified genes would affect the other species. It is possible that those genes could harm those creatures or even lead to their disappearance from our planet.

【小題１】What possible advantage does gene control in wild animals and plants have?

A. Changing the Zika virus permanently.

B. Getting rid of damaging species forever.

C. Having the changed genes in their next generations.

D. Making all the species more productive and stronger.

【小題２】As for genetically changed wild animals and plants, what are scientists worried about?

A. They may become weaker or die out.

B. They may be more productive than before.

C. They may cause damage to their living habitat.

D. Their genes may spread to later generations.

【小題３】Which of the following is true according to the passage?

A. Scientists are certain what exact results gene modification leads to.

B. Gene modification can benefit some farm animals and agricultural plants.

C. Scientists won't modify any genes before they make the final decision.

D. Gene modification will be encouraged in more creatures in the near future.

【小題４】The article is mainly intended to ________.

A. appeal against research on gene control

B. show how to change genetic structure

C. inform us of power and danger of gene control

D. give the reason why gene modification is necessary
