Although nuclear power may lead to disasters, ______ the nuclear power industry has been operating safely for three decades in China.

A. and B. but C. so D. yet

D

【解析】

試題分析：考查連詞的辨析。A并且，B但是，C所以，因此，D然而，但是。由題中的although（盡管），我們可以推斷出該句為讓步狀語(yǔ)從句，后面表達(dá)的是但是的意思，然而although和but不能同時(shí)出現(xiàn)在一個(gè)句子中，所以選yet，句意為：盡管核能也許會(huì)帶來(lái)災(zāi)難，但是核能產(chǎn)業(yè)已經(jīng)在中國(guó)安全運(yùn)行了三十年了。故選D。

考點(diǎn)：考查連詞的辨析。

If you need glasses to read this, you are among the majority of Chinese students. That’s because most students in China are short-sighted which means they can only see things close up and distant things will be blurry. Four-fifths of high school students wear glasses and now more and more children in primary school need glasses, too.

This epidemic of poor eyesight has two very simple causes: too much time spent indoors studying and too little time spent outdoors playing. Reading and writing for hours and hours, sometimes in poorly lighted rooms, causes eyesight to weaken. But students have to do this because there is so much pressure on them to succeed in school. And because they spend so much time indoors at school and at home, they have less time to spend outdoors enjoying the sun.

The sun, as a consequence, is important in developing good eyesight. Exposure to daylight releases a chemical in the eyes that prevents, or at least delays, short-sightedness. According to a study by Ian Morgan of Australian National University, Australian children and Chinese children have the same level of eyesight before they start school, but once they enter primary school, Chinese children only spend about an hour a day outside, while Australian children spend three to four hours each day in the sunshine. The result is that while about 40 percent of Chinese primary school students need glasses, only three percent of Australian children do.

Wearing glasses may not seem like a big deal. For some, wearing glasses can even be an opportunity to make a fashion statement. But poor eyesight at a young age can have serious long term consequences. As you get older, your eyesight can worsen and lead to things like macular degeneration(黃斑變性), a condition of the eyes for which there is no cure and which can eventually lead to blindness.

With all that in mind, don’t you think it’s time to give your eyes a break? Try spending a little less time inside and go for a walk in the park, instead. It’s the healthy thing to do and your eyes will thank you for it.

1.What does the underlined word “blurry” mean?

A. unpopular. B. unpleasant.

C. unclear. D. unconscious.

2.How should the students protect their eyesight according to the passage?

A. They should study less and less.

B. They should stay longer outdoors.

C. They should wear sun-glasses.

D. They should have a longer rest in bed.

3.It can be inferred from the passage that __________ is to blame for the poor eyesight of Chinese children.

A. the ever-worsening bad weather

B. the ever-increasing burden of study

C. the ever-decreasing sunny days

D. the ever-decreasing period of study time

4.What is the purpose of this article?

A. To explain why Chinese students are poor-sighted.

B. To admire Australian children’s good eyesight.

C. To criticize the present education system.

D. To call on people to protect Chinese children’s eyesight

Doctors sometimes use light therapy to treat a form of depression in people who get too little morning sun. But too much light at other times may actually cause such mood disorder. Long-lasting exposure to light at night brings depression, a new study finds, at least in animals.

The new data confirm observations from studies of people who work night shifts, says Richard Stevens of the University of Connecticut Health Center. Mood disorders join a growing list of problems, including cancer, obesity and diabetes that can occur when light throws life out of balance by disturbing the biological clock and its timing of daily rhythms.

In the new study, Tracy Bedrosian and Randy Nelson of Ohio State University exposed mice to normal light and dark cycles for four weeks. For the next four weeks, half of the mice remained on this schedule, and the rest received continuous dim light throughout their night. Compared with mice exposed to normal night-time darkness, those getting dim light at night lost their strong preference for sweet drinks. “A sign that they no longer get pleasure out of activities they once enjoyed,” Bedrosian says.

In a second test, mice were clocked on how long they actively tried to escape a pool of water. Those exposed to night lights stopped struggling and just floated in the water, a sign of “behavioral despair”, 10 times as long as the mice that had experienced normal night-time darkness. All symptoms of depression disappeared within two weeks of the mice returning to a normal light-dark cycle, the researchers report. The scientists could also quash the behavioral symptoms by injecting the brains of animals with a drug that prohibits the activity of certain molecules linked with human depression. This finding further suggests that light at night may cause something related to depression.

Human studies linking night-time light and mood disorders are important but can not easily detect molecular underpinnings(分子基礎(chǔ)) as animal studies can, says George Brainard of Thomas Jefferson University. The new work, he says, suggests that the change of the biological clock by light at night can be “an extremely powerful force in regulating biology and behavior”.

1.After being exposed to continuous night-time light, the mice __________.

A. changed their preferences

B. escaped from the water more eagerly

C. remained active as before

D. showed less interest in their favorites

2.What does the underlined word “quash” in paragraph 4 probably mean?

A. study B. predict

C. ease D. cause

3.We can learn from the last paragraph that _______________.

A. light at night may have practical value

B. the biological clock is beneficial to humans

C. human mood disorders cannot be healed easily

D. human studies are more important than animal studies

4.What is the main idea of the passage?

A. Night-time light may cause depression.

B. A drug has been found to cure mood disorders.

C. The study on animals can be applied to humans.

D. Human biological clock can be controlled by light.
