Last night’s meteor(流星)shower left many people in the community dissatisfied and demanding answers.According to Gabe Rothschild,Emerald Valley’s mayor,people gathered in the suburbs of the city,carrying heavy telescopes,expecting to watch the brightly burning meteors passing through the sky.What they found instead was a sky so brightened by the city’s lights that it darkened the light of the meteors passing overhead.

“My family was so frustrated,”admitted town resident Duane Cosby.“We wanted to make this an unforgettable family outing,but it turned out to be a huge disappointment.”

Astronomers—scientists who study stars and planets—have been complaining about this problem for decades.They say that light pollution prevents them from seeing objects in the sky that they could see quite easily in the past.They call on people and the government to take measures to fight against it.

There is yet a population besides professional and amateur star observers that suffers even more from light pollution.This population consists of birds,bats,frogs,snakes,etc.For example,outdoor lighting severely affects migrating birds.According to the International Dark-Sky Association.“100 million birds a year throughout North America die in crashes with lighted buildings and towers.”

Countless more animal casualties(伤亡)result from the use of artificial lighting.Clearly,people enjoy the benefits of lighting their evenings,but some scientists think it can be harmful for humans,too.They worry that exposure to light while sleeping can increase a person’s chances of getting cancer.

Emerald Valley is only one community that is becoming aware of the negative effects of light pollution.For years,Flagstaff,Arizona,has enforced lighting regulations in its city in order to assist astronomers at the Lowell Observatory.Similar efforts have been made worldwide,and a movement is underway to remind us to turn off lights when we are not using them,so that other creatures can share the night.

1.It happened last night that

A.the city’s lights affected the meteor watching

B.the meteors flew past before being noticed

C.the city light show attracted many people

D.the meteor watching ended up a social outing

2.What do the astronomers complain about?

A.Meteor showers occur less often than before.

B.Their observation equipment is in poor repair.

C.Light pollution has remained unsolved for years.

D.Their eyesight is falling due to artificial lighting.

3.What is the author concerned about according to Paragraph 4?

A.Birds may take other migration paths.

B.Animals’ living habits may change suddenly.

C.Varieties of animals will become sharply reduced.

D.Animals’ survival is threatened by outdoor lighting.

4.What message does the author most want to give us?

A.Saving wildlife is saving ourselves.

B.Great efforts should be made to save energy.

C.Human activities should be environmentally friendly.

D.New equipment should be introduced for space study.

阅读下列短文,从每题所给的四个选项(A、B、C和D)中,选出最佳选项。

Chinese female scientist Tu Youyou won the 2015 Nobel Prize in medicine on October 5 for her discoveries concerning a novel treatment against Malaria(疟疾). This is the first Nobel Prize given to a Chinese scientist for work carried out within China.

Tu shared the prize with Irish-born William Campbell and Satoshi Omura of Japan, who were honored for their revolutionary anti-roundworm treatment. 84-year-old Tu is awarded this prize for her contribution to cutting the death rate of malaria, reducing patients’ suffering and promoting mankind’s health. Although she received several medical awards in the past, the 2015 Nobel Prize is definitely the most privilege reward that recognizes Tu’s dedication and perseverance in discovering artemisinin(青蒿素), the key drug that battles malaria-friendly parasites(寄生虫).

However, her route to the honor has been anything but traditional. She won the Nobel Prize for medicine, but she doesn’t have a medical degree or a Phd.In China, she is even being called the “three-noes” winner: no medical degree, no doctorate, and she’s never worked overseas. No wonder her success has stirred China’s national pride and helped promote confidence of native Chinese scientists.

The fact that Tu has none of these three backgrounds reminds us that science should be more accessible to all. One shall be able to become a scientist no matter what kind of background he or she comes from, as long as one dives into scientific research. There have been discussions on people who really love science but are never able to achieve much during their whole life. Their contributions can never be ignored.They work so hard to prove the wrong way so that the future researchers will be closer to the right one.

As the first Chinese mainland Nobel Prize Winner of natural science award, Tu’s record-breaking winning also serves as a reminder to those who are too eager for instant success. Science is never about instant success. Tu spent decades on scientific research before its value is officially acknowledged.There is no way to measure how much one devotes to science and compare it with how much reward he or she may get.

1.It can be concluded from the text that __________.

A. Tu worked home and abroad to conduct her research

B. Tu got the Nobel Prize for her anti-roundworm treatment

C. The Nobel Prize is the first award to recognize her work

D. Her discovery of artemisinin has helped to cut Malaria death rate

2.The author seems to agree that a person who is more likely to become a scientist is the one with__________.

A. a sense of national pride

B. relevant academic knowledge

C. a desire to achieve success

D. enthusiasm for scientific research

3.In writing the passage, the author intends to ___________.

A. inform readers of the news and make comments

B. discourage the pursuit of instant success in science

C. remind readers of the principles of scientific research

D. praise the award winner and encourage scientific research
