高二英语单项填空中等难度题查看答案及解析

The entire global population of marbled crayfish (龙纹虾) has been traced to a single female held in a German aquarium (水族馆), which was born with the ability to reproduce without males. Every marbled crayfish is female, and every egg laid is an exact clone of its mother. The ability to reproduce quickly with such ease made them popular in the aquarium trade, but when they found their way into the wild, the crayfish got out of control.

The first known marbled crayfish appeared in 1995. Since then, they have spread into the wild and populated in freshwater ecosystems around the world. Scientists studying this animal have raised the alarm about its likely influence on local wildlife, ecosystems and agriculture as it spreads into new environments. Successful non-native species like the marbled crayfish often cause trouble when they arrive in new environments, as they can feed on local wildlife or compete with it for resources.

According to Dr Frank Lyko, a researcher at the German Cancer Research Centre, the first marbled crayfish appeared due to a sudden change in its parents’ cells. It was an animal that reproduces clonally and therefore represents a model of a central aspect in tumor (肿瘤) development.

“Tumor genomes (基因组) also develop clonally, because they go back to a single original cell,” he said. However, both crayfish and tumors are still able to adapt to their environments through a process termed “clonal evolution”, and in both cases this can be harmful. In crayfish, their ability to adapt means they can spread to a variety of different environments and climates, and in tumors this means they can develop resistance (抵抗) against cancer-targeting drugs.

At present, with the potential influence of the increasing marbled crayfish on local places, governments from different places are working on controlling their population.

1.What does the text say about marbled crayfish in the wild?

A.They prove popular. B.They are under control.

C.They can be troublesome. D.They are out of condition.

2.What does Dr Frank Lyko try to explain?

A.The reason for marbled crayfish’s clonal reproduction.

B.The similarities between marbled crayfish and tumors.

C.The way to stop marbled crayfish cloning themselves.

D.The harmful influence marbled crayfish have on health.

3.What are governments doing about marbled crayfish now?

A.Working on removing all of them. B.Trying to limit the quantity of them.

C.Taking control of them with drugs. D.Connecting them with harmful tumors.

4.What can be a suitable title for the text?

A.Why Marbled Crayfish Reproduce Rapidly

B.The Population of Marbled Crayfish Is Huge

C.The Spread of Marbled Crayfish Is Worrying

D.How to Control the Number of Marbled Crayfish

This day marks the rising of a new food startup, the first company to be financed entirely by the crowd, and of it every business thus relies on thousands of customers to grow. Lisa, 25, its main founder and CEO, believes it will be a path that will become increasingly popular, and ultimately will produce more thriving（繁荣的）businesses from the scratch.

“In the food industry, no venture capital (VC, 风险投资) will even look at you until you’ve hit a million in sales. As a fresh hand in business, unless you’re independently wealthy, you will likely need to raise some money before then,” Lisa complained. So few businesses approached VC firms at the beginning. It was no exception with her. Thus, she turned to a new financing tool at hand, crowdfunding, to raise money from the crowd who’d like to take a bet on her company.

But for a company, it didn’t make sense to seek investments when all they had was an idea and a few months of consumer testing data. The food market is extremely competitive. No investor would put money behind a totally unproven new super food product founded by a bunch of twenty-somethings. “But we had a story. And crowds love stories.” Lisa said delightedly. So she put together an online crowdfunding campaign, explaining how she began working with this amazingly nutritious plant in the Peace Corps and then started selling it in the U.S. to support the poor in the West Africa.

On the online platform where they were to raise the money, a friend convinced them to change their goal from $20,000 to $50,000. Lisa stayed up all night worrying they wouldn’t hit it. But they reached $24,000 in 24 hours and ended their funding with $53,000. Seeing the number, Lisa said, “Thank you! To my crowd and for your belief!”

1.Why couldn’t Lisa get investments in a traditional way?

A. She lacked confidence in business.

B. Her food company was in poor condition.

C. VC demanded too much in choosing partners.

D. Consumers were not satisfied with her new products.

2.According to the passage, crowdfunding ________.

A. ensures the investors a good return

B. aims to help badly managed companies

C. attracts more people to become investors

D. helps startups deal with money shortages

3.The underlined word “twenty-somethings” refers to ________.

A. twenty impractical ideas　　 B. young people over twenty

C. twenty inexperienced partners　　 D. a company with twenty branches

4.Which of the following best explains Lisa’s success?

A. Great minds think alike.　　 B. Honesty is the best policy.

C. Many hands make light work.　　 D. A friend in need is a friend indeed.

While sweet treats can be hard to resist, the World Health Organization(WHO) has set new guidelines for people around the world. The guidelines, released on Wednesday, advise that both adults and children cut back on their sugar intake(摄取量) to stay healthy.

In a statement, Francesco Branca, director of the WHO’s nutrition department, said there is evidence that reducing daily sugar intake reduces the risk of being overweight and tooth decay(腐烂).

The guidelines do not apply to the sugars in fresh fruit and vegetables or those that are naturally present in milk. According to the WHO, there is no reported evidence of negative effects of consuming those sugars. Instead, the new guidelines focus on “added” or “free” sugars. These include sugars that are added to processed foods and drinks such as candy and soft drinks.

Added sugars are sometimes described as “ hidden” sugars because they exist in foods we might not think of as sweets, such as honey and ketchup(番茄酱). Health experts advise that consumers look at ingredients on food packages to help make better-informed decisions.

The WHO recommends that people in the United States, Europe and other Western societies should cut their average sugar intake by about two-thirds, or down to just 10% of their overall calories. For developing countries, where dental care is less advanced, the WHO recommends that sugar intake be reduced to 5%.

Scientist Kieran Clarke, of the University of Oxford, notes that for those people who can’t shake their love for sweets, getting more exercise is a good solution. “If you get enough exercise, you can eat almost anything,” she said “But it’s very hard to avoid large amounts of sugar unless all you’re eating is fruit and vegetables.”

1.What can we learn from the guidelines released by the World Health Organization?

A. The production of candies should be forbidden.

B. There is a connection between sugar intake and bad teeth.

C. Fruit and vegetables contain a lot of sugar.

D. People should cut down on sugar intake for the sake of their health.

2.To what level should people in developing countries cut down their sugar intake, according to the WHO?

A. 10%.            B. 15%.            C. 5%.            D. 30%.

3.We can learn from the text that ________.

A. added sugar isn’t marked on food packages

B. we should drink as little milk as possible as it contains sugar

C. soft drinks don’t contain added sugar

D. the less exercise you do, the fewer sweet things you should eat
