Over the past few months huge groups of locusts(蝗虫), one of which occupied an area more than three times the size of New York City, have eaten up crops across the Home of Africa and the Middle East, leaving an estimated 20 million people at risk of famine(饥荒). The first generation's eggs are starting to hatch, and now even bigger swarms(虫群) are forming threatening. Countries from the Democratic Republic of Congo to Yemen, Iran, Pakistan and India, “representing a threat to food security and livelihoods,” says the U.N.'s Food and Agriculture Organization(FAO).
Desert locusts' populations explode when weather conditions are right. That explosion can create huge swarms that can travel great distance-more than 90 miles in a day-in search of food. Warm weather and unusually heavy rains in the Horn of Africa at the end of 2019 provided the moist(湿润的) soil necessary for hatching eggs. From there, the insects spread rapidly, resulting in one of the worst outbreaks the region has seen in more than 70 years.
A typical swarm numbering 4 billion to 8 billion locusts, can consume in one day the same amount of food as 35 million people. Some swarms have been so thick in parts of Kenya that they have prevented planes from taking off. Governments have used widespread aerial spraying of pesticides when available; in poorer regions, where aircraft are unavailable, soldiers battle the swarms with handheld spray pump.
The FAO has appealed for $138 million to support affected communities, If the locusts are not stopped before the next generation hatches, the impact could be terrible: the FAO guesses that an additional 25 million people across the region could lose their crops. Scientists in Kenya hope a new computer-assisted tracking program that combines satellite data with weather-mapping software will help predict the swarms next destination, buying-regional authorities enough time to prepare a response. Buy coronavirus- related travel restriction have delayed relief efforts as well as response mechanisms. The locusts have no such travel limitations.

高三英语单项填空简单题查看答案及解析
Around the world, honeybee groups are dying in huge numbers: About one-third of nests collapse each year. For bees and the plants they pollinate (授粉) — as well as for beekeepers, farmers, honey lovers and everyone else who appreciates this marvelous social insect — this is a catastrophe.
Honeybee collapse has been particularly worrying because there is no one cause, but rather a thousand little cuts. The main elements include the mixed impact of pesticides (杀虫剂) applied to fields, as well as pesticides applied directly into nets to control bugs, pests and diseases; nutritional shortages caused by vast acreages of single-crop fields that lack diverse flowering plants; and commercial beekeeping itself, which destroys groups by moving most bees around the country multiple times each year to pollinate crops.
The real issue, though, is not the volume of problems, but the interactions among them. Here we find a major lesson from the bees that we ignore at our risk: the concept of synergy (协同作用), where one plus one equals three, or four, or more. A typical honeybee colony contains remains from more than 120 pesticides. Alone, each represents a benign dose (良性剂量). But together they form a poisonous soup of chemicals whose interplay (相互作用) can greatly reduce the effectiveness of bees’ immune systems, making them easier to suffer from diseases.
Observing the death of honeybees should warn us that our own well-being might be similarly threatened, and the widespread collapse of so many groups presents a clear message: We must demand that our regulatory authorities require studies on how exposure to low dosages of combined chemicals may affect human health before approving compounds.
Bees also provide some clues to how we may build a more collaborative relationship with the services that ecosystems can provide. Bees could offer some of the pollination service needed for agriculture. People discovered that crop harvests, and thus profits, are maximized if some cropland are left uncultivated for bees. Meanwhile a variety of wild plants means a healthier, more diverse bee population, which will then move to the planted fields next door in larger and more active numbers.
1.Which of the following is NOT the cause that leads to bees dying?
A. Lack of nutrition from enough diverse flowering plants.
B. The pests and diseases of the bees.
C. The beekeepers’ destroying without intention
D. The pesticides applied to crops.
2.By saying “one plus one equals three, or four, or more” in Paragraph 3, the author means that ____.
A. bees united mean they are much more powerful
B. bees united mean they are much more poisonous
C. pesticides mixed mean they are much more poisonous.
D. pesticides mixed mean they are much more effective.
3.The lesson people can learn from bees dying is that ____________.
A. medicine is as powerful as pesticide
B. our health might be threatened by pesticides
C. we should protect bees by reducing the usage of pesticides
D. medicine may be harmful to us when used together
4.What is the last paragraph mainly about?
A. Keeping a balance with nature is important
B. More plants mean more and healthier bees.
C. Bees are very important to agriculture.
D. Bees can bring in good higher profits to farmers

高三英语单项填空中等难度题查看答案及解析
Hi, everybody. Over the past couple months, most of the political headlines you’ve read have probably been about the government shutdown and the launch of the Affordable Care Act. And I know that many of you have rightly never been more frustrated with Washington.
But if you look beyond those headlines, there are some good things happening in our economy. And that’s been my top priority since the day I walked into the Oval Office.
After decades in which the middle class was working harder and harder just to keep up, and a punishing recession that made it worse, we made the tough choices required not just to recover from crisis, but to rebuild on a new foundation for stronger, more durable economic growth.
Five years later, we have fought our way back. Our businesses have created 7.8 million new jobs in the past 44 months. Another 200,000 Americans went back to work last month.
The American auto industry has come roaring back with more than 350,000 new jobs – jobs churning out and selling the high-tech, fuel-efficient cars the world wants to buy. And they’re leading the charge in a manufacturing sector that has added jobs for the first time since the 1990s – a big reason why our businesses sell more goods and services “Made in America” than ever before.
We decided to reverse our addiction to foreign oil. And today, we generate more renewable energy than ever, more natural gas than anybody, and for the first time in nearly 20 years, America now produces more oil than we buy from other countries.
We decided to fix a broken health care system. And even though the rollout of the marketplace where you can buy affordable plans has been rough, so far, about 500,000 Americans are poised to gain health coverage starting January 1st. And by the way, health care costs are growing at the slowest rate in 50 years.
And one more thing: since I took office, we’ve cut our deficits by more than half. And that makes it easier to invest in the things that create jobs – education, research, and infrastructure.
Imagine how much farther along we could be if both parties were working together. Think about what we could do if a reckless few didn’t hold the economy hostage every few months, or waste time on dozens of votes to repeal the Affordable Care Act rather than try to help us fix it.
In the weeks ahead, I’ll keep talking about my plan to build a better bargain for the middle class. Good jobs. A good education. A chance to buy a home, save, and retire. And yes, the financial security of affordable health care. And I’ll look for any willing partners who want to help.
Because of your hard work and tough sacrifices over the past five years, we’re pointed in the right direction. But we’ve got more work to do to keep moving that way. And as long as I’m President, I’ll keep doing everything I can to create jobs, grow the economy, and make sure that everyone who works hard has a chance to get ahead. Thanks, and have a great weekend.
1.Which of the following is not the reason for people’s frustration with the government?
A. The government shut down
B. Unemployment rate
C. The addiction to foreign oil
D. The launch of the Affordable Care Act
2.Why does the president mention more goods and services “Made in America”?
A. To show that American goods and services are very popular.
B. To indicate that American people should be dependent on themselves.
C. To show that the employment rate has been increased.
D. To show that American auto industry enjoys high technology.
3.What’s the meaning of the underlined word “repeal”?
A. To abolish B. To protect
C. To strengthen D. To weaken
4.According to the speech, which of the following can be implied?
A. American people have every reason to feel frustrated with the government.
B. Health care costs are growing at the slowest rate in 50 years.
C. The president feels sorry that the economy is not moving in the right direction.
D. Some government officials don’t agree with the president on the medical care system.

There has been a dramatic increase in the number of natural disasters over the past few years, and it is assumed that global warming and climate change could cause even more disasters in the future. Some of the world’s leading cities are facing disasters like floods and heat waves.
London
London’s flood defences are getting older. Since 1982, the Thames Barrier(水闸)has protected the city from the threat of flooding, but it was only designed to last until 2030 and close once every two or three years. About 26 years later the barrier now closes five or six times a year and according to Environment Agency predictions, by 2050 the barrier will be closed on almost every tide if the problem is not addressed.
There are 26 underground stations, 400 schools, 16 hospitals, an airport and 80 billion worth of property in London’s flood risk area, so large scale flooding would be disastrous.
Paris
Over a six week period in July and August 2003, more than 1 1,400—mainly elderly people—died in France from dehydration(脱水)and extremely high body temperature in a deadly heat wave. Heat waves of similar intensity(强度)are expected every seven years by 2050, so what can be done to make sure such a disaster does not happen again?
One solution is to have air-conditioners installed in elderly care homes. But this is considered a short-term solution, as the increase in demand for electricity also increases carbon emissions(排放).
In Paris the local authorities are encouraging architects to design new types of buildings such as the building “Flower Tower,” which uses a covering of bamboo to act as a natural air-conditioner.
Shanghai
Shanghai is the fastest growing city on Earth. It has a population of 18 million and is only 4 meters above sea level. Sea levels are predicted to rise by 20 cm within the next century.
An estimated 250,000 people move to Shanghai every year in search of work, placing extra demands on energy consumption. China relies heavily on coal—fired power stations, but these emissions increase temperatures and, in turn, warmer seas increase the risk of typhoons.
1.What problem should be settled now in London?
A.How to protect the city’s property
B.Where to build its flood defences
C.How to use the Thames Barrier to protect the city
D.How to improve the function of the old flood defences
2.Which of the following measures can’t solve the heat wave disaster in Paris?
A.Putting up new types of buildings with a covering of bamboo
B.Having air-conditioners installed in elderly care homes
C.Forbidding the city to build“Flower Tower”
D.Encouraging architects to design new types of buildings
3.The major threats to Shanghai are .
A.increasing population and coal-fired power stations
B.rising sea levels and typhoons
C.extremely high temperature and rising sea levels
D.extra demands on energy consumption and typhoons
4.The purpose of the passage is .
A.to tell us how to protect the big cities
B.to give advice on how to defend natural disasters
C.to explain what causes flood and heat waves
D.to warn us of the increasing natural disasters in big cities
5.Which of the following would be the best title for the passage?
A.Big Cities Facing Big Disasters
B.Big Disasters in the Future
C.The Increase of Natural Disasters
D.Solutions to Natural Disasters
