More than 40 percent of the species that help with pollination (植物传粉) are under threat due to the polluted environment. So some researchers have been searching for ways to protect the bees and other crucial pollinators while some engineers have thought perhaps an army of robotic pollinators could keep humans well-supplied in these foods. A team of researchers has recently designed a small drone capable of pollinating flowers. They tested their device on the large, pink flowers of lilies. And it worked.

Exciting as this success was, it is only the first step. The team has yet to figure out how to apply the concept on the massive scale. Could a fleet of robo-pollinators replace the bees?

“Although the answer isn’t a straightforward no, it would be a challenging leap to go from this one little drone pollinating one large flower to an army of drones spreading across fields of crops,” says Scott Swinton, an agricultural economist at Michigan State University.

“The successful pollination was fascinating,” Scott Swinton says, “but the device itself might damage the flowers. I wonder how you make sure you’re not doing more harm than good to flowers when you have a drone.”

“Furthermore,” he points out, “a lily is a particularly easy flower for a drone to pollinate. To make this more broadly applicable for smaller and more complex flower structures, the drones would need to be particularly agile.”

Still, Joshua Campbell, an expert at the University of Florida, says “Pollination systems are extremely complex and will always require insects. There is no substitute for bees.”

“As for the technology itself, it is a promising new development in existing drone technology,” he added. Yet he still sees some hurdles ahead before drones can be applied on a large scale.

1.What makes those scientists invent pollinating drones?

A. There are no satisfying pollinators.

B. Humans need more food supplies.

C. Pollinating species are being endangered.

D. Drone technology is well-developed now.

2.What problem does Scott think scientists have to solve for the robo-pollinators?

A. Making them look like bees. B. Using them in quantity.

C. Keeping them flying non-stop. D. Instructing them to tell plants.

3.The underlined word “agile” in Para 6 can be replaced by “________”.

A. cheap B. catchy

C. lovely D. smart

4.What’s the best title for the passage?

A. Will pollinating drones take over for honeybees?

B. What is leading pollinating honeybees to decline?

C. Why does pollinating need a money-saving option?

D. How did researchers invent pollinating drones?

More than half of UK species have suffered declines in recent years and 15 percent are at risk of vanishing (消失), a report has warned. There is little evidence to suggest the rate of loss is slowing down.

Farming is key to what is happening,with more intensive agriculture affecting nearly half of the species studied and responsible for nearly a quarter of the total impact on wildlife. A loss of mixed farms, changes to sowing patterns,increased use of pesticides and fertilizers and a loss of habitat (栖息地）have taken their toll. The report said government farming policies had led to dramatic changes in farming practices,almost doubling wheat and milk yields since the 1970s, but often at the expense of nature by interrupting the food sources and habitats species rely on.

Climate change is also increasingly affecting UK nature although the impacts are mixed with some species spreading north or surviving better in warmer winters, but others are hit by the loss of coastal habitat, increased sea temperature and wilder weather. In the long term, global warming poses one of the greatest threats to nature around the world. Wildlife is also being hit by urban development, loss of town green areas, changes to the way land and forests are managed and over-abstraction (过度抽取)of water.

“The natural world needs our help as never before,” said naturalist and TV presenter David Attenborough. “We must work together, governments, conservationists, businesses and individuals to help it.”

The good news is that the creation of new wetland by conservation programs and the planting of new woodland, as well as wildlife-friendly farming programs, are providing habitats for struggling species. Reintroduction of species such as the pine marten (松貂)and large blue butterflies is also helping, but more needs to be done, the report said.

1.What does the underlined phrase “taken their toll” in Paragraph 2 mean?

A.Cost much money. B.Had bad effects.

C.Changed farming policies. D.Interrupted the food sources.

2.What is the main cause of UK species decrease?

A.The development of agriculture.

B.The over-use of water.

C.The change of climate.

D.The loss of habitats.

3.What does the author intend to tell us in the last sentence?

A.More large blue butterflies are needed in UK.

B.More should be done for the diversity of species.

C.The report sounds the alarm for the UK’s wildlife.

D.Enough measures have been taken to protect the natural world.

4.Where is this text most likely from?

A.A poster. B.A brochure.

C.A magazine. D.A notice.

The case for college has been accepted without question for more than a generation. A school graduates ought to go, says conventional wisdom and statistical evidence, because college will help them earn more money, become “better” people, and learn to be more responsible citizens than　 those who don't go.

But college has never been able to work its magic for everyone. And now that close to half our high school graduates are attending, those who don't fit the pattern are becoming more numerous, and more obvious. College graduates are selling shoes and driving taxis; college students interfere with each other's experiments and write false letters of recommendation in the intense competition for admission to graduate school. Other find no stimulation in their studies, and drop out-often encouraged by college administrators.

Some observers say the fault is with the young people themselves-they are spoiled and they are expecting too much. But that is a condemnation of the students as a whole, and doesn't explain all campus unhappiness. Others blame the state of the world, and they are partly right. We have　 been told that young people have to go to college because our economy can't absorb an army of untrained eighteen-year-olds. But disappointed graduates are learning that it can no longer absorb　 an army of trained twenty-two-year-olds, either.

Some adventuresome educators and watchers have openly begun to suggest that college may not be the best, the proper, the only place for every young person after the completion of high school. We may have been looking at all those surveys and statistics upside down, it seems, and through the rosy glow of our own remembered college experiences. Perhaps college doesn't make people intelligent, ambitious, happy, liberal, or quick to learn things-may it is just the other way around, and intelligent, ambitious, happy, liberal, quick-learning people are merely the ones who have been attracted to college in the first place. And perhaps all those successful college graduates would have been successful whether they had gone to college or not. This is heresy (离经叛道的想法 ) to those of us who have been brought up to believe that if a little schooling is good, more has to be much better.

But contrary evidence is beginning to mount up.

1.According to the author, ________.

A.people used to question the value of college education

B.people used to have full confidence in higher education

C.all high school graduates went to college

D.very few high school graduates chose to go to college

2.In the 2nd paragraph, "those who don't fit the pattern" refer to ________.

A.high school graduates who aren't suitable for college education.

B.college graduates who are selling shoes and driving taxis.

C.college students who aren't any better for their higher education

D.high school graduates who failed to be admitted to college.

3.According to the passage, the problems of college education partly originate in the fact that ________.

A.society cannot provide enough jobs for properly trained graduates.

B.high school graduates do not fit the pattern of college education.

C.too many students have to earn their own living.

D.college administrators encourage students to drop out.

4.In this passage the author argues that ________.

A.more and more evidence shows college education may not be the best thing for high school graduates

B.college education is not enough if one wants to be successful

C.college education benefits only the intelligent, ambitious, and quick-learning people

D.intelligent people may learn quicker if they don't go to college
