Humans might be the most highly-evolved species on the planet, but most animals possess skills we can only dream of having. Imagine how much electricity we could save if we could see in the dark the way cats do. Imagine leaping from tree to tree like a monkey. Giraffes, which are otherwise calm and good-natured, sleep only 4.6 hours a day.

We realized a long, long time ago that nature provides the best blueprint for invention. We’ve borrowed canals from beavers and reflectors from cat’s eyes. Although the words “bionics”(仿生学) became popular only after the 1960s, history shows that nature has always provided ideas on solving everyday problems. Our archives(档案) don’t go back to the time of Leonardo da Vinci and his bird-like flying machines, but we can take you to the late 19th century, where we applied those same principles for building our first practical airplanes.

To prepare for their flight at Kitty Hawk, the Wright brothers studied the movements of pigeons to figure out how they stayed high up when they were heavier than air. Their success inspired scores of successors to improve on the airplane by studying various aspects of nature. One of Orville Wright’s pupils caught and stuffed seagulls to examine their wingspan. Meanwhile, two French inventors examined spinning sycamore(梧桐) seeds in an effort to apply those same motions, reversed, to a helicopter .

Some examples are more obvious than others. The outside of the airplane designed by the Wright brothers looks like a minimalistic(简单抽象艺术) structure. On the other hand, Barney Connett’s fish submarine actually looks like a fish.

Some bio-inspired concepts have yet to be invented. In the 1960s, the US Army commissioned several university professors to conduct research on the motor skills animals in hope of applying those same abilities to tanks. Tanks that run like horses or jump like grasshoppers(蚂蚱)-sounds shocking, doesn’t it? But imagine how life would change if we could achieve that.

1.“Cats”, “monkeys” and “giraffes” mentioned in paragraph 1 are examples to show______.

A. they are highly-evolved species as humans

B. animals have skills that humans do not possess

C. humans can learn animals’ skills

D. they are skillful in different ways

2.What happened after the Wright brothers’ success?

A. People carried out a systematic study on pigeons.

D. People kept their airplane at a French gallery.

3.Which of the following is true about the research carried out by the US Army?

A. It has cost a large sum of money.

B. It has changed our life.

C. It has improved the abilities of tanks

D. It has not succeeded yet.

4.What does the writer want to tell in the passage?

A. many inventions get ideas from nature.

B. Some animals possess unique skills.

C. People should protect nature.

D. Bionics is far from perfect

 

A new study has found that it may be possible to train people to be more intelligent, increasing the brainpower they had at birth．

Until now，it has been widely assumed that the kind of mental ability that allows us to solve new problems without having any relevant previous experience—what psychologists call fluid intelligence—is innate and cannot be taught（though people can raise their grades on tests of it by practicing）．

But in the new study，researchers describe a method for improving this skill，along with experiments to prove it works．

The key, researchers found, was carefully structured training in working memory—the kind that allows memorization of a telephone number just long enough to dial it．This type of memory is closely related to fluid intelligence，so the researchers reasoned that improving it might lead to improvements in fluid intelligence．

First they measured fluid intelligence of volunteers using standard tests．Then they trained each in a complicated memory task—the child’s card game，in which they had to recall a card they saw and heard．During the course, they needed to ignore irrelevant items, monitor ongoing performance，manage two tasks at the same time and connect related items to one another in space and time．

The four groups experienced a half-hour of training daily for 8, 12, 17 and 19 days, respectively．To make sure they were not just improving their test-taking skills，the researchers compared them with control groups that took the tests without the training．

The results, published Monday in The Proceedings of the National Academy of Sciences，were striking．Improvement in the trained groups was a lot greater．Moreover，the longer they trained, the higher their scores were．All performers，from the weakest to the strongest，showed significant improvement．

“Our results show you can increase your intelligence with proper training．” said Dr Jaeggi, a co-author of the paper．“No one knows how long the gains will last after training stops,” he added, “and the experiment’s design did not allow the researchers to determine whether more training would continue to produce further gains．

1.By writing the article，the writer intends to ______________．

A. inform the readers of a new study

B. call on people to be trained to increase intelligence

C. prove one’s born brainpower can be improved

D. tell people the improved intelligence will last forever

2.The researchers thought the key to improving the intelligence was ______________．

A. memorizing telephone numbers

B .improving working memory

C. training in concentration

D. recalling a card

3.The following aspects of the training help increase intelligence EXCEPT___________．

A. ignoring irrelevant items

B.monitoring ongoing performance

C.managing two tasks at the same time

D.using previous experience

4.When the experiment was conducted, the researchers______________．

A.trained the four groups for the same period of time

B.only made comparisons between the four groups

C.compared the four groups with control groups

D.trained the four groups together

Now, my own children are grown and gone. Mom no longer has Dad, and on special , I find myself drawn next door to spend the night with her. So it was late on Thanksgiving Eve, as I slept in the bedroom of my youth, a familiar hand ran across my face to brush the hair from my forehead. Then a kiss, ever so gently, my forehead.

In my memory, for the thousandth time, I the night my young voice , “Don't’ do that anymore----your hands are too rough!” Mom’s hand in my hand, I blurted out how sorry I was for that night. I thought she’d remember, as I did. But Mom didn’t know what I was talking about. She had forgotten ---and ---long ago.

That night, I fell asleep with new appreciation for my gentle mother and her caring hands. And the that I had carried around for so long was nowhere to be found.
