If we are wise, we accept these failures as anecessary part of the learning process. But all too often we convey to our children either by words or by actions

2、 that failure is something to be ashamed of, that nothing but top performance meets our approval（赞许）.Donnie was my youngest third-grader. Hisfear of failure kept him from classroom games that other children played excitedly. Heseldom answered questions he might be wrong. He seldom finished his work

3、because he repeatedly checked with me to be sure he hadnt made a mistake.I tried my best to build his self-confidence. But nothing changeduntilmidterm, when Mary Anne, a student teacher, was assigned to our classroom. She was young and pretty, and she loved children. My pupils, Donnie included her.

4、But even enthusiastic, loving Mary was baffled by this little boy who feared he might make a mistake.Then one morning we were working math problems. Donnie had copied the problems with painstaking neatness and filled in answers for the first row. Pleased with his progress, I left his children with M

5、ary. But when I returned. Donnie was in tears. Hed missed the third problem.Mary looked at me in despair. Suddenly her face brightened. From the desk we shared, she got a canister（小筒）filled with pencils.“Look, Donnie,” she said. “Ive got something to show you.” She removed the pencils and placed the

6、m on his desk. “See these pencils, Donnie?” she continued. “They belong to Mrs. Lindstrom and me. See how the erasers are worn? Thats because we make mistakes too. Lots of them. But we erase the mistakes and try again. Thats what you must learn to do, too.”She kissed him and continued: “Ill leave on

7、e of these pencils onyour desk so youll remember that everybody makes mistakes, even teachers.” Donnie looked up with love in his eyes and just a glimmer（少许）of a smile.ThePencil became Donnies prized possession.

8、sses. graduallypersuaded him that its all right to make mistakes as long as you erase them and try again.21. Why did Donnie rarely finish his work?A. Because he seldom answered those difficult questionsB. Because he spent too much time checking his answersC. Because he couldnt work together with his

9、 classmatesD. Because he never did his work until the very last minute22. The word “baffled” in Paragraph 3 most probably means .A. encouraged B. impressed C. satisfied D. confused23.

They are big, cl

11、ever, and sociable. But what if someone told you that they may also hold the key to fighting cancer?People have been wondering why elephants do not develop cancer, even though they have life spans（寿命）that are similar to humans, living for around 50 to 70 years.Now scientists believe they know why. A

12、 team at the University of Chicago, Us has found that elephants carry a large number of genes that stop tumors（肿瘤）from developing. To be precise. They found 20 copies of an anti-tumor gene called TP 53 in elephants. Most other species. Humans included, only carry one copy.According to the research,

13、which was recently published on the online science network BioRxiv, the extra copies of the gene improved the animals sensitivity to DNA damage. This lets the cells（细胞）quickly kill themselves when damaged before they can to on to form deadly tumors.“An increased risk of developing cancer has stood i

14、n the way of the evolution of large body sizes in many animals,” study author Dr Vincent Lynch told The Guardian. If every living cell has the same chance of becoming cancerous, large creatures with long life spans like whales and elephants should have a greater risk of developing cancer than humans

15、 and mice do. But across species, the risk of cancer does not show a connection with body mass.This phenomenon was found by Oxford University scientist Richard Peto in the 1970s and later named “Petos paradox”. Evolutionary biologists believe it results from larger animals using protection that many

16、 smaller do not, In the elephants case, the making of TP53 is natures way of keeping this species alive.The study also found that when the same genes were brought to life in mice, they had the same cancer resistance as elephants. This means researchers could use the discovery to develop new treatmen

17、ts that can help stop cancers from spreading or even developing in the first place.“Nature has already figured out how to prevent cancer,” said Joshua Schiffman, an oncologist at the School of Medicine, University of Utah, US.“Its up to us to learn how different animals tackle（对付）the problem so we c

18、an use those strategies to prevent cancer in people.”25. Why are elephants unlikely to develop cancer?A. They have a large body size B. Their genes suffer no DNA damageC. Certain genes in their body kill existing tumorsD. They carry many genes that keep tumors from developing26. According to Dr. Vin

19、cent Lynch, what has been a risk in the evolution of large animals?A. Extreme weather B. Human behaviorC. A risk of deadly tumors D. Cells killing themselves27. What does the underlined expression “this phenomenon” on the sixth paragraph refer to?A. Larger animals have protection from TP53 B. The ri

20、sk of cancer is not related to body sizeC. The larger animals are, the bigger risk of cancer they haveD. Larger animals suffer the same risk of cancer as smaller ones do28. We can conclude from the last three paragraphs that .A. the TP53 genes have proven useful in stopping cancer in miceB. dependin

21、g on nature is not enough to fight against cancerC. this new treatment is more effective than the present onesD. humans are expected to stop cancer in the near futureCBrawn Nelson knew he wanted to be a doctor at 8 after he acted as a doctor on a primary school career day.He faced more difficulties
