8、ion period than Mers-cov.BWe had a military training for a whole week in late August after stepping into our new senior high school. The military coaches were all strict with us. Frankly speaking, we all felt very tired, and even had pains in our legs. However, we all persisted in practising, and fe

9、lt satisfied with ourselves eventually.In the morning we arrived at the playground in lines on time. Then you could hear our military coaches shout at the top of their voices “Stand at attention”, “Stand at ease”, “Tum left”, “March”, “Run”, All the students were practicing carefully. Exhausted as w

10、e were, none of us asked to have a rest, none of us complained, none of us wanted to drop out. Under the blazing sun, despite high temperature and thirst, we stood still for an hour with sweat dripping down from our faces all the time. In the moonlight, we played games heartily, bursting into laught

11、er now and then. On the grass, divided into two groups, we competed to sing encouraging military songs in high spirits one after another. At the meeting, hearing their moving speech, we felt regretful for wasting time before. At that time we realized we should have been grateful to our parents and t

12、eachers, with tears in our eyes. And we all made up our minds to study harder. On the afternoon of the last day, our principal sang high praise for our behaviour, and encouraged us to keep this persistent spirit in future.Though this military training is a tough experience, we challenged ourselves a

13、nd overcame those difficulties. We felt proud from the bottom of our hearts.

Researche

17、rs say because mices genes are so similar to humans, their findings could lead to the treatment of more genetic diseases. Scientists at the University of California, Davis studied information from a data bank of mices genetic material. They found 347 genes linked to eye problems, with just 86 of the

18、m having been studied in the past. Only around 50 to 75 percent of hereditary eye diseases in humans can be explained with present science- The researchers believe these hundreds of new genes found in mice could be a key to explaining 一 and therefore being able to treat the other 25 to 50 percent. “

19、This is extremely valuable for people with hereditary eye disease,” said researcher Professor Ala Moshiri. “All researchers are going to start using these data. In the past, we knew the problem was there but we didnt know where to look. Now eye centers can call back patients and screen them for thes

20、e new genes. We expect that more and more of these genetic diseases will be treatable. Also, the fact is that more than 60 percent of eye problems at birth are ones resulting from the babys parents! Thanks to data from the International Mouse Phenotyping Consortium(IMPC) , which is trying to work ou

21、t what every single gene in a mouse is responsible for, with the aim of translating it to humans, scientists are moving closer to figuring out all genetic causes of blindness. To do this, scientists separate a single gene from other ones at a time and then observe what effect it has on the mouse for

22、 a long time. This has so far been clone more than 7 ,000 times and has achieved great success. Researchers are now working alongside eye care centers in Texas and Iowa in order to compare the mices genes to those of patients.8.How many hereditary-sight-loss-related genes were new-found?A.86.B.261.C

23、.300.D.347.9.Why is the percentage of genetic eye problems mentioned in paragraph 3?A.To show the significance of studying mices genes.B.To prove mices genes are similar to humans.C.To warn the high risk level of suffering them.D.To explain how common they are among people.10.What should scientists

25、roblemsC.Genetic Diseases Discovered in MiceD.Humans Genes Causing Eye DiseasesDNew research suggests that dogs might be able to help save diseased citrus trees.A group of scientists trained dogs to use their sense of smell to detect a crop disease called citrus-greening. The disease has affected or

26、ange, lemon and grapefruit trees in the American states of Florida, California and Texas.The dogs can detect the disease weeks to years before it appears on tree leaves and roots, the researchers report. A study on their findings was published recently in the Proceedings of the National Academy of S

27、ciences. The report says using dogs is also faster, less costly and more exact than having people collect hundreds of leaves for lab analysis.Timothy Gottwald is a researcher with the U. S. Department of Agriculture and a 7 co-writer of the study. He told The Associated Press, “This technology is th

28、ousands of years old-the dogs nose. Weve just trained dogs to hunt new prey.”Citrus-greening is caused by a bacteria(细菌) that is spread by a tiny insect that feeds on the leaves and stems of citrus trees. Once a tree is infected, there is no cure. The disease has also hurt citrus crops in Central an

29、d South America and Asia. In one experiment involving grapefruit trees in Texas, trained dogs were correct 95 percent of the time in telling the difference between newly infected trees and healthy ones. “The earlier you detect a disease, the better chance you have at stopping an epidemic (流行病) by re

30、moving infected trees,” Gottwald said.Matteo Garbelotto studies plants at the University of California, Berkeley. He says the new research shows that dogs can detect an infection well before current methods. Garbelotto has been involved in similar research but had no part in the new study.Laura Sims

31、 is a plant scientist with Louisiana Tech University. She praised the steps taken to find out if the dogs were detecting the bacteria itself or a plants reaction to an infection. To do that, the researchers infected different kinds of unrelated plants with the bacteria in a laboratory. The dogs were

32、 still able to pick out the infected plants.Gottwald said, “Youve seen dogs working in airports, detecting drugs and explosives. Maybe soon you will see them working on more farms. ”12.According to the research, trained dogs can _.A.help infected trees recover from diseasesB.recognize a crop disease

33、 in its early stageC.cause fruit trees to grow faster than usualD.reduce the cost of planting some fruit trees13.What does the underlined part “new prey” in Paragraph 4 refer to?A.Infected plants.B.Fruit trees.C.Tiny insects.D.Favourite foods.14.Why did the researchers do experiments on unrelated pl

34、ants?A.To further prove the findings.B.To explore the plant diseases.C.To present different opinions.D.To discover a plants reactions.15.How does Gottwald feel about the future use of this new method?A.Doubtful.B.Positive.C.Indifferent.D.Curious.第二节（共5小题；每小题2.5分，满分12.5分）根据短文内容，从短文后的选项中选出能填入空白处的最佳选项。
