【文章內(nèi)容簡介】 He made a surprising discovery. The ets that had appeared in the years 1531, 1607 and 1682 all had the orbit. Yet their appearances had been 75 to 76 years apart.This seemed very strange to Halley. Three different ets followed the same orbit. The more Halley thought about it, the more he thought that there had not been three different ets, as people thought. He decided that they had simply seen the same et three times. The et had gone away and had e back again.It was an astonishing idea! Halley felt certain enough to make a prediction of what would happen in the future. He decided that this et would appear in the year 1758. There was 53 years to go before Halley’s prediction could be tested. In 1758 the et appeared in the sky.

But this year, Zhang Yan and other physically disabled kids can realize their dream just like any other students. As registration (報名)for this year’s college entrance examinations es closer, the government has made its rules easier on physical examinations for new college students. A new rule was decided together in March by the Ministry of Education, the Ministry of Health and the China Disabled Persons’ Federation. It clearly states that no student should be rejected(拒絕)simply because they have a physical disability. Schools may still advise disabled students on the choice of their major if it is likely to affect their future chances of employment. However ,the final decision will be up to the student. “Now I can try to do my best on the exams. I don’t have to worry that my healthier classmates will get treated better because of my disability,” said Zhang happily. The 18yearold boy will graduate this year from a Chengdu high school in Sichuan Province. He lost an eye during an accident as a child. Zha
