turn up. Last March it was the rule of Uranus（天王星），and last week astronomers announced what
may turn out to be a new planet，though a very small one，in the solar system.
The object was first sighted last month by Charles Kowal，an astronomer at the Hale Observatories in
Pasadena，Calif. Mr Kowal observed a faint trail of light on photographic plates ，indicating that
something was moving in relation to the background of stars. Other observers have confirmed the
更多资料添加微信号：hiknow_007 淘宝搜索店铺：乐知课堂discovery.
The “mini-planet”，identified for the time being as “Object-Kowal”，appears to be about 1. 5 billion
miles away，between the orbit of Saturn and Uranus，and its diameter（直径）has been estimated at
between 100 and 400 miles. Its orbit has not been determined yet，but if the orbit proves to be roughly
circular，like that of the major planets，the new object would probably take 66 to 70 years to make a

Shooting for the Stars
Tereshkova flew into space on June 16,1963,on the three-day Vostok 6 mission.After 48 orbits and 71
hours,she returned to Earth,having spent more time in space than all U.S.astronauts combined to that date.
1
A textile worker from a modest family,Tereshkova became interested in parachuting at a young age.
2 Tereshkova and four other women were part of the first all-female cosmonaut training group in
1961,but only Tereshkova ever completed a flight.
After Tereshkova’s landmark mission,it would take another 20 years for the United States to send a
woman into space. 3 Since then,a total of 57 women from nine different countries have blasted off.
Chinese astronaut Wang Yaping heads for the launch site shortly before her mission to dock with a
space lab on June 11.
4 NASA astronaut Karen Nyberg was aboard the International Space Station and China sent its
second-ever female astronaut,Wang Yaping,to work on its orbiting space module.However,Tereshkova
remained the only woman to complete a solo flight.
In recent years,NASA has run into trouble with funding. 5 However,this new class of astronaut
candidates suggests that NASA is looking ahead to the future of space exploration.The group includes the
first female fighter pilot to become an astronaut in almost two decades,as well as a female helicopter pilot.
更多资料添加微信号：hiknow_007 淘宝搜索店铺：乐知课堂A.Since then,many astronauts have conquered the space.
B.Two women have been in orbit in recent years.
C.However,her parents thought it dangerous to do so and tried to stop her.
D.Currently,there are no American spacecraft that can carry humans to space.
E.Sally Ride became the first female American woman to leave Earth on June 18,1983.
F.It took place just two years after Yuri Gagarin achieved the first piloted spaceflight in 1961.
G.Her experience in parachute jumping led to her being selected as a cosmonaut by the Russian
government.
【语篇解读】本文是一篇说明文。1963年6月16日,俄罗斯宇航员捷列什科娃进入太空,成为第一位
进入太空的女宇航员。
【答案与解析】
1.F 上文提到“1963年6月13日,Tereshkova进入太空……”,F项中的“It took place just two
years...in1961.”和上文的1963时间正好吻合。
2.G 根据下文的“Tereshkova和其他四位女士是1961年全女士宇航员训练队的一部分人员”可知,
上文应该是提到她被选为宇航员,所以选G项。
3.E 根据上文的“美国又用了20年才把女性送入太空”可知,E项与此语境相符。
4.B 根据下文的“NASA astronaut Karen Nyberg”和“WangYaping”可知,上文应该提到两位宇航
员,所以选B项。
5.D 根据上文的“近几年美国航空航天局资金困难”可知,美国暂时没有载人航天计划,所以选D项。

参考范文
Dear Editor,
Recently our class has had a discussion about whether the clone research should be carried out.
Some of the students are for the clone research. They say cloning is of help in researching into the
cures for many diseases as well as useful for saving endangered animals. Cloning human cells in a lab
could offer perfect organs for patients to transplant. However, others are against it. Though cloning might
improve the quality of life, it might bring about some genetic changes. It also might raise ethical problems.
Personally, cloning should be dealt with carefully and monitored closely by the government, because
we don’t understand enough what effects cloning will have on the world in the future.
Yours,
Li Hua
