I.阅读理解
A
No human has set foot on the Moon since 1972. Now, after more than four decades of inactivity,
interest in putting humans back on the Moon is finally heating up again. But who will get there first？
CHINA
On 14 December 2013, China successfully landed its Jade Rabbit rover（探测车）on the Moon. It is
now working on its next exploration mission. Named Chang'e 4, the mission is scheduled to touch down in
the Aitken Basin near the end of 2018. If successful, it will be the first landing on the Moon’s far side.
RUSSIA
Russia plans a manned Moon landing in 2030. It is currently working on a project whose idea is that
the landers will explore the south pole of the Moon, exploring for resources such as minerals and water ice
to be used to provide for a human outpost（前哨站）.
INDIA
Following the success of its Chandrayaan-1 in 2008, India announced a follow-on mission.
Chandrayaan-2 was meant to cooperate with Russia. But when the Russians failed to deliver the promised
lander in 2013, India decided to go it alone. Chandrayaan-2 is about to be sent up in 2018.
U. S. A.
In December 2018, NASA plans to send up the Exploration Mission 1, an uncrewed test of their Orion
astronaut capsule in which the craft will circle around the Moon before returning to Earth. All being well, a
crewed capsule will follow in 2023. Should the mission prove a success, the astronauts will be the first
humans to see the far side of the Moon with their own eyes since Apollo 17 in 1972.
1. What will China do in its next space mission？
更多资料添加微信号：hiknow_007 淘宝搜索店铺：乐知课堂A. Improve its Jade Rabbit rover.
B. Work with other countries.
C. Land Chang’s 4 on the Moon.
D. Explore the south pole of the Moon.
2. Why did India try to carry out its follow-on mission alone？
A. It couldn’t find a partner.
B. It didn't get the lander as planned.
C. The Russians refused to work with India.
D. It planned to launch Chandrayaan-2 in advance.
3. Which country is interested in resources on the Moon？
A. Russia. B. China. C. India. D. U. S. A.
4. What can we know from the text？

B. China will be the first to see the far side of the Moon.
C. U.S.A. will send a crewed capsule to the Moon in the future.
D. Humans have kept active in exploring the Moon since 1972.
B
The sky is a large place，and though it has been carefully examined for centuries，new features still
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
circuit of the sun.
Some astronomers have speculated that Mr Kowal's discovery may be the first indication of an
asteroid（小行星）belt beyond Saturn.
5. What may have been found in the solar system according to the first paragraph？
A. A small new planet. B. A new solar system.
C. A large new object. D. A large new planet.
6. What can we learn from the second paragraph？
A. What the object is like.
B. How the object was found.
C. Where the astronomers live.
D. Why the object was moving.
7. What magazine might this passage be taken from？
A. Astronomy. B. Industry. C. Spaceflight. D. Agriculture.

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.
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.
