On Tuesday, China announced it had grown the first ever plants on the moon, days after landing on the moon’s “far side” Von Karman crater. The cotton seed sprouts (新芽) seemed to have withstood the tough lunar conditions: freezing temperatures, lower gravity levels, and radiation.

But by Thursday, the new cotton seed sprouts had dead already, according to Liu Hanlong, the experiment leader, in a government press conference statement.

After Chang’e-4 landed on the far side of the moon earlier this month, the probe (探测器) was sent a command to remotely water the plants and start the growing process. A tube directed natural light on the surface of the moon into the small container to allow the plants to grow. The probe entered a sleep mode on Sunday, the first lunar night after the probe’s landing.

Professor Xie Gengxin, professor at Chongqing University and chief designer of the experiment, told CNN that it ended after nine days when the control team shut down the power. Xie said temperatures inside the biosphere had grown too abnormal and reached extremes that would likely kill all life, including the seeds and eggs during the lunar night. Xie didn’t confirm why temperatures had risen to levels unbearable for the plants in spite of the measures taken by the research team.

Even though the experiment was quickly terminated, Xie considered it a success. The cotton were the only seeds to sprout, however, and despite many assumptions about the future possibility of moon clothes, the cotton plant’s main purpose this time was to give researchers the valuable data on how to cultivate life in the moon’s tough conditions. The eventual ability to grow plants on the moon could prove useful for long-term space missions, like a trip to Mars. Astronauts could theoretically harvest their own food in space, avoiding the need to return to Earth to resupply.

Aside from the apparent failure of the biological or plant experiment, the rest of China’s mission to the far side of the moon appeared on track as of Thursday. The historic mission is intended to accomplish a range of tasks, including conducting the first lunar low-frequency radio astronomy experiment and exploring whether there is water at the moon’s poles.

Chang’e-4 is the latest step in China’s robotic lunar-exploration program, named after a moon goddess in Chinese mythology. China plans to launch the Chang’e-5 sample-return mission sometime this year.

On Dec 22, China became the third country in the world after Japan and the US to have a carbon dioxide（CO2）monitoring satellite.

Named Tansat, as "tan" is the Chinese word for carbon, the satellite moves around Earth at about 700 kilometers above the ground. There, it can “see” clearly how much CO2 there is in the air and how it is moving.

How is TanSat able to do that？When sunlight travels through the air, the CO2 molecules（分子）take in different colors from the light. The satellite then looks at these colors to find out how much CO2 there is in the air.

“The TanSat has very good vision（视力）, and it can tell changes in CO2 as small as 1 percent, ” said Yin Zeng shan, one of the satellite's designers at the Chinese Academy of Sciences, according to Xinhua News Agency.

But there is a question. When CO2 can already be measured from ground stations, why do we need a satellite that does the same thing？

The truth is that they don't do exactly the same thing. According to Zhang Peng, vice director of the National Satellite Meteorological Center, the data from ground stations is limited and it does not cover the ocean area, which takes up more than 70 petcent of Earth's surface.

But TanSat has solved the problem. It has a bird's eye view of the Earth, covering both the land and the ocean. It can also change its mode（模式）and position when looking at the ocean area because the water can reflect light. This light may change the data if its normal mode is used.

More importantly, China is now working on its goal of producing less CO, , starting from 2030 or earlier. To meet that goal, it will need to keep track of every bit of progress that it's making.

And with TauSat, China will have first-hand, detailed data of CO2 emissions in different areas, provinces and parts of the ocean, no longer having to use data from Japan and the US.

1.Which of the following about TanSat is TRUE？

A.It collects the CO2 in different areas above the ground.

B.It gets CO2 data by studying the colors of air.

C.It has been developed with the help of Japan and the US.

D.It has different modes to suit different weather conditions.

2.By reporting that the TanSat has very good "vision", the article shows that_______________.

A.the satellite uses many different kinds of cameras.

B.the satellite is very sensitive.

C.the satellite can capture every change in CO2.

D.the satellite can reflect light at 700 kilometers above the ground.

3.What can be concluded from the last paragraph?

A.TanSat is specially designed to reduce China's CO2 emissions.

B.China did not have any detailed data of CO2 emissions before.

C.TanSat will play a key role in helping to reduce China's CO2 emissions.

D.China is going to share its data of CO2 emissions with other countries.

4.What could be the best title for the passage?

A.Making great achievements B.Cutting CO2 emissions

C.Monitoring the ocean D.Checking more carbon

The first robot rover to land on the Moon in nearly 40 years, China's Jade Rabbit, has begun sending back photos, with shots of its lunar lander(登月飞行器). Jade Rabbit rolled down a ramp lowered by the lander and on to the volcanic plain known as Sinus Iridum at 04：35 Beijing time on Saturday (20：35 GMT)．It moved to a spot a few metres away, its historic short journey recorded by the lander. On Sunday evening the two machines began photographing each other. A Chinese flag is clearly visible on the Jade Rabbit as it stands deployed on the Moon's surface.

Ma Xingrui, chief mander of China's lunar programme, declared the mission (任务)a “plete success”. The first soft landing on the Moon since 1976 is the latest step in China's ambitious space programme, says BBC science reporter Paul Rincon.

The lander will operate there for a year, while the rover is expected to work for some three months. The Chang'e­3 mission landed some 12 days after being launched atop a Chinese­developed Long March 3B rocket from Xichang in the country's south. The official Xinhua news service reported that the lander began its descent(下降)on Saturday just after 13：00 GMT, touching down in Sinus Iridum (the Bay of Rainbows) 11 minutes later. “I was lucky enough to see a prototype rover(原型月球车) in Shanghai a few years ago ­ it's a wonderful technological achievement to have landed，” Prof Andrew Coates, from UCL's Mullard Space Science Laboratory, told BBC News.

Chang'e­3 is the third unmanned rover mission to touch down on the lunar surface, and the first to go there in more than 40 years. The last was an 840kg (1,900lb) Soviet vehicle known as Lunokhod­2, which was kept warm by polonium(钋)­210. But the six­wheeled Chinese vehicle carries a more sophisticated payload(复杂的有效负荷), including ground­penetrating radar which will gather measurements of the lunar soil and crust.

1.What does the text mainly talk about?

A．China's space and aeronautics industry develops quickly.

B．The importance of China's space and aeronautics industry.　　

C．China's Jade Rabbit Moon rover sends back first photos.

D．Chang'e­3 is the third unmanned rover mission to touch down on the lunar surface.

2.After ________ years' hard and scientific work, the first soft landing on the Moon has made such great progress.

A．nearly 40　     B．37

C．64　     D．more than 40

3.The purpose that the Chinese moon rover has visited the moon is to ________.

A．do some research about the moon

B．be the first settler on the moon

C．to plant the Chinese flag onto the moon

D．send a lovely jade rabbit onto the moon

4.From the text, we know that the lander began its descent on Saturday just after ________ Beijing time.

高三英语单项填空简单题查看答案及解析

Humans have launched themselves into the outer space. They’ve landed on the moon. They’ve built habitable space stations that orbit the Earth. The next giant leap for mankind is to reach another planet – specifically, Mars.

The problem is that it’s no easy task. The planet is 586 times further away from the Earth than the moon, and it’ll take around 180 to 220 days to reach Mars, depending on where each planet is in its orbit. Such long periods in space have suggested many potential health problems, including hormonal changes, skin conditions, and muscle and bone deterioration (损耗).

Here’s where some furry friends come in. A wide range of animals have been in space, from fruit flies and spiders to cats, and dogs. Such experiments began as far back as the late 1940s in first tests to see if living things could withstand the extreme g-force (重力) of a rocket launch.

Mice continue to play a very important part in space experiments, mainly because the animals make excellent test subjects. They’re small, which makes them inexpensive and easy to care for. In addition, their size and short life span make it possible to do the equivalent of several human years of tests in a much shorter time. Finally, because mice are mammals, they share many common characteristics with humans in terms of genetics, biology and behavior.

Astromice have hit the headlines recently, as a team of scientists led by Betty Nusgens, professor of biology at the University of Liege in Belgium, found that the mice suffered a 15 percent thinning of their skin after 91 days aboard the International Space Station (ISS).

This experiment was part of a wider NASA mission (任务) called the Mice Drawer System (MDS). The Italian Space Agency developed the facility, which allows six mice to be housed, monitored, and automatically fed and watered aboard the ISS, among which three survived during the mission.

The mice have participated in 20 separate experiments, to study such effects as osteoporosis (骨质疏松症), anemia (贫血) and heart health.

Results for the 20 experiments are coming in gradually. But it’s clear that mice continue to play an important role in the ongoing quest to conquer the final frontier.

1.We can infer from Paragraphs 2-3 that ______.

A. Mars is the farthest planet away from Earth discovered so far

B. the journey to Mars could put humans’ health at risk

C. it was in the late 1940s that animals were first sent to the ISS

D. animals that have been sent into space have mostly survived

2.The underlined word “withstand” in Para.3 means _________.

A.set up　　 　　 B. hold up

C. work out　　 D. come across

3.According to Betty Nusgens and her team, the mice aboard the ISS ______.

A. suffered the loss of part of their skin

B. all survived for the duration of the mission

C. were fed and watered by the astronauts

D. participated in 20 experiments that made great breakthroughs

4. The main purpose of the article is to _____.

A. describe the role mice play in scientific research

B. report on the results of the Mice Drawer System

C. analyze how mice could pave the way to Mars

D. change people’s traditional attitudes toward mice
