An exciting landing process of Chang'e-4 lunar probe (月球探测器 ) was seen through the monitor at Beijing Aerospace Control Center in Beijing, Jan. 3, 2019. It touched down on the far side of the moon at 10:26 a.m. Beijing Time, becoming the first spacecraft soft-landing on the moon's unknown side never visible from Earth.
China's Chang'e-4 probe has started the exploration on the far side of the moon thanks to the relay satellite that provides a communication link with ground control. The relay satellite, named Queqiao, meaning Magpie Bridge, after a Chinese legend (传说 ) , was launched on May 21, 2018, and became the first communication satellite operating in the halo orbit, nearly 500,000 km from the earth. It can also provide communication for probes from other countries. The relay satellite will also be used for scientific and technological experiments. The maximum distance between the satellite and the Chang'e-4 probe on the far side of the moon is 79,000 km. The satellite processes data from the probe and sends it to Earth.
The satellite can stay in its orbit for a long time due to its relatively low fuel consumption, as the earth's and moon's gravity balances its orbital moving. While in orbit, it can "see" both the earth and the far side of the moon.
The concept of using a relay satellite in the halo orbit was first put forward by U.S. space experts in the 1960s, but was realized by Chinese space engineers.
Researchers hope to use the cameras on the satellite to record asteroids (小行星 ) hitting the far side of the moon. To control the cost of the Chang'e-4 probe, the relay satellite was designed to be relatively small, weighing about 400 kg.
Researchers had just 30 months to develop the satellite, putting them under high pressure. To promote public interest in space exploration, the China National Space Administration invited people to write down their wishes for lunar and space exploration, and the relay satellite carries the names of tens of thousands of participants and their messages.
1.What do we learn from the second paragraph?
A. The relay satellite was launched on Jan. 3, 2019.
B. Chang'e-4 probe was the first communication satellite.
C. The relay satellite only explores the far side of the moon.

A. To reduce the cost as much as possible.
B. To make it circle Moon for a longer time.
C. To avoid being crashed by other satellites.
D. To follow American space experts' advice.’
3.What made researchers suffer from great stress?
A. Few people interested in the exploration on the moon.
B. The relay satellite carrying too much equipment.

B. Chang'e-4 probe lands on Moon's far side.
C. Chinese space engineers make much progress.

请认真阅读下列短文，并根据所读内容在文章后表格中的空格里填入最恰当的单词。注意：每空格1个单词。
Chang'e 3 is a lunar(月球的) exploration mission operated by the China National Space Administration (CNSA), incorporating a robotic lander and China's first lunar rover.
The spacecraft was named after Chang'e, the goddess of the Moon, and is a follow-up to the Chang'e 1 and Chang'e 2 lunar orbiters. The rover was named Yutu following an online poll, after the mythological rabbit that lives on the Moon as a pet of the Moon goddess.
Chang'e 3 achieved lunar orbit on 6 December 2013 and landed on 14 December 2013, becoming the first probe to soft-land on the Moon since Luna 24 in 1976.
In January 2004, the People's Republic of China's lunar orbiter project was formally established. The first Chinese lunar orbiter, Chang'e 1, was launched from Xichang Satellite Launch Center on 24 October 2007 and entered lunar orbit on 5 November. The spacecraft operated until 1 March 2009, when it was intentionally impacted into the surface of the Moon. Data gathered by Chang'e 1 were used to create an accurate 3-D map of the entire lunar surface, assisting site selection for the Chang'e 3 lander.
Chang'e 1's successor, Chang'e 2, was approved on October 2008 and was launched on 1 October 2010 to conduct research from a 100-km-high lunar orbit, in preparation for Chang'e 3's 2013 soft landing. Chang'e 2, though similar in design to Chang'e 1, was equipped with improved instruments and provided higher-resolution imagery of the lunar surface to assist in the planning of the Chang'e 3 mission.
In March 2012, China began manufacturing the body and payload of the Chang'e 3 lander, which will attempt to perform lunar surface and space studies independently of the mission's mobile rover.
Like its orbiting predecessors, the Chang'e 3 mission is planned as a precursor（先驱）to further robotic lunar exploration missions, including Chang'e 5, a sample return mission planned for 2017. Following these automated missions, a manned landing may be conducted around 2025.
Chang'e 3 will attempt to perform the first direct measurement of the structure and depth of the lunar soil down to a depth of 30 m (98 ft), and investigate the lunar crust(壳) structure down to several hundred meters deep.
The development of the six-wheeled rover began in 2002 and was completed in May 2010. It has a total mass of approximately 120 kg, with a payload capacity of approximately 20 kg. It can perform simple analysis of soil samples and may transmit video in real time. It can navigate inclines(斜坡) and has automatic sensors to prevent it from colliding(碰撞) with other objects.
The rover was successfully deployed from the lander, and it made contact with the lunar surface on 14 December. After taking pictures of each other the lander and rover will start their respective science missions. The rover is designed to explore an area of 3 square kilometres during its 3-month mission, with a maximum travelling distance of 10 km.
| Title: Chang’e 3 | ||
| __1.__ | It is a lunar exploration mission operated by CNSA, incorporating a robotic lander and China's first lunar rover. | |
| Name Source | It was named after the goddess of the Moon, __2.__ up the names of Chang'e 1 and Chang'e 2. | |

There was great excitement on the planet of Venus (金星). Venusian scientists managed to land a satellite on the planet Earth, and it has been sending back signals as well as photographs ever since.
The satellite was directed into an area known as Manhattan, named after the great Venusian astronomer Professor. Manhattan, who first discovered it with his telescope 20000 light years ago.
Because of excellent weather conditions and extremely strong signals, Venusian scientists were able to get valuable information as to feasibility (可行性) of a manned flying saucer landing on Earth. A press conference was held at the Venus Institute of Technology.
“We have come to the conclusion, based on last week's satellite landing，” Prof. Zog said, “that there is no life on Earth.”
“How do you know this？” the science reporter of the Venus Evening Star asked.
“For one thing, Earth's surface in the area of Manhattan is made up of solid concrete and nothing can grow there. For another, the atmosphere is filled with carbon monoxide (一氧化碳) and other deadly gases and nobody could possibly breathe this air and survive.”
“What does this mean as far as our flying saucer program is concerned？”
“We shall have to take our own oxygen with us, which means a much heavier flying saucer than originally planned.”
“Are there any other dangers that you discovered in your studies？”
“Take a look at this photo. You see this dark black cloud hovering (盘旋) over the surface of Earth? We don't know what it is made of, but it could give us a lot of trouble and we shall have further tests before we send a Venus Being there.”
“Over here you will notice what seems to be a river, but the satellite findings indicates it is polluted and the water is unfit to drink. This means we shall have to carry our own water, which will add even greater weight to the saucer.”
“If all you say is true, won't this set back the flying saucer program several years？”
“Yes, but we shall continue as soon as the Grubstart gives us the added funds(资金)．” Profession. Zog replied.
1.According to the passage, the Venusian scientists succeeded in getting important information about ________.
A．the feasibility of landing a satellite on Earth
B．the possibility of making a firstrate flying saucer
C．the feasibility of sending a Venus Being to Earth
D．the possibility of directing a flying saucer into Manhattan
2.Why will the Venusian have to take their own oxygen with them when they carry out their flying saucer program because ________.
A．they need it in their way to the planet of Earth
B．the Earth's atmosphere is filled with deadly gases
C．there is a low level of oxygen for Venusians
D．there is no air on the planet of Earth
3.It can be inferred from the passage that ________.
A．landing a manned flying saucer on Earth will be carried out soon
B．Venusians will land on Earth to help to stop serious pollution
C．it's unnecessary to land a manned flying saucer on Earth at present
D．pollution on Earth makes it impossible for Venusians to survive there
4.Where can you probably read such a passage?
A．In a popular magazine.
