Before Chinese Chang’e-2, the US sent up a space probe (探测器) to hit the moon to see ______.

高三英语单项填空中等难度题查看答案及解析

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.

D. The relay satellite can handle data from Chang'e-4 probe.

2.Why was the size of the relay satellite relatively small?

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.

C. Their lacking enough time to develop the relay satellite.

D. People's never being optimistic about the relay satellite.

4.What is the main idea of the text?

A. China is a new space power after the USA.

B. Chang'e-4 probe lands on Moon's far side.

C. Chinese space engineers make much progress.

D. Space exploration is a dangerous challenge.

China's newest space laboratory,TiangongⅡ,will be sent up into the air from the Jiuquan Satellite Launch Center in Northwest China.It will provide more comfortable digs for astronauts living aboard.

Zhu Zongpeng,chief designer of TiangongⅡsaid designers aimed to create an astronaut-friendly environment in every regard when they refitted the space lab that was developed based on Tiangong Ⅰ.

"A number of particulars were taken into account,including the sound,lighting,inner decorations as well as support equipment.For instance,the carpet in Tiangong I was replaced with floorboards.We fixed a foldable, multifunctional table that can be used for dining and experiments.The light is softer and can be adjusted.Each astronaut has a bed lamp.We also equipped the astronauts with Bluetooth headsets and Bluetooth speakers."Zhu added.

The Tiangong Ⅱconsists of two cabins（舱）with separate functions—the experiment cabin is sealed and acts as the astronauts' living quarters,while the resource cabin contains solar panels（太阳电池板）,storage batteries,engines, etc.

The lab has about 15 square meters for astronauts to live and work,including a separate sleep section and waste storage area.The equipment in the spacecraft ensures its inner sound under 50 decibels（分贝）.The temperature within the experiment cabin is kept between 22℃ and 24℃ and the humidity（湿度）between 45 and 55 percent.

In addition,Tiangong Ⅱ has an air detector（空气探测器）,and it can be used to check and deal with more than 20 dangerous gases.Also,designers placed exercise equipment in the space lab to help astronauts keep healthy and its communication systems also allow astronauts to receive and reply to emails and make calls to family and friends.

1.What does the underlined word "digs" in Paragraph 1 probably mean?

A. Rooms.　　 B. Temperature.

NASA-s New Horizons probe（宇宙探测器）flew by Pluto（冥王星）this morning, sending back history's first up-close looks at the vast freezing-cold world.　 Closest approach came at 7:49 a.m.　 EDT.　 To celebrate, NASA gave out the latest photo of Pluto. It showed a reddish world with an amazing heart-shaped feature on its surface.

After today's close encounter, all the nine solar system's traditionally recognized planets have now been visited by a spaceship-a huge project begun in 1962 when NASA's Mariner 2　 probe flew past Venus,　 a　 planet　 in　 the solar system.　 More than　 l,200 scientists, NASA guests and important persons, including 200 reporters, watched the flyby live at New Horizons'　 mission control center.

That close encounter has been a long time coming. The$723 million New Horizons mission launched in January 2006 but began taking shape in 1989.　 "New Horizons is'a capstone mission'," Glen Fountain, mission project manager told Space, com. "It is the first completion of the observations of our solar system. It-s giving us a new idea about how we human beings fit into the universe."

New Horizons "faced a crazy number of challenges," Stern, a driving force behind New Horizons said, "So many people stuck with this for so long. They got knocked down; they stood up.　 They got knocked down again; they stood up again.”

In a coincidence, today's close approach falls on the 50th anniversary of the first flyby of Mars, another planet, which was completed by NASA-s Mariner 4 spaceship.

There are no longer nine officially recognized planets, of course. The International Astronomical Union regarded Pluto as “a dwarf planet" in 2006 in a decision that remains controversial（有争议的）today.

1.Which statement is TRUE according to the passage?

A.　 Ideas still vary in the identity of Pluto.

B. Only scientists could watch the flyby live.

C. Mars is the first planet visited by a spaceship.

D. New Horizons mission aimed to observe the solar system.

2.Glen Fountain may probably agree that　 _____________________．

A.　 it is the most difficult to land on Pluto in the solar system

B. New Horizons mission is a long and troublesome project

C. their strong determination leads to the successful flyby

D. people are likely to find new ways to fit into space

The summer before my dad died, we moved house. Up until that point, our family had our own space to spread out. Money was tight, so there was no television set, but we owned a turntable on which my dad’s records played constantly. Mostly, it played Bob Dylan. Tracks from The Basement Tapes and Desire became an important part of our new life. My brother and I, aged 8 and 10, climbed trees, built hideaways and learned the words of Clothes Line Saga. We would chant over the, lost in our own joy.

It was January when my dad left us forever because of the cancer. He was 36 going on 37 then, the same age as Dylan.

Growing up, I remained a fan of the music, but I wasn’t obsessed with Dylan until one day in early 1995, my brother bought us both tickets to see him play at Brixton Academy. London felt like a long way to go. But finally seeing Dylan step out onto the stage brought a sudden rush of excitement.

I have seen Dylan a couple of times since. My brother is not around so much these days. But he was up for a visit recently.
