What kind of reading answers in space house, reading answers for space junk

At about 9 o'clock in the evening of September 29, the Tiangong-1 target vehicle was successfully launched, unveiling China's first space rendezvous and docking. In the near future, Chinese astronauts will take the Shenzhou spacecraft to carry out manned rendezvous and docking with Tiangong-1, and enter Tiangong-1 to work and live. What does the interior of Tiangong-1 look like?

How to live in it? We ask the astronauts to take you a**.

At present, it is the largest and heaviest spacecraft in China.

From the manned space launch site of the Jiuquan Satellite Launch Center, the astronauts carried the Shenzhou spacecraft into space, flew to a predetermined orbit more than 300 kilometers from the earth, and gradually approached Tiangong-1. Tiangong-1 is currently China's largest and heaviest spacecraft in orbit. From the appearance, it can be seen that different from the three-compartment structure of the spacecraft, Tiangong-1 is a two-compartment structure of the aircraft, and the two cabins are the experimental module and the resource module.

The resource module is powered to provide energy for the flight; The experimental module is where the astronauts work and live, and it is here that the astronauts are ready to enter. The cabin is a normal environment suitable for human survival and life, and the temperature, humidity, and oxygen are almost the same as those on the earth.

The living and working area is a two-bedroom apartment.

During the rendezvous and docking, Tiangong-1 was passive, and the Shenzhou spacecraft was active. Once it becomes a combination, the control system of Tiangong-1 acts as the "brain" to control the entire assembly. After the atmospheric pressure in the cabin becomes normal and everything is ready, the astronauts can easily open the door of the Shenzhou spacecraft and enter the sealed passage.

Since there is no gravity in space, people drifted into Tiangong-1 along this passage with a diameter of about one meter. Since it is in the capsule, the astronauts do not have to wear bloated spacesuits, but ordinary blue overalls.

Inside Tiangong No. 1 is a cuboid room. The entire event space is about 15 cubic meters. From the perspective of structural layout, the entire living and working area of Tiangong No. 1 is a two-bedroom and one-living room.

In the middle is a long hall, and on the left and right are two bedrooms, providing a place to rest and sleep. Tiangong-1 is currently able to support the life and work of two people. The hall is divided into different areas, including a storage area, an exercise area, a science experiment area and an instrument operation area.

Create a terrestrial living environment.

Many of the new technologies adopted by Tiangong-1 are also aimed at the development of the future space station, shouldering the important task of laying the foundation for the future, and there are many invisible "care" in it. Tiangong-1 has an environmental control life support system, which is mainly responsible for the control of the atmospheric environment in the capsule of Tiangong-1 and Shenzhou spacecraft, including temperature, humidity, cabin pressure, oxygen, etc., to create a human living environment similar to the ground, and even responsible for the discharge of harmful bacteria produced by the human body.

When the astronauts return to the Shenzhou spacecraft and initiate the evacuation order, the spacecraft and Tiangong-1's docking mechanism are separated, and they can return to Earth. It is understood that as soon as the first half of next year, three astronauts will actually visit this brand-new space home.

1.What are the characteristics of Space Furniture?

2.What does the interior of Tiangong-1 look like? How to live in it? "What is the role?

3。Why does the space home in the text make astronauts feel at home?

4.Please tell us about your overall impression of Tiangong-1 (from the internal structure, internal environment, scientific and technological influence, etc.).

1 In accordance with the explanation of this article, the following three phrases are copied in the margins of the first paragraph. Phrase: Adding a layer of pollution to the earth threatens the safety of human life and affects the development of the aerospace industry.

2 The following information is obtained from the text, in which position should it be placed in the four positions of A, B, C, and D that have been indicated in the text?

In 1983, the American space shuttle "Challenger" collided with a piece of paint stripping with a diameter of 0 2 mm, which caused damage to the porthole and had to stop flying.

3 The article says that the hidden danger of space junk is set by human beings, and the reason for this is that

4 An excerpt from the article that illustrates the "continuous spread" of thousands of tons of garbage in space.

Answer: "Space Junk - A Hidden Danger of Human Beings":

1 In order: affecting the development of the aerospace industry, adding a layer of pollution to the earth, and threatening the safety of human life at all times.

2 d3 Space junk is a variety of objects and debris left in space by humans during space activities.

4 According to statistics, about 1,000 tons of space junk are currently "orbiting" around the Earth, and the amount is increasing at a rate of 2 to 5 per year. (Or: According to statistics, by the next century, there will be more than 100 such devices containing more than 1 ton of radioactive material.) ）

5 Space junk collides with other objects and has tremendous destructive power. Nuclear devices in space junk will cause severe radioactive contamination of the planet.

6 Examples of sub-column numbers.

True or False, the Astronaut Shampoo is a special leave-in shampoo, and this shampoo can also be used on Earth.

17.Each step is completed according to the established plan, and the fingers are quite flexible in each operation; more perfect than the spacewalks of the former Soviet Union and the United States; All the functions of the spacesuit were successfully realized during the entire out-of-cabin activity.

18.Give examples, list data, make comparisons; Being able to list the relevant data of the errors made by astronauts in the former Soviet Union and the United States during their spacewalks and compare them with Shenzhou 7 fully shows that Zhai Zhigang's spacewalks are more perfect. There is no uniform answer to the last question.

Example: Former Soviet cosmonaut Leonov was in danger and violated operating procedures when he left the capsule, but Zhai Zhigang completed every step according to the established plan.

19.The former is a combination of direct and indirect citations, and the latter is just indirect citations; Citing expert evaluations enhances the persuasiveness and authenticity of the article.

20.(1) The spacewalk time of Shenzhou 7 was completely planned, and the Americans took too long, because it took a full 5 minutes to close the hatch, and the whole time must have exceeded the scheduled time.

2) The former uses a metaphor to illustrate that the astronaut's fingers and actions are quite flexible, and the latter also uses a metaphor to illustrate that the spacesuit swells badly and seriously affects the astronaut's operation.

3) No, because the use of these two related words can emphasize that all movements are quite flexible, which means that the process of exiting the cabin is more perfect.

(1) Each step is successfully completed according to the established plan, and the fingers are flexible and the movements are easy.
