山东省日照市2021年中考英语真题试卷

阅读下列短文,从每小题所给的A、B、C、D四个选项中选出最佳答案。

Earthquake rescue (救援) robots experienced their final tests in Beijing, The inventors of this robot said with this robot, rescuers would be able to buy more time to save lives during an earthquake.

This kind of robot is able to fly. It's about three meters long, and it took about four years to develop the model. Its main function is to collect information from the air and send goods of up to 30 kilos to people trapped (困住) by an earthquake. It has an excellent camera which can provide very clear pictures. It can work day and night, and is also able to send the latest pictures from the quake area.

Dr. Qi Juntong, a researcher from Tsinghua University, said, "The most important character of this flying robot is that it doesn't need a control from faraway paces. We just set in it the information of the places where it should go, and then it takes of, and lands by itself. It flies as high as 30000 meters, and as fast as 100 kilometers per hour."

This robot has a different function一it can change as the environment changes. Its main job is to search for any signs of life in places where human rescuers are unable to go. The camera, also acting as a detector (探测器) that finds trapped people and detects harmful gases, is placed in the robot, which can work in the dark, With its 10 - mer - long pipe in the robot, people who are trapped in the fallen buildings will be able to get supplies including oxygen (氧气) and water.

Experts have said that the robots would enter production and serve as part of the national earthquake rescue team as soon as possible.

(1)、In what way is the robot different from others, according to Dr. Qi?
A、It has a very special shape B、It is able to fly everywhere C、It works with no information set in D、It doesn't need a faraway control
(2)、Which is the function of the camera in the robot?
A、Detecting trapped people B、Dealing with harmful gases C、Providing oxygen and water D、Sending goods to the quake area
(3)、Which of the following is TRUE about the robot?
A、It weighs about 30 kilos B、It has not been put into use C、It works only in the daytime D、It entered production years ago
(4)、What does the passage mainly tell us?
A、Earthquake rescue B、The development of robots C、Tests on a new robot D、An introduction to a robot

A US high school with only 200 students is producing some of the world's best technology. 

Students at this school made cars with improved fuel efficiency(燃油效率) and other inventions, too. And now, the students are designing a washing machine for outer space. They hope it will be accepted by NASA or us. 

NASA asked for ideas through ifs HUNCH program, which is short for "High School United with NASA to Create Hardware". Braham Area High School is one of the 100 schools in the program. 

The challenge is to come up with a good way to wash clothes on long-time space tasks, where air and water don't mix and soap can't be used. On shorter space tasks, astronauts simply throw away their dirty clothes. For longer tasks, a different solution is needed. 

The team has already built a system using a series of pumps(泵) and vacuum chambers(真空室),but NASA were afraid that it might not be durable(耐用的). 

The washing machine isn't the only NASA project Brahma students are working on. They're also designing and building a track system to hold equipment. NASA said it plans to use their system. 

They're also designing an automated(自动化的) feeding system for space mice. NASA regularly takes mice into space as test subjects. 

"To get a kid to do something that they never thought they could do, that's really great! " said Luke Becker, the school's technology teacher. "There are kids who never planned to do anything in technology until they had these chances. "
