2026年初中必刷题七年级英语上册沪教版第61页答案
[2026广东广州调研]
Introduction
Rockets are like big engines that help push(推)things in a forward(向前)or upward direction. We use them to launch spaceships into space or to shoot(射出)fireworks into the sky.
How Rockets Work
Rockets work by burning fuel(燃烧燃料). When the fuel burns, it produces a kind of hot gas. This gas shoots out of the back of the rocket and pushes it forward.
History
The Chinese were the first to make rockets, back in the 1200s. They filled bamboos with a special kind of powder(火药). This powder burnt very quickly and produced enough gas to shoot the rocket into the air. Later, in the 1700s, people started making rockets out of metal(金属).
In the late 1800s, a Russian scientist, Konstantin Tsiolkovsky, was the first person to design a liquid(液体的)fuel rocket, but he didn't build one. An American engineer named Robert Goddard was the first person to do this in 1926. In 1957, the Soviet Union(苏联)used a rocket to launch the world's first space satellite, Sputnik-1. Since then, many countries have used rockets to send things into space.

答案

1. B 推理判断题。通读全文可知,本文主要讲述了火箭的作用和火箭如何运作,以及火箭的发展历史。故选 B 项。
2. D 细节理解题。根据“When the fuel burns, it produces a kind of hot gas. This gas shoots out of the back of the rocket and pushes it forward.”可知,燃料燃烧时,会产生一种热的气体,这种气体从火箭后部射出,推动火箭前进。故选 D 项。
3. A 细节理解题。根据“The Chinese were the first to make rockets, back in the 1200s.”可知,早在 13 世纪,中国人就率先制造了火箭。故选 A 项。
4. D 细节理解题。根据“In the late 1800s, a Russian scientist, Konstantin Tsiolkovsky, was the first person to design a liquid fuel rocket, but he didn't build one.”可知,在 19 世纪末,俄罗斯科学家康斯坦丁·齐奥尔科夫斯基是第一个设计液体燃料火箭的人,但他没有建造火箭。故选 D 项。
5. D 细节理解题。根据“Konstantin Tsiolkovsky, was the first person to design a liquid fuel rocket, but he didn't build one. An American engineer named Robert Goddard was the first person to do this in 1926.”可知,罗伯特·戈达德在 1926 年的时候建造了第一枚使用液体燃料的火箭。故选 D 项。
