4 the sewing machine was invented, sewing by hand was hard work. Elias Howe decided to design a machine to make the sewing easy and quick. 5 he made some progress, he met a problem. It seemed 6 to get the thread (线) to run around the needle (针) without any problems.
One day, he was tired, and slept badly. Then he had a 7 . In the dream he was 8 by a king. The king ordered him to build a perfect sewing machine, 9 he would be killed. When he tried to do so, Howe met the same problem. The king was so angry that he ordered his soldiers 10 Howe with a spear (长矛).
Just before the spear stuck to his body, suddenly he noticed something. There was a hole in the tip (尖端) of the spear. Howe woke up from the dream. And he 11 that he found the way to solve the problem. He should make it run through a small hole in the center of the needle 12 getting the thread to run around the needle. A simple idea finally came into Howe’s mind. 13 , he invented the first sewing machine.
Like Howe, many scientists found the way to solve their problems 14 this way. Thomas Edison said his best idea came into him in dreams. So 15 Albert Einstein.

Solar eclipses (日食) and lunar eclipses are fascinating events in space. During a solar eclipse, the Moon passes between the Earth and the Sun, making the Moon’s shadow (影子) fall on the Earth. If the Moon covers the Sun completely, it is called a total (全) solar eclipse. Sometimes, the Moon does not cover the Sun completely, and we see a ring around the Sun. This is called an annular (环形的) solar eclipse.
During a lunar eclipse, the Earth comes between the Sun and the Moon, leaving its shadow on the Moon. Depending on how much of the Earth’s shadow falls on the Moon, we can have different kinds of lunar eclipses: total, partial, or penumbral (半影月食).
To understand when these eclipses happen, we need to know where the Earth, the Moon, and the Sun are positioned in space. For example, solar eclipses usually happen when the Moon is closest to the Earth, during the new moon. Lunar eclipses happen during the full moon. Compared to solar eclipses, lunar eclipses are much more often seen on the Earth.
In Chinese stories from long ago, people thought dragons caused solar eclipses. They believed that two dragons fought and blew up storms which led to an eclipse. To make the dragons stop fighting and bring back light, people would play loud music and set off fireworks.
There is also another story about Tiangou, the dog of a god, trying to eat the Moon during a lunar eclipse. To save the Moon, people would make loud noises like playing the drums and shouting to scare away Tiangou.
These old tales show how people explained eclipses before scientists understood them. Now we know the real reasons behind these events, but the stories still remind us of how humans wanted to understand space.

A.placed B.processed C.fallen D.broken
24.According to Chinese folk stories, what causes a lunar eclipse
A.Two dragons blowing up storms. B.A dog trying to eat the Moon.
C.Two dragons fighting with each other. D.A dog running after the Moon.
25.Where can you learn more about eclipses

The Chinese-made aircraft (国产飞机) are playing an important role in protecting the country’s green mountains. Many models of newly developed large unmanned aerial vehicles (UAVs) (无人机) are showing their ability to protect the environment. In recent years, they have been used to put out forest fires and do other dangerous tasks (任务).
In mid-March 2024, Yajiang County in Sichuan Province faced a challenging spring when a serious forest fire happened. However, the situation changed quickly as the new aircraft were used to support firefighting (消防). The aircraft played a key role in finding what causes the fire and understanding its size. The UAVs gave real-time heat pictures and maps, helping plan the firefighting efforts. At the same time, the fixed-wing (固定翼) aircraft dropped water on certain areas. It stopped the fire and saved more of the forest. This was the first time that China had used large UAVs to carry out some tasks, like putting out forest fires. The move showed the advantages (优点) of these new aircraft and provided a new way to stay away from disasters (灾害).
These new aircraft were also used for other tasks. MA-60 aircraft have been used not only for firefighting, but also for spring drought (干旱). In the spring of 2024, they increased the rounds of rainfall (降雨轮次) in Shaanxi Province. They have also played a key role in facing the challenges of the weather.
Clear waters and green mountains are not only natural wealth but also social wealth. As the technology improves, more Chinese-made aircraft will be developed in the future. They will reduce the influence of natural disasters on the country and protect people’s lives and wealth.
26.In recent years, the Chinese-made aircraft have been used for dealing with ________.
① forest fires. ② technology. ③ spring drought. ④ social wealth.
A.①②. B.①③. C.②④. D.③④.
27.What do we know about the UAVs in the task of Yajiang according to the passage
A.They provided real-time heat pictures and maps.
B.They sent firefighters (消防员) to the fire place.
C.They acted as communication tools among firefighters.
D.They watered the place to prevent the fire from spreading.
28.How does the writer support his idea in Paragraph 3
A.By listing numbers. B.By comparing facts. C.By giving an example. D.By reporting results.
29.Which is the right structure of the passage
(①= Paragraph 1 ②= Paragraph 2,…)
A. B. C. D.
30.What’s the writer’s purpose of writing the passage
A.To show some models of newly developed large UAVs.

China’s FAST, the world’s largest radio telescope, is in Guizhou Province.
Imagine a giant pan in a big, round hole in Guizhou. This isn’t just any pan; it’s China’s 500-meter Aperture Spherical Radio Telescope (500米口径球面射电望远镜), or FAST for short. People also call it the “Sky Eye”.
FAST is the world’s biggest radio telescope. It’s so big that it covers an area as large as 30 soccer fields! It was finished in 2016 and started working in 2020.
One of FAST’s main jobs is to find pulsars, which are like the “GPS of space”. Pulsars can help people find their way back to Earth if they travel to the moon or Mars. So far, FAST has discovered over 800 pulsars (脉冲星)!
FAST is also amazing at finding signals (信号) from space. It’s even better at this than the second biggest telescope in the world. It can “see” things that are 13.7 billion light years away! This means if you made a phone call from the moon, FAST could hear it very clearly.
Since March 2021, China has opened FAST to the whole world. It has helped scientists from 16 countries and regions by giving them nearly 6,400 hours of observation (观测) time.
The team that looks after FAST is always trying to make it better. They’ve introduced five smart robots to help clean, fix, and change parts of the telescope. This makes it much easier to take care of and use.
So, that’s FAST, the world’s biggest and most amazing radio telescope!
