1、 阅读短文,回答问题
You know that dust storms (沙尘暴) happen on Earth. But do you know they can happen on Mars, too? Now, Chinese scientists have a powerful new tool called the GoMars model. It can simulate (模拟) the dust cycle on the Red Planet just like a computer.
According to Xinhua News, Mars is like Earth's close "sister" planet. Studying it could tell us about how life began, and one day, it might even become a future home for human beings. However, we still don't know much about the weather on Mars, especially its dust cycle. This cycle is very complicated (复杂的) because it is about the dust, the thin air, and wind on the ground all working together. Big dust storms can cover the sky, making it hard for rovers (探测器) to work and making challenges for future space tasks.____
The GoMars model first came out in 2023. It's very powerful because it can simulate the movement of not just dust, but also water and carbon dioxide (CO2) on Mars. In a new study, scientists used it to study how dust moves over a very long time—more than 100 years. The model also made an interesting discovery: dust activity on Mars is the strongest between 12 p.m. and 1 p.m. local time.
This research is very important. It helps scientists understand real-time weather on Mars, almost like having a weather forecast (预报) for another planet. In the future, when taikonauts land on Mars, this knowledge will help them pick safer times and places to explore, getting us ready to learn more about our "red neighbor".
(1)、How does the writer start the passage?A、By listing numbers. B、By giving an example. C、By asking a question. D、By expressing feelings.(2)、What can the GoMars model do?A、Stop dust storms on Mars. B、Bring water and CO2 to Mars. C、Help taikonauts land on Mars tomorrow. D、Simulate the movement of dust, water and CO2 on Mars.(3)、Which sentence can best fill in ____?A、Besides, Mars is very cold at night. B、That's why we need good tools to study them. C、However, Mars is very far from Earth. D、As a result, scientists want to live on Mars soon.(4)、According to the text, when is dust activity the strongest on Mars?A、In the evening. B、Between 12 p. m. and 1 p. m. local time. C、Between 12 a. m. and 1 a. m. local time. D、Scientists are still not sure.(5)、Which of the following is the best title for this passage?A、A New Tool for Studying Mars' Dust Storms B、Creative Weather Forecasts on Earth C、How to Become a Spaceman on Mars D、Water and CO2 on Our Neighbor Planet -

Believe it or not, the day when you can go to the Moon to take a trip is coming soon. You can go into space by space shuttle (航天飞机).

The Moon moves more 8 than the Earth, so one day on the Moon is as long as about 27 days on the Earth. What could you do in such 9 days and nights and in a silent world? You can take photos of the beautiful stars and the faraway Earth, but you can't hear any sounds because there is no air to 10 sound. It never rains on the Moon and everything on the Moon is 11 . There are no trees or other living things of any kind. The ground is covered with soft dust (灰尘) that feels 12 under your feet.
There is nothing to do there for fun. The Earth is a better 13 to live on with its blue sky, green trees and lovely animals. But scientists are trying to make the best use of the Moon. They hope to build a(n) 14 station there in the future, so more people can visit the Moon and learn about it. For now, this wonderful trip is just a dream for many, but who knows? With the development of science and technology, it may 15 true sooner than we think.
