Do you have any online classes? It is possible to take classes at home. All you need is a computer and a headset.
However, most students don't seem to like online classes. According to a recent survey, only 33 percent of students would take such classes. Over 1,500 students from 10 cities took the survey.
Many students said it is hard to focus on studying while taking online classes.

It's harder to always stay focused," she said.
Lian prepares a lot before taking her classes to make sure she will pay attention. She also pushes herself to communicate with teachers. Students can come up with or answer questions while taking online classes.
But Wen Jiayi, 14, at the Yucai Middle School Attached to Chengdu No 7 High School, thinks online interaction (互动)isn't enough.“The online teachers don't really get to know me. When I don't hand in homework, all I get is a short message instead of real concern (关心),” she said.
However, online classes still have other advantages.“It saves time and money compared to taking offline classes. Also, if I don't understand some parts of a lesson, I can watch it over again," Lian said.

A．About 400. B．About 500. C．About 600. D．About 700.

A．She can’t follow the teachers.
B．The teachers can’t answer her problems.
C．The teachers online care less than offline.
D．She can’t finish her homework in time.
45．What’s this passage about?
A．The writer’s view on online classes.
B．A survey about online classes.
C．The future development of online classes.
D．How to take online classes.


A big sandstorm hit northern China on March 15, 2021. It covered many cities with thick clouds of yellow dust (尘土).
The storm, which came from Mongolia (蒙古国), was the largest sandstorm to hit China in the past 10 years. Many flights and classes were canceled because the visibility (能见度) was lower than 500 meters.
The storm was the result of warm and dry weather in the area, together with the strong winds from Mongolia. “There has been little rainfall so far this spring and the temperature is rising. So now is a worrying time for sandstorms,” said an expert from Beijing.

In recent years, sandstorms haven’t been as common in northern China as before. The land with desertification (荒漠化) has been falling by 7,585 km2 per year in China, and the area of sandy land has been decreasing by 1,284 km2 a year. This is thanks to China’s Three-North Shelter Forest Program (TNSFP, 三北防护林工程) which started in the 1970s. Millions of trees have been planted in northern China to prevent sandstorms and protect the environment.
Besides, China has a color-graded warming system for sandstorms (as shown in the picture), with red meaning the most serious, followed by orange, yellow, blue and green. Therefore, people would have time to get prepared for the sandstorm.
46．According to the passage, the sandstorm in March ________.
A．covered many cities with rain B．came from Northern China
C．has been the biggest one since 2011 D．improved the visibility to 500m
47．Paragraph 3 mainly talks about the ________ of sandstorm.
A．results B．causes C．history D．areas
48．The underlined word “decreasing” in Paragraph 4 means ________.
A．going down B．rising up C．taking up D．running out
49．If the visibility in your city is 400m, a(n) ________ warning will be given out.
A．red B．orange C．yellow D．blue
50．The passage introduces TNSFP and the warning system to show ________.
A．where the serious sandstorms come from
B．why people should protect the environment
C．how to protect ourselves during sandstorms
D．what China has done to fight against sandstorms


八、阅读回答问题
Since early 2020, the use of mask (口罩) has increased greatly. Sadly, lots of used masks ended up in our ocean.
Single-used masks are mainly made of plastic. When they enter the ocean as litter, they will take as long as 450 years to break down. Straps (带子) of masks pose an entanglement (缠绕) risk for wildlife. In addition, masks can easily be mistaken for food and eaten by wildlife.
What can be done to help? Since most masks are made of several materials, it’s difficult to recycle them. Therefore, many people are calling for masks made of a single material. Degradable (可降解的) or reusable masks are also good choices. More importantly, the straps of masks should be cut off to prevent entanglement risks for wildlife.
Government policy is also important. Creating an effective disposal (处理) system is as important as letting the public know the importance of proper disposal of used masks. What’s more, it would be helpful to encourage technological development in producing reusable or degradable masks.
51．How long will it take for a single-used mask to break down in the ocean?

52．Why might some animals eat masks?

53．What should we do with mask straps?

54．How many suggestions for the government are mentioned?

55．What does the passage mainly talk about?



九、短文语境提示填空
阅读短文，根据语篇意义填空，使短文通顺，意思完整，每空限填一词。
With the environment becoming worse and worse, more and more people realize the importance of protecting the environment. But there are still some people paying less 56 to it. They are still doing something harmful to the environment. Last Sunday I went to the Plant Garden to enjoy 57 . When I stepped into the gate of the garden, I felt comfortable at first because I could breathe the fresh air and enjoy the beautiful flowers and trees. But to my 58 , I saw a man lying in a sleep net hanging 59 two trees. I thought this kind of behavior would hurt the trees. How could he make money by hurting the trees like this? Without trees, how could we get the fresh air? I don’t know how to express my anger. I think 60 is our duty to protect the environment. So something must be done to stop this kind of behavior.

45．主旨大意题。根据第二段中“According to a recent survey”及后面围绕学生线上课程发表的观点可知，本文主要是关于线上课程的调查。故选B。
【点睛】本题的第3小题是词义猜测题。词义猜测题是阅读理解中常见的一种题型，所猜测词汇可以是生词，也可以是熟词新义，还可以是人称代词的指代内容。词义猜测题主要考查考生根据上下文推测词义和语义的能力，突出考查对语境的分析和把握能力。本题可以利用下文语境来猜测词意。猜测任何词义都离不开上下文，所以要借助上下文对需要猜测的词或短语进行合乎逻辑的推测。

47．段落大意题。根据“The storm was the result of warm and dry weather in the area, together with the strong winds from Mongolia.”可知，本段主要介绍了沙尘暴的原因，故选B。

49．推理判断题。根据图片可知，能见度为400米属于heavy sandstorm，根据“ red meaning the most serious, followed by orange, yellow, blue and green”可知，应该用橙色表示，故选B。
50．推理判断题。根据“This is thanks to China’s Three-North Shelter Forest Program (TNSFP, 三北防护林工程) which started in the 1970s. Millions of trees have been planted in northern China to prevent sandstorms and protect the environment.”可知，三北防护林工程始于1970年代，为了防止沙尘暴和保护环境，中国北方种植了数百万棵树。所以介绍三北防护林工程是为了展示中国为抗击沙尘暴所做的努力。故选D。

58．句意：但令我惊讶的是，我看到一个人躺在两棵树之间的睡眠网里。根据下文“How could he make money by hurting the trees like this?”可知我不能理解，他怎么能通过这样伤害树木来赚钱，说明我比较惊讶，to my surprise“令我惊讶的是”，故填surprise。

66．例文
It’s really wonderful news that the policy of “Double Reduction” has been carried out. However, students have to deal with the new challenge of making the best of their time after school. Here are my suggestions.
First of all, we should make good use of the time at school. We can listen to our teachers carefully and take notes of key points in class. And it’s also necessary to ask for help whenever we have trouble in our study. For example, we can discuss the problems with our classmates or turn to our teacher after class. Secondly, finish homework effectively, which means we should develop the ability of concentrating on what we are doing. Thirdly, we are supposed to take up some healthy and meaningful hobbies to enrich our after-school life. Last but not least, we can do some housework or volunteer work to get some useful life skills.
I hope that we will enjoy a happier life and grow into a better person with the policy successfully carried out.
