A
With the development of science, more and more students don't like taking notes by hand. Instead, they use digital cameras to take pictures of the words that their teachers write on the blackboard or record what their teachers say in class.
The children might think there are too many notes to take or their teachers write or speak so fast that they can't take more specific notes. They are trying to find ways to make things easier, so they use digital cameras. In fact, children are very clever to make use of technology.
But do digital cameras really make taking notes easier
Not really. Before you read notes from digital cameras, there are a lot of things you have to do. To begin with, you have to find a computer. Then you need to copy the photos into the computer. Next, you have to find a printer(打印机) to print the photos. Another thing is that you can't hear the sound from the digital cameras clearly because there is usually lots of noise. You will have to listen to it slowly several times before you understand everything.
In fact, taking notes by hand has many advantages. For example, it can help you remember and understand what you are learning. In order to save time, you can choose the most important things or the things you don't understand to write down. You don't have to write down everything.
Don't be afraid to take notes by hand. It's really an effective(有效的) way.

Frank and his brother Jack lived near the ocean. Frank was outgoing while Jack was shy. They liked doing different things. Frank was famous for organizing games of beach volleyball, football, and any other sport imaginable. Jack preferred to draw, paint, or build sandcastles（沙堡）.

At least 30 people were building a city of sandcastles, and everyone was chatting and laughing and working together! It was the most beautiful thing he had seen on the beach.
"I guess you've proved me wrong," Frank said. "You should make this sandcastle day a yearly tradition!" Handing Frank a shovel（铲子）with smile, Jack got started together with his brother on their super creation in the sand.

Have you ever heard of India It is said that from old times, India has been a good friend to China. It is an interesting and mysterious country with a long history. Around 2，000 BC, Indian civilization was born. It is one of the four oldest civilizations in the world.
India is also the birthplace of Buddhism(佛教). A famous Chinese novel, Journey to the West, is about a Chinese monk who tried very hard to learn about Buddhism from India. The book comes from a true story. Xuanzang, a Buddhist monk, was sent to India by the emperor of the Tang Dynasty. After many years, he brought back lots of Buddhist books. The name “India” was first used by Xuanzang in his works.
Today, religion is still an important part of Indian culture. There are many religions there. Most Indian people believe in Hinduism(印度教). In India, cows are very special animals because Hinduism says they are holy, so Indians don't sell or eat beef.
Like China, India is a developing country with a large population. It has about 1.03 billion people compared to China's 1.3 billion. More than two thirds of the Indians still live a poor life in the countryside. India has no birth control so its population is growing fast. By 2030, India could even have more people than China.
Hindi(印地语) is the mother tongue of Indian people. But Britain occupied India in 1757 and stayed there until 1947. Because of this, English slowly became the other official language.

Do you know which social app Chinese young people use a lot now 36 Some users use Tik Tok ( 抖音) and Kuaishou (快手）. They think it is fun to share short videos about their lives, while others have other purposes as well.
A l2-year- old user named Elsa has about 2.7 million fans on Tik Tok. The girl has shared videos about her dancing studies since last July. 37 “I feel really glad to share happiness with people by short videos," said Elsa.
As some videos are about the latest news, a group of users depend on them to get information. To some other users, they have a different purpose. “Because I can’t spend many hours watching a whole video and I’m not a very patient person, 38 I prefer to watch short videos of wonderful parts in programs," said Wang Zhihao.
39 “Killing time is the main reason for me to watch the short videos, but many are almost the same, so I think it is a waste of time. What’s more, I really don’t like the videos which show strange even dangerous things," said Wen Nan, another college student.
Recently, something else has happened. Some videos are telling people what products are worth buying. 40 So they should think twice. Some short videos even sell bad products, but these sellers won’t let you get your money back.
根据短文内容，把A-E五个句子填入空缺处，使短文内容完整、正确，并将其标号填写在下面题号后的横线上。
A．I don’t like waiting for a program to end.
B．“Short videos" are certainly the most popular.
C．But after they buy the products, they may regret soon.
D．One of the videos won her about one million fans.
E．However, some young Chinese feel bored with some short videos.

45．句意：只要天气好，可以看到星星，这种方法在夜间效果很好。下文“But it didn't work so well during the rest of the time”，根据but句意转折可知，此处指“天气好时这种方法在夜间效果很好”；备选词well“好地”符合语境。故填well。
46．句意：只要天气好，可以看到星星，这种方法在夜间效果很好。根据“as long as the weather was good”可知，此处指“只要天气好，可以看到星星”；备选词see“看见”符合语境，the stars与see是被动关系，所以，填过去分词与“could be”构成含有情态动词的被动语态；故填seen。
47．句意：但在剩下的时间里，效果并不好。上文“This method worked well at night as long as the weather was good and the stars could be seen”，根据but句意转折，可知此处指“在剩下的时间里，效果并不好”；备选词during“在……期间”符合语境；故填during。
48．句意：我们可以在任何时间、任何地点、任何天气使用它来查明我们的位置。上文“只有天气好才能看到星星辨别位置”，可知此处指“在任何时间、任何地点、任何天气使用GPS来查明我们的位置”；备选词weather“天气”符合语境。故填weather。
49．句意：它也可以用来研究地球的形状。上文“We can use it at any time, in any place and in any weather to find out our position.”讲述GPS的一种功能，可知下文说明GPS的另一种功能，指“GPS也可以用来研究地球的形状”；备选词also“也”符合语境。故填also。
50．句意：全球定位系统是一个伟大的发明，它帮助我们探索我们的星球和发现我们在哪里。本文讲述GPS的功能：可以在任何时间、任何地点、任何天气使用它来查明我们的位置、用来研究地球的形状；此处是段落的总述句，指“GPS是一个伟大的发明”。备选词invention“发明”符合语境。故填invention。

【分析】本文介绍了牛仔裤。牛仔裤最开始是为工人设计的，材料是做帐篷用的布。现在牛仔裤的面料有了很大的改变，牛仔裤也在全世界流行起来。
51．句意：第一条牛仔裤生产于1855年。根据“in 1855”可知句子时态为一般过去时；由于主语“jeans 牛仔裤”是被生产，所以谓语动词要用一般过去时的被动语态结构，即“was/were+动词过去分词”结构，句中已有过去分词produced，“jeans”是复数，所以be动词用were，故填were。
52．句意：那时候，他们不叫牛仔裤，他们只是为工人设计的耐穿的裤子。“hard-wearing”表示“耐穿的”，工人需要耐穿的衣服，所以耐穿的“jeans”是为工人设计的，design for为固定搭配，表示“为……设计”，故填for。
53．句意：这种布通常用来做帐篷。根据“This kind of cloth usually was used for...tents.”可知，布是用来制作帐篷，动词make表示“制作”，符合语境；由于for是介词，介词后接动词的ing形式，故填making。
54．句意：它们不仅是为工人设计的，也是为青少年和妇女设计的。not only ... but also ... 为固定短语，表示“不仅……还……”，故填but。
55．句意：后来牛仔裤风靡全球。all over the world为固定短语，表示“全球，全世界”，故填the。
