Do you know any famous museums in the world? Here are three famous museums in different countries.

Social media (媒体) is a big part of most people’s lives. There are social apps and sites like WeChat and Sina Weibo, as well as video apps like Douyin and Kuaishou. How do you behave when you use these apps?

Recently researchers at the University of Sussex, UK, studied social media users ranging from 10 to 15 years old. They found that they can be divided into four personality types.

Geeks (极客)

Geeks are active social media users, but they find it much more difficult to deal with the life in the real world. Most of them are boys who like playing computer games and making music and videos. They often post creative works online, using fake (假的) names. In fact, they should avoid spending too much time on the Internet.

Internet celebrities

Internet celebrities like sharing as well, but they are much more visible (看得见的) than geeks. They might become well-known for their singing or dancing. But many of them, especially teenagers, share almost every side of their lives in order to own more fans. Being a teenage Internet celebrity can sometimes cause problems in the real world.

Lurkers (潜伏者)

The first two groups are lucky to find a place to show their talent. But most teenagers fall into the third type—“lurkers”, or people who are neither too active nor visible. This group prefers WeChat over Sina Weibo, as WeChat has private groups. They can’t express themselves well but at least they make sure to protect their personal information.

Victims (受害者)

Victims don’t have enough knowledge to keep themselves safe online. Their personal information can be made public and cause problems for them. To avoid being a victim, you should check your personal settings on social media. “Friends only” is a good choice for your posts. Don’t share your personal information.

Nothing is too hard if you put your heart into it. Many students always complain (抱怨) that they always     31     (have) too many difficulties in English, so many of them stop     32     (study) it halfway. Here is a story about my English teacher.

About 35 years ago, when my English teacher was a middle school student, he didn’t like English. He     33     (think) English was boring and useless. And he decided     34     (give) it up. His mother, who was a farmer and had never studied English, noticed this and wanted to do what she could to help him. One day, to his surprise, when he came back home, his mother     35     (write) something with a stick on the ground. So he asked, “Mom, what     36     you ________ (do)?” Then he saw five English words. Each day after that, his mom went on doing the same thing. How busy his mom was! But she could memorize five words every day! What’s more, his mom did all she     37     (do) to save money in order to buy a radio. Later, mom often learned English over the radio together with him. My teacher     38     (encourage) by his mother and soon he loved English and improved his English quickly.

“I believe miracles (奇迹)     39     (happen) if you don’t give up trying. Although you     40     (fail) one hundred times, you may succeed when you try for the 101st time.

Once upon a time, there lived a wise man. Everyone looked up to him. His son, however, was very l    41     and did nothing all day.

The wise man was worried about his son’s future. One day he said to his son, “I want you to go to find some treasure.” Then he gave his son a bag. I    42     the bag were clothes, some food, a little money and a map.

The son set out on his long journey the next day. He had to travel across forests, rivers and mountains. Along the way, he met a lot of people. They h    43     him when he was in trouble. He also came across robbers (强盗). He saw the beauty of nature and experienced d    44     kinds of weather.

F    45    , after a long year, he reached the treasure’s location. He spent two days looking for the treasure, but found n    46    .

Disappointed, he began to go back home. On his way back, he learned to hunt (打猎) and make meals. He had to fix his own clothes himself. He met the s    47     people who had helped him earlier. This time, he stayed and helped them.

When he reached home, he said s    48     to his father for not finding the treasure. “There wasn’t any treasure in the place, my son, b    49     I think you have found your life’s true purpose,” the father answered with a s    50    .
