First of all, there’s the golden rule of the Internet: If you see or read something that makes you feel uncomfortable,     1     immediately. Don’t     2     or click on anything. Second,     3    . Don’t     4     your address or phone number. Someone might use the information to steal your identity. Identity theft is a common and serious problem. Third, be polite. Being online is no excuse for being rude, and you don’t want to     5     for a troll or cyberbully.

There is so much more to learn about the interesting history and culture of the United Kingdom. Studying the history of the country will make your visit     6    . The capital city London is a great place to start, as it is an     7     that has a history dating     8     back to Roman times. There are countless historic sites to explore, and lots of museums with ancient relics from all over the UK. The UK is     9     of history and modern culture, with both new and old traditions. If you     10    , you will be surprised to find that you can see both its past and its present.

As we live in social groups, there are many b    1     of friendship that we can enjoy. G    2     speaking, close friendships have three “fruits”: they may c    3     the heart, advise the head and help us a    4     the goals we set for ourselves. Through friendship, we can become happier, wiser and more s    5     humans.

Economic development is necessary if we want to improve s    1    . There comes a time w    2     the old must give way to the new, and it is not possible to p    3     everything from our past as we move towards the future. Finding and keeping the right b     4     between progress and the protection of cultural sites can be a big challenge.

Big challenges, however, can sometimes lead to great s    5    . In the 1950s, the Egyptian government wanted to build a new dam across the Nile in order to control floods, produce electricity, and s     6     water to more farmers in the area. But the p    7     led to protests. Water from the dam would likely damage a number of temples and d    8     cultural relics that were an important part of Egypt’s cultural h    9    . After listening to the scientists who had studied the problem and citizens who lived near the dam, the government t     10     to the United Nations for help in 1959.

Several years ago, when I was working in a school, a thin boy showed up in my office. It was David. His head teacher had referred him to me. “This boy has lost his family,“ he wrote. “He is very sad and r    1     to talk to others, and I'm very w    2     about him. Can you help?”

Sometimes the best thing one can do is to listen openly and patiently.

The first two times we met, David didn't say a word. He sat there, only looking up to look at the children's drawings on the wall behind me. I suggested we play a game of chess. He n    3    . After that, he played chess with me every Wednesday afternoon—in complete s    4    , without a word.

Usually, he arrived earlier than agreed, took the chess b    5    and pieces from the shelf and began setting them up before I even got a chance to sit down. It seemed as if he e    6     my company. But why did he never look at me?

"Perhaps he simply needs someone to s    7     his pain with, "I thought. Perhaps he sensed that I respect his suffering." Some months later, when we were playing chess, he looked up at me suddenly.

"It's your t    8    ,” he said.

After that day, David started talking. He got friends in school and joined a bicycle club. Now he has really started to live his own life.

Maybe I gave David something. But I also learned that one, w    9     any words, can reach out to another person. All it takes is a hug, a shoulder to cry on, a friendly touch, and an ear for the w    10     heart.

Ben, 17, is a member of their school basketball team. He is crazy     1     basketball and pretty good at it but they    2     (lose) their last match. In Ben’s opinion, their point guard was     3     (blame).     4     (disappoint) by his behaviour, Ben told this to his best friend. However, his best friend told everyone else     5     he’d said. Ben didn’t know what to do, so he asked Agony Aunt for help.

As far as Agony Aunt is concerned, it is     6     (main) his friend’s loose lips that make the situation     7     (bad). But it’s partly Ben’s fault. She suggests that Ben should apologise to his teammate. Secondly, Ben should tell his friend that he is     8     (anger) with him for repeating what he said and making the situation worse,     9     that he wants to move on. Thirdly, Ben should think about his own behaviour and always remember: think first, speak later. If he feels one of his     10     (teammate) isn’t pulling their weight, he will raise his concerns in a professional way with his team coach.

Yuan Longping, known     1     the “father of hybrid rice”, is one of China’s most famous scientists. Yet, he     2     himself a farmer because he continually works the     3     in his research. Indeed, his slim but    4     body is just like that of millions of Chinese farmers, to whom he has     5     his life.

Yuan Longping was born in 1930 in Beijing. His parents wanted him to pursue a career in science or medicine. However,     6     concerned him most was that farmers often had poor     7     and sometimes even had a serious     8     of food to eat. To     9     this crisis, he chose to study agriculture and received an     10     at Southwest Agricultural College in Chongqing.

Festivals are an important part of society. They reflect people’s wishes, beliefs, faiths and    1    . They are    2     allow us to relax and enjoy life, and forget about our work for a little while. They help us understand where we came from, who we are, and     3    . And if you study festivals carefully, you may be surprised to find that     4     actually have a lot in common after all.

Imagine having the o    1     to sing together with hundreds of other people while you are at home alone. You can do this in a virtual choir. Virtual choir members record themselves while they p    2     alone on video. These videos are uploaded o    3     the Internet, and then they are put together into the video that you can see online—a virtual choir. Anyone can take part in a virtual choir from anywhere—all you need is a video camera and an Internet c    4    . You do not even need a s    5    . A virtual choir helps connect o    6     people together. Many people do not have close friends or contacts who have the same interest in m    7    . Many others do not have the chance to join a local choir. A virtual choir e    8     them to add their voices to those of other individuals and become part of the global community. It has p    9     to be a positive influence on the lives of many people. A    10     one virtual choir member said, “Music helps me to forget my problems. With music, I become someone else.”
