North AfricaAfrica is the second largest continent on Earth. It is about 8,000 kilometers long from north to south. It can be divided into three major regions: northern Africa, central Africa, and southern Africa. 1 Africa is separated from Europe by the Mediterranean Sea (地中海). It is connected to Asia in the east. For this reason, it has been easy for people from Europe, Asia and other areas to come to North Africa. 2 Most of North Africa is covered by the Sahara Desert. 3 There is little rainfall here. The few people who live in the desert live in oases (绿洲). The valley of the Nile River forms one of the oases that stretch across the desert in the east. Many North African nations have a very important resource. They have large deposits of petroleum. 4 In return, these nations receive a lot of money. They are spending some of this money to make life better for their people.Egypt is an important nation in North Africa. 5 It has served as a bridge between Africa and Asia. People from many nations have passed through Egypt. Today, it controls the Suez Canal. The canal connects the Mediterranean Sea and the Red Sea. It is important for ships traveling between nations in Europe and Asia.

Little Steps, Big Reward① More than 145 million Americans take walking as part of their exercise, according to a recent report. That's 15 million more people walking than last year. Many places in America have reported an increase in walking. But most of the walkers are found in big cities like New York.② Despite the increase in walking, only about 30% of Americans say they have at least 3 hours to take exercise a week. Our society has been conditioned to be inactive. People rely on modern conveniences and become lazy. The inactive lifestyle has a negative aspect. We are more likely to be in poor health like overweight, which will threaten our life span. That's where walking comes in.③ Walking is the best way to improve our health. Just 30 minutes of regular quick walking can help lose weight. At the same time, it can help lower the risk of heart disease and some cancers, and improve our blood pressure. If 30 minutes is too much, we may divide it into three 10-minute parts during the day. Most of us can find 10 minutes if we really try.④ Walking requires only a pair of shoes and suits any schedules. Keep a pair of sport shoes at work. If you have a few minutes of free time, make use of them to take a quick walk. Even if you go to a health club several times a week, you can still look for ways to be active while at work. It may be walking downstairs for a direct talk rather than sending an email.⑤ Small efforts can make a big difference. But the hardest part for us is getting started. It's usually like this. When people get to a comfort level of walking for 10 minutes, they might think about trying 11 minutes. That first step is really worthy.1.Paragraph 1:2.Paragraph 2:3.Paragraph 3:4.Paragraph 4:5.Paragraph 5:

Universal GesturesGestures for victory, defeat and stress are almost the same in all countries.On the front page of a newspaper we often see the picture of people holding their head in shock. People put their hands on their head or over their mouth when they look on a scene with shock or horror.Chris Ulrich is an expert on body language. He said that covering your mouth or putting your hands on your head helps make you feel safer from a perceived threat. By covering part of your face you can feel hidden from the shocking event. Additionally these reactions can help a person comfort himself through touch. Ulrich said it is a self comforting gesture to help people in the moment.In times of strong anxiety, people will twist their hands to calm themselves. Ulrich said it is a reaction people often have when they are in front of an audience or nervous. "It's a comfort for them that they'll get through it," said Ulrich. He relates that gesture to a parent trying to calm a child.Most athletes react to victories or defeats with specific behaviors. A 2008 study examined pictures of judo (柔道) competitors during the 2008 Olympic Games. They were from different countries, but they showed similar behaviors when they won a match. The winners would throw their head back or raise their hands in triumph. Ulrich said these victory behaviors are a way winners "explode" out and take up more space.However, if an athlete suffers a loss, he will act in a way that makes him physically smaller, such as hanging his head. "When you lose, you want to disappear," said Ulrich. The study also found that the judo competitors had the same behavior when they lost.1. People put their hands over their mouth to___.2. People tend to twist their hands when they are_.3. In Paragraph 4, "that gesture" refers to_.4. Judo winners often act in a way that makes them_.5. The judo losers would___.

Who Is James Bond?The latest Bond film is an enormous box-office (票房) hit. But who is James Bond? Where does he come from? Author Ian Fleming, the creator of James Bond, told us something about the origins of the world's most famous secret agent. In the first Bond novel, Ian Fleming told us that James Bond was the son of a Scottish father and an Asian mother. But perhaps this was not really true. The title of the 19th Bond film, “The World Is Not Enough,” was based on the Latin motto of the Bond family, which is mentioned in one of the early novels. However, it now appears that the motto is not that of the Scottish Bonds, but that of a different Bond family, who came from England. So perhaps Bond is English, not Scottish. Bond went to Eton College, the same school as his creator Ian Fleming. This is a school where young people learn how to move in high society, like Bond does so well.After leaving school, Bond did not go to university. He joined the British Secret Service. He soon got promoted to the top. From then on he was 007, “licensed to kill”, and so began a career which would take him to all the corners of the earth. In the early days, Bond’s role was quite clear. He was working for the West. His main enemies were men from the KGB and other dangerous organizations. Since the end of the Cold War, the role of the Service has changed, and Bond’s job profile has changed with it. Now his main enemies are the big bosses of organized crime and international terrorism. Unlike the Cold War, organized crime is unlikely to come to an end. We can therefore be sure that James Bond, the best-known English fictional hero of the 20th century, has many more adventures ahead of him.1. The new Bond film made much money for its producer. ( )2.
