But China has done a good job of dealing with it and it has found its own way to fight poverty.Instead of just giving money to poor people,it has tried to educate people and give them the tools they need to lift themselves out of poverty.Ordinary(普通的)people play a big role in the fight.Here are two of them. Miss Zhang, 66, has been helping girls pursue(追求)education since she traveled toYunnan at the age of 17. As a teacher, Zhang was heart-broken when she saw her students quit school(辍学)after finishing senior high school. They couldn't go to college because their families couldn't afford it. So in 2008, Zhang started a free school for poor girls.Since then, Zhang has been busy asking for donations(捐款)to provide money for the school. She has convinced parents to send their daughters back to school.The school has sent more than 1,800students to universities and colleges. Mr.Mao, 64, works as the Party secretary of his village. But there was only one pathway out of the village for many years. So he led more than 100 villagers to build a road with their hands. _____________. Mao then encouraged the villagers to grow oranges. Young people have returned to the village to sell oranges online. By the end of 2019, 269 villagers had been lifted out of poverty. The per capita income(人均收入) reached 12,670 yuan,40 times more than in the 1990s. Over the last eight years, 98.99 million rural been lifted out people have been lifted out of poverty. The 832 counties and 128,000 villages which these people live in are no longer in poverty. China has been responsible(负责的)for reducing 70 percent of poverty world wide since the late 1970s.

C There are a number of fun holidays in the world, such as World Sleep Day, Bird Loving Day, and Clean off Your Desk Day. The seventeenth day in the first month of the year is Kid Inventors’ Day (KID), a day to encourage all the children to think actively and try inventing something new. The holiday commemorates the birthday of Benjamin Franklin, and celebrates(赞扬) kid inventors around the world. It also encourages children to be creative when solving problems. Benjamin Franklin was one of this country's greatest inventors. When he was still a playful child, he invented the precursor(前身) to the swimming flippers(脚蹼)at the age of eleven. It was a year after he stopped going to school. You may think the invention helped our feet, but to your surprise, in fact, it helped the hand instead of the foot. Then how to celebrate the holiday? Here is some advice. If you have children or there are children around you, you can follow the advice. For example, you are a parent or a teacher. ★Give the kids problem-solving toys and games to help them develop thinking skills. ★Encourage the kids to search for ideas to solve problems in anew way. If a child has an idea for a game or something else, help him make his dream come true. ★There are quite a few stories about children inventing things. Collect such stories like“Little Inventors”and“Smart Young Edison”. You can spend some time talking to the kids about kid inventors, and encourage them to learn from them.

I'm your host, Jordon. When traveling in another country, you could easily get lost. Without a map or GPS, how will you find your way? 51 So before you travel abroad, take a moment to review how to ask for directions in English. Remember: don't be shy, just try! Asking for directions. In fact, there are lots of ways to ask for directions like “Hi. Can you tell me how to get to Times Square?” or “Excuse me. Where is the closest supermarket?” or “Hello. I'm looking for the nearest subway station ...” Giving directions. Here are three tips about words and phrases often used to give directions. ◆Basic patterns First, use basic English to offer directions. Short phrases are the best. Speak slowly and use very careful pronunciation. Spell out a word if necessary. You can use this sentence pattern to start:The easiest or best way is to... 52 Go head, turn left...For example:The easiest way is to go down Main Street. Stay on Route 66 and head north for about ten minutes. ◆Smart transitions (过渡) and prepositions Next, listen for “smart transitions”. The person you ask directions from might use a transition word or phrase to separate each leg of the route(路线). This makes his or her instructions easier to understand. For example, you might hear them say: after that, then, next, or when you get to...and finally... 53 For example: “It takes awhile” or “It's about a three-minute walk”. You might also hear prepositions. They tell you how far away the place is. For example: “It's opposite the post office” or “It's around the corner from the 7-11”. ◆Landmarks(地标) That leads us to the last point—landmarks. Landmarks are some special structures. 54 When giving directions, people often use some landmarks to help guide travelers. For example: It's across from the post office. You will pass a KFC restaurant on your right. Pay attention to your manners(礼仪). Finally, when asking a stranger for directions, remember your manners. Always say “excuse me” “please” and “thank you”. Also, don't forget to smile and speak in a clear voice. 55 That's all for today's episode(集)of Survival English. See you next time! A.For example,a tower or a restaurant can help you know about where you are. B.Sometimes people use numbers and distances(距离)that are guesses C.And then connect with the following phrases. D.That way, people will be more willing(愿意的)to help you find your way. E.The best way is to ask a local (当地人)for directions. F.It's impolite to make indirect requests. 第三部分：非选择题部分（共计50分） 第一节 语法填空（本大题满15分，每空1.5分） 阅读下面的短文，在短文空白处填入一个恰当的单词或括号内单词的正确形式。 The 24-kilometer-long Shenzhen-Zhongshan Bridge is another great bridge in China after the Hong Kong-Zhuhai-Macao Bridge.The construction(建筑) of it 56.
