Success. More than four hours but I’ve finally reached my belly button,” said Weibo user GayleRabbit.Another user Lucy said, “Why does my belly button suddenly look and feel completely new?”,While the trend was popular with many female users on Weibo, a photo uploaded by a male blogger caught people’s eyes. “Is this pose really that difficult? I don't think so,” said Weibo user Sough Sa. His photo showing he was trying to touch his belly button drew 2,634 likes and was shared more than 8,452 times.“I always support failures. Now I don't feel so bad about not being able to touch my belly button.” said another user Jacket. “Do we need to have flexible(柔韧的) arms or a skinny waist to achieve it?” asked Weibo user Chantilly623.But some experts argued that China’s new belly button trend was actually distoring(歪曲) society's standards of beauty. “These poses and pictures can be fun but sometimes they also become an expression of competitiveness,” said Jole ne Tan, Programmes and Communications Senior Manager at Aware, a non-governmental organization in Singapore championing women's rights.However, experienced body trainers say the new trend is about flexibility of the arm and the size of the waist, rather than a good figure. A skinny person with fewer muscles(肌肉) has a better chance of achieving the pose.1．Between which two paragraphs can the following sentence be put in ?------“A new social trend(趋势) has started in China, with thousands of netizens facing the challenge and uploading photographs of themselves to show off their bodies”A．Para1 and Para2 B．Para3and Para4C．Para7 and Para8 D．Para9 and Para102．What can we learn from the passage?A．Boys are not interested in this trend.B．GayleRabbit reached her belly button on her first try.C．Sough Sa’s photo of reaching his belly button was popular online.D．Jacket felt sorry for not being able to touch his belly button.3．What is experienced body trainers’ opinion of the new trend meaning a good f igure?A．Supportive. B．Disbelieving.C．Doubtful. D．Worried.E17、Now cities are full of cars. Some families even have two or more cars. Parking is a great problem, and so is the traffic in around the cities. Something will have to be done to change it. What will the cars of tomorrow be like?Little cars may some day take the place of today's big cars. If everyone drives little cars in the future there will be less pollution in the air. There will also be more space for parking cars in cities, and the streets will be less crowded. Three little cars can fit in the space now needed for one car of the usual size.The little cars will cost much less to own and to drive. Driving will be safer, too. What is more, these little cars can go about 65 kilometers per (每) hour.Little cars of the future will be fine for getting around a city, but they will not be useful for long trips. If big cars are still used along with the small ones, two sets of roads will be needed in the future. Some roads will be used for the big, fast cars, and other roads will be needed for the slower small ones.1．What is the big problem for those people who have cars?A．Money. B．Parking. C．Time. D．Waiting.2．What does the underlined word “ take the place of ” mean in Chinese?A．花费B．地方C．超越D．取代3．People can money with using the little cars.A．spent B．cost C．save D．take4．Little cars are very fine for ______.A．everyday life B．journeys C．long trips D．sport5．What is this passage mainly about?A．The little cars are as useful as the big cars. B．What the cars of tomorrow will be like.C．There will be less pollution in the future. D．Cities are full of cars now.F18、When we think of food farming we usually think of green fields in the country, outside the city. Sam Chee works on a very different type of farm, in the center of the Canadian city of Toronto. “We grow fruit, vegetables and herbs,” says Sam. “But not many people know the farm is here. You can’t see it from the street. We’re on top of an office building, 50 meters above the ground.”Rooftop farming is becoming popular in cities like Toronto, New Y ork and London. The roofs of buildings are often just wasted space, but this space can be used for growing good fresh food, right in the middle of the city. Sam explains how it works. “We grow everything in big boxes—there are hundreds of them. We catch rainwater to water the plants when the weather is dry.”The rooftop farm where Sam works belongs to a restaurant called Green Garden, on the ground floor of the building. The farm produces about half the restaurant’s fruit and vegetables. Sam believes that the rooftop farm is what makes Green Garden special. “We help to keep food production local. We don’t need to transport this food from anywher e and that saves energy. It’s better for the environment.”The food from the rooftop is fresher too. “When the fruit and vegetables are ripe we can pick them and use them right away. They taste better when they’re really fresh,” says Sam. “I hope that ther e will be more rooftop farms in the city soon. It could be the farming of the future.”1．Green Garden’s rooftop farm is.A．the only one in the world B．in the middle of a small townC．one of many in cities around the world D．near the countryside of a city2．The fruit and vegetables Sam grows are .A．used in a restaurant in the same building B．sold to restaurants to cook dishes for peopleC．taken to a restaurant in another building D．given to people who work in the building3．Sam thinks the food from the rooftop is better than that bought from other places because .A．it is much cheaper and fresher B．it tastes better and is better for the environmentC．it uses space which was being wasted D．it can’t be bought in the local stores4．According to the passage, which of the following is RIGHT?A．The farm is on the top of a teaching building, 50 meters above the ground.B．The plants are watered by collected rainwater when necessary.C．Y ou can find more rooftop farms in the country than in the city.D．When t hey pick the fruit and vegetables, they won’t use them at once.5．What is the main purpose of the passage?A．To describe what rooftop farming is by giving an example.B．To describe why rooftop farming has become very popular in Canada.C．To tell the story of the man who first started rooftop farming.D．To encourage people to build as many rooftop farms as possible.Ⅴ.书面表达19、书面表达为配合我市开展“创建文明城市(build a civilized city)”活动，学校举办以“How to Behave Well”为主题的英语征文比赛。
