    _________(65)
    A:square
    B: division
    C:centers
    D:section

    答案:D
    解析:
    come into being为固定搭配,意思是“形成、产生”,例如:When did the Great Britain come into being?英国是何时形成的?原文是“美丽城市”的理念应运而生,因此选C。
    根据上下文判断,随着美丽城市理念的诞生,人们开始意识到城市需要被规划。come有“开始”的意思。所以此处选C最合适,其他各项均不合题意。fail失败, incline 和tend都有“倾向于”的意思。
    根据词语的搭配可以知道,原文应该指的是“城市开始通过城市区划法”,三个选项中只有选项A最合适,pass有“通过”的意思,和law“法律”搭配使用正确。
    空缺处需要填的是过去分词引导的定语从句,省略了which be。这里指的是被划分出来建公寓的地区不能盖工厂,zone更合适,意思是“将……划为特殊区域”。
    however表示一种转折的关系。本句意思为“工厂不能建在用于盖公寓的土地上。然而,公窝也不能盖在建造大宅的土地上”。所以选项D符合。
    根据前半部分即城市在快速地发展,可以判断出城市的变化也是很迅速的,选项D正确,意为“突然,很快”,与前面的rapidly呼应。
    traffic jam意思是“交通堵塞”,较之选项B,选项A更符合常理,即城市里的街道会造成交通堵塞。
    本句提到了老地区变得破败不堪,人们应该是搬出旧城区,搬进新的城市地区,所以选择C,后面接的介词to指“搬到……”。
    只有form最适合和后面的group搭配使用。form意为“组成”,例如:The two parties formed a coalition.两个政党组成了联合政府。本句意思是“市民们组成了试图解决城市面临的问题的团体”。
    三个选项中只有as适合,意思是“作为”。句子意思是“大多数的大城市都有了作为城市政府一部分的城市规划委员会”。
    逻辑题。on the board意思是“委员会里”。前面提到大多数城市都有了 city planning board即“城市规划委员会”,那么委员会里必然有城市规划师,所以A正确。
    degree意思是“学历”,后面常接介词in指在某专业方面的学历,原句中还有信号词college,所以选项degree最合适。level水平,qualification资质,height高度。
    best这里是副词,意思是“最好地,最高标准地”,比较carefully (小心地), suitably(合适地)以及cleverly(聪明地),选项B更为合适。原句意思是“这些城市规划师必须知道如何才能以最好的方式使用城市里的土地”。
    lay out为固定搭配,意思是“规划,设计”。例如:When the local governments lay out the car parks, they must estimate the numbers of cars in these districts.当地方政府规划停车场时,他们必须先估计市区里的汽车数量。原文是“他们规划城市的新地区”。
    这里的意思是“他们……决定如何来提升一个老城区”。section除了有 “部分”的意思外还指“(城市等的)地区,(街区等的)地段”。square意为“广场”,division意为“部分”,centers意为“中心”。

    【录音原文】
      For five years I lived in Singapore, a metropolis of almost three million people. Like London, Paris and New York, Singapore is a cosmopolitan city, with people from different parts of the world living and working together. I enjoyed the urban lifestyle I led there, and made the most of the super amenities, ranging from the excellent shops to some of the best restaurants in the world. In the evenings and at weekends there were always cultural events, with such diverse attractions as classical Western music, and exhibition of Malay art or a Chinese opera in the street, it was difficult to get bored. Perhaps most impressive, however, was the remarkable transport infrastructure, with excellent roads, a swift and efficient bus service and a state-of-the-art underground system which could whisk commuters from the suburbs straight into the heart of the city. This is particularly important, as the government banned private cars from entering the central business district during the morning and afternoon rush hours to reduce congestion on the roads and pollution from the exhausts.
      Of course, living in a city like this has its disadvantages as well. For a start, the cost of living can be very high—renting an apartment, for example, is very expensive. And as the city is expanding, there are a lot of building sites where new apartments are continually being built to deal with the population explosion which is a direct result of the government encouraging people to have more children.

    _________(64)
    A:put out
    B:lay out
    C:give out
    D:hard out

    答案:B
    解析:
    come into being为固定搭配,意思是“形成、产生”,例如:When did the Great Britain come into being?英国是何时形成的?原文是“美丽城市”的理念应运而生,因此选C。
    根据上下文判断,随着美丽城市理念的诞生,人们开始意识到城市需要被规划。come有“开始”的意思。所以此处选C最合适,其他各项均不合题意。fail失败, incline 和tend都有“倾向于”的意思。
    根据词语的搭配可以知道,原文应该指的是“城市开始通过城市区划法”,三个选项中只有选项A最合适,pass有“通过”的意思,和law“法律”搭配使用正确。
    空缺处需要填的是过去分词引导的定语从句,省略了which be。这里指的是被划分出来建公寓的地区不能盖工厂,zone更合适,意思是“将……划为特殊区域”。
    however表示一种转折的关系。本句意思为“工厂不能建在用于盖公寓的土地上。然而,公窝也不能盖在建造大宅的土地上”。所以选项D符合。
    根据前半部分即城市在快速地发展,可以判断出城市的变化也是很迅速的,选项D正确,意为“突然,很快”,与前面的rapidly呼应。
    traffic jam意思是“交通堵塞”,较之选项B,选项A更符合常理,即城市里的街道会造成交通堵塞。
    本句提到了老地区变得破败不堪,人们应该是搬出旧城区,搬进新的城市地区,所以选择C,后面接的介词to指“搬到……”。
    只有form最适合和后面的group搭配使用。form意为“组成”,例如:The two parties formed a coalition.两个政党组成了联合政府。本句意思是“市民们组成了试图解决城市面临的问题的团体”。
    三个选项中只有as适合,意思是“作为”。句子意思是“大多数的大城市都有了作为城市政府一部分的城市规划委员会”。
    逻辑题。on the board意思是“委员会里”。前面提到大多数城市都有了 city planning board即“城市规划委员会”,那么委员会里必然有城市规划师,所以A正确。
    degree意思是“学历”,后面常接介词in指在某专业方面的学历,原句中还有信号词college,所以选项degree最合适。level水平,qualification资质,height高度。
    best这里是副词,意思是“最好地,最高标准地”,比较carefully (小心地), suitably(合适地)以及cleverly(聪明地),选项B更为合适。原句意思是“这些城市规划师必须知道如何才能以最好的方式使用城市里的土地”。
    lay out为固定搭配,意思是“规划,设计”。例如:When the local governments lay out the car parks, they must estimate the numbers of cars in these districts.当地方政府规划停车场时,他们必须先估计市区里的汽车数量。原文是“他们规划城市的新地区”。
    这里的意思是“他们……决定如何来提升一个老城区”。section除了有 “部分”的意思外还指“(城市等的)地区,(街区等的)地段”。square意为“广场”,division意为“部分”,centers意为“中心”。

    正确答案: D
    解析:
    文章第一部分即第一段,点明主旨,提出将结束引起争议的手机禁令。第二部分包括第二、三、四、五段,指出这项禁令的实施所带来的利与弊。第三部分即第六段,指出教育部因此决定创建一个新的政策。由此可知正确答案为D(纽约很快会结束学校的手机禁令)。A、B项与主题不符,C项只是文章中的一个细节,只有D项才是文章的主要内容。
