Ⅰ.单句语法填空(建议用时：7分钟)
1．As far as I know, such things are not allowed to_be_carried(carry) with you when you take a plane.
解析 此处是be allowed to do sth结构，逻辑主语such things和carry之间是动宾关系，故用动词不定式的被动语态。
2．George returned home after the war, only to_be_told(tell) that his wife had left him. 解析 根据题干中的only以及语境可知，此处应用不定式作结果状语，空处的逻辑主语George与tell为动宾关系，故用动词不定式的被动语态。
3．If they win the final tonight, the team will tour around the whole city to_be_cheered(cheer) by their enthusiastic supporters.
解析 句意：如果他们今晚赢了决赛，队员们将环游全城，去接受热情的支持者的喝彩。空处的逻辑主语the team与cheer为动宾关系，故用动词不定式的被动式作目的状语。
4．We're having a meeting in half an hour. The decision to_be_made(make) at the meeting will influence the future of our company.
解析 句意：我们半个小时以后开会。在会上作出的决定将会影响我们公司的未来。根据题干中in half an hour和will可知，是即将作出的决定，故用不定式的被动式作定语。
5．Students hold different opinions towards the news of the score of English to_be_decreased(decrease) for the College Entrance Examination. 解析 句意：学生对高考英语分值要下降的消息持有不同的看法。the score与decrease为动宾关系，故用to be decreased表示“将要被降低”。
6．The children were not to_blame(blame) for the accident. After all, they were still so young. 解析 句意：孩子们不应该因为这起事故而受到责备，毕竟他们还这么小。be to blame应受责备，常用主动形式表示被动意义。
7．The old man sat in front of the television every evening, happy to_watch(watch) anything that happened to be on.
解析 be happy to do sth快乐地做某事，watch的逻辑主语是the man，与谓语watch构成主谓关系；如果填watching，则应用happily修饰，故填to watch。
8．Our teacher always says there is no time to_lose/to_be_lost(lose)．
解析 句意：我们老师经常说没有可以失去的时间了。可将to lose看成for us to lose；用to be lost，逻辑主语time与lose构成动宾关系，表示是谁失去时间不明确。
9．The No.1 underground, hopefully to_be_opened(open) in the near future, will greatly improve the traffic conditions.
解析 句子的谓语是will improve，此处应用非谓语动词，主语The No.1 underground与open为动宾关系，根据时间状语in the near future可知，此处指将来的动作，故用不定式的被动式。
10．Though the question sounds easy, it is very difficult to_answer(answer)． 解析 此处是“it is＋adj.＋to do sth”结构，不定式用主动形式表示被动意义。 Ⅱ.阅读理解(建议用时：7分钟)
The Thames Barrier is a system that prevents London from being flooded by North Sea storms. It lies in the eastern part of London, about 15km from the Houses of Parliament. The Thames Barrier was built in the 1970s and has been in operation since 1982. It cost over ￡500 million and is operated by the Environment Agency.
In normal weather, tides cause the Thames River to rise and fall by about 5 meters twice a day. Heavy storms in the North Sea, however, combined with rising tides can push too much water up the Thames and flood central parts of the city. When this happens, the gates of the London Barrier are raised to keep water away from the city.
In the course of history, London has witnessed many cases of extreme flooding. The worst event took place in 1953, when 300 people died during a heavy storm that spread across the North Sea and flooded the city. After this disaster, city planners decided that something had to be done to protect the city.
Today, 10 rotating steel gates span the 520-metre wide Thames River. Under normal conditions, the five-storey-high gates are down and ships can pass through. When danger approaches, the 3,000-ton gates can be raised within minutes to keep extra water out of the city area. Since the opening of the barrier in 1982, the gates have been closed over 170 times. Recently, however, the gates have been closed very often due to rising sea levels.
The Thames Barrier protects over a million people who live and work in Central London. It also protects historic buildings, infrastructure(基础设施) and the London underground.
The barrier was originally designed to protect London up to the year 2030. Climate experts
say that sea levels are rising slower than predicted so that the barrier will be operational through to 2070. Still, changes must be made to the barrier so that it can cope with extreme weather situations in the future.
