6、正在被攻击 be under considerationbe being considered 正在被考虑 be under constructionbe being constructed 正在被建设 be under discussionbe being discussed 正在被讨论 be under protectionbe being protected 正在被保护 be under repairbe being repaired 正在被修理 单句语法填空 例 1.

7、come close to a dog again. A. Bite B. Having been bitten C. Being bitten D. Biting 解析：句意：由于被狗咬过，这个小女孩突害怕再次靠近狗。根据句意“被狗咬”可知此处为被动， 联系语境“再次”可知“咬过了” 。故要用现在完成分词的完成被动形式。由此可知本题答案。 答案：B 例 2.（2014 天津高考） We wont start the work until all the preparations _. A. are being made B. will be made C. have been made D.

8、 had been made 解析：通常说来。在时间状语从句中使用一般现在时代替将来时，前面的主句中使用将来时。在高 中英语中也使用现在完成时代替将来时，表示到将来某个时间已经完成的事情。句义：直到所有的 准备工作都做好以后， 我们才开始工作。 A 选项为现在进行时的被动， B 选项为一般将来时的被动， C 选项为现在完成的被动，D 选项为过去完成时的被动。由此可知本题答案。 答案：C 例 3. (2015 西城区高三上期末) This ferryboat _ to transport passengers between the harbor and the island for years

9、. A. is used B. was being used C. is being used D. has been used 解析：本句的主语“ferryboat”与谓语动词“use”之间为被动关系，所以要用被动语态。又由“for years” 可知要用现在完成时的被动。由此可知本题答案。 答案：D 例 4. (2014 福建三明月考)Its true that whoever _positive for H7N9 will receive free medical treatment from our government without delay. A. is tested B. i

10、s being tested C. has tested D. tests 解析：由语境可知本句所表达的句意为：无论谁被检测出确实携带 H7N9 病毒都会毫不耽误地接受 政府的免费医治是真实的。谓语 test 与句了主语 whoever 为被动关系，联系语境可知用一般现在时 的被动语态。由此可知本题答案。 答案：A 例 5.(2015 四川高考)More expressways _in Sichuan soon to promote the local economy. A. are being built B. will be built C. have been built D. had

11、been built 解析：句意为：四川将建设更多的高速公路以促进当地的经济。由此可知本题答案。根据时间状语 soon 可知，考查了将来时，又因句子主语 expressways 与动词 build 之间为动宾关系所以要用一般将 来时的被动。故可知本题答案。 答案：B 基础演练基础演练 一用所给词的适当形式填空 1. Can I use your telephone?
