12. 定冠词the的习惯用法
①某家人或某夫妇一般用the 复数。如：the Smiths
②表示整个民族或族人一般加the。如 the Chinese/English
③少数山脉群岛也不用the。如Mount Tai。如名词中有of短语则一般有the.如：the Mountain of seven sighs.
④中国的湖泊一般加 the。如：the West Lake.

刊物、公告与标题，普通名词并列紧相邻；
唯一职位，学科与语种，洲、国、省、市、县街路名。
13. 动词形式的变化
动词根本是原形，变化形式有四种：
原形词尾加“s”，现在第三单人称；
过去原形加“ed”，过去分词也相同；
原形加上“ing”，现在分词或动名。
原形词尾加“s”，如同名词复数式。
若加“ed／ing”，以下情况要注意：
词尾有e只加d，ing去无声e；
词尾ie变成y，然后再加ing；
辅音之后y结尾，y要变i加ed；
现在分词不变y，直接加上ing ；
词尾重读闭音节，加缀辅音都双写，
r做结尾也一样，重读音节r双写；
结尾字母是“t”，不是重读也双写。
过去分词过去式，不按规则也有些。
14. 基数词变序数词
第一、二、三要全变，其余“th”加后边，你需格外记明白：
八减t，九减e，字母f代ve，ty变tie
①one—first，two—second，three—third
②four—fourth,seven—seventh,hundred—hundredth
③eight—eighth，nine—ninth
④five—fifth，twelve—twelfth
⑤twenty—twentieth，sixty——sixtieth
15. 直接引语间接引语的记忆口诀
人称变更怎么办？“一主①、二宾②、三不变”③
若是自引自的话， 听者不变称不变。
注：
①“一主”指在直接引语中的第一人称变为间接引语时，要和主句中的主语在人称上保持一致。
如：He sad,“I am forty，”→He said that he was forty．
②“二宾”指直接引语中的第二人称变为间接引语时，要和主句中的间接宾语保持人称一致。
如：He said，“Are you coming tomorrow？”→He asked me if I wascoming the next day．
③“三不变”指直接引语中的第三人称变为间接引语时，人称不变。
如：He said，“Is she an English teacher？”→He asked if she was an English teacher．
另外注意直接引语为复数，引述者主语为单数，间接引语主语相应变复数。
如：He said，“Are you interested in English？”→He asked me/us if Iwas/we were interested in English
16. 被动语态记记口诀
一般现、过用be done，be有人称、时、数变。
完成时态have done，被动将been加中间。
一般将来shall (will) do，被动变do为be done。
将来进行无被动，shall (will) be doing,
现在完成进行同，have (has) been doing。
现、过进行be doing, 被动be加being done。
复杂的东西这么学，
一下子轻松了，有木有？

【答案与分析】
1. D。所空部分为省略结构，完整说法是：(as...as he)spent studying. 此处用did代替spent。
2. D。根据句意应该是“我说不出我有多么想他”。
3. B。动物的演变为主动，无被动之意，而且develop作为不及物动词是“发展”、“演变”的意思，作为及物动词是“开发”的意思。
4. B。我们很容易受“prefer...to..”的影响而误选A。根据上下文，“我”想要的是“加牛奶的咖啡”。
5. D。名词所有格后面要接动名词形式。late是形容词，故不能选C。
6. D。这是考查宾语从句。宾语从句要用陈述句语序。用why引导宾语从句时后面不能接介词for。
7. C。unless是“除非”的意思，相当于 if not。当主句的谓语是一般将来时的时候，由unless引导的状语从句要用一般现在时。
8. B。这是考查分数的表达法。分子用基数词，分母用序数词。当分子超过“一”时，分母的序数词要用复数。谓语应和分数后的部分保持一致。
9. A。这是学生容易弄错的。reach=arrive at (in)=get to。
10. D。这是考查动词不定式作定语的用法。动词不定式作定语时，与前面的名词存在动宾关系，故要用及物动词，如不是及物动词要补上适当的介词。
11. A。try out是“尝试”的意思，try on才是“试穿”的意思，其中的on是副词，them应放在中间。
12. C。有些同学认为such用来修饰名词work，故选B。但是so many 或so much 是固定搭配。
13. D。“让别人做”要用“have sth. done”结构。
14. B。steal和rob的用法不同。它们的固定搭配是：steal sth. from sb.; rob sb. of sth.。
15. C。这是学生很容易错的题目。要分清这几个词的变化形式：lie (说谎)—lied, lied; lie (平躺)—lay, lain; lay (生蛋)—laid, laid。
16. D。thanks for是“感谢（事情）”的意思，thanks to是“幸亏”的意思。because 后面接从句，不可选。
17. C。这是考查if和whether的用法区别。当前面有介词时要用whether。该句中whether和动词不定式一起做about的宾语。
18. B。这是一种虚拟语气。当 as if 用来表示现在或将来不可能做到的动作时要用一般过去时。又如：He treats me as if I were a child. （他把我当小孩看待。）
19. A。要注意这些词形很相像，但意思不同。sometime（未来）某时，some time一些时间，sometimes有时，some times几次。根据句义“下个月某个时间他将来和我们呆一段时间”很容易作出选择。
20. B。be worth doing结构中的动词要用及物动词，如动词本身不是及物动词，要加上适当的介词。
21. D。当must表示“猜测”时，反意疑问句部分与must后的词保持一致。又如：He must have come back, hasn’t he? （他一定会来，是吗？）
22. C。当比较的两个事物不在同一个范围里时，不用other来排除，只用any。
23. C。alone 在句中只能作表语或状语，意思是“单独的（地）”；lonely在句中既可以作表语，也可以作定语，意思是“孤独的”。
24. C。sound（听起来）后面可以直接接形容词作表语，如果后面是名词时要加like。
25. C。buy和get是非延续性动词，不能用在表示延续的现在完成式中。
26. C。to one’s (great) surprise是一个固定短语，意思是“使某人惊讶的是”。
27. C。“the 比较级，the 比较级”是一个固定句型，表示“越……，越……”。
28. C。with one’s help 是固定短语，意为“在……的帮助下”。不能受汉语的影响而选A。
29. B。used to do (be) 表示“过去常常做（是）”，而be used to sth. / doing sth.表示“习惯于……”。
30. B。do you think 在句中是插入语，如果将此插入语拿掉，答案就很明显了: What made him change his mind?
31. C。practise doing sth.是固定搭配。
32. A。我们可用“such a (an) 形容词 单数可数名词”，也可用“so 形容词 a(an) 单数可数名词”，因此 so good a book =such a good book。
33. B。offer sth. to sb.是固定搭配，意为“向……提供……”。
34. C。feed on是固定短语，意为“以……为食”。
35. B。It’s a pleasure, Not at all和You’re welcome都是用来回答别人的感谢，意为“不用谢。” With pleasure用来回答别人的请求，意为“愿意效劳”。
36. C。动词不定式to do作way的定语，如果用 of 后面要接doing 。
37. B。这是“get sb. to do sth.”结构。要注意句中的her是宾格，而不是物主代词，故不能选D（studies 学业)。
38. B。can’t wait to do sth.是固定表达法，意为“迫不及待地做”，而wait for后面只能接名词或代词，不能接动词。
39. B。这是考查对hang一词的理解。hang有两种意思，一为“悬挂”，其过去式和过去分词都是不规则的（hung, hung)，一为“吊死、绞死 ”，其过去式和过去分词是规则的（hanged, hanged）。
40. C。so that表示目的或结果，意为“以便于、结果”。
41. D。find (found, found)是“发现”，found (founded, founded)是“建立”。一个组织或国家的建立应用被动结构。
42. D。“多少乘以多少”要用multiplied by 来表示。
43. C。have someone do sth.是一种固定结构，意为“请别人做”。
44. D。“赢得比赛”要用win, “打败某人或某个队”要用beat。
45. C。as a result of 是“由于……的缘故”的意思，as a result 是“结果”的意思。because 后面不能接名词，because of 后面才可以接名词。
46. B。surprising 是“令人惊讶”的意思，surprised是“感到惊讶”的意思。“面露惊讶之色”显然是“感到惊讶”。
47. B。主句用的是过去完成时，说明主句动作发生在“he got up”之前。by表示“到……为止”，当它引导的时间状语是一般过去时的时候，主句应该用过去完成时。
48. B。worth一般用于be worth sth./doing sth.句型中。rewarding 是个普通形容词，意为“值得的”，deserve 是动词，意为“应得、值得”，后接名词或动词不定式。
49. B。这里用动词ing结构作表语。
50. B。这是定语从句，先行词如果是“物”时要用 that 或 which 来引导，what只能引导一个宾语从句或主语从句。
51. C。afraid的意思是“恐怕”，frightened是“受惊吓”的意思。
52. D。当keep sb./sth. (from)dong 变为被动句时，from不能省。
53. B。pride是名词，意为“引为骄傲的人”，proud是形容词，意为“感到骄傲的”。be proud of 意思是“对……感到骄傲”。
54. C。“……被穿坏了”要用be worn out 来表示。
55. A。“Don’t rush”还可以表示“别急”的意思。
56. A。long before 是“很久之前”的意思，before long是“不久之后”的意思。
57. D。too much 是too 修饰much ，意为“太多”，much too是much 修饰too，意为“非常、太”。
58. C。has是动词，应用名词作宾语。interesting和interested是形容词。
59. B。make a contribution to 中的to 是介词，后面要接ing形式。change the environment不符逻辑。
60. B。borrow意为“向……借”，lend意为“将……借给”。
61. B。carry on后可以直接带名词或代词作宾语，而go on要加介词with后才能带名词或代词作宾语。

63. D。put off意为“推迟”，put on意为“穿（戴）上”，put away意为“收好”，put right意为“修理”。
64. C。wonder if表示“对……感到怀疑”。wonder 后面不能接that从句。
65. D。be able to 是固定短语。在这里是if I am able to help you的省略，一定要保留to。
66. C。这里是句型 think it adj. to do sth.，意为“认为做……怎么样”。其中it是形式宾语。
67. C。由no matter 引导坏状语从句，当主句用一般将来时或情态动词的时候，从句要用一般现在时。happen为不及物动词，不能有被动语态。
68. C。说“什么东西（人）有毛病”的时候，我们用there is something wrong 来表示。这里的wrong可以用matter来替换，但一定要加定冠词the。
69. C。被动语态的谓语要用及物动词，如果不是及物动词，要补上适当的介词。该句的主动语态是“We must speak to older people politely.”，改成被动句时to不能省。
70. B。根据分析该句的意思应该是“即使你不知道如何去做，你也要尝试一下”。though“虽然”，as though“好像”，even though“即使”。
71. B。当When will he be back 中加入插入语do you think时，do you think 后的语序应该用陈述句语序。back 是副词，不能放在will的后面。

73. C。在not...until 结构中，谓语要用非延续性动词，如果是延续性动词，则不用否定句。
74. B。注意so he is 和so is he的区别。前者表示“他的确是这样”（表示赞同），两句的主语是指同一个人；后者表示“他也如此”，两句的主语不是同一个人。

76. C。如果用动词 to go 或 to travel 做定语，后面都要加to，而to visit后是不能加to的。

78. B。如果选A，则谓语要用一般过时，如果选D，则谓语要用过去完成时，如果选C，则表示已经住了1996年，显然不符逻辑。
79. D。yo-yo是一种玩具，玩它要说play with the yo-yo。It’s great fun后要接动词的-ing形式。
80. A。“what 动词不定式”作know的宾语，在意思上what是do的宾语，因此不能再加it。

82. A。我们可以将had better作为情态动词。
83. D。leave sb./sth. doing 表示“将... ...留下做... ...”。

85. C。“我”所认识的女孩不止一个，因此要用最高级。
86. A。in the 1960s 表示“20世纪60年代”，这是一种固定说法。

90. C。问人口 (population) 的“多少”要用what不用how many (much)。
91. B。book为预订“票”，order则为预订“货物”或“点菜”。票要预订显然用被动语态。

93. A。“往……抛垃圾”可以用“litter 地方”来表示。
94. C。“进了几个球”、“得了几分”要说score...goals。这里的goal表示“得分”、“进球”的意思。
95. D。give in屈服，give up放弃，give back归还，give away捐献。
96. C。enter是及物动词，意为“进入到……里面”，后面不能再接介词。
97. B。这里用副词really来修饰形容词English。
98. C。当宾语从句表示客观规律时动词要用一般现在时。
99. C。动词不定式 “to complain too often” 在句中作主语，用it就重复了。如果将动词不定式置于后则要用it来代替：It isn’t a good thing to complain too often。
100. C。当hundred, thousand, million和billion前面用具体数字时来限定时，不用复数形式。hundreds of / thousands of / millions of表示“数百”、“数千”、“数百万”，它们可以用many, several等来修饰。
