15、t completes the sentence. 1 【正确答案】 C 【试题解析】 题干中的 “it seems that ”用的是一般现在时,表示在说话时“看来似乎好像是 ”; that从句中用的是一般过去时,表示 “她出席会议 ”是过去的事件。整句话表示现在做出的对过去某事的判断。四个选项中, B、 D用了一般过去时,时态不对; A没有表示 “过去 ”的语法手段,也不对; C项中的不定式用了完成体,表示过去时间,语义与题干中的句子完全一致,为答案。 【知识模块】 语法与词汇 2 【正确答案】 B 【试题解析】 主句中的动词 has anticipated为现在完成时的 “已完成 ”用法
16、,表示“已经预见到了 ”,强调现在的状态,因此定语从句中应该用将来时以表示 “(现在预见到 )某事将要发生 ”,因此 B为正确选项。 【知识模块】 语法与词汇 3 【正确答案】 C 【试题解析】 他辍学是真的,此处是陈述事实,而且动作已经发生,所以用一般过去时。 has to的过去时是 had to,没有过去完成时 had had to这种说法,故选C。 【知识模块】 语法与词汇 4 【正确答案】 B 【试题解析】 本句是在过去时间里 (昨天 )看将来动作 (詹姆斯要来 ),应该用过去将来时。因为 come/go/leave一类动词的进行时可以表将来, was coming表达的就是过去将来时
17、,因此 B是正确答案。 C项 had been coming是过去完成进行时,表达的意思是 “来 ”这个动作一直持续到昨天,与逻辑不合。 【知识模块】 语法与词汇 5 【正确答案】 D 【试题解析】 本句是一般性的陈述,没有理由用过去时或过去完成时,故排除 A和 C。选项 B中的 have to“不得不 ”表达的是被迫、不情愿的意思,与句子正面、肯定的意思相反。只有 D正 确地表达了说话者的观念持续到现在并将延续到将来的意思。 【知识模块】 语法与词汇 6 【正确答案】 A 【试题解析】 由句中的时间状语 for two days now可确定用现在完成时,而表示“失踪的 ”应该用 missi
18、ng,而不是 missed“被错过的 ”,因此选项 A正确。 【知识模块】 语法与词汇 7 【正确答案】 C 【试题解析】 主句用祈使句表达将来的概念, whenever引导的状语从句用一般用现在时表将来,先排除 B和 D。表示 “你方便 ”用 it is convenient to you,而不是you are convenient,故答案为 C。 【知识模块】 语法与词汇 8 【正确答案】 D 【试题解析】 从句意来看,怀特先生并不是工业交易会的长期雇员,所以不能用一般现在时;此外他正在休假期间,所以才有空做其他工作,所以包含过去含义的现在完成时和现在完成进行时都不合适;现在进行时与 “在
19、休假期间 ”相吻合,所以 D为正确选项。 【知识模块】 语法与词汇 9 【正确答案】 C 【试题解析】 is said后跟不定式,不能跟动词 -ing形式,排除 A和 B。从 句中的时间状语 in the past year可以看出动作已经发生并完成。 C项 to have made是不定式的完成式,表示动作发生在谓语动词之前,而 D项 to make表示动作没有发生,故 C项正确。 【知识模块】 语法与词汇 10 【正确答案】 C 【试题解析】 本句含有 if引导的条件句,从句中使用了 hadnt been,是对过去情况的假设,因此主句的结构应为 would have done,故答案为 C
20、。 【知识模块】 语法与词汇 11 【正确答案】 A 【试题解析】 本题条 件状语从句中的谓语动词用了过去式 explained,说明其内容与现在或将来的情况相反。所以主句的谓语动词应该用 “would+动词原形 ”,答案为 A。 【知识模块】 语法与词汇 12 【正确答案】 D 【试题解析】 题干中把糖放到酱汁里这个动作已经发生,因此本句是对过去情况的假设。 if条件状语从句应使用 had done,主句使用 would should could have done。选项 C和 D在语法上都对,不过 C用了肯定,表示 “如果你匆忙,你会把糖当成盐放到酱汁里 ”,意思上不合逻辑,故 D项正确
21、。 【知识模块】 语法与词汇 13 【正确答案】 B 【试题解析】 本句是省略了 if的虚拟条件句,原句的正常语序为: If it had not been for their help省略 if时,只提前助动词,否定词 not不用提前,即 Had it not been for 。故答案为 B。 【知识模块】 语法与词汇 14 【正确答案】 C 【试题解析】 ask作 “请求,要求 ”讲时,其后的宾语从句要用虚拟语气,从句谓语动词使用 “(should+)动词原形 ”。类似用法的动词还有 demand, suggest,order, require, desire, surprise等等。
22、【知识模块】 语法与词汇 15 【正确答案】 A 【试题解析】 在 “It is was+形容词 +that从句 ”中, that引导的主语从句谓语动词常用 should+动词原形。用于该句型的形容词有 necessary, good, important,right, wrong, better, natural, proper, funny, strange, surprising等。 【知识模块】 语法与词汇 16 【正确答案】 C 【试题解析】 It is essential that句型中, that引导的从句用虚拟语气,谓语动词用 “should+动词原形 ”, should可以省
23、略。故 C为正确选项。类似的形容词还有: important, necessary, imperative, advisable, desirable等。 【知识模块】 语法与词汇 17 【正确答案】 B 【试题解析】 If only从语义和用法上都相当于 I wish,后面的谓语动词用一般过去时表示目前的愿望,用过去完成时表示 过去的愿望,用 would could do表示对将来期望。选项中首先可排除 C和 D。而 A项 would侧重指人的意愿, B项 could是指人的能力。句子的意思主要是指弹钢琴的能力,所以应该选择 B。 【知识模块】 语法与词汇 18 【正确答案】 C 【试题解析
24、】 本句的主句使用了祈使句,而非虚拟,因此从句应理解成对真实情形的一种假设。 A项使用一般过去时。是对现在或将来情况的虚拟,而 if真实条件句应使用一般现在时表示将来,所以 A不正确,应该使用 if you have; B和 C都省略了 if, B项 have had是对过去情况的虚拟,不正确; C项中的 should用在假设句中,加强语气, should have是对将来情况的假设,故 C为正确答案;D项 in case“万一,以防 ”引导的从句使用一般现在时或 should+动词原形,不能用had。 【知识模块】 语法与词汇 19 【正确答案】 A 【试题解析】 It is recomme
25、nded that表明 that从句需要使用虚拟语气,其形式为 “should+动词原形 ”。其中 should可以省略,故答案为 A。 【知识模块】 语法与词汇 20 【正确答案】 B 【试题解析】 it is (about)time(that)是一个虚拟语气句型,所跟从句的谓语动词用一般过去式,故 B项 were为答案。 【知识模块】 语法与词汇 21 【正确答案】 C 【试题解析】 was were to have done sth表示 “本来要做成 的 ”,表示与过去事实相反,从句谓语动词应使用 had done,所以应选 C。 【知识模块】 语法与词汇 22 【正确答案】 A 【试题
26、解析】 would rather“宁愿 ”后 接从句时,从句动词用一般过去式表虚拟,故答案为 A。注意区分 would rather其他两个惯用句式: would rather do sth “宁愿做某事 ”: would rather do than do“ 宁愿做 而不愿做 ” 。 【知识模块】 语法与词汇 23 【正确答案】 A 【试题解析】 It is (high) time (that)后面的从句谓语动词要用过去式或 “should+动词原形 ”,且 should不可省略,故 A项 stopped为答案。 B项 had to stop表示 “一定 要停止 ”, C项是将来时, D项动词原形,都不符合条件。 【知识模块】 语法与词汇 24 【正确答案】 A 【试题解析】 if only常常用来表达强烈的愿望或遗憾,由于 “接受不同的治疗 ”与过去事实相反,所以用过去完成时,故 A项 had received正确。 【知识模块】 语法与词汇 25 【正确答案】 B 【试题解析】 若陈述部分含有 seldom, hardly, never, rarely, few, nothing,nowhere等否定词或半否定词,其反意疑问句部分要用肯定式。同时句 中时态是一般现在时,故选 B。 【知识模块】 语法与词汇
