必修五 Unit1-2 阶段语法聚焦  1.She will tell us why she feels so strongly that each of us has a role ________in making the earth a better place to live. A.to have played B.to play C.to be played D.to be playing 【解析】 当动词不定式与所修饰的名词之间为动宾关系,同时与句子主语为主谓关系时,动词不定式用其主动形式表示被动意思且由题干从句中的时态(has a role)来看,为一般现在时,故此处表示“起作用”,并非是已完成的动作或正在起作用,故B项正确。 【答案】 B 2.The news reporters hurried to the airport,only________the film stars had left. A.to tell B.to be told C.telling D.told 【解析】 句意:记者匆忙赶到机场,结果却被告知影星们已离开。only/never/...+to do常用此结构作结果状语表示“结果却是……”,指出人意料的结果。tell是及物动词,之后常常带双宾语结构,而根据句意,tell应采用被动形式。 【答案】 B 3.With a lot of difficult problems________,the newly-elected president is having a hard time. A.settled B.settling C.to settle D.being settled 【解析】 句意:新上任的总统正面临一个困难时期,因为有很多难题有待解决。本题考查“with+n.+动词不定式”这个独立主格结构作伴随状语。with sth.to do在句中作原因状语,是固定搭配。根据句意可知,问题应该是有待解决,故选C。 【答案】 C 4.It's neccessary to be prepared for a job interview.________the answers ready will be of great help. A.To have had B.Having had C.Had D.To have 【解析】 句意:为工作面试做好准备很有必要。把答案准备好会有极大的帮助。根据后面句子中的“will be...”排除C项;A、B两项表示过去已经发生的动作;D项表示一种动作的全过程(to do)。根据句意可知并非指过去的动作,而是强调动作的过程。 【答案】 D 5.The mother felt herself ________cold and her hands trembled as she read the letter from the battlefield. A.grow B.grown C.to grow D.to have grown 【解析】 句意:当这位母亲读着这封从战场上寄来的信时,感到浑身发冷,手也颤抖不停。grow与逻辑主语herself之间是主动关系,feel可用于“feel...do/doing sth.”结构,由此可判断A项正确。 【答案】 A 6.________late for class,we got up very early. A.In order not to be B.So as not to be C.In order to be not D.So as to be not 【解析】 句意:为了不迟到,我们起得很早。in order to 可放在句首,否定形式为in order not to;而so as to不可放在句首,故选A。 【答案】 A 7.He let me repeat his instruction________sure that I understood what was________after he went away. A.to make;to be done B.making;doing C.to make;to do D.making;to do 【解析】 句意:为了确保他离开后我能明白干什么,他让我重复他的命令。非谓语动词作目的状语要用不定式,what was to be done是不定式表将来,这里是被动含义,用不定式的被动形式。 【答案】 A 8.When asked why he went there,he said he was sent there ________for a space flight. A.training B.being trained C.to have trained D.to be trained 【解析】 句意:当问他为什么去那儿时,他说他被派到那里是为接受太空飞行培训。根据he与train的关系可确定用不定式的被动式,表示“受训”。动词+-ing形式的被动式的一般式表示这个被动的动作正在进行。A、C两项分别是动词+-ing形式和不定式的完成式,都不表示被动,所以是错误的,故选D。 【答案】 D 9.The purpose of new technologies is to make life easier,________it more difficult. A.not make B.not to make C.not making D.do not make 【解析】 句意:新科技的目的是让生活更安逸而不是更艰苦。不定式作表语时往往带有较强的目的性。不定式的否定形式是在to之前直接加not。 【答案】 B 10.—The light in the office is still on. —Oh, I forgot________. A.turning it off B.to turn off it C.to turn it off D.having turned it off 【解析】 句意:——办公室的灯还亮着呢。——哦,我忘记关灯了。forget to do sth.“忘记做某事”(某事还没有做);forget doing sth.“忘记做了某事”(事情已经做了)。短语turn off是由动词加副词构成的,其宾语是代词时要放于turn与off之间。 【答案】 C 11.He's considered________a weak leader and he's considering ________his job. A.being;to quit B.to be;to quit C.to be;quitting D.being;quitting 【解析】 句意:他被认为是一个不称职的领导,所以他正在考虑辞职。consider意为“认为”时后跟不定式作宾补,即consider sb.to be,此处是被动形式sb.is considered to be;而consider作“考虑”讲时,后跟动名词作宾语,即consider doing。 【答案】 C 12.Do let your mother know all the truth.She appears________everything. A.to tell B.to be told C.to be telling D.to have been told 【解析】 句意:得让你妈妈知道所有的真相,她好像已经被告知了全部事情。被告知一切事情发生在appears之前,所以要用不定式的完成式,而此处又是被动语态,所以要用appear to have been done。 【答案】 D 13.Helen had to shout ________above the sound of the music. A.making herself hear B.to make herself hear C.making herself heard D.to make herself heard 【解析】 句意:海伦不得不大声说话,以使自己在嘈杂的音乐声中被听到。make+宾语+done表示宾语和补语之间是被动关系,故选D。 【答案】 D 14.David threatened________his neighbour to the police if the damages were not paid. A.to be reported B.reporting C.to report D.having reported 【解析】 句意:大卫威胁说,如果损坏没有得到赔偿的话,他就把邻居告到警察那里去。threaten to do sth.“威胁要做某事”。 【答案】 C 15.________,the basketball match will be put off till Thursday. A.Weather considers B.Weather considering C.Weather is considering D.Weather considered 【解析】 句意:考虑了一下天气,篮球比赛将推迟到周四举行。consider的逻辑主语不是basketball,consider和weather的关系是动宾关系,因此要用过去分词的独立主格结构。 【答案】 D 16.John received an invitation to dinner,and with his work________,he gladly accepted it. A.finished B.finishing C.having finished D.was finished 【解析】 句意:约翰收到一个晚餐邀请,因为工作完成了,所以他很高兴地接受了邀请。工作是被动的,因此应该用过去分词作宾补构成独立主格结构。with不是连词,因此后面不能出现谓语动词形式,因此不选D项。 【答案】 A
