14、amond是同位语成分，补充说明这个法国工程师叫什么名字。a French enginner arrived in England是句子主干，with后面整个的介词短语作伴随状语，修饰谓语动词arrived。介词短语for a twenty-one-mile tunnel作定语修饰plan。1.twenty-one-mile 复合形容词，只能作前置定语，mile以单数形式出现a two-year-old boy her six-year-old daughter 2.a plan for sth.的计划eg.Do you have any plans for this evening?We m

17、n 1860,a better plan was put forward by an Englishman,William Low.put forward 提出供考虑或讨论，将某事提前eg.We have put forward the date of our wedding by one week.我们把婚礼提前了一周forward 向前backward 向后eg.Forward!向前，前进！backward and forward.来回地，前后地go/move forward 向前走from this time forward 从此以后7.This would solve the prob

21、是fear invasion的,所以主句用的would have done,而且是被动语态，从句用had done。the British 英国人 9.It was officially opened on March 7,1994,finally connecting Britain to the European continent.connecting现在分词短语作伴随状语，表伴随状态，在开通的同时将英国与欧洲大陆连通1.c 2.c 3.c 前一句It would be possible to build a platform 意思为“建造一座平台是可能的”。该句的主语是A platfo

22、rm,需要选一个合适的动词做谓语，使它同前一句含义相同。a.could build 和d.would build 都是主动语态，但是本句的主语是物不是人，故都不应该用主动语态。b.would be built 和 c.could be built 都是被动语态，合乎语法，但是could be built(可能或能够被建成)比would be built(会被建成)意思更贴切，更接近前一句的含义，所以选c.4.c 该句的谓语动词suggested 后面只能跟动名词短语或that 从句，从句中用should加动词原形才合乎语法。所以只有c.building 是动名词，最符合语法，所以选c.a.b.

23、d.都不符合语法。5.b 6.b 因为主句的动词是would 加动词原形，所以if 引导的条件句应该是一般过去时，才能成为与现在事实相反的虚拟语气。a.would enter,c.will enter,d.enters 都不是一般过去时，只有b.entered 是一般过去时，因此只能选b.7.c a.interesting in;b.interested for 和 d.interesting for 这3个选择都不合乎习惯用法，不是正确的表达方式，只有c.interested in(对感兴趣)是固定短语，最合乎题目意思，所以应该选c.Special Difficulties8.c 只有c.v

24、entilation(通风)是前一句中的动词ventilated(通风)的名词形式，因此c.最符合题目意思，选c.而a.air,b.airing,c.circulation(循环，流通)都不是ventilate 的名词形式，所以多不对。air 有使通风的意思，跟ventilate 意思比较接近，但是ventilate 的名词形式是ventilation 而不是air,所以不用air.9.a 该句需要选一个同前一句中的put forward(提出)含义相同的动词，才能使两个句子意义相同。a.suggested(建议);b.intended(想要，打算);c.aimed at(瞄准，对着)和d.p

25、lanned(计划)4个词中只有a.同put forward 含义最接近，所以选a.10.b 该句需要选一个同前一句中的动词feared(害怕)意义相同的词或词组，才能同前面句子意义相同。a.in favour of(赞成，支持);b.afraid of(害怕);c.prevented(阻止);和d.ended(结果)中，只有b 同feared 意义相同，所以应该选b.11.b 该句需要选出一个同前一句中的动词connects(连接)含义相同的词或词组.a.mixed(混合);b.joined together(连接在一起);c.rejoined(再接合);bined(联合,结合)中,只有b.同connects 含义最接近,所以选b.12.b 该句需要选出一个同前一句中的completed(完成的)意义相同的词，以使两个句子意义相同。a.ended(结束);b.finished(完成，做完);c.prevented(阻止)和d.stopped(停止)中，只有b.同completed 含义相同，所以选b.
