参考答案:
知识点1
前面;中间;主语
1-1 As句意:众所周知,大多数的排名都是基于其他人对产品或相关服务的评价。考查非限制性定语从句。设空处引导非限制性定语从句,指代整个主句,在从句中作宾语,意为“正如”,应用As。
1-2 as句意:尽管它尝起来没什么特别,它仍然值得试,就像疙疙瘩瘩的猫头苹果一样,与其说它是件其他的任何东西,不如说是一件罕见而有趣的东西。考查非限制性定语从句。设空处引导非限制性定语从句,意为“正如,就像”。故填as。
1-3 as句意:众所周知,过多的脂肪对健康有害。考查定语从句。as is well known众所周知,as为关系代词,引导非限制性定语从句,且有“正如”之意。
知识点2
1. do 2. doing 3.done 4.被动语态
2-1 moving句意:经过长时间的仔细搜查,格雷格在远处的一片田野上看见那条狗在谨慎地移开。考查非谓语动词。saw后的宾语是 the dog,能够发出move的动作,而且根据句意可知该动作正在进行,因此用现在分词作宾补。
2-2 waving句意:当我接近23英里时,我看到我妻子在挥舞一个指示牌。她是我最大的粉丝。考查非谓语动词。see+宾语+ doing sth.看见……正在做某事。
2-3 riding句意:我钦佩地看到爸爸和保罗叔叔在骑马。他们看起来真的很酷。考查非谓语动词。此处需要用现在分词作宾补,意为“看见…正在做某事”。
2-4 taken句意:在非洲提供两年的医疗服务回来后,Lee医生很高兴看见家里的妈妈被照顾得很好。考查非谓语动词。his mother和 take good care of是被动关系,故用过去分词作宾语补足语。
2-5 being performed句意:在家里面听音乐是一回事,去听现场演奏完全是另一回事。考查非谓语动词。由于音乐是被演奏的,所以需要用被动形式,又因为是现场直播,动作是正在进行中的,所以用现在分词的被动形式。
