1.虚拟语气的考点:与过去事实相反的时候,表达假设用情态动词加现在完成时态;
2.现在进行时的被动语态,结构是:be动词+being+动词过去分词意为:正在被做.全句的意思是:为了拯救那个小女孩,很多事情正在被人们做;
3.must的否定式表示严禁和一定不要的意思,所以c答案是错误的.Must表示必须,它的反义词应该是不必要,因此needn’t就可以了;
4.现在完成时的被动语态,结构是:have/has+been+过去分词.By now已经很明确的暗示这个句子应该用现在完成时了,意为“到目前为止”.
5.一般将来时的被动语态,结构为will/shall+be+过去分词.这句中的next week已经是将来时态的范畴了,加之动词的关系是被动,故选c.
6.正确答案应该是is known!这是个一般现在时的被动语态.中国的长城被全世界所知,这个事实是真理性的,不必考虑其他时态,一般现在时足以.
7.含有情态动词的被动语态,根据语气来讲,should表示应该,合适题目的意图.后面加上be动词的原形和动词过去分词.
8.动词搭配的考点.Get/have something+过去分词表示“让别人去做某事”.故选答案b.
