问几道高中非谓语动词的英语题 希望附有讲解1.______ in the mountains for a week,the two students were finally saved by the local police.A.having lost B.lost C.being lost D.losing2.It is worth condering what makes "convenience " foods so popular,and ______ better ones of your own.A.introduces B.to introduce C.introducing D.introduced这句话还请翻译一下3.---Can those ______ at the back of the classroom bear me?---No problem.A.seat B.sit C.seated D.sat

1 lost一方面是lose的过去分词及过去式，一方面又是一个单独的形容词。那么在这道题中，其要是为过去分词，则译为“丢失',这个主语应为人，宾语应为物，但此处显然不行。故只能为形容词，译为“迷路的',可直接放在句首，不用加其他修饰词，选B
2 “什么使得方便食品如此受欢迎是值得考虑的，并且介绍几个你认为好的”主要考虑前半句话和后面是并列的还是分开的，如并列，则要和前面用一样的形式，这道题就是，故选C
3 可以判定此处应填一个定语，而seat是及物动词，故用被动形式，选C

A B C --那些坐在教室后面的同学可以接纳我么？--没问题

1.______ in the mountains for a week,the two students were finally saved by the local police.
A.having lost (= the the two students had lost)
不可选.表示早于被警察救出,但是 lose 是及物动词,后面有 themselves 才可以成立.
B.lost(= the the two students were lost )
可选.be lost 表示迷路.
C.being lost (= the the two students were losing )
不可选.既表示被警察救出同时发生,有没有宾语 themselves.
D.losing (= the the two students lost )
不可选.表示曾经丢失过某种东西（但没有宾语）,与警察救援没有关系.
2.It is worth condering what makes "convenience " foods so popular,and ______ better ones of your own.
答案：C.introducing
it is worth 后带有两个并列的动名词,其他形式不符合结构要求.
即：It is worth condering ...and introducing ...值得考虑...并采用.
这句话还请翻译一下
3.---Can those ______ at the back of the classroom bear me?
---No problem.
答案：C.seated
1）seated at the back of the classroom 是过去分词短语用作后置定语,等于定语从句 who are seated at the back of the classroom ,注意 seat是及物动词,意思是“使...就座、被安排就座”,所以定语的意思是“使他们就座于教室后面的（那些人）”
2）句子主体是：Can those hear me?那些人听得到我（讲课吗?）
3）sit/sat 是不及物动词,指的是行为者的具体动作,用在此处不对.
翻译：坐在教室后面的那些人听得到我吗?
