动词不定式(短语)作表语时，一般情况下不定式符号t不能省略，但当主句主语部分含有实义动词d的某种形式时，可省略作表语的动词不定式（短语）里的不定式符号t:
1.The imprtant thing is 　　　　　　　　(finish) the wrk n time. 2.The engine just wn’t start.Smething seems 　　　　　　　(g) wrng with it. 3.The purpse f new technlgy is t make life easier,nt 　　　　　(make) it mre difficult. 4.(2020·浙江卷)The easiest way t accmplish this is 　　　　　(make) sure yu cnduct yurself as a gd neighbur shuld. 5.What I wuld suggest is 　　　　　(put) ff the meeting. 
1. 动词不定式和v-ing作表语时，要注意与句子的主语在形式上保持一致，即若句子的主语为v-ing，则表语也应使用v-ing；若主语为动词不定式，则表语也应使用动词不定式。T see is t believe. = Seeing is believing.
动词不定式作表语和v-ing作表语的区别
2. 动词不定式和v-ing作表语时可换用，但以下情况除外:(1) 当动词所表达的是某一特定的行为，尤其是将来的行为或有待于实现的行为时，通常用动词不定式作表语。 Her best wish is t put her new ideas int practice.
(2) 若动词所表达的并不强调动作，而是表示主语的内容，则通常用v-ing作表语。My favrite sprt is swimming.What I hate mst is being laughed at.
1. The Olympic Games, ___ in 776 B. C., didn’t include wmen until 1912. 　A. first playing B. t be first played C. first played D. t be playing
简析: 首先,根据语法分析可知,待选部分是一个作定语、修饰 The Olympic Games的后置分词短语;再根据 The Olympic Games 对于动词 play 来说只能是被动承受,且已完成 (in 776 B. C.)。因此,该题应选C。
2. What’s the language ___ in Germany? A. speaking B. spken C. be spken D. t speak 简析: 该题应选B。测试过去分词作后置定语表达被动,等于定语从句 which is spken。
3. Mst f the artists ____ t the party were frm Suth Africa. A. invited B. t invite C. being invited D. had been invited 简析: 该题应选A。测试过去分词作后置定语表达被动, 等于定语从句wh were invited。
4. The cmputer centre, ___ last year, is very ppular amng the students in this schl. A. pen B. pening C. having pened D. pened 简析: 该题应选D。测试过去分词短语作定语放在所修饰的名词后,可以用非限制性定语从句“which was pened last year”代替。
5. The first textbks ____ fr teaching English as a freign language came ut in the 16th century. A. having written B. t be written C. being written D. written 简析: 该题应选D。测试过去分词作后置定语表达被动,等于定语从句which were written。
6.The murderer was brught in, with his hands ___ behind his back. A. being tied B. having tied C. t be tied D. tied 简析: 很显然,待选部分的逻辑主语是 his hands,而不是句子的主语 The murderer,而 his hands 对于动词 tie来说,只能是被动承受。因此,该题应选D。
另外,分词作状语时,如果其逻辑主语与整个句子的主语不一致时,需要独立主格结构或 with 复合结构来替代。(此时,也可把该分词看成介词的宾语补足语。)
7. When _____ if she wuld request a rise, the actress said that mney was nt imprtant. A. asked B. asking C. having asked D. being asked
