題目：

they would like it to be 後面的to be 可以省略嗎?爲什麼要加to be 能不能改成 they would like to
原句是It is important because the world will always be more difficult and complicated than they would like it to be .

解答：

不可以省略.
1、你首先要弄清楚不定式的省略.在口語中,爲了避免重複,常常會省略不定式結構中和句子前面的部分重複的動詞原形,而只留下動詞不定式符號to.這類動詞主要是表示心理,情感,計劃等的動詞或短語,如 expect,want,plan,intend,try,hope,wish,love,hate,decide,refuse,like,prefer,forget,would like,would love等,如：Mary wanted to use your new bike,but I asked her not to.又如—Will you come for a walk?—I『d love to.
2、其次你要弄清,當不定式含有be 或是動詞的完成式時,be 和have 都不可以省略.如：
①—Is Tom a student?—No,but he used to be.
②—He hasnt finished yet.—Well,he ought to have.
此句中的「be」是和上文的「 be more difficult and complicated 」呼應的,如果上文用的不是be動詞而是行爲動詞become的話,那不定式後面就可以省略其他成分.
3、表示希望、想的時候可以用 would like to do sth ,would like sb.to do sth.但在這個句子中不是他們自己想怎樣,而是他們想要這個世界怎樣,所以代指world的it也不能省.
