4 、It seems that/as if...
　　本句型實際上是“主＋系＋表”結構，其中it是無人稱代詞，本身并無詞意，也并非形式主語，seems為系動詞，that/as if...引導表語從句，本句型使that/as if引導的從句所表達的意思變得不大肯定或者使語氣變得較為委婉。
　　例：①It seems that it is more difficult for women to get to the top of the company. 婦女似乎更難提升到公司的最高職位。

　�、贗t seems to me that he has known everything.
　　(He seems to have known everything) 看來他似乎什么事都知道了。
　�、跧t seems as if it is going to rain.
　　(It seems to rain) 看來天要下雨了。
　　It seems(that...)�？梢杂肐 guess that...來替換。
　　例：①I guess men’s hands and fingers are too big !
　　It seems that men’s hands and fingers are too big. 男人的手和手指似乎太大了。
　�、贗t seems that she told a lie in order to get a job in our company.
　　I guess she told a lie in order to get a job in our company. 看來她為了想在我們公司找一份工作，向我們撒了謊。

　　5、 have sb./sth. doing sth.
　　此句型中，have為使役動詞，分詞短語在句中作賓語補足語，與賓語之間是主動關系，意為“使某人(某物)做某事”，強調動作的持續性。
　　例：①We have never had women working in this part of our company before. 我們以前從來沒有讓女人在我們公司的這個部門工作。
　　②They had their lights burning all night long. 他們通宵把燈點著。
　　如果只強調讓某人、某物做某事而不強調動作的持續性時，我們可用省“to”的不定式在句中作賓語補足語。
　　例：I won’t have you do such things. 我不讓你去做這些事。
　　當使役動詞have后接過去分詞短語，作賓語補足語時，賓語則與補足語之間是被動關系，即have sth. done句型， 此句型有兩種含義。
　　其一：表示“使得某事得以做成”或“(請人)把某事做完”。
　　例：①I’ll have my bicycle repaired. 我將把自行車推去修好。
　�、贗 had my hair cut yesterday. 我昨天去理了發。
　　其二：表示“遭遇某種情況”或“經歷一個事情或行動”。
　　例：①King Charlies I had his head cut off. 國王查理一世被砍了頭。
　�、赟he had her wallet stolen yesterday. 昨天她的錢包被偷了。
　　
　　6、 Does it matter...
　　此句型中，it為無人稱代詞，作主語，matter是動詞，意思是“關系重要”，主要用于否定句，疑問句和條件狀語從句中。
　　例：①Does it matter if an engineer is a man or a woman? 工程師是男是女，這有什么關系呢？
　�、赪hat does it matter? 這有什么關系？
　�、跧t doesn’t matter, does it ? 這沒多大關系，是嗎？
　�、躀t doesn’t matter to me what you do or how you do it. 你做什么，怎么做對我都無關緊要。
