關(guān)閉窗口 as 用作連詞有哪些用法
as 用作連詞用法如下：
一、表示伴隨
意為“隨著”。如：
As time passed, things seemed to get worse. 隨著時(shí)間的推移，情況似乎變得更糟了。
若其后不接從句，而接名詞，則用介詞 with 表示“隨著”。如：
With the development of modern agriculture and industry, more and more waste is produced. 隨著現(xiàn)代工農(nóng)業(yè)的發(fā)展，污染越來越嚴(yán)重了。
二、表示讓步
意為“雖然”“盡管”，要用于倒裝句（相當(dāng)于 though，但語(yǔ)氣稍弱）。如：
Boy as he was, he behaved like a girl. 他雖然是個(gè)男孩，但舉止卻像個(gè)女孩。
Much as I like you, I couldn’t live with you. 我盡管很喜歡你，卻不能和你一起生活。
Try as he would [might]，he couldn’t open the door. 他試過多次了，卻仍打不開門。
三、表示時(shí)間
意為“當(dāng)……時(shí)候”。如：
He dropped the glass as he stood up. 他站起來時(shí)，把杯子摔了。
As I was coming here, I met your brother. 我來這里時(shí)碰到了你的弟弟。
注意，as 引導(dǎo)時(shí)態(tài)狀語(yǔ)從句時(shí)，其謂語(yǔ)動(dòng)詞通常只能是動(dòng)作動(dòng)詞，而不能是靜態(tài)或狀態(tài)動(dòng)詞。如：
她出生后不久父母雙亡，是由姑母撫養(yǎng)大的。
誤：Her parents died as she was a baby and she was brought up by her aunt.
正：Her parents died when she was a baby and she was brought up by her aunt.
四、表示原因
引導(dǎo)原因狀語(yǔ)從句時(shí)，其謂語(yǔ)動(dòng)詞可以是動(dòng)作動(dòng)詞，也可以是狀態(tài)動(dòng)詞。如：
As you weren’t there I left a message. 因?yàn)槟悴辉谀抢铮伊袅藗�(gè)信兒。
另外，引導(dǎo)原因狀語(yǔ)從句，可用以下這樣的倒裝語(yǔ)序。如：
Tired as she was, I decided not to disturb her. 因?yàn)樗哿耍揖蜎Q定不打擾她了。
Writing hurriedly as she was, she didn’t notice the spelling errors. 因?yàn)閷懙脗}(cāng)促，她沒有注意其中的拼寫錯(cuò)誤。
