34、這里不能用for但是說：She was angry, for she didnt know French. 她生氣了，因為她不懂法語。這里用for是正確的，也可用because注意：之所以有這些用法上的限定，其理由是for引導(dǎo)的從句不能直接說明*一特定動作發(fā)生的原因，而只能提供一些起幫助解釋作用的附加說明。例如：The days were short, for it was now December. 天短了，現(xiàn)在已是12月了。He took the food eagerly, for he has eaten nothing since dawn. 他狼吞虎咽地吃了起來，因為他從天亮就沒吃過

51、我找人來幫助。Never trouble trouble till trouble troubles you. (諺)不要無事惹事。帶有until狀語從句的主句謂語有何特點請看看這道題：We _ until he came. A. stoppedB. arrivedC. leftD. waited此題應(yīng)選D。選項A，B，C都有可能被誤選。要弄清此題需弄清以下幾點：1. until 意為“一直到，其相應(yīng)主句的謂語只能是持續(xù)性的，而不能是終止性的。它表示的是：主句動作一直持續(xù)到從句動作發(fā)生時為止。以上一題的A，B，C選項是錯的，主要是因為其含義荒唐：假設(shè)選A，句意為：我們一直在停頓，直到他來就不停

52、頓了。假設(shè)選B，句意為：我們一直在到達，直到他來就不到達了。假設(shè)選C，句意為：我們一直在離開，直到他來就不離開了。以上各句的意思顯然不通。選D是對的，因為其意為：我們一直在等，直到他來就不等了(即我們一直等到他來)。2.上面說到，與 until 從句連用的主句謂語不能是終止性動詞，但是假設(shè)這個謂語是否認(rèn)的，則可以是終止性動詞，因為終止性動詞一旦被否認(rèn)，即成為狀態(tài)，而狀態(tài)都是可以持續(xù)的(注：not.until.意為：直到才)：誤：We stopped until he came. 正：We didnt stop until he came. 直到他來我們才停頓。誤：We started unti

53、l the rain stopped. 正：We didnt start until the rain stopped. 直到雨停我們才開場。誤：He finished it until it was dark. 正：He didnt finish it until it was dark. 直到天黑他才完成。3、 表示“一就的時間連詞。主要的有as soon as, the moment, the minute, the second, the instant, immediately, directly, instantly, once, no soonerthan, hardlywhen
