20、f 意為“如果”，由它引導的條件狀語從句表示假如有從句的動作發(fā)生，就會有主句的某個動作發(fā)生。從句可以放在主句之前或之后；當從句位于主句之前時，須用逗號與其隔開。如：If I go there，Ill take her some flowers. / Ill take her some flowers if I go there. 如果我去那兒，我將給她帶些花。3. 在if引導的條件狀語從句中，如果主句是一般將來時，從句用一般現(xiàn)在時代替一般將來時,這種現(xiàn)象叫做“主將從現(xiàn)”。如：Well stay at home if it rains tomorrow. 如果明天下雨，我們將待在家里。二、二、i

22、cant live. 如果沒有水，我們就不能生存。We cant live without water. 沒有水我們不能生存。三、三、if引導的從句還有一些其他需注意的方面：引導的從句還有一些其他需注意的方面：1. 當主句是祈使句或者含有情態(tài)動詞時，條件狀語從句仍然用一般現(xiàn)在時表示，因為不論是祈使句還是含有情態(tài)動詞的句子都可以表示將來的動作。如：Please call me if you go shopping next Sunday. 如果下周日你去購物，請給我打電話。We may go out if its fine tomorrow. 如果明天天氣好的話，我們可能會出去。2. if 引導
