18、是一個(gè)完整的句子,肯定要有主語；2if 從句的位置本模塊我們接觸的都是“ if從句 +祈使句 ”的句子； if 引導(dǎo)的條件從句表示“假如 ” ,條件狀語從句可置于祈使句前或后,如上面的例句；也可以放在主句之后；e.g.Print the photo if you like it. 假如喜愛這張照片就把它打印出來；Look at our website if the camera does not work. 假如相機(jī)出故障就到我們網(wǎng)站上查看；Tell him to make a phone call to me if he comes here tomorrow. 假如他明天來這兒的話,叫他給

20、 off the sports meeting. 假如明天下雨, 我們就推遲運(yùn)動會；if 在上句引導(dǎo)的是條件狀語從句,盡管從句中也有表將來時(shí)的時(shí)間狀語 tomorrow,從理論上講也應(yīng)當(dāng)用一般將來時(shí),但是在 if 引導(dǎo)的條件狀語從句中要用一般現(xiàn)在時(shí)代替一般將來時(shí),故從句謂語動詞用 rains 而不用 will rain. 一、單項(xiàng)挑選：1I can hardly hear the radio.
