Structure,这里,if,所引导的是真实条件句,(real conditional),即所,假设的条件有可能成为现实,表达假定所假设的条件,实现时会出现的情况或会采取的行为。有时,我们,可以使用,并列结构的祈使句,来表达这种类型的条件句。,e.g. If you set your alarm clock, you wont oversleep.,如果你上闹钟,你就不会睡过头了。,Set your alarm clock, and you wont oversleep.,If you give him an inch, he will take a mile.,他会得寸进尺。,Give him an inch, and he will take a mile.,If you dont give him some food, he will starve.,如果你不给他一点吃的,他就会饿死。,Give him some food, or/else he will starve.,(1),条件状语从句通常由连词,if,引导,意为“如果、假如”,主句不能用,be going to,表示将来,而应该用,shall,、,will,。,e.g. If you leave now, you are never going to regret it.,(,错误,),If you leave now, you will never regret it.,(,正确,),(2) if “,如果”,引导条件状语从句,主句用一般将来时，,从句则用一般现在时，,如：,If it rains tomorrow, I shant climb the hills.,2.,用法,注意,:,宾语从句中的,if,与条件状语从句,if,的区别。,宾语从句中的,if “,是否”相当于,whether,引导,宾语从句,时态需根据语境确定。,I dont know,if,it will rain tomorrow.,我不知道明天是否会下雨。,在阅读英文文章时,我们有可能看到这样的句子：,If my father will give me permission, I shall spend a few,months abroad.,如果我父亲同意,我将在国外待几个月。,If you will take the trouble to read his letter carefully,you will see what he means.,如果你肯花一些时间来认真读他的信，你就会明白,他是什么意思了。,在,if-,分句中中用“,will,动词原形”并不单纯表示将来意义，,这里的,will,是个表示“意愿”的情态动词,相当于,be willing to,(,愿意,),。,要注意这种带“,will,动词原形”的,if-,分句在某些场合,是不可以随便用的,比如我们可以说：,If he gets my letter in time, hell be able to change,his plans.,如果他及时收到我的信,他就能改变他的计划。,却不可以说成：,If he will get my letter in time, hell be able to,change his plans.,另外,在,if-,分句,中还可能使用“,would,动词原形,”的结构，,这种用法还是表示“,意愿,”,常用于表示客气的请求,这时,主句动词既可以用,will/ shall,动词原形,也可以用,would/,should/ could/ might,动词原形。如：,If you would try Italian food, you would like it.,如果你愿意尝尝意大利食物,你会喜欢它的。,If you would reserve the seats, we would be sure of a,comfortable journey.,如果你愿意订座,我们将肯定会有一个舒适的旅程。,1.,如果你不赶快走,你就会迟到。,2 .如果你爱你的父母,你应当帮他们做做家务。,3. 如果你更友善一些,你会教上很多好朋友。,Exercise,If you dont go soon, youll be late.,You should help do the housework if you love your parents.,You will make lots of friends if you are more,friendly.,4.如果你带外校的朋友来,老师会让他们离开。,5. 如果你不完成作业,妈妈不会让你玩电游。,6.,当你看到,Bill Gates,你会对他说些什么？,If you bring friends from other schools, the,teacher will ask them to leave.,If you dont finish your homework, your mother,wont let you play computer games.,What will you say to Bill Gates when you see him?,For more exercises, click here.,1.,be,doing,形式,:,用现在进行时态表达将来，,主要意义是表示按计划、安排即将发生的动作，,常用于位置转移的动词,如,go,、,come,、,leave,，,start,、,arrive,等,也可用于其它动态动词。如：,The president is coming to the UN this week.,总统这周将到联合国来。,We are moving to a different hotel the day,after tomorrow.,我们后天将换一家宾馆。,Explanation,在现在英语中,有相当多的动态动词都可以用,现在进行时表示将来。,例如：,Dinner is ready. Were,having,fish for dinner.,晚饭好了,今晚我们吃鱼。,Im,spending,my holidays in Singapore this year.,今年我要去新加坡度假。,Tom isnt,finishing,his high school until next year.,汤姆明年才高中毕业。,advice,意为“劝告；建议”是,不可数名词,，不能说,a advice,而是,a piece of advice,也因为,advice,是不可,数名词。“两个（则）建议”，我们通常说,two pieces of advice,。注意,piece,要采用复数，,advice,不可数，但,piece,可数。我们也可以说为,some pieces of advice,一些建议。,如：,Can you give me some advice?,你能给我一些建议吗？,2.
