7、为“主将从现”。主句的将来时态并不仅限于我们这一课里所学习到的will动词原形构成的一般将来时, 还包括begoing to动词原形、be doing所表示的一般将来时以及我们以后会学到的其它的将来时态。例如:What is he going to do when he grows up?他长大了想干什么？We are leaving for Amoy tomorrow if it doesnt rain如果明天不下雨, 我们就去厦门。We will buy that microwave next week if its pricekeeps going down.如果价格持续下降, 下个礼拜

9、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.

10、od, or/else he will starve.2. 用法(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.E

13、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.总统这周将到来。We are moving to a different hotel the dayafter tomorrow.我们后天将换一家宾馆。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 ye

14、ar.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。2. Can you give me some advice please?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
