If it doesn't rain tomorrow, we will go shopping. Grammar 14 You will get good grades if you study hard. 如果你努力学习，就会取得好成绩。 Unless you get up early, you’ll not catch the school bus. If it doesn't rain tomorrow, we will go shopping. 如果明天不下雨，我们将去购物。 You can pass the exam if you study hard.如果你努力学习，你就会通过考试。 二、条件状语从句的引导词。 条件状语从句通常由连词if(如果；假如)，unless(＝if…not, 除非；如果不)，as long as (只要）引导。 三、条件状语从句的位置。 条件状语从句既可以放在主句之前，也可以放在主句之后。如果放在主句之前，要用逗号与主句隔开；如果在主句之后，中间不必用逗号。 Grammar 15 四、条件状语从句的时态。 1.由if引导的条件状语从句，如果主句用一般将来时, 从句则用一般现在时，即应遵循“主将从现”的原则， 如：If it rains tomorrow, I shan’t climb the hills. If she comes to see me tomorrow, I’ll be happy. If Sam doesn’t work hard, he will fail his exams. 2. 如果主句含有must /can/may 等情态动词，从句要用一般现在时。 You must stop if the traffic light is red. 3.如果主句是祈使句， 从句也常用一般现在时。 Please stay at home if it rains tomorrow. If you eat bad food, you may fall ill. If you want to win, please work hard. Grammar 16 【拓展】 1. if还可以表示“是否”，相当于whether, 用于引导宾语从句。 I don't know if he come tomorrow. If he comes, I will tell you.(前一个if表示“是否”，后一个if表示“如果”。) 2. unless(相当于if...not, 除非，如果不), as long as(只要)也可以引导条件状语从句。 3.“with+ 宾语或without＋宾语”，有时可以改成条件状语从句。 If there is no water, fish will die. If you don’t work hard, you’ll fail the exam. =You’ll fail the exam unless you work hard. = You can’t drive the car if the door is open. = Fish will die without water. You can’t drive the car with the door open. Grammar 17 =Work hard, or you won’t pass the exam easily. 4.if引导的条件状语从句可以转换为：祈使句＋and＋另一个句子；如果if引导的条件状语从句是否定句，可转换为：祈使句＋or＋另一个句子。 If you work hard, you’ll pass the exam easily. =Work hard, and you’ll pass the exam easily. Grammar 18 Fill in the blanks. 1. If you exercise more, you ______ (be) much healthier. 2. If it ______ (rain) tomorrow, they _________ (not play) soccer after school. 3. You should see a dentist if you _____ (have) a toothache. 4. If he _____ (walk) to school, it ________ (take) him too much time. will be won’t play have walks will take rains 5. If you ________ (not go) to bed earlier, you _______ (feel) tired in the morning. 6. If it __________ (not rain), he ________ (play) basketball with me tomorrow. 7. If Uncle Ian ______ (come), I ________ (call) you up. 8. Please wake me up if he _______ (come) back. doesn’t go will feel doesn’t rain will play comes will call comes Grammar 19 Grammar Focus What did you find out? I think I’ll take the bus to the party. If you do, you’ll be late. I think I’ll stay at home. If you do, you’ll be sorry. What will happen if they have the party today? If they have it today, half the class won’t come. Should we ask people to bring food? If we ask people to bring food, they’ll just bring potato chips and chocolate. if引导的条件状语从句替代词do的用法。 条件状语从句中的do,是替代词，代替上文中的动词短语，为避免重复,条件状语从句常用助动词do(does/did)来替代上文所提到的动作。take the bus to the party, stay at home.上边两句可以写成：If you take the bus to the party, you’ll be late. If you stay at home, you’ll be sorry. Grammar 20 Grammar Focus What did you find out? I think I’ll take the bus to the party. If you do, you’ll be late. I think I’ll stay at home. If you do, you’ll be sorry. What will happen if they have the party today? If they have it today, half the class won’t come. Should we ask people to bring food? If we ask people to bring food, they’ll just bring potato chips and chocolate. 情态动词should的用法。 should为情态动词，意为“应该；应当”，后接动词原形，无人称和数的变化。 Grammar 21 （2）should表示要求或命令。 You shouldn’t talk in class. （3）should表示预测或可能。 His school bag should be in the classroom. (4) 基本句式 肯定句：sb. should +动词原形. Maybe he should say sorry. 否定句：sb. shouldn’t +动词原形. You shouldn’t smoke in the hospital. 一般疑问句：Should sb.+动词原形?

You will see some tall buildings. → If you go to visit New York City, you’ll see some tall buildings. 1. a. You think you’re going to study English hard. b. You will do better in English. → If you study English hard, you’ll do better in English. 2. a. You think you’re going to eat and drink more. b.
