If itdoesntrain, we will go to the park next Sunday. 如果天不下雨，下周星期天我们将去公园。 2. If you ask him，he will hel

2、p you如果你求他，他将会帮助你。 二、if作为连词还可以引导宾语从句。引导宾语从句时和whether意思相同。例如： 1. Lily asked if whether she liked it. 莉莉问她是否喜欢它。 2. She asked if whether they had a cotton one 她问是否他们有一件棉织的。3.I dont know if it will rain tomorrow. 三、用于虚拟语气中，if从句中用过去式，表示不可能实现，大概不会实现或提出作为考虑的假定条件。例如： 1. If you were a bird, you could fly.假使

3、你是只鸟，你便会飞了。 2. If I asked him(if I were to ask him) for a loan，would he agree?如果我向他借贷，他会答应吗? 另外，if从句中用过去完成式，表示过去未实现的条件(例如由于不可能实现或某人之未能实行)。例如： 1. If they had started earlier，they would have arrivedin time要是他们早些动身，他们便可及时到达了。 2. If they had not started when they did，they would not be here now如果他们那时不动身，

4、现在他们就不会在此地了。 第三，在文学体栽中，if有时可省略，然后将主语与所用的限定动词(尤其是were，had，should)倒置。例如： 1. Should it (=if it should)be necessary，I will go. 倘若有必要，我会去的。 2. Were I(=if I were) in your place，I would do the same 如果我处于你的位置，我也会这样干的。 3. Had I(=if I had)known earlier，I would come如果我早一点知道，我就会来。四、if与其它一些介词的连用。 首先，as与if连用，它的意思

5、是：“仿佛、好像”同样引导从句。例如： 1. It isnt as if we are rich(We are not rich)我们不像富有的样子。(即我们不富有) 2. It isnt as if he doesnt know the ruler(ieHe does know the rulers)他不像不懂规则的样子。(即他懂得规则) 五.另外as if还可以引导感叹句。例如： As if I would allow it!(ieI would certainly not allow it!)好像我会答应似的!(我才不会答应哩!) 其次, if与only连用。常表示愿望或一个未实现的条件

6、，尤其用于感叹句中。例如： 1. If only he arrives in time!他若能及时到达就好了! 2. If only she would marry me!但愿她能嫁给我！ 3. If only she had known about it!（But she didnt know.） 她那时要是知道（但她不知道）这事就好了!一、连词的定义 * 连接词与词、短语与短语、句子与句子的词，叫连词。例如：* It is neither too cold nor too hot in spring.（neithernor连接两个词）* You can read either in the

7、 morning or in the afternoon.（eitheror连接两个短语）* Hu Lan was late yesterday because she woke up too late. （because连接两个句子）二、连词的种类和常考连词的用法* 从连词本身的含意及其所连接的成分的性质来看，可分为两类：并列连词和从属连词。* 一）并列连词。用来连接有并列关系的词、短语或分句的连词是并列连词；并列连词连接分句构成并列句。（一） 常用来并列同类性质的词与词、短语与短语的并列连词and,or, neither.nor,either.or,not only.but also, b

8、oth.and：* 1. and 和，并且* My uncle lives and works in Shanghai. 我叔叔在上海居住和工作。* He's big and tall. 他很高大。* 2. or 或（非否定句中）、和（否定句中）* Are you a teacher or a student? 你是老师还是学生？* You can take some food or some money. 你可以带点吃的或带点钱。* I dont like reading or writing. 我既不喜欢读，也不喜欢写。* 3.either.or, 要么要么，或者或者*

10、我的女儿不仅能唱，还会跳。*（二） 常见的并列分句构成并列句的连词有and，or，but，so* 1. or 否则 相当于一个否定条件句。* Hurry up, or youll be late. 快点，否则你就要迟到了。* (If you don't hurry up, you'll be late.)* 2. and这样的话，就会，相当于一个肯定条件句* Study hard, and you can get good grades.努力学习，你就会取得高分。* (If you study hard, you can get good grades.)* 3. but 但是

11、，可是，而 前后分句是转折关系* Mr Mott is very poor, but he feels happy.

12、that用于引导陈述句的宾语从句，可以省去，如：* She says that she likes watching TV very much.* 2). when, where, who, why, what等连接副词连接由特殊疑问句转化过来的宾语从句。如：* Do you know when the train arrives?* Can you tell me where you come from?* 3). if, whether连接有一般疑问句转化过来的宾语从句。 * They are wondering if they can get the money back.* She a
