1. If you do, the teachers won’t let you in. 如果主句用了一般将来时, 那么以 if 引导 的条件状语从句要用一般现在时来替代 一般将来时。 if 引导的条件状语从句既 可放在主句之前, 也可放在主句之后；放 在主句之前时, 要用逗号与主句隔开。例 如：

If it doesn’t rain tomorrow, we will go to the park. = We’ll go to the park if it doesn’t rain tomorrow. 如果明天不下雨，我们就去公园。 let sb. in 意为 “ 允许某人进入 ” ， in 是副词， 意思是 “ 在里面、向里面 ” ，作宾语补足 语。

2. OK, when is a good time to have the party? 动词不定式 to have the party 在句中作 定语, 修饰名词 time 。动词不定式作定语 时, 一般要放在所修饰词的后面。例如： Do you have anything to say? 你有什么要说的吗？ He was the last one to arrive. 他是最后一个到的。

3. let’s 是 let us 的缩写, 意思是 “ 让我 们 ”, 后接动词原形。 e.g. Let’s have a rest. Let’s not go out. 4. half 一半的 e.g. Half the workers come from Shanghai.

Grammar focus I think I’ll ride my bike. If you do, you’ll be late. I think I’m going to stay at home. If you do, you’ll be sorry. I think I’m going to wear jeans to the party. If you do, the teachers won’t let you in. I think I’m going to the party with Ann. If you do, you’ll have a great time.

Explanation 1. if 条件句 条件状语从句中的 “ 主将从现 ” 现象, 即 主句为将来时态时, 它所引导的条件状 语从句使用一般现在时表达将来的意 味, 这时主句和从句所表达的时态在意 义上仍然保持一致。

构成条件从句主 句 时态 If ＋一般现在时 主语＋ shall/will + 动 词原形 例句 If he comes, he will take us to the zoo.

如 : If he goes to England, he will have to learn English. 如果他要去英格兰, 他将不得不学 英语。 If it is fine tomorrow, we will have a picnic somewhere. 如果明天天气好, 我们就到什么地 方野餐去。

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。

如 : If you set your alarm clock, you won’t oversleep. 如果你上闹钟，你就不会睡过头了。 Set your alarm clock, and you won’t 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 don’t 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.

在 if 分句中用 “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, he’ll 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, he’ll 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。

2. 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。 在现在英语中, 有相当多的动态 词都可以用现在进行时表示将来。

如 : Dinner is ready. We’re having fish for dinner. 晚饭好了, 今晚我们吃鱼。 I’m spending my holidays in Singapore this year. 今年我要去新加坡度假。 Tom isn’t finishing his high school until next year. 汤姆明年才高中毕业。
