(1) We believe we must increase our export sales if we want to continue to grow, and we hope to increase exports to 15 – 20 percent of production, with your help.

A: We hope to increase our export sales by 20% with your help.

B. We must increase our export, hoping to reach 15% to 20% of production.

老师：答案是B， 我选择了A，为何A不正确呀？

解答：A 和 B 的区别本质上是 increase to 与 increase by 的区别：前者到增长到多少，后者表示增长了多少。A的意思是：我们希望在你的帮助下将出口销售增长20%；B的意思是：我们必须增加出口，并希望达到15—20%的产量。显然符合原意的是 A，而不是B。

(2) We were sorry we were late for the meeting yesterday. If we had not had a flat tyre, we would have arrived on time at 2:30 instead of at 3:30. We came an hour later than we should.

老师，这句话中的than 在这里怎么翻译呀？这句话我没看懂。

解答：这是一个比较句型，其中的 than 就是表示“比”，这个句子的完整说法是：

We came an hour later than we should have arrived.

很抱歉我们昨天开会迟到了。如果我们的车没有爆胎，我们就不会3:30才到，而是会在2.30就到达了。我们晚到了一个小时。

类似的例子如：

Janet wired me to say she’d be here a day later than planned.  珍妮特发电报给我，说她要比计划晚一天到这里。

(3) Eeverything i made belonged to me.

老师，请问这里为何用belonged，而不是make to do的结构呢？

解答：这里的 I made 是定语从句，修饰 everything，意思是：我做出来的所有东西都属于我的。
