二．重点句型的用法

1.(教材P26)There Daisy saw an antelope looking sad. 在那儿戴茜看到一只羚羊，神情沮丧。

(1)I saw him work in the garden yesterday. 昨天我看见他在花园里干活了。(强调过程) I saw him working in the garden yesterday. 昨天我看见他正在花园里干活。(强调动作) 2.

(教材P26) It shows the importance of wildlife protection, but I'd like to help as the WWF suggests. 这体现了野生动植物保护的重要性，不过，我还是想按照世界野生生物基金会的建议来帮助(你们)。

as sb. suggests 正如某人所建议那样

句法分析：

as表示“像……那样；如……”，引导方式状语从句。suggest意为“建议”，

suggest doing sth建议做某事；suggest接从句时有两种语气，作“建议”讲时，从句谓语多用“should＋do”结构，作“暗示，表明”讲时，后面从句用一般语气。
