Step 8　Language points

1. Grandpa, did people go fishing a long time ago？

爷爷，很久以前人们钓鱼吗？　

go fishing表示“去钓鱼”。英语中当go之后接表示“运动，娱乐”的动

词时，一般用动词-ing形式，构成“go＋动词-ing”，表示“去做……”。go swimming去游泳        go boating去划船

go skating去滑冰           go shopping去购物

2. Our people always went fishing and hunting for food.　

我们的人一直通过钓鱼、打猎获取食物。

hunt作动词，意为“打猎;搜索”。

The tigers always hunt alone.老虎总是单独猎食。

【辨析】hunt for，search for与look for

①hunt for 指寻找或搜寻难找到的东西。

②search for 侧重于指仔细搜索、搜寻某人或者某物。

③look for 强调寻找一些失去的东西，侧重于寻找的过程，与hunt for 作“寻找”时同义。

②take 常指“花时间”。常用句型： It takes sb. some time to do sth.做某事花了某人多少时间。

4. And they ate good, natural food like fish and vegetables.

词。其名词形式为nature(自然)；副词形式为naturally(自然地)。

这个地区的自然景色非常美丽。

5. Some people played the drums and others danced around the fire.

  一些人击鼓，另一些人围着火堆跳舞。　

some...others...表示“―些……另一些……”。其中others前没有定冠词the，只表示“另一些”，而非剩余全部。如果其前有the，则表示特定范围内剩余的全部。
