II. Language points
Section A
1. I fed some sheep.我喂了一些羊。
sheep n. “绵羊”它是单复数同形的单词, 当它作主语时谓语动词的单复数形式要根据它在句中的意思来确定。类似的单词还有deer (鹿), Chinese (中国人)等。如：
看! 树下有三只羊在吃草,一只小绵羊在阳光下玩 。
Look, there are three sheep eating grass under the tree.
2. —Who visited her grandma? 谁去看望了她的奶奶？
—Becky did. 贝姬去了。
答语中的did代替了问句中的visited her grandma。英语中为了避免不必要的重复，经常使用do, does, did, so等来代替前面的动词或相关内容，其时态要与问句中的时态保持一致。
eg. -- Who likes singing ? 谁喜欢唱歌？
-- Tom does. 汤姆喜欢唱歌
He didn't go camping,but I did.
