Task 3: Report like this
Do you like… 是一个一般疑问句, 它表示询问对方是否喜欢某物。
句中 do的是助动词, 没有意义。回答时, 肯定回答用do,
否定回答用don’t。
(2) 如果主语是第三人称单数形式, 助动词 用does, 其句型为：
--Does he /she like…
--Yes, he/she does. / No, he/she doesn’t.
1. --Do you like salad 你喜欢沙拉吗？
--Yes, I do. / No, I don’t .是的, 我喜欢。/ 不, 我不喜欢。

--Yes, he does. / No, he doesn’t. 是的,他喜欢。/ 不, 他不喜欢。
e.g. I don’t like bananas. 我不喜欢香蕉。
He doesn’t like apples. 他不喜欢苹果。
e.g. Can I have a cup of orange juice, please 我可以要一杯橘汁吗？
I like oranges better than tomatoes. 与西红柿比, 我比较喜欢橘子。
2. I like bananas. 我喜欢香蕉。
(1) like表示“喜欢”, 是动词。如果主语是第三人称单数, 后要加“s”。
e.g. He likes apples. 他喜欢苹果。
(2) 否定形式要在like前加don’t或在likes 前加doesn’t, 同时把likes改为like。
3. Do you like oranges
orange n. 既可以是可数名词, 也可以做不可数名词。当可数名词时,
意思是“橘子”; 当不可数名词时, 意思是橘汁。
