三. 重難點解析:
1. 情態動詞have to 的用法,意思是"必須、不得不",它側重于客觀上的必要和外界的權威。(1)結構:主語+have to+動詞原形+其他
(一般現在時,主語是第三人稱單數時,用has to;句子是過去時,用had to.)如: we have to wear sneakers for gym class. 在體育課上,我們必須穿運動鞋。tom has to practice the guitar every day. 湯姆每天必須練習彈吉它。i had to get up at 5:00 am last monday. 上周一,我不得不早上5點起床。
(2)否定形式:主語+don't have to+動詞原形+其他
(一般現在時,主語是第三人稱單數時,用doesn't have to. 句子是過去時,用didn't have to)
如:nick doesn't have to wear a uniform. 尼克不必穿制服。we didn't have to do our homework at once. 我們不必馬上完成作業。
(3)疑問句:do (does或did)+主語+have to +動詞原形+其他
如:do you have to stay at home on weekends? 周末你必須呆在家里嗎?yes, i do. / no, i don't.
是的,我必須。不,我不必。did he have to go to bed by 11:00 last night? 昨晚,他不得不11點前上床睡覺嗎?
2. 情態動詞can的用法
(1)表示能力,"會能"(在第一冊中已經學習這種用法)
can you play the guitar? 你會彈吉它嗎?judy can speak a little chinese. 朱蒂會說一點中文。i can dance and sing. 我能唱歌又能跳舞。
(2)表示允許、許可,"可以"、"能"(在這一課中新學的詞義)
can the students run in the hallways? 學生們可以在走廊上跑嗎?we can eat outside. 我們可以在外面吃東西。can i come in? 我能進來嗎?
注意 同樣是情態動詞,can 和have to 的用法是有區別的,和大部分情態動詞一樣,can在否定句中,直接在can后加上not,在疑問句中,把can放到主語前面,并且沒有人稱和數的變化。
3. hear,listen和sound都有"聽"的意思,但三者是有區別的。
(1)hear"聽說",側重于"聽"的內容
i'm sorry to hear that you are ill. 聽說你生病了,我很難過。
i never heard such an interesting story. 我從來沒聽過這么有趣的一個故事。
