三. 重難點解析：
1. 情態(tài)動詞have to 的用法，意思是"必須、不得不"，它側(cè)重于客觀上的必要和外界的權(quán)威。（1）結(jié)構(gòu)：主語＋have to＋動詞原形＋其他
（一般現(xiàn)在時，主語是第三人稱單數(shù)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(xí)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(xiàn)在時，主語是第三人稱單數(shù)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(yè)。
（3）疑問句：do （does或did）＋主語＋have to ＋動詞原形＋其他
