4. Can they go to the concert? 他们能去音乐会吗？

【难点】
使用Can you …？句型发出邀请并能正确回答。
1. I have to help my parents . 我不得不帮助我的父母。
I‟m sorry. I have to study for a math test. 对不起，我得为数学考试而学习。
(1)have to表示“不得不”的意思,“形势逼迫”的意味；help的用法：help sb with sth .或help sb (to) do sth . eg.
I have to help my parents with the housework .或说I have to help my parents (to) do the housework . 我不得不帮助我父母干家务。
You shall have to work hard if they want you to get it done this week.
如果他们要你这周完成这项工作的话,你就得努力工作。(表示外界条件的客观需要。) 而must则着重说明主观看法,表示个人的意志,eg.
I must go there to help the poor.
我必须去帮助那些穷人们。(表示说话人自己的看法。)
同时,在某些不需要强调这两种差别的场合,两者可以互相换用。eg.

(2)study for…表示“为……而学”的意思,for的后面接study的目的,eg.

That‟s too bad . Maybe another time . 太糟了，也许换个时间吧。
或Maybe next time . 也许下一次吧。
3. Thanks for asking . 谢谢你的邀请。
for是个介词不能直接跟动词 “ask”，所以动词变为动名词的形式 “asking”起到名词作
用。
Thanks for your photos . (photos为名词)
Thanks for helping me . (helping为动名词)
Thank you for your invitation to visit next week .谢谢你邀请我下周去做客。
4. I have a really busy week . 我有个实在忙碌的一周。
5. I‟m playing tennis with the school team . 我将同校队打网球。
6. finish the geography project in the evening . 在晚上完成地理作业。

8. come over to my house 到我家来
come over to表示从一个地方来到另一个地方。
come over还有“过来”“顺便来访”的意思
9.I have too much homework this weekend.
too much 用来修饰不可数名词,用来强调其“量”超出了正常的范围,eg.
He sometimes finds his teachers leave them too much work to do.
他有时认为老师留给他们的作业实在是太多了。
I don‟t want to eat too much food every day. 我不希望每天吃太多的东西。
too用来修饰形容词或副词,表示“太”的意思,其程度比very, so, quite要强得多。
10.Thank you for your invitation to visit next week.
(1)thank you for…“感谢……”，for表示原因，表示感谢的缘由，后须接名词、代词或动名词,。eg.
A thousand thanks for your kindness. 非常感谢你的善意。
Well, I must be going now. Thanks for your time. 我得走了，谢谢你为我花费了时间。谢谢你的邀请。
(2)名词invitation 来自动词invite,是在动词的后面加上后缀-tion或-ion构成,表示“情况,状态,性质,行为”等,如:quest—question, operate—operation等。
11. Please keep quiet! I‟m trying to study.
keep quiet 动词keep的用法很多,但主要意思基本不变,主要是“保存、保持”,表示持有的意思,具体用法有名词我们在家养了一条狗。
(2)keep+反身代词,eg.
I kept myself warm by walking up and down. 我踱来踱去以暖和身子。
(3)keep+sb/sth+形容词,eg.
The kettle is used for keeping water warm. 热水瓶是用来保持水温的。
(4)keep+动词-ing形式,eg.
They kept working for another half an hour. 他们又继续工作了半个小时。
(5)keep+sb/sth+动词-ing形式,eg.

【语法知识聚焦】
1. have to 与情态动词的区别
情态动词不能单独作谓语，后面必须接动词原形一起构成谓语，have to 也是这样。 情态动词没有人称和数的变化，而且所用的时态也受到一定的限制，但是have to 有人称和数的变化，可用于多种时态中，在一般现在时中，当主语是第三人称单数时，要用has to, 其余人称用have to；一般过去时中用had to；一般将来时中用will have to, eg. She has to go to school by bus. 她不得不乘公共汽车去上学。
If you get ill, you‟ll have to see the doctor. 如果你生病的话，你就得看医生。
2. have to 与must 的区别
have to 和must 都有“必须”的意思，那么它们有哪些不同呢？
(1) 含义和用法上的区别：
have to 强调客观上需要做某事，即表示外界条件的需要不得不做某事，含有“形势逼迫”的意味；must 强调说话者主观上认为必须做某事，含有“主观判断”的意味， eg. My bike was broken on my way to school. I had to walk there.
我的自行车在上学的路上坏了，我不得不走路去上学。（我本来不愿意走路，可是自行车坏了，不想走路也不行。）
We must learn English well. 我们必须学好英语。（主观上有这种想法。）
(2) 否定式的区别：
have to 的否定式意为“不必”，must的否定式意为“禁止；不允许”。因此，以must开头的一般疑问句的肯定回答为“Yes, 主语+must”，否定回答为“No, 主语+needn‟t / don‟t have to”。eg.
---Must I finish the homework now? 我必须现在完成作业吗？
---Yes, you must. (No, you needn‟t / don‟t have to) 是的，你必须现在完成。（不，你不必。）
3. 反意疑问句的构成区别：
(1) 陈述部分含有have to 时，其附加问句的谓语往往用助动词do的相应形式或助动词will。eg.
You had to go shopping yesterday, didn‟t you? 昨天你不得不去购物，是吗？
(2) 陈述部分含有must 时，其附加问句的谓语，按下面几种情况来确定：
A. must 意为“必须”时，附加问句谓语用needn‟t。eg.
We must clean the classroom, needn‟t we? 我们必须打扫教室，是吗？ B. mustn‟t意为“禁止”之意，附加问句谓语用must。eg. The boy mustn‟t play with the knife, must he? 那个男孩不能玩刀子，对吗？ C. must 意为“应该”时，附加问句谓语用mustn‟t。eg.
We must help each other, mustn‟t we? 我们应该互相帮助，对吗？
D. must 意为“一定；想必”表示推测时，附加问句部分谓语要根据must后面的动词来确定。eg.
Mr Liang must be at home, isn‟t he? 梁先生一定在家，对吗？
注：must 表示的是一种相当肯定的与事实非常接近的推测。eg.
Mr Wang must be at home. 其实就相当于Mr Wang is at home.
因此，它的反意疑问句的附加问句部分是isn‟t he 也就很容易理解了。
又如：They must be right, aren‟t they?
4.情态动词“have to”与其他的情态动词的用法比较：如“can” , “may”和 “should”（应该）。 而have to有。它的第三人称单数为“has to”，eg.
He should study hard . 他应该好好学习。
He has to study hard . 他不得不好好学习。
（2）这4个情态动词在一般疑问句中将它们提前大写，在否定句中直接在他们后边加not即可。（以can为例）
Can he go with us ? 他能和我们一起去吗？
而“have to”要加助动词do , does或did才可能完成其疑问、否定句。
同学们试着将下面三种话分别写成（1）一般疑问句，并做肯定回答。（2）否定句。 A: They have to go to the party . Do they have to go to the party ? Yes , they do . They don‟t have to go to the party .
B: He has to go to see the doctor . Does he have to go to see the doctor ? Yes , he does . He doesn‟t have to go to see the doctor .
C: She had to have a piano lesson yesterday . Did she have to have a piano lesson yesterday ? Yes , she did . She didn‟t have to have a piano lesson yesterday .
（用了助动词 “does”或 “did”表示疑问，否定时一定注意原来动词的第三人称单数或过去式要还原）

提示：
1. B, 表示在星期几，用介词 on。
2. A, have to 后面接动词原形。

4. tomorrow, 因为答句是Sorry, tomorrow I‟m playing soccer..., 由此判断得出答案。

1. have to 与情态动词的区别
情态动词不能单独作谓语，后面必须接动词原形一起构成谓语，have to 也是这样。 情态动词没有人称和数的变化，而且所用的时态也受到一定的限制，但是have to 有人称和数的变化，可用于多种时态中，在一般现在时中，当主语是第三人称单数时，要用has to, 其余人称用have to；一般过去时中用had to；一般将来时中用will have to, eg. She has to go to school by bus. 她不得不乘公共汽车去上学。

2. have to 与must 的区别
have to 和must 都有“必须”的意思，那么它们有哪些不同呢？
(1) 含义和用法上的区别：
have to 强调客观上需要做某事，即表示外界条件的需要不得不做某事，含有“形势逼迫”的意味；must 强调说话者主观上认为必须做某事，含有“主观判断”的意味， eg. My bike was broken on my way to school. I had to walk there.
我的自行车在上学的路上坏了，我不得不走路去上学。（我本来不愿意走路，可是自行车坏了，不想走路也不行。）
We must learn English well. 我们必须学好英语。（主观上有这种想法。）
(2) 否定式的区别：
have to 的否定式意为“不必”，must的否定式意为“禁止；不允许”。因此，以must开头的一般疑问句的肯定回答为“Yes, 主语+must”，否定回答为“No, 主语+needn‟t / don‟t have to”。eg.
---Must I finish the homework now? 我必须现在完成作业吗？
---Yes, you must. (No, you needn‟t / don‟t have to) 是的，你必须现在完成。（不，你不必。）
3. 反意疑问句的构成区别：
(1) 陈述部分含有have to 时，其附加问句的谓语往往用助动词do的相应形式或助动词will。eg.
You had to go shopping yesterday, didn‟t you? 昨天你不得不去购物，是吗？
(2) 陈述部分含有must 时，其附加问句的谓语，按下面几种情况来确定：
A. must 意为“必须”时，附加问句谓语用needn‟t。eg.

We must help each other, mustn‟t we? 我们应该互相帮助，对吗？
D. must 意为“一定；想必”表示推测时，附加问句部分谓语要根据must后面的动词来确定。eg.
Mr Liang must be at home, isn‟t he? 梁先生一定在家，对吗？
注：must 表示的是一种相当肯定的与事实非常接近的推测。eg.
Mr Wang must be at home. 其实就相当于Mr Wang is at home.
因此，它的反意疑问句的附加问句部分是isn‟t he 也就很容易理解了。
又如：They must be right, aren‟t they?
4.情态动词“have to”与其他的情态动词的用法比较：如“can” , “may”和 “should”（应该）。 而have to有。它的第三人称单数为“has to”，eg.
He should study hard . 他应该好好学习。
He has to study hard . 他不得不好好学习。
（2）这4个情态动词在一般疑问句中将它们提前大写，在否定句中直接在他们后边加not即可。（以can为例）
Can he go with us ? 他能和我们一起去吗？
而“have to”要加助动词do , does或did才可能完成其疑问、否定句。
同学们试着将下面三种话分别写成（1）一般疑问句，并做肯定回答。（2）否定句。 A: They have to go to the party . Do they have to go to the party ? Yes , they do . They don‟t have to go to the party .
B: He has to go to see the doctor . Does he have to go to see the doctor ? Yes , he does . He doesn‟t have to go to see the doctor .
C: She had to have a piano lesson yesterday . Did she have to have a piano lesson yesterday ? Yes , she did . She didn‟t have to have a piano lesson yesterday .
（用了助动词 “does”或 “did”表示疑问，否定时一定注意原来动词的第三人称单数或过去式要还原）
