— She plays it once a week. 她每周打一次。

三、 核心语法精讲
【重点1】频率副词
1. 常见频率副词(按频率高低排序):always (100%) > usually > often > sometimes > never (0%)。
2. 句中位置:通常位于 be动词、助动词之后,实义动词之前。
She is always busy. (be动词后)
I usually go to school by bike. (实义动词前)
They don't often eat out. (助动词后,实义动词前)
3. 对频率提问:使用 How often...?。
How often do you visit your grandparents? Once a month.
【重点2】情态动词 Should 的用法
用于提出建议或劝告,语气较 must 缓和,是中考高频考点。
1. 肯定句:主语 + should + 动词原形...
You should drink more water.
2. 否定句:主语 + shouldn't + 动词原形...
We shouldn't watch TV for too long.
3. 一般疑问句:Should + 主语 + 动词原形...?
Should I eat before exercise? Yes, you should. / No, you shouldn't.
4. 与 must, have to 的辨析(巩固):
must:强调“必须”(主观/客观)。
have to:强调“不得不”(客观要求)。
should:强调“应该”(建议、劝告)。
【重点3】可数名词与不可数名词(在饮食话题中的运用)
1. 不可数名词(无复数形式,不能与a/an直接连用): milk, water, juice, bread, rice, fish(鱼肉),meat, junk food。
表达数量需借助量词:如,a glass of milk, two bowls of rice。
2. 可数名词(有复数形式): apple(s), vegetable(s), egg(s), hamburger(s)。
I eat an apple every day. We need to buy some vegetables.
四、 中考能力拓展与易错点提示
1. How often 的回答:需用表示频率的短语,如 every day, three times a week, once a month, hardly ever(几乎不)。
2. Good 与 Well 的辨析:
good 是形容词,修饰名词或放在系动词后:good food, It tastes good.
well 通常作副词,修饰动词:eat well, sleep well。作形容词时仅指“身体好”:I'm well.
3. “对…有好处/坏处”的表达:be good/bad for...
Exercise is good for your health. Smoking is bad for you.
4. “想要做某事”的表达:want to do sth. would like to do sth.
5. 写作升级:在提出建议时,避免全部使用 You should...,可交替使用 It's a good idea to..., Why not...?, Don't forget to..., Remember to... 等,使语言更丰富。
