(二)核心语法(重点考点)
1. 情态动词should/shouldn’t的用法(核心重点)
• should(应该):表示建议、责任或义务,用于肯定句和疑问句;shouldn’t(不应该):否定形式,表不建议;
肯定句:主语 + should + 动词原形 + 其他(如:We should keep a healthy diet to stay away from illness.);
否定句:主语 + shouldn’t + 动词原形 + 其他(如:We shouldn’t eat too much junk food.);
疑问句:Should + 主语 + 动词原形 + 其他?(回答:Yes, 主语 + should. / No, 主语 + shouldn’t.)(如:Should we do exercise every day? Yes, we should.);
• 拓展:should 还可表示委婉的建议,语气比must更温和(如:You should take your temperature first when you feel hot. 你觉得热的时候应该先量体温。)。
2. 一般现在时(第三人称单数)(重点)
• 当主语是第三人称单数(he, she, it, 单数名词、不可数名词)时,谓语动词要加-s/-es;
肯定句:主语(三单) + 动词-s/-es + 其他(如:She takes her temperature every morning. / He keeps a healthy diet every day.);
否定句:主语(三单) + doesn’t + 动词原形 + 其他(如:He doesn’t eat junk food very often.);
疑问句:Does + 主语(三单) + 动词原形 + 其他?(回答:Yes, 主语 + does. / No, 主语 + doesn’t.)(如:Does your father do exercise every day? Yes, he does.)。
3. 一般过去时(重点)
• 表示过去发生的动作或存在的状态,谓语动词用过去式;
肯定句:主语 + 动词过去式 + 其他(如:I did some running in the playground yesterday afternoon.);
否定句:主语 + didn’t + 动词原形 + 其他(如:She didn’t keep a healthy diet last week.);
疑问句:Did + 主语 + 动词原形 + 其他?(回答:Yes, 主语 + did. / No, 主语 + didn’t.)(如:Did you take your temperature yesterday? No, I didn’t.)。
4. 不定式to do表目的(核心重点)
• 表示“做某事的目的”,结构为“主语 + 动词 + 其他 + to do sth.”(如:I do exercise every morning to keep strong. 我每天早上做运动是为了保持强壮。);
• 常见搭配:take a walk to keep fit(散步来保持健康)、do yoga to stay healthy(做瑜伽来保持健康)、make a plan to keep healthy(制定计划来保持健康)。
5. 形容词辨析(易错点)
• healthy(形容词,健康的)vs health(名词,健康):healthy修饰人或事物,health作主语或宾语(如:He is healthy. 他很健康。We should care about our health. 我们应该关注我们的健康。);
• sick(形容词,生病的)vs ill(形容词,生病的):sick可作定语和表语,ill只能作表语(如:a sick boy 一个生病的男孩;He is ill. 他生病了。)。
(三)重点句型(高频考点)
1. 建议句型:主语 + should/shouldn’t + 动词原形 + 其他.(某人应该/不应该做某事。)(如:We should drink more warm water every day. 我们应该每天多喝温水。)。
2. 询问方式句型:How do you stay healthy?(你如何保持健康?)(回答:I + 动词原形 + ... to stay healthy. 如:I do exercise every day to stay healthy.)。
3. 询问动作句型:What did you do to stay healthy yesterday?(你昨天做了什么来保持健康?)(回答:I + 动词过去式 + ... to stay healthy. 如:I took a walk to stay healthy yesterday.)。
4. 感受描述句型:It makes me + 形容词.(它让我感到……。)(如:Doing exercise every day makes me strong and energetic. 每天做运动让我感到强壮且精力充沛。)。
5. 拥有某物/方式句型:主语 + have/has + 某物/方式.(某人有某物/某种方式。)(如:She has many ways to stay healthy. 她有很多保持健康的方式。)。
6. 固定句型:It’s + 形容词 + to do sth.(做某事是……的)(如:It’s important to keep a healthy diet. 保持健康饮食是很重要的。)。
7. 原因表达句型:主语 + be + 形容词 + because of + 名词/动名词.(某人因为……而……。)(如:She was sick because of eating too much junk food. 她因为吃太多垃圾食品而生病了。)。
