上海牛津版英语六年级第一学期6A期末复习的知识点涵盖了多个语法和词汇主题,对于学生来说是重要的复习材料。以下是一些关键知识点的详细解释:
1. 频度副词:如always(总是)、sometimes(有时)、usually(通常)、never(从不)。这些词用来表达动作发生的频率,询问频率时用"How often?",例如:"How often do you go swimming?",回答可以是:"Twice a week."。
2. 介词:包括地点和方位介词,如near(近)、far(远)、arrive in/at(到达),以及leave(离开)。如"I live near school.","He will leave Shanghai.","arrive in Shanghai","arrive at the airport"。
3. 方位词:如east、west、north、south以及它们的组合,用来描述方向和相对位置。例如:"Beijing is north of Nanjing.","Heilongjiang is on the north of Jilin.","Beijing is in the north of China."
4. 代词:one用于指代单数的人或物,ones用于复数。例如:"One book"对应用"ones books"。
5. 定冠词the的使用:在球类运动前不加定冠词,如"play football",而在乐器前必须加上,如"play the piano"。此外,观看球赛时也不加定冠词,如"watching television"。
6. 数词和量词:a few修饰可数名词,如"a few eggs";a little修饰不可数名词,如"a little milk"。
7. 位置系动词be后的副词:如"She is always kind.",行为动词前的副词如"She always helps other people.",但要注意避免在一个句子中同时出现两个动词。
8. how often与how many times的区别:how often询问频率,如"How often do you exercise?",而how many times询问具体次数,如"How many times have you been there?"。
9. 副词的用法:副词可以修饰形容词、动词、其他副词或整个句子,例如"He looks very happy.","The old lady is walking slowly now.","Luckily, he got the first prize."
10. 一次、两次、多次的表达:once表示一次,twice表示两次,三次及以上用数字+times,如"three times"。
11. 介词的分类与用法:如with表示伴随,接宾格,如"I'll go there with Jim.";on用于表示具体楼层,如"On the first floor.";on也用于表示具体日期,如"On Sunday morning"。
12. some, a lot of, plenty of的用法:这些词既可修饰可数名词也可修饰不可数名词,如"some eggs", "a lot of milk", "plenty of eggs"。
13. some和any的差异:some常用于肯定句,any用于否定句和疑问句,例如"I have some new books.", "Do you have any new books?", "I don't have any new books."
14. too many, too much, too few, too little的用法:这四个词分别修饰可数名词复数、不可数名词,表示过多、过少。
