新概念英语第一册的课程中,语法部分涵盖了多个核心知识点,旨在帮助学习者掌握英语的基础语法结构和表达方式。在Lesson 135 "The latest report"中,讲解了几个关键点:
1. **加强语气的副词"really"**:在句子中,"really"用来强调形容词或副词,例如"I may. I can’t make up my mind."这句中的"really delicious"加强了对葡萄酒味道的好评。
2. **动词短语"make up one’s mind"**:意为“拿定主意,做出决定”。例如"They made up their minds to sell the house."表示他们决定出售房子。
3. **"let sb do sth"结构**:允许某人做某事,等同于"allow sb to do sth"。如"Her parents wouldn’t let her go out with that boy."
4. **"introduce sb to sb"**:将一个人介绍给另一个人,例如"May I introduce my sister to you?"
5. **"get married"和"be married"的区别**:"get married"指的是结婚的行为,而"be married"则表示已婚的状态。例如询问对方婚姻状况的问句和答句:"Are you married?" "When did you get married?" "I got married last year." "How long have you been married?" "I have been married for 14 months."
6. **直接引语与间接引语的转换规则**:
- 当直接引语是客观事实时,间接引语保持原时态,如"The moon moves round the earth."
- 如果直接引语是一般过去时并伴随具体时间,间接引语仍用一般过去时,如"She said she went to England in 1998."
- 主句为现在时,间接引语时态不变,如"He says he bought me a book yesterday."
7. **指示代词、时间状语、地点状语和动词的变化**:在转换直接引语为间接引语时,这些元素可能需要相应调整,例如"here"变为"there","yesterday"变为"the day before","today"变为"that day","this"变为"that","tomorrow"变为"the next day","these"变为"those","ago"变为"before"。
8. **句式转换**:
- 陈述句变为间接引语,通常用"that"连接,有时可以省略,如"She said that she was a girl."
- 一般疑问句、选择疑问句和反意疑问句转为间接引语,用"if"或"whether"引导,并使用陈述语序,如"She asked me if I was Mr. Li."
- 特殊疑问句转换,保留特殊疑问词,改为陈述语序,如"Susan asked her husband how much they had spent on petrol that year."
- 祈使句转为间接引语,通常用"ask/tell sb (not) to do sth"结构,如"She asked me to come early."
通过学习这部分内容,学生能够更好地理解和运用英语中的基本语法结构,提升语言表达能力,为日后的英语学习打下坚实基础。
