1、连接词:用来连接两个或两个以上词或句子的词。
注意:英语中一般不能同时使用两个连接词,如不能说:Although he is very rich, but he is not happy.
关于连接词的使用,详见第三讲:句子的连接一节。
2、冠词:用来限定名词的词,分不定冠词a 和定冠词 the, 英语中的冠词使用十分复杂,简单地说:
1) 不可数名词前不能用a
2) 第一次提到的单数可数名词用a
3) 能用what, who, which回答的名词用the,即3W原则
the teacher and the student / the patient and the doctor结构中的the可以表示泛指
词性不是一成不变的,是由其在句子中的位子和功能决定的。
如:She has gone home.
Is she at home?
She looked at me patiently. She looked pale.
