人教版新目标八年级上Unit3单元总结与练习
【重点解读】
both意为“两者;两者都”,只能用来修饰两个人或事物。
both用作形容词,放在复数名词前做定语;
用作代词时,往往和of构成短语both of;
用作副词时,往往置于be动词、助动词或情态动词之后,行为动词之前。
【例句展示】
1.Both sisters are outgoing and generous. 姐妹俩都外向又慷慨。
2.Both of the teachers are teachers and writers. 这两个老师既是老师又是作家。
3.Millie and Grace are both good at dancing. 米莉和格蕾丝两人都擅长跳舞。
【拓展延伸】
both直接修饰名词时,不加of。若是添加了of,则要在名词前加上适当的限定词。
Both children went to study abroad for further education.
Both of the (my) children went to study abroad for further education.
(我的)两个孩子都去国外继续深造了。
both放在人称代词前时,一定要用both of,不能说 both we或 both us,但可以说us both, them both等。
Both of us went to the movies last night. 昨晚我们两个去看电影了。
both与not连用,是部分否定,表示“两者不都…”,其否定形式是neither。
Both the doors are not open. 两扇门并不都开着。
如果要将上述例句改成全部否定,则就应写成:
Neither door is open. (= Neither of the doors is open.) 两扇门都没开。
both…and…是“两者都;又……又;不但……而且”的意思,在句中起连接作用,可以用来连接各种并列成分,甚至两个句子。
Both Lucy and Lily are secretaries of big companies. 露西和莉莉都是大公司的秘书。
