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。
