both和all的用法區別
薛立新導師:both和all的用法區別
一、both 指兩個人或物,可構成“both…and… ( 兩者都…… ) ”句型;all 指三個或三個以上的人或物。例如:
1.There are many trees on ___ sides of the road.
A.either B.both C.each
2.My full name is Jim Allen Green.Green is my family name.
___ of my other names were given by my parents.
A.All B.Some C.Each D.Both
3.___ of the students in our class wantto go to plant trees.
A.Either B.All C.Neither D.each
4.He has got two pens,and ___ of them are expensive.
A.both B.either C.each D.every
二、要注意 all 和 both 在句中的位置,它們兩個都用於 be 動詞之後,實義動詞之前。例如:
5.My parents ___ fine.What about your family?
A.both are B.all are
C.are all D.are both
6.They are all students.他們都是學生。
7.We both study English.我們倆都學英語。
三、both 作主語時,謂語動詞用複數,當 all 作主語時,表示“整體事物”,其後謂語動詞應用單數;表示“所有的人 ( 物 ) ”,謂語動詞用複數。例如:
8.He answered two questions and both were right.
他回答了兩個問題並且都正確。
9.All has gone well.一切進展順利。
10.All are here.大家都來了。
四、both 和 all 在否定句中並不表示全部否定,而表示部分否
定,要表示全部否定,要用它們相對應的詞:both 的全部否定詞
爲 neither,all 的全部否定詞爲 none。例如:
11.Mr black has two danghters.___ of them is a doctor.
A.None B.Both C.Neither D.No one
12.Theyareallverytired,but ___ ofthemwouldtakearest.
A.any B.some C.none D.neither
