正确答案是B
英语这样描述有半的数量的;
(1.) 数词+and a half +单位s 如:two and a half hours 要注意单位后加 s
(2.) 数词+单位(s) +and a half 如 two hours and a half 注意:这里单位是否加s 要看其前的数词是否大于一,所以也可以说 one hour and a half .
B
英文中对数量的这种描述习惯:
X.5单位的东西
X+(单位) and a half
X and half a (单位)
Afive kilos and half Bfive kilos and a half
Cfive and half kilos Dfive and half a kilo
A 5000 再加一半也就是共7500
B5000再加上一千的一半=5500
C 同B
D 同BC.
所以要选A
five kilos and a half
或者
five and a half kilos
这是英语表达上的问题，一般就是数量词+单位
有half 的时候要用成a half
答案B
因为因为five是复数啊。要加s。但是half就不是，之前要加定冠词a。
B半小时,不加S.half an hour.
