老师答疑
陈老师：
How soon will you come back?
In about ( )
A one and a half months
B a month and a half
C one and half a months
该题选A
结构为：数词+and +a half +名词复数
结构为：数词+and +a half +名词复数=数词+时间名词+a half
one and a half hours=one hour and a half
two and a half hours=two hours and a half
What would you like to have for breakfast?
( ) and some cakes.
A A half glass of milk
B Half a glass of milk
C Half milk
该题选B
half + a+名词
例如：
half a year
half an hour
half a bowl of rice
half a month
曾老师：
1.英国人表达“一半”的数量一般用half an hour, half a dozen…等，不定冠词“a/an”放在half之后；表达一个数量单位时，不定冠词放在half之前而且在half与数量单位词之间加连字号“-”，如：a half-dozen半打, a half-year半年, a half-apple半个苹果。
2.但在美国英语中，无论是表示数量还是单位都不加连字符。如：a half year, a half dozen, a half apple。在意思上与英国人的表达并无区别。
3.“一个半小时”为an/one hour and a half或one and a half hours；“两年半”为two years and a half或two and a half years，但前一种说法更为常见。
4.half表示“半小时（三十分钟）”，不用冠词。如：at half past five 在五点半；It is half past seven.七点半了。
5.与介词in搭配用half，与介词into搭配用halves（in halves的搭配非常少见）。例如：
I cut the cake in half (或into halves). 我把蛋糕切成了两半。
6.half与all和both类同（前位限定词），位于定冠词、物主代词或指示代词前修饰名词（如 half the year, half my work, half those apples），也可作不定代词与of短语搭配（如half of the work, half of the year, half of the fruit）。这两种表达在意义上没有明显区别。如：
Half (of) the migrant workers are from Sichuan. 这些农民工有一半是来自于四川。
Half (of) the fruit was bad. 这些水果有一半是坏的。
黎老师：
How soon will you come back?
In about ( )
A one and a half months
B a month and a half
C one and half a months
【答】one and a half后面应该接复数名词(《牛津英语用法指南》第三版有例句)，所以该题选A是正确的，C one and half a months 是错误的。但是，B a month and a half也是正确的，类似例句：A year and a half has passed.(摘自英国出版的 A Comprehensive Grammar of The English Language)
What would you like to have for breakfast?
( ) and some cakes.
A A half glass of milk
B Half a glass of milk
C Half milk
【答】《牛津英语用法指南》第三版指出：“half 通常用在冠词 a/an 之前，但在量度词语中也可以放在 a/an 之后。Could I have half a pound of grapes?（或 ... a half pound ...）请给我称半磅葡萄。”所以，该题选B或者A A half glass of milk都是正确的。
在表示时刻“......点半”的 half past ...结构中，不用冠词。
