1.half
half的用法与all和both相同,既可用作形容词（或称限定词）修饰名词,如 half the year, half the work, half the fruit，亦可用作不定代词,受of短语修饰,如：half of the work, half of the year, half of the fruit。这两种表达形式在意义上没有明显的区别。
例如：Half (of) the girls are foreigners. 这些姑娘有一半是外国人。
)
half +名词或half of+名词作主语时,谓语动词的单、复数形式由所接名词的单复数形式来决定,名词是中心词
eg:Half (of) the fruit was bad. 水果有一半是坏的。
Half(of) my friends live in this city. 我的朋友有一半住在这个城市。

2.much rather
much rather 是有点反面的讲，“我更宁愿”
eg:I'd much rather watching The Voice of US.
much prefer 是正面，“我喜欢”

3.five tenths
five tenths是十分之五的意思。
分数的表达方式用“基数词＋序数词”表示。其中基数词表示分子，序数词表示分母。
要注意如果分子大于1，分母要用复数形式。
比如：two thirds，三分之二。而三分之一则用one third.
