(1)half of后也可接代词，这时of不能省略。

(2)half还可以作名词，意为“一半；半”，
其复数形式为halves。

代词或“疑问词+不定式”结构。

else修饰疑问代词或不定代词，置于被修饰词之后。
other修饰名词，置于名词之前。语法解读I. if引导的条件状语从句/第一条件句if意为“如果；假如”，可用来引导条件状语从句。带有条件状语从句的句子属于复合句，从句表示主句动作发生的前提或条件。
1.结构：if+陈述句, 主语+谓语 / 主语+谓语+if+陈述句
意为“如果......就......”

=We will go hiking, if it is fine tomorrow.
2.时态：在主句和条件状语从句中的动词都表示将来的动作时，主句常用一般将来时，从句常用一般现在时，即“主将从现”。3. if引导的条件状语从句可以转换为“祈使句A, and+句B”。

=Try your best to do it, and you will find it easy.
如果if引导的条件状语从句是否定句，可以转换为“祈使句, or+句B”。
If you don't study hard, you won't get good grades.
=Study hard, or you won't get good grades.II. 情态动词shouldshould作情态动词，有实际的词义，但它不可单独作谓语，须与动词原形连用，没有人称和数的变化。其否定形式为shouldn't；变为一般疑问句时，should提到主语之前。
