Step 4　问题探究
(　　)1.I have a lot of homework ________．
A．do　　B．doing　　C．did　　D．to do
答案选择D，本题考查动词不定式做定语，常常放在被修饰词之后，故正确答案为D选项。
(　　)2.If you have a headache，you should ________ a doctor.
A．see B．to see C．seeing D．saw
答案选择A，should意为“应该”，是情态动词，后面跟动词原形，所以答案选择A。
3．half的用法
(1)半个小时half__an__hour
(2)这个苹果一半是坏的Half__of__the__apple__is__bad.
(3)三个半小时three__hours__and__a__half/three__and__a__half__hours
half作形容词，意为“一半的”，一般要放在名词、代词之前。“half＋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。
half还可作名词，意为“半，一半”，其复数形式为halves。“……个半……”可表达为“数词＋名词＋and a half”或“数词＋and a half＋名词(复数)”。
