句型梳理
1. Last month we asked our students about their free time activities.上个月，我们询问了学生们关于他们的业余活动的情况
要点精析

例 :I ask my teacher about today's homework.
【拓展】
Ask sb.(not)to do sth，为“要求某人(不要)做某事”

ask for“要求;请求”，其宾语是物;ask sb for sth.意为 “向某人要某物”
You can as ask for help from the policeman.你可以向警察求助
2. Here are the results.这是(调查)结果
要点精析
这是以here开头的倒装句，其主语是 the results，here 为表示地点的副词。
【拓展】here/there/now/then 等副词置于句首，谓语动词是连系动词 be 或come，go等不及物动词，且主语是名词时，其后的主语和谓语颠倒位置，构成倒装结构，这种倒装句的真正主语是后面的名词，如果主语是代词，句子主谓不倒装。
例:Here is a letter for you.这是给你的一封信
Here comes the bus.公共汽车来了
3. We found that only fifteen percent of our students exercise every day.我们发现只有 15%的学生每天锻炼

find+宾语+宾补，意为“发现某物......“这一结构中的宾语补足语可以由现在分词、过去分词、名词、形容词、副词、介词短语以及动词不定式等来充当。
