五、Language points
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
Ask sb aboutsth意为“问某人关于某事的情况”
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”
My mother asked me to clean the room.我妈妈要求我打扫房间。
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
要点精析
find 意为“找到，发现:碰上”，可指无意识或经过寻找后发现。有如下用法
后接名词或代词
例:You'llfind the answers at the back of the book.你将在书后找到答案
后接that 从句
例:I find that it pays to be honest.我发现为人诚实有益
可以带双宾语，双宾语交换位置时用介词 for。
例:Please find me my key=Please find my key for me请帮我找到我的钥匙
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。
例:What activity do youfind enjoyable 你发现什么活动有趣 (形容词作宾补)
4. The answers to our questions about watching television were also interesting.对我们提出的关于看电视的问题的回答也很有意思。
要点精析
the answers to...questions 为固定搭配，意为“......问题的答案/回答”
to在此为介词，意为“指向;对于;针对”
类似的短语还有: the key to the door门的钥匙;
The solution to the problem这个问题的解决办法
例:Can you find out the answers to the questions 你能找出这些问题的答案吗
5. It is good to relax by using the Internet or watching game shows,but we think the best way to relax is through exercise. 通过上网或看游戏类节目来放松很好，但是我们认为最好的放松方式是通过锻炼。
要点精析
句型"It+be+adi+to do...”中it为形式主语真正的主语是to do因为主语大长
为避免头重脚轻，要把它放在后面
【拓展】
It+be+adj.( +or sb.)+动词不定式+其他
这类句型常用形容词easy，difficult.，hard,important，possible 等作表语，有时
候为了强调动词不定式动作的执行者，常在动词不定式前加for sb.

年轻人掌握两门外语是有必要的。
It+be+adi.+ofsb.+动词不定式+其他
这类句型常用表示人的品质，性格特征的形容词，如:kind，nice，stupid， clever, foolish, polite ,impolite , silly , selfish, considerate 等
