Language points
1、Last month we asked our students about their free time activities.上个月，我们询问了学生有关课余活动的问题。（P13）
ask sb. about sth.意为“向某人询问有关……的情况”。
Yesterday I asked some students about pop music.
考点拓展 ask sb. for sth.意为“向某人要某物”；ask sb.to do sth.意为“要求/请求某人做某事”，其否定结构为ask sb. not to do sth.，意为“要求/请求某人不要做某事”；ask for寻求。
He went to ask the policeman for help.他去向那个警察求助。She asked me to lend her some money.她请求我借些钱给她。
Language points
2、Here are the results.以下是结果。（P13）
这是一个倒装句，即“Here+谓语十主语”句式，其中的主语由名词充当，谓语动词的形式要与后面的主语的数保持一致。
这里有你一张票。Here is a ticket for you. 公共汽车来了。Here comes the bus.
注意 如果此句式中的主语为代词时，就要用“Here十主语+谓语”句式，即不完全倒装（主语在前，谓语在后）。
Here it is.它在这儿。
Language points
3、...，but we were surprised that ninety percent of them use the Internet every day.……，但是让我们惊讶的是，他们中有90%的人每天使用网络。（P13）
surprised 意为“感到吃惊的”，后面可接动词不定式或that从句。be surprised to do sth.表示“对做某事感到惊讶”；be surprised at sth.表示“对某事感到惊讶”。（以上结构都是人做主语）
考点拓展 surprising表示某物或某事本身令人惊讶，物做主语或surprising在句中做定语。
中考特殊考点 surprise做名词，意为“惊奇，诧异”。to one's surprise使某人感到惊讶的是；in surprise惊讶地，惊奇地，修饰动词。
令他惊奇的是，他发现这个女孩是个盲人。
To his surprise, he found the girl was blind.
Language points
4、Although many students like to watch sports, game shows are the most popular.虽然许多学生喜欢看体育节目,但游戏类节目是最受欢迎的。（P13）
Although作连词，意为“虽然，尽管”，用于引导让步状语从句，语气
比较强，可放于句首或句中，有时可与though 互换。
Although he was tired, he went on working. 尽管他很累，他仍然继续工作。He often helps me with my English although/though he is quite busy.尽管他相当忙，但他常常帮我学英语。
although/ though引导的让步状语从句不能与but连用，但可以与yet, still连用。
Language points
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.通过上网或观看游戏类节目放松是有好处的，但我们认为，放松的最好方法是通过锻炼。
①句型“It is/was +adj (for sb.)+to do sth.”中，it是形式主语，真正的主语是动词不定式短语to do sth.。该句型的意思是：“（对某人来说）做某事.....的”
It’s+adj. +for sb.+to do sth. 该句式常用于表示事物的特征、特点。形容词常为表示客观情况的形容词，如：easy, hard, difficult, interesting, impossible等 It’s very hard for him to learn two languages.对他来说学两种语言是很难的。
It's+adj. +of sb.+to do sth. 该句式常用于表示人物的性格、品德。形容词常为表示主观感情或态度的形容词，如：good, kind, nice, clever, foolish等 It’s very nice of you to help me.你来帮助我，你真是太好了。
Language points
②“by+v.-ing”构成的短语可做行为、方式状语。by后接名词、代词、动名词形式，表示“通过某种方式、手段做某事”。
他以教书为生。He made a living by teaching.
6、The answers to our questions about watching television were also interesting.对我们提出的有关看电视的问题的回答也颇有意思。（P13）
the answer to the question问题的答案。介词to表示“关联，联系”。
阅读这篇短文，并找出这个问题的答案。Read this passage, and find out the answer to this question.
考点拓展 类似表达：the key to the door门的钥匙；a ticket to去……的票。（以上to的用法多在完形填空中考查）
Language points
7、...,but we think the best way to relax is through exercise.但是我们认为放松的最佳方式是通过锻炼。
through exercise通过锻炼，through表示通过某一途径做某一件事情。
考点拓展 through prep.通过，穿过，经过。词组look through表示“查看，浏览”。
I saw it through the window.我透过窗户看见了它。
考点辨析 cross，across，through，over
（1）cross是动词“（从表面）穿过，越过，渡过”，可直接接宾语。They crossed the road.他们穿过了马路。
（2）across指从这边到那边“通过，横过”，含义与on有关，动词 walk/go/run/swim等+across=cross，常和street，bridge，river等连用。We swam across the river.我们游到河对岸。
Language points
（3）through“穿过，通过”，强调从内部“穿过”，含义与in有关，如：穿过森林、城市、窗户等。The thief got in through the window.小偷是通过这扇窗户进来的。
（4）over越过….指从上方跨过。The girl can't jump over the pole.这个女孩跳不过这横竿。
8、It is healthy for the mind and the body.它有益于身心的健康。（P13）
mind做名词时，意为“头脑；心智”，做动词时，意为“介意”。
固定搭配
含mind的短语 change one'smind 改变主意
make upone's mind 下定决心
keep in one'smind 牢记.……
Never mind. 不必担心。/没关系。
Language points
中考特殊考点 “Would /Do you mind （not）doing sth.？”和“Would/Do you mind+人称代词宾格或形容词性物主代词+doing sth.？”表示“你介意某人干某事吗？”
Would you mind closing the door？你介意把门关上吗？
9、And remember，“old habits die hard”. 请记住：旧习难除。（P13）
die v. 消失；消灭；死亡
①作“死亡”讲，是短暂动词，不能与表示一段时间的状语连用。
②dead 死的，是die的形容词形式。可作表语或定语。作表语时，表示状态，可以与表示一段时间的状语连用，替代动词die。
③die可以用于进行时态，表示“即将死去，奄奄一息”。
④death 死亡，是die的名词形式。
　中考特殊考点 die是非延续性动词，不能同表示一段时间的状语连用。如果表达“死了多长时间”，用“have /has been dead for+时间”或“died+时间段+ago”
Language points
10、Exercise such as playing sports is fun, and you can spend time with your friends and family as you play together.像进行体育活动这样的锻炼很有趣，而且当你和朋友、家人一起运动时，你们还可以共度时光。（P13）
such as意为“诸如……的；像……这样的；例如”，接动词时用动名词形式。
I have lots of interests, such as singing, dancing, drawing and so on.
考点拓展 for example也表示“例如”，一般是以同类事物或人中的一个为例，做插入语，不影响其他部分的语法关系。
生活中充满难题。例如我们就有些家庭问题。Life is full of problems. For example, we have some family problems.
