英语语法：cost,pay,spend的用法“五辨”
英语语法：cost,pay,spend的用法“五辨” 一、辨主语 虽然三者均可表示“花费”，但所用主语不同：cost 的主语通常 是事或物(包括形式主语 it)，不能是人;spend 的主语只能是人，不 能是事或物;take 的主语能够是事或物(包括形式主语 it)，也能够是人。如： The computer cost (me) $2000. 这台电脑花了(我) 2000 美元。 It costs $1000 a year to run a car. 使用一辆车每年要花 1000美元。 I have spent all day looking for you. 我花了一整天找你。 It took me an hour to write the letter. 我写这封信花了一 个小时。 The letter took me an hour (to write). (译文同上) I took an hour to write the letter. (译文同上) 注：若 cost 不是表示“花费”，而是表示客观上地或被动地 “耗费”，则也可用人作主语。如： Smokers cost the government a lot of money every year. 抽 烟的人每年要耗费政府很多钱。 二、辨宾语 cost 的宾语通常是钱，take 的宾语通常是时间，而 spend 的宾 语则能够是时间或钱。如： How much did it cost to build the bridge? 建这座桥花了多 少钱?

英语四种疑问句的用法归纳电子教案
英语四种疑问句的用法归纳 一、学习一般疑问句的五个要点 就全句提出问题，希望对方给予肯定或否定答复的问句，叫做一般疑问句。回答时要用Yes或No来开头，句末用问号，朗读时用升调。 (一)、一般疑问句的基本结构 1. 如果谓语中有情态动词、助动词或be，将这些词移到主语之前。如： Eg: Can you dance? 你会跳舞吗？ Will he go there tomorrow? 他明天去那里？ Are you a student? 你是学生吗？ 2. 如果谓语中没有情态动词、助动词或be，就在主语前加助动词do(does、did) ，原来 的动词都用原形。如： Eg: Do you like English? 你喜欢英语吗？ Does your brother like English? 你的兄弟喜欢英语吗？ Did you sleep well last night? 你昨晚睡得好吗？ 注：have做助动词时，将其移至主语前；作“有”解时也可以将其移至主语前；不是作“有”解的为行为动词时，其疑问式和其他行为动词一样要在主语前加do(does、 did) 。如： Eg: Has he gone to England? 他到英国去了？ Have you (=Do you have) a car? 你有汽车吗？ Do you have lunch at school? 你是在学校吃中饭的吗？ (二)、一般疑问句的简略回答 Eg: —Can you swim? 你会游泳吗？ —Yes, I can. (No, I can’t) 会。(不会) —Have you finished your work? 你工作做完了吗？ —Yes, I have. (No, I haven’t. ) 做完了。（还没有。） —Is this your pen? 这是你的钢笔吗？？ —Yes, it is. (No, it isn’t) 是的。（不是。） (三)、一般疑问句的否定形式 当说话人或是期待肯定的回答或是不期待对方的回答时用否定式。其结构，在口语里，总是把not与情态动词、助动词或be缩略成一个词；有时也将not放在主语后。如：Eg: Can’t you see the kite? 难道你看不到那个风筝？ Don’t you like playing football? 难道你不喜欢踢足球？ Aren’t you (=Are you not) a You Pioneer? 难道你不是少先队员？ (四)、注意否定疑问句的回答 英语的yes和no是对答语的肯定或否定，而不是对问句的肯定或否定，所以只要答语是肯定的，就用“Yes+肯定结构”，答语是否定的，就用“No+否定结构”。这与汉语的习惯不同。请比较： Eg: —Won’t he go to the hospital? 难道他不去医院了？ —Yes, he will . (No, he won’t. ) 不，他去。（是的，他不去。） —Can’t you speak English? 你难道不会讲英语吗？ —Yes, I can . (No, I can’t. ) 不，我会。（是的，我不会） 二、学习特殊疑问句的三个要点

英语疑问句用法大全
疑问句的定义 疑问句的主要交际功能是提出问题，询问情况。 分为一般疑问句、选择疑问句、特殊疑问句和反意疑问句。 一般疑问句 一般疑问句通常用来询问一件事情是否属实。答句通常是"yes或no"。所以一般疑问句有称作"是非问句"。 一. 由肯定的陈述句转化的一般疑问句。可以直接用“yes”或者“no”回答。 Do you speak English? 你讲英语吗？ Have you been living here? 你一直住在这儿吗？Can he swim? 他会游泳吗？ 二. 否定的一般疑问句。 Can't he drive? 他不是会开车吗？ Can he not drive? 他不会开车吗？
Isn't Kate a student? 凯特难道不是学生吗？ Is Kate not a student? 凯特不是学生吗？ Hasn't the rain stopped yet? 难道雨还没有停吗？Has the rain stopped yet? 雨还没停吗？ 三. 回答否定形式的一般疑问句的注意事项： Isn't she very intelligent? 她难道不是很聪明吗？ Yes, she is. 是的，她很聪明。 Is he not a student? 他不是学生吗？ Yes, he is. 不，他是学生。（错误的答语：No, he is.） 小窍门：在回答的时候，只要把它当成没有加以否定形式的普通一般疑问句一样看待。 选择疑问句 选择疑问句提出两个或两个以上可能的答案供对方 选择。这类疑问句由两部分组成：
（一般疑问句）供选择的第一个部分 + 供选择的另一个部分 + ？ Do you like to play football or basketball? 你喜欢踢足球还是打篮球？ Shall we walk, or shall we go by bus? 咱们步行去，还是乘公共汽车去？ Do you prefer apples, or pears, or plums, or cherries? 你是喜欢苹果、梨子、李子还是樱桃？ 注意：有的选择疑问句不能用"yes或no"回答。如：Are you male or female? 你是男性还是女性？ 这时是不可能用"yes或no"回答的。 但是，以下则例外。 Shall we walk, or shall we go by bus? 咱们步行去，还是乘公共汽车去？ 回答可能是： No, we shall go by taxi.
