5.I was short ,so I couldn＇t ride my bike well. Now ,I go cyclingevery day.我以前个子小，自行车骑得不好，现在我天天骑自行车。

重难点精讲1.either 作副词，表示“也”时通常用于否定句中，而且要放在句尾。

He can＇t play football, and I can＇t either.There was no cars , and ___________________________________________.过去没有汽车，也没有电脑。

2.There was no library in my old school。

________________________________. 这是there be 结构的一般过去时态的否定句，表示“某地过去不存在某人或某物”。

there be 结构的一般过去时态的肯定句句式为“There was/ were +主语+地点”，其否定句是在was/ were 后加no或not，即：There + was/ were + no +主语+地点There +wasn＇t/ weren＇t +主语+地点There was no bridge over the river= There wasn＇t a bridge over the river.河上以前没有桥。

There were no flowers in the garden.= There weren＇t any flowers in the garden.花园里以前没有花。

“no +单数名词”相当于“not a /an +单数名词”.“ no +复数名词/ 不可数名词”相当于“not any +复数名词/ 不可数名词”. 。

所以上面例句中：no bridge= not a bridge no flowers= not any flowersThere was no boy over there{写出另外一句}__________________________________________________________________-There were no apples on the hill{写出另外一句}there be 的一般疑问句:Were /Was there +主语+地点？肯定回答：Yes, there was ./ Yes, there were.否定回答：No, there wasn't / No, there weren't.--Were there are many birds in the tree?--Yes, there were.--No ,there weren't.Was there any milk in the bottle?(作肯定回答) _______, _______ _______. Were there many fish in the river?(作否定回答) ________, ________ ___________. 注意：如果肯定句中有some，在否定句中和一般疑问句中要变为any。

There were some pencils on the desk.(肯定句)Were there any pencils on the desk?（否定句）There were some apples on the tree.(改为一般疑问句)_______________________________________________________________________________ 3.One day ,I am going to visit the moon._________________________________be going to 是用现在进行时表达将来的含义的一种结构，通常是指按计划，安排打算要做的事情，基本结构“主语+ be动词+ going to + 动词原形+其他“I am going to do my homework after dinner.We are going to make a kite.__________________________________________________________________他打算踢足球_____________________________________________________________________她打算去骑自行车。

be going to结构的各种句型总复习：肯定句：主语+ be动词+ going to+ 动词原形+其他He is going to read a book.否定句：主语+ be动词+ not + going to+ 动词原形+其他nShe isn＇t going to swim .一般疑问句：Be 动词+ 主语+ going to+ 动词原形+其他？肯定回答：Yes, 主语+be 否定回答: NO ,主语+ be not.--Is he going to take a trip?--Yes, he is. / No, he isn＇t.4.take 作动词，意为“花费{时间}”，常用于句型“It takes / took {+某人} +时间+to do sth.”.意为：做某事花费某人多长时间.It took me about two hours to made the snowman.大概花费我两小时去堆雪人。

打扫我的房间花费了我大约一个小时的时间。

（翻译成英语）_______________________________________________________________________________ 5.look up 为固定搭配，意思为“（在词典中或通过电脑）查阅”。

look up接名词作宾语时，该名词即可以置于look 与up 之间，也可以置于up之后；若接代词作宾语时，该代词只能置于look 与up之间。

You can look up the words in the dictionary.=You can look the words upin the dictionary.She looked it up in the book.6.There were no computers or internet in my time.__________________________. or在此作连词，用在否定句中表示“也不”，连接两个并列的单词，短语或句子。

I am not a teacher or a doctor.我不是老师也不是医生。

用在肯定句中表示“或者”I will stay at home or go to park.用在疑问句中表示选择，意思为“还是”。

Is your father a teacher or a doctor?用在祈使句中表示警告或忠告，意思为“否则”Hurry up, or you will be late.7.different.是形容词，意思为“不同的”,后接复数名词,反义词为same., 其后接单数名词，且在句中使用same.,时，常在它前面加上冠词the.We are in different school.We are at the same age.我们在不同的国家。

（翻译成英语）____________________________________________他们年纪一样大。

every与名词连用，意思为“每个，每一个”如：every week 每周，every month每个月，every class 每个班等。

I walk to school every day.She plays football every day.辨析every day 与everydayevery day意思为“每一天”，在句中作状语，相当于副词。

everyday作形容词，意思为“每日的，日常的”，在句中修饰名词作定语。
