（一）课文详解1、get a dictionary.(P17)get此处为及物动词“获得、得到”，其后常跟名词作宾语。
get之后跟双宾语，常用短语：get sb. sth = get sth for sbeg: He got a letter from his friend yesterday.Get me a cup of tea. = Get a cup of tea for me.get常构成的短语有：get up起床get over克服、恢复get on / off上、下车get along / on with与..相处get back取回2、buy a newspaper(P17)1)buy及物动词，常用结构有：buy sb sth = buy sth for sbbuy sth from sbeg: He bought me this book = He bought this book for me.I bought this watch from a friend for $10.2)buy是非延续性动词，不能与how long及for引导的表示一段时间的状语连用。
表示“某物买了多长时间”用have代替buyeg: I have had the bike for two months.How long have you had your dictionary3)buy的反义词是sell，常用短语有：sell sth to sb = sell sb stheg: I sold my car to my younger brother. = I sold my younger brother my car.3、Excuse me, could you please tell me how to get to the bookstore?(P17)1)Could you please….?表示委婉的请求，后接动词原形。
类似的表示请求的句型还有：Would / Will you please do sth?Would you like to do sth?2)could为情态动词，也是can的过去式，在表达请求时，could与can没有时态上的差别，只是could的语气比较委婉和客气3)hot to get to the bookstore是“疑问词+动词不定式”结构。
疑问词who, which, when, where,how, what等与动词不定式连用，常用语tell, show, know, teach, learn, explain等后作宾语，“疑问词+动词不定式”结构所表示的动作通常是未发生的，所以在转换成宾语从句时，通常要加情态动词或用将来时态。
eg: He didn’t know what to say. = He didn’t know what he should say.4、Sure,just go along Main Street until you pass Center Street.(P17)1)go along“沿着….向前走”，与go down / up同义，常用于指路。
常用的句子还有：walk along / down this road / streetturn left / right at the +序数词+ crossing / turningyou can take the No. +数字+ bus and get off at…….It’s next to / across fromwalk on and turn left / right2)until与till的用法区别①until可以放在句首，till不能。
till多用于口语中。
两个词都可以用作介词，也可以用作连词。
作介词时，后接词或短语，在句子中作状语；作连词时引导时间状语从句。
②until / till用于肯定句中，句子或主句的谓语动词必须是延续性动词，表示这一动作或状态一直延续到until / till所表示的时间为止。
这样的动词有live, wait, last, work等eg: He watched TV until / till midnight last night.I waited for him until / till he came back.③until / till用于否定句中，其句型为：not…..until / till“直到…..才….”或“在…之前不”，通常与非延续性动词连用，强调句子或主句所表示的状态或动作从until/till所表示的时间才发生，句子或主句必须是否定句。
表示非延续性的动词有come,go,leave,meet,realize,understand, reach, get, arrive等eg: He didn’t go home until / till ten o’clock.I hadn’t realize the thing was so serious until / till she told me about it. = Until she told meabout it, I hadn’t realized the thing was so ser ious.5、go to the thinrd floor(P18)the first floorthe second floorthe third floor (美式英语)the ground floorthe first floorthe second floor(英式英语)6、turn left(P18)1)turn left = turn to the left.此处turn是不及物动词，意为“转向”①turn的其他用法作不及物动词，“转动，转身”eg: Ricky turned an d walked away.作及物动词，“转动，旋转”eg: He turned the key in the lock.作连系动词，“变为，成为”eg: When spring comes, the trees turn green.作名词，“轮流”eg: It’s your turn to read now.②与turn有关的短语：turn right = turn to the rightturn on / offturn down / up2)leftadv.“向左，在左边”n“左边”adj“左边的”v.“离开”（leave的过去式和过去分词）eg: The little boy is sitting on my left.I left my homework at home.7、go past the bookstore(P18)go past“经过”相当于pass，其中past为介词，“从…旁边过去”eg: The train went past us without stopping at the station.past“从…旁边经过”，表示时间上的“超过”或空间上的“经过”eg:The man is walking past a shop.over“从…上方跨越而过”，表示动作发生在物体的上方eg: There is a bridge over the river.across“横穿、越过”，表示动作是在某一个物体的表示进行的，强调从一端到另一端eg:The little boy is walking across the road.through“穿过，越过”，表示动作是在某一空间内进行的，强调从内部穿过eg: He can go through the forest by himself.8、Nine thirty, so you don’t need to rush!(P18)rush此处用作不及物动词，“仓促、急促”，也可用作及物动词。
常用短语：rush to do stheg: He sprang up and rushed to the door.She’s always rushing to finish first.rush用作名词时“匆忙、高峰”，常用短语：in a rushrush hour9、I suggest Water City Restaurant in Water World.(P19)suggest及物动词“建议、提议”名词形式：suggestion.其用法为：suggest sth“建议某事”eg: He suggested a walk.suggest doing sth“建议做某事”eg: She suggested going there by bike.suggest + that引导的宾语从句，这时宾语从句要用虚拟语气，谓语动词用（should）+动词原形eg: He suggested that we should do it at once.10、On their way to Water City Restaurant, Alice and He Wei pass by Uncle Bob’s.(P19)1)on one’s way to….“在某人去…的路上”eg: Yesterday I met a friend of mine on my way to school.常见的与way相关的短语有：bytheway顺便说一下inaway在某种程度上intheway挡路，妨碍in this way通过这种方法lose one’s way迷路2）Uncle Bob’s = Uncle Bob’s restanrant,当名词所有格限定的是表示住宅、诊所、商店等名词时，该名词通常可以省略。
eg: They are at the doctor’s(office).He is going to his aunt’s(house) this Sunday.11、It’s always busy, so come a little earlier to get a table.(P19)a little earlier“早一点儿”,其中a little在句中修饰比较级earlier.在形容词比较级前常用much,a little, a bit, even, still等来修饰，表示程度进一步加深。
eg: I have much more homework than him.He is even busier today.12、Sally needs to mail a letter.(P20)mail此处用作及物动词，“邮寄”，相当于动词post，还可意为“发店子邮件”。
