    The authr's pinin
    Neither Pine nr Apple in Pineapple Have yu ever asked yurself why peple ften have truble learning English? I hadn't, until ne day my five-­year-­ld sn asked me whether there was ham in a hamburger. There isn't. This made me realize that there's n egg in eggplant either. Neither is there pine nr apple in pineapple. This gt me thinking hw English can be a crazy language t learn.
    Fr example, in ur free time we can sculpt a sculpture and paint a painting, but we take a pht. And when we are traveling we say that we are in the car r the taxi, but n the train r bus! While we're ding all this traveling, we can get seasick at sea, airsick in the air and carsick in a car, but we dn't get hmesick when we get back hme. And speaking f hme, why aren't hmewrk and husewrk the same thing?
    If “hard” is the ppsite f “sft”, why are “hardly” and “sftly” nt an ppsing pair? If harmless actins are the ppsite f harmful actins, why are shameless and shameful behavirs the same? When we lk ut f the windw and see rain r snw, we can say “it's raining” r “it's snwing”. But when we see sunshine, we can't say “it's sunshining”. Even the smallest wrds can be cnfusing. When yu see the capitalized “WHO” in a medical reprt, d yu read it as the “wh” in “Wh's that?” What abut “IT” and “US”?
    Yu als have t wnder at the unique madness f a language in which a huse can burn up as it burns dwn, in which yu fill in a frm by filling it ut, and in which an alarm is nly heard nce it ges ff! English was invented by peple, nt cmputers, and it reflects the creativity f the human race. That is why when the stars are ut, they are visible, but when the lights are ut, they are invisible. And that is why when I wind up my watch, it starts, but when I wind up this passage, it ends.

    Language Pints
    1.Have yu ever asked yurself why peple ften have truble learning English?(P14)你有没有问过自己为什么人们在学习英语时经常遇到困难? 句中have truble(in) ding sth.意为“做某事有困难、费力”,其中ding 前面省略了in。其中truble 为不可数名词,前面可用sme,any,n,little等词来修饰。
    [归纳拓展]表示“做某事有困难”的常见结构:have difficulty with sth.have truble/prblem(in) ding sth.have a hard time in ding sth.there's difficulty/truble with sth. in ding sth.
    I have difficulty/ truble with English. in learning English.She had a hard time in finding his huse. There is difficulty/truble with the text.There is difficulty/truble in finishing the task n time.
    ①—Did yu have truble finding Ann's huse? —Nt really. She had given us clear directins and we were able t find it easily.②Fr him, there is n difficulty _________(answer) such an easy questin.③I had a hard time ________(climb) up the hrse while he was riding happily.
    [温馨提示]在语法填空中,常将have truble(in) ding sth.句式中的truble/ difficulty提前作先行词,因此定语从句中have后常为 ding形式。试比较:Yu can't imagine what great difficulty we have ever had finding the right persn. Yu can't imagine what great difficulty we have ever had fund the right persn.
    D yu knw the truble I have ______ (learn) English?
    D yu knw the truble (that) I have (in) learning English?
    2. This made me realize that there’s n egg in eggplant either. “make+ 宾语+宾补”,宾语补足语通常由名词、形容词、省略t的不定式(短语)、过去分词来充当。“使……做某事” It’ll make me happy if yu accept it.
    make+宾语+名词 And he made the whle factry a mving prductin line.make+宾语+形容词News reprts make peple famus.make+宾语+过去分词I had t speak alud t make myself heard by all the students.
    make+宾语+省略t的不定式The teacher made the girl study six hurs a day.注意:在被动语态中,此结构中被省略的不定式符号t要还原。The girl was made t study six hurs a day.
    【语境应用】单句语法填空。Paul desn’t have t be made __________ (learn). He always wrks hard.These phts made me _________(think) f my schldays.
    3.Neither is there pine nr apple in pineapple. pineapple(菠萝)里既没有pine(松树)也没有apple(苹果)。
    (1)“就近一致”原则neither…nr…连接两个名词或代词作主语时,谓语动词的数遵循“就近原则”,有同样用法的还有either…r…(或者……或者……),nt nly…but als…(不但……而且……),nt…but(不是……而是……)等。
    Neither the students nr the teacher knws anything abut it.Either she r I am ging there tmrrw.Nt nly yu but als he is ging t jin the club.
    (2) 否定副词放句首,主句构成部分倒装。neither置于句首的部分倒装句式语序为:neither+系动词be/助动词/情态动词+主语+动词原形(不含系动词be) +其他成分。可用nr替换neither。There is neither pine nr apple in pineapple.Neither is there pine nr apple in pineapple. [归纳拓展]以否定副词位于句首时,主句要部分倒装。常见的表示否定意义的副词(短语)有: hardly,rarely,scarcely,nwhere,never,nt,little,seldm,at n time,in n way,by n means,under n cnditin,nt until,neither,nr等。
    We shuld never give up.Never shuld we give up.He seldm came t visit me when I was in England.Seldm did he cme t visit me when I was in England. 
    ①If he desn't g t the park tmrrw, neither/ nr will I.②Nr ______________________ where we shuld g next. 我也不知道我们下一步去哪里。③Never ________________________ s wnderful as that. 以前我从未看见那样精彩的东西。④Little ____________________ the man making speech. 我们对这个演讲的人几乎一无所知。

    [归纳拓展](1)This/That/It is because...这是/那是因为…… (because引导表语从句,表示原因) This/That/It is why...这是/那是…的原因 (why引导表语从句,表示结果) I was late. This is because I gt up late.I gt up late. This is why I was late.(2) The reasn why... is that...……的原因是……(why引导定语从句,that引导表语从句,表示原因)The reasn why I was late is that I gt up late.
