Topic
Neither Pine nor Apple in Pineapple
Have you ever asked yourself why people often have trouble learning English I hadn't, until one day my five- year- old son asked me whether there was ham in a hamburger. There isn't. This made me realize that there's no egg in eggplant either. Neither is there pine nor apple in pineapple. This got me thinking how English can be a crazy language to learn.
老婆饼
鱼香肉丝
夫妻肺片
For example, in our free time we can sculpt a sculpture and paint a painting, but we take a photo. And when we are traveling we say that we are in the car or the taxi, but on the train or bus! While we're doing all this traveling, we can get seasick at sea, airsick in the air and carsick in a car, but we don't get homesick when we get back home. And speaking of home, why aren't homework and housework the same thing？
If “hard” is the opposite of “soft”， why are “hardly” and “softly” not an opposing pair If harmless actions are the opposite of harmful actions, why are shameless and shameful behaviors the same
When we look out of the window and see rain or snow, we can say “it's raining” or “it's snowing”. But when we see sunshine, we can't say “it's sunshining”．
Even the smallest words can be confusing. When you see the capitalized “WHO” in a medical report, do you read it as the “who” in “Who's that？” What about “IT” and “US”？
You also have to wonder at the unique madness of a language in which a house can burn up as it burns down, in which you fill in a form by filling it out, and in which an alarm is only heard once it goes off!
English was invented by people, not computers, and it reflects the creativity of the human race. That is why when the stars are out, they are visible, but when the lights are out, 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 Points
1．Have you ever asked yourself why people often have trouble 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 trouble(in) doing sth.意为“做某事有困难、费力”，其中doing 前面省略了in。其中trouble 为不可数名词，前面可用some，any，no，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 trouble/problem(in) doing sth.
have a hard time in doing sth.
there's difficulty/trouble with sth.
in doing sth.
I have difficulty/ trouble with English.
in learning English.
She had a hard time in finding his house.
There is difficulty/trouble with the text.
There is difficulty/trouble in finishing the task
on time.
①—Did you have trouble finding Ann's house
—Not really. She had given us clear directions and we were able to find it easily.
②For him, there is no difficulty _________(answer) such an easy question.
③I had a hard time ________(climb) up the horse while he was riding happily.
answering
climbing
[温馨提示]
在语法填空中，常将have trouble(in) doing sth.句式中的trouble/ difficulty提前作先行词，因此定语从句中have后常为 doing形式。试比较：
You can't imagine what great difficulty we have ever had finding the right person.
You can't imagine what great difficulty we have ever had found the right person.
Do you know the trouble I have ______ (learn) English
Do you know the trouble (that) I have (in) learning English
( √ )
(×)
2. This made me realize that there’s no egg in eggplant either.
“make+ 宾语+宾补”，宾语补足语通常由名词、形容词、省略to的不定式（短语）、过去分词来充当。“使……做某事”
It’ll make me happy if you accept it.
make+宾语+名词
And he made the whole factory a moving
production line.
make+宾语+形容词
News reports make people famous.
make+宾语+过去分词
I had to speak aloud to make myself heard
by all the students.
make+宾语+省略to的不定式
The teacher made the girl study six hours a day.
注意：
在被动语态中，此结构中被省略的不定式符号to要还原。
The girl was made to study six hours a day.
【语境应用】单句语法填空。
Paul doesn’t have to be made __________ (learn). He always works hard.
These photos made me _________(think) of my schooldays.
to learn

3．Neither is there pine nor 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 the students nor the teacher knows anything about it.
Either she or I am going there tomorrow.
Not only you but also he is going to join 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nor替换neither。
There is neither pine nor apple in pineapple.
Neither is there pine nor 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，nowhere，never，not，little，seldom，at no time，in no way，by no means，under no condition，not until，neither，nor等。
We should never give up.
