Exploring EnglishPPT，第二部分內(nèi)容：要點(diǎn)規(guī)則詳析
英語中詞的構(gòu)成方法主要有三種：合成、派生和轉(zhuǎn)化。
一、合成
由兩個或更多的詞合成一個詞，有的用連字符“”連接，有的直接寫在一起，還有的由分開的兩個詞構(gòu)成。
1．合成名詞
2．合成形容詞
3．合成副詞
4.合成代詞
5．合成動詞
[點(diǎn)津] (1)合成詞的復(fù)數(shù)形式通常是把前面的主體名詞變復(fù)數(shù)。若沒有主體名詞，則在最后一個詞后面加復(fù)數(shù)形式。例如：fatherinlaw→fathersinlaw, grownup→grownups。
(2)由man和woman構(gòu)成的合成名詞變復(fù)數(shù)時，兩個名詞都要變成復(fù)數(shù)。例如：woman doctor→women doctors。
(3)由“名詞＋名詞”構(gòu)成的復(fù)合名詞，在變復(fù)數(shù)時，只變化中心名詞，而修飾名詞不變。例如：girlfriend→girlfriends。
[即時訓(xùn)練1]
(1)寫出下列單詞的漢語意思
①greenhouse_________
②sunset_________
③farreaching_________
④heartfelt_________
⑤hotfoot _________
⑥overcome _________
(2)將下列合成名詞變?yōu)閺?fù)數(shù)形式
①daughterinlaw→_________
②gobetween→ _________
③man teacher→ _________
④Englishman→_________
二、派生
派生法是由一個詞根加上前綴或后綴構(gòu)成另一個詞。
1．前綴
前綴一般只改變單詞的意思，不改變詞性。
2.后綴
后綴常會改變單詞的詞性，構(gòu)成意思相近的其他詞性；少數(shù)后綴還會改變詞義，變?yōu)榕c原來詞義相反的新詞。

Exploring EnglishPPT，第三部分內(nèi)容：語境即時活用
One day a little boy came into a fruit shop.He had five dollars and wanted to buy some apples.He said to the shopkeeper, “Give me apples for five dollars, please.” When the shopkeeper handed him the apples in a bag, the boy counted them and felt very surprised.Then he said, “Last Friday, my mother bought apples here for five dollars, too.Why did you give me fewer apples？”
“My boy, don't you know? The fewer apples you get, the less fruit you will have to carry.” said the shopkeeper.
“All right，” said the boy and he kept one dollar and gave the rest of the money to the shopkeeper.He was just going to leave the shop when he heard the words. “Come back! You must pay me five dollars.” “That's OK！” said the boy.“Don't you know? The fewer dollars you get, the less money you will have to count.”
點(diǎn)評：第一段第三句中的shopkeeper為“名詞＋名詞”結(jié)構(gòu)的合成詞；第四句中的handed為詞性轉(zhuǎn)化“名詞用作動詞”，surprised為帶有后綴ed的形容詞。

Exploring EnglishPPT，第四部分內(nèi)容：新知貫通
And the Americans find the British spelling“re”does not match its pronunciation, so they would rather spell re as er.
美國人覺得英國“re”的拼寫與發(fā)音不相匹配，所以他們寧愿把re拼作er。
★would rather寧愿；寧可
①I would rather stay at home reading than go swimming with my friends.
我寧可待在家里看書，也不愿意和朋友們一起去游泳。
②I'd rather (that) you hadn't told him about it that day.
我真希望你那天沒告訴他那件事。
[即時訓(xùn)練] 單句語法填空
①I would rather__________(mistake) than quarrel with him.
②George is going to talk about the geography of his country, but I'd rather he__________(focus) more on its culture.
③I would rather you________(go) there last night.

Exploring EnglishPPT，第五部分內(nèi)容：聽力強(qiáng)化
一、聽力技法微指導(dǎo)
做好聽前預(yù)測
聽前預(yù)測也是提高聽力測試成績的一種有效的方式。在正式開始聽錄音之前，應(yīng)先快速地瀏覽一遍題目，圈出題干與選項中的信息點(diǎn)，預(yù)測將會聽到的內(nèi)容，并明確聽錄音時的重心。首先，根據(jù)題干中的語言信息，預(yù)測對話或短文的語境、大意、人物身份等可能涉及的內(nèi)容。其次，對比分析選項的異同，特別注意各選項中重復(fù)出現(xiàn)的詞匯，明確下一步聽錄音時應(yīng)該關(guān)注的方向。
[典例] What will James do tomorrow?
A．Watch a TV program.
B．Give a talk.
C．Write a report.
[聽力原文]
W: James, you've been watching TV for the whole evening.What's on?
M: It's a science program on the origin of the universe.I'll give a presentation on it in my class tomorrow.
[分析] 首先根據(jù)題干中的關(guān)鍵詞“James, do, tomorrow”可預(yù)測這是一道考查動作行為的試題，聽時要密切關(guān)注James的講話內(nèi)容。再根據(jù)三個選項“看電視”“做演講”“寫報告”，可預(yù)測將會聽到的動作與其中之一有關(guān)，聽時可關(guān)注三個動詞“watch, give, write”。根據(jù)答句中James的回答“I'll give a presentation on it in my class tomorrow.”可知答案。give a presentation 與選項give a talk為同義轉(zhuǎn)換。故答案是B項。
