4 . HOW TO PLANT A TREE 如何種樹
［釋疑］ ( 1 ) 英語中用作標題的文字，一般常用大寫。

to keep it straight 是動詞不定工，在句中作狀語，表示捆樹的目的。straight 是賓語 it 意義上的補充和延伸，所以叫做賓語補足語。又如：

( 2 ) 該句為一般過去時被動語態(tài)。
11 . In 1850 , about a third was covered by forests . 1850年，大約三分這一 ( 的美國國土 ) 被森林覆蓋。A third 即為 one third 或 1/3。
［釋疑］英語中分數(shù)的文字表達，分子用基數(shù)詞，分母用序數(shù)詞，先讀分子，后讀分母。當分子大于1時，分母用相應(yīng)的復(fù)數(shù)。例如：2 / 3 讀作 two thirds . 5 / 7 讀作 five sevenths .

單元語法發(fā)散思維
※ 含有情態(tài)動詞的被動態(tài)
含有情態(tài)動詞的被動結(jié)構(gòu)是：情態(tài)動詞 + be + 及物動詞的過去分詞。如：
We must find out the truth . → The truth must be found out .
These machine parts may be needed in our work .
Should an article be used here ?
These stairs are very dangerous . They should be repaired .
This lesson must be gone over again .
※ 被動語態(tài)與系表結(jié)構(gòu)的區(qū)別
動詞 be + 過去分詞這個結(jié)構(gòu)并不定都是被動語態(tài)結(jié)構(gòu)，有時它可能是 be + 過去分詞 ( 作表語 ) 的系表結(jié)構(gòu)。因此：
be + 過去分詞 ( 被動語態(tài) ) 與 be + 過去分詞 ( 作表語 ) 這兩種結(jié)構(gòu)的主要差別是：
①被動結(jié)構(gòu)表示一個動作，帶表語的結(jié)構(gòu)表示主語的特點或所處的狀態(tài)。如：
The library is now closed . ( 系表結(jié)構(gòu) )
It is usually closed at 6 . ( 被動結(jié)構(gòu) )
②被動結(jié)構(gòu)后面可帶 by + 實施動作者，而系表結(jié)構(gòu)一般沒有。如：
The glass is broken . ( 系表結(jié)構(gòu) )
It was broken by my sister . ( 被動結(jié)構(gòu) )
③“系表結(jié)構(gòu)”中的過去分詞可以被 well , very 等副詞修飾，而“被動結(jié)構(gòu)”中的
過去分詞則一般不能如此。如：
The book is well written . ( 系表結(jié)構(gòu) )
The book is written by Li Ming . ( 被動結(jié)構(gòu) )
④被動結(jié)構(gòu)可以用于許多時態(tài)之是，而系表結(jié)構(gòu)只用于一般現(xiàn)在時和一般過去時這兩種時態(tài)。如：
The work is being done . ( 被動語態(tài) )
The work is done . ( 系表結(jié)構(gòu) )
⑤系表結(jié)構(gòu)有主動意義，而被動結(jié)構(gòu)只有被動意義。被動結(jié)構(gòu)的句子往往有表示動作的時間、地點、方式、目的等狀語，而系表結(jié)構(gòu)一般沒有這樣的狀語。如：
The photo was taken last month . ( 被動語態(tài) )
The photo was well taken . ( 系表結(jié)構(gòu) )

Making Omelettes
Omelettes are made from eggs and a few other things . They are quite easy to make .
First , crack the eggs and put them into a bowl . Use two or three eggs for each person . Mix the eggs well with a fork or with chopsticks . Mix the eggs until the mixture is all the same color — all right yellow .
Second , take the things , or ingredients , that you want to add to the omelette . For example , you can add cheese , or ham , or vegetables . Cat the ingredients into small pieces .
Third , put a little bit of butter or margarine into the bottom of a frying pan . Light the stove and melt the butter . You need butter or margarine so that the eggs won\'t stick to the pan .
Fourth , pour the eggs into the frying pan . Then put the other ingredients on top of the eggs .
After a couple minutes , turn the eggs over . Use a fork , or a spatula , or an egg-turner . When both sides of the eggs are cooked , remove the omelette from the pan . It is ready to eat .
