1.形容詞及其用法
1)表語形容詞只能作表語，這類形容詞沒有級的變化，也不可用程度副詞修飾。大多數以a開頭的形容詞都屬於這一類。例如：afraid，afraid，alike，alive，alone，asleep，awake等。
2)形容詞作定語修飾名詞時，要放在名詞的前邊。但是如果形容詞修飾以-thing為字尾的詞語時，要放在這些詞之後。例如：something nice.
2.以-ly結尾的形容詞
大部分形容詞加-ly可構成副詞。但friendly，deadly，lovely，lonely，likely，lively，ugly，brotherly，仍為形容詞。
3.用形容詞表示類別和整體
1)某些形容詞加上定冠詞可以泛指一類人，與謂語動詞的複數連線，如the dead，the living，the rich，the poor，the blind，the hungry等。例如：
The poor are losing hope. 窮人行將失去希望。
2)有關國家和民族的形容詞加上定冠詞指這個民族的整體，與動詞的複數連用，如the British，the English，the French，the Chinese等。例如：
The English have wonderful sense of humor. 英國人頗有幽默感。
4.形容詞與副詞的比較級
常見的雙音節或多音節詞，在前面加more，most來構成比較級和最高階important/ easily more important/ more easily most important/ most easily
+ 形容詞或副詞原級+ as
1)在否定句或疑問句中可用so… as.例如：
He cannot run so/as fast as you. 他沒你跑得快。
2)用表示倍數的詞或其他程度副詞做修飾語時，放在as的前面。例如：
This room is twice as big as that one. 這房間的面積是那間的兩倍。
Your room is the same size as mine. 你的房間和我的一樣大。
3)倍數+ as + adj. + as 倍數+ the … + of.例如：
This bridge is three times as long as that one. 這座橋的長度是那座的.三倍。
This bridge is three times the length of that one.
Your room is twice as large as mine. 你的房間是我的兩倍大。
Your room is twice the size of mine.
6.可修飾比較級的詞常用的有a little，rather，much，far，many，等Nanjing is a little/rather/much/far/ hotter than Shanghai.如果後接名詞時，much more +不可數名詞，many more +可數名詞複數。
I have many more books than Tom.
There is much more water in the south than in the north.
7. the + 最高階+ 比較範圍
1)形容詞最高階前通常必須用定冠詞the，副詞最高階前可不用。例如：
The Sahara is the biggest desert in the world. 撒哈拉沙漠是世界上最大的沙漠。
形容詞most前面沒有the，不表示最高階的含義，只表示“非常”。例如：
It is a most important problem. =It is a very important problem. 這是個很重要的問題。
2)by far一般修飾最高階，
This question is by far the most difficult in this exercise. 這道題是這個練習裡最難的。
注意：最高階的意義有時可以用比較級表示出來。例如：
Mike is the most intelligent in his class. 馬克是班上最聰明的。
Mike is more intelligent than any other students in his class. 馬克是班上最聰明的。
8. 和more有關的片語
the more…the more… 越……越……。例如：
The harder you work，the greater progress you'll make. 越努力，進步越大。
【拓展閱讀】be going to / will
用於條件句時，be going to 表將來，will 表意願
例句：
If you are going to make a journey, you'd better get ready for it as soon as possible.
Now if you will take off your clothes, we will fit the new clothes on you in front of the mirror.
一般現在時表將來
1)下列動詞：come, go, arrive, leave, start, begin, return的一般現在時表將來。這主要用來表示在時間上已確定或安排好的事情。
The train leaves at six tomorrow morning.
When does the bus star? It stars in ten minutes.
2)倒裝句，表示動作正在進行，如：
Here comes the bus. = The bus is coming.
There goes the bell. = The bell is ringing.
3)在時間或條件句中。
When Bill comes (不是will come), ask him to wait for me.
I'll write to you as soon as I arrive there.
4)在動詞hope, take care that, make sure that等後。
I hope they have a nice time next week.
Make sure that the windows are closed before you leave the room.
