本 講主要內(nèi)容
（一）本語法知識(shí)講解：形容詞比較級(jí)和最高級(jí)
（二）后寫作練習(xí)題答案

知識(shí)與歸納
（一）本語法知識(shí)講解
形容詞比較級(jí)和最高級(jí)
as + 形容詞或副詞原級(jí) + as
1）在否定句或疑問句中可用so… as.
He cannot run so/as fast as you.
2）當(dāng)as… as 中間有名詞時(shí)采用以下格式。
as +形容詞+ a +單數(shù)名詞
as + many/ much +名詞
This is as good an example as the other is.
I can carry as much paper as you can
3）用表示倍數(shù)的詞或其他程度副詞做修飾語時(shí)，放在as的前面。
This room is twice as big as that one.
Your room is the same size as mine.
4）倍數(shù)+ as + adj. + as　<=> 倍數(shù)+ the + n + of
Th is bridge is three times as long as that one.
This bridge is three times the length of that one.
Your room is twice as large as mine.
Your room is twice the size of mine.
比較級(jí)形容詞或副詞 + than
You are taller than I.
They lights in your room are as bright as those in mine.
注意：
1）要避免重復(fù)使用比較級(jí)。
（錯(cuò)）He is more cleverer than his brother.
（對(duì)）He is more clever than his brother.
（對(duì)）He is clever than his brother.
2）要避免將主語含在比較對(duì)象中。
（錯(cuò)）China is larger that any country in Asia.
（對(duì)）China is larger than any other countries in Asia.
3）要注意對(duì)應(yīng)句型，遵循前后一致的原則。
The population of Shanghai is larger than th at of Beijing.
It is easier to make a plan than to carry it out.
4）要注意冠詞的使用，后有名詞的時(shí)候，前面才有可能有名詞。
比較：
Wh ich is large，Canada or Australia？
Which is the larger country，Canada or Australia？
She is taller than her two sisters.
She is the taller of the two sisters.
可修飾比較級(jí)的詞
1）a bit，a little，rather，much，far，by far，many，a lot，lots，a great deal，any，still，even等
2）還可以用表示倍數(shù)的詞或度量名詞作修飾語。
3）以上詞（除by far）外，必須置于比較級(jí)形容詞或副詞的前面。
man y，old 和far
1）如果后接名詞時(shí)，much more +不可數(shù)名詞
many more +可數(shù)名詞復(fù)數(shù)
2）old 有兩種比較級(jí)和最高級(jí)形式：older/oldest 和elder/eldest. elder，eldest 只用于兄弟姐妹的長(zhǎng)幼關(guān)系。
y elder brother is an engineer.
ary is the eldest of the three sisters.
3）far 有兩種比較級(jí)，farther，further. 在英語中兩者都可指距離。
在美語中，farther 表示距離，furthe r表示進(jìn)一步。
I have nothing further to say.
the + 最高級(jí) + 比較范圍
1）The Sahara is the biggest desert in the world.
形容詞最高級(jí)前通常必須用定冠詞 the，副詞最高級(jí)前可不用。
形容詞most前面沒有 the，不表示最高級(jí)的含義，只表示“非�！�。
It is a most important problem.
=It is a very important problem.
注意：使用最高級(jí)要注意將主語包括在比較范圍內(nèi)。
（錯(cuò)）Tom is the tallest of his three brothers.
（對(duì)）Tom is the tallest of the three brothers.
2）下列詞可修飾最高級(jí)，by far，far，much，mostly，almost
This hat is nearly / almost the biggest.
注意：
a. very可修飾最高級(jí)，但位置與much不同。
This is the very best.
This is much the best.
b. 序數(shù)詞通常只修飾最高級(jí)。
Af rica is the second largest continent.
3）句型轉(zhuǎn)換：
ike is the most intelligent in his class.
ike is more intelligent than any other students in his class.
4）“否定詞語+比較級(jí)”，“否定詞語+ so… as”結(jié)構(gòu)表示最高級(jí)含義。
Nothing is so easy as this.
=Nothing is easier than this.
=This is the easiest thing.

P29 A
Dear Gran
Yesterday, um and Dad gave us two radio-controlled cars for our birthday. They are great! Nigel’s car is a ‘Lightning’. It is (1) faster than mine, which is rather slo y car is a ‘Hi-Climb’, and it is (2) better at climbing over things than the ‘Lightning’. The ‘Lightning’ is (3) longer and (4) lower th an the ‘Hi-Climb’. The ‘Hi-Climb’ weights 210 g and so it is (5) heavier than the ‘Lightning’, and this means that the battery use is heavier (6) than the ‘Lightning’, too.
The ‘Lightning’ is (7) lighter, with a weight of just 150 g. This means that is can go (8) farther on one set of batteries. Sometimes we put toy people in the cars. The ‘Hi-Climb’ can hold (9) more passengers, as it has 4 seats. The ‘Lightning’ is good on a flat surface, but it is (10) worse than the ‘Hi-Climb’ on rough ground, because it cannot climb over things.
Love
Robin

Dear Peter
Thanks for your letter. In reply to the question at the end, my parents have just bought a new flat! They looked at one in Peak Villa and one in Seaside Court. They chose Peak Villa. The flat there is bigger than the flat in Seaside Court, but it has fewer rooms. It is also more modern, and its price is higher. It is nearer to the school, but it is farther from the market. Finally, the view from peak Villa is better than the view from Seaside Court. I’ll send you a photo in my next letter.
Best wishes
Robin
