2020版一轮复习英语新课改·人教版学案：专题三形容词与副词

专题三形容词与副词

1．用法

(1)表示双方在程度、性质、特征等某方面相等时，用“as＋形容词/副词的原级＋as” “as＋形容词＋a(n)＋单数名词＋as”“as＋many/much＋复数名词/不可数名词＋as”的结构；

Henry is a worker as good as Peter (is)．＝Henry is as good a worker as Peter (is)．

亨利和彼得一样都是好工人。

It is generally believed that teaching is as much an art as it is a science.

人们普遍认为，教学是一门科学，同时也是一门艺术。

(2)表示双方不相等时，用“not so/as＋形容词/副词的原级＋as”的结构；

Henry does not have so/as many books as I have.

亨利的书不如我的多。

[名师指津]　as＋形容词＋as＋数量词＝数量词＋形容词

The building is as tall as 100 meters.＝The building is 100 meters tall.

这幢楼有100米高。

2．as ...as结构前可用almost, exactly, half, just, nearly, quite等修饰，表示程度。

Let's walk. It's just as quick as taking the bus.

咱们走路去吧，这和坐公共汽车去一样快。

1．比较级与最高级的构成

(1)规则变化：

[名师指津]　有些形容词和副词没有程度可分或形容词和副词本身就是某种程度，因此没有比较级和最高级。如right, wrong, excellent, extreme, perfect, possible, empty, greatly, very等。

(2)不规则变化：

[名师指津]　①farther和farthest分别指时间或空间上“较远”“最远”。②elder不能与than连用，只能用作定语修饰名词，且仅用于同辈之间的排行。elder sister姐姐；elder brother哥哥。

2．比较级的用法

(1)比较级的常见结构

①表示一方不及另一方时，用“less＋原级＋than”结构。

This computer is less expensive than mine.

这部电脑没有我的贵。

②表示一方程度随另一方程度平行变化时，用“the＋比较级．.., the＋比较级．..”，意为“越……就越……”。

The busier he is, the happier he feels.

他越忙就越感到高兴。

③不与其他事物相比较，表示本身程度的改变时，用“比较级＋and＋比较级”结构，意为“越来越……”。

Our school is becoming more and more beautiful.

我们学校变得越来越漂亮了。

④表示“和……一样不……”时，用“no＋比较级＋than”结构。

You are no taller than I．你和我一样矮。

⑤“the＋比较级＋of the two＋名词”表示“两个中较……的那个”。

The taller of the two boys is my brother.

那两个男孩中较高的那个是我的哥哥。

(2)比较级形式表示最高级意义的表达方式

I have never spent a more worrying day.

这是我度过的最令人焦虑的一天。

I can't agree more.我完全同意。

He is better at English than anything else.

他最擅长英语。

Every morning he arrives earlier than any other student in the class.

＝Every morning he arrives earlier than all the other students in the class.

＝Every morning he arrives earlier than anyone else in the class.

＝Every morning he arrives earlier than any of the other students in the class.

＝Every morning he arrives earlier than the rest of students in the class.

每天早上他都是班里来得最早的。

(3)修饰比较级的常用词和短语有rather, much, still, even, far, a lot, a little, a great deal, (by) far, a bit等。

The students study even harder than before.

学生们比以前学习更努力了。

3．最高级的用法

(1)形容词最高级(＋名词)＋表示范围的状语

She is the most active student in our class.

她是我们班最活跃的学生。

(2)one of＋形容词最高级＋名词复数

Shanghai is one of the biggest cities in our country.

＝Shanghai is among the biggest cities in our country.

上海是我国最大的城市之一。

(3)序数词＋形容词最高级＋名词

Africa is the second largest continent in the world.

非洲是世界上第二大洲。

(4)常用的最高级的修饰语有by far, nearly, almost, by no means, not really以及序数词等。

I'd like to buy the second most expensive camera.

我想买便宜一点的照相机。

[名师指津]　by far通常用来修饰最高级，但也可修饰比较级，修饰比较级时，一般放在比较级后面，若在前面，应在两者之间加the。

The book is better by far than that one.

这本书要比那本书好得多。

He is by far the taller of the two brothers.

他是两兄弟中较高的那一个。

Pandas eat almost nothing __4__ bamboo shoots and leaves. __5__ (occasion) they eat other plants, fish, or small animals, but bamboo accounts __6__ 99 percent of their diets. Pandas eat fast; they eat a lot, and they spend about 12 hours a day __7__ (do) it. The reason is that they digest only about a __8__ (five) of what they eat. Overall, bamboo is not very nutritious. To stay healthy, they have to eat a lot — up to 15 percent of their body weight in 12 hours — so they eat fast.

Pandas' molars (臼齿) are very broad and flat. The shape of these teeth helps the animals crush the bamboo shoots, leaves, and stems they eat. __9__ (get) the bamboo to their mouths, they hold the stems with their front claws, which have enlarged wrist bones that act as thumbs for grasping things. A panda should have at least two bamboo species where it lives, or it will starve. Pandas are shy; they never leave areas __10__ they live. This restricts pandas to very limited areas.
