+than+B.”。如:Sam's sister is taller than mine. 萨姆的妹妹比我的妹妹高。
The result was more perfect than what we imagined. 结果比我们想象的更完美。
注意】为了避免重复,常用 the one(s), that, those等词来替代前面出现过的名词,其中 the
one替代可数名词单数,the ones或those替代可数名词复数,that替代不可数名词。如:
This room is bigger than the one next door. 这个房间比隔壁的那个要大。
(2)表示程度的副词,如 a lot, much, a bit, a little, even, far 等可以用来修饰形容词的比较
级。如:

3.形容词副词的最高级用法和句型(1)表示三者或三者以上的人或物进行比较时,用最高级形式。形容词最高级前通常加定冠词
the,句末常跟一个in / of / among短语来表示范围。如:

He is the strongest of the three boys. 他是3个男孩子中最强壮的一个。
(2)表示在三者或三者以上的人或物中进行选择时,用句型“Who / Which is+the+形容词最

Do you know the largest natural park in China? It is Sanjiangyuan National Park on the Qinghai-
Xizang Plateau (青藏高原). “Sanjiangyuan” means the source (源头) of China’s three great rivers: the
Yangtze River, Yellow River and Lancang River.The Yangtze River is the 1 (long) of the
three.
Sanjiangyuan is known as the Water Tower of China or even Asia. There are lots of rivers, lakes,
and wetlands. People living around all depend on its rich natural resources (资源). It is as 2
(important) as our life. However, with the global (全球的) warming and human’s activities, the place
was once in great danger. Life there was also much 3 (difficult) for both animals and humans
than that in other places. To stop things from getting 4 (bad), our government has taken many
ways, for example, building Sanjiangyuan National Park.
Now, people there are living in peace with animals and nature. Our country is trying its best to make
Sanjiangyuan National Park one of the 5 (famous) parks all over the world. I believe in the
future the park will be a window to show Chinese natural beauty to the outside.
