The establishment of national parks makes many of these beautiful places protected areas for the public to visit and enjoy, such as Banff and Jasper National Parks.
国家公园的建立使许多这些美丽的地方成为公众参观和欣赏的保护区,如班夫国家公园和贾斯珀国家公园。
句式剖析:
在本句中,many of these beautiful places 是谓语动词makes的宾语,而protected areas是宾语补足语。这是动词make的常见用法:make+宾语+宾语补足语。
考点提炼:“make+宾语+宾语补足语”结构
“make+宾语+宾语补足语”结构有以下几种形式:
(1)make+名词/代词+不带to的动词不定式。当该结构用于被动语态时,动词不定式符号to不能省略。
The shocking news __________________.
这个令人震惊的消息使他的心跳加快了。
John ___________________________ as a punishment.
约翰被迫打扫房子,以此作为惩罚。
(2)make+名词/代词+过去分词。构成过去分词的动词与宾语(名词/代词)之间是逻辑上的动宾关系,且分词动作已完成。值得注意的是,不能用现在分词做宾语补足语。
His actions __________________.
他的行为使他大受尊敬。
made his heart beat faster
was made to clean the house
made him greatly respected
(3)make+名词/代词+形容词。该结构表示“使某人或某物变得······”。
We must _________________________.
我们必须把房间打扫干净。
(4)make+名词/代词+名词。该结构表示“使某人或某物成为······”。如果宾语补足语是表示独一无二的职位或头衔的名词时,则其前不用冠词。
___________________________________.化敌为友。
We made Tom captain, for he was more experienced.
(5)当宾语是动词不定式或从句时,多用it做形式宾
语,把真正的宾语后置,即构成“make it+宾语补足语(形容词/名词)(+for sb.)+真正的宾语”结构。
The heavy rain ___________________________________.
大雨使我们无法出去。
I ___________________________ every day.
我养成了每天写日记的习惯。
make the room clean
made it impossible for us to go out
_make it a rule to keep a diary
Make your enemy your friend

句式剖析:
one out of five people 用到了分数的表达方式之一,在该句中做主语。
考点提炼:分数的表达方式及其用法
(1)分数的表达方式有两种:
