請問decrease後面的介係詞...

想請問各位大大,字典上decrease後面是+in/to

為何這句話

The population of district decreased "by" 10% last year.

是使用介係詞by呢??

><搞不懂

已更新項目:

hi louis大大

是我少漏了一個the~"~

呵呵

我是用dr.eye的字典

vi. (不及物動詞 intransitive verb)

1.

減;減少,減小[(+in/to)]

Car sales are decreasing.

汽車銷售量下跌。

~"~是這樣寫的

所以覺得有些奇怪

2 個已更新項目:

所以是因為by這個介係詞有表變化的意思嘛@@?

謝謝^^

    The population of this district decreased by 10% this year.(在district前面,你的句子是否漏了字?)

    這句的decreased是當不及物動詞。後面的by是用來表示變化或差別有多大的。和一般用來表示被動的狀況不同。類似的句子有 House prices rose by an average 23% last year. Owen broke the world record by 2.4 seconds.

    decrease其它用法如下:

    The new system decreases the risk to public health.這句的decreases是及物動詞。

    There has been a decrease in the birth rate in the indsutrialized world.這句的decrease是名詞。

    decrease但當動詞用時,字典裡好像沒有接介系詞in及to的用法。你是否看錯了?

    2009-05-02 21:25:23 補充:

    你給的句子中by 10%是一個介系詞片語,當修飾decrease的修飾語,屬副詞性質。

    你所說的decrease後面要用in/to,應該分開來討論,因為decrease後面該用in或to,不是由decrease來決定,而是由後面當in及to受詞的名詞來決定。後面是一個介系詞片語,是decrease的修飾語。

    字典上decrease沒有和任何介系詞形成動詞片語的例子。
