also用作副詞，表示也、而且、同樣地；表示兩件事的性質相近或兩件事情發(fā)生的時間相同，也可表示剛說過的話也適用于另一個人或物。

1.also是較正式的用詞，多用于書面語，基本意思是“也”“還”,表示兩件事的性質相近或兩件事情發(fā)生的時間相同，也可表示剛說過的話也適用于另一個人或物。在句中起補充追加的作用。

2.also主要用于肯定句和疑問句。在書面語中,also偶可用在no,nothing或其他帶有否定意義的詞之前，而在否定詞之后則不能用also,而要用either(但not also可用于反詰疑問句或修辭疑問句，偶爾也用于陳述句)。

3.also多位于實義動詞之前，非實義動詞或第一個非實義動詞之后,有時可放在整個謂語動詞之前,間或用于句末。偶爾為了加強語氣, also還可放在句首。also在句中位置不同常會影響句子的意思。

4.not only ... but also 不但 ... 而且...

（1） not only … but also 應連接兩個相對稱的并列成分。

I not only play tennis but also practise shooting. （連接兩個謂語動詞）

He plays not only the piano but also the violin. （連接兩個賓語）

（2）not only … but also 連接兩個分句，并且 not only 位于句首時，第一個分句中的主語和謂語要部分倒裝。例如：

Not only is this young man clever but also he is hardworking.

這個年輕人不僅聰明，而且勤奮。

（3）not only … but also 不能用在否定句中。

（4）not only … but also 連接兩個主語時，謂語動詞要和與其最近的主語保持人稱和數的一致。例如：

（5）not only … but also 中的 not only 不能分開使用，但 but also 卻可以分開使用。例如：

The area was not only hit by an unexpected heavy rain， but some bridges were also washedaway.

（6）not only … but also 連接兩個并列成分時，可以省略 but 或 also ，也可以把 but also 都省略掉。例如：

I not only heard it but （also） saw it.

He was not only compelled to stay at home， （but） also forbidden to see his friend.

She not only finished the task ahead of time， （but also） she came to help us.

（7）也可用 but … too / as well 替代 not only … but also 中的 but also .例如：

She not only sang well but danced gracefully too （or as well）

（8）not only A but also B = B as well as A， 但前者的強調重點在 B ；后者的強調重點也在 B .（漢譯時，要先譯 as well as 后面的詞）例如：

The child is not only healthy but also lively. （= The child is lively as well as healthy.）

這孩子既健康又活潑。

It concerns not only me but also you. （= It concerns you as well as me.）

這件事不但與我有關，而且也與你有關。
