①I advise you to take the chance.我建議你抓住機會。
②-What do you advise me to do?你建議我怎么辦？
-I advise you not to lose heart; just keep on.我勸你不要灰心，繼續(xù)干。
advise 還可同suggest一樣，后接名詞、代詞、動名詞（短語）和that從句（用虛擬語氣）作賓語。
①-What would you advise?你有什么建議嗎？
-I advise you an early start我建議你早點出發(fā)。

The doctor persuaded my father to give up smoking.醫(yī)生說服我爸爸戒了煙。
The doctor advised my father to give up smoking, but failed.
醫(yī)生勸我爸爸戒煙，但沒成功。
advise; suggest
advise 與suggest 都可作"建議"講，二者用法有同有異。
(1)相同點
表示建議做某事，advise與suggest都可采用下列三種句型:
① + 名詞
② + 動名詞
③ + that從句（從句中常用should加動詞原形，should可以省略。）
eg. He advised/ suggested an early start.
He advised/ suggested (our) starting early.
He advised/ suggested that we (should) start early.
(注：只要是用從句表示建議該做的事，從句中就可用"should+動詞原形"，should可以省略。)上面的第三句可轉化為：
It was suggested that we (should) start early.
What he suggested was that we(should) start early.
His suggestion was that we (should) start early.
(2)不同點
①advise后可以跟人稱代詞作賓語，而suggest后不可以跟人稱代詞作賓語。故可以說：
advise sb. to do sth.; advise sb. against (doing) sth.; advise sb. on/ about sth.; suggest(to sb.)that...
前三種結構中不可將advise改為suggest，如：
他建議我們去參觀博物館。
[正]He advised us to go to visit the museum.
[誤]He suggested us to go to visit the museum.
[誤]He suggested us that we go to visit the museum.
②suggest還有"暗示、表明、說、指出（一個事實）"的意思。此時從句中用陳述語氣，不用虛擬語氣。如：
The smile on his face suggested that he was pleased.
Having examined carefully, the doctor suggested that the patient was seriously ill.(句中suggest陳述了一個事實，故用陳述語氣。)比較：
Having examined carefully, the doctor suggested that the Patient be
operated on at once.(句中suggest表示建議該做某事，從句中用should加動詞原形，should在從句中省略。)
affect（=have an effect on sth.）vt.影響（effect n.影響）
This may affect your health.
這或許會影響你的健康。
My throat is always affected by bad weather.
我的嗓子總是受惡劣天氣的影響。

2）"be afraid of doing sth"意為"擔心，害怕……"。

4）"be afraid that…"意為"擔心，恐怕"。
5）"be afraid to do "意為"害怕，擔心而不敢做某事"。
6）I'm afraid so/not.恐怕是這樣/恐怕不會這樣

appear;seem;look
appear, seem, look都有"看起來似……"之意，但其暗含意思和用法又各有不同。
從意義上講：
(1)appear強調外表給人的印象，有時含實質上并非如此的意思，如：
He appears to know more than he really does。他看起來好像懂得很多。（其實懂得沒有那么多）
(2)seem暗示有一定根據的判斷，這種判斷往往接近事實，如：
His health seems to be better.
他的健康狀況似乎有所好轉。

He doesn't look his age.
他看起來比實際年齡年輕（或老成）。

=It seems that he is very sad today.
