when 可與一個點的時間或表示一段的時間連用，從句動詞可以是短暫性或延續性動詞；

⑻ 人教版八年級英語下冊第三單元單詞解析
quite和very都是程度副詞，都可修飾形容詞和副詞，都是「非常」的意思，但是quite可以直接修飾動詞，very不能直接修飾動詞。例如：
She is quite busy.
She is very busy.
happen; take place 雖都意為「發生」，但happen一般指偶發事件，而take place則指事先計劃好的事情。二者均是不及物動詞。不能用於被動語態。試比較：
When did the accident happen? 事故是什麼時候發生的？
The May 4th Movement took place in 1919. 五四運動發生於1919年。
shout表示因高興、驚奇、贊揚時發出的喊叫；而cry則表示因痛苦、恐懼、委屈等而「大喊」或「哭叫」。請比較：
Father shouted at the girl, and the girl cried. 爸爸訓斥了那女孩一頓，女孩哭了。
when; while; as這三個詞都可以用作連詞，表示「當……的時候」，但用法有所不同：
① when表示瞬間，也可指一段時間。主句和從句中的動作可以同時發生，也可以先後發生。如：
When he saw her, he waved. 他一看見她就擺了擺手。
② while用於表示一段較長的時間或一個過程，強調主句的動詞和從句的動詞表示的動作或狀態是同時發生的，常對同類的兩個動作進行對比。如：
Please write while I read. 我讀的時候，請寫下來。
③ as常可以與while互換，但它著重指主從句的動作同時發生，而不是一前一後，可譯為「一邊……一邊……」。如：
They talked as they walked. 他們邊走邊談。
kill和murder: kill是泛指導致某人或某物死亡：The cold weather killed our flowers.寒冷的天氣凍死了我們的花。而murder則是懷著目的殺死某人：She was sent to prison for murdering her husband.她因為殺死她丈夫而被判入獄。
remember doing記得過去曾經做過某事：I remember returning that book to her.我記得已把那本書還給她了。
remember to do sth.記得去做某事：Please remember to return that book to her.請記得把那本書還給她。
remember me to…請向……致意：Please remember me to your family.請代我向你的家人問好。
in hospital指「因病住院」，即醫院的專門作用是治病，而句子所指的人或物正在接受醫院的治療。in the hospital指「在這家醫院里」但不接受醫院的治療，與醫院的專門作用無關，比如就職的醫生、護士、清潔工等。
in front用在動詞後面，做狀語，表示「在前面」。如：
He sits in front.他坐在前面。
in front of在……前面（在某個范圍外面）。如：
There is a tall tree in front of the house.房子前面有一棵大樹。（樹在房子外面的前面）
in the front of在……前面（在某個范圍內部的前面）。如：
We can see a desk in the front of the classroom.我們看見一張桌子在教室前面。（桌子在教室的內部的前面）
when和while都引導時間狀語從句。其意思為「當什麼時候」，表示正在進行的某個動作。其區別在於：
when引導的從句中的謂語動詞可以是短暫性或延續性動詞，或表示狀態動詞。while引導的從句中的謂語動詞只能是延續性動詞，或表示狀態動詞。如：
When he came back, I was sleeping.（come是短暫性動詞，只能用when引導。）當他回來時，我正在睡覺。
While /When he was working, he saw an accident happened.（work是延續性動詞，可以用when或while）當他在工作時，他看見發生了一場事故。
注意：這兩者最基本的區別是，如果主從句動詞都是用了進行時，只能用while。而主從句的動詞都用的是一般時，則用when。如：
When he came in, I went out.（這里只能用when）
While he was working, I was reading.（這里只能用while）
another表示「另一個。又一個」，是泛指另外一個．並不是兩者中的又一個。the other和other都表示「其他人或物」，但the other，指其他的全部，而other指其他的一部分。
in a tree 和on a tree意思都是在樹上，但具體所指內容不一樣；in a tree指的是樹以外的東西，也就是說不是樹本身長的東西（如：人、動物等）在樹上。on a tree指的是樹木本身的一部分（如：樹葉、樹的果實等）在樹上。
「when」表示「在……時」。它表示兩個動作一先一後地進行，可以用來指某個時間點（動作瞬間完成），也可以表示一段時間（動作有延續性）。
「while」表示同時，表示兩個動作同時進行，它不能表示某個時間點。
例如：It was raining when we arrived．（時間點）我們到達時天正下雨。
My mother got home when I was doing homework.
（時間段）我正寫作業時我媽到家了。
He fell asleep while he was doing exercises.
（時間段）他在做練習時睡著了。
reach是及物動詞，後面直接跟地點名詞；
They reached London.他們到達了倫敦。
get是不及物動詞，後跟名詞時要加介詞to；
Can we get to the station in time?我們能夠及時趕到車站嗎?
arrive是不及物動詞，後跟名詞時要加介詞in或at。
At what time did you arrive at the station?你是幾點鍾到火車站的?
2.Well，I was standing in front of the library.
