how to explain to the phase

1. out of his depth : unable to understand something or in a situation where you have no control
能力以外
e.g. He feels totally out of his depth in his new job.

2. felt an added call to effort : felt a need to pay greater effort
覺得需要加把力

3. the door was thrown open : the door was opened whereas it was not open a moment before
特別強調之前門是沒有打開而現在打開了。

4. the dirty town took shape before him: the landscape of the dirty town gradually became visible
逐漸看得清楚

1.
Dr. Manson is completely OUT OF HIS DEPTH when he has to deal with realpatients for the first time and much of the illness that he is expectedto cure is in fact, caused by the poor living conditions of hispatients.
當萬爾臣醫生需要第一次救治真病人的時候，他感到力所不及。他大部份需要治療的疾病其實是由生活環境差而導致的。

2.
At once , a sense of power filled the mountain valley. Manson drew adeep breath . He felt AN ADDED CALL TO EFFORT , sudden hope and promisefor the future.
立刻，彷彿有一種力量注滿了那山谷。萬爾臣深深地吸了一口氣。他覺得有一種添加有他身上的使命感，去努力，對於未來突然的希望及承諾。

3.
The next Minute the front door was THROWN OPEN …
接着，正門猶如被爆開一樣打開了

4.
It was still raining as he crossed the black , rough ground and madehis way to the main street . Darkly , as he walked , the dirty townTOOK SHAPE BEFORE HIM.
當他橫過那黑暗，粗糙的地面而走向大街時，暗地裏，那個骯髒的城鎮在他來到之前開始變得像樣了。

好可能會譯得唔準
不過希望你滿意啦

Hi,
to be out of his depth = not to have the knowledge, experience, or skills to deal with a particular subject or situation.
AM ADDED CALL TO EFFORT=I guess it means
he felt like he had to face everything ahead.
( I am not sure of this idiom. I have never heard of it)

the front door was THROWN OPEN = the door 被大力打開
took shape before him = to assume a definite or distinctive form
在.他..面前 成形///;體現

. Hope that helps.
Bye
