===================語法常識回顧=================
1.ever since 的結構：(作為連詞)=since 完成時態---- ever since +主+動詞簡單過去式
例：I have known him ever since he was a child.
他從小我就認識他了。
這種用法同since 差不多，不過 ever since 比 since 用得少。
再如：We have lived in Shanghai ever since we came to China.(自從我們來到中國之后就住在上海。)
2.以上所說的 ever since 作為連詞。
ever since 也可作為副詞，解釋“此后”（就一直...）
例：1）He fell ill at Christmas and has been ill ever since.
他在圣誕節生病了此后就一直不適。（has + be ill）
2）He left home last year and has been away ever since.
他去年離家走了，此后一直在外面。（has + be away）
3）He fell off his horse a week ago and has been in bed ever since.
一周前他從馬背上跌下來，從那以后就一直躺在床上。
4）He went to Turkey in 1950 and has lived there ever since.
他在1950年去土耳其，此后就一直住在那里。
3. has not been able to 這實際上就是 be able to 加上 have 罷了。所謂 be able to 就是“有可能”不是“能”（can）。如果一直，始終沒有可能就是has not been able to ,這很簡單。
如果 it has not been easy. 就是“那件事一直不是輕而易舉的。”完成時態不一定都解釋為“已經”，有時要解釋為“一直”。

____________________不準停車___________________
Jasper White is one of those rare people who believes in ancient myths. He has just bought a new house in the city, but ever since he moved in, he has had trouble with motorists.
{賈斯珀·懷特是那種少見的相信古代神化的人之一。他在城市里剛買了一套新房，但自從他搬進去以來，他已經同汽車司機鬧上了糾紛。}
When he returns home at night, he always finds that someone has parked a car outside his gate.Because of this, he has not been able to get his own car into his garage even once. Jasper has put up "No Parking" signs outside his gate, but these have not had any effect.
{當他晚上回家時，他總是發現有人把一輛汽車停在他的家門口。由于這個原因，他連一次也沒能把他自字己的汽車開進車庫。賈斯珀已經不止一次地把“不準停車”的牌子掛在門口，但未曾起過任何作用。}
Now he has an ugly stone head over the gate. It is one of the ugliest faces I have ever seen. I asked him what it was and he told me that it was Medusa, the Gorgon. Jasper hopes that she will turn motorists to stone. But none of them has been turned to stone yet!
{現在他把一個丑陋的石頭人頭像放在大門邊，那是我見過的最丑陋的人面像之一。我問他那是什么，他告訴我那是美杜莎，是蛇發女怪。賈斯珀希望這女怪將會把汽車司機們變成石頭。可是至今還沒有一個人變成石頭呢！（美杜莎為蛇發女怪，誰要被她看到，誰就會變成石頭，這是希臘神話中的故事。）}
