【知識講解】
1，Once you have done this, you will quickly become a useful member of the team. 一旦你學會使用了，你就會很快地成為工作班子里有用的一員。
Once you have done this… 是承接上文來的，意思相當于：Once you have learned how to use every piece of equipment….
once 是從屬連詞，作"一(旦)……就……"(from the moment that)解，連接一個表示時間的狀語從句。例如：
Once you show any fear, the dog will attack you.
你一顯出害怕的樣子，狗就會來咬你。
Once he said that, I know he was lying. 他一說那件事，我就知道他在撒謊。
She wouldn't change her mind once she made the decision.
她一旦作出決定就不會改變的。
once 還可以作副詞，作"一次"(one time)或"曾經一度"(some time ago)解。例如：
I have been there once. 我到過那兒一次。
We go home once a week. 我們每周回家一次。
He once knew her, but they are no longer friends.
他曾經認識她，但是他們現在不再是朋友了。
Her father once worked in a car factory in Harbin.
她父親在哈爾濱一家汽車廠工作過。
2，It is better to ask for help at the beginning rather than to wait until a busy period when everyone is rushed off their feet. 最好在開始工作時就去請求幫助，而不要等到大家都忙得不可開交時再去找人幫忙。
1）rather than 而不是，與其……寧愿。這是一個連詞詞組，用來連接兩個并列的成分(如本句中連接兩個作主語的不定式短語 to ask for…和 to wait…)，表示在兩者中進行選擇，意即"是A而不是B"，"要A而不要B"，"寧愿A而不愿B"等。例如：
John must go rather than Jack.
必須去的是約翰而不是杰克。(連接兩個名詞 John 和Jack)
These shoes are comfortable rather than pretty.
這些鞋子穿起來很舒服，但并不漂亮。(連接兩個表語形容詞 comfortable和 pretty)
He'd prefer to come in August rather than in July.
他愿八月來，而不愿七月來。(連接兩個表示時間的介詞短語 in August和 in July)
I love swimming rather than skating.
我喜歡游泳，而不喜歡溜冰。(連接兩個 -ing 形式 swimming 和 skating)
I decide to write rather than (to) telephone.
我決定寫信而不打電話。(連接兩個不定式 to write 和 to telephone)
注意：當連接兩個不定式時，rather than 后面的這個不定式可以帶 to，也可以不帶 to，還可以用 -ing 形式。例如：
It's better to reply immediately rather than (to) wait till the weekend. (或rather than waiting till the weekend) 最好是立即回答，而不要等到周末。
We ought to check up, rather than just accept what he says. (或…accepting what he says) 我們應該核實一下，而不是他說什么就信什么。
2)rush sb．off his feet 意思是"使忙得個不亦樂乎"，"使忙得不可開交"，常以被動形式出現(sb is rushed off his feet.)，用于非正式文體。例如：
We were so busy in the office today. I was rushed off my feet.
今天我們辦公室里真忙。我是忙得不可開交。
They're rushed off their feet with the sowing. 他們播種忙得個不亦樂乎。
3， What is more, this"information line"operates 24 hours a day. 再說，這條"問訊線路"是一天24小時工作的。
"What is more"是一種固定表達，作"再說"、"而且"、"更有甚者"解，在句中作插入語，表不除了上文所說的情況外還有進一步的情況。例如：
He came home after midnight, and what's more, he was drunk.
他后半夜才回家，而且醉醺醺的。
----Why didn't you go and see Mr Johnson? 你為什么沒去看看約翰遜先生呢？
----Because it was raining hard that day. And what's more, I didn't have his address with me. 因為那天下大雨，再說，我身邊又沒有他的地址。
4，It was important to carry out the work quickly, so an extra team of men were asked to work on the repairs one evening. 加快完成這項工作很重要。因此，有一天晚上要求多派了一隊人來搞維修工作。
work on 是短語動詞，作"從事(某工作)"、"致力于"解，可以有多種譯法。這個短語動詞中的on是介詞，后跟名詞、代詞或 - ing 形式。例如：
They are working on a report of the experiment. 他們在寫一份實驗報告。
We worked on this day and night. 我們日日夜夜都在從事這項工作。
He is still working on inventing a new type of machine for office work. 他仍在致力于發明一種辦公用的新式機器。
Many people in China are working on a"Project Hope", helping poor children to go to school. 中國有許多人正在從事一項"希望工程"，幫助窮苦孩子上學。
work on 也可以作"繼續工作"(work continuously)解，其中的 on是副詞，表示"繼續地"。如 walk on(繼續走)， stay on(繼續逗留)，talk on(繼續談話)等。例如：
I'll have to work on till the report is ready. It is needed for tomorrow's meeting. 我不得不繼續工作，直到把報告寫好為止。這篇報告明天會議上要用的。
5，There had been fuel on the ship, but this did not appear to have caused the fire, and little smoke was produced. 船上有一些燃料，但看來并不是燃料引起火災的，而且幾乎沒有產生煙。
1)There had been fuel…，謂語動詞用了過去完成時態，這是因為上文的時態用了一般過去時的緣故。… they at once started to look for causes of the fire. They were puzzled by…。這說明在消防隊員尋找失火原因之前(過去)，船上就已經有了燃料(過去的過去)。
2)… but this didn't appear to have caused the fire…句中 appear作"似乎"、"顯得"解，后跟不定式的完成式，這表示不定式的動作是在謂語動詞所表示的動作之前發生的。如果將原句作如下改寫，則可以看出兩個動作的先后：
It seemed that this had not caused the fire. 又如：
She appeared to have heard about it already. (It seemed that she had already heard about it.) 她似乎已經聽到這件事了。
He didn't appear to have fixed up the pipe. (It seemed that he hadn't fixed up the pipe.) 看來他并沒有把管子安裝好。
6，It must have been a gas that could burn but that would not explode, a gas that did not smell strong, and a gas that did not kill people. 這準是一種能夠燃燒但不會爆炸的氣體，一種氣味不大又不傷人的氣體。
1)這是一個復合句。主句是 It must have been a gas。這是一個"主系表"結構，表語是三個 a gas，后面都跟著由關系代詞 that引導的定語從句。
2)句中must用來表示推論或揣測，作"一定是"、"準是"、"想必"解。must后跟不定式的完成式(must have + 過去分詞)表示對過去發生的事情的揣測。例如：
The house was burned down. There must have been some cause.
房子燒了，準是有什么原因。
Jim kept crying last night. He must have had some problem.
吉姆昨晚哭個不停，他準是有什么問題。
Miss Black didn't come yesterday. She must have been ill.
布萊克小姐昨天沒有來，想必她病了。
【語法】
1，動詞不定式，動詞-ing形式和過去分詞作表語的用法，要注意以下幾點：
1）不定式作表語有時可以省略to;
2）現在分詞作表語表示主動和進行；
3）過去分詞作表語表示完成和被動。
例如：
The machines seems to have been used already. Can you find me a new one?
The tap is broken. Can you go to the stores and get another one?
The difficulty is finding people with the right education.
The only answer for us is to mark all the supply lines in the port clearly.
It only remains for me to thank the whole team for their hard work.
All I could do was call for help.
2, 常用系動詞分類
（1） 純系動詞：be, become, seem等。
（2） 兼實義動詞的系動詞
（a） 感官動詞：look, feel, smell, taste, sound等。
（b） 表示"變"：get, grow, turn, go ,run等。
（c） 實義詞詞義基本沒有變化的：stay, lie, stand, fall, prove等。
3, 情態動詞與實義動詞的區別
構成否定句，疑問句是否需要助動詞
是否有單數第三人稱詞尾
其后接帶to 不定式還是接不帶to 不定式
情態動詞

注意：1．have to 結構構成否定式、疑問式時，需要助動詞。
2．have to, ought to 中的to 不能省略，且直接接原形動詞。
3．don't have (to) do 結構中，不定式符號to 可以省略。

【例題解析】
1．The Olympic Games, ______ in 776 B.C., Did not include women players until 1912．
A．first playing B．to be first played
C．first played D．to be first playing
【答案】C
【解析】全句意思是"第一次奧林匹克運動會是在公元前776年舉辦的，但是到公元1912年才有女運動員參加"。奧運會是被舉辦的，選擇表示被動的，所以選B和C。又因為776 B.C.（公元前 776年）是表示過去的時間狀語，而動詞不定式短語常表示將來的動作，所以應選擇C。這里played是過去分詞，作定語，相當于which was first played。
2． ______ in thought, he almost ran into the car in front of him.
A．Losing B．Having lost
C．Lost D．To lose
【答案】C
【解析】句子意思是"沉思中，他差點撞上前面的汽車。"（be）lost in thought（想得出神）是固定搭配，另外，表達此意時，還可以有 lose oneself in thought。
3．The patient was warned ______ oily food after the operation.
A．to eat not B．eating not
C．not to eat D．not eating
【答案】C
【解析】醫生告誡病人手術后不要吃油膩的食物。warn sb. （not）to do sth. 是常用句型，此句用被動語態，即：sb. is（was）warned（not）to do sth.。
4．Paul doesn't have to be made ______ . He always works hard.
A．learn B．to learn
C．learned D．learning
【答案】B
【解析】沒有必要督促保羅念書。他一直是很用功的。make sb.do意思為"迫使某人做"。該句是被動語態，不定式learn作主語補足語，應加上to。
5．We agreed ______ here ,but so far she hasn't turned up yet.
A．having met B．meeting
C．to meet D．to have met
【答案】C
【解析】我們約定在這兒見面，但她到現在還沒來。動詞agree只接不定式作賓語，不可以接動名詞作賓語。所以答案在C和D中選擇。不定式一般式 to meet表示動作發生在 agree之后或與 agree同時發生，而完成式 to have met則表示該動作發生在agree之前，與題意不符，故答案為C。
