Now,answer the following questions.

_____ The narrator might be a _______. (A) college student (B) high school student (C) college instructor (D) high school teacher

C

Some time ago, I received a call from a colleague who asked if I would be the referee on the grading of an examination question.

receive/make a (phone) call 　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　接 / 打電話

who 引導關係代名詞子句，修飾先行詞。

Next


grade (v.) grading 動名詞grade 當動詞時表「為 ( 考試等 ) 評分；為 ( 學生 ) 打分數」例：The teachers are busygrading term papers. Next


S + ask/wonder/want to know... + if-/whether-clause間接問句 (indirect speech)原句 =→ ...a colleague asked, “Will you be the referee on the grading of an examination question?”

He was about to give a student a zero for his answer to a physics question, while the student claimed he should receive a perfect score and would if the system were not set up against the student.

be about to 　正要… ( 表即將發生 )• Be quiet. The class is about to begin.

Next


while 為連接詞，表「然而」之意，相當於whereas ，置於主要子句後。• Sam was poor, while his brother was very rich.• Some people like fatty meat, while others hate it. Next


a perfect score = full marks 　滿分

Next


set up 　制定 ( 制度等 ) ，建立 ( 組織等 )• The Transport Ministry has set up a committee to investigate the accident.

Next


原句 (indirect speech)= → ...the student claimed, “I should receive a perfect score and would

(receive a perfect score) if the system were not set up against me.”(direct speech)

The instructor and the student agreed to submit this to an impartial judge, and I was selected.

agree to + V 　同意 ( 做 )…• He has agreed to do the task.agree with + sb 　同意 ( 某人 )• John agreed with me.agree on + sth 　同意 ( 某事 )• It's wonderful that both countries agreed on the peace plan.

Next

The instructor and the student agreed to submit this to an impartial judge, and I was selected.

另有一個有趣的說法 agree to disagree ，是用於「當各方都肯定不會改變意見」的時候。• After feverishly arguing for 3 hours, we all agreed to disagree.

Next

I went to my colleague's office and read the examination question: “Show how it is possible to determine the height of a tall building with the aid of a barometer.”

It is Adj + (for sb) + to V....• It is nearly impossible to find a parking space during the rush hours.

Next

determine 一般表「決定 ( 去做某事 ) 」，接不定詞。於此是表「確定；測定」，接名詞、名詞片語或名詞子句。例﹕determine the position of a star/the cause of the accident• Have you determined whom you'll invite to the party? Next


with/without the aid of... 　憑藉 / 不借助…的幫忙• The old man gets about with the aid of a walking stick.• This job would be impossible without the aid of a computer.


Next


barometer 「氣壓計」是義大利人Evangelista Torricelli 在 1643 年發明的一種水銀氣壓計。 1648 年，法國人 Pascal觀測到氣壓與高度變化的關係。

The student had answered: “Take the barometer to the top of the building, attach a long rope to it and lower the barometer to the street.

作者在看到考卷時，學生已經作答完畢，因此用過去完成式，表示更早的動作。• They had changed their clothes before the party started.

Next


attach...to... 　給…繫上…，給…裝上…• The man will attach the label to your luggage.• I attached the printer cord to my computer. Next

類似用到介係詞 to 的動詞用法尚有：tie...to... 　將…綁於…Dad tied the dog to the tree near our camp.pin...to... 　把…釘在…He pinned the note to the door so that his roommate would see it.fasten...to... 　把…固定於…John fastened his bike to the top of his car when going on a road trip.


Lower (v.) … …放下，降低的位置• lower a blind/flag放下百葉窗 / 降下旗子• The woman lowered a bucket into the well to get some water.

Then bring it up and measure the length of the rope. The length of the rope is the height of the building.”

I pointed out that the studentreally had a strong case for full credit, since he had answered the question completely and correctly.

point out 　指出• The newspaper pointed out that the government should help the poor.

Next


have a strong case for... 　有充分理由…make out a case for/against... 　提出贊成 / 反對…的理由• They made out a good case for lowering the price.• The scientists made a case for/against building another power plant.

Next


since 乃連接詞，表「既然…，因為…」 .• Since we aren't going to see the movie, we have time to enjoy a nice meal.

On the other hand, if full credit were given, it could well contributeto a high grade for the student in his physics course.

on the other hand 從另一方面而言，通常當要陳述兩種對比的觀點時，第一個觀點會用 on the onehand 點出，第二個觀點則由 on the otherhand 帶出。• On the one hand, bringing an umbrella on a sunny day is weird; on the other hand, if it suddenly rains it will be very useful. Next

contribute to... 　有助於；助長，促成• Penicillin has contributed greatly to the welfare of mankind.• Sugar contributes to tooth decay.


Next


(get) a high/good grade in + 科目• Helen always gets a good grade in English.• He received a failing grade on the term paper. 　 (on + 作業或報告 )

A high grade is supposed to certifycompetence in physics, but the answer did not confirm this.

be supposed to 有三種不同的語意：1. 一般認為 A high grade is supposed to certify competence in academic work.2. 有義務…，應該 You're not supposed to smoke here.3. 意圖是，旨在 This law is supposed to help the poor.

I suggested that the student have another try at answering the question.

S1 + suggest/order/insist/advise/require/request/demand + that + S2 (should) + V• The teacher recommended/insisted/ requested that she finish her paper as soon as possible.該句型的否定用法不加助動詞 do• I insisted that he not come home until I finished making dinner.

Next

I suggested that the student have another try at answering the question.

have/make a try (at + V-ing/N) = give sth a try 　試著 ( 做 )…• You should have a try at learning more than one foreign language.• I've never hang-glided before, but I want to have a try at it.• She gave the perfume a try.

I was not surprised that my colleague agreed, but I was surprised that the student did.

did 代替前面的動詞 agreed ，以避免重複。

I gave the student six minutes to answer the question, with the warning that his answer should demonstrate some knowledge of physics.

At the end of five minutes, he had not written anything. I asked if he wished to give up, but he said no.

at the end/beginning of + 時間　在…底 / 初at the end/beginning of the year 　在年底 / 初wish to + V... 　 ( 可能的話 ) 想要( 做 )…• I don't wish to be treated like a child anymore. Next

At the end of five minutes, he had not written anything. I asked if he wished to give up, but he said no.

I asked if he wished to give up, but he said no.→ I asked, “Do you wish to give up?” He said, “No.”

He had many answers to this problem; he was just thinking of the best one.

think of... 　思考，考慮• What did you think of the story?• I thought of buying you something but I didn't know what to get.

I excused myself for interrupting him and asked him to go on.

excuse oneself for V-ing 　為某事道歉• I excused myself for arriving so late.

go on (+ V-ing) 　繼續做• He went on dozing off in class regardless of his teacher's warning.• The man went on talking even though the movie had started.

In the next minute, he dashed off his answer which read:

dash off 　(1) 快速地寫，倉促地寫 • Ken dashed off his paper and turned it into the teacher.• Mom dashed off a list of groceries for me to buy.(2) 匆忙離去• Dash off now or you'll be late for the train.

Next

In the next minute, he dashed off his answer which read:

read 寫著• The sign reads, “Puli 30 kilometers.”

“Take the barometer to the top of the building and lean over the edge of the roof.

Drop the barometer, timing its fall with a stopwatch.

現在分詞構句 (timing...) 表示一前一後緊接著的動作。time (v.) 測量…的時間• Time how long it takes you to answer the questions.• The swimmer was timed at 50 seconds.• “How long does it take to get to the station from here?” “I don't know, I've never timed it.” Next

Drop the barometer, timing its fall with a stopwatch.

Drop the barometer, timing its fall with a stopwatch.→ Drop the barometer and time its fall with a stopwatch.

Next

Then, using the formula S = 1/2at2, calculate the height of the building.”

現在分詞構句 (using...)表示分詞構句的動詞 use, 與主要子句的動詞 calculate 同時發生的動作。

Next


S=1/2at2 為伽利略在十七世紀時所提出的公式，他先在木板上刻了光滑的凹槽，然後把木板的一頭抬高。讓小球從上向下自由滾動，並且記下每次運動時間和距離的關係。他不斷地改變木板的長度和傾斜角、測量時間和距離，證實小球運動的速度和時間成正比。而運動距離和時間的平方成正比就是等加速度運動的定律，即 S=1/2at2， S 為「距離」， a 為「加速度」， t 為「時間」。伽利略發現這個原理時，只有 17歲。

Next


原句 =→ Then, use the formula S=1/2at2 and calculate the height of the building.

At this point, I asked my colleagueif he would give up. He conceded,and I gave the student near maximum credit.

point 時刻，瞬間• The man was at/on the point of death when the rescuers found him.• They had reached the point when there was no money left.

Next

At this point, I asked my colleagueif he would give up. He conceded,and I gave the student near maximum credit.

原句 =→ At this moment, I asked my colleague, “Will you give up?”
