剛才那些問題都可以換一個方式問, 比方護(hù)士問亨利: "你從來沒有得過高血 壓, 不是嗎?" You have never had high blood pressure, have you? 就是一個例 子.下面我們作一組練習(xí), 一方面復(fù)習(xí)時態(tài), 一方面復(fù)習(xí)我們剛才學(xué)的新詞匯.

請你注意聽護(hù)士問亨利問題; 這些問題亨利都一一地作否定的答覆, 在亨利回 答的時候, 請你也一起回答.

F: You have never had polio, have you?

M: No, I've never had polio.

F: You have never had tuberculosis, have you?

M: No, I've never had tuberculosis.

F: You have never had high blood pressure, have you?

M: No, I've never had high blood pressure.

F: You have never had a heart attack, have you?

M: No, I've never had a heart attack.

F: You have never had cancer, have you?

M: No, I've never had cancer.

F: You have never had serious diseases, have you?

M: No, I've never had serious diseases.

F: You have never had a long term illness, have you?

M: No, I've never had a long term illness.

下面我們作一組練習(xí)比較現(xiàn)在完成時態(tài)跟過去時態(tài). 以前我們學(xué)過過去時態(tài)是 用來表示在過去一個特定時間發(fā)生的事情; 而現(xiàn)在完成時態(tài)用來表示到目前已 經(jīng)發(fā)生的事情, 并不表明特定的時間. 在作下面這組練習(xí)的時候你會聽到醫(yī)生 用現(xiàn)在完成時態(tài)問凱特作過某些事情沒有, 這些問題凱特都一一的作肯定的答 覆, 并且用過去時態(tài)補(bǔ)充說明事情發(fā)生的確定時間是 "上個月". 現(xiàn)在我們開始 作練習(xí),在凱特回答問題的時候也請你一起回答:

M: You have had a health check-up lately, haven't you?

F: Yes, I have had a health check-up. I had it last month.

M: You have had a blood test lately, haven't you?

F: Yes, I have had a blood test. I had it last month.

M: You have had an x-ray lately, haven't you?

F: Yes, I have had an x-ray. I had it last month.

M: You have had an operation lately, haven't you?

F: Yes, I have had an operation. I had it last month.

M: You have had a blood transfusion lately, haven't you?

F: Yes, I have had a blood transfusion. I had it last month.

下面一組練習(xí)還是比較過去時態(tài)和現(xiàn)在完成時態(tài). 練習(xí)的內(nèi)容是說到醫(yī)學(xué)上 的成就. 首先你會聽到男老師念一個被動語態(tài)的過去時態(tài)句子, 比方: "去年 有許多人住院." Many people were hospitalized last year. 接著女老師就用現(xiàn) 在完成時態(tài)把句子改成 "從那以后有更多人住院." More people have been hospitalized since then. 這組練習(xí)里有些詞匯你可能不太熟, 比方 "實(shí)驗(yàn)" experiment, "技術(shù)" technique, "意外" accident, "避免" prevent, "成就" achievement 等等, 請你在聽老師念句子的時候一面注意時態(tài)的變化, 一面 注意這些詞匯. 現(xiàn)在我們開始.

M: Many people were hospitalized last year.

F: More people have been hospitalized since then.

M: Many people were treated last year.

F: More people have been treated since then.

M: Many people were saved last year.

F: More people have been saved since then.

M: Medical experiments were done last year.

F: More medical experiments have been done since then.

M: Modern techniques were learned last year.

F: More modern techniques have been learned since then.

M: Some accidents were prevented last year.

F: More accidents have been prevented since then.

M: A lot of patients were cured last year.

F: More patients have been cured since then.

M: Several hospitals were built last year.

F: More hospitals have been built since then.

M: Medical achievements were made last year.

F: More medical achievements have been made since then.
