中級美國英語復習現(xiàn)在完成時態(tài)
一.本課要點及示例
在這一課里, 我們復習現(xiàn)在完成時態(tài), 同時也要學習一些醫(yī)藥方面的詞匯.首先我們聽一段對話, 內容是說凱特和亨利談到醫(yī)藥保險的事情. 請你注意英文老師的發(fā)音和語調.
F: Our health insurance bill came yesterday. The cost has increased again.
M: Again? We have had two increases this year.
F: Medical care has been so expensive lately.
M: Remember when Peter was in the hospital after his accident last year?
F: I sure do. The hospital bill for that was over three thousand dollars; and how much did the doctor charge us?
M: I don't remember. But our insurance paid for all the bills.
F: And Peter got excellent care at the hospital, didn't he?
M: Yes, he did. I guess I can't complain about the money we have paid for health insurance all these years.
現(xiàn)在我們來聽英文老師用慢速度把對話再念一遍.
F: Our health insurance bill came yesterday. The cost has increased again.
M: Again? We have had two increases this year.
F: Medical care has been so expensive lately.
M: Remember when Peter was in the hospital after his accident last year?
F: I sure do. The hospital bill for that was over three thousand dollars; and how much did the doctor charge us?
M: I don't remember. But our insurance paid for all the bills.
F: And Peter got excellent care at the hospital, didn't he?
M: Yes, he did. I guess I can't complain about the money we have paid for health insurance all these years.
下面老師再把對話里的現(xiàn)在完成時態(tài)句子念一遍.
F: The cost has increased again.
M: We have had two increases this year.
F: Medical care has been so expensive lately.
M: I can't complain about the money we have paid for health insurance all these years.
二.現(xiàn)在完成式
從上面那些句子你可以聽出來, 現(xiàn)在完成時態(tài)是用 has 或是 have加上動詞的過去分詞構成的. 這種時態(tài)可以用來表示 "經(jīng)驗",比方 "我得過心臟病" I have had a heart attack 等等; 在問句里人們常常用 ever, e-v-e-r, ever 和現(xiàn)在完成時態(tài)問別人從過去到現(xiàn)在是不是有過某種經(jīng)驗, 比方: "你輸過血嗎?" Have you ever had a blood transfusion?
下面我們作一組代換練習, 學學這類句子.練習的作法是由老師問你一個問題,比方 "你檢查過身體嗎?" Have you ever had a health check-up? 接著老師念一個字或詞, 比方 "驗血" a blood test, 你就把這個詞代換到原來的句子里. 在作練習的時候你可以學到不少跟醫(yī)療或疾病有關系的字或詞, 比方 "手術" an operation, "X光" an x-ray, "癌癥" cancer, "小兒麻痹" polio, "肺病" tuberculosis 等等. 現(xiàn)在我們開始作練習, 每作完一句, 老師就把正確答案念一遍給你聽.
M: Have you ever had a health check-up?
M: a blood test
F: Have you ever had a blood test?
M: a blood transfusion
F: Have you ever had a blood transfusion?
M: an operation.
F: Have you ever had an operation?
M: an x-ray
F: Have you ever had an x-ray?
M: serious diseases
F: Have you ever had serious diseases?
M: high blood pressure
F: Have you ever had high blood pressure?
M: a heart attack
F: Have you ever had a heart attack?
M: cancer
F: Have you ever had cancer?
M: polio
F: Have you ever had polio?
M: tuberculosis
F: Have you ever had tuberculosis?
M: medical treatment
F: Have you ever had medical treatment?
M: medical care
F: Have you ever had medical care?
剛才那些問題都可以換一個方式問, 比方護士問亨利: "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, 一方面復習時態(tài), 一方面復習我們剛才學的新詞匯.請你注意聽護士問亨利問題; 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比較現(xiàn)在完成時態(tài)跟過去時態(tài). 以前我們學過過去時態(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,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.
下面一組練習還是比較過去時態(tài)和現(xiàn)在完成時態(tài). 練習的內容是說到醫(yī)學上的成就. 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. 這組練習里有些詞匯你可能不太熟, 比方 "實驗"experiment, "技術" 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.
現(xiàn)在我們再來復習現(xiàn)在完成時態(tài). 下面一組練習是由老師用疑問詞提出被動語態(tài)問句,接著老師念出一個詞組,請你用老師給你的詞組來回答問題. 每回答一句就請你聽老師念正確答案.
M: What have been done?
M: medical experiments
F: Medical experiments have been done.
M: What have been learned?
M: modern techniques
F: Modern techniques have been learned.
M: What have been prevented?
M: some diseases
F: Some diseases have been prevented.
M: What have been built?
M: several hospitals
F: Several hospitals have been built.
M: What have been made?
M: medical achievements
F: Medical achievements have been made.
在今天這一課的對話里, 亨利和凱特談到了去年彼得住院的事情. 下面這組代 換練習的內容就是說到彼得去年在醫(yī)院的時候, 那家醫(yī)院設備非常好, 他的醫(yī)藥保險所包括的項目很周全等等. 練習的作法是老師先念一個句子, 接著老師提出一個名詞或是形容詞, 請你把你所聽到的代換到句子里適當?shù)牡胤? 在這一組練習里你可以學到一些有用的詞匯,比方"醫(yī)院設備"hospital equipment,"保險范圍" insurance coverage, "保險費" insurance premium 等等. 現(xiàn)在我們開始作練習, 每作完一句還是請你聽老師念正確答案.

三.聽短文回答問題
今天我們要聽的文章說到美國的醫(yī)學成就和醫(yī)藥保險. 比方美國很多私人公司為員工設立了保健計劃; 一般人也可以按月交保費給保險公司, 有大病的時候醫(yī)藥費用由保險公司來負責.另外還有一些大的醫(yī)療機構 辦的健康保險,會員也是按月交保費, 有重病的時候就在醫(yī)療機構附設的醫(yī)院治療, 費用由醫(yī)療機構負責. 至于年老貧困的人, 政府也有醫(yī)藥照顧計劃.現(xiàn)在請你注意聽.
Americans are proud of the medical achievements made in this country. Medical scientists have found cures and prevention for such diseases as polio and tuberculosis. They have learned a great deal about cancer and heart disease. Many lives have been saved. American hospitals are the most modern and best equiped medical facilities in the world. But this degree of excellence has been expensive. Medical costs in the United States are very high. There is no national health plan for Americans. But there are many programs available for this purpose. Many people have health plans at the companies where they work. Under these plans, the company pays a fixed sum of money regularly into a fund. Then when the employee needs medical help,he can use money from the fund to pay for it. Other people have health insurance. They pay insurance premiums each month to insurance companies which then pay for medical expenses when they are needed. In some medical plans, the insurance company is also the medical institution. People regularly pay the hospital directly. Then when they need medical treatment, they go to the hospital without paying more money. The government has health insurance programs for older people, poor people and those with long term illness. These programs make medical care available to those without their own health insurance.
剛才那篇文章你都聽懂了嗎? 如果沒有, 等一會兒你還有機會聽. 現(xiàn)在老師先把今天測驗的三個問題念一遍.
第一個問題是:
M: What have American medical scientists done?
第二個問題是:
M: How do Americans pay for health costs?
第三個問題是:
M: Who are helped by government health insurance programs?
現(xiàn)在我們再聽英文老師用慢速度把整篇文章念一遍, 請你特別注意剛才那三個問題的答案.
