5、vehadtwoincreasesthisyear. F: Medicalcarehasbeensoexpensivelately. M:Ican'tcomplainaboutthemoneywehavepaidforhealthinsurancealltheseyears.二.现在完成式 从上面那些句子你可以听出来,现在完成时态是用has或是have加上动词的过去分词构成的. 这种时态可以用来表示"经验",比方"我得过心脏病"Ihavehadaheartattack等等;在问句里人们常常用ever,e-v-e-r,ever 和现在完成时态问别人从过去到现在是不是有过某种经验
6、, 比方: "你输过血吗?"Haveyoueverhadabloodtransfusion? 下面我们作一组代换练习,学学这类句子.练习的作法是由老师问你一个问题,比方"你检查过身体吗?"Haveyoueverhadahealthcheck-up? 接着老师念一个字或词,比方"验血"abloodtest,你就把这个词代换到原来的句子里. 在作练习的时候你可以学到不少跟医疗或疾病有关系的字或词, 比方 "手术"anoperation,"X光"anx-ray,"癌症"cancer,"小儿麻痹" polio, "肺病"tuberculosis等等.现在我们开始作练习,
7、每作完一句,老师就把正确答案念一遍给你听. M:Haveyoueverhadahealthcheck-up? M:abloodtest F: Haveyoueverhadabloodtest? M:abloodtransfusion F: Haveyoueverhadabloodtransfusion? M:anoperation. F: Haveyoueverhadanoperation? M:anx-ray F: Have
