During my first seven semesters as a medical student at Gadjah Mada University in Indonesia , I spe nt most of my time study ing and in classrooms .I rarely spoke with real patie nts in a hospital sett in g.The n last year I started visit ing the n eurology （神经）ward at Dr.Sardjito Hospital.I was gathering data for my paper.At the hospital I would review the medical records of newly admitted stroke patie nts , the n in terview them to find out if they were tak ing the pill.
One cold , rainy evening last October , I was in the neurology ward desperately “ huntingthe for final three patients I needed to plete my study.The records showed that there was a 43-year-old stroke patient , 13 . 14 . 15 . 16 . 17 .

whom I will call Ms A , in the ward.Holding a patient questionnaire , I went into her room.I asked how she was doing.She softly replied that she was getting better but the left side of her body was still weak.After I finished the questionnaire , I prepared to leave so I could go through more medical records.Before I could stand up , Ms A started making conversation , asking where I was from and why I was work ing so late in the evening」was surprised some one in her con diti on would want to talk.
Ms A started talking about herself.She told me she had three children in primary school , who were stay ing with a n eighbor.Her husba nd died a year ago and she is the sole breadw inner of her famil y.I did n't know what to say.I just sat quietly while she talked.Without realiz ing it , I had begu n holdi ng Ms A's hand.
The conversation went on like this for about 20 minutes.A few days later , when I returned to the ward , I discovered that Ms A had been discharged as her condition had improved.
Ms A taught me one of the most important lessons a doctor can leann.Sometimes patients do not n eed expe nsive medici ne or state-of- the-art tech no logy.They just n eed some one with the patie nee and willingness to lend an ear and spare a little of their time.

Three Strategies to Enhance Your Reading
and Learning prehension
Reading prehension strategies help a lot in developing your vocabulary and power of analysis.__1__ ☆Role-playing.
It allows you to gain a better viewpo int over the text you have just read .It also gives you the freedom and flexibility to show your own understanding of the reading material.However , this kind of strategy does not apply to all texts.__2__
☆Check whether you have understood the material.
A lot of teachers like to hold questi on and an swer sect ions at the end of the less on to see how much a student actually remembers and understands.__3_ Closed questions are those immediately answerable by “ yesd'r “ no.” This will give the teacher a quick evaluation of how much the student has gathered from the less on. Ope n-en ded questio ns, on the other hand, are an excelle nt weigh of the student's reading prehension.Questions that begin with “ how”nd “ why'often push the student to details. ☆4
By tapping into what you've already known , you can make it easier to relate to what you're reading now.This strategy requires you to be up- to-date as well.Or at least , be a quick thinker.After all , you're expected to take advantage of any opportunity you have to tie one idea to another.__5__ A. Develop a good reading habit. B. Make use of prior knowledge or experienee. C. These questions should be both closed and open^ended. D. With these strategies , you'll be able to learn better and help others as well. E. The students should learn to ask themselves different questions after class. F. Teachers often use different reading prehension strategies to help their students understand the less on.
I am writing to ask for[DD)] whether you are able to do me a favor.I want to have a pen pal, the similarly hopefully a girl in her early twenties, and with interests si m ilar to mine.In my in teresti ng G . I suggest this reading prehension strategy be limited to texts with actual characters and story plots.
