People's attitude toward drugs varies from person to
person. Some regard it as miraculous; others think of __1__
them as dangerous. Then what is the sensible attitude
toward drugs? I think the first thing to think is the __2__
difference between drugs and wonder drugs. The
antibiotics can really treat certain bacterial diseases. __3__
On the other hand, the major diseases threatening
Americans today are cancer, stroke, high blood
pressure, coronary disease, etc. Against them, the
doctor's bag of tricks is limited. He has wonder __4__
drugs. So the first important lesson is not to expect
too many from drugs. If you can accept the fact __5__
that the war against many of our most devastating
diseases is, at best, a holding operation more than __6__
an inevitable triumph, they will do a great deal to __7__
ease your own life as well as that of your doctor.
Too many patients exert great pressure on doctors
to describe for every symptom, even when such __8__
treatment is unwarranted or dangerous.
Unfortunately, the medical profession is guilty of
taking part, to a certain extent, in the wrongful
action. The patient who demands a short of penicillin
for every sniffle and sneeze may be given an injection __9__
by a reluctant physician because he is certain that
if he does not , the patient will not search until he find __10__
a doctor who will.

答案：
1. it——them
them指代上文的drugs
2. 在think和is之间加of或about
此处为不及物动词，一般在后面跟of或about
3. treat——cure
cure特别用以指病后通过治疗得以恢复健康；treat则只强调治疗本身
4. 在wonder前加no
根据上下文意义，医生没有治愈上文提及的各种疾病的特效药
5. many——much
用much指代“期望”这一抽象的概念性的东西
6. more——rather
此处不是比较概念，而是否定概念“不是”
7. they——it
it指代上文的the fact that the war against many of our most devastating
diseases is, at best, a holding operation more than an inevitable triumph.
8. describe——prescrible
根据上下文意义和语法，应为“医生为每一种症状开药”
9. an——the
此处的injection特指上文的a short of penicillin
10. 删除not
根据上下文意义，“患者会一直寻求，直到找到愿意为其打针或开药的医生为止”
