Section A

Directions:In this section,there is a passage with ten blanks.You are required to select one word for each blank from a list of choices given in a word bank following the passage.Read the passage through carefully before making your choices.Each choice in the bank is identified by a letter.Please mark the corresponding letter for each item on Answer Sheet 2 with a single line through the centre.You may not use any of the words in the bank more than once.

A rat or pigeon might not be the obvious choice to tend to someone who is sick,but these creatures have some 26 skills that could help the treatment of human diseases.

Pigeons are often seen as dirty birds and an urban 27,but they are just the latest in a long line of animals that have been found to have abilities to help humans.Despite having a brain no bigger than the 28 of your index finger,pigeons have a very impressive 29__memory.Recently it was shown that they could be trained to be as accurate as humans at detecting breast cancer in images.

Rats are often 30 with spreading disease rather than 31 it,but this long-tailed animal is highly 32.Inside a rat's nose are up to 1,000 different types of olfactory receptors(嗅觉感受器),whereas humans only have 100 to 200 types.This gives rats the ability to detect__33 smells.As a result,some rats are being put to work to detect TB(肺结核).When the rats detect the smell,they stop and rub their legs to 34 a sample is infected.

Traditionally,a hundred samples would take lab technicians more than two days to 35,but for a rat it takes less than 20 minutes.This rat detection method doesn't rely on specialist equipment.It is also more accurate—the rats are able to find more TB infections and,therefore,save more lives.

Do In-Class Exams Make Students Study Harder

Research suggests they may study more broadly for the unexpected rather than search for answers.

[A]I have always been a poor test-taker.So it may seem rather strange that I have returned to college to finish the degree I left undone some four decades ago.I am making my way through Columbia University,surrounded by students who quickly supply the verbal answer while I am still processing the question.

[B]Since there is no way for me to avoid exams,I am currently questioning what kind are the most taxing and ultimately beneficial.I have already sweated through numerous in-class midterms and finals,and now I have a professor who issues take-home ones.I was excited when I learned this,figuring I had a full week to do the research,read the texts,and write it all up.In fact,I was still rewriting my midterm the morning it was due.To say I had lost the thread is putting it mildly.

[C]As I was suffering through my week of anxiety,overthinking the material and guessing my grasp of it,I did some of my own polling among students and professors.David Eisenbach,who teaches a popular class on.presidents at Columbia,prefers the in-class variety.He believes students ultimately learn more and encourages them to form study groups.“That way they socialize over history outside the class,which wouldn’t happen without the pressure of an in-class exam,”he explained,“Furthermore,in-class exams force students to learn how to perform under pressure,and essential work skill.”

[D]He also says there is less chance of cheating with the in-class variety.In 2012,125 students at Harvard were caught up in a scandal when it was discovered they had cheated on a take-home exam for a class entitled“Introduction To Congress.”Some colleges have what they call an“honor code,”though if you are smart enough to get into these schools,you are either smart enough to get around any codes or hopefully,too ethical to consider doing so.As I sat blocked and clueless for two solid days,I momentarily wondered if I couldn’t just call an expert on the subject matter which I was tackling,or someone who took the class previously,to get me going.

[E]Following the Harvard scandal,Mary Miller,the former dean of students at Yale,made an impassioned appeal to her school’s professors to refrain from take-hone exams.“Students risk health and well being,as well as performance in other end-of-term work,when faculty offers take-home exams without clear,time-limited boundaries,”she told me.“Research now shows that regular quizzes,short essays,and other assignments over the course of a term better enhance learning and retention.”

[F]Most college professors agree the kind of exam they choose largely depends on the subject.A quantitative-based one,for example,is unlikely to be sent home,where one could ask their older brothers and sisters to help.Vocational-type classes,such as computer science or journalism,on the other hand,are often more research-oriented and lend themselves to take-home testing.Chris Koch,who teaches“History of Broadcast Journalism”at Montgomery Community College in Rockville,Maryland,points out that reporting is about investigation rather than the memorization of minute details.“In my field,it’s not what you know—it’s what you know how to find out,”says Koch.“There is way too much information,and more coming all the time,for anyone to remember.I want my students to search out the answers to questions by using all the resources available to them.
