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

the rats are able to find more TB infections and, therefore, save

more lives.

Section B

Directions: In this section, you are going to read a passage with ten

statements attached to it. Each statement contains information given in

one of the paragraphs. Identify the paragraph from which the information

is derived. You may choose a paragraph more than once. Each paragraph is

marked with a letter. Answer the questions by marking the corresponding

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

U.S. 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 cal

l 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
