A Memory Drug？
It'sdifficult to imagine many things that people would
welcome more than a memory-enhancing drug.____1____
Furthermore，such a drug could help people remember past
experiences more clearly and help us acquire new information
more easily for school and at work.As scientists learn more
about memory，we are closing in on this tantalizing goal.1
Some of the most exciting evidence comes from research
that has built on earlier findings linking LTP2 and memory to
identify a gene that improves memory in mice.____2____ Mice
bred to have extra copies of this gene showed more activity
in their NMDA receptors，more LTP，and improved performance
on several different memory tasks—learning a spatial layout3，recognizing familiar objects，and recalling a fear-inducing
shock.
If these basic insights about genes，LTP，and the
synaptic basis of memory can be translated to people—and
that remains to be seen—they could pave the way for memory-enhancing treatments.____3____ As exciting as this may sound，it also raises troubling issues.Consider the potential
educational implications of memory-enhancing drugs.If memory
enhancers were available，children who used them might be
able to acquire and retain extraordinary amounts of
information，allowing them to progress far more rapidly in
school than they could otherwise.How well could the brain
handle such an onslaught of information？ What happens to
children who don't have access to the latest memory enhancers？ Are they left behind in school—and as a result handicapped
later in life？
____4____ Imagine that you are applying for a job that
requires a good memory，such as a manager at a technology
company or a sales position that requires remembering
customers' names as well as the attributes of different
products and services.Would you take a memory-enhancing drug
to increase your chances of landing the position？ Would
people who felt uncomfortable taking such a drug find
themselves cut out of lucrative career opportunities？
Memory drugs might also help take the sting out of
disturbing memories that we wish we could forget but can't.4
The 2004 hit movie Eternal Sunshine of the Spotless Mind told
the story of a young man seeking just such freedom from the
painful memories of a romantic breakup.As you will see in the
section on persistence later in the chapter，emotionally
arousing events often create intrusive memories，and
researchers have already muted emotional memories with drugs
that block the action of key hormones.Should emergency
workers who must confront horrifying accident scenes that can
burden them with persisting memories be provided with such
drugs？ Should such drugs be given to rape victims who can't
forget the trauma？ Memory drugs might provide some relief to
such individuals.But could they also interfere with an
individual's ability to assimilate and come to terms with a
difficult experience？5 ____5____
练习：
A.Like steroids for bulking up the muscles，these drugs
would bulk up memory. B.A memory enhancer could help eliminate forgetting
associated with aging and disease.
C.What are the potential implications of memory-enhancing
drugs for the workplace？
D.We may find ourselves struggling with these kinds of
questions in the not-too-distant future.
E.There is a pill that you could take every day to allow
you to remember everything.
F.The gene makes a protein that assists the NMDA2
receptor，which plays an important role in long-term memory
by helping to initiate LTP.
答案与题解：
1.B依据上一句的“很难想象一种提升人们记忆力的药会受到人们吹捧”；下面应该对这个现象做出解释，即这种药物有什么疗效；而后一句的Furthermore这个指示词起到了递进的作用，进一步说明这种药物的益处。More than ：非常，极其，十分
2.F前一句的关键词是gene、LTP和mice，它讲的是有些令人兴奋的证据是从研究中得出的；该研究基于早期连接LTP和记忆的发现，该结果确定了提髙老鼠记忆的基因；而后一句进一步阐述这个发现，开头的mice能够是一个连接词。
3.A前一句讲：如果这种结果用于人类的话，人们就有可能把提升人的记忆力用于临床。这个句讲：就像类固醇用于提髙人的肌肉水平，这种药物也能够提升人的记忆力。
4.C一般情况下，每一段的第一句都是本段的主题句。而该句是一个问句：这种提升记忆力的药物用于职场有什么潜在的启示呢？紧接着本段其余几句都提出关于这种药物是否会对职场的提升有什么影响的问题。
5.D本句是全文的最后一句。应该是总结性的。鉴于前面都列举了这种提升记忆力的药所面临的一系列问题，所以，我们在不久的将来要面临这些问题。

Good Writing
Like fine food,good writing is something we approach with
pleasure and enjoy from the first taste to the last.(46)
Quite the contrary,just as the cook has to undergo an
intensive training,mastering the skills of his trade,the
writer must sit at his desk and devote long hours to
achieving a style in his writing,whatever its purpose--school
work,matters of business,or purely social communication.(47)
There are still some remote places in the world where you
might find someone to do your business or social writing for
you,for a fee.There are a few managers who are lucky enough
to have the service of that rare kind of secretary who can
take care of all sorts of letter writing with no more than a
quick note to work from.(48)
We have to write school papers,business papers or home

Can you hear This?
When something creates a sound wave in a room or an
auditorium, listeners hear the sound wave directly from the
source. They also hear the reflections as the sound bounces
off the walls, floor, and ceiling. These are called the
reflected wave or reverberant(反射的)sound, which can be
heard even after the sound is no longer coming from the
source.
The reverberation time of an auditorium is determined by
the volume or interior size of the auditorium. It is also
determined by how well or how poorly the walls, ceiling,
floor, and contents of the room (including the people) absorb
sound. There is no ideal reverberation time. Because each use
of an auditorium calls for different reverberation. Speech
needs to be understood clearly： therefore rooms used for
talking must have a short reverberation time. The full-sound
