  F。 The brains of teenagers, but not adults, showed greater
activity in two regions associated with rewards when they were being
observed by same-age peers than when alone。 In other words, rewards
are more intense for teens when they are with peers, which motivates
them to pursue higher-risk experiences that might bring a big payoff
(such as the thrill of just making the light before it turns red)。
But Steinberg suspected this tendency could also have its advantages。
In his latest experiment, published online in August, Steinberg and
his colleagues used a computerized version of a card game called the
Iowa Gambling Task to investigate how the presence of peers affects the
way young people gather and apply information。

  All of which, combined with California’s reputation as the home of
technological 29 ,makes the place ideal for developing and testing
systems designed to monitor pollution in 30 。And that is just what
Aclima, a new firm in San Francisco, has been doing over the past few
months。 It has been trying out monitoring that are 31 to yield
minute-to-minute maps of 32 air pollution。 Such stations will also be
able to keep an eye on what is happening inside buildings, including
offices。

  Section C

  B) It aims to increase the yield of Spanish rice。

  A) Check the brain’s cognitive reserve。 C) Turn to a professional

  50。 D Staying active both physically and mentally。

  H。 Matthew D。 Lieberman, a social cognitive neuroscientist at the
University of California, Los Angeles, and author of the 2013 book
Social: Why Our Brains Are Wired to Connect, suspects that the human
brain is especially adept at learning socially salient information。 He
points to a classic 2004 study in which psychologists at Dartmouth
College and Harvard University used functional MRI to track brain
activity in 17 young men as they listened to descriptions of people
while concentrating on either socially relevant cues (for example,
trying to form an impression of a person based on the description) or
more socially neutral information (such as noting the order of details
in the description)。 The descriptions were the same in each
condition, but people could better remember these statements when given
a social motivation。

  A) Having regular physical and mental checkups。

  49。 What should people do when signs of serious memory loss show
up?

  A。 Parents of teenagers often view their children‘s friends with
something like suspicion。 They worry that the adolescent peer group has
the power to push its members into behavior that is foolish and even
dangerous。 Such wariness is well founded: statistics show, for
example, that a teenage driver with a same-age passenger in the car is
at higher risk of a fatal crash than an adolescent driving alone or with
an adult。

  Defense against memory loss is to try to prevent it by building up
your brain’s cognitive (认知的) reserve, Daffner says。

  49。 A Check the brain’s cognitive reserve。

  The battle is currently being waged on land, in greenhouses at the
University of Barcelona。 Scientists working under the banner “Project
Neurice” are seeking varieties of rice that can withstand the increasing
salinity without losing the absorbency that makes European rice ideal
for traditional Spanish and Italian dishes。

  Direction: There are 2 passages in this section。 Each passage is
followed by some questions or unfinished statement。 For each of them
there are four choice and our marked A),B),C) and D)。You should
decide on the best choice and nark the corresponding letter on Answer
sheet2 with a single line through the centre。

  D) Our whole brain starts shrinking。

  J。 If humans are generally geared to recall details about one
another, this pattern is probably even more powerful among teenagers
who are hyperattentive to social minutiae: who is in, who is out, who
likes whom, who is mad at whom。 Their penchant for social drama is
not—or not only—a way of distracting themselves from their schoolwork or
of driving adults crazy。 It is actually a neurological(神经的)
sensitivity, initiated by hormonal changes。 Evolutionarily speaking,
people in this age group are at a stage in which they can prepare to
find a mate and start their own family while separating from parents and
striking out on their own。 To do this successfully, their brain
prompts them to think and even obsess about others。

  C) Killing two bird with one stone。 D) Using one evil to combat

  D) Our whole brain starts shrinking。

  46。 Why does the author say that one needn’t be concerned about
memory slips?

  D。 Yet in the years following the publication of this study,
Steinberg began to believe that this interpretation did not capture the
whole picture。 As he and other researchers examined the question of why
teens were more apt to take risks in the company of other teenagers,
they came to suspect that a crowd‘s influence need not always be
negative。 Now some experts are proposing that we should take advantage
of the teen brain’s keen sensitivity to the presence of friends and
leverage it to improve education。

  C) Failure to remember the names of movies or actors。

  解析:找到关键词 memory slips。对应到文章第一段But if you have
memory slips, you probably needn’t worry。 There are pretty clear
differences between signs of dementia and age-related memory
loss。结合题干和原文可知,记忆的小错误并非全是痴呆的症状,而可能是由于年龄大。symptoms和signs为同义替换。顾答案选择A。

  Passage One

  B) Stop medications affecting memory。 D) Exercise to improve

  Questions 46 to 50 are based on the following passage。

  E) fierce M) supposed

  Forgetting the name of an actor in a favorite movie, for example,
is nothing to worry about。 But if you forget the plot of the movie or
don’t remember even seeing it, that’s far more concerning, Daffner
says。

  48。 A Totally forgetting how to do one’s daily routines。

  L。 And although anxious parents may not welcome the notion,
educators could turn adolescent recklessness to academic ends。 “Risk
taking in an educational context is a vital skill that enables progress
and creativity,” wrote Sarah-Jayne Blakemore, a cognitive
neuroscientist at University College London, in a review published last
year。 Yet, she noted, many young people are especially risk averse at
school—afraid that one low test score or mediocre grade could cost them
a spot at a selective university。 We should assure such students that
risk, and even peer pressure, can be a good thing—as long as it
happens in the classroom and not the car。

  50。 What is Dr Daffner’s advice for combating memory loss?

  44。 When we absorb information for the purpose of imparting it to

  50。 What is Dr Daffner’s advice for combating memory loss?

  B。 In a 2005 study, psychologist Laurence Steinberg of Temple
University and his co-author, psychologist Margo Gardner, then at
Temple, divided 306 people into three age groups: young adolescents,
with a mean age of 14; older adolescents, with a mean age of 19; and
adults, aged 24 and older。 Subjects played a computerized driving game
in which the player must avoid crashing into a wall that materializes,
without warning, on the roadway。 Steinberg and Gardner randomly
assigned some participants to play alone or with two same-age peers
looking on。

  After age 50, it’s quite common to have trouble remembering the
names of people, places and thing quickly, says Dr。 Kirk Daffner of
Brigham and Woman’s Hospital in Boston。

  A) Our interaction skills deteriorate。

  E。 In a 2011 study, Steinberg and his colleagues turned to
functional MRI (磁共振) to investigate how the presence of peers
affects the activity in the adolescent brain。 They scanned the brains
of 40 teens and adults who were playing a virtual driving game designed
to test whether players would brake at a yellow light or speed on
through the crossroad。
