The art of living is to know when to hold fast and when to let

第三部分閱讀理解
A
One day,an expert in time management was speaking to a group of
students and ,to drive home a point,used an illustration those students will
never forget.
Standing before the group of overachievers(成績(jī)超過預(yù)料的學(xué)生),he said,"Ok,time for
a quiz."He pulled out out a one-gallon,wide -mouth jar and set it on the
table in front of him.He also produced about a dozen fist-sized rorocks and
carefully placed them,one at a time,into the jar.When no more rocks would fit
inside,he asked,"Is this jar full?"
Everyone in the class yelled,"Yes"The expert reached under
the table and pulled out a bucket of gravel.He dumped some gravel in and shook
the jar,causing pieces of gravel to work themselves down into the spaces
between the big rocks.He then asked again,"Is this jar full?"
"Probably not."one of them answered."Good."He
replied.He reached under the table and brought out a bucket of sand.He started
dumping the sand in the jar and it went into all of the spaces left between the
rocks and the gravel.Onece more he asked the question,"Is this jar full?”
“No!"the class
shouted."Good."He replied.He grabbed a pitcher of water and began to
pour it in until the jar was filled to the brim.Then he looked at the class and
asked,"What is the point of this illustration?"One eager student
raised his hand and said,’“No matter how full your schedule is,if you try really hard you can
always fit some more things in it!"
"_______,"the expert replied.“The truth this illustrtion teaches
us if you don't put the big rocks in first ,you'll never get them in at
all.What are the "big rocks"in your life?Time with your loved
ones,your education,your dreams,a worthy cause,or teaching others?Remember to
put these big rocks in first or you'llnever get them in at all."
56Which group of words means containers?
A.jar,gravel,bucket
B.jar,illustration,gravel
C.jar,bucket,pitcher D.jar,brim,pitcher
57What replies would the expert probably
make in the last paragraph
A.I beg you pardon B.Good
idea
C.That's not the point D.You got it
58Choose the order that the expert put
things in the jar.
A.rocks--->sand---->gravel---->water
B.rocks--->gravel--->sand---->water
C.gravel---->water----.>sand---->rocks
D.gravel--->sand--->water--->rocks
59What's the expert's conclusion?
A.We must think of all kinds of ways to solve our problems
BWe must
try really hard to fit more small things in our life
C.We must know what big rocks are in our
life and then put them in first
D.We must know things like gravel,sand and
water are not important at all

For many students in Beijing,Mr.Obama symbolizes all that is
possible in the United States.He's a popular winner here,seen as a self-made
man who has made it to the top.
"I think he is very charming,and a president who can create a
new era(時(shí)代),"said
ZhangWei,a university student."I like him very much and most of my friends
do too."
Ni Weibo,another university student,agrees."Sino-U.S. Relations
still need more cooperation,"she said."I think he will help take it
to a new era."
China's President Hu Jintao congratulated Mr. Obama within hours of
his victory,saying he hoped bilateral ties could be made stronger.
Political analysts(分析家)here say China will be looking for the incoming president to avoid
contentious issues such as Taiwan's independence,human rights and Tibet.
Instead,they say Beijing would like Mr Obama to focus on solving the
global economic crisis(危機(jī)),and to help China's slowing economy by opening up U.S. Markets.
But trade relations might be a sticking point,says Renmin
University's Professor of International Studies,Shi Yinhong.
He warns,"There is a possibility that President Obama will take
some protectionist measures which China will not accept,then trade disputes could
develop to a degree that we have not seen ever before."
Despite making the headlines,Mr.Obama faces some tough challenges in
managing the U.S. Relationship with China.
China is now a stronger and more confident country than the China
his predecessors(前任)dealt
with.And in this time of economic uncertainty,analysts say it's a country with
wich Mr.Obama will want to maintain a good relationship.
60Many students in Beijing
expect that Mr.Obama
can________.
A.made everything possible
B.further strengthen Sino-U.S.relations
C.become a self-made man D.try to help China into a new era
61According to some analysts,which of the
following is what China would like Mr.Obama to do?
A.Facing some tough challenges
B.Taking some protectionist measures
C.Making Sino-U.S.bilateral ties
stronger
D.Opening up markets to speed China's
economy
62The underlined word
"dispute"means"______"
A.serious disagreemen
B.severe measures
C.tough crisis D.confusing issues
63As mentioned in the text,Mr. Obama will
want to maintain a good relationship with China because________.
A.China is now a stronger and more confident country
B.he has tough challenges in managing the
relationship with China
C.he wants to avoid issues like Taiwan's
independence,human rights and Tibet
D.Mr.Hu Jintao congratulated Mr.Obama
within hours of his victory

It used to be that shopping was a fairly simple activity---you went
to the supermarket,picked up what you need,paid for it and left.But in recent
years it's become a lot more complicated.Supermakets in the UK now sell much
more than food :you can get your insurance there ,pay bills and a variety of
other services.In many ways they've become a one-stop shop for lots of life's
daily chores.
You can also get "rewards"----join up and get a
"loyalty card"and every time you shop you'll get points and
discounts.And just when you thought supermakets couldn't offer anything
else,they turned into mini-banks,offering you cash when you shop .Go into any
UK supermarket,pay for your shopping,and you're more than likely to be asked if
you want "any cashback with that?”
This is only offered if you pay by debit card(簽證卡).Effectively,if you buy ζ30 worth of shopping,you can pay ζ50 with your debit card and the
supermarket will give you your shopping plus,ζ20 in cash from the till(收款機(jī))。
Originally introduced by the supermaket gaint Tesco,it eases busy
shoppers' lives by cutting out an extra visit to the bank.Of curse, they didn't
just introduce this for the customer's benefit---shops also benifit by having
less cash in-house,and by paying less in fess for taking this cash to their
local bank.
In recent years the phrase
"cashback!"has also been
observed as an exclamation of joy or satisfaction,as in:"It's three drinks
for the price of two in the pub tonight.Cashback!"
64Supermakets in the UK now are different
from what it used be because_______
A.they will
ask shoppers to pay only by cashback
B.they don't sell food and other daily
necessitites
C.they have made shopping much more
complicated
D.they provide a veriety of other services
besides shopping
65.The cash
you get when you shop in supermakets comes from the______.
A.points and
discounts B.built-in mini-banks
C.supermaket giant Tesco D.extra visits to the bank
66Who will benefit
from"Cashback!"?
A.Only busy
shoppers B.Only supermakets
C.The local banks D.Both shoppers and shops
67What may be the best title for the text?
A.UK
Supermarkets B.Cashback! C.One-stop Shops D.The Best Services

The intelligence of
the dog is among the highest of all the animals,maybe higher than we give him
credit for.Although his brain is only half as large as ours,he is certainly the
most intelligent of domestic animals.
A scientist in Brazil has proven dogs can count.He used a technique
which also proved that 5 month old infants can count:
"He placed treats in a bowl,hid it with a screen and let the
animals watch as he removed or added some.The dogs studied the contents longer
when the screen was taken away if a trick had been played leaving more or less
treats than expected .He tasted 11 mongrels(雜種狗)and found they paid little attention when one plus one resulted in
two treats.But they looked more closely when one plus one left three."
Memory is an important component of intelligence.The dog's memory
for scents is extraordinary.His visual memory is only fair,but his memory for
sounds is very good,since he can remember and identify familiar voices even
after an absence of many years .While he builds up a large store of
identifiable sounds without the slightest effort,remembering different words
requires more concentration.
The dog's capacity for learning is more a matter of memory than of
true understanding.He will remember the sequence of cause and effect in his
actions,but he is unable to draw broad conclusions from his experience.The
greater the variety of experiences and contact with others they have,the
quicher they learn,and the more they retain.
Dogs are bound by nature to remain intellectually inferior to (劣于)man,but we owe them a chance
todevelop their native intelligence by training,teaching,and working with them
as much and as often as we can.
