  If you want your land to keep fertile(肥沃的),you must try to stop soil from being carried away by water or winds. When soil is taken away by flowing water or blowing winds, we call it soil erosion(侵蚀).Ways have been found to stop soil erosion, and this is known as soil conservation(保存). One way of stopping soil erosion is to grow small plants such as grasses. These plants are referred to as cover crops, whose roots hold the soil tightly together. The rain water cannot wash away the soil. When trees and tall bushes are planted at the edges of an open filed, soil erosion by strong winds cannot take place. The trees and bushes, which act as a very big and firm wall, protect the open land from the winds. The way to stop soil erosion on slopes is to build terraces on the slope of hillside and mountainside. When the slope of a hillside is cut into“steps”,water carrying soil cannot run straight down the terraces, which are used to show down the speed of the flowing water containing much soil in it. In this way most of the soil in the water is left behind on the terraces, much soil in it. In this way most of the soil in the water is left behind on the terraces.

(1)What takes place in soil erosion?

[  ]

A. Flood happens to the fertile land.

B. A large quantity of the earth wears away gradually.

C. Terraces are built on the slope of a hillside or mountainside.

D. Plants are grown to protect the open land.

(2)“cover crops”in this passage means ________ .

[  ]

A. grass roots

B. trees and bushes

C. plant lives of an area

D. covering plants that produce grain or vegetables

(3)Trees and tall bushes are planted around an open field _______ .

[  ]

A. because their roots hold soil tightly

B. to stop soil from being blown away by winds

C. because soil erosion causes terrible damage to crops

D. to keep the ecological balance

答案:B;C;B

  In the 1970s, with ever-increasing international travel and tourism, the United States Department of Transportation decided to design a set of symbols(符号)for airports, stations, and public facilities(设施). The aim was to design symbols that would be clear to people in a hurry and to those who can not read English. Therefore, the set of symbols shown below was designed. Then the designers planned an experiment with an international sample(抽样调查) of 8-year-old children from Sweden. Japan, France, Canada, and Britain. The purpose of the experiment was to determine how clear the symbols would be to the children, who were not experienced international travelers.

  The children were shown the set of sample symbols, and were then asked to explain to the experimenters what the symbols meant. The researchers thought that if the international sample of children could understand them, the grown-up travelers would probably also recognize their meanings. The following graph(图表) shows the percentages of correctly explained symbols.

  The experiments discovered that most of the children easily understand the telephone receiver and cigarette symbols. However, there were some interesting differences in their answers to the other four symbols. The Japanese children most easily understood the symbol standing for“coffee shop”. The experimenters thought that this fact showed children in Japan are more familiar with such shops than children in Sweden and Canada. The Japanese, French, and Canadian children all equally recognized the idea of“information”showed by the question mark.

  Interestingly, the French and Canadian children understood the symbol referring to“campground(露营地)”better than the other children. Again, the researchers thought that recognition of a symbol shows how common the activity is in a country.

  One particularly difficult symbol was that of the umbrella and glove used for“lost and found”, which was correctly explained by less than 50% of the children in four of the five countries. On the basis(基础) of this finding, the experimenters decided to add a question mark to make this symbol easier to understand.

1.Which of the following shows the correct meaning of(X), (Y), and (Z) in the graph above?

[  ]

A.Campground, Coffee Shop, Lost and Found.

B.Lost and Found, Campground, Coffee Shop.

C.Coffee shop, Lost and Found, Campground.

D.Telephone, No smoking, Information.

2.If we compare the Japanese and French children's understanding of the question mark and cigarette symbols, then we can find a difference of _____ between these symbols.

[  ]

A.0%   B.10%

C.80%   D.90%

3.The _____ symbol was the most difficult for the Japanese children to understand.

[  ]

A.cup   B.question mark

C.tent   D.umbrella and glove

4.Which of the following statements is TRUE?

[  ]

A.The experimenters thought Japanese children drink coffee.

B.The most difficult symbol was changed to make it clearer.

C.The question mark symbol is the least difficult in all five countries.

D.The researchers thought children would know as much as grown-ups.

Old-Fashioned Play-For Pay

  Kids!Come have a ball!Or 60,000 of them!There’s a new type of business franchise that is appearing in shopping malls and neighborhoods across America offering pay-per-use indoor playgrounds ,which feature toys ,games ,supervised fun and a workout that doesn’t break the family bank.

  As public playgrounds grow increasingly worn and dirty, the for-profit centers offer clean, safe supervised activity as well as a variety of challenging exercises to develop youngsters’ physical fitness, usually for a fee of around 5$ an hour.“Playgrounds are dirty ,not supervised,” says Dick Guggenheimer ,owner of the two-month-old Discovery Zone in Yonkers, N.Y., part of Kansas City-based chain, “We are indoors; we are padded(铺上软垫);parents can feel their child is safe”.

  In order to satisfy the need of two-earner families ,the new franchise stayed open in the evenings ,long after traditional public playgrounds have grown dark and unusable.However these new playgrounds are not meant to be day-care centers.Parents are expected go stay and play with their kids rather than drop them off.But several also provide high-tech baby-sitting services.At some of the Discovery Zones, parents can register their children in special supervised programs, then leave them and slip away for a couple of hours to enjoy a movie or dinner.If there is a problem ,Mom and Dad are called.

  The most fun of all, though, is getting to do what parents used to do in the days before two-earner families and two-hour commutes; play with their kids.That ,at least ,is old-fashioned, even at per-hour rates.

A.

A new type of business franchise for kids.

(2)

According to the article, which of the following is true to the new playground?

[  ]

A.

The cost is high for a family.

B.

It stayed open in the evening just as traditional playgrounds.

C.

It doesn’t allow parents to leave their kids.

D.

It’s a place where parents can play together with their kids.

(3)

What does the writer mean by saying “old-fashioned”?

[  ]

A.

The so-called new playground is outdated.

B.

The new playground is also enjoyed by old people.

C.

The new playground is actually enjoyed by parents.

D.

The new playground offers a fashion which is poplar in the past.

     As a young boy, I sometimes traveled the country roads with my dad. He was a rural mill carrier, and
on Saturdays he would ask me to go with him. Driving through the countryside was always an adventure:
There were animals to see, people to visit, and chocolate cookies if you knew where to stop, and Dad
did.
     In the spring, Dad delivered boxes full of baby chickens, and when 1 was a boy it was such a fun to
stick y our finger 'through one of the holes of the boxes and let the baby birds peck on your fingers.
     On Dad' s final day of work, it took him well into the evening to complete his rounds because at least
one member from each family was waiting at their mailbox to thank him for his friendship and his years
of service. "Two hundred and nineteen mailboxes on my route." he used to say, "and a story at every
one. " One lady had no mailbox, so Dad took the mail in to her every day because she was nearly blind.
Once inside, he read her mail and helped her pay her bills.
     Mailboxes were sometimes used for things other than mail. One note left in a mailbox read. "Nat, take
these eggs to Marian; she's baking a cake and doesn't have any eggs. " Mailboxes might be buried in the
snow, or broken, or lying on the groom:. bat the mail was always delivered On cold days Dad might find
one of his customers waiting for him with a cup of hot chocolate. A young wrote letters but had no
stamps, so she left a few button on the envelope in the mailbox; Dad paid for the stamps. One
businessman used to leave large amounts of cash in his mailbox for Dad to take to the bank. Once, the
amount came to 8 32,000.
     A dozen years ago, when I traveled back to my hometown on the sad occasion of Dad's death,  the
mailboxes along the way reminded me of some of his stories. I thought I knew them all, but that wasn't
the case.
     As I drove home, I noticed two lamp poles, one on each side of the street. When my dad was
around, those poles supported wooden boxes about four feet off the ground. One box was painted green
and the other was red, and each had a long narrow hole at the top with white lettering: SANTA CLAUS, NORTH POLE. For years children had dropped letters to Santa through those holes.
     I made a turn at the comer and drove past the post office and across the railroad tracks to our house. Mom and I were sitting at the kitchen table when I heard footsteps. There, at the door, stood Frank
Townsend, Dad's postmaster and great friend for many years. So we all sat down at the table and began
to tell stories.
     At one point Frank looked at me with tears in his eyes. " What are we going to do about the letters
this Christmas?" he asked.
     "The letters?"
     'I guess you never knew. "
     "Knew what?"
     " Remember, when you were a kid and you used to put your letters to Santa in those green and red
boxes on Main Street? It was your dad who answered all those letters every year. "
     I just sat there with tears in my eyes. It wasn't hard for me to imagine Dad sitting at the old table in
our basement reading those letters and answering each one. I have since spoken with several of the
people who received Christmas letters during their childhood, and they told me how amazed they were
that Santa had known so much about their homes and families.
     For me, just knowing that story about my father was the gift of a lifetime.
