  Methods of studying vary; what works   1   for some students doesn’t work at all for others.The only thing you can do is experiment   2   you find a system that does work for you.But two things are sure:  3   else can do your studying for you, and unless you do find a system that works, you won’t although college.Meantime, there are a few rules that   4   for everybody.The hint is “don’t get   5  ”.

  The problem of studying,   6   enough to start with, becomes almost   7   when you are trying to do   8   in one weekend.  9   the fastest readers have trouble   10   that.And if you are behind in written work that must be   11  , the teacher who accepts it   12   late will probably not give you good credit.Perhaps he may not accept it   13  .Getting behind in one class because you are spending so much time on another is really no   14  .Feeling pretty virtuous about the seven hours you spend on chemistry won’ t   15   one bit if the history teacher pops a quiz.And many freshmen do get into trouble by spending too much time on one class at the   16   of the others, either because they like one class much better or ?because they find it so much harder that they think, they should   17   all their time to it.  18   the reason, going the whole work for one class and neglecting the rest of them is a mistake, if you face this   19  , begin with the shortest and easiest   20  .Get them out of the way and then go to the more difficult, time consuming work.

  A new report says only about half of all students in the main school systems of America’s largest cities finish high school.The report notes higher rates of graduation-over 70%-in areas surrounding the cities.Researchers studied high school graduation rates from the 2003, 2004 school year.They also identified the nation’s fifty largest cities.The largest, New York City, had a population of more than eight million.The smallest city was Wichita, Kansas.It had about three hundred and sixty thousand people.

  Researchers used a system of measurement called the cumulative promotion index to find graduation rates.School officials in many of the cities studied said the resulting numbers were too low.That is because different areas use different methods to find graduation rates.Critics say many methods do not give a true picture of the number of students who leave high school before finishing.

  Other studies have put the national graduation rate at about 70%.But experts agree that too many students are not completing high school.They estimate the number at more than one million each year.The report was prepared for America’s Promise Alliance.The private group aims to help children receive services they need to succeed.

  General Colin Powell was chairman of America’s Promise Alliance when it was formed in 1997.He attended the press conference Tuesday where the report was released.He said studies have shown that the US must do more to educate the leaders and work force of the future.

  Secretary of Education Margaret Spellings also spoke.She said the government will propose that states use the same methods when reporting graduation rates.Alliance officials also announced the start of a nationwide campaign to improve graduation rates.It is to include a series of meetings to be held in every state over the next two years.The meetings will bring together elected leaders, business owners, students, parents and education officials.They will develop plans to increase the number of Americans who finish high school.

[  ]

A.

too many Americans do not finish high school

B.

different methods to find graduation rates

C.

services American children need to receive

D.

the increase of the number of Americans who finish their high school

[  ]

A.

there are 8,360,000 people in the US’ fifty largest cities

B.

Wichita in Kansas is the smallest city in the US

C.

50% of the people in the US don’t finish their high school education

D.

high school graduation rates in or near the biggest cities are higher

(3)

The underlined word “picture” probably can be replaced by “________”.

[  ]

A.

situation

B.

scene

C.

image

D.

B.

the government will stop using the cumulative promotion index to find graduation rates

  The First Americans

  There was a time long ago when a land bridge connected Asia and North America.The first settlers in North America crossed this land bridge from what is now Siberia to Alaska.The people who made this initial crossing were probably following the animals they used for food.

  Eventually, the oceans rose and the land bridge between the continents disappeared.The settlers, who I shall call the "First Americans", could not return to their homeland.  1  

  For the next few thousand years, the First Americans migrated south and east throughout North and South America.They made the journey all the way from Alaska to the southern! tip of South America, a distance of more than 10,000 miles.  2  

  In the far north, above the Arctic Circle, the First Americans became hunters of the ocean.  3   In the brief summer, they gathered berries and other plants.In the winter, they stayed in lodges much of the time preparing for the next summer.It was a hard life, but they learned to survive in these harsh conditions.

  Farther south, in what is now Arizona, Utah, Colorado, and New Mexico, the First Americans became cliff dwellers(悬崖居民).They began by living in caves that already existed in the cliffs.  4   The dwellings they constructed in many ways resembled today's apartment buildings.

    5   They built a system of dams and canals so they could store and use water almost any time of the year.They were so successful that they could raise fruits and vegetables that were not found naturally in the desert.

  In Mexico and South America, the First Americans founded civilizations that were among the greatest in the world.They built huge pyramids, lived in fabulous cities, and made great advances in science and mathematics long before the Europeans arrived.

A.They also discovered foods like corn and potatoes.

B.Along the way, they established many different civilizations.

C.The First Americans of the Southwest learned to irrigate the desert.

D.They would have to survive in the New World, they had discovered.

E.They built boats of animal skins and hunted or fished for their food.

F.People living near each other tended to share similar environments and customs.

G.They discovered how to add to the caves by building structures of wood and stone.
