B

One night last February, a seventeen-year-old Duffy drove home along a winding road, he saw a strange light thrown against the tree. “I knew it wasn’t the moon”, he said. “I drive this road all the time and I notice little things out of place.”

Duffy stopped his car and got out to examine. Below him far down in the deep valley lay a broken car with its headlights on. Thirty minutes earlier, a man had driven off the edge of the road, which has no guardrail. His car fell and rolled end over end, landing on its top more than two hundred feet below.

Duffy rushed to call for help, then returned and got down to reach the injured driver. Snow covered the valley and the temperature was below freezing. After struggling back up the cliff, Duffy took off his jacket and shirt and wrapped the injured man in time, along with the blankets from his car.

Life-saving deeds are starting to become usual action for Duffy, the oldest of seven children. When he was 12, he saved his ten-year-old brother from drowning. Two years ago, his three-year-old sister ate rat poison, and Duffy cleaned out her mouth, make her drink milk to protect her stomach and called doctors.

“We have tried to teach the children good values, and it looks like we have got some reward for it.” His father says.

46. The strange light came from ________.

A. The bright moon.          B. Duffy’s car.

C. The broken car in the valley   D. an unknown place

47. The phrase” landing on its top” means the car lay_________.

48. Duffy wrapped the man because_________.

A. he was badly injured    B. he had lost too much blood  

C. he had nothing on      D. it was too cold that day

49. From the above article, we can see Duffy has saved ________ at least.  

A. two     B. three     C. four      D. five

50. “We have tried to teach the children good values” may probably mean Duffy’s parents often tell their children_________.

A. to help people in danger         B. how to save people’s lives

C. to remember the value of the car     D. how to do business

A Brown University sleep researcher has some advice for people who run high schools: Don’t start classes so early in the morning. It may not be that the students who nod off at their desks are lazy. And it may not be that their parents have failed to enforce (確保) bedtime. Instead, it may be that biologically these sleepyhead students aren’t used to the early hour.

“Maybe these kids are being asked to rise at the wrong time for their bodies,” says Mary Carskadon, a professor looking at problem of adolescent  (青春期的) sleep at Brown’s School of Medicine.

Carskadon is trying to understand more about the effects of early school time in adolescents. And, at a more basic level. she and her team are trying to learn more about how the biological changes of adolescence affect sleep needs and patterns.

Carskadon says her work suggests that adolescents may need more sleep than they did at childhood, no less, as commonly thought.

Sleep patterns change during adolescence, as any parent of an adolescent can prove. Most adolescents prefer to stay up later at nigh and sleep later in the morning. But it’s not just a matter of choice –their bodies are going through a change of sleep patters.

All of this makes the transfer from middle school to high school—which may start one hour earlier in the morning  ---- all the more difficult , Carskadon says. With their increased need for sleep and their biological clocks set on the “sleep late, rise late” pattern, adolescent are up against difficulties when it conics to trying to be up by 5 or 6 a.m. for a 7:30 a.m. first hell. A short sleep on a desktop may be their body’s way of saying. “I need a timeout.”

Carskadon suggests that high schools should not start classes so early in the morning because ________.

A. it is really tough for parents to enforce bedtime

B. it is biologically difficult for students to rise early

C. students work so late at night that they can’t get up early

D. students are so lazy that they don’t like to go to school early

The underlined phrase “nod off” most probably means “ _______”.

A. turn around    B. agree with others  C. fall asleep  D. refuse to work

What might be a reason for the hard transfer from middle school to high school?

A. Adolescents depend more on their parents.

B. Adolescents have to choose their sleep patterns.

C. Adolescents sleep better than they did at childhood.

D. Adolescents need more sleep than they used to.

What is the test mainly about?

A. Adolescent heath care.      B. Problems in adolescent learning.

C. Adolescent sleep difficulties.   D. Changes in adolescent sleep needs and patterns.

Thousands of years ago people guessed the time of day by watching the sun.

Later，they found it was easier to tell the exact time by looking at the shadows.Thus， the sundial(日晷) was invented.

The sundial proved a useful timepiece  in sunny weather. However，another typc of  timepiece was necessary  for cloudy weather and nigh time.A sand glass was another  common measurer of time.Two glass bottles were connected by a very  small opening.  The top bottle was filled with sand，which dropped slowly into the botton one in a  certain period of time.Hour glasses were widely used then.Three—minute sand glasses  are still used in many homes to time the boiling of eggs.

The real ancestor of modern clocks was the water clock.In China ,an early  water clock was made up of several bowls. Water trickled(滴) from one bowl to another to keep the clock  going. Visitors to the  Beijing Palace Museum can still see the old  water clocks showing the time there.

In the Middle Ages a wateless clock was invented which  worked by means of  weights. To keep  the  weight  falling  at  the  same  speed，a  system  of wheels  was  invented. The pendulum(鐘擺) was  soon  developed  to control  the  speed of the  wheels. Thus the modern form of clock came into being.

9.Which of the following is the correct picturr of a sand glass?

            A.                       B.                       C.                     D.

10.Three minute sand glasses are still used in many homes         .

A.to boil eggs                           B.to measure the time of boiling eggs

C.to hold the boiled eggs                 D.to have eggs boiled

11.If you visit Beijing Palace Museum, you         .

A.will see the old water clocks broken

B.will find the time shown by the old water clocks is wrong

C.can find the old water clocks still telling the time there

D.will find the old water clocks have gone

12.In the Middle Ages the weight falling speed of a clock was kept by .

A.several bowls                         B.a system of wheels

C.a system of pendulum                  D.several springs
