Long bus rides are like television shows. They have a beginning,a middle,and an end with commercials thrown in every three or four minutes. The commercials are unavoidable. They happen whether you want them or not. Every couple of minutes a billboard glides by outside the bus window. "Buy Super Clean Toothpaste.""Drink Good Wet Root Beer.""Fill up with Pacific Gas."Only if you sleep,which is equal to turning the television set off,are you spared the unending cry of "You Need It! Buy It Now!"

The beginning of the ride is comfortable and somewhat exciting,even if you’ve traveled that way before. Usually some things have changednew houses,new buildings,sometimes even a new road. The bus driver has a style of driving and it’s fun to try to figure it out the first hour or so. If the driver is particularly reckless (鲁莽的) or daring,the ride can be as thrilling as a suspense story. Will the driver pass the truck in time? Will the driver move into the right?or the left?hand lane? After a while,of course,the excitement dies down. Sleeping for a while helps pass the middle hours of the ride. Food always makes bus rides more interesting. But you’ve got to be careful of what kind of food you eat. Too much salty food can make you very thirsty between stops.

The end of the ride is somewhat like the beginning. You know it will soon be over and there’s a kind of expectation and excitement in that. The seat of course,has become harder as the hours have passed. By now you’ve sat with your legs crossed,with your hands in your lap,with your hands on the armrestseven with your hands crossed behind your head. The end comes just at no more ways to sit.

 

1.According to the passage,what do the passengers usually see when they are on a long bus trip?

A.Buses on the road.        B.Films on television.

C.Advertisements on the billboards.  D.Gas stations.

2.What is the purpose of this passage?

A.To give the writer’s opinion about long bus trips.

B.To persuade you to take a long bus trip.

C.To explain how bus trips and television shows differ.

D.To describe the billboards along the road.

3.The writer of this passage would probably favor .

A.bus drivers who aren’t reckless   B.driving alone

C.a television set on the bus     D.no billboards along the road

4.The writer feels long bus rides are like TV shows because .

A.the commercials both on TV shows and on billboards along the road are fun

B.they both have a beginning,a middle,and an end,with commercials in between

C.the drivers are always reckless on TV shows just as they are on buses

D.both traveling and watching TV are not exciting.

阅读下列短文,从所给的四个选项中,选出最佳答案

 Scientists had long dreamt of splitting the atom(原子) and let out some of its huge quantity of energyThey didn't find out how to do it until the 1940s

 Uranium is one of the matters whose atoms can be split fairly easilyA small particle(粒子) is added to an atom of uranium, which then breaks into two smaller atomsThe change has other resultsIt makes the uranium very hotIt also produces two or there free particles of the kind first addedThese free particles move around, splitting other uranium atoms, and so begins a chain reaction(链式反应), which produces more heat and more free particlesBoth the heat and the chain reaction are important

 A gas or a liquid is sent into the reactor(反应堆)to collect and carry away the heatIt is used to boil water, and the steam so produced drives the machinery which produces electricityThe chain reaction allows the process(过程) to continueThe reaction, which could be very rapid, is slowed down by a certain matter, which surrounds the fuel

 Today, many people are wondering how long the world's store of coal and oil will lastBoth these fuels, like uranium, are producers of heat energyIs atomic energy the answer to the world's energy problem?

(1) Which of the following words can take the place of the underlined wordsplitting?

[  ]

Ajoining    Bchoosing

Cbreaking   Dheating

(2) What will never happen when a small particle is added to an atom of uranium?

[  ]

ATwo more atoms will appear

BThe atom will split in two and let out energy

CMore free particles will be produced

DThe uranium will become very hot

(3) Chain reactionmeans______

[  ]

Afree particles produced in the reaction will split other atoms, which in turn will produce more free particles

Bfree particles will split more atoms after splitting some atoms

Catoms split by free particles will continue to split

Dreaction can go on and on with the help of a chain of particles

(4) Which of the following orders shows rightly how a nuclear (原子能的) power plant works?

[  ]

aHeat is made to boil water

bThe machinery produces electricity

cThe chain reaction produces heat

dHeat is collected and carried away by a gas or a liquid

eSteam so produced drives the machinery

Ad-c-e-b-a   Bc-d-a-e-b

Cb-d-e-a-c   Dc-a-d-b-e

(5) What fact does this passage lead you to believe?

[  ]

AMany people wonder whether the world's store of coal and oil will last long

BCoal, oil and uranium are fuels, which can produce heat

CThe world's store of coal and oil will last a very long time

DAtomic energy has given people hope to solve the world's energy problem
