TV Shows and Long Bus Trips Long bus rides are like televisions shows.They have a beginning,a middlle,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‘n’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 changed-new 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 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 arm rests-even with your hands crossed behind your head.The end comes just at the right time.There are just no more ways to sit.The writer feels long bus rides are like TV shows because______.

New Product Will Save lives
Drinking water that looks clean may still contain bugs（虫子）,which can cause illness.
A small company called Genera Technologies has produced a testing method in three
stages,which shows whether water is safe.The new test shows if water needs chemicals
added to it,to destroy anything harmful.It was invented by scientist Dr. Adrian Parton,
who started Genera five years ago.He and his employees have developed the test together
with a British water company.
Andy Headland,Genera's marketing director,recently presented the test at a
conference in the USA and forecast good American sales for it.Genera has already sold 11
of its tests at$42,500 a time in the UK and has a further four on order. It expects to sell
another 25 tests before the end of March.The company says it is the only test in the UK to
be approved by the government.
Genera was formed five years ago and until October last year had only five employees;
it now employs 14.Mr Headland believes that the company should make around$19 million
by the end of the year in the UK alone.Genera has increased the number of its employees recently.

Long Bus Ride
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'n 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 changed一new 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 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 you legs crossed,with your hands crossed behind your head. The end comes just at the right time.There are just no more ways to sit.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答案：B解析：第一段中介绍了乘客在坐长途车过程中所见的是广告牌。the commercials是“商业广告”的意思；billboard是“广告牌”的意思，即选项中的advertisements on the board。
全文主要介绍作者对乘车长途旅行的感受以及对长途旅行提出了一些意见。因此选择A。
在第一段中，作者说道：The commercials are unavoidable.They happen whether you want them or not．商业广告不可避免，无论你是否需要，它们都会出现。也说到： Only if you sleep...are you spared the unending cry of "You Need It! Buy It Now!”说明只有睡觉才能躲避广告。由此可以推断出作者不喜欢沿途的广告牌。
根据文章第一段第一句和第二句“乘坐长途车就如同看电视，有开端，有情节，也有结尾，每隔三四分钟插播商业广告”，判断B是正确的。
根据文章第二段第一句“旅程的开始是舒适并且有些兴奋的”和第三段第二句“你知道旅程将很快结束，就会产生一种期待和兴奋”，判断A正确。 -

The beginning of the ride is comfortable and somewhat exciting,even if you've traveled that way
before.Usually some things have changed一new 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 particu-
larly reckless 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?After a while,of course.the excitement dies

D:both traveling and watching TV are not exciting答案：B解析：文章第一段讲到乘长途汽车旅行就像看电视一样，汽车往前开，路两旁的广告不断地从窗旁掠过。
文章第一段说乘长途汽车旅行就像看电视一样，有开始、中间和结尾，期间还会时不时地伴有广告；紧接着描述了旅途中的这三部分及作者的感受，所以该文章讲述的是作者对乘长途汽车旅行的看法。
从文章第一段中“The commercials are unavoidable. They happen whether you want them or not.”及“Only if you sleep,which is equal to turning the television set off,are you spared the un-ending cry 'of 'You Need It! Buy It Now!'”可知，作者对这些广告的无奈。相反显示出作者更喜欢沿途没有广告牌。
由文章第一段的前两句“Long bus rides are like televisions shows. They have a beginning, middle, and an end一with commercials thrown in every three or four minutes.”可知，B项为正确答案。
