16.People in several American states may be surprised to see cars on city streets without a driver.Experimental driverless vehicles now are legal in Florida,Nevada and California.They are pointing the way to a future that is not far down the road.The high-tech company Google has a number of self-driving cars,which had covered 480,000 kilometers by August.Volvo is among the companies doing road tests and says it plans to sell driverless cars by 2020.
     In September,California Governor Jerry Brown signed an act to allow autonomous vehicles on the roads of his state."Today we're looking at science fiction becoming tomorrow's reality-the driverless car."The technology for these cars includes cameras,radar and motion sensors.The systems have been improved through competitions sponsored by the U.S.government agency DARPA.Engineer Richard Mason of the Rand Corporation helped design driverless vehicles for DARPA challenge races.
     Cars have become much more fuel-efficient,and new electronic features are'making Hondas safer,said Angie Nucci of Honda America."A camera on the passenger-side mirror actually engaged on your guiding screen so you can safely change lanes."Other safety features include warning systems on the front and the sides of the cars.These systems help drivers,but don't replace them.Curator Leslie Kendall of the Petersen Automotive Museum said autonomous cars will make the high ways safer.
"By taking out drivers,you also remove most risks of an accident,"Kendall said.He said consumers,however,may be unwilling to lose control."It may take them time to come to realize that the technology is indeed reliable,but it will have to prove itself first."
     Mason said the technology already works and the biggest challenge now is getting down the cost for driverless vehicles from hundreds of thousands of dollars to something more affordable.He said this will happen as the technology is improved.
61.What can we learn from Paragraph l?D
A.Driverless vehicles are now legal in the whole USA.
B.Volvo will be the first to sell driverless cars.
C.Driverless cars are pointing us a faraway future.
D.Google's self-driving cars have covered a long distance.

6.When a big boat,like a cruise ship,goes through the ocean,it often creates waves.This happens when the large engines on the back of the cruise ship cause the water on the ocean's surface move up and down violently.These waves move out from the boat in both directions.If you are captaining a smaller boat,you'd better steer clear of a ship's wake,so that your boat is not surfing on the waves,causing it to overturn
A wave is a pattern of motion.When you look at a wave,it may appear as simply water moving across the surface of the ocean.In fact,this is false.The water is actually not moving in the same direction as the wave.While the wave itself--the pattern of motion-is moving across the surface of the ocean,the water is actually moving in a circular motion,which brings the water molecules back to their original position.The water merely gives the appearance of moving forward.
If this is confusing,think of the kind of wave you do at a baseball stadium.Viewed from a distance,the wave is clearly moving across the stadium.But the thing that makes up the wave-the people-are not moving across the stadium,they're just moving up and down in their seats.This is just like the water in an ocean wave.A lot of water is moving up and down,which gives water the appearance of moving along with the wave.
Surfers pay a lot of attention to waves.If you're not in an area where the waves are suitable for surfing,then you can't surf.Usually,surfers gather in areas known for big waves-waves that rise high off the ocean's surface.If the wave is bigger,then the surfer is often able to surf for longer distances and perform more tricks.The height of a wave is known as its amplitude.If you could make a wave freeze,then you could measure the wave's amplitude by running a tape measure from the ocean's surface to the very peak of the wave.
All waves can be measured using amplitude and wavelength.While the waves created by a boat have very small amplitude-sometimes as small as a few centimeters-the wavelength can be very short,as lots of waves are being generated.By contrast,a tsunami has very high amplitude,sometimes more than 100feet,but a relatively long wavelength,as it's a high wave.
Waves generated in the same way can have great differences in amplitude and wavelength.For example,think back to the cruise ship.While each ship creates waves caused by the movement of the boat,the properties of each of the waves may be very different.For example,a larger cruise ship,with powerful engines,may create a wave that has high amplitude and a short wavelength.However,if the ship's engines slow down,they may then start creating less powerful waves at a slower rate.This would cause the waves'amplitude to decrease,but its wavelength to increase.

74.What does the phrase"steer clear of a cruise ship's wake"in the 1st paragraph meanC?
A.keep awake while steering a ship
B.get a clear view of what is ahead
C.keep away from the cruise ship
D.follow the cruise ship very closely
75.The author gives an example of wave people do in the stadium in order toD.
A.illustrate how excited people are in a basketball stadium
B.clear the confusion over measuring the wave's amplitude
C.demonstrate how to make waves in a basketball stadium
D.explain why the water appears to move along the waves
76.The last paragraph gives us the impression thatB.
A.the wave's amplitude may vary,but its wavelength remain the same
B.the move powerful the ships engines are,the higher the waves they generate
C.the amplitude of a wave depends on the direction the water moves forward
D.measuring the amplitude and wavelength of waves is not quite easy
77.What is this passage mainly aboutA?
A.How waves are created and measured.
B.What makes the sea water move forwards.
C.Why people create waves in the stadium.
D.How to steer a cruise ship in the rough sea.

7.Dear David,
I'm glad you would like to share your feelings with me.It's hardly surprising that your feelings of not being"grown up"have come on strongly at this point in your life,just before you're about to become a father.You are asking:will I make a good father?How will I cope?Should I have brought another little person into the world?Can I provide for it?Heeelp!I think nearly every sensitive about-to-be-parent must have these occasional feelings of self-doubt and inadequacy (不適) before the birth and it would be most unusual if you didn't share them.
It's difficult,honestly,to feel grown-up unless you have something less grown-up to relate to.A hen-pecked (懼內(nèi)的) boss may feel like a seven-year-old when he's at home.But as he walks through the office door,and knows he's going to be surrounded by staff looking to him for advice,he grows into a fully mature man.And I think it's a mistake to imagine that we all feel,as we age,a kind of progression of states,from the baby to the adult.Most people feel,on Tuesday,about three years old,and on a Wednesday,around 80.I remember feeling very grown-up at eight,a time when I was weighed down with responsibility.These days,much older,I can,in the company of people I feel at ease with,feel like a young girl.
There's a common remark that"all men are little boys",but it's not true.It's more true that men often behave like little boys.But nearly all people,at some moments in their lives,are capable of great maturity.
Once your baby arrives,you'll soon feel less childlike,or rather,less often.When your child tries to put its fingers into the electric plug,the adult in you will rise up to prevent it.You'll see you have very little in common with a needy child,particularly if it's looking to you for comfort and support.
Comfort yourself,David,with two truths.One is that your friends laugh when they talk about this subject because they,like you,feel frightened.And remember that people who haven't grown up don't go around talking about the fact that they don't feel grown-up.
Hope my advice will be helpful and good luck to you and your little one.
Sincerely Yours,
Miss Advice
43.According to the passage,Miss Advice thinks David's self-doubtB
A.valuable     B.natural          C.unusual      D.bearable
44.From Paragraph 2,we can learn that people's sense of maturityC
A.will increase with age
B.is obviously seen at home
C.changes with different situations
D.becomes stronger with familiar people
45.Miss Advice holds thatC.
A.a(chǎn)ll men behave like little boys
B.people tend to laugh at the subject
C.men with a baby feel more grown-up
D.people enjoy talking about their immaturity
46.Miss Advice wrote the letter toB.
A.teach people how to grow up
B.offer suggestions to a future father
C.encourage people to be responsible
D.solve problems of the less grown-u.

1.Having a great collection of books at home doesn't really mean that you are a person who has a passion for literature and reading. It can be a family inheritance or it can be just to impress people around you by the fact that you are a person of culture. On the other hand,there are many persons who cannot afford to buy books,because some of them are quite expensive,but who usually go to libraries and spend hours reading something that interests them a lot,or just borrow books to home.
From my point of view,literature is very important in our life. For example,reading is a means of gaining culture and enriching our knowledge in different areas. It can help us have a great imagination and it makes things easier when it comes to make compositions on different themes. It gives you the possibility to speak about science,even if you don't work in this domain,or you can express your opinion about a political aspect,just because you have read something connected to that.
Secondly,literature offers us the possibility to enter the world of imagination,and to leave the real one for a couple of hours. We come to meet kings and queens many years ago,dream of being in the world of the rich or imagine how life will be in the future. Sometimes,we identify ourselves with the characters in the stories we read and they can give us some clues to solve our problems and how to react in certain circumstances.
In conclusion,I would like to say that literature is the perfect means to enrich our culture,to express ourselves correctly,to have a rich vocabulary,to be able to interfere in conversations in different fields of interest and to really be considered an erudite person.
71. People who are fond of literature are those thatA
A. have much interest in reading          
B. keep many books
C. go to libraries every day              
D. buy expensive books in the bookstore
72. According to the author we can broaden our knowledge byD.
A. composing           B. imagining      C. communicating      D. reading
73. We can know from the third paragraph thatC
A. we can bring kings and queens back to life
B. it is very good for us to stay alone for some hours
C. what we read can be useful in our daily life
D. we can make friends with people in the stories
74. The underline word"erudite"in Paragraph 4 probably means"A".
A. learned        B. enthusiastic      C. smart         D. creative
75. What is the author's purpose by writing the passage?C
A. To share his own reading experience.      
B. To distinguish the true readers.
C. To attract people to literature.          
D. To stress the importance of imagination.

5.Dear Mom,Clear My Calendar
September is around the corner,and some of us are already complaining about summer's end.But parents have a special reason to do so.The end of summer means the start of school.And these days,planning a young child's schedule is a big challenge.The challenge is no longer finding activities to fill a child's day; it is saying no to the hundreds of options available.Our mailbox is filled with brochures urging us to sign our kids up for classes from cooking to martial arts(武術(shù)).
Educators are themselves discouraged by the number of special classes that many children attend.In the name of"enrichment,"three-year-olds not only go to preschool in the morning but study French or gymnastics after lunch.One teacher tells of a four-year-old asking for help in the toilet before hurrying off to tennis.Another teacher says that children sometimes hold on to her at pickup time.What happened to unstructured time?
A generous explanation is that we enjoy giving children opportunities we never had.The truth however is that many parents have doubts about how much time they spend away from their families.And one way to reduce this guilt is to believe that time spent in these classes is somehow more beneficial to children than the time we know we should be giving them ourselves.
David Elkind,an expert on children,suggests that the 1960s gave birth to the belief that earlier is better.Parents hope that early music lessons,for example will build a child's confidence.The truth,however,is that any time children are asked to do too much,too soon,they are at greater risk for feelings of failure.
A child's time does not have to be planned to be meaningful.Remember the lazy days of summer?Some children sleep late and play with the kids across the street until it's time to come home for dinner.However,with the majority of mothers working,fewer children enjoy that idle (空閑的) time now.
Come September,children across the country will finish a full day of kindergarten,only to attend an after-school program until 6P.M.,when a working mom or dad comes to take them home.That's too much for a five-year old.Finances,of course,do limit some parents.But let's be honest with ourselves-our own busy schedules,whatever they involve,are no excuse for burdening a young child's.

67.The author holds that it's a challenge to plan a schedule for a child mainly becauseC.
A.a(chǎn) child's schedule is too complex
B.a(chǎn)ctivities suitable for kids are limited
C.parents are stuck in numerous choices
D.children always say no to parents'advice
68.What the two teachers say in Paragraph 2implies thatC.
A.children love to stay at school
B.they are popular with children
C.children dislike after-school classes
D.a(chǎn)fter-school classes are of poor quality
69.According to the author,what is the real reason for parents to send their children to after-school classes?D
A.Parents want to make up for their own regrets.
B.After-school classes develop children's potential.
C.Parents have doubt about their own ability to guide children.
D.After-school classes give parents an excuse for being absent.
70.Which of the following will the author probably agree with?C
A.For children's benefits,the earlier the better.

6.The Nez Perce Indians are a tribe that lived in the Pacific Northwest of the United States.At the time of the Lewis and Clark expedition(遠征隊),which was one of the first journeys by Americans from the Atlantic coast to the Pacific coast and back again,the Nez Perce territory(領(lǐng)土) covered about 17million acres,covering parts of Washington,Oregon,and Idaho.But that was a brief sweet history.
In September 1805,when Lewis and Clark came off the Rockies on their westward journey,the entire exploring party was hungry and ill-too weak to defend themselves.Had the Nez Perce chosen to attack them,they could have put an end to the Lewis and Clark expedition there on the banks of Clearwater River.Instead the Nez Perce welcomed the white Americans and looked after them until they made a full recovery.
Thus began a long friendship between the Nez Perce and white Americans.But white men's greed for land and gold finally broke the friendship.
In 1855Governor Isaac Stevens of Washington Territory invited the Nez Perce to a peace conference.He said there were a great many white people in the country,and many more would come.But the chief of the tribe at that time,Old Joseph,replied,"Take away your paper.I will not touch it with my hand."
Things were quiet for a while after that,but not for long.When Old Joseph died,the chiefship was passed onto Young Joseph.In the late 1870s,government officials came to order the Nez Perce to leave the Wallowa Valley and then began hard battles between the Nez Perce and the white soldiers.After the tribe had fought thirteen battles and moved 1,600miles towards Canada in an attempt to retreat (撤退) north,Young Joseph,gave in to the United States Army.Here was his famous statement,"Hear me my chiefs.I am tired; my heart is sick and sad.From where the sun now stands I will fight no more forever."
In 1885,Chief Joseph was sent along with many of his band to the Colville Reservation in Washington where Joseph continued to lead his band for another 25years,at times coming into conflict with the leaders of 11other tribes living on the reservation.
