You want to know where the safest place for young children is in the car? For a child of any age, the back seat is the safest place and the safest part of the back seat is the middle.In the back seat, the child is farthest away from the force or effect of head-on collision(撞擊), which can cause the most injuries.
All fifty states of the USA have laws requiring the use of safety seats for young children.If you have children under 8 years of age weighing no more than 80 pounds, it is necessary to fit your car with a special child safety seat.
The child safety seat comes in three types or sizes: the first type is designed for babies from birth to one year of age, until the baby weighs about 20 pounds; the second size is for children between one and four years of age, who weigh between 20 and 40 pounds; the third kind is used by older children big enough to use the car's belt system.Moreover, all these safety seats must be fitted and held in place on the car's back seat.If your child does need your attention while you are driving, don't look back.Just pull over (?柯愤叄.
In addition, always be sure your child is properly fastened throughout the entire trip.Children who can unfasten their own car seats are subject to fatal injuries in an accident.Start early in your child's life teaching them that car safety is serious business and make sure you give a good example and always wear your own seat belt.
56.This passage mainly discusses _____.
A.how a child can be kept safe while riding in a car
B.why the back seat is the safest place in a car
C.how a child safety seat can protect a child
D.what causes young passengers the most injuries

A.a(chǎn)bove eight years of age
B.between four and eight
C.weighing between 20 and 40 pounds
D.weighing more than 80 pounds
59.What safety tip is given in this passage?
A.Always keep your children beside you.
B.Fasten your own safety belt to set an example.
C.Make your child remain seated during the trip.
D.Study laws requiring the use of safety seats.
I hate Father's Day.The reason is that I have two dads, and come the third Sunday of every June, I feel like I'm letting them both down.
I didn't always feel this way.Father's Day and I actually got off to a good start.Even though my parents divorced when I was four, I could spend Father's Day with my dad.I'd make my dad a card and then go to the mall to buy him a book or a CD.
The first change started when I got a new father, Jim.He was a short guy with a big belly.Something about him suggested ease (自在) a marked contrast to my dad, who'd go crazy at the drop of a Coke.I began to look forward to Jim's visits.When my mom said they were getting married, I didn't care.
Some men are meant to be fathers, but not necessarily fathers to children of any age.When I was still young enough to be bribed (收買) with a gift, Dad was great.My dad was the kind of guy who is easily annoyed and prefers volume (音量) to reason.Gradually, I found Jim was more comfortable to be around.He soon became the dad I would go to for help with homework, to fix toys and to talk to teachers.He offered great comfort.
It took a few years for me to call Jim "Dad".I'd never used the cold word "stepfather" with Jim.I just called him Jim.I guess I believe a father is a man who performs the duties a father should.Jim has done everything I imagine a "real" dad is supposed to do.So come next Father's Day, he'll also be the one I'll hug, and say "I love you" to.
60.What kind of person was the author's birth father?
A.He was hot-tempered. B.He was generous.
C.He was easy-going. D.He was reasonable.
61.What can be said about the author when he was still young?
A.He was very close to his father. B.He thought his father was great.
C.He couldn't tolerate his father. D.He didn't like his father.
62.The author liked Jim because ______.
A.Jim married his mother B.Jim was helpful and responsible
C.Jim lived with his family D.Jim often bought him gifts
63.It can be inferred from the last paragraph that ______.
A.the author never called Jim Dad
B.the author doesn't respect his father
C.the author regards Jim as his father as well
D.the author will ignore next Father's Day

Many visitors find the fast pace at which American people move very troubling.One's first impression is likely to be that everyone is in a rush.City people always appear to be hurrying to get where they are going and are very impatient if they are delayed even for a brief moment.
At first, this may seem unfriendly to you.But drivers will rush you; storekeepers will be in a hurry as they serve you; people will push past you as they walk along the street.You will miss smiles and conversations with people as you shop or dine away from home.Do not think that because Americans are in such a hurry they are unfriendly.Often, life is much slower outside the big cities, as is true in other countries as well.
Americans who live in cities such as New York, Chicago, or Los Angeles, often think that everyone is equally in a hurry to get things done; they expect others to "push back", just as city people do in Tokyo, Singapore or Paris, for example.But when they discover that you are a stranger, most Americans become quite kindly and will take great care to help you.Many of them once came to the city as strangers and they remember how frightening a new city can be.If you need help or want to ask a question, choose a friendly-looking person and say, "I am a stranger here.Can you help me?"
Most Americans enjoy helping a stranger.Most people will stop, smile at you, and help you find your way or answer your questions.But you must let them know that you need help.Otherwise they are likely to pass you by, not noticing that you are new to the city and in need of help.

Science journalists spend a great deal of time educating their editors about their fields, and by and large those efforts lead to better stories.But there's one place we hit a wall.No, it's not that the editors aren't smart enough to understand science.Actually, it's the opposite: they are too accustomed to being smart, and thus can't deal with the fact that they don't understand it.
I was discussing this problem recently with a colleague who had been beating his head against the wall for months trying to get a story about a mysterious "dark force" in cosmology (宇宙學) past editors at The New Yorker."They kept saying they didn't understand it!" he complained.Well, of course they didn't understand it.Nobody understands it.That's what makes it so interesting.
In science, feeling confused is essential to progress.An unwillingness to feel lost, in fact, can stop creativity dead in its tracks.However, editors seem to absorb difficulty differently.If they don't understand something, they often think it can't be right ― or that it's not worth writing about.They are used to being the smartest guys in the room.They forget the fact that relativity (相對論) and quantum mechanics (量子力學) have been around for nearly a century, yet they remain confusing in some sense.They just don't make sense.On the other hand, why should they? The universe doesn't care what we can or cannot believe.It doesn't speak our language, so there's no reason it should "make sense".
So it's necessary to know not only what scientists know, but also what they know they don't know.This is an unfamiliar concept to editors who are used to dealing with politics or sports.For all these reasons and more, the best editors should understand all this.Sometimes you just need to dare to be stupid.
72.What idea does the author convey in this passage?
A.Editors need to have more knowledge of science.
B.Only scientists understand what science is all about.
C.Editors should admit that they don't understand science.
D.Science has been developing very rapidly.
73.What did the author's colleague complain about?
A.The readers didn't understand his theory.
B.The editors wouldn't publish his article.
C.Nobody is able to understand "dark force".
D.Cosmology is too mysterious a branch of science.
74.What does the author think of the theories of quantum mechanics?
A.It doesn't have to make sense.
B.It can't be right.
C.It's only understood by the smartest.
D.It's not worth writing about.
75.Which of the following is the best title for this passage?
A.Editors Must Dare to Be Stupid
B.Science Is Just Beyond Us
C.The Smartest Guys Are Among Us
D.Science Is Different from Politics
