Machines in the home have a short history. Sewing machines, washing machines and tumble dries are common enough today, but a hundred years ago few people could even imagine such things. However, inventors have designed and built a wide range of household machines since then. In most cases the inventor tried to patent（申请专利）his machine, to stop anyone copying it. Then he tried to produce a lot of them. If the machine became popular, the inventor could make a lot of money.
In 1790 the first sewing machine was patented. The inventor was an Englishman called Thomas Saint. There was nothing to match his machine for forty years, and then someone built a similar device. He was a Frenchman, Bartelemy Thimonier. However, neither of these early machines worked very well. It wasn’t until 1846 that an inventor came up with a really efficient sewing machine. He was an American, Elias Howe and his machine was good enough to beat five skilled sewing women. He didn’t make much money from it, however. The first commercially successful sewing machine was patented by Isaac Singer five years later.
Today, we take washing machines for granted, but there was none before 1869. The revolving drum（旋转桶）of that first machine set a pattern for the future, but it was crude by today’s standards. The drum was turned by hand, and needed a lot of effort. Eight years passed before someone produced an electric washing machine. The world had to wait even longer for a machine to dry clothes. The first spin-drier was another American invention, patented in 1924; but it was 20 years before such machines were widely used.
It was yet another American, called Bissell, who introduced the carpet sweeper. He patented the original machine back in 1876. It didn’t pick up dirt very well, but it was quicker than a dustpan and brush. Thirty-six years later, even the carpet sweeper was old-fashioned: modern homes now have a vacuum cleaner（吸尘器）with an electric motor to suck the dust.
72. Whose sewing machine could do as much as,or even more than the work of five skilled sewing women?
A. Thomas Saint’s. B. Bartelemy Thimonier’s.
C. Elias Howe’s. D. Isaac Singer’s.
73. According to the article, modern inventors __________ .
A. follow the pattern of the first revolving drum but improve it much
B. only imitate (模仿)the first washing machine
C. power the first ever-made washing machine by electricity
D. have to wait for the first spin-drier for a long time
74. The underlined word “crude” in the sentence “but it was crude by today’s standards” probably means __________ .
A. useless B. ugly-looking C. rough D. not skillfully made
75. The article mainly tells us about __________ .
A. the great inventors in the world
B. the important inventions in the world
C. the short history of household machines
D. the importance of the machines used in the home

Advice to “sleep on it” could be well founded, scientists say. After a good night’s sleep a problem that seemed impossible to solve the night before can often appear more manageable, although no evidence has proved this by now. But researchers at the University of Luebek in Germany have designed an experiment that shows a good night’s sleep can improve insight (洞察力) and problem-solving.
“If you have some newly acquired memories in your brain, sleep acts on these memories and restructures (重构) them, so that after sleep the insight into a problem which you could not solve before increases,” said Dr. Jan Born, a neuroscientist (神经科学家), at the university. To test the theory, they taught volunteers two simple rules to help them put a string of numbers into a new order. There was also a third, hidden rule, which could help them increase their speed in solving the problem. The researchers divided the volunteers into two groups: half were allowed to sleep after the training while the rest were forced to stay awake. Born and his team noticed that the group that had slept after the training were twice as likely to figure out the third rule as the other group. “Sleep helped.” Born said in a telephone interview. “The important thing is that you have to have a memory representation in your brain of the problem you want to solve and then you sleep, so it can act on the problem.” But Born admitted that he and his team don’t know how restructuring of memories occurs or what governs it. Pierre Marquette and Pierre Ruby of the University of Liege in Belgium said the experimental evidence supports the suggestion that sleep can help develop creative thinking. Although the role of sleep in human creativity will still be a mystery, the research gives people good reason to fully respect their periods of sleep, they added.
68. The underlined phrase “sleep on it” in Paragraph 1 probably means _____.
A. to put something to be solved aside until the next day
B. to get as much sleep as possible
C. to go on sleeping without being disturbed
D. to sleep till you usually get up the next morning
69. Jan Born and his team carried out the experiment through _____.
A. interview B. comparison C. surveyD. imagination
70. It can be inferred from the passage that _____.
A. sleep is the only way to solve hard problems
B. people should sleep so long as they have time
C. people know how sleep reconstructs memories
D. people have various periods of sleep
71. What would be the best title for the passage?
A. How Sleep Works B. No Evidence, but Well Founded
C. Sleep Helps Solve Problems D. Born’s Discovery On Sleep

Every family with kids has seen its share of arguments, shouting and complaining. It turns out that all those conflicts serve an important purpose in the development of children . Saying “no” followed by a bad temper, just may be an unavoidable part of growing up. And that’s a good thing. These are the first steps toward independence. Even young children have to challenge their parents sometimes. Studies have shown the following:
·Although stressful, conflicts are beneficial for children.
·Learning to manage conflicts is necessary for a child’s development.
·Conflicts during the preschool years occur because children desire even more attention than parents can or should give.
If you understand why conflicts occur, it can minimize the conflicts between you and your children. Conflict is a child’s attempt to develop a sense of self and how he or she learns to express his or her needs and ideas. Parents develop and drive this independence by putting children to the outside world both formally and informally.
Conflicts can grow out of a difference of opinion or might just be a way to blow off steam(发脾气) . In rare situations, constant conflicts between parents and children can indicate a deeper emotional problem. Consult your doctor if this seems to be your situation.
It’s important to offer your child choices, which should be determined by age and developmental level. The more responsible a child is, the more choices he or she gets in reward. You can threaten your child with punishment, but often offering a choice will better improve angry situations. Consequences and rewards should have some meaning to your child.
Often a child’s adverse(敌对的)reaction when he or she hears the word “no” can be avoided by giving the child an explanation as to why you have refused his or her request.
60. Why does the author think conflicts are good?
A. It’s a sign that children are trying to be independent.
B. Children can learn to control the bad temper.
C. This can develop a better way of communication.
D. It can improve the relationship between parents and children.
61. A 3-year-old boy challenges his parents angrily, according to studies, because he may,
A. feel being ignored by his parents.
B. get tired of being looked after by his parents.
C. want to stay with his parents at any time.
D. be blamed by his parents for his faults.
62. In most cases , the conflicts between parents and their children.
A. lead to more misunderstandingsB. don’t hurt feelings
C. are highly valued by parents D. involve visiting doctors
63. What can be concluded from the passage?
A. Children understand what their parents think of clearly.
B. Children enjoy giving their opinions by conflicting with their parents.
C. Most parents would rather punish their children than reward them.
D. Communication can reduce conflicts between parents and children.

Watson entered Mr Smith’s office. The Boss was a hard man. He fired people who didn’t do well without giving them a second chance.
“Watson,” said Mr Smith, “this past year your department hasn’t earned money. We’re going to drop that department. It’s finished. I’ m sorry, —but you’ll have to go.” “But, sir—if I just had a little more time. For the moment I need the job to keep my son at Riverside School.”
“What’s that!” said the Boss. “Riverside! I didn’t know you had a boy there. That’s an expensive school for a man with your salary.”
“1 know, sir. But he likes it there so much! He’s a star trackman（田径运动员） and the best boxer in the school. The boys call him Champ（冠军） there.”
The Boss sat perfectly still for a long time—a faraway （恍惚的） look in his eyes. Then, suddenly, he said, “We’ve got to close your department, Watson. But you’ll take over a new job in another department. It means longer hours—maybe more pay. Now get out. You’re here for life.”
Watson got out, with surprise in his face. Then the Boss took a letter from the top drawer of his desk. It was Herbie’s last letter from Riverside School —written a few days before he died. He had read it over and over again with sick pain. The letter read:
I can’t say the boys here are any nicer to me than the others were. I guess it’s the same everywhere when you’re a cripple (跛脚的人). But don’t worry about me, Dad. They’ve got a good chemistry department here. And there’s one boy here who is really great. He’s a track star and boxing champ and just tops in chemistry. The boys call him Champ. He made them stop throwing my books around. And he knocked a boy down who hit me. He is the best friend I ever had. Dad, when I grow up, I want to do something for Champ. Something big—that he won’t even know about.
Your son,
Herbie
