If Mickey Mouse slips (滑倒)on a banana skin on TV, viewers laugh. But for ordinary people, falling is not 36 . For example, if you 37 off your bike, you have to take days to get well. For 38 people, the result of a fall could be worse.
Scientists at the University of Pittsburgh, USA, wanted to know why some people are 39 likely to fall than others.
The researchers found that 40 means more than putting your feet on the ground and standing tall. Your brain 41 your sense of balance with information from your eyes and inner ears and the 42 from your feet and legs. If something goes wrong with any of these, you’re 43 to fall. People 44 to fall more often as they grow older because their senses are slower.
State of mind is important too. The research shows that when people know they’re walking on a slippery surface, they 45 their pace and walk with flatter feet. As a result, they fall less often.
“We actually 46 people slip and fall,” researcher Mark Redfern said. People of different ages fall on 47 in his lab. Cameras 48 their falls and a computer analyzes the information. Scientists then can 49 people who fall often how to be more watchful.
“If they get 50 to a lifelike but controlled environment, people can 51 learn to handle the 52 thing,” Redfern said.
Falls happen to everyone sometimes. 53 you see someone fall, think about why and offer a helping 54 . This person’s painful experience may 55 you from falling at the same place.

The legal limit for driving after drinking alcohol is 80 milligrams(毫克) of alcohol in 100 milliliters of blood, when tested. But there is no sure way of telling how much you can drink before you reach this limit. It varies with each person depending on your weight, your sex, and
what sort of drinks you’ve had. Some people might reach their limit after only about three standard drinks.
In fact, you r drinking ability can be affected by just one or two drinks. Even if you’re below the legal limit, you could still be taken to court if a police officer thinks your driving had been affected by alcohol.
It takes about an hour for the body to get rid of the alcohol in one standard drink. So, if you have a heavy drinking in the evening, you might find that your driving ability is still affected the next morning, or you could even find that you’re still over the legal limit. In addition, if you’ve had a few drinks at lunchtime, another one or two drinks in the early evening may well put you over the legal limit.
In a test with professional drivers, the more alcoholic drinks they had had, the less able they were to do it!
So the only way to be sure you’re safe is not to drink at all.
Alcohol is a major cause of road accidents. One in three of the drivers killed in road accidents have levels of alcohol which are over the legal limit, and road accidents after drinking are the biggest cause of death among young men. More than half of people stopped by the police to take a breath analyzer test have a blood alcohol concentration (浓度) of more than twice the legal limit.
It is important to remember that driving after you’ve been drinking doesn’t just affect you. If you’re involved in an accident, it affects a lot of other people as well, not least the person you might kill or injure.
59. Which of the following statements is NOT true ?
A. Three standard drinks may cause some people to reach the legal limit .
B. There is no sure way of telling how much you can drink before you reach the legal limit .
C. The legal limit for driving after drinking is 0.08g of alcohol in 100 milliliters of blood.
D. The amount of alcohol a person can drink before reaching legal limit is the same for
different people.
60. We may infer that even a professional driver will find hard to pass through a driving test if he
drinks_______.
A．heavily B．a little C．every day D．occasionally
61. This passage indicates that ________.
A．a driver who does not take any alcohol will not die in road accidents.
B．those who drink must be killed.
C．more young men die in drink-related accidents than in any other way.
D．one in three of the drivers often drinks a lot.
62. One of the writer’s purposes in writing the passage is to tell you that_________.
A．young men should never drive quickly.
B．driving after drinking may put many lives at risk.
C．safe drinking is impossible.
D．the manner of drinking is meaningless.
C
Be careful of those who use the truth to deceive〔欺骗〕. When someone tells you something that is true，but leaves out important information that should be included，he can create a false impression.
For example，a man once told me, “I just won a hundred dollars on the lottery(彩票). It
was great. I took that dollar ticket back to the store and turned it in for one hundred dollars！”
This guy’s a winner，right？Maybe, maybe not. Then later I discovered that he bought two hundred tickets，and only one was a winner. He was really a big loser！
He didn’t say any thing that was false, but he omitted important information on purpose. That’s called a half-truth. Half-truths are not technically lies, but they are just as dishonest.
Untrustworthy candidates（候选人）in political campaigns often use this trick. Let’s say that during Governor Smith’s last term, her state lost one million jobs and gained three million jobs. Then she seeks another term. One of her opponents（对手）runs an ad saying, “During Governor Smith’s term, the state lost one million jobs！”That’s true. However，an honest statement would have been quite different.
Advertisers will sometimes use half-truths. It’s against the law to make false claims, so they try to mislead you with the truth．An ad might blow its own horn, “Nine out of ten doctors use Yucky Pills to cure nose diseases.”It fails to mention that they only asked ten doctors; and nine of them work for the Yucky Corporation.
This kind of deception(欺骗) happens too often. It’s a sad fact of life: Lies are lies, and sometimes the truth can lie as well.
63. According to the passage, which of the following is true?
A. Governor Smith often tells half truths.
B. Important information can create a false impression.
C. Whenever people tell the truth, they are really lying.
D. Sometimes the truth can be used in dishonest ways.
64. The underlined word “omitted” ( paragraph 4 ) means________.
A. gave up
B. left out
C. told about
D. found out
65. From the passage, we can learn that________.
A. during Governor Smith’s last term, her state got a net gain(净增) of three million jobs
B. the man who says he won l00 dollars on the lottery actually lost 100 dollars
C. advertisers and politicians often break the law by making false claims
D. 90 percent of the doctors believe Yucky Pills can cure nose diseases
66. What is the writer’s purpose in writing this passage?
A. To explain the relationship between truths and lies.
B. To tell people what half-truths really mean.
C. To advise people to be honest in giving information.
D. To warn people to be careful of what they read and hear.
D
A proud father has named his son after a computer software term.
Jon Blake Cusack, from Mocjogam, told local newspapers: the US traditional way of adding “Junior” or “II” after a boy’s name was too common. So, when his son was born last week, he chose the name Jon Blake Cusack2.0, as if he were a software upgrade.
Mr. Cusack admitted that it took months to persuade his wife, Jamie, to accept the idea .Mrs. Cusack said she asked several friends whether they could accept this name or not.
All the men, she said, felt the name was “cool”. However, her women friends did not thin k so. “I think the women end up like it,” she said.
Mr. Cusack told the local newspaper he got the idea from a film called The Legend of 1900, in which an abandoned baby is given the name 1900 to remember the year of its birth.
“I thought that if they can do it, why can’t we?” he said.
After little Jon version 2.0 was born, Mr. Cusack even sent a celebratory e-mail to the family and friends designed to look as though he and his wife had created a new software.
“I wrote things like there are a lot of new features from Version 1.0 with additional features from Jamie”, he said. And he is already planning for his son’s future. “If he has a child, he could name it 3.0”, he said.
67．From the passage we know that “Jon Blake Cusack 2.0”.
A．shows the traditional way of America baby naming
B．is also the name of a computer
C．has the same meaning as “Jon Blake Cusack Junior”
D．tells something about the hope the father places on his baby
68．What do the name of “1900”and “Jon Version 2.0”have in common?
A．They are both connected with computer. B．They are both untraditional.
C．They both tell about the births. D．They are to be equally popular. 69．Which of the following is true according to the passage?
A．Mrs. Cusack didn’t agree to name her son after a computer software term at the very beginning.
B．All Mrs. Cusack’s friends support their idea.
C．When Mr. Cusack had a second child, he would name it “Jon Version 3.0”.
D．The name “1900”is also a computer software term.
70．What does Mr. Cusack’s “Version 1.0”refer to in the last paragraph?
A．A computer software. B．Mr. Cusack.
C．Mr. Cusack and his wife. D．Mr. Cusack’s grandson.
71.Why did the man name his son after a computer software?

B. He is a computer producer
C. He wanted to do something untraditionally
D. He did it as usual

I’m walking on a path in the forest in the Central African Republic. Unexpectedly, I’m face-to-face with the gorilla, who begins screaming at 2 top of her lungs. That makes her baby scream, and then a 400-pound male appears. He screams the 3 (loud) of all. The noise shakes the trees as the male beats his chest and charges toward me. I quickly lower myself, ducking my head to avoid 4 (look) directly into his eyes so he doesn’t feel 5 (challenge). My name is Mireya Mayor. I’m a 6 (science) who studies animals such as apes and monkeys. I was searching 7 these three western lowland gorillas I’d been observing.

True to a gorilla’s unaggressive nature, the huge animal 9 (mean) me no real harm.

华美实验学校 高三英语限时训练（六） 第一部分阅读理解（共9小题；每小题2分，满分18分） 第一节: 阅读下列短文，从每题所给的四个选项中选出最佳选项。 Planning a visit to the UK? Here we help with ways to cut your costs. AVOID BIG EVENTS Big sporting events, concerts and exhibitions can increase the cost of accommodation and make it harder to find a room. A standard double room at the Thistle Brighton on the final Friday of the Brighton Comedy Festival (19 Oct.) cost ￡169.15 at https://www.doczj.com/doc/c416793343.html,. A week later, the same room cost ￡118.15. If you can be flexible and want to know dates to avoid—or you?re looking for a big event to pass your time—check out sites such as https://www.doczj.com/doc/c416793343.html,, which allow you to search for events in the UK by city, date and category. STAYAWAY FROM THE STATION If traveling to your destination by train, you may want to find a good base close to the station, but you could end up paying more for the sake of convenience at the start of your holiday. Don?t be too choosy about the part of town you stay in. Booking two months in advance, the cheapest room at Travelodge?s Central Euston hotel in London for Saturday 22 September was ￡95.95. A room just a tube journey away at its Covent Garden hotel was ￡75.75. And at Farringdon, a double room cost just ￡62.95. LOOK AFTER YOURSELF Really central hotels in cities such as London, Edinburgh and Cardiff can cost a fortune, especially at weekends and during big events. As an alternative consider checking into a self-catering flat with its own kitchen. Often these flats are hidden away on the top floors of city center buildings. A great example is the historic O?Neill Flat on Edinburgh?s Royal Mile, available for ￡420 for five days in late September, with rooms for four adults. GET ON A BIKE London?s …Boris bikes? have attracted the most attention, but other cities also have similar programmers that let you rent a bicycle and explore at your own pace, saving you on public transport or car parking costs. Among the smaller cities with their own programmers are Newcastle (casual members pay around ￡1.50 for two hours) and Cardiff (free for up to 30 minutes, or ￡5 per day). 1. The Brighton Comedy Festival is mentioned mainly to show big events may ________. A. help travelers pass time B. attract lots of travelers to the UK C. allow travelers to make flexible plans D. cause travelers to pay more for accommodation 2. The passage shows that the O?Neill Flat ________. A. lies on the ground floor B. is located in central London

His mother had kept on hinting that there would be a big surprise for him during the vacation. Kevin took out his scrapbook (剪贴簿). The exams had just finished, and summer vacation had just started. Now he was free as a bird — free to draw, paint, play basketball, and watch television…anything he wanted to do. Suddenly, the doorbell rang, startling (使惊吓) him. It was his pain of a cousin, Max. “Hi!” screamed Max as he jumped on Kevin’s bed. “I have come to stay here for the holidays.” Kevin had never expected his mother’s surprise to be this bad. If this was the start of his vacation, then the next few weeks were going to be the worst experience of his life. The next few days were horrible for Kevin. After breakfast, Kevin decided to make a painting. Luckily, Max was not around. Kevin spread out all his art supplies and started painting some beautiful scenery. When he was doing the finishing touches, Max entered the room with a Pepsi bottle. He slipped on some water, spilling Pepsi all over the painting and totally ruining it. The next day was even worse. Everything was peaceful until the evening. It all started when Max put the dirty clothes in the washing machine. After some time, Kevin heard some strange sounds from the washing machine. He went to check and found that Max had put his best pair of shoes into the machine, along with the clothes. One day, Kevin was looking through the newspaper when some interesting news caught his attention. He read it aloud: “The world famous philatelist (集邮家) Dick Brown’s stamps were stolen last week from his house. Several other stamp robberies also have taken place, and police suspect that all the robberies are linked.” This piece of news concluded by warning all stamp collectors to keep their stamps safe.

One summer day 36 I was headed over to the administration building, I heard someone call my name. I 37 around and saw Philip, one of my colleagues standing with another young man. As Philip introduced me to the young man, named Stephen, he reminded him that he would be taking one of my 38 , Introduction to Literature. With a somewhat 39 expression, Stephen asked if my class was going to be “hard”. Would he be able to pass? I 40 he was concerned about failing before the 41 day of classes. We talked about what the class would 42 and I saw Stephen’s eyes getting b ig with 43 .

Still, he managed to 50 most of his courses by being in class every day, turning in all of his assignment on time and breaking down his studying into 51 digestible parts. By passing course after course he began to gain a measure of self-respect. He was a great singer and he was 52 the school’s cross-country team. Every time I saw him on campus, he would brighten up and say, “O ne bite at a time.”Whenever he introduced me to his friends, he would tell them that he was 53 when he was supposed to be failing.

A Famous centenarians (百岁老人) still active in arts, science are in no mood to retire. "Those who stand still, die," is one of Oliveira's favorite phrases. He knows from experience what it means, as the Portuguese film director has reached the age of 102 and is still active in his profession. Every year, Oliveira shoots a film and is currently working on his next project. "You have to work, work, work in order to forget that death is not far away," he said. When asked about his age, Oliveira said with some humility: "It's down to mother nature. It gave to me what it took from others." Being both mentally and physically fit in old age is partly a matter of luck, but it also has something to do with character. Not every white-haired person is wise and social skills, openness and the ability to train the brain are essential for senior citizens. Along with the architect Oscar Niemeyer (103), Nobel laureate Montalcini (101) and director Kurt Maetzig (100), Oliveira is one of those people of whom it would be very wrong to think as members of a listless elderly generation. Another master in his profession is the architect Oscar Niemeyer. The 103-year-old Brazilian is best known for his futuristic-looking（未来派的）buildings in Brasilia, but he also speaks out on behalf of the poor. "The role of the architect is to struggle for a better world where we can develop a form of architecture that serves everyone and not just a privileged few," said Niemeyer recently. He spends almost every day working in his office in Copacabana, and even when he falls ill he keeps working on ideas: After a gallbladder (胆囊) operation he composed a samba tune (桑巴舞曲) in the clinic. Another man who could sing a song about age is 107-year-old Heesters. The Dutch-born opera singer spent most of his life performing in Germany, where he still works. Recently Heesters said: "I want to be at least 108-years-old." He also plans to keep performing. "Should I just sit at home and wait until they come and pick me up?" Heesters has not given up trying to add to his tally of awards and is looking for a "good stage role". Italian scientist Rita Levi-Montalcini, who is 101-year-old and is still active in medical science, has described the force that keeps driving her on: "Progress is created through imperfection." In 1986 she and her lab colleague were awarded the Nobel Prize for Medicine for their work on nerve growth factor. She's convinced that humans grow on challenges.
限时规范练35(选修6Module5) 核心素养关键词:培养学生人与社会、克隆科技的素养能力意识 一、阅读理解 A The news that researchers have used cloning to make human embryos for the purpose of producing stem cells may have some people wondering if it would ever be possible to clone a person.Although it would be immoral,experts say it is likely biologically possible to clone a human being.Since the 1950s when researchers cloned a frog,scientists have cloned dozens of animal species,including mice,cats,sheep,pigs and cows. With mice,researchers are able to use thousands of eggs,and conduct many experiments,to work out these problems.“It’s a numbers game,” said Dr.Robert Lanza,the chief scientific officer at a biotech company.“But with primates (灵长类动物),eggs are very precious,and it is not easy to get them to conduct experiments.” In addition,researchers can’t simply apply what they’ve learned from cloning mice or cows to cloning people.Cloning an animal requires that researchers remove proteins that are necessary to help cells divide.In mice,this isn’t a problem,because the embryo that is created is able to make these proteins again.But primates aren’t able to do this,and researchers think it may be one reason that attempts to clone monkeys have failed. What’s more,cloned animals often have different kinds of abnormalities.These abnormalities are common because cloned embryos have just one parent rather than two,which means that a process known as “imprinting (印记)” does not occur properly in cloned embryos. “Problems with imprinting can result in extremely large embryos,which leads to problems with blood flow for the baby,” Lanza said.“The extremely high rate of death and the developmental abnormalities from cloning make cloning people immoral.It’s like sending your baby up in a rocket knowing there’s a 50-50 chance that it’s going to explode.” 1.What can we learn from Paragraph 1?
