We know that cigarette smoking kills. So, producers made electronic cigarettes as a safer smoking choice - safer than tobacco. Although e-cigarettes contain the drug nicotine like cigarettes, they do not use tobacco and you do not light them. They are powered by battery (电池).
However, if e-cigarettes are so safe, why has the United States Center for Disease Control(CDC) seen an increase in telephone calls about e-cigarette poisonings?
The answer is children. Most of the calls are from people worried about children who have played with the devices, In the period of one month this year, the Center said 215 people called the Center with e-cigarette concerns. More than half of these calls were for children aged five and younger. The devices had made them sick.
Tim McAfee is director of the Center's Office on Smoking and Health, He says the problem is regulation. Meaning, the U.S. federal government does not control e-cigarettes even though they contain liquid nicotine. Mr.McAfee adds that liquid nicotine is a well-known danger. Mr.McAfee explains that nicotine poisoning happens when it gets into the skin, gets into the eyes or is swallowed. It can cause stomach pain or a sense of unbalance. And too much nicotine can kill,
Tim McAfee says e-cigarettes do not create the level of risk to people that tobacco products do.He notes that almost 500,000 Americans die each year from cigarettes. "So, cigarettes are the winner in that contest." E-cigarettes do not contain hundreds of harmful chemicals that are found in real cigarettes. So, the U.S.Surgeon General Boris D. Lushniak has suggested that e-cigarettes may be a useful tool for adults trying to end their tobacco use.
But McAfee worries that teenagers may think electronic cigarettes are harmless. They could become addicted to the nicotine and then start smoking real cigarettes. In other words, he fears that for young people fake e-cigarettes could be a "gateway" to the real thing.It can be inferred from the passage that______.
A. the CDC wants to develop a better type of e-cigarettes
B. the government is in favor of the use of e-cigarettes
C. Surgeon General Boris D. Lushniak is a heavy smoker
D. smokers most probably can't quit smoking using e-cigarettesWhat is Tim McAfee's opinion about smoking?
A.Adults should use harmless e-cigarettes. |
B.Smoking e-cigarettes can make a person sick. |
C.He claims that regulations should be made to ban smoking. |
D.He is concerned about the teens using e-cigarettes. |
The new studies show that fewer than half of the 9th graders in many of the nation’s largest cities, can ever graduate. The studies clearly show that the dropout rate isn’t dropping. And, in particular, the dropout rate isn’t dropping for poor and minority students.
Amazingly, though so many regret the rising dropout rate, our schools continue to lack formal plans--or any plans--to teach students motivation(动机). Most schools have no game plan to ensure that students understand that schooling will be completely necessary. Schools expect youth and children to act as though schooling is important, but they never teach them to believe that.
Years ago, families ensured that thechildrenrecognized the value of schooling. But in many modern families, the children may fail to recognize the importance of school life just because these families may actually tell their children that school is not important. Since many families are not motivating their children to be interested students, youth professionals, like teachers may need to provide this training. Otherwise, it is likely the dropout rate will continue not to drop, but only worsen.
Here are some strategies to convince even the most apathetic (无动于衷的) students that they must stay in school.
Ask students if they will ever need to work: The world has changed. 100 years ago, factory work was the booming job, and it required no education. Today, factories are increasingly automated. Most computer-related jobs require education and at least a high school diploma.
Ask students which century they will be prepared for: In 1900, the most common jobs were farm laborer and domestic servant—education not needed. Now, the most common jobs are office and sales staff—education and diploma usually needed. An amazing 6 out of 10 people today work in a store or office.
Ask students to devise a way that the employee could be replaced. For example, the coming trend in fast food is to use computers rather than people to run the restaurant. A prototype is apparently already being tested. The students should discover that most jobs that lack education and diploma requirements may be ripe for automation. What does the underlined part mean in Paragraph1?
A.Few students can afford to go to school in large cities. |
B.A large number of the 9th graders can graduate now. |
C.There are still quite a few 9th graders leaving school early. |
D.Most schools in large cities have fewer and fewer students. |
Without the help of youth professionals,_____.
A.more and more families will gradually recognize the value of school. |
B.it is likely that the dropout rate in schools won’t continue to drop. |
C.some parents will be more convinced of their children’s future. |
D.the schools will make proper plans to solve the problems with dropout. |
The author takes factory work for example mainly to ______.
A.tell us that many jobs requires certain education in the past |
B.show that there are more factory work and employment in modern society |
C.show that employment in the computer field grows at a high rate |
D.emphasize that modern jobs require education and schools ar![]() |
It can be inferred that______.
A.both schools and families should answer for the high dropout rate |
B.many new jobs don’t need children’s high school diploma |
C.working in a store doesn’t require a high school diploma |
D.most schools are ready to help students recognize the importance of study |
If students play the “Replace Me” game, the result would be “______”.
A.They will know that they can ‘always’ do without a diploma |
B.More of them will drop out early to go to work |
C.They will discover that lack of education is a disadvantage in choosing jobs |
D.They will become better at using computers to hunt for a job |
Today, there’s hardly an aspect of our life that isn’t being upended by the tons of information available on the hundreds of millions of sites crowding the Internet, not to mention its ability to keep us in constant touch with each other via electronic mail. “If the automobile and aerospace technology had exploded at the same pace as computer and information technology,” says Microsoft, “a new car would cost about $ 2 and go 600 miles on a small quantity of gas. And you could buy a Boeing 747 for the cost of a pizza.”
Probably the biggest payoff, however, is the billions of dollars the Internet is saving companies in producing goods and serving for the needs of their customers. Nothing like it has been seen since the beginning of the Industrial Revolution, when power-driven machines began producing more in a day than men could turn out in nearly a year. “We view the growth of the Internet and e-commerce as a global trend,” says Merrill Lynch, “along the lines of printing press, the telephone, the computer, and electricity.”
You would be hard pressed to name something that isn’t available on the Internet. Consider: books, health care, movie tickets, construction materials, baby clothes, stocks, cattle feed, music, electronics, antiques, tools, real estate, toys, autographs of famous people, wine and airline tickets. And even after you’ve moved on to your final resting place, there’s no reason those you love can’t keep in touch. A company called FinalThoughts.com offers a place for you to store “afterlife e-mails” you can send to Heaven with the help of a “guardian angel”.
Kids today are so computer literate that it in fact ensures the United States will remain the unchallenged leader in cyberspace for the foreseeable future. Nearly all children in families with incomes of more than $75,000 a year have home computers, according to a study by the David and Lucile Packard Foundation. Youngsters from ages 2 to 17 at all income levels have computers, with 52% of those connected to the Internet. Most kids use computers to play games (some for 30 hours or more a week), and many teenage girls think nothing of rushing home from school to have e-mail chats with friends they have just left.
What’s clear is that, whether we like it or not, the Internet is an ever growing part of our lives and there is no turning back. “The Internet is just 20% invented,” says cyber pioneer Jake Winebaum. “The last 80% is happening now.”

Any foreigner who has tried to learn Chinese can tell how hard it is to master the tones required to speak and understand. And anyone who has tried to learn to play the violin or other instruments can report similar challenges.
Now researchers have found that people with musical training have an easier time learning Chinese. Writing in the online edition of Nature Neuroscience,researchers from Northwestern University say that both skills draw on the same parts of the brain that help people discover changes in pitch(音调).
One of the study’s authors,Nina Kraus,said the findings suggested that studying music “actually tunes our sensory system”.This means that schools that want children to do well in languages should hesitate before cutting music programs,Dr.Kraus said. She said music training might also help children with language problems.
Mandarin(普通话)speakers have been shown to have a more complex encoding(编码) of pitch patterns in their brains than English speakers do. This is because in Mandarin and other Asian languages,pitch plays a central role. A singlesyllable word can have several meanings depending on how it is intoned.
For this study,the researchers looked at 20 nonChinese speaking volunteers,half with no musical background and half who have studied an instrument for at least six years.
As they were shown a movie,the volunteers also heard an audio tape of the Mandarin word “mi” in three of its meanings:squint,bewilder and rice. The researchers recorded activities in their brain stems to see how well they were processing the sounds. Those with a music background showed much more brain activities in response to the Chinese sounds.
The lead author of the study,Patrick C.M.Wong,said it might work both ways. It appears that
native speakers of tonal languages may do better at learning instruments.
When learning Chinese,a foreigner will find ________.
A.he has a difficult time learning music at the same time |
B.he has an easier time learning music at the same time |
C.it is hard to master the tones required to speak and understand |
D.it is easy to use the brain to help him discover changes in pitch |
Why does Chinese learning have something to do with music training?
A.Because there is the same difficulty in learning Chinese and music. |
B.Because skills to learn the two make use of the same parts of the brain. |
C.Because music training might help people with language study. |
D.Because people who do well in Chinese study do well in music. |
The underlined word “intoned” in the fourth paragraph can be replaced by the word “____”.
A.created | B.spelled |
C.seemed | D.pronounced |
What would be the best title for this passage?
A.Mandarin Speakers Are Smarter than English Speakers |
B.Skilled Ear for Music May Help Language Study |
C.Pitch Plays a Central Role in Chinese Learning |
D.Schools Need to Develop Music Programs |
A few years ago I asked my children’s governess, Julia Vassilyevna, to come into my study.
“ Sit down, Julia Vassilyevna,” I said.“Let’s settle our accounts. Although you most likely need some money, you stand on ceremony and won’t ask for it yourself. Now then, we agree on thirty rubles a month…”
“ Forty.”
“ No, thirty. I made a note of it. I always pay the governess thirty. Now then, you’ve been here two months, so…”
“ Two months and five days.”
“ Exactly two months. I made a specific note of it. That means you have sixty rubles coming to you. Subtract nine Sundays… you know you didn’t work with Kolya on Sundays, you only took walks. And three holidays…”
Julia Vassilyevna flushed a deep red and picked at the flounce of her dress, but--- not a word.
“ Three holidays, therefore take off twelve rubles. Four days Kolya was sick and there were no lessons, as you were occupied only with Vanya. Three days you had a toothache and my wife gave you permission not to work after lunch. Twelve and seven---nineteen. Subtract…that leaves…hmm…forty-one rubles. Correct?”
Julia Vassilyena’s left eye reddened and filled with moisture. Her chin trembled; she coughed nervously and blew her nose, but---not a word.
“ Around New Year’s you broke a teacup and saucer: take off two rubles. The cup cost more, it was an heirloom, but---let it go. When didn’t I take a loss? Then, due to your neglect, Kolya climbed a tree and tore his jacket: take off ten. Also due to your heedlessness the maid stole Vanya’s shoes. You ought to watch everything! You get paid for it. So, that means five more rubles off. The tenth of January I gave you ten rubles…”
“ You didn’t ” whispered Julia Vassilyevna.
“ But I made a note of it.”
“ Well…all right.”
“ Take twenty-seven from forty-one ---that leaves fourteen.”
Both eyes filled with tears. Perspiration appeared on the thin, pretty little nose. Poor girl!
“ Only once was I given any money,” she said in a trembling voice, “ and that was by your wife. Three rubles, nothing more.”
“ Really? You see now, and I didn’t make a note of it! Take three from fourteen… leaves eleven. Here’s your money, my dear. Three , three, three, one and one. Here it is!”
I handed her eleven rubles. She took them and with trembling fingers stuffed them into her pocket.
“ Merci,” she whispered.
I jumped up and started pacing the room. I was overcome with anger.
“ For what, this ---‘merci’?” I asked.
“ For the money.”
“ But you know I’ve cheated you, God’s sake---robbed you! I have actually stolen from you! Why this ‘merci’?”
“ In my other places they didn’t give me anything at all.”
“ They didn’t give you anything? No wonder! I played a little joke on you, a cruel lesson, just to teach you … I’m going to give you the entire eighty rubles! Here they are in an envelope all ready for you… Is it really possible to be so spineless? Why don’t you protest? Why be silent? Is it possible in this world to be without teeth and claws--- to be such a nincompoop?”
She smiled crookedly and I read in her expression: “ It is possible.”
I asked her pardon for the cruel lesson and , to her great surprise, gave her the eighty rubles. She murmured her litter “merci” several times and went out. I looked after her and thought: “How easy it is to crush the weak in this world!”When the employer called Julia Vassilyevna in to talk with him, what he really wanted to do was _______

Being sociable looks like a good way to add years to your life. Relationships with family, friends, neighbours, even pets, will all do the trick, but the biggest longevity (长寿) boost seems to come from marriage or an equivalent relationship. The effect was first noted in 1858 by William Farr, who wrote that widows (寡妇)and widowers were at a much higher risk of dying than their married peers. Studies since then suggest that marriage could add as much as seven years to a man’s life and two to a woman’s. The effect holds for all causes of death, whether illness, accident or self-harm.
Even if the odds are stacked against you, marriage can more than compensate. Linda Waite of the University of Chicago has found that a married older man with heart disease can expect to live nearly four years longer than an unmarried man with a healthy heart. Likewise, a married man who smokes more than a pack a day is likely to live as long as a divorced man who doesn’t smoke. There’s a flip side, however, as partners are more likely to become ill or die in the couple of years following their spouse’s death, and caring for a spouse with mental disorder can leave you with some of the same severe problems. Even so, the odds favour marriage. In a 30-year study of more than 10,000 people, Nicholas Christakis of Harvard Medical School describes how all kinds of social networks have similar effects.
So how does it work? The effects are complex, affected by socio-economic factors, health-service provision, emotional support and other more physiological (生理的) mechanisms. For example, social contact can boost development of the brain and immune system, leading to better health and less chance of depression later in life. People in supportive relationships may handle stress better. Then there are the psychological benefits of a supportive partner.
A life partner, children and good friends are all recommended if you aim to live to 100. The ultimate social network is still being mapped out, but Christakis says: “People are interconnected, so their health is interconnected.”William Farr’s study and other studies show that _________.
A.social life provides an effective cure for illness |
B.being sociable helps improve one’s quality of life |
C.women benefit more than men from marriage |
D.marriage contributes a great deal to longevity |
Linda Waite’s studies support the idea that _________.
