United States health officials are urging people to stop using electronic cigarettes, known as e-cigarettes. The call to action came after such products were linked to health problems. Five deaths have also been reported. E-cigarettes are a popular substitute for smoking products. The electronic devices heat liquid that includes flavoring, nicotine and other chemicals into vapor—very small particles that users breathe in. Nicotine is found in many plants, including tobacco. E-cigarettes or similar devices also can provide THC or other substances to users. THC is the natural chemical present in marijuana(大麻) plants that gives users the mental state known as a “high”.
E-cigarettes are said to be safer than normal cigarettes because they do not create the cancer-causing byproducts of burning tobacco.Yet health officials say e-cigarette users have reported shortness of breath and other breathing problems, such as coughing and chest pain. Some have been sick to the stomach, felt very tired, suffered weight loss or developed high body temperatures. One report noted that most of the 53 illnesses reported in Illinois and Wisconsin were related to THC vaping(气化) products. But nearly 20 percent of the patients inhaled(吸入)substances like nicotine from e-cigarettes. Most of the reported cases were of young men.
The report found that, “Since no single product or substance has been associated with the illness, persons should consider not using e-cigarettes while this investigation is ongoing.” Last November, The Centers for Disease Control and Prevention, or CDC, reported that “e-cigarette use increased considerably among U.S. middle and high school students during 2017—2018.” Among high school students, it found e-cigarette use rose from 220,000 students in 2011 to 3.05 million in 2018.
On Monday, the Food and Drug Administration, or FDA gave a warning to JUUL Labs, maker of the best-selling e-cigarettes. The FDA accused the company of illegally marketing its products as being “safer than cigarettes” without the agency's approval.In a statement, the FDA's acting commissioner said that, “JUUL has ignored the law, and has made some of these statements in school to our nation's youth.” A JUUL spokesman said the company is studying the FDA's comments and “will fully cooperate”.
1.Which of the following can best describe e-cigarettes?
A.Deadly. B.Harmless.
C.Infectious. D.Effective.
2.What change will be caused when smokers inhale e-cigarettes containing THC?
A.They will be healthier.
B.They will lose weight.
C.They will feel excited.
D.They will be peaceful.
3.What information about JUUL Labs can we get from the last paragraph?
A.Students became its main marketing targets.
B.FDA didn't agree on its way of promoting its products.
C.It completely denied what it was accused of.
D.E-cigarettes were invented by it.
4.What can be the best title of the passage?
A.Say “No” to cigarettes
B.A sharp rise of e-cigarettes use among young people.
C.Safer e-cigarettes are needed for health.
D.E-cigarettes—a potential killer.

United States health officials say an estimated 80,000 people died of influenza (流感) and problems resulting from the flu last winter, making it the worst season since 1977. The director for the U.S.Centers for Disease Control and Prevention (CDC) reported the number to The Associated Press. Health experts were expecting the winter of 2017-2018 to be a bad year for flu deaths, but not that.
Doctor William Schaffner is an expert on vaccines, at Vanderbilt University in Tennessee. Schaffner noted that 80,000 deaths are nearly twice as much as what health officials once considered a “bad year”.
CDC officials say that between 12,000 and 56,000 Americans die every year from flu-related causes, but they do not have an exact count of how many people die from the flu each year. Influenza is a relatively common disease and not always listed on death records as the official cause of death. While last winter was a bad flu season in the U.S., it was not the worst. The 1918 flu lasted nearly two years. Historians estimate that the disease was to blame for between 500,000 to 700,000 deaths during that period. The exact number is still not known.
One thing that made the 2017-2018 flu season so bad was that the flu virus was strong. Usually the disease kills the very young, the very old or those who are already sick. However, last winter, the flu killed many healthy Americans. Another thing that made the flu season so deadly was that the flu vaccine was not as effective as experts had predicted. Drug makers have made changes to the vaccine. Even though the vaccine did not work well last year, health experts still strongly suggest getting vaccinated.
1.What can we learn about influenza in the first paragraph?
A.The winter of 2017-2018 saw the deadliest flu in history.
B.Effective cures should be found to deal with influenza.
C.Health experts had assumed flu would be severer.
D.More people died of influenza than expected in the winter of 2017-2018.
2.How many deaths did the health officials expect in a bad year?
A.80,000. B.40,000.
C.60,000. D.20,000.
3.Why can't CDC officials give an exact number of deaths from flu?
A.Because flu is always considered as a common disease.
B.Because people usually don't take flu seriously.
C.Because CDC officials are unwilling to count the deaths.
D.Because flu is not always listed on death records.
4.What do experts recommend people to do in the last paragraph?
A.Change the vaccine. B.Avoid using vaccine.
C.Get vaccinated. D.Do research on vaccine.

According to the United States government, people are classified as homeless if they have no place to stay and no expectation of finding a place for the next thirty days．Although technically accurate, that is an impersonal assessment of an enormous and very human problem．
The homeless population represents all of us Americans．It includes men and women, the elderly, children, and infants．Its members are from all ethnic groups．What they have in common is poverty．
Currently in the U．S．, thirty-nine million people live in poverty．When money is really tight, paying the rent or buying food often becomes a choice．Government assistance in the form of food stamps does help but, as one homeless man explains, you can’t pay the rent with food stamps．
With no money for rent, the streets and homeless shelters become the alternative．
Although men constitute the largest group within the homeless population, homeless women with children are rapidly joining them．In fact, one quarter of the homeless people in the U．S．are teenagers and young children．
People may become homeless for numerous reasons．However, there are certain factors that many of these individuals have in common．They include a lack of adequate education and job skills．A majority of the teenagers and adults have not completed high school．
The abuse of alcohol and drugs is also a common factor．One third of the adult homeless population abuses alcohol．While one quarter of the same group uses drugs．
Some members of this population suffer mental health problems．Within the past several years many institutions for the mentally ill have been closed and their patients sent “home”．Unfortunately, a number of those people have no home to go to and they are unable to adequately look after themselves．
Job loss in today’s economy has also become a real factor in the loss of people’s homes．The breakup of families through abandonment and divorce are also contributing factors, particularly when there are children involved．The parent who is left to care for the kids with inadequate income may be forced to depend on the homeless shelters to put a roof over their heads．

The United States Postal Service(LISPS)is offering a way to people who are interested in seeing tomorrow’s mail today．The postal service will send consumers images(图像)of their letters，magazines and other mail before they arrive．The new service is called Informed Delivery．It is an attempt to remain competitive in an ever—changing world．
Postal service officials say the increased use of email，digital messaging services and social media has made it difficult to stay relevant．David Rupert is a media relations specialist who spoke about the competition the agency now faces．Whether you turn on a television or your computer，or people come to your door with different products and services，all of those are competing for consumers’time and energy，he said．
Interested users are first required to sign up for Informed Delivery．Once registered，the consumer receives a daily email with virtual(虚拟)images of letters or other things to be delivered．The US Postal Service says it can especially help those who have a mailbox at their local post office，so they know when to get their mail：
Another postal offering is a service that seeks to make advertising-related mail-often called junk mail—more fun．The service uses virtual and augmented reality(虚拟现实和增强现实)to let consumers interact with their junk mail．Many companies put special coding on their advertising，which can give users an interactive experience．Some companies even put virtual reality eyeglasses in the mail to make their ads come to life．Consumers have mixed reactions to virtual and augmented reality advertising．“You can find some good things within junk mail．It is a good idea．We’11 see how it works，”Postal service user Victor Teah said．But Jocelyn Coatney doesn’t think it would change her mind about junk mail．“For some，that might be fun．But for me，it would be useless，”she said．

People in the United States have many ways to get news, some of which are available 24 hours a day. In a recent survey（调查）, about 15 percent of American interviewees said that they spend less than one-half to two hours per day watching, listening to, or reading the news. News comes from every source, not only from printed ways, but from TV, radio, and the Internet as well.
With the increased availability of news, serious questions have been raised about the role of the news media in society. Should the media report every detail about every story, even when the information does not seem timely or valuable? Some researchers are concerned that by focusing on everything at once, the media increasingly ignore the more important social, political and economic problems that we face. We cannot concentrate on what’s important by reading about what is not. One extreme example of this is the type of information covered by the tabloid（小报）media, which focus on negative stories of violence and crime.
How can people deal with all the news that is available to them? Some become “news resisters” and choose to turn their backs on news, resisting their desire to turn on the TV and read the paper every day. They argue that although daily news reports may provide us with many facts, they do not include the background or some information that we need to understand news events. They suggest that, instead of daily reports, we look for information that has more in-depth analysis of the news, such as monthly magazines.
1.What percentage of the interviewees spend less than one half to two hours per day paying attention to the news? (within 3 words)
2.According to the researchers, what is the disadvantage of news media? (within 6 words)
3.How do you describe tabloid media? (within 5 words)
4.Who are “news resisters”? (within 9 words)
5.What information does “news resisters” look for? (within 2 words)

People back in the United States are always asking me, “What's it like to live in China?” They hope to hear strange stories about weird food and cultural conflicts. Instead, I tell them that living in China is like being a baby.
Please don’t misunderstand me. I don’t think that Chinese people are babies. I am a baby. Or at least, I become one when I leave my house. That’s because babies can’t read, and when I leave my house in Beijing, I’m illiterate (不识字的).
This can be dangerous. If a sign says, “Watch out for big angry bears,” in Chinese, I will continue walking, completely ignorant of my peril (危险). Then a bear will eat me for breakfast.
I have started to recognize a few characters, but they seem impossible to ever learn without a lifetime of study. When I see a character I like. I give it a name. There is “The Square,”“The Octopus(章鱼) ,”“The-upside-down Octopus,” and my favorite, “Upside-down Octopus on an airplane.” However, I still don't know their sounds or meanings.They are just beautiful mysteries to my eyes.
Because I can’t read, city streets present an endless series of enigmas. If I see a business, I wonder, “Is that a restaurant? A dentist? A lawyer’s office?” Once, while hungry, I saw a big colorful sign. I walked in and asked a realtor (房屋中介) to see the drink menu.
Speaking of menus, eating at restaurant is a daily misadventure. Many places have photos of food, which is helpful. But if they have no photos, I walk from table to table and point at whatever looks delicious. I apologize if I’ve ever interrupted your dinner to point at your plate. I didn’t mean to be rude. I was just a hungry baby!
1.Why does the author think living in China is like being a baby？ ______
A.Some Chinese people behave like babies.
B.It’s comfortable to be a baby in China.
C.He is as curious as a baby about Chinese things.
D.He is like a new-born who can’t read at all.
2.What do we know about the author？ ______
A.He can order food in simple Chinese.
B.He doesn't know many Chinese Characters.
C.His spoken Chinese is better than his written Chinese.
D.He memorizes Chinese words based on their sounds.
3.In Paragraph 5, what does the underlined word “enigmas” mean？ ______
A.Stories.
B.Miracles.
C.Choices.
D.Puzzles.
4.What is the passage mainly about？ ______
A.The author’s love for Chinese food.
B.The language barrier the author meets in China.

In the United States you will find yourself being urged from every page of every newspaper and every television station to buy all kinds of goods.
Not only is there a wide range of prices for goods in America, there is also a wide range in the quality of goods offered for sale. Unlike some countries,
Americans generally pay the price of a product without question, instead of trying to get a lower price by bargaining. However, there are many “sales” in the United States, during which time stores will lower their normal prices. This may all be very confusing to visitors. How are you going to know how to “get your money’s worth” when you shop? Perhaps the best advice is: Don’t hurry. Visit various stores and determine the quality of goods. Read the advertisements so that you can compare prices.
There is a great variety of shops in the United States, ranging from very large stores called “department stores” to very small shops. There are “discount houses” offering goods at low prices, and “dime stores” specializing in a wide range of inexpensive items.
Most department stores in large cities carry better quality products at higher prices. However, they offer the shoppers great convenience since they contain such a wide variety of products.
If convenience isn’t as important to you as price, you may want to shop in discount houses. These stores have nearly as great a variety of goods as department stores, but offer lower prices. They can do so for several reasons. They don’t offer the same services to buyers that department stores do; there may be fewer sales people; and the store probably doesn’t deliver purchases.
Another popular shop is the “dime store”. No longer selling many things for five or ten cents, these stores got their name in the last century when it was decided that a small profit on a great quantity of goods would be better than a large profit on fewer sales. Dime stores specialize in a wide variety of inexpensive items and today, prices range from a quarter or 50 cents up to several dollars.
1.The passage is mainly about______
A. American hospitality. B. the life of Americans.
C. American stores. D. the business of Americans.
2. Why can discount houses offer goods at lower prices compared with department stores?
a. They have fewer employees.
b. They have larger quantities of goods.
c. They offer fewer services.
d. They don’t provide delivery service.
A. a b c B. a b d C. a c d D. b c d
3.What’s special about dime stores?
A. They sell lots of goods at a small profit.
B. They make big profits by selling some goods.
C. They provide goods with a price lower than 50 cents.
D. They provide goods ranging from bargains to expensive ones.
4.Where can we most probably read this passage?
A. In a research paper. B. In a science report.
C. In a geography book. D. In a travel magazine.
