How words came into being is unknown. All we assume (推测) is that some early men invented certain sounds，in one way or another，to express thoughts and feelings，actions and things，so that they could talk with each other. Later they agreed upon certain signs，called letters，which could be put together to show those sounds，and which could be written down. Those sounds，whether spoken or written in letters, are called words.
The power of words，then，lies in their associations—the things they bring up to our minds. Words become filled with meaning for us by experience；and the longer we live，the more certain words bring back to us the happy and sad events of our past；and the more we read and learn，the more the number of words that mean something to us increases.
Great writers are those who not only have great thoughts but also express these thoughts in words which have powerful effects on our minds and feelings. This clever use of words is what we call literary style (文体)．Above all，the real poet is a master of words. He can express his meaning in words which sing like music，and which by their position and association can move men to tears. We should therefore learn to choose our words carefully and use them correctly，or they will make our speech silly and common.We learn from the text that language might have begun with________.

The hottest“green”toy in Germany isn't made of organic or recycled materials.This one has a solar panel and only runs if kids remember to insert bright red “energy stones”that power the space station.Germany，a pioneer in many renewable energy initiatives，is also at the forefront of creating environmentfriendly toys aimed at making kids think about where energy comes from and how much of it they can use，raising awareness through play.A number of hightech green toys are on display at this year's Nuremberg toy fair，which runs through Sunday.
Among them，there are hydroelectricpowered(水电动力的)toy cars，and doll houses with wind turbines and rainwater catchers.The bright green “Future Planet”space station features an inner atrium(中庭)with a fan that is powered by a functioning solar cell.Its aim is to get kids to use their imagination about how energy will be created in the future.
Makers and retailers believe such toys will play an increasingly important role in their future—and that of our kids.“Energy is the question of the future and we are definitely thinking about this as we move ahead，”said Judith Schweinitz，a spokeswoman for Playmobil，maker of the solar panelfitted space station.“It is increasingly being brought into our play concept.”Green toys—which range from those made of sustainable materials to ones like the space station that just raise environmental awareness—make up only a sliver of the $ 84 billion international toy market，but their share is growing，studies indicate.Environmental research firm Earthsense，based in Syracuse，New York，predicts that green toys will account for about $ 1 billion，or 5 percent of U．S.toy sales in the next five years.Parents are smart and they want information about what's in the product.That's what's really driving the market.The hottest “green”toy in Germany is ________.

Americans gave nearly $300 billion away last year. Do you know the reason? Beyond the noble goals of helping others, it is that giving will make them happier.
It is a fact that givers are happier people than non-givers. According to the Social Capital Community Benchmark Survey, a survey of 30,000 American households, people who give money to charity are 43% more likely than non-givers to say they are “very happy” about their lives. Similarly, volunteers are 42% more likely to be very happy then non-volunteers.
The happiness difference between givers and non-givers is not due to differences in their personal characteristics, such as income or religion. Imagine two people who are identical in terms of income and faith, as well as age, education, politics, sex, and family circumstances, but one donates money and volunteers, while the other does not. The giver will be, on average, over 40 percentage points more likely to be very happy than the non-givers.
A number of studies have researched exactly why charity leads to happiness. The surprising conclusion is that giving affects our brain chemistry. For example, people who give often report feelings of euphoria, which psychologists have referred to as the “Helper’s High”. They believe that charitable activity produces a very mild version of the sensations people get from drugs like morphine and heroin.
Of course, not only does giving increase our happiness, but also our happiness increases the possibility that we will give. Everyone prefers to give more when they are happy. Researchers have investigated this by conducting experiments in which people are asked about their happiness before and after they participate in a charitable activity, such as volunteering to help children or serving meals to the poor. The result is clear that giving has a strong, positive causal impact on our happiness, so does happiness on givingAccording to Paragraph 2. We can learn that .
| A．only those people who gave money to charity will be happy |
| B．more givers say they feel having happy lives than non-givers |

Finding a friend doesn’t seem like a difficult job. However, bad friends are easier to find than good friends these days. If you’re sitting there and wondering if you have a bad friend, let me define it for you.
A bad friend is someone whose jealousies and insecurities outweigh their love for someone. They night want to be a good friend but they’re too messed up in their own head to ever actually do it. They wonder if their friends are going out without them or if they’re being forgotten and left behind. People who are violently insecure don’t have what it takes to be the quality of a friend.
Bad friends are narcissistic(自恋的).They look for any opportunity to bring the conversation back to them. Worse, they might not even be aware that they’re doing it. In their mind, they might think they are the best friend ever, which is truly frightening.
Bad friends are quick-change. They’re by your side when you’re fun and you have something to give them but as soon as you’re going through a difficult time, they will become indifferent quickly. They won’t bring you cold medicine. They won’t give you a ride to the doctor, everything they do is self-serving.
If you find a friend who has these same characteristics, send them to your bad friend list immediately. Your friends are supposed to be the solution to your problems, not the source.
I believe your twenties are a time when you need positive and helpful friends. In such a time, friendships aren’t easy to maintain like they once were in school. Now we actually have to put work into it, we have to make a conscious effort to keep the friendship going. You need to ask yourself, “Is this person worth it? Do they treat me like a fool or what?” if your have doubts, try to make them clear by considering the past experiences. Toxic(有毒的) friendships do nothing but drag you down. My point is that you have to take care of yourself and stop getting in touch with your bad friends. Only surround yourself with people who bring out the best qualities in you. It may sound cruel but it’s true,.The author believes that we can easily find a .

The deadliest Ebola(埃博拉病毒) outbreak in recorded history is happening right now. The outbreak is unprecedented(空前的) both in the number of people who have gotten sick and in the geographic scope. And so far it’s been a long battle that doesn’t appear to be slowing down.
Ebola is both rare and very deadly. Since the first outbreak in 1976, Ebola viruses have infected thousands of people and killed roughly killed 60 percent of them. Symptoms can come on quickly and kill fast.
The current outbreak started in Guinea sometime in late 2013 or early 2014. It has since spread to Sierra Leone and Liberia, including some capital cities. And one infected patient traveled on a plane to Nigeria, where he spread the disease to several others and then died. Cases have also popped up in various other countries throughout the world, including in Dallas and New York City in the United States.
The Ebola virus has now hit many countries, including Guinea, Liberia, Sierra Leone, Nigeria, Senegal, and the United States. The virus, which starts off with flu-like symptoms and sometimes ends with bleeding, has infected about 6,500 people and killed more than 3,000 since this winter, according to the World Health Organization on September 30, 2014.
There are some social and political factors contributing to the current disaster. Because this is the first major Ebola outbreak in West Africa, many of the region’s health workers didn’t have experience or training in how to protect themselves or care for patients with this disease.
Journalist David Quammen put it well in a recent New York Times article, “Ebola is more dangerous to humans than perhaps any known virus on Earth, except rabies(狂犬病) and HIV. And it does its damage much faster than either.”
Hopefully, researchers are working to find drugs, including a recent $50 million push at the National Institutes of Health. And scientists are working on vaccines(疫苗), including looking into ones that might be able to help wild chimpanzees, which are also susceptible to the disease. The first human Ebola vaccine trial is scheduled to start in the spring of 2015.According to the passage, which of the following about Ebola is true?
| A．The Ebola outbreak now is the biggest one in history. |
| B．Ebola breaks out quickly but it is under control now. |
| C．Ebola is deadly and common so it kills a lot of people. |
| D．Ebola killed about 60 thousand people quickly in 1976. |
The Ebola virus was brought to Nigeria by .
| A．a flying bird | B．an infected passenger |
| C．hot African weather | D．a health organization |
The symptoms of Ebola at the beginning are more like those of .
| A．flu | B．rabies |
| C．HIV/AIDS | D．internal bleeding |
The last paragraph mainly tells us that .
| A．it will be a huge waste when researchers spend lots of money finding a cure |
| B．the vaccines can be effective to wild chimpanzees but not to the humans |
| C．there will be an optimistic future in which we can defeat the disease |
| D．we can use the vaccine to cure the patients completely in 2015’s spring |
What is the best title of the passage?
| A．Ebola ---- The African Local Disaster |
| B．Ebola ---- The Newly-Found Disease |
| C．Ebola ---- A More Effective Vaccine |
| D．Ebola ---- The Deadly Virus Outbreak |
Liz had been bleeding for a long time! She was my closest professional colleague and good friend at the time when we worked in an IT company. It was her first day back at work after an operation and I thought she should have taken a few more days to recover.
Realizing that we couldn’t stop the bleeding, we headed to the emergency room and spent hours there waiting to be seen. After the treatment, I drove her to my apartment. I had to leave her in my apartment while I dashed off to take a final exam for a very important course I was taking. Upon my return, we decided Liz was in a good enough condition to sustain a trip back from my Northern Virginia apartment to her home in Maryland.
Although it was nearly midnight and we were both exhausted, we still decided to set off.
