If you have a cat, you already know that a cat isn’t a dog that doesn’t have to be walked. If you’re about to bring a cat into your family, you need to understand that basic fact. The common wisdom is that dogs are friendlier than casts.
In recent years, scientists who have done DNA studies have offered a better way to understand cats. Unlike other animals that people feed, cats domesticated themselves, and, in a way, trained humans. Cats decided to live close to humans because doing so benefited the casts themselves.
Studies show that cats have lived with humans for about 12,000 years, since people first settled down and started farming. When people started storing grain, mice arrived and started eating the grain. Clever cats figured out that mice settlements where people stored grain were easy for hunting, so they started hanging around. Cats did what they needed to do to get the people to let them stay, but they kept up their independence. Over time, cats allowed humans to get a bit closer to them. Later, the farmers did befriend the cats. Certainly, it didn’t do them any harm because they could see the cats were really helping them out by eating mice.
Today, about a third of American families have cats. In most of those homes, the cats are still more interested in pleasing themselves than in pleasing their human families. A dog may do anything it can to make you happy, but kitty will teach you to make kitty happy.
1.Compared with dogs, cats are______.
A. colder B. friendlier
C. more warm-hearted D. more frightening
2.According to the text, why do cats decide to stay close to humans?
A. To be useful to themselves B. To protect grain from mice
C. To rely on humans for food D. To keep up their independence
3.What may be the best title for the text?
A. A common point between dogs and cats
B. The reasons why people like dogs
C. A disadvantage of raising cats
D. The basic fact about cats.

If you’re reading this story, the chances are you’ve got a pretty good command of English. You’re not alone — an estimated 1.5 billion people speak English today, making it the most commonly used language in the world. Most are non-native speakers with English as their second language, while it serves as a third or fourth language for hundreds of millions more. So which place has the most fluent non-native English speakers?
According to a new report by international education company, the Netherlands is the best non-native English speakers across the globe. The results of its English Proficiency Index (英语能力指数), based on a free online test taken by 2.3 million volunteers, show that the Dutch are the most fluent. Sweden was positioned just below, with a score of 68.74 out of 100, while Norway came in third with 67.93 points.
Although the places with “very high proficiency” were largely made up of European countries, Singapore and South Africa also scored highly, coming in fifth and sixth place respectively.
The report also found that English was the most widely studied second language in the world by far. This may be the reason why just 20% of school students in the United States were studying a foreign language.
The survey was measured by testing non-native English speakers in 100 countries and over 400 cities and regions who voluntarily agreed to take the test. But there’s one thing that should be noticed. People are more likely to participate (参与) in the survey if they can surf the internet more easily. And this may greatly influence the accuracy (准确性) of the results.
1.Which of the following country has the most fluent non-native English speakers?
A.America. B.Singapore.
C.Sweden. D.The Netherlands.
2.What can we infer from Paragraph 4?
A.Americans do not need to learn a second language.
B.Americans dislike languages other than English.
C.More and more people are taking English as a second language.
D.Not many Americans would like to learn another language.
3.How was the survey carried out?
A.By asking volunteers to test online.
B.By handing out paper survey in some places.
C.By inviting volunteers to participate in the company.
D.By cooperating with other organizations.
4.What’s the attitude of the author towards the results of the survey?
A.Positive. B.Doubtful.
C.Supportive. D.Objective.

“If you talk to the plants, they will grow faster and the effect is even better if you’re a woman.” Researchers at Royal Horticultural Society carried out an experient to find that the voice of a woman gardener makes plants grow faster.
The experiment lasted a month and by the end of the study scientists managed to discover that tomato plants grew up two inches taller when women gardeners talked to them instead of male.
Sarah Darwin was the one making the plants registered the best growth. Her voice was the most “inspiring” for plants than those of nine other gardeners when reading a passage from The Origin of Species. The great-great-granddaughter of the famous botanist(植物学家) Charles Darwin found that her plant grew about two inches taller than the plant of the best male gardener.
Colin Crosbie, Garden Superintendent at RHS, said that the finding cannot yet be explained. He assumes that women have a greater range of pitch(音高) and tone(音调) which might have a certain effect on the sound waves that reach the plant. “Sound waves are an environmental effect just like rain or light ,”said Mr Grosbie.
The study began in April at RHS Garden Wisley in Survey. Scientists started with open auditions(听力) for the people who were asked to record passages from John Wyndham's The Day of the Triffids, Shakespeare’s A Midsummer's Night Dream and Darwin's The Origin of Species.
Afterwards researchers selected a number of different voices and played them to 10 tomato plants during a period of a month. Each plant had headphones(耳机) connected to it. Through the headphones the sound waves could hit the plants. It was discovered that plants that “listened” to female voices on average grew taller by an inch in comparison to plants that heard male voices.
Miss Darwin said, “I think it is an honor to have a voice that can make tomatoes grow, and especially fitting because for a number of years I have been studying wild tomatoes from the Galapagos Island at the Natural History Museum in London.”
1.What does the passage talk about?
A.Plants enjoy men’s voices than women’s. |
B.A botanical experiment in a museum. |
C.Voice’s influence on plant growing. |
D.Strange phenomenon(现象) at Royal Horticultural Society. |
2.What does the underlined sentence in paragraph 4 mean?
A.Plants need sound as well as rain and light. |
B.Sound is basic for the plant to grow. |
C.Sound has a good effect as rain or light does. |
D.Plants can’t live without sound, rain or light. |
3.Sarah Darwin is most likely a (an)_____.
A.botanist | B.gardener | C.astronomer | D.environmentalist |
4.What can we learn from the passage?
A.The experiment ended in May. |
B.Scientist can explain the findings clearly. |
C.Plants enjoy listening to the passages from masterpieces. |
D.The findings are of great importance to human beings. |
