Last month we visited Perth, the biggest city in Western Australia, and went to a wild flowers’ exhibition. There we saw a large number of wild flowers we had never seen before. We had a wonderful time. Perth is famous for its beautiful wild flowers. In spring every year Perth has the wild flowers’ exhibition. After visiting Perth, we spent the day in the countryside. We sat down and had a rest near a path at the foot of a hill. It was quiet and we enjoyed ourselves. Suddenly we heard bells ringing at the top of the hill. What we saw made us pick up all our things and run back to the car as quickly as we could. There were about three hundred sheep coming towards us down the path.

America is a mobile society. Friendships between Americans can be close and real, yet disappear soon if situations change. Neither side feels hurt by this. Both may exchange Christmas greetings for a year or two, perhaps a few letters for a while — then no more. If the same two people meet again by chance, even years later, they pick up the friendship. This can be quite difficult for us Chinese to understand, because friendships between us flower more slowly but then may become lifelong feelings, extending (延伸) sometimes deeply into both families.

Americans are ready to receive us foreigners at their homes, share their holidays, and their home life. They will enjoy welcoming us and be pleased if we accept their hospitality (好客) easily.

Another difficult point for us Chinese to understand Americans is that although they include us warmly in their personal everyday lives, they don’t show their politeness to us if it requires a great deal of time. This is usually the opposite of the practice in our country where we may be generous with our time. Sometimes, we, as hosts, will appear at airports even in the middle of the night to meet a friend. We may take days off to act as guides to our foreign friends. The Americans, however, express their welcome usually at homes, but truly can not manage the time to do a great deal with a visitor outside their daily routine. They will probably expect us to get ourselves from the airport to our own hotel by bus. And they expect that we will phone them from there. Once we arrive at their homes, the welcome will be full, warm and real. We will find ourselves treated hospitably.

For the Americans, it is often considered more friendly to invite a friend to their homes than to go to restaurants, except for purely business matters. So accept their hospitality at home!

We all like watching online videos of dogs and cats doing funny things. But if you had to decide, which of the two animals would you say you might like better? Your answer may say something about your personality.

According to a 2010 study led by Sam Gosling, a scientist at the University of Texas, US, dog people are about 15 percent more outgoing and 13 percent more pleasant to be friends with than cat people.

This is not hard to understand, since cats and dogs behave differently themselves. “Cats will occasionally engage in social activities, but usually after only a few minutes, they will abandon the game. Dogs, on the other hand, will often engage in play, like fetching a thrown ball, for hours at a time,” said Modern Dog Magazine.

Although cat people are less social, Gosling’s study showed that they are 11 percent more open-minded than dog people. They usually like art, adventures and unusual ideas. They also have more imagination and curiosity. But dog people are more likely to stick to old beliefs and traditional interests.

However, their love of a free lifestyle also means that cat people dislike making plans. They just follow whatever ideas pop into their heads without planning ahead. But dog people are different. They usually have strong self-control and like to carry out their plans.

Despite these big differences between dog people and cat people, there are some things that they have in common, “Both types of people consider themselves close to nature, dislike animal-print clothing, and are generally optimists,” noted Mother Nature Network.

But can personality change? Can a cat person become a dog person, or the other way around? In a study done by Stanley Coren, a scientist based in Canada, he asked cat owners: “If you had enough living space and there were no objections form other people in your life, and someone gave you a puppy as a gift, would you keep it?”

About 68 percent of them said they would not accept a dog as a pet. But when dog owners were asked the same question about a kitten, almost 70 percent said they would allow a cat into their lives.

1.According to the article, dog people _____________ cat people.

A. perform better in school than B. are more open-minded than

C. have closer friends than D. are more traditional than

2.The underlined phrase “engage in” in Paragraph 3 probably means_____________.

3.What do cat people and dog people have in common?

A. Both of them like planning ahead

B. Both of them love travelling and adventures

C. Both of them are imaginative and curious

D. Both of them care about nature.

4.What can we conclude from the last two paragraphs?

A. Cat people are more likely to become dog people.

B. Dog people are more likely to accept cats into their homes than cat people are to accept dogs.

C. Neither dog nor cat people like to accept a new pet.

D. It is difficult to find out whether dog people or cat people will make a change.

If you see someone drowning, speed is very important. Once you get him out of the water, if he isn’t breathing, you have four minutes before his brain is completely destroyed. Support his neck, tilt（使翘起）his head back and press his chin（下巴）upwards. This stops the tongue blocking the airway in the throat and is sometimes enough to get him breathing again. If that doesn’t work, start mouth-to-mouth breathing. Press his nostrils（鼻孔）together with your fingers. Open your mouth and take a deep breath. Blow into his lungs until his chest rises, then remove your mouth and watch his chest fall. Repeat twelve times a minute. Keep doing until help arrives.

To bring a child back to life, keep your lips around his mouth and nose and gently blow into his mouth. Give the first four breaths as quickly as possible to fill the blood with oxygen. If, in spite of your efforts, he starts turning a blue grey color, you can feel no pulse（脉搏）,then pressing is the last chance of saving his life.

With arms straight, rock（摇动）forwards, pressing down on the lower half of the breastbone. Don’t be too hard or you may break a rib（肋骨）. Check how effective you are seeing if his color improves or his pulse becomes independent to your chest pressing. If this happens, stop the pressing. Otherwise continue until rescue arrives.
