【题目】 When I was very young, I wanted to become a veterinarian (兽医) one day, because I loved animals very much, especially dogs. But it was a pity that there was no room in my adult life for a dog. Then, last year, I could not believe that I developed cancer (癌症). I wanted to keep a dog, but I knew my illness made it impossible for me to keep one.

And I have been spending more time caring about him, taking long walks with him in the park.

【题目】 Can dogs and cats get along well in the same home? People are thinking about getting a dog for their cat as a friend, but they are worried about that the dog and the cat will fight. A recent research has found that if the cat is taken back home before the dog, and if they are introduced when they are still youngless than 6 months for cats, a year for dogs, it is possible that the two pets will get along swimmingly. In two-thirds of the homes cats and dogs have a good relationship(关系).

However, there was something unfriendly between the cat and dog in 25% of the homes, while aggression(侵略, 好斗)and fighting were found in 10% of the homes. One reason for this is probably that some of their body languages are just different. For example, when a cat turns its head away, it means aggression. while a dog doing the same means submission(顺从).

In homes with cats and dogs living in peace, researchers found a surprising behavior(行为). They are learning how to talk each other’s language. It is a surprise that cats can learn how to talk "Dog", and dogs can learn how to talk"Cat".

The interesting thing is that both cats and dogs seem to become smarter. They can learn to read each other's body languages, suggesting that the two may have more in common(共同的)than was expected(预料). If they understand each other's body language very well, cats and dogs can play together, and enjoy sleeping together on the sofa.

The importance of this research on cats and dogs may go beyond(超过)pets—to people who don't get along well, including neighbours, workmates at work, and even countries. If cats and dogs can learn to get along, surely people have a good chance.

1The underlined word swimmingly in Paragraph 1 is closest in meaning to ______.

A.早早地B.主要地C.迅速地D.顺畅地

2Some cats and dogs may fight when ______.

A.they are cold to each otherB.they look away from each other

3What can people find surprising about cats and dogs?

A.They eat and sleep together.B.They watch each other's behaviors.

C.They learn to speak each other's language.D.They know something from each other's voices.

4In Paragraph 4 we can learn that cats and dogs ______.

A.have common interestsB.are less different than was thought

C.have a common body languageD.are not so smart as was expected

5What can we learn from cats and dogs?

A.We should learn to get along well with others.B.We should know more about animals.

【题目】Read the passage and fill in the blanks with proper words(在短文的空格内填入适当的词,使其内容通顺,每空格限填一词,首字母已给)

I don’t believe it! It’s 11p.m. and I’m still sitting here writing this article for the school magazine !I’ve had two weeks to write it and my teacher wants it tomorrow . She’s always c1 that I leave things to the last minute. Maybe she’s right. A month ago, I made up my mind to be more efficient this year and not to leave thing to the last minute. But I’ve failed. I’ve also been trying to get fitter for four weeks now. I’ve started going to the gym. I’ve taken up karate lessons and I’ve changed my diet. I’ve even been going to bed earlier. But I’m not feeling any fitter. I felt just a little u2. I miss my bad habits. Why is leading a better life so hard?

I’ve just read an article on a website and I’ve found out that it isn’t my fault! In fact, it isn’t anyone’s fault! It’s our brains. They’re programmed, therefore, it is difficult to break bad habits. There’s nothing we can do . Scientists have done experiments that show we use one part of our brain when we think about o3and another when we think about other people. However, when we think about the ‘future us’, we use the part of the brain that we usually use to think about other people. In other words, the brain sees the ‘future you’ as a different person to your ‘present you ’. And that’s why we don’t always find it easy to make sensible d4 in the future when we face difficulties.

But that’s not all. Scientists have also found out that it takes around ten weeks to form a good habit. For example , if I want to keep fit, it’s going to take me ten weeks to go to the gym and then it will become an automatic part of my life. That’s because ten weeks is the amount of time the brain needs to change and a5new ways of behavior as a part of everyday life. The good news is that once you make it to ten weeks, everything becomes much easier. The bad news is that ten weeks is a really long time, so it’s easy to give up on (打消)your good plan s6

So there you are. Maybe we want to change our ways and become better people but our brains won’t let us . or is this just an e7? Look! I’ve finished my article on time. Anything is possible!
