Do yooften feel that yohaven’t afford got enough time to carry out all the plans drawn up at the beginning of the year, and a new year is drawing near unexpectedly? If yohave the same feeling, yoare not alone. It feels like time speeds up every year.

Scientists claim that over thousands of years, great changes have taken place. However, time is mysterious and unique. No matter what happens in the world, time seems to turn a blind eye to the outside world. Whether it is in the past, at present, or in the future, time would not vary with the development of the world. It remains the same and operates at a relatively steady speed.

According to a recent study, smart phones，tablets and other digital products have trained our brains to process more information, causing us to think time is passing faster than it really is. Even just reading a simple advertisement on the digital device, the people who were experimented on thought time passed more quickly, compared with the other group that read a long monologue(独白)from a real book.

“It’s almost as though we’re trying to keep step with the technology, and do things more quickly and more efficiently,” Dr. Mcoughlin from James Cook University said.“It seems like there’s something about technology itself that speeds up our pacemakers which measure the passing of time.”

Researchers note that in order to stop time from rushing by, we should reduce the time spent online and prevent the pacemaker moving fast .The findings prove what most people have known: we need to stop and smell the roses.

25. Which of the following is TRUE according to the scientists?

A. People have known clearly about time. B. Time is something that never changes.

C. People can change the feature of time. D. Time usually keeps pace with our life.

26. What makes us feel that time is getting faster?

A. The healthy lifestyle. B. Reading a lot of books.

C. The high tech products. D. The development of the brain.

27. What's the attitude of Dr. McLoughlin to the study?

A. Opposed. B. Approving. C. Doubtful. D. Unconcerned.

28. By saying "we need to stop and smell the roses", the author means_________.

A. we must know how to plant roses

B. it's necessary to avoid using the Internet

C. people can keep working without a break

D. we should learn to slow down and enjoy our life. C

There are several reasons why cats climb trees, mostly to do with defensive purposes. Cats, as predators(捕食者)，like to understand their environment well. Cats climb trees to get a better view or their surroundings, to help them see any potential dangers or potential prey(被掠食者).

While cats are predators, they can also be easily attacked by larger animals. A tree often provides a safe hiding place. In the wild, cats climb up trees to give them a resting place that is out of predators’ range. It also helps disguise their presence, which can prevent any prey from noticing that there is a cat nearby.

Sometimes some cats may climb trees for fun, or possibly to work on improving their climbing abilities. Kittens frequently test out their claw skills by trying to climb up everything, from bookcases to trees to a person’s leg. Climbing practice is good for cats; it can improve their strength and flexibility and teach them an important defensive skill. To prevent them from practicing indoor climbing of your furniture, however, owners may wish to buy a carpeted cat tree for climbing.

If a cat has gotten up a tree and cannot get down, the owner may wonder why its remarkable climbing abilities only work in one direction. A cat’s claws curve(弯曲)inward, allowing it to take hold of surfaces while going up head first. Unfortunately, this useful climbing curve does nothing to help the animal get back down again. Eventually, most trapped kittens will either jump out of the tree or realize that they can get down by going tail first. Either way, a cat up a tree is usually nothing to panic about unless it is injured; they are intelligent animals and will find out how to get down sooner or later.

29. In most cases, cats climb trees in order to

A. have fun B. seek food

C. defend themselves D. please their owners

30.What does the underlined word “disguise” in Paragraph 2 mean?

A. Find out B. Focus on

C. Make clear D. Cover up
