If you have ever had a cat, or have watched one of the many funny cat videos online, you'll know that cats have a mind of their own. A lot of the things they do are hard to understand—they like to climb up tall furniture, fit themselves in small spaces and attack(攻击) small objects for no reason at all.
Now scientists have managed to work out what exactly is going on in the brains of our little friends. According to Tony Buffington, a professor at Ohio State University in the US, cats' strange behavior(行为)largely comes from their way of life back in the wild. "Cats today still have many of the same natural abilities that allowed them to live in the wild for millions of years." he said in a TED Talk. "To them, our homes are their jungles(丛林)."
Cats' bodies and great balancing(平衡)abilities allow them to climb to high places to better look at the environment. Even though they don't have to hunt(猎食)any more in human houses, they still keep the old habit of observing the living room from, for example, the top of the fridge.
Cats' hunting abilities also make them attack small things like keys and USB drives.
In the wild, they hunt whatever they can get for food, and most of the animals they kill are small. However, a cat can also be prey. This explains why they like to stay in small spaces like drawers or washing machines—they are hiding, or they think they are hiding, from more dangerous animals. This is also why cats prefer a clean box: a dirty one with an unpleasant smell could easily show enemies where they are.
Knowing how cats' minds work is not only useful for better understanding them, it may also help cats' owners to better meet cats' needs. For example, owners could try to make climbing easier for cats by moving their furniture around. They could also use "food puzzles" to make eating feel more like hunting instead of just giving food to the cats.
1.According to the passage, Tony Buffington agrees that ________.
A.cats' strange behavior is hard for people to understand
B.cats are more used to living in the wild than in humans' homes
C.cats' natural abilities are still helpful to make them get food today
D.cats act strangely mainly because of their natural abilities in the wild
2.The word "prey" in Paragraph 4 probably means"________".
A.an animal that lives in the jungles
B.an animal that likes keeping itself clean
C.an animal that likes playing hiding games with people
D.an animal that becomes others' food after being hunted
3.According to the writer, cats' owners can better meet cats' needs by ________.
A.creating hunting games at home B.giving them delicious food
C.making them go back to the wild D.putting them in the furniture
4.What is the writer's main purpose in writing this passage?
A.To describe cats' past wild experience to readers.
B.To tell cat owners how to make life easier for cats.
C.To explain the reasons behind cats' strange behavior.
D.To compare cats' behavior in human homes with that in the wild.

Have you ever watched a film with your friends and thought, “How wonderful!” or had a meal with your family and said, “That’s was the best!”?
Well, there may be a small secret(秘密)about why you enjoyed it so much. Our experiences are stronger if we share them with someone. That means good experiences become better, and bad ones become worse. That’s according to a new study by Yale University.
Scientists did a small study on female(女性)college students. In the test they share chocolate with someone they thought was another participant(参与者). But in fact, it was a scientist. In each test, they got two pieces of chocolate. They ate one piece at the same time with the “participant” and the other piece alone. The participants thought the chocolate was tastier and more enjoyable when they shared it with someone. Even though both pieces of chocolate were from the same box.
Scientists then did another experiment, this time with bitter, unpleasant chocolate. Again, the participants thought the chocolate was bitterer than the piece they ate alone.
“When people think of shared experience, what usually comes to mind is being with friends or Family.” said scientist Erica Boothby. “We often don’t know how much people around us influence (影响)our decisions.” according to Erica.
However, it does show that sharing things with a friend may just make your good way a little brighter. Because the study only looked at female college students, it doesn’t mean the whole (全 部的)picture.
1.According to the new study,___________________-.
A. the best film is the one you watch with your friends
B. sharing secrets with your friends can make you happier
C. the most delicious meal is the one you have with your family
D. your experiences are stronger if your share them with others
2.Which of the following statements is WRONG according to the test?
A. The chocolate has two different tastes.

A. Erica Boothby really likes eating chocolate
B. making more friends can make you luckier

Have you ever eaten a whole packet of biscuits when you were planning to only have one? Or have you stayed up much later than you planned, or even all night, having “just one more” try in a game? Both of these are examples of mindlessness. When we live this way, we are not fully awake and not fully living our lives.
When we are mindful, we are different. We are conscious of our thoughts, our actions and what is happening around us. We might notice a beautiful sunset or really listen carefully to what a friend is saying, rather than planning what we’re going to say next. We are also clear about our own feelings and thoughts. So we are consciously deciding what to pay attention to, we are not worrying about the past or planning for the future and we are not trying to control or stop our thoughts or feelings—we’re just noticing them.
For most people, life is getting busier and more stressful(有压力的). Technology means
that we always have something to do and there isn’t much opportunity to just “be”. People are often doing two or three things at the same time: texting while watching TV, or even looking at phones while walking.
Research shows that mindfulness reduces stress. It can help you to focus, to have a better memory and to think more clearly. It can also help you to manage pain better and to improve sleep, and it can even help you to lose weight because you won’t eat that whole packet of biscuits without thinking!
A very simple technique that you can try right now is to close your eyes for a few minutes and count how many sounds you can hear. This will help you to focus on what is happening right now. Another technique is to focus on a piece of food. Instead of eating it without thinking, notice how it feels and how it tastes.
Both of these techniques help you to slow down and focus on the present moment, as Jon Kabat Zinn says, mindfulness is: “Paying attention, on purpose, in the present moment, and without judging. ”
1.Why does the writer ask two questions in the first paragraph?
A. To predict the influence of stress. B. To describe the modern way of life.
C. To introduce the topic of mindfulness. D. To show the importance of healthy habits.
2.The underlined words “be conscious of” in Paragraph 2 probably mean “ ”.
A. be ready for B. know something well
C. be careful with D. take something seriously
3.Which of the following is an example of mindfulness?
A. Listening to the birds singing with patience. B. Having potato chips as much as you’d like to. C. Watching a movie with a large box of popcorn.
D. Taking pictures of flowers when walking in a park.

Have you ever seen a horse with toes? Millions of years ago, horses had many toes. They had four toes on each front foot. They had three toes on each back foot. The horses were no bigger than the cats. These small horses lived in the forest. The toes helped the horses run on the soft, wet ground.
At first, it was very hot in the forest. But the weather changed. It became very cold. Many trees could not live in cold weather. The trees died and fell. Open fields took the place of forests. The sun made the ground dry and hard.
Horses began to change, too. They began to get bigger. This took a long time. On the dry, hard land, horses needed only their middle toes for running. Their middle toes became hard. After a long time, horses had only one hard toe on each foot. Now we call this hard toe a hoof(蹄子).
