It seems that there’s a good reason why dogs are always seen as man’s best friend. Scientists have found that dogs are the only animals that can read emotion(情感)in faces much like humans. The finding suggests that like an understanding friend, dogs can see if we are happy, sad, pleased or angry.

When humans look at a new face, their eyes usually look across the left, falling on the right hand side of the person’s face first. A possible reason for this is that the right side of the human face is better at expressing emotions.

Scientists have now shown that pet dogs also have “l(fā)eft gaze bias(左視偏好)”, but only when looking at human faces. No other animal has been known to do like this before. Dr. Kun Guo with his team showed 17 dogs the pictures of human, dog and monkey faces as well as something else. The dogs’ eyes and heads show a strong left gaze bias when the animals see human faces. But this did not happen when they were shown other pictures, including those of dogs.

Guo suggests that over thousands of years living with humans, dogs may have developed the left gaze bias as a way to guess our emotions.

“Recent studies show that the right side of our faces can express emotions better than the left. If true, then it makes sense for dogs and humans to see the right hand side of a face first.”

1.Why are dogs seen as man’s best friend according to the passage?

A. Because dogs are the closest animals to humans.

B. Because dogs can read the emotions in humans’ faces easily.

C. Because dogs can understand us better when we feel sad.

2.The dogs’ left gaze bias helps them _______.

A. get along well with humans

B. express emotions quickly

C. have more understanding friends

D. remember more new faces

3.The passage mainly wants to tell us that _______.

A. dogs have been man’s best friends for thousands of years

C. the “l(fā)eft gaze bias” works on all animals

D. dogs can read emotions the same as humans

We are all called upon to make a speech at some point in life, but most of us don’t do a very good job. This article gives some suggestions on how to give a successful speech.

So, you have to give a speech and you’re frightened. You get nervous, you forget what you want to say, you stumble(結(jié)巴)over words, you talk too long and your listeners feel tired of your speech. Later you think, “Thank goodness, it’s over. I’m just no good at public speaking. I hope I never have to do that again.”

Cheer up! It doesn’t have to be that bad. You can do the following things to take the pain out of speech making. Ask yourself the purpose of your speech. What is the occasion(場(chǎng)合)? Why are you speaking? Then, collect as many facts as you can on your subject. Spend plenty of time doing your research. Then spend plenty of time putting your material in good order so that your speech is clear and easy to follow. Use as many examples as possible and use pictures, charts and graphs if they help you make your points clearer. Never forget your listeners. Don’t talk over their heads and don’t talk down to them. Respect your listeners. They will enjoy your thoughtfulness.

Just remember： Be prepared. Know your subject, your listeners and the occasion. Be brief. Say what you have to say and then stop. And be yourself. Let your personality come through so that you make person-to-person contact with your listeners.

If you follow the simple things, you’ll see that you don’t have to be afraid of public speaking. In fact, you may find the experience so enjoyable that you volunteer to make more speeches! You’re not confident yet. Give it a try and see what happens.

Have you had a headache during a test? Have you ever been so worried about something that you have a headache or even can’t sleep at night? If so, then you know what stress is. Stress is what you feel when you are worried about something. This worry in your mind can make your body feel bad. You may feel angry, sad, scared(恐懼的), or afraid—all of which can give you a stomach ache or a headache.

However, there are different kinds of stress. Some kinds of stress are good and others are bad. Good stress might happen when you’re called to answer questions in class or when you have to give a speech. This kind of stress can help you to get things better done. For example, you may do a better job in your test if the stress pushes you to prepare better before the test.

On the other hand, bad stress can happen if the stress lasts too long. You may not feel well if your parents are fighting, if a family member is sick, if you’re having problems at school, or if anything else makes you unhappy every day. That kind of stress isn’t going to help you. And it can actually make you sick.

The best way to face the stress is to have a balanced life. Make sure you keep yourself in mind: Sleep, exercise, leisure(休閑), and food. If you get enough sleep and eat healthily, and if you exercise and leave time for fun, you’ll probably feel less stressed.
