【推荐1】Living together with other students may be a wonderful experience for you. If you can deal with it well, you and your roommates will probably enjoy a happy life and even build a lifelong friendship.     1    

Choose your roommates carefully if you are given permission. Combining the living spaces of several students into one location can be an exciting and beneficial experience for the outgoing students.     2    

Divide the bills equally. Some students are far less responsible than their roommates.     3     Resentment is quick to build when everyone has to pay the bill for a fellow student who can't seem to pay his share of the money.

Carry your part of the load. Everyone has to clean the bathroom and the kitchen sometimes. Don't avoid your part of responsibility. Student accommodation can get messy and it involves everyone to keep tidy and healthy.

    4     Put your roommates' interests above your own. Life will be far more enjoyable when everyone is concerned about the feelings, property, and studies of each other.

Be open and honest. Hostility between roommates may cause problems that can't be fixed. Everyone brings different standards and expectations to group living.     5     Disagreements can be managed when you are willing to both be open and listen to others.

A．They tend to let their part of the finance slide.

B．Here are a few tips for student accommodation.

C．It is quite easy to get along with outgoing students.

D．Think about someone else before you think about yourself.

E．It's in everyone's best interest to put them into the open.

F．If you are on the shy side, or prefer a quiet group, pick quieter roommates.

G．Telling a lie or saying rude words to your roommates may hurt their feelings.

【推荐2】Many people have a fear of public speaking. They try to avoid public speaking because they worry that they will lose their words, bore the audience (听众) or somehow make a fool of themselves.     1     You may give a talk in a class or a meeting. Or you’ll give a toast (敬酒) at a wedding. Maybe you’ll have to give an acceptance speech for some honor you’ve received. Follow these steps to satisfy your audience and get rid of (摆脱) your fear of speaking in public.

Know your topic. Try to speak about a subject you know well.     2     Public speaking is harder when you look like an outsider.

Relax.     3     Your audience don’t expect you to be. They want you to succeed just as much as you can do. Let out nervousness by giving up all your anxious thoughts. If you’re thinking you’ll forget everything, remind yourself that you are prepared.

    4     You are not Jack Canfield or Tony Robbins. So, don’t try to copy what you think a public speaker should be. Share your true personality with your audience. Don’t pretend to be somebody that you’re not.

Pay attention to a few main points.     5     Your audience will not remember every little detail you tell them. They’ll be satisfied if they leave with something they can use, and that is what public speaking is all about.

A．Be yourself.

B．Know who you will speak to.

C．Don’t push yourself to be perfect.

D．Everyone has to speak publicly at some point in their life.

E．Research into the topic to make sure that you fully understand the details of it.

F．What’s the most important is that you have to be prepared for what you are going to say.

G．You’d better base your speech on 2 or 3 main points and pay attention to these main points.

【推荐1】Below is a selection from a popular science book.

If blood is red, why are veins (静脉) blue?

Actually, veins are not blue at all. They are more of a clear, yellowish color. Although blood looks red when it’s outside the body, when it’s sitting in a vein near the surface of the skin, it’s more of a dark reddish purple color. At the right depth, these blood-filled veins reflect less red light than the surrounding skin, making them look blue by comparison.

Which works harder, your heart or your brain?

That kind of depends on whether you’re busy thinking or busy exercising. Your heart works up to three times harder during exercise, and shifts enough blood over a lifetime to fill a supertanker (超级油轮). But, in the long run, your brain probably tips it, because even when you’re sitting still your brain is using twice as much energy as your heart, and it takes four to five times as much blood to feed it.

Why do teeth fall out, and why don’t they grow back in grown-ups?

Baby (or “milk”) teeth do not last long; they fall out to make bigger room for bigger, stronger adult teeth later on. Adult teeth fall out when they become damaged, decayed (腐烂) and infected by bacteria. Once this second set of teeth has grown in, you’re done. When they’re gone, they are gone. This is because nature figures you’re set for life, and what controls regrowth of your teeth switches off.

Do old people shrink (收缩) as they age?

Yes and no. Many people do get shorter as they age. But, when they do, it isn’t because they’re shrinking all over. They simply lose height as their spine (脊柱) becomes shorter and more curved due to disuse and the effect of gravity (重力). Many (but not all) men and women do lose height as they get older. Men lose an average of 3-4 cm in height as they age, while women may lose 5 cm or more. If you live to be 200 years old, would you keep shrinking till you were, like 60 cm tall, like a little boy again? No, because old people don’t really shrink! It is not that they are growing backwards—their legs, arms and backbones getting shorter. When they do get shorter, it’s because the spine has shortened a little. Or, more often, become more bent and curved.

Why does spinning make you dizzy?

Because your brain gets confused between what you’re seeing and what you’re feeling. The brain senses that you’re spinning using special gravity-and-motion-sensing organs in your inner ear, which work together with your eyes to keep your vision balance stable. But when you suddenly stop spinning the system goes out of control, and your brain thinks you’re moving while you’re not.

Where do feelings and emotions come from?

Mostly from an ancient part of the brain called the limbic system (边缘系统). All mammals have this brain area—from mice to dogs, cats, and humans. So all mammals feel basic emotions like fear, pain and pleasure. But since human feelings also involve other, newer bits of the brain, we feel more complex emotions than any other animal on this planet.

People who are near-sighted can only see things that are very close to their eyes. Everything else seems ­­blurry. Many people who do a lot of work, such as writing, reading and sewing become near-sighted. People who are far-sighted suffer from just the opposite problem. They can see things that are far away, but they have difficulty in reading a book unless they hold it at arm’s length. If they want to do much reading, they must get glasses, too.
Other people do not see clearly because their eyes are not exactly the right shape. They have what is called astigmatism (散光). This, too, can be corrected by glasses. Some people’s eyes become cloudy because of cataracts (白内障). Long ago these people often became blind. Now, however, it is possible to operate on the cataracts and remove them.
Having two good eyes is important for judging distances. Each eye sees things from a slightly different angle. To prove this to yourself, look at an object out of one eye; then look at the same object out of your other eye. You will find the object’s relation to the background and other things around it has changed. The difference between these two different eye views helps us to judge how far away an object is. People who have only one eye cannot judge distances as people with two eyes.
