It seems that a family just isn't complete (完整的) without a pet. But if pets aren't suitable to a family's lifestyle or environment, they can quickly lead to problems such as stress or arguments (争执). To save yourself and your family such problems, treat this decision seriously. When choosing a pet, people must consider the family's health. Many people are allergic (过敏的) to cats and dogs. Perhaps a dog or cat with short hair will be fine. And a dog might not be the best choice for a child who is naughty (顽皮的) because the dog might bite him or her. Some people can also have problems with certain pets. It's a good idea to spend a little time with the pet around each member of the family before making your decision. Consider the quality of life of the pet, too. If a pet is used to having space to run around, it can quickly develop psychological (心理的) problems when it is kept in a small flat all day. If pets are allowed to run about in areas with lots of traffic, they can meet an early end. Cats shouldn't be brought into homes that already have large dogs because they won't be able to get along well with each other.

    The decision as to what kind of pet to choose is very important. If you find the right one to suit (适合) everyone in the family and their lifestyle, then it's time to choose one. Remember that your decision is important because it can have effects that last for many years.

    Those days when you go on vacation, you spend most of your money just getting there. Travel is expensive, but don't stay home only because you are short of money! Here is some advice:

    Travel during off season if possible. Flights and hotels are much cheaper when tourism is low.

    Choose a hotel that's a little farther from popular attractions. If you're staying several days, check out prices on vacation homes-- they can end up being cheaper than a hotel.

    Take public traffic, such as buses or subway, instead of taking a taxi.

    Plan your meals, and cat like locals. Don't waste money at expensive hotel restaurants or fast- food chains. Depending on where you stay, it may be cheaper to make food on your own.

    Check online for special discount (折扣)—if you're a student, the old or the parents traveling with children, you could get discounts! A little research could save you a lot of money.

    Whether you're backpacking alone or going on a family vacation, your trip doesn't have to cost a lot of money. The key is to plan ahead and write down what you spend. Then put the money you save toward your next trip!

Now students' English handwriting（书法）gets worse and worse. That makes their teachers feel worried. Is your English handwriting beautiful? If not, here are four steps that really work!

u  Using paper with lines (线条)

Using paper with lines can keep you writing straight when you write English words or sentences. Those lines on the paper can help you to write words in the right size.

u  Slow down

If your writing is hard to read, try slowing down a little. For some kids, going slower makes the handwriting clear. If you write too fast, it's hard for you to stop where you should, and even worse, you may make more mistakes.

u  Hold your pencil right

When you hold your pencil the correct way, writing is much easier. Try to be relaxed and don't hold the pencil so hard while writing, and then it makes your handwriting nice and clean. If you do so, people will think you are a student with a good habit.

u  Draw more pictures

Drawing can improve your handwriting. You need to use the skills to control(控制) your pencil better when you are drawing pictures. If you have no time for drawing at school, you can practice it at home.

Some have good handwriting and some don't. Anyway, handwriting is very important. You need to take time to improve it.
