任务型阅读。

     认真阅读下列短文，并根据所读内容在文章后表格中的空格里填入一个最恰当的单词。注意。每个空格只填1个单词。

     You probably have lists of remember and steps to follow in order to have the best pet-friendly trip.

There are, however, a few things that are best left at home. Here are a few things to forget when you're

traveling with pets. Forgetting them will make your trip run more smoothly and more effectively.

     Time

     Traveling with pets will take longer and will have unexpected turns. In reality, forgetting about time

means leaving impatience behind. Don't be in a rush. Your pets will require more extra stops than you

will, and they'll often surprise you with unpredictable delays. Plan on leaving early and arriving later and

you'll be right on time.

     Anger

     Getting angry at the delay will only make matters worse. Your feelings can add unnecessary stresses

to you and your pets' travel experience. If you feel yourself becoming out of control, stop and take a

deep breath. Your pets have little control over their emotions, bowel movements, or motion sickness

when traveling. Remember to be kind and understanding at all times, especially when under pressure.

     Work Attitude

     This may seem like a no-brainer, but when you are traveling, leave your work attitude behind.

Traveling is not a task to be accomplished; it can be an enjoyable and memorable experience for both

you and your pets as long as you have the right attitude.

     Control

     Part of the joy of traveling with pets is dealing with the unexpected. You can't control everything and

trying to do so will only end in frustration and anger. Knowing that things will happen beyond your

control will bring great relief to you and your pets. Messes happen; accidents happen. Once you accept

that, traveling with your pets will be far easier to manage.

     Selfishness

     Traveling with pets often requires an extreme amount of selflessness. Your pets rely on you to take

care of their needs, and sometimes you will need to put their needs before your own. Leave your selfish

ambitions behind when traveling with your pets. They need your attention and care more than anything

else because of the stresses and strains of traveling.

     Traveling with pets can and will be a joy if you remember to leave these five items behind. It can be

difficult at times to handle, but the traveling will go well if you can manage to do so.
