“I didn’t think about that，”I said.
“I know，”Grandpa said.“But a good man should never take __32__ of someone else’s hard work.”
Suddenly I felt a bit __33__.The image of the starving squirrel wouldn’t __34__ my mind.There was only one thing I could do.I carried the basket back to the tree and poured all the nuts into the hole.

Ⅲ.阅读理解
A tent can be one of the more costly items on your camping equipment shopping list.It is definitely something that you need to consider carefully.
By seeing a tent for real you will be able to get a better impression of its size and construction in the traditional shop.However，the downside is that，unless you are experienced，you may miss out some of the details that the manufacturer’s promotional material makes clear.Cheap tents often look similar to the quality models they are mimicking(模仿)，but you can be sure that they use inferior(次的) materials and probably have lower design standards.
Shop staff are often campers themselves.That means they usually can give lots of advice.If a shop assistant agrees with your own conclusions，that will be great；if they try to change your decision with a clear and reasonable argument，then that will be worth considering；if they just try to bamboozle(欺骗)，or even bully，you then walk away.
The Internet is a wonderful tool，and so long as you know how to make the most of search engines and put in a little effort，you really have the perfect answer waiting to be found.That answer will be different for every camper as each of us has different needs.Don’t be surprised to see your favourite criticized somewhere，but if you see too much criticism，then you had better start thinking again.No problem.You won’t have spent anything yet，so think of it positively as a large expense saved.
Probably the best approach，if you have the time，is to research tents online and make a short list.Then try to inspect those tents at nearby shops.Then you can make a final decision on where to buy your chosen model based purely on total cost.
