Clothes are important and necessary to us, but do you know how to choose suitable clothes in a correct way? Here are some ideas for you．

When you go shopping and want to buy some clothes，you should think about which kind of clothes you really need and decide how much money you can spend on them．Then look at the labels that are inside the new clothes. They tell you how to take care of the clothes．The label for a shirt may tell you to wash it in warm water. A sweater label may tell you to wash it in cold water. The label on a coat may say “dry clean only” and cleaning in water may ruin this coat. If you do as the directions say on the label, you can keep your clothes looking their best．

Many clothes today must be dry-cleaned. Dry cleaning is expensive. When buying new clothes, you had better check if they need to be dry-cleaned. You can save money if you buy clothes that can be washed or that are well-made. Well-made clothes last longer. They look good even after they have been washed many times.

Clothes that cost more money don’t always mean they are better made. They may not fit you, either. On the other hand, less expensive clothes may sometimes look better and fit you well.

Ⅰ.据报道，美国耶鲁大学的生物学家正在从事将病毒引诱到人体“陷阱细胞”中，以防止病毒繁殖的试验研究。例如，HIV通过T细胞表面的CD4识别T细胞（如图甲），如果给AIDS患者注射大量用CD4分子修饰过的红细胞（如图乙），则该红细胞也会被HIV识别、入侵。但HIV在红细胞中无法完成复制增殖，最后随红细胞的死亡而被清除，该方法目前已经在小鼠体内获得阶段性成果。

某生物兴趣小组设计一个模拟实验来研究人体的免疫系统的某种防御作用。实验材料：可封口的无菌塑料透明袋4个、表面消毒的新鲜苹果4个、腐烂的苹果肉少许。实验器具：无菌棉棒、牙签、外用消毒酒精等。

小组同学将实验分为四组分别作如下表处理。在实验进行的一星期中，每天定时观察约15min，记录观察结果。请回答：

小组同学模拟的是人体非特异性免疫中（）的屏障作用。实验中，腐烂果肉模拟的是（）。
