解答 36-40：CFBGE
36．C 考查上下文理解判断能力．根据下文The monkeys pick up the phone when it rings，carry shopping bags and do housework可知，猴子接电话，搬运购物袋及做家务，这些都要使用手，上文应是：它们能学会如何帮助那些不能使用手和腿的人．故选C．

38．B 考查上下文理解判断能力．根据上文It knows how to find beehives but it can't open them and get the grubs．People like to eat honey，but they aren't very good at finding beehives可知，导蜜鸟知道如何找到蜂窝但打不开，而人喜欢吃蜂蜜但找不到蜂窝，下文应是：他们相互帮助．故选B．
39．G 考查上下文理解判断能力．根据下文When the dolphins find a large group of fish，they make a noise to tell the fishermen可知，当海豚找到一大群鱼时，它们弄出吃亏告诉渔民，上文应与海豚有关，即：海豚通过作用声音很容易找到鱼．故选G．

点评 七选五题型看似简单，实际上有时完全作对并不容易，需要方法和分析能力及足够的耐力，有必要进行专门练习．首先，快速浏览一遍七个备选答案，先确定哪个选项适合放在文章的什么位置．其次，快速浏览文章，确定文章体裁，抓住文章结构，分析篇章结构，找出各段的主题句或主旨大意．其三，注意各选项中出现的句子衔接手段，寻找句中衔接标志词，七选五备选答案中有两个多余的选项，会对文章中两个空的选择构成干扰，这时要特别细致地比对相似选项．最后，用代入法，检查答案是否合理，将所有选择答案放回空白处，通读全文，检查文章内容是否语义连贯合理、紧扣主题，语篇结构是否通顺连贯、具有一致性、合乎逻辑，写作思路是否清晰明了，格式以及用语是否恰当贴切，从而判断选择的答案是否正确．
