Question

Butterflies are common all over the world，but butterflies in hotter countries are usually bigger and more brightly colored than those in coo1er countries，and there are more different kinds．
Usually the male(雄性的)butterflies are more brightly colored than the females．The females have bigger and heavier bodies since they carry the eggs．The bright colors of the males help to attract the females，and the duller(較暗淡的)colors of the females make them less likely(可能的)to be caught by enemies before they have laid their eggs．
Some butterflies have bright pattern colors on the upper surface of their wings that show when flying ,but when they rest on a tree or leaves , they close their wings．On the undersides of their wings there are green and brown marks which look like the tree or leaves．They are then difficult to be seen．The best example of this is the Dead Leaf Butterfly．When its wings are c1osed，it looks exactly like a dead leaf．There are even marks that look like the holes in a dead leaf．When the butterfly is run after by a bird，it closes its wings and seems to have disappeared completely．
Many butterflies have round marks on their wings that look like eyes．The round marks have a useful function(功能)．When the butterflies are resting，their wings are closed，and these marks can’t be seen.  When a bird sees one，and begins to attack it，the butterfly will open its Wings. The bird thinks that it sees two eyes staring at it，frightened，and flies away．

試題分析：本文介紹了世界上有許多不同種類的蝴蝶，雌性的蝴碟的體形比雄性蝴蝶的大。當(dāng)蝴蝶被鳥追趕的時候，它就關(guān)閉翅膀，好像翅膀早就消失了一樣，蝴蝶身上的圓斑，會嚇跑鳥的。
小題1:細節(jié)理解題。根據(jù)The females have bigger and heavier bodies since they carry the eggs．雌性的蝴碟因為身上帶著卵，所以身體體形大，故選A。
小題2:細節(jié)理解題。根據(jù)the duller(較暗淡的)colors of the females make them less likely(可能的)to be caught by enemies 暗淡的顏色能夠使雌蝴蝶防止被抓住，故選D。
小題3:詞義猜測題。根據(jù)Some butterflies have bright pattern colors on the upper surface of their wings that show when flying可知這里前文提到的pattern colors ，故選B。
小題4:細節(jié)理解題。根據(jù)When the butterfly is run after by a bird，it closes its wings and seems to have disappeared completely．當(dāng)蝴蝶被鳥追趕的時候，它就關(guān)閉翅膀，好像翅膀早就消失了一樣，故選C。
小題5:細節(jié)理解題。根據(jù)The bird thinks that it sees two eyes staring at it，frightened，and flies away．
可知鳥看見蝴蝶身上的圓斑，就認為是兩只眼睛在盯著看它，就嚇得飛走了，可推知這里敘述的是蝴蝶原斑的作用，故選D。
