Most students have biology classes in the classrooms or the labs in China．But several days ago，I had a biology class outside in my American schoo1．
My biology teacher，Mr.Kwak，divided us into three groups and asked us to play a game about natural selection(选择)and how birds find food．
He gave the first group one spoon per person，the second group forks and my group"knives．I thought we were going hunting，so knives might work better．Surprisingly，he told us to pick up the beans on the grass with our tools．
When the game started all of us ran to the grass area．We squatted(蹲)down and looked for beans．It was hard to pick up something that small，especially from the grass .
When I almost fired a bean，it dropped back to the ground．When I finally picked up several beans．one of my friends ran into me．I couldn’t keep my balance and fell over．All my beans dropped to the ground!Just at that moment，Mr．Kwak called us back．I had to leave the game and of course I got a bad result．I couldn’t help thinking that if I were a bird living on Galapagos Island，I would be dead soon．
The fun game made me realize that natural selection is redly competitive(竞争的)．Everyone is trying his or her best to—survive．
1.What did the writer’s group use to pick up the beans?

4.What’s the meaning of the underlined word“survive’’in the last paragraph?
A．Find food． B．Remain alive．
C．Be lovely． D．Keep balanced．
5.What was the aim of Mr．Kwak’s class?
A．To play an interesting game．

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(较暗淡的)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．
