课外阅读。

　　春天到了，两颗种子躺在肥沃的土地里，开始了下面的对话。

　　第一颗种子说：“我要努力生长！我要向下扎根，还要出人头地，让茎叶随风摇摆，歌颂春天的到来……我要（感受　感叹）春阳照耀脸庞的温暖，还有晨露滴落花瓣的喜悦。”

　　于是，它努力向上生长。

　　第二颗种子说：“我没那么勇敢。我若向下扎根，也许会碰到硬石；我若用力往上钻，可能会伤到我脆弱的茎；我若长出幼芽，难保不会被蜗牛吃掉；我若开花结果，只怕小孩儿看了会将我连根拔起。我还是等情况安全些再作打算吧。”

　　于是，它继续（瑟缩　收缩）在土里。

　　几天后，一只母鸡到庭院里东啄西啄，这颗种子就这样进了母鸡的肚子。

                                                     Stingrays (黄貂鱼)

    Stingrays are pancake-shaped fish, and you'd never guess it: they're close cousins of sharks.The

smallest kinds are about the size of a dinner plate. But some 4-metre stingrays live in the waters near

Australia. About 170 different kinds of stingrays live in the oceans around the world. And some live

in freshwater too. In South America, a few kinds swim in the Amazon and other rivers that flow into

the Atlantic. One ocean kind, the Atlantic stingray, also

lives in the St. Johns River in Florida.                        

      A stingray has a mouth and nostrils(鼻孔) on the bottom of its body. These nostrils are for smelling,

not for breathing. When water flows into a stingray's nostrils, the fish may pick up the smells of creatures

it wants to eat. It can also find prey (牺牲者) by sensing the tiny amount of electricity that animals give

off. Slowly, slowly the fish hunts by moving along the ocean or river bottom. When it senses a worm,

clam, shrimp, or other creature, it flaps (拍打) its fins until the prey is uncovered. Then the fish lies down

over the prey, sucks it in, and crunches it with its small teeth. A stingray's flat shape helps it hide. It stirs

up a cloud of sand by flapping its big, flat fins. When the sand settles down over the fish, everything is

covered but its eyes, breathing holes, and sometimes its tail. Its tail gave the "sting" to a stingray's name.

When a stingray is attacked by an enemy, it whips its tail around. Then a sharp stinger releases a powerful poison into the enemy. When stingrays are on the ocean bottom, it's easy for a diver to step on one by

mistake. Then the fish usually stings the person in the ankle. The poison is very painful, and the wound

may hurt for a day or two. Worse yet, pieces of the stinger can break off and infect the ankle. But

stingrays don't chase after prey or people to sting them. In fact, divers can swim among friendly stingrays

without getting hurt.
