奇妙的植物世界

       世界上有许许多多奇妙的植物。

       植物能吃虫。夏天,在沼泽地带常常可以看到一种淡红色的小草,这就是会捕捉飞虫的毛毡(zhān)苔(

tái)。毛毡苔的叶子上有200多根小绒(róng)毛,这些小绒毛能分泌出一种黏(nián)性很强的液体,这种黏液还含有一种很甜的味道和香气,小虫子一闻到这种气味,就急急忙忙地飞来,一旦落到它的叶子上,就会被牢牢地粘(zhān)住。经过1~2小时,小虫就被叶子消化吸收掉了。   

       植物还会听音乐呢。一位印度的科学家常喜欢在花园里拉小提琴,放交响乐。日子久了,他竟然发现那园中的花木,长得格外旺盛。于是,他开始正式对水稻进行试验。他每天在一块稻田里播放25分钟交响乐。一月后,发现这块田里的水稻比同样一块没听过音乐的水稻要长得更加茂盛,平均株高超过30厘米。

       此外,还有预报地震的山芋藤(téng),能净化水的水葫芦,会“咬人”的漆树……

阅读理解。

     A father's job is unique. If parents had job descriptions, mine would read: organize bills, play dates,

laundry, meals, carpool, snacks and outings. The only thing on my husband's description would be the

word "fun" written in big red letters along the top.

    Our parenting styles complement each other. His style is a nonstop adventure where no one has to

worry about washing their hands, or eating vegetables. I'm too busy worrying to be fun. Besides, every

time I try, I am constantly outdone by my husband.

    I bought my children bubble gumflavored toothpaste, and I taught them how to brush their teeth.  

They thought it was neat until my husband taught them how to rinse(濑口)by spitting out water between

their two front teeth like a fountain.

    I tried singing fun songs as I washed behind my children's ears during bath time. They enthusiastically

sang and clapped until their father came in and taught them how to catapult (弹射) the soap into the sink

with the washcloth.

    I took the children for a nature walk to corral (把……赶入……) a slow ladybug(瓢虫)into my son's

insect cage. I was "cool" until their father came home, spent two minutes in the backyard, and captured

a beetle the size of a Chihuahua (吉娃娃,一种产于墨西哥的狗).

     I try to tell myself I am a good parent even if my husband does things I can't do. I can make sure my

children are safe. But I can't wire the VCR so my children can't watch their favourite video.

     I can carry my children in my arms when they are tired and kiss them good night. But I can't flip

them upside down so they can walk on the ceiling or prop them on my shoulders so they can see the

moths flying inside the light fixture.

     I can take them to doctor appointments, but I'll never go into the wilderness to fish. I'll even sit in the

first row of every Little League game, but I'll never teach my children how to hit a home run or slide into

first base.

     I can do a lot of things for my children, but no matter how hard I try, I can never be their father.
