    "Sesame Street" has been called "the longest street in the world". That is because the television program

by that name can now be seen in many parts of the world. That program became one of American exports

soon after it went on the air in New York in 1969. 

    In the United States more than six million children watch the program regularly. The viewers include more

than half the country's pre-school children, from every kind of economic, racial (种族的), and geographical

group.

    Although some educators object (反对) to some parts of the program, parents praise (赞扬) it highly.

Many teachers also consider it a great help, though some teachers find that problems come out when first

graders who have learnt from "Sesame Street" are in the same class with children who have not watched the

program.

    Tests have shown that children from all racial, geographical, and economic backgrounds have benefited

(受益) from watching it. Those who watch it five times a week learn more than occasional (偶尔的) viewers.

In the US the program is shown at different hours during the week in order to increase the number of children

who can watch it regularly.

    The programs all use songs, stories, jokes and pictures to give children a basic understanding of numbers,

letters and human relationships. But there are some differences. For example, the Spanish program, produced

in Mexico City, devotes more time to teaching whole words than to teaching separate (单独的) letters.

    Why has "Sesame Street" been so much more successful than other children's shows? Many reasons have

been suggested. People mention the educational theories (理论) of its creators, the support by the government

and private businesses, and the skillful use of various TV tricks. Perhaps an equally important reason is that

mothers watch it along with their children. This is partly because famous adult stars often appear on it. But

the best reason for the success of the program may be that it makes every child watching it feel able to learn.

The child finds himself learning, and he wants to learn more.

1. "Sesame Street" is actually ______.  [ ]

阅读下面的散文，完成下面的题。

　　去年的一个春日下午，我约朋友们到家里喝茶。我们坐在阳台上，就着茶，透过落地玻璃窗，赏着不远处的一片农田，田里的油菜花肆意汪洋，在春日的阳光下无羁奔腾。大片的油菜花，仿佛带上了王冠，穿行在春天的检阅台，视察眼前的仪仗队，浓艳中有一股王者之气，凛然、亲和又不可侵犯。

　　有个朋友说，用不了多久，这油菜花，这块地终将消失。

　　一年后，还是在一个春天的下午，我约了朋友到家喝茶。还是在同样的阳台，透过窗子，我们再也看不到去年那样汪洋的油菜花了。去年的那片土地四周已经被围墙围起来，麦田中央插着十几架打桩机。几辆挖掘机像蛮牛一样，霸气十足，冒着黑烟挖掘着泥土。不远处已经有数十幢高楼拔地而起，主体已经结束。被围墙围起来的农田里还没有打桩的地方，有油菜花孤零零地开着，分布在打桩机的周围。

　　朋友说，油菜地果然消失了。太阳还是那个太阳，土地却不再是往日的土地。不多的油菜花没有了往日的王者之气，很容易让敏感的我想到一个词：残喘。这个词，总是用来形容那些弱势群体，但我用这个词来形容一片土地，形容一片土地上无辜的花，实在有点儿残忍。我很清楚，用不了一个月时间，油菜花还没有完全结出饱满的菜籽就会夭折。取而代之的将是钢筋、水泥、电线杆、机器、噪音、商铺。想到这里，我有点儿伤感，有点儿沉重。

　　商业的触角伸到哪里，哪里的美就会被扼杀。机器的轮子转到哪里，哪里的安静就会被戕害。开发的红头文件发到哪里，哪里的土地就会被刺伤。房子越建越高，自然的美就越来越矮；现代文明的铁塔越立越多，天籁和安详就越来越少。

　　春天里，我和朋友们喝着新茶，谈论春天里美好的事物和不美好的事物。内心波动的那份静谧因为一串串沉重的打桩声而支离破碎。油菜花谢了，我们的心也跟着慢慢空了。新生的事物取代往日的美好，我不知道今后我们留给这个世界的是墓碑还是挽歌。

　　春天去了还会再来，而被机器的铁蹄践踏过的土地还能萌生诗意和美感吗？时代仿佛就是一个飞速运转的轮子，我们追求快节奏、快感、快乐，这轮子呼啸而过，挟裹着我们骨子里所向往的自由、美好、宁静，我们已经慢不下来了！诗意被剥落，美感被戕害，宁静被驱逐，工业的快速兴旺如同得势的帝王，统领现代人的步履冲锋陷阵，一些东西正在消失。商业的遍地繁荣，如同流水线上那刻板的程序和标签，将一些朴素的事物和本真的品质打包、归类、作价。

　　土地被侵犯，美被物化，自然的教母再也不可能捧出足金的花朵。生命里一些良好的秩序被机器遗弃，血液里良好的基因被工业的能量、商业的气息、物质的利手摒弃。一转身，那块土地不见了；一转眼，那束菜花不见了；一转弯，那份心境不见了。我不知道这是时代的悲哀还是内心的悲凉。

　　作为这个时代机器上的一枚不起眼的螺丝，我尽可能地让自己的心，慢一点再慢一点，让自己的脚步，慢一点再慢一点，我只想用自己蚂蚁一样柔弱的双唇，亲吻一朵花天真的容颜；我只想用蜗牛一样的步履背着自己精神的粮仓，悄悄地将春天里正在消失的美折叠成诗行，决然藏进背上的躯壳，深入泥土腹部，用一生的时间来温习春天，温习生命里最柔软的时光。
