In recent years, tourism has developed rapidly in China. Many people believe that tourism produce positive effects on economic growth and we should try our best to promote tourism. But what these people fail to see is that tourism may bring about a disastrous impact on our environment. As for me, I'm firmly convinced that too much tourists bring harm to the environment.
The bad impact of tourism on the environment has mainly expressed itself in various ways. One way is the proceof exploiting a new scenic spot. In order to attract tourists, a lot of artificial facilities have been built, which have certain unfavorable effects on the environment. This proceusually breaks the ecological balance of the area. In some mountainous places, trees are being cut down to build hotels for others to see and explore the beauty of the mountains. Then land slides and mud-rock flows come up. Another way the development of tourism has damaged the environment occurs when tourists go to scenic spots. Some tourists don't have the awareneto protect the environment, and ignorantly throw their garbage here and there. Some people even kill the local wildlife to eat, which badly damages the balance of the natural environment.
It is wrong to sacrifice the environment for the growth of tourism. We must keep in mind that too much tourists bring harm to the environment. We need to find a balance between satisfying the needs of tourists and reducing to a minimum the pollution they cause.

Will Tourism Bring Harm to the Environment? Tourism has developed by leaps and bounds in the past decades in the whole world. Therefore, the issue of whether the tourism will bring harm to the environment is becoming a matter of concern. As for me, I hold that the tourism does more harm than good to the world. In the first place, the more places we travel to , the more pressure will be added to the environment. Take Dunhuang as an example, the greatest scourge these days comes from the tourists who swarm here by the busload , bring destructive amounts of carbon dioxide and moisture into the caves along with their eagernefor a glimpse of ages past . Secondly, It has become fashionable for travelers to drive a private car to the place they want to . In this case ,a large number of cars are mushroomed in the road and it cause twice as much as air pollution .At this speed ,we may live in a world which is full of dirty air instead of fresh air. In sum , although tourism is playing an indispensable we`d better try to limit role in the society , I still believe that its speed according to the harm that brings to the environment.
The world we live in is becoming more and more intolerable because of environmental destruction. Bird flu and Sars are two typical examples that environmental destruction may threaten our life. Besides, forest destruction , water and air pollution result in decrease of planting land and unpleasant weather.
Serious as the problem seems, we can come up with some measures to deal with it. First of all, the authorities should adopt the policy of "sustainable development", and laws concerning environmental protection should be put into effect and enforced strictly just as our government has been doing.
What' s more, every citizen should realize the seriousneof the problem and make concerted efforts to protect our environment. In addition, planting trees helps improve and beautify the environment.

艾在端午
①《诗经·采葛》曰：彼采葛兮，一日不见，如三月兮!彼采萧兮，一日不见，如三秋兮!彼采艾兮，一日不见，如三岁兮!其中的萧与艾都是现在的艾。艾是一年生或多年生草本，常成群生于路旁、墙脚或草坪中，叶面绿色，叶背呈灰绿色，生有绒毛。
②艾，是端午节的主角，端午节的别名艾节，就是以艾命名的。端午，又称端阳，其时正是寒暑气交互转换之时，蚊虫苍蝇滋生，细菌病毒繁殖，人易生病。古时，人们缺乏科学观念，误以为一并皆由鬼邪作祟所致，所以古人称五月为恶月或百毒月，端午为恶日。自古至今，艾在端午中受到人们的挚爱，人们用它招百福、辟邪祟、祛毒害。
③古代的一些经史书籍常有端午节悬艾人、戴艾虎、饮艾酒、食艾糕、熏艾烟、洗艾浴等民间习俗的记载。没奶年端午节之际，家家都洒扫庭除，以艾条插于门楣，悬于堂中以防蚊虫，避邪却鬼。
④据专家考证，艾用于治病已有2000多年的历史。我国现在的第一部方书，战国时期的《五十二病方》中就记载有艾的疗效与用法，以后在历代本草中均有记载。在我国盛产优质艾的湖北蕲州，至今还流传着家有三年艾，郎中不用来的谚语，孟子也说过：七年之病，求三年之艾，可见艾的药用价值。
⑤艾在端午，客观上也起到了卫生保健的作用。有人把端午节作为古代卫生节，也是不无道理的。

奇招击退红潮
丹丘生
① 在湖泊和海洋里，当藻类一生二、二生四，四省八这样漫无节制地繁殖起来的.时候，就形成了红潮。红潮来时，因藻类生长吸收了太多的氧气，致使当地的水域严重缺氧，大量水生植物窒息而死，此外，红潮还会在水中释放出神经毒素，使与之接触的人感染上呼吸道和神经系统疾病，甚至患上癌症。
②一直以来，人们都对红潮束手无策，他们所能做的，只是听天由命，按事物发展盛极必衰的规律，耐心等待着红潮自己消失，但现在，科学家终于找到了一种消除红潮的办法用超声波消除藻类。
③藻类之所以能漂浮在水面，而不会沉到水底，是因为它们身体里含有一种浮力细胞，里面含有氮气气泡，它们就像藻类与生俱来的救生圈，靠着这些气泡的浮力，就使整棵植株漂浮在水面上。
④而人们就抓住了藻类的这一特点，用特定频率的超声波引起浮力细胞里的气泡共振，当共振达到一定强度，气泡就会把细胞胀破，使得藻类失去浮力的支撑而下沉。一旦失去了水面的阳光，藻类在水下很快就会死亡。
⑤最近，一个英国研究小组利用三种不同频率的超声波对项圈藻进行了测试。他们发现，尽管三种频率的超声波在一定程度上都能起作用，但效果最好的是频率接近1兆赫的超声波，这个频率刚好是项圈藻中浮力细胞的共振频率。
⑥不同种类的水藻，因为大小不等，它们的共振也是不一样的。所以，这项技术可以有针对性地去除某一种类的水藻。此外，这种除藻办法不会伤及其他的水生植物，因为其他的水生植物的细胞对于超声波来说太致密了，不容易引起共振。
⑦由于高频率超声波在水中传播时，会很快被吸收，譬如1兆赫的超声波作用范围半径只有20米，所以这项技术在小范围的湖泊和池塘里，、比在动辄方圆千米的大海里更为实用。
7.请用简洁的语言概括红潮的危害。(3分
8.全文的说明顺序是什么?请简洁概括作者是怎样按这种顺序进行说明的。(4分
9.第③自然段运用了哪种说明方法?它有什么作用?(3分
10.下列说法或推断符合原文意思的一项是( (3分
A.凡是红潮繁殖的水域，水生植物都无法生存。
B.击退红潮的奇招就是用特定频率的超声波来消除藻类。
C.藻类浮力细胞的共振频率是1兆赫。
D.频率为1兆赫的超声波对漂浮在方圆数千米的大海里的红潮不会起作用。
