今年的“五一”假期,我是在新加坡和马来西亚度过的。新加坡和马来西亚的景色虽然都非常的好看,但令我最难忘的还是在新加坡的一个晚上。在这个晚上,我在圣陶沙公园,观看了一场精彩的音乐喷泉表演。

大家是不是都知道新加坡的鱼尾狮?鱼尾狮是新加坡的标志,一共有三座鱼尾狮雕塑;这几座鱼尾狮都是由狮头和鱼身组成的。它们有一个在新加坡的市中心;有一个在新加坡最高的山上;还有一个在新加坡的圣陶沙。其中最好看、最令我难忘的还是圣陶沙的那座鱼尾狮。

5月5日的晚上,我们早早地就来到了圣陶沙公园,观赏这里的鱼尾狮,也在这里等候着音乐喷泉演出的开始。等了一段时间,演出终于开始了。首先出场的是一位“小丑”,他手拿指挥棒,很像一位指挥家。哎,还真没说错,他就是这场音乐喷泉演出的指挥家。他的手一摇,喷泉就跟着他的手型喷水;要是他两只手都在动,所有的喷泉都一起喷水,彩色的灯光照在喷泉上,五颜六色的水柱,真是好看极了!

在这场音乐喷泉演出里,音乐时高时低,时快时慢;有时是流行歌曲的节奏,有时是经典的古老歌曲的声调,真是好听极了!喷泉也随着这动听的音乐翩翩起舞了。

“哇”,此时,全场传来一阵惊讶声,原来是水幕电影开始了。我从小一直到现在从来没有看过水幕电影,这还是我第一次看呢!水幕电影就是把水喷成像一块屏幕,然后再把动画投影上去,这就叫水幕电影了。这场水幕电影里的主要人物是一只又淘气,又可爱的小猴子,叫“keykey”,它欢蹦乱跳的邀请了“小丑指挥家”去跟它一起玩,没想到的是,水幕电影里还真出现了“小丑指挥家”的样子,真是太神奇了!我知道是投影的,但是水为什么真的被溅起了呢?哎,搞不懂……

时间就这样不知不觉的过去了,这场精彩的演出在美妙、动听的音乐声中结束了。虽然这场音乐喷泉的表演时间很短,只有25分钟,但却给我留下了深刻的印象。

这个晚上让我非常难忘,它对我来说是非常的具有纪念意义,因为这是我第一次出国旅游,也是在这次新马旅游中过得最开心的一个晚上,还是我第一次在这美好的夜晚观看我出生以来从来没看过的水幕电影!

Directions: For this part, you are allowed 30 minutes to write a short essay entitled Goal Setting Is Important by commenting on John Ruskins famous remark, Living without an aim is like sailing without a compass. You should write at least 120 words but no more than 180 words.

【范文】Goal Setting Is Important

Living without an aim is like sailing without a compass. This philosophical wisdom by John Ruskin, one of the greatest British writers, tells us that goal setting is extremely important in life.

Why is goal setting so important? The main importance of goal setting is that it provides us with direction and purpose. When we have goals, we know what we want to achieve so that we can focus our mindson a single worthwhile target and avoid getting distracted easily. Personal goal setting also provides us with motivation to achieve what we want to achieve.

Goal setting is of especial significance for todays students. A study reveals that when students set goals, they learn the importance of taking responsibility, of minimizing excuses and of helping others. Goal setting is a lifelong skill that first helps students succeed in school and then later in life.

人体有着90%以上的,因此水是必不可少的。也不是什么水都能喝,许多水都是对人体有害的。

生水及未处理过的水,这种水常含有各种各样的细菌、病毒和寄生虫。喝了生水,很容易引起疾病和寄生虫感染。况且如今工厂、生活废水、农药残余等污染严重,喝生水引起疾病更是高频率。

死水,也就是长时间不动的水,常饮这种水,对未成年人来说,会使细胞新陈代谢明显减慢,影响生长发育;中老年人则会加速衰老;老化水及死水中的有毒物质,也会随着水贮存时间增加而增加。

沸腾时间长和反复煮沸的水也不能喝。这种水因煮过久,水中不发挥性(重金属)含量高。久饮这种水,会干扰人的消化功能,造成昏迷,甚至死亡。

蒸馏水是实验室用的水。这是普通水蒸发后的水蒸气在空气中出现“液化”而形成的一种干净、无任何杂质的水。常饮这种水,会导致机体严重缺乏各物质,疾病便闻风而来。

不开的水也不能喝,人们饮用的自来水,虽然经消毒灭菌处理过。但是,终有生命顽强,漏网之鱼的细菌未被消灭,而低温无法杀死这些“佼佼者”。而这些细菌,有害物质大都有致癌作用。那么,怎样净化水?

其实很简单,化学实验中的过滤法既简单方便又实用。面对浑浊的水,要将其净化,可以先沉淀(也可直接过滤),然后只取上部分水,用一根小棒引流,在三层滤纸上过滤。这样,不溶物质便留在了滤纸上,为了使水更加洁净,可以在其它干净滤纸进行多次过滤,最后,再加热使水沸腾杀菌。这样,便得到了一杯较干净的水。

在生活中,人们也“依样画葫芦”,在水质差的地方,往往制造了各种大同大异的“净水器。”在水龙头口包裹几层纱布便是最原始的方法。

我相信将来的新兴产业肯定有净水处理器,未来的水也会越来越安全。

A dream is to a man what wings are to a bird. With a dream in the deep hearts core, a man is spontaneously driven to hitch his wagon to a star.

A dream is an inexhaustible source of energy that keeps our enthusiasm burning, and kindles our desire to enhance our spiritual cultivation, refine our character, and upgrade our quality of life. A life without a dream is like a bird with broken wings, confined to a cage and oblivious of what lies beyond the range of its vision. On the contrary, a man with a dream is like a warrior armed with ambition, foresight and gallantry, daring to step into an unknown domain to make a journey of adventure. It is dream that adds fullness, variety, and spice to our life and makes it worth living.

I have a dream. It is a dream that is deeply rooted in human nature. I dream that one day people of all origins can live in harmony and peace without being discriminated against or persecuted. The bounty of the earth can be shared by every single human being. Mutual respect will guarantee the existence and continuation of the diversity of customs and cultures. Love, sympathy, and cooperation will alleviate the sufferings and disasters inflicted upon our fellow men. Respect for basic human rights will put an end to social injustices and evils. When my dream comes true, all men will be truly equal, happy, and free.
