a essay for IELTS who can correct it for me,please?
Topic: Some people think university educations should prepare students for employment while others think it should help students require theoretical knowledge. Discuss views and give your own opinion.
My essay:
With the population boom, the competition in job market has become increasingly stiff. Therefore, someone believes that the main aim of higher education is to improve students' employability. However, others argue that students should focus on gaining theoretical knowledge at university. Both of sides will be discussed.
Clearly, the purpose of most students attending to university is to improve their competitiveness in future job market. Hence, if university can offer them easily access to employment skills, it is not only beneficial to students' career prospects after graduation, but also may enhance the university's attraction to most people. Furthermore, because of strong support by government, university has a wide view on the whole society which makes it clearly knows what is the most needs in job market. Last, country economy will increase stronger with more good employable graduates, as students are the future of a country.
On the other hand, we have to say the merits of theoretical knowledge are also manifested. To start with, theoretical knowledge is the solid foundation of high technologies. Employment skills boost the quality of students' material life, whereas the theoretical knowledge will increase their spiritual life. In addition to this, students who have a good command of theoretical knowledge will perfect well on academic study and research in future and this will definitely advance the improvement of our country's economy, technology etc..
In conclusion, university should provide different students who have different requirements with a variety of courses. Only do this, can students fulfill their potential.

谁能帮我把这篇文章翻译成英语。Could you help me translate the document into English?
西藏自治区位于青藏高原的主体,地理位置特殊,不仅是南亚、东南亚的江河源和生态源,而且对于调节中国乃至东半球气候至关重要。
西藏的经济收入主要以农牧为主,因此,相应地农业用水也至关重要。
1、“一江两河”---农田主要分布在此,农田灌溉对西藏地区很重要
Here,一江两河是指西藏自治区的雅鲁藏布江、拉萨河和年楚河的中部流域地区。
西藏区内现有农田390 余万亩, 主要集中在“一江两河”中段地区。
随着西藏地区人口的增长和生活水平的提高,人们对粮食和农副产品的需求逐步提高,相应地,耕地灌溉面积也会逐渐扩大、农业灌溉用水的增加。根据预测的人均需求和人口数,到2030 年,西藏按粮食和能源自给计算,需增加农田16.41 万hm2 ,经济果林2.92 万hm2 ,新增人工草地3.7 万hm2 ,由此需增加农业用水19 亿t 。
虽然,水资源总量、人均水资源拥有量等位居全国第一,但是西藏地区水资源时空分布极不
均匀和开发程度较低,至今尚有1/ 3 的耕地不能得到有效灌溉,且西藏农田90 %以上为灌溉用水。因此农田灌溉对于保证西藏的粮食安全和边疆起到重要作用。
(1)灌溉用水来源
西藏的灌溉用水主要来自于降水、冰雪融化水和地下水三种。这三种水季节分配不均,上半年径流量仅占全年径流量的20-30%,下半年约占全年的70-80%。其中7-9月份占全年的55-65%,所以,在耕地比较集中的河谷地区如拉萨河、年楚河等流域的耕地,在春季和夏初时期,灌溉农田用水严重不足。
(2)干旱缺水---制约农业发展
目前, 西藏农业生产的主要问题是干旱。西藏的干旱主要是由于降水少, 降水年内分配不均以及农田耗水量大的矛盾所引起的, 在一江两河地区, 年平均降水量只有300~ 450mm, 成为我国较干旱地区.就我区农业用水而言, 灌溉高峰期在4一6月, 此时降水量很少, 径流亦很小。干旱缺水加剧了灌溉用水紧张的局面灌溉水利用率普遍偏低, 另外, 由于城市生活和工矿企业用水急剧增加, 大量无偿挤占农业灌溉用水。
(3)水资源浪费---传统的漫灌、水资源利用系数低
在灌水方式上, 大多采用传统的地面灌溉, 漫灌现象严重, 西藏地区只有几个示范节水灌溉点,对于小畦灌、定额灌、波涌灌、隔沟灌、膜上灌、膜下灌等,在内地已有一定的推广,在西藏还少见。从总体上来看,我国农业水资源利用效率不高。全国平均灌区田间水利用系数0.6~0.7 ,西藏地区的农业水资源利用率则更低, 0.4~0.6 , 而西藏的主要农区———“一江两河”地区灌区田间水利用系数只有0.4~0.6 ,即约有一半的水被浪费。
3、Improved irrigation of water productivity
针对西藏地区特殊的特点,近年来主要采取
(1)工程节水---渠道防渗、管道输水
西藏地区多河滩漫地,渠道衬砌多采用干砌石、浆砌石,这种渠道使许多水分渗漏。近几年,通过利用西藏渠道抗冻防渗的混凝土配合比,对于渠道安全运行很有效果[7 ] 。另外,管道输水,可大大减少水资源在运输过程中的损失。西藏土壤多为沙土和沙壤土,渗漏性大,利用管道能够有效减少渗漏,提高利用率,同时由于西藏早晚温差大,利用管道输水深埋地下也能避免渠道冻融现象。
(2)地面灌溉节水---从传统粗放灌溉到现代化技术
目前,西藏的地面灌溉仍采用传统的沟畦灌水方法,由于畦块大,灌水沟畦过长,灌水量很难控制。可采用地面灌溉、沟灌技术、畦灌技术和膜上灌技术。西藏地区以种植大田作物为主,小麦、青稞占了90 % ,农耕粗放,比较适合改进的畦灌技术,在平整土地的基础上,利用土埂将田块分成小块,畦长不超过75 m。同时还应发展喷、微灌,对目前研制出的控制灌溉、波涌灌、地面浸润灌溉等新方法、新技术进行研究,找出适合西藏地区新的灌溉技术。
(3)农艺节水---改良土壤结构的保水性能
①大力推广土壤改良,改土蓄水。西藏的耕地土壤主要是沙土,土壤贫瘠,跑水、跑肥。通过改良土壤,减少跑水、跑肥,蓄积降水,保墒,促苗。②利用覆盖保水。覆盖能有效地减少土壤水分蒸发,延长土壤抗旱能力。
筑堤坝
(4) 管理措施节水
重视田间水管理和农民的参与。推广节水农业,必须重视农民的参与; 加强灌区用水的信息管理,实现计划用水,合理调配水量,促进灌溉管理向自动化发展;健立水权制度,通过水价调节用水。
