问题 问答题

某市拟于距市区3km处新建一座总装机500MW抽水蓄能电站。工程枢纽由下水库、输水系统、电站厂房、上水库和辅助设施组成。工程下水库利用现有水库,输水系统、电站厂房和上水库需要新建,上水库库容218万m3。工程总占地面积236hm2,永久占地205hm2,临时占地31hm2。水库淹没林地4.3hm2,草地85hm2。下水库目前有水产养殖项目,水质不能达到功能要求。电站上游2.5km为一国家重点风景名胜区。施工区分为上水库区、厂房区和管理设备区三部分,各区通过公路相连接。

给出本项目主要环境保护措施。

答案

参考答案:主要环境影响:(1)施工期:水土流失、施工噪声、施工扬尘、人群健康影响、工程占地及水库淹没的影响。
(2)运营期:对项目区水文、水质的影响,对生物多样性影响,对社会、经济和土地利用的影响。
措施:(1)施工期:水土流失防治措施,施工噪声可以从选用低噪声的施工机械或工艺,加强设备的维护和保养等方面防治施工噪声,施工扬尘可以通过优化施工工艺等方面来降低施工扬尘,生态等方面则可以从生态恢复措施等方面进行考虑。
(2)运营期:为避免库区水质遭到进一步破坏,建议在库区周边严格限制新建污染型企业及污染项目:为减小项目运行后对生态环境及生物多样性的影响,水库运行后,在不发电时,应保持一定的生态下泄流量,以消减对下游河道生态环境及生物多样性的影响。

完形填空

Ideally speaking, criticism(批评) is the act of making comments on someone or something with the purpose of improving products or service. However in daily life, you will meet some people criticizing with the negative purposes,

What should you do when you are being criticized? Actually, you should take it positively. It is possible that the person who criticizes you has rightly drawn your attention to something which needs improving. If this is the case, be thankful to the person because he is helping you to know where to improve.

However, there is also a chance that the criticism is being done just to make you sad. So if necessary, ask one of your friends or workmates what he thinks of this criticism. If the criticism is really meant to hurt you, pay no attention to it and don’t allow it to disturb your peace of mind.

When you are criticizing someone or something, always remember that negative criticism causes negative energy, so try to criticize in a positive manner. Do not become the “full stop” for someone’s creativity

Whenever you are about to criticize, ask yourself whether your purpose is to help the person or if you are just going to spread negativity which will damage someone’s creative skills.

If you really want to criticize someone, do it in an encouraging way. Try to give your comments in this way so that he can put your suggestions into corrective(改正的) actions. What’s more, you should remember the fact that complaining is taking criticism to the next level which is even more damaging and dangerous. So try to remain inside the limits of criticism instead of complaining.
