It's generally believed that nothing in the world is precious than life．You can't help feel sorry for the woman after you look at the picture．In this picture，the driver's mother is crying sadly for her son'death caused by his drunk driving．In recent years，drunk driving has become a hot topic．It is said that a number of people who died each year due to drunk driving in the world is much larger than that of people who die in a modern war．Unfortunately，our government has taken plenty of measure against drunk driving．People believe that may help prevent from this dangerous behavior．Most important，in my opinion，drivers themselves should realize the importance of give up drunk driving．
分析 本文主要介绍每年因酒驾死亡的人数比现代战争死亡的人数还多．幸运的是，我们政府采取了许多反对酒驾的措施．同时，司机本人也应意识到放弃酒驾的重要性．
解答 It's generally believed that nothing in the world is∧precious than life．You can't help feel sorry for the woman after you look at the picture．In this picture，the driver's mother is crying sadly forher son'death caused by his drunk driving．In recent years，drunk driving has become a hot topic．It is said that a number of people who died each year due to drunk driving in the world is much larger than that of people who die in a modern war．Unfortunately，our government has taken plenty of measure against drunk driving．People believe that may help prevent from this dangerous behavior．Most important，in my opinion，drivers themselves should realize the importance of give up drunk driving．
详解：
1．is后加more 考查形容词比较级．根据句中than要用比较级，precious是多音节形容词，变成比较级时要在其前加more．
2．feel改为feeling 考查动名词．can't help意为"禁不住"，后接动词时要用动名词形式．
3．for改为over 考查固定搭配．cry over意为"为…哭泣"，是固定搭配．
4．a改为the 考查冠词．a number of意为"许多"，the number of意为"…的数量"，此处应是"每年因酒驾而死亡的人数"．
5．died改为die 考查动词时态．根据句中时间状语each year要用一般现在时态．
6．Unfortuately改为Fortunately 考查副词．根据句意：幸运的是，我们政府采取了许多反对酒驾的措施．应是"幸运地"．
7．measure改为measures 考查名词复数．measure意为"措施"，是可数名词，plenty of后接可数名词要用复数形式．
8．去掉from 考查动词用法．prevent是及物动词，后直接接宾语，不加介词．
9．important改为importantly 考查副词．修饰句子要用副词，形容词important的副词是importantly．
10．give改为giving 考查动名词．of是介词，后接动词时，要用动名词形式．
点评 高考短文改错题的形式有说明文，短文故事，书信等，具有很强的实用性．短文的内容和语言都符合高中学生的实际，从表面上看类似一篇学生习作．首先，通读全文，了解短文大意，把握全篇的时态、人称及行文逻辑，在通读全文时把一些容易的错误先改好，再进行逐句改错．其次，要进行逐个句子的改错．这是要对文中的词法、句法和语篇着重分析和特别注意．最后把改好的短文再阅读一遍，检查答案是否正确，感觉是否还有不妥之处，最终形成定稿．

8．Why Blue LED Lights Won the Nobel
The 2014Nobel Prize in physics went to three scientists who gave lighting a big change by inventing blue LED lights．A big change in lighting efficiency is under way around the world．
Save and green
LEDs use less energy than other forms of lighting．A typical LED bulb（灯泡） can produce around 83lumens per watt-a measure of how much brightness you can get from a unit of electrical power-much more efficient than other lighting facilities．
LEDs produce light by passing electric current through a semiconductor，while traditional bulbs pass current through a wire．The wasted heat energy is chiefly why traditional bulbs are so much less efficient．
LEDs also last about 30times longer than traditional bulbs，and many LED bulb products promise up to 25，000hours of use-more than 17years if you used one for about four hours a day．
Lighting the world
The lighting transformation is not only in homes．LEDs are also being used for street lights，public holiday and decorative displays，commercial buildings，and other large energy users．
Car lighting is another application where LEDs are making progress．LEDs used to be used only for daytime running lights，but now many new cars have LED headlights for night-time use．
LEDs also hold promise for bringing light to the more than 1.5billion people around the world without access to electricity，the Royal Swedish Academy of Sciences noted．Indeed，several proposed solutions to energy poverty include the distribution of LED lights，particularly solar-powered ones．
Digital displays
Without blue LEDs，the world wouldn't have back-lit smart phones，TV and computer LCD screens，blu-ray（蓝光） players，many forms of lighting，and countless other products．
In the electronics industry，LEDs provide back lighting for LCD screens in many smart phones，laptops，and televisions．The LEDs are more energy efficient and allow for very thin displays．
Blu-ray players use blue LED lasers（激光） to read data off a digital optical disc．When these systems switched from using an infrared（红外线） laser to a blue LED laser，it became possible to store five to 10times as much data．
LEDs are now being explored for their potential uses to transmit（传送） data from the Internet across open space，similar to WiFi．Such a system could transmit a lot more data than WiFi alone．This high bandwidth is possible because LEDs can turn on and off millions of times per second．
The rise of LED lighting came at a time when people were just starting to be concerned about global warming．Because of LEDs'energy efficiency，using them for the world's lighting would affect environmental protection in a positive way．

14．Why You Should Embrace Your Depression
Depression affects millions of people worldwide，and while some of them suffer from mild and short-lived depression，others suffer from a deep state of depression all the time．While being depressed is certainly a negative thing that can seriously affect your life，it also has its upsides．Here are some reasons why you should embrace your depression-accepting it and realizing its advantages is a big step toward overcoming it!
It's widely known that some of the world's greatest writers and painters created their excellent works when they were depressed or deeply hurt．It is almost an unwritten rule of the universe：when you experience a high level of sadness and depression，you tend to create deeply moving things．This is precisely what makes depression such a huge contradictory （自相矛盾的） thing these days，since for some of them depression is often associated with a lack of focus，determination or motivation．
Another common view surrounding depression is that it prevents you from thinking clearly．For some people，however，it actually helps them concentrate and see things in a totally different light．This aspect of depression applies especially if the depression was caused by an extremely upsetting life event，such as the loss of somebody dear to you．
Depression can teach you to find reasons for living，which may sound contradictory，since depression is often associated with a lack of desire to live，but in some cases where a person is so depressed that they only see the world in"black and white，"the depression can help them find reasons for living and going on．Life will try to bring you down more than once，but it is important to stand up more times than you fall down．Depression can help make you look back and see where you may have done wrong，and what you can correct to make things better．
When people are depressed，they tend to believe there is nothing good left in the world．However，it often happens that our friends and family show their true support when we are down and we need them．Depression can be a good test to see who is with you and who will flee at the first sign of weakness．Being depressed means that you will need the moral and emotional support of those close to you-and it will undoubtedly make you cherish your health，your friends and your family．Unfortunately，many of us tend to take these things for granted until it is too late．
Depression is certainly not something one would wish for，but it doesn't mean that you cannot make something positive out of it．Those suffering from depression should try to keep an open mind and to analyze all the pros and cons of situations objectively，and they might be amazed to see that there are actually several upsides they have never taken into consideration．
