3.Marco Polo travelled across Europe and Asia with his father,(71)who wanted to do trade with the Chinese.Eventually,they arrived in Beijing.At that time,China (72)was ruled (rule) by the Yuan Dynasty Emperor,Kublai Khan.Marco was amazed (73)to find(find) how beautiful and powerful China was and how(74)impressive (impress) Beijing and the Emperor's Palace were.It also surprised and even (75)confused(confuse) him to see paper money (76)used (use) in the markets and black stones serve as fuel..In 1291,after 17years of service(77)to the Emperor,Marco returned to Italy as a very wealthy man.Unfortunately,a local war broke out and he was caught and put into prison.(78)However,Marco was lucky enough to meet (79)another prisoner who enjoyed listening to his (80)stories (story) about China and wrote a book called The Description of the World.
分析 本文主要介绍The Description of the World这本书是如何被完成写作的.
解答 71.who 考查定语从句.分析句子结构可知这是一个定语从句,先行词father指人,在从句中作主语,用关系代词who.
72.was ruled 考查动词时态和语态.China与rule之间是动宾关系,要用被动语态,且时间是过去时间,要用一般过去时的被动语态.
73.to find 考查动词不定式.此处动词不定式作原因状语.
74.impressive 考查形容词.be后要用形容词作表语.
75.confused 考查动词时态.and是并列连词,它前后连接两个相同的语法成分,surprise和confuse都应用一般过去时态.
76.used 考查过去分词.paper money与use之间是动宾关系,用过去分词短语usee in the markets用宾语补足语.
77.to 考查介词.service to意为"对…服务",是固定搭配.
78.However 考查副词.however表示转折,尤其用于谈及一个既成事实时,表示转折,其意为"可是""仍然"等.可放在句首、句中或句末,通常用逗号与句子其他成分隔开.
79.another 考查限定词.此外指"另一个囚犯",用another.
80.stories 考查名词."他的故事"不止一个,要用复数形式.

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.
Why Blue LED Lights Won the Nobel
The reason why blue LED lights won the 2014 Nobel Prize in physics is that they are to (81)resultin big changes in lighting. | |

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.
