I, together with my two friends, were eating dinner at a Chinese restaurant, located in the center of New York. I noticed the young woman eating with two kids. We stop by and I asked the kids if he believed in Santa. The elder boy, whom was about seven years old, pointed his younger sister and said, “She does, but I don’t. ”I told them Santa was real and as we were paying for our dinner, I paid for theirs, either. I didn’t know that whether the woman was alone, but I grow up with my mother supporting us four kids alone. I still feel good thinking I may have helped on some small ways.
【答案】
【1】were—was
【2】the—a
【3】stop—stopped
【4】he—they
【5】whom—who
【6】pointed后加at
【7】either—too
【8】去掉that
【9】grow—grew
【10】on—in
【解析】
试题分析:这是作者叙述了自己小时候虽然家境不好,但仍然看到困苦的人就立即去帮助的故事。
【1】were—was 考查主谓一致。该句的主语是I,应用was。
【2】the—a 考查冠词。此处的young man是第一次出现,应用不定冠词a。
【3】stop—stopped 考查时态。根据上下文此处应用一般过去时,故改为stopped。
【4】he—they 考查代词。根据该句前面的kids,应用they代替。故改为they。
【5】whom—who 考查定语从句。根据从句中缺少主语,故whom改为who。
【6】pointed后加at 考查介词。根据point是不及物动词,故其后加at。
【7】either—too 考查副词。根据该句是肯定句,表示“也”应用too。
【8】去掉that 考查宾语从句。根据该句中只用一个引导词whether,故去掉that。
【9】grow—grew 考查时态。根据上下文应用一般过去时,故改为grew。
【10】on—in 考查介词。根据词组in some small ways在一些小方面。故改为in。

请认真阅读下面短文,并根据所读内容在文章后表格中的空格里填入最适当的单词。注意:每空一个单词。
Why Blue LED Lights Won the Nobel
The 2014 Nobel 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 83 lumens 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 30 times longer than traditional bulbs, and many LED bulb products promise up to 25,000 hours of use — more than 17 years 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 1.5 billion 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 10 times 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.
