When I was growing up, I had an old neighbor named Doctor Gibbs. He didn’t look like any doctor I’d ever known. He never yelled at us for playing in his yard, but was always very kind.
When Doctor Gibbs wasn’t saving lives, he was planting trees. His house sat on ten acres, and his life’s goal was to make it a forest. He had some interesting theories about planting trees. He hardly watered his new trees, which flew in the face of conventional wisdom. Once I asked why and he told me that watering plants spoiled them because it made them grow weaker. He said you had to make things tough for the trees so that only the strongest could survive. He talked about how watering trees made them develop shallow roots and how, if they were not watered, trees would grow deep roots in search of water. So, instead of watering his trees every morning, he’d beat them with a rolled-up newspaper. I asked him why he did that, and he said it was to get the tree’s attention.
Doctor Gibbs died a couple of years after I left home. Every now and then, I walked by his house and looked at the trees that I’d watched him plant some twenty five years ago. They were all tall, big and robust since they have deep roots now.
I planted a couple of trees myself a few years ago. Two years of attending these trees meant they grew up weak. Whenever a cold wind blew, their branches trembled. Adversity(逆境) seemed to benefit Doctor Gibb’s trees in ways comfort and ease never could.
Every night before I go to bed, I check on my two sons. I often pray that their lives will be easy. But lately I’ve been thinking that it’s time to change my prayer. I know my children are going to meet with hardship. There’s always a cold wind blowing somewhere. What we need to do is to pray for deep roots, so when the rains fall and the winds blow, we won’t be torn apart.
【1】With the trees planted, Doctor Gibbs __________
A. kept watering them every morning
B. paid little attention to them
C. talked to them to get their attention
D. beat them to make them grow deep roots
【2】The underlined word “robust” in para.3 probably means _________?
A. strange B. deep C. strong D. old
【3】 Which of the following will be the author’s prayer on the days ahead?
A. Have an easy life, without too much to worry about.
B. Meet people like Dr. Gibbs in the future.
C. Have good luck, encountering less hardship in their life.
D. Be able to stand the rain and wind in their lives.
【4】Which of the following can be the best title of the passage?
A. Growing roots
B. Doctor Gibbs and his trees
C. Prayers for my sons
D. Watering trees
【答案】
【1】B
【2】C
【3】D
【4】A
【解析】
【1】B 细节理解题。根据文章第二段第四句 “He hardly watered his new trees,” 可知他对小树很少关注。故选B。
【2】C词义猜测题。根据该句“They were all tall, big and robust since they have deep roots now. ”可知小树因为扎根很深变得高大而强壮。tall, big, deep roots都是提示。由此可知C项正确。
【3】D细节理解题。根据最后一段最后一句“What we need to do is to pray for deep roots, so when the rains fall and the winds blow, we won’t be torn apart.”我们需要做的是祈祷他们能像小树一样根深蒂固,这样他们在面对风雨时我们就不会分离了。可知D项说法正确。
【4】A主旨大意题。通读全文可知,文章讲的是通过种树的体会联想到到养育孩子—要让孩子经历挫折,这样才能风雨无阻。正如小树经历风雨才能根深蒂固一样。故选A。

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.
