It will emit an electromagnetic spectrum that is good enough for the process of photosynthesis(光合作用). They are most commonly used in winter.This is because winter is the coldest time of year with a large number of clouds covering up the natural sunlight. It is vital for plants to receive enough sunlight to grow. An LED grow light is a very efficient tool for gardeners during the winter season because it allows them to continue growing plants that are generally made for the summer and spring.The grow lights imitate the same light given from the natural sunlight. They can also be adjusted to emit only enough light to stimulate the growth of a particular type of plant. The LED grow lights are able to mimic the different temperatures of the weather. This is done using various colors that are made by the grow lights. It is also made possible by the different levels of intensity(强度) that can be adjusted on the LED grow lights. The lights can be adjusted based of the stage of cultivation of the plants. This can be concerning the growth stage, flowering phase, or the fruiting phase.Home and garden stores will have all the equipment needed for growing a healthy garden, and as more people start using LED technology, they will carry even more options. LED grow lights are increasingly being used outside the industrial sector, though. People who love to grow their own plants outside and in personal greenhouses use the lights as a permanent element of growing their plants. Some people only use the grow lights when they are needed, such as in the winter. As LED lights become more popular, people are finding ways to use them creatively and maximize their output. Whether through the use of mirrors or greenhouses, it is clear that plants benefit from their use. It looks like LED grow lights are here to stay.根据短文内容，选择最佳答案。1. The grow lights was invented _.

Rowling planted the idea of an invisibility coat in her blockbuster(大片) Harry Potter book series, scientists have been falling all over themselves to create a material that can not only camouflage(伪装) people, but also camouflage buildings. Now a Canadian company claims to have won that race with a magical textile that it properly calls “Quantum Stealth”.British Columbia based Hyperstealth Technology Corporation claims that the material makes its wearer completely invisible, even to people with night glasses. Also, just like the young wizards coat, it is lightweight and does not need cameras, batteries, lights or mirrors to operate. But best of all, it is cheap to manufacture!So how does it really work? Well that is a top secret. Besides stating that they have successfully managed to bend light waves, so that they go around the material instead of through it, the company is not giving out any details. What it does detail is all the good uses Quantum Stealth could be put to - Ranging from protecting US and Canadian soldiers forced to step into enemy region, to allowing special armed forces to carry out surprise attack without any fear of being seen. And if that is not enough they even imagine creating aircrafts and submarines that can go completely undetected.To prove that Quantum Stealth really exists, the company has released photos and even a video showing its magical properties. For those that are still skeptical, they have only one thing to say - Both the US and Canadian Military officials have witnessed it live and are so impressed that they are now working with Hyperstealth Technology to create the next generation survival blanket that could make the soldier invisible all at once! If this is indeed true, we have only one question - When will this magical fabric be available to the rest of us?根据短文内容，选择最佳答案。1.

Passage 1题材体裁难度系数字数题数阅读时间正确率科学技术说明文32720 20 分钟/resources/143725-why-food-cooks-faster-pressure-cooker.aspx First time in my life, I was totally astonished when I saw the pressure cooker used for cooking around in 1987. It was totally 1 to see all those cooking activities whistling of the pressure cooker. Denis Bapin 2 the pressure cooker in 1679. Before going to the mechanism(原理) of cooker, let us see the physical 3 hidden behind this cooker. The boiling point and the atmospheric pressure are 4 . The boiling point of water on the earth at the sea level is 100 degree Celsius. The water gets boiling when the vapour pressure(汽压) 5 the atmospheric pressure. In the higher altitude, the atmospheric pressure is 6 so the water starts boiling in between 70 degree to 80 degrees. At this temperature, cooking is not possible because we 7 lots of heat for cooking our food items. 8 low atmospheric pressure, cooking is not so popular in those places of higher altitudes. 9 this concept of inter-relation between the boiling temperature and the atmospheric pressure, Denis papin dedicated(奉献) his invention to the people of the world community in the 10 of pressure cooker. He noted by increasing the 11 inside the cooker, the temperature can also be increased to maximum 12 and that gave the idea of designing pressure cooker.When we add the cooking material with sufficient amount of 13 , within a short time the water gets heated to 14 the boiling point of 100 degree Celsius. 15 still the water inside the pressure remain unboiled. So under the extreme temperature the food particle gets cooked 16 . It cooks faster by saving time for the busy people. This is a 17 for the working people. The accumulating steam inside the pressure cooker 18 the vapour pressure, which finally pushes the whistle to 19 the person who is cooking to indicate the food particles get cooked. Whistling sound makes you 20 of the food cooked. 阅读短文，选择能填入空白处的最佳答案。1. A. frighteningB. amazingC. interestingD. disgusting2. A. presentedB. inventedC. broughtD. bought 3.
