Read the article and select the best answer. Article: Almost all of us have been there: A sense of uneasiness strikes us when we see the battery running low on the smartphone. While today's smartphones enable us to surf the Internet, take pictures and play music, their limited, sometimes annoyingly short battery life has started to make people full of memories of early models. "My favorite phone of all time was a silver Nokia 6310i from the early 2000s. It may be primitive by today's standards, but it could run for 17 days on a single charge," wrote Daily Mail columnist David Derbyshire. But scientists spend no time thinking about the past. They have built an aluminium battery which could be a cheap, fast-charging alternative to current designs. You can squeeze, and practically bend it in half without breaking the packet. It is more environmentally friendly than alkaline batteries, and more safe than lithium batteries - it won't catch fire "even if you drill through it", as Hongjie Dai of Stanford University told The Telegraph. The battery is the work of a team led by Dai. And the best part is that it has a recharge time of around one minute. However, at present, the only problem is that it produces just half the voltage of a typical lithium battery. But Dai explained they were setting about changing the voltage and energy density ". "Our battery has everything else you'd dream that a battery should have. I see this as a new battery in its early days," he told The Telegraph. Question: Which of the following can best summarize the passage? Options: A: A new battery in its early days. B: A new trend in the smartphone market. C: The annoyance short battery life causes D: The invention of a new smartphone battery.

Read the article and select the best answer. Article: If you are a sleep deprived teacher, you may not be aware of the term woodpeckering , but you've probably done it. It happens the day following a bad night's sleep. You're sitting in a long meeting and you can barely keep your eyes open, so you support your head up with your hand. Next thing you know, you are moving your sleeping head back to its upright position. Do this a few times and you are woodpeckering. I thought I knew sleep deprivation when I did my medical internship in hospital. That year I frequently went 36 hours with no sleep. When I finished my stay in neurology , I welcomed the promise of full nights of sleep ever after. It went pretty well for the next 10 years until I became a school teacher and experienced a whole new level of sleep deprivation. Teachers' working hours go far beyond the 8 am to 5 pm schedule of kids in school. There are hours spent at staff meetings, correcting homework, preparing for the next day- and then there is the worrying. What I did in a hospital emergency room required no more intensive mental energy than what is need to keep 30 kids attentive enough to learn what I was teacher. Good teachers are like magicians keeping a dozen balls in the air to come at right time, with alarm set for 6 am to finish grading papers, memories of the day that's gone- including the students who didn't understand something, forgot their lunch or were embarrassed by wrong answers. All these will become sleep-resistant barriers. And also with some financial stress, you'll have a cycle of insomnia with unwelcome consequences. With inadequate sleep comes irritability , forgetfulness, lower tolerance of even minor annoyances, and less efficient organization and planning. These are the very mental useless that teachers need to meet the challenges of the next day. In wanting to do a better job the next day, the brain keeps bringing up the worries that deny the rest it needs. Question: After a bad night's sleep, usually the direct effect for the next day is to _ . Options: A: keep one's eyes open all the time B: move head back and forth C: raise one's head in upright position D: keep nodding like a woodpecker

Read the article and select the best answer. Article: Hybrid cars are cars that run on petrol and electricity. They have a small standard petrol engine and a battery electric motor to provide electric power. There are some differences between different models of hybrid cars, but the general principle is that the car runs on petrol, and the electric motor kicks in when additional power is required, for example, when going uphill or accelerating. In some hybrid cars the petrol engine turns itself off when not needed, for example when the car has stopped at traffic light, keeping only the electric engine running. Conventional cars have large engines to deal with driving uphill and accelerating. Hybrid cars have much smaller petrol engines, improved by electric motors when needed, so they use less petrol. Another way that fuel consumption is cut is by a system of "regenerative braking". The electric motor is used to slow down the car, rather than conventional brakes. The energy produced by slowing the car is changed into electrical power, which is automatically stored in the battery. In effect, the battery recharges when you brake. In conventional cars the energy produced when braking is wasted. In 1928 Ferdinand Porsche built an experimental hybrid car. The first mass-produced hybrid car, the Toyota Prius, came out in Japan at the end of 1997. However, hybrid cars became available in the USA only in 1999. As they use less fuel, hybrid cars are cheaper to run. There are also many voices in place to encourage people to buy them. In some countries, hybrid car owners pay a lower rate of tax, and don't have to pay on certain roads. In some cities, hybrid cars are allowed to park for free. Question: Hybrid cars consume less energy than conventional cars because hybrid cars _ . Options: A: have large engines to deal with accelerating B: have conventional brakes to slow down the car C: have electric power to assist when needed D: have no energy consumption when stopping
