Why do human beings still risk their lives under ground and doing one of the dirtiest and most dangerous jobs in the world? It is an increasingly urgent question, given the recent mining accidents in Sago, W. Va and Huntington, Utah. A small group of engineers and robotics experts look forward to a day in the not-too-distant future when robots and other technology do most of the dangerous mining work.
Robotic technology, in particular, holds much promise, McAteer says, especially when it comes to mapping mines and rescuing trapped miners—the special operations of the mining industry.
One of the first mining robots was developed five years ago at Carnegie Mellon University's Robotics Institute. It was called Groundhog. It used lasers(激光器) to “see” in dark tunnels and map abandoned mines—some of the most dangerous work in the business.
The latest design is called Cave Crawler. It's a bit smaller than Groundhog，and even more advanced. It can take photos and videos and has more sensors that can detect the presence of dangerous gases. Incredibly，the robot has a real sense of logic. If it comes across an obstacle it gets momentarily confused. It has to think about what to do and where to go next. Sometimes it throws_a_fit just like a real person.
The greatest problem, though, is cost. The money of the earliest research project was provided by the government, but that money had dried up, and it's not clear where future money will come from. Partly for that reason, and partly because of advances in safety, mining is not nearly
as dangerous as it was in the past. Since 1990, fatalities(致命性) have declined by 67% and injuries by 51%, according to the National Mining Association.
Some experts predict that robots in mines will serve much of the same function that they do in the automotive industry. The robots do the most boring and dangerous jobs，but won't get rid of the need for human workers.
1．The latest robot is more advanced than Groundhog, mainly because ________.
A．it can map abandoned mines B．it has a real sense of logic C．it can see in the dark tunnels D．it's smaller than Groundhog
2．The underlined phrase “throws a fit” in paragraph 4 probably means “________”．
A．gets sick B．gets angry
C．becomes hungry D．becomes cheerful
3．We can infer from the last paragraph that ________. A．the mine robots will have a very bright future
B．robots in mines will serve much in the automotive industry C．there will be no need for human workers in mines D．robots in mines only do some simple jobs now 4．We can infer from the text that ________. A．robots cannot do dangerous work in dark areas B．the mining robots do most of the mining work at present
C．groundhog can discover the presence of dangerous gases D．experts are trying to make robots help miners with dangerous work
答案与解析
文章介绍了一种新研发的机器人，和以前的Groundhog相比，它有真正的逻辑能力，最重要的是，它可以帮助矿工们做一些危险的事情。
1．B 从文章第四段的句子：Incredibly，the robot has a real sense of logic.可知最新的机器人比Groundhog更先进，因为它有真正的逻辑能力，故选项B正确。
2．B 从第四段的句子：If it comes across an obstacle it gets momentarily confused.Sometimes it throws a fit just like a real person.有时它会像真人一样生气，可知“throws a fit”意思是“生气的”，故答案选B。
3．A 从最后一段的句子：Some experts predict that robots in mines will serve much of the same function that they do in the automotive industry.可知矿场机器人有更光明的未来，故答案A正确。
4．D 从文章第一段的句子：A small group of engineers and robotics experts look forward to a day in the not-too-distant future when robots and other technology do most of the dangerous mining work.可知这篇文章讲的是研究人员正研究在矿场工作代替工人做危险的工作的机器人，故答案D正确。

It's normal to wake briefly during the night. __1__ But if you're
waking up during the night and having trouble falling back asleep，the following tips may help.
Stay out of your head. The key to getting back to sleep is continuing to prepare your body for sleep，so remain in bed in a relaxed position. Hard as it may be，try not to stress over the fact that you're awake，because that very stress and anxiety encourage your body to stay awake. __2__ __3__ If you are finding it hard to fall back asleep，try a relaxation technique such as visual-ization(想象), or deep breathing，which can be done without even getting out of bed. Remind yourself that although they're not a replacement for sleep，rest and relaxation still help refresh your body.
Do a quiet, non-stimulating activity. If you've been awake for more than 15 minutes, try getting out of bed and doing a quiet，non-stimulating activity，such as reading a book. Keep the lights dim so as not to think that it's time to wake up. __4__ A light snack might relax you，but be careful not to eat so much that your body begins to expect a meal at that time of the day.
__5__ If you wake during the night feeling anxious about something，make a brief note of it on paper and delay worrying about it until the next day when you are fresh and it will be easier to resolve.
A．Make relaxation your goal，not sleep. B．Put off worries and troubles.
C．Use a flashlight to go to the bathroom at night. D．In fact，a good sleeper won't even remember it.
E．Also avoid screens of any kind—computers，TVs，cell phones，
iPads.
F．You'll be much more productive and creative after a good night's rest.
G．A good way to stay out of your head is to focus on the feeling in your body.
