Electric cars are dirty. In fact, not only are they dirty, but they might even be more dirty than their gasoline-powered cousins.
People in California love to talk about “zero-emissions (排放) vehicles”, but people in California seem to be clueless about where electricity comes from. Power plants mostly use fire to make it. Apart from the few people who have their roofs covered with solar cells, we get our electricity from generators (发电机). Generators are fueled by something----usually coal, oil, but also by heat generated in nuclear power plants. There are a few wind farms and geothermal (地热) plants as well, but by far we get electricity mainly by burning something.
In other words, those “zero-emissions” cars are likely coal-burning cars. Because the coal is burned somewhere else, it looks clean. It is not true. It's as if the California Greens are covering their eyes----“If I can't see it, it's not happening.” Gasoline is an incredibly (极其) efficient way to power a vehicle; a gallon of gas has a lot of energy in it. But when you take that gas (or another fuel) and first use it to make electricity, you waste a nice part of that energy, mostly in the form of wasted heat--at the generator, through the transmission lines, etc.
A gallon of gas may drive your car 25 miles. But the electricity you get from that gallon of gas won't get you nearly as far---so electric cars burn more fuel than gasoline-powered ones. If our electricity came mostly from wind or geothermal, or solar, then an electric car truly would be clean. But for political, technical, and economic reasons, we don't use much of those energy sources.
In addition, electric cars' batteries which are poisonous for a long time will eventually end up in a landfill (垃圾填埋场). And finally, when cars are the polluters, the pollution is spread across all the roads. When it's a power plant, though, all the junk is in one place. Nature is very good at cleaning up when things are not too concentrated, but it takes a lot longer when all the garbage is in one spot.
1.Which of the following words can replace “be clueless about” in Paragraph 2?
A. be familiar with. B. fail to understand.
C. be curious about. D. show their interest in.
2.The electricity we get from a gallon of gas may make our car run _________.
A. at least 25 miles B. more than 25 miles
C. less than 25 miles D. as far as 25 miles
3.In the author’s opinion, compared with cars using gas, electric cars are more __________.
A. harmful B. expensive
C. efficient D. environmentally-friendly
4.It can be inferred from the passage that __________.
A. electric cars’ batteries are no longer poisonous in the landfill
B. electric cars are not clean since we get electricity mainly by burning something
C. zero-emissions vehicles should be chosen to protect our environment
D. now electric cars are used more than their gasoline-powered cousins
Art is an important part of education, not only on its own but in the rest of education as well. However, in this information age, advanced technology in school has gained more attention than art. Sometimes when the school has a tight budget, it is usually art rather than technology that becomes the first thing to be cut.
Anyway, the significance of art can’t be ignored. First of all, in school it can help students develop a variety of life skills such as communication skills, problem-solving skills and self-expression skills. Secondly, for high school students, those who are involved in arts classes can have higher test scores. Besides, for some students, art seems to be motivation for coming to school because it’s a subject that they can outshine, which eventually balances their educational experience.
New technology surely offers many benefits to some aspects of education, making teaching and learning easier and more effective. For example, technology simplifies tasks that take much longer to do, like conducting research or finding information. But advanced technology has bad effects such as the risk of being overweight, tiredness and even potential mental health problems, while art doesn’t. On the other hand, unlike art, no technology can develop students’ critical (批判的) thinking skills and a creative mind, both of which can help them to find successful careers after they graduate. Furthermore, no technology can help students to learn to bear responsibility, develop their imagination and increase their confidence.
Generally, art should not be replaced with advanced technology in schools and the last thing to be cut out of school curriculum.

How to Survive Embarrassing Moments
Have you ever done something embarrassing? At that moment, you probably wished you could disappear into thin air. Unfortunately, embarrassing things happen to everyone at one time or another. The good news? You can keep the damage to the minimum．Here's some help．
Laugh it off
You're staring at your crush （意中人） so hard that you walk into a wall．You trip over your own feet and drop all your books．The best thing you can do? As long as you're not seriously hurt, laugh it off．Say like "Hey, I can teach you to do that if you want to!" or "It took me years to learn that!" By laughing at yourself, you show people you're confident and still in control of the situation．That's bound to make a stronger impression than the fact that you dropped a stack of books．
Move on
Some situations are too personal to laugh off．Your underwear falls out of your backpack. Your bathing suit falls off in the pool．You pass gas while giving a presentation．Making a joke would just call more attention to what happened — and that's the last thing you want．What now? You can just pretend nothing happened and go back to what you were doing, or you can acknowledge it with a "Oh, that was awkward" and then move on．
If there's a joker who thinks it's a good idea to point out how badly you just embarrassed yourself, fix him with a glare and then go back to whatever you were doing．Tell yourself he's a little bug on the ground, not even worth thinking about．Remind yourself that it's over, done．Move on．
Apologize and move on
Some embarrassing situations pack a double punch．Not only do you embarrass yourself, but you make someone else feel bad．You say to a friend that another friend is such a copycat, and then realize the copycat is standing right behind you．You imitate your teacher's unusual accent just as the teacher walks in．Now you're embarrassed and they're mad or hurt．
Making a joke now would make the situation even worse, so don't go there．Although you might feel like running away or even crying, neither of those responses will make you look better．Instead, apologize, "I'm so sorry．That was really mean of me．"
If you've been disrespectful to a teacher or a parent, accept whatever consequences without complaint．If you've hurt a friend, do your best to make it up to them．Once you've done all you can to make things right again, move on．If someone else brings it up, just say, "I feel bad enough about that —can we just let it go, please?"
The next time you're stuck in an embarrassing moment, remind yourself that you're a strong person and you can get through this．Stay calm and act confident and the moment will pass．
