It encouraged us to visit Quora.com, the online question and answer community, to find out how users get the most out of every tank of gas.
Light makes right
Alex Elderfield noted that excess weight prevents an engine from burning fuel efficiently. "Only carry what is essential in your car, clean out any junk or necessary items otherwise you are paying for the fuel to cart these from place to place," he wrote.
Driving smoothly — that is, not mashing the gas and then slamming the brakes later down the road — was a fixture of many responses. Quora user Clint Law agreed on that advice, who wrote, "Every little bit of kinetic energy that your brakes lose, your engine burned in fuel to build up." Overbraking should consequently be viewed as wasted acceleration. "That's really what kills your fuel economy," he argued.
Keep the pressure up
Keeping the recommended tire pressure for your car was another mantra among Quora users. Marlyn Rosent said she checked her tire pressure every time she filled up her SUV. Quora user Doug Dingus checks his tire pressure every weekend. “Less tire contact means reduced rubbing, requiring less fuel,” he said.
Air conditioning or windows
Though the summer heat get many drivers to roll up the windows and turn on the air conditioning, some people argued that running the A/C wastes too much gas. In between were many shades of grey.
Achilleas Vortselas said it would depend largely on a car’s speed. He wrote that as a general rule, people should drive with the windows down around the city and turn the air conditioning on when hitting the highway, where a car’s aerodynamic(空气动力的) characteristics would be influenced by opened windows.
More seriously minded people, however, said to travel as much as possible with windows up and the A/C off. Eddie Xue gets by with just a wisp of outside air. “Use the fan and open your windows every now and then at lower speeds," he wrote.
1.What can we learn from what Clint Law wrote?
A. Overbraking is a waste of gas.
B. Carry what we need in the car.
C. Build up energy to drive smoothly.
D. Stepping on the gas freely can keep a balance.
2.What do we know from Doug Dingus’ words?
A. Checking tire pressure will require less fuel.
B. Filling up the SUV leads to reduced rubbing.
C. Keeping the recommended tire pressure is necessary.
D. Braking fiercely can keep wasting acceleration.
3.The author says “In between were many shades of grey” to indicate that ________.
A. rolling up the windows and turning on the air conditioning waste too much gas
B. people should try their best to travel with windows up and the A/C off
C. when a car approaches higher speeds, the A/C should come on
D. there’s balance between the air conditioning and windows usage
4.Which is the suitable title of the passage?
A. Fuel efficiency, straight from source
B. Driving with the windows down and using the A/C
C. How to save at the pump this summer
D. Reducing the weight and increasing the vehicle’s fuel economy

My Uncle Dave posed an interesting question to my wife and me when he came to visit us the other day. He asked: “What do you think the world will be like in 50 or 100 years, in terms of technology and society and so on?”
He says he asks many of the people he meets this question to see what their thoughts are. His point is that no one really knows. I mean, in 1945, could people have even imagined surfing the net or sending e-mails as we do? No way. And the pace of technological innovation(创新) is incredible (难以置信的). We’re on a more different curve than we used to be.
One thing I’m looking forward to is real software agents. There is so much information out there, but I want something that can help me find what I really want. For instance, in about ten years, I think, there will be no longer recorded music, and there will be some big databases from which you can download music onto your hard drive or whatever. At that point, there will be so much music to choose from and you’ll be able to sample things before you buy them. But the question will be how I find what I’m looking for and how I do find the music that might interest me. Or more generally, how do I find information that I want without spending all the time myself surfing the net? How do I find people who are like-minded (具有相似目的), with whom I might really want to communicate? I want to find those people but it’s hard to do. In the future I think that one will be able to build a community of like-minded people who live all over the globe. It’s going to be very interesting, I think.
1.No one really knows what the future will be like because _____.
A.there is too much information for us to choose from |
B.technological development is too fast |
C.people live in different countries |
D.no one is intelligent enough to answer such a question |
2.The function of the first paragraph is to _____.
A.explain the question given in this paragraph |
B.put forward the topic in this passage |
C.show Dave is a foolish man to ask such a question |
D.describe a picture about what the future will be like |
3.The writer is looking forward to some real software agents so as to _____.
A.earn a lot of money |
B.communicate with some like-minded people |
C.help find the correct information needed |
D.spare some time for surfing the Internet |
4.The best title of this passage should be _____.
A.What the Future Will Be Like |
B.Listen to Music Through the Internet |
C.Music and Software Development |
D.How to Live a Happy Life in the Future |

Every day we go to school and listen to teachers, and the teacher will ask us some questions. Sometimes, the classmates will ask your opinions of the work of the class. When you are telling others in the class what you have found out about these topics, remember that they must be able to hear what you are saying. You are not taking part in a family conversation or having a chat with friends --- you are in a situation where a large group of people will remain silent, waiting to hear what you have to say. You must speak so that they can hear you loudly enough and clearly enough but without trying to shout or appearing to force yourself.
Remember, too, that it is the same if you are called to an interview whether it is with a professor of your school or a government official who might meet you.

It has become a habit for many of us. When you're tired of online shopping, you head to the bathroom to do your best makeup for the perfect selfie(自拍)for Facebook, Instagram, Snapchat or all of the above. When you're ready, you hold up your phone and, in an instant, snap(拍照)。
But have you ever wondered what's behind your burning desire to self-document?Most people would say that this is a way to express themselves and perhaps make them become more confident of themselves. But the moment you upload that picture, it's no longer yours to judge. Instead, you pass on that power to the online world.
While you may think that your growing collection of selfies attracts people, quite the opposite may be true. A recent study was conducted on a total of 238 people in Austria, Germany and Switzerland. 77%of the people surveyed admitted to regularly taking selfies. Interestingly, 82% of people said that they would rather see fewer selfies on social media. In other words, we like taking selfies but seriously dislike looking at other people's selfies online.
This research finds that there is a big difference between how we see our own selfies and how we judge other people's pictures. It suggests that we are comfortable with the selfies we post since we believe they are obviously not serious or vain, but we think everyone else is an egoist(自我主义者)for doing the very same thing. After all, we are able to separate our own selfies from the sea of them online and naturally think that ours are the only authentic ones.
So, the next time you reach for your phone and take a selfie picture, consider this: The people around you may not need another carefully planned snap of your face. Instead, you might be better off, giving it a break and calling off the selfie photo today. While you're at it, make sure you never post these pictures on social media either.
1.What is most people's idea on taking their own selfies according to the text?
A.It's a good way to keep others informed of their life.
B.It costs less money than shopping online for makeup.
C.It's a way of self-expression and building confidence.
D.It can help them keep a record of their daily routines.
2.How do other people feel about our online selfies that we consider attractive?
A.They actually take great interest in them.
B.They envy our life after appreciating them.
C.They are likely unwilling to see them online.
D.They hardly make annoying reviews on them.
3.Why do we regard others as egoists for taking selfies?
A.They are not serious but vain in nature.
B.We don't think their selfies are authentic.
C.We are too proud to acknowledge others.
D.They hate getting their selfies polished.
4.What is the last paragraph mainly about?
A.Approaches to resisting taking selfies.
B.Concerns over posting selfies online.
C.Doubts about contradictory thoughts.
D.Suggestions on dealing with selfies.
