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(空氣動力的) 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

China has the highest adoption rate in the world for technology-enabled payment systems, according to a report released on Wednesday. The report, from the market research firm Nielsen, is based on a survey of 13,000 respondents in 26 countries.

The survey showed that 86 percent of Chinese respondents said they paid for online purchases during the past six months via digital payment systems compared with a global average of just 43 percent.

"Chinese consumers have more payment choices for products and services than ever while digital payments will continue to win over more Chinese consumers due to its convenient nature," said Kiki Fan, managing director of Nielsen China.

The increasingly popular payment method is part of the rapidly evolving purchasing behavior of Chinese consumers. About 98 percent of the respondents in China, the world's largest e-commerce market, said they had made purchases online.

The majority of them still make online purchases via computers, but the number of those who use mobile devices to make purchases is growing fast and is significantly higher than the average in other surveyed countries.

At 71 percent, food-related businesses topped the list of purchases made via smart phones while event ticket purchases stood at 51 percent.

The rising use of digital payments has attracted numerous players to the Chinese market.

Apple Inc launched its contactless payment system Apple Pay in the Chinese mainland last month. It allows users of the iPhone 6 or more advanced versions, certain iPads and Apple Watches to pay by their devices in bricks-and-mortar stores.

Apple's rival Samsung Electronics Co Ltd is expected to bring its own mobile payment service to China in mid-March—Sam-sung Pay.

China's Internet giants Alibaba Group Holding Ltd and Tencent Holdings Ltd have already taken about 90 percent of the mobile payment market, but industry observers said the competition is just about to start.

If you’re encouraged by the tiny house movement and think 160 square feet is just enough for your needs, you may want to contact the Academy of Construction and Design (ACAD) at IDEA Public Charter School in northeast Washington.

Students in the program built a micro house with a kitchen, a bathroom, a sleeping loft with space for a queen-size bed and a storage loft, all set on a trailer for mobility. The exterior of the house was part of a continuous living exhibit in 2015 and was moved to the IDEA campus so students could work with builders to complete the interior earlier this year.

McMahon said the D. C. government’s approval to push companies to hire District residents was at odds with the school system not preparing students for careers in construction, exploring or electrical work. McMahon gathered industry and community leaders to establish ACAD in 2005, and he said 100 percent of the companies he contacted responded positively to the idea, including major firms such as JBG, Clark Construction, Hines Construction and Boston Properties.

“When students make the connection between what they are learning a potential career, their academics improve dramatically,” said Carol Randolph, chief operating officer of the D. C. Students Construction Trades Foundation. “Some of them who didn’t think college was an option now have a better chance because their classes have become relevant to a job.”

“We teach them life skills and explain that even if you start as a laborer, there are opportunities to move up quickly,” he said. “We rewrite the story for them and explain that they can work for a few years, make good money, get promoted, and start their own business or go to school with less debts.”

“Parents and school advisor can be the biggest obstacles because of the negative idea of construction as a blue-collar career,” Karriem said. “I get middle-school advisor on board to talk about the opportunities this education provides. These kids are learning lifelong skills that can help them in other fields, provide them with income and allow them to take care of their homes.”

1.What might be the main purpose of the first paragraph?

A. To advise the students to build houses.

B. To show IDEA Public Charter School.

C. To introduce the tiny house movement.

D. To get in touch with the ACAD organization.

2.What is the program of building a micro house aimed at?

A. Experiencing living in the tiny house.

B. Improving cooperating with related companies.

C. Learning lifelong skills from college classes.

D. Providing the opportunities to get a job.

3.What does the underlined part “at odds with” mean in the 3rd paragraph?

A. Inconsistent B. Favorable

C. Unusual D. Satisfactory

4.What can we infer from the words of Karriem?

A. Students tend to choose the blue-collar career.

B. It’s hard to make the micro house movement popular.

C. Education should provide more job opportunities

D. Life skills help improve students’ academics greatly

It’s always important to use the right tools for any job. Success in school is no different. If you need to vary your time management tool box, consider these less traditional tools. 1..

Daily Task List

A daily task list is nothing more than a notepad that you use to list your daily goals. 2.. Cross them off as you finish them. At the end of each day, simply carry over any job that you didn’t finish to the next day’s list. It works wonders!

Big Well Calendar

Simply place the big wall calendar in a prominent place near your regular study space. Then come up with a color code for your classes(like green for math and yellow for history). When you have a big due date or a test date, place the appropriate colored sticker on that date. 3., so it works as a constant reminder. This trick is simple, cheap, and so effective!

Sticky Note Flags

4., whether you’re putting together a big research project or you’re simply reading a book. Whenever you need to remember to take a certain object or assignment to school, place a sticky flag on the door knob, bathroom mirror, or the cereal box the night before. It works like an alarm!

Bedside Notepad

You can keep a notepad beside your bed to write down any items or tasks you have to remember for the next day. As you settle in for the night, take a few moments to think about the things you need to do tomorrow. Then write them down and tear off the sheet in the morning. 5.!

A. Remember to pack it in your schoolbag.

B. Keep your homework and your life in order

C. Two heads are better than one when it comes to projecting due dates

D. You could also use the calendar feature to alert you when projects are due

E. These little paper banners are lifesavers when it comes to getting organized

F. Carry a small pad around and write down every task you need to complete

G. The sticker will be something you can see every time you enter the room.

Tins of cooling ointment (清涼油) have become a currency for Chinese traveling in Egypt.

1.(visit)the complex of ancient temples at Karnak, Chinese tourist Mr. Ye lost his way among the stone churches and pillars.

An Egyptian guide gave him directions. To show his 2.(appreciate), Mr. Ye handed him a small red tin the size of a large coin. Inside 3.(be) a cooling ointment that has the function of refreshing mind and preventing pain. Mr. Ye brought 50 tins with him on his six-day tour to hand out as tips.

"Before I came to Egypt, the tourism agency told me 4.(repeat) to bring cooling balm as a gift to make the trip 5.(easy)," said Mr. Ye, a 25-year-old 6.family sells Chinese medicine online. Egyptians, he said, are very nice to Chinese tourists, 7.they love this little gift."

“Go to get help, quick!”I ordered my six-year-old brother Nicholas. Nicholas ran away, when I slipped onto the ice.

I moved towards the hole where the three boys fell. I reached my hand in but felt nothing. I put my face in to see if I could see anything, but I saw nothing .So I decided to go in.”Ah!”I screamed as I fell in the cold water. I saw Conner face down in the water. I caught him by the arm and pushed him to the surface. He lost his consciousness. I went down again with two hockey sticks(曲棍球球棍）this time, I saw Wilson searching for something to hold. I quickly swam to him, and he caught hold of my hand. When we finally came to the surface, Wilson became unconscious too. Morgan was left. I didn’t see him. I was about to give up when I saw him about fifteen feet away. I caught him, but his foot was caught in some weed. I managed to pull his leg free. I grabbed the hockey stick, but I was out of breath. I hit the ice with the stick with all my strength. Finally, it broke. I never thought I’d see the sun again! I brought Morgan to the surface, where firefighters had already saved Wilson and Conner.

The next thing I knew was that I was in hospital.“Hi, my boy, you could have died,” cried my mom.“Hi, mom,” I said.“They were going to die if I didn’t help them, and the nearest help was about a mile away. How are the boys?” “Everyone is OK. You are our hero,” said my father.

I won the Hero prize from my town for saving the boys. Now we are all best friends.
