The auto industry, aviation (航空) giants and lots of new companies are increasingly entering the race toward producing flying cars and air taxis, many of which are said to be fully electric. On the surface, there are so many innovations happening that it’s easy to forget that the world hasn’t even seen a fully autonomous car yet, let alone an electric flying vehicle you can park in your driveway.

In fact, there are several hurdles before people are riding through the air. “They are short on technology, and they are short on regulation.” said Jennings-Bates, vice president of a car company.

Uber and Boeing, both world famous companies, have announced ambitious plans for air taxis. However, the types of vehicles they have in mind would require magical electric batteries that don’t exist yet.

Whether the United States actually needs flying cars remains relatively unclear. Aviation experts say that air vehicles help solve congestion problems in big cities. “Today, we have a lot of traffic congestion on the roadways,” said Laurie Garrow, associate director for the Center for Urban and Regional Air Mobility at Georgia Tech. “Air taxis would provide a solution for that.” Others argue that putting traffic in the skies doesn’t solve very much. “We aren’t going to change the world in terms of traffic with flying cars,” said Jennings-Bates. “At best, it may take the place of traffic in the area, which is arguably less pleasant.”

Some experts say it’s not a question of whether flying cars will take off. Instead, it’s a question of how soon the concepts would be safe enough for humans to occupy. “Everyone is very excited and they’re coming up with very different designs,” Garrow said. “But you have a lengthy certification process that will need to go through to make sure the craft and flights are safe.” She estimates that it’ll be about 20 years before the U.S. sees more than test flights.

1.What can we infer about flying cars from Paragraph 1?

A.They are fully electric. B.They are unavailable yet.

C.They need special driveway. D.They equal autonomous cars.

2.What does the underlined “hurdles” in Paragraph 2 refer to?

A.Ambitious plans. B.Big problems.

C.Electric batteries. D.Current innovations.

3.According to Garrow, what’s the main concern about flying cars?

A.Test flights. B.Design.

C.Production. D.Safety.

4.What does the text mainly talk about?

A.Why we should produce flying cars. B.How hard the race of making flying cars is.

C.How close we are to seeing flying cars. D.What people’s opinions are about flying cars.

The global energy crisis is approaching. What can we do? Here are some steps you can take.

Cooling puts the greatest stress on your summer energy bill and the power grid. Just as a tune-up for your car can improve your gas mileage, a yearly tune-up of your heating and cooling system can improve efficiency and comfort. Clean or replace filter monthly or as needed.

For central air conditioning systems and room air conditioners, look for the ENERGY STAR, the federal government’s symbol for energy efficiency. For central air, purchase the system with the highest possible Seasonal Energy Efficiency Ratio. (SEER)

Use energy efficient ceiling fans either alone or with air conditioning. Ceiling fans do a great job of circulating air. When used with air conditioning, fans allow you to raise the thermostat and cut costs. Ceiling fans cool people, not rooms, so before you leave, turn off the ceiling fan.

Let a programmable thermostat “remember for you” to automatically adjust the indoor climate with your daily and weekend patterns to reduce cooling bills by up to 10 percent. You can come home to a comfortable house without wasting energy and creating pollution all day while you are at work.

Try to make your home airtight enough to increase your comfort, make your home quieter and cleaner and reduce your cooling costs up to 20 percent.

Cut your air conditioning load, and reduce pollution by planting leafy trees around your home and fixing reflective bricks on your roof.

Close blinds or shades on south-and west-facing windows during the day, or fix shading equipment to avoid heat build-up.

Turn off everything not in use: lights, TVs, computers. And use fluorescent bulbs, which provide bright, warm light while using at least two-thirds less energy, producing 70 percent less heat and lasting up to 10 times longer than incandescent bulbs.

Drive the car that gets better gas mileage whenever possible if you own more than one vehicle. If you drive 12,500 miles a year, switching 10 percent of your trips from a car that gets 20 miles per gallon to one that gets 30 mpg will save you more than £65 per year.

Carpool. The average U.S. commuter could save about £260 a year by sharing cars twice a week with two other people in a car that gets 20.1 mpg-assuming the three passengers share the cost of gas.

1.According to the passage, the thermostat is used to ________.

A.make rooms quieter B.control room temperature

C.turn off the air conditioner D.reduce room air pollution

2.We can conclude from the passage that the author probably discourages _________.

A.planting leafy trees around your home

B.turning off the ceiling fan before you leave your house

C.keeping your south-facing windows open during the day

D.using fluorescent bulbs instead of incandescent bulbs

3.According to the passage, you can save fuel by _______.

A.using energy-efficient ceiling fans

B.sharing cars with others on workdays

C.turning off everything not in use

D.reducing 10% of your car trips every year
