Memphis Meats, a San Francisco startup company trying to create lab-grown meat from animal cells(细胞), released a video on Tuesday that shows the world’s first cultured meatball getting fried up in a pan.
“We watched how the meatball reacted in the pan, we heard the sizzle, we smelled the meat and it was exactly how you would expect a meatball to smell,” Memphis Meats chief executive Uma Valeti said in the video. “This is the first time a meatball has ever been cooked with beef cells that didn’t need a cow to be killed.”
Memphis Meats grows animal muscle tissue(组织) using stem cells of cows and pigs and feeds them oxygen and nutrients(营养物质), according to the Wall Street Journal. While there are no animals killed in making the meats, the firm does use fetal bovine serum(胎牛血清) from unborn cattle's blood to start the process.
So far, the cells grow in extremely thin layers, which is very expensive. Now it costs about $18,000 to produce a pound of Memphis Meats beef--compared to about $4 for store-bought beef.
But the company, founded by three scientists, has been experimenting growing meat from stem cells from cows, pigs, and chickens and says it’ll be selling its animal-free products to high-end customers in three to four years.
The company’s first line of products will include hot dogs, sausages, burgers and meatballs.
Valeti said in the video that his company’s process also produces 90 percent fewer greenhouse gases than traditional agriculture.
“The meat industry knows their products aren’t sustainable(可持续的),” Valeti told the Wall Street Journal. “We believe that in 20 years, a majority of meat sold in stores will be cultured.”
It’s too early to say if we’ll all be cooking lab-grown meatballs, chicken wings, and pork chops. But for now, there is a big push to be the first to bring these foods to our plates.
1.What can be the best title for the passage?
A. Lab-grown meat is to hit the market.
B. Lab-grown meat smells as delicious.
C. Lab-grown meat is animal-free.
D. Lab-grown meat will replace traditional meat soon.
2.What’s the biggest disadvantage of the lab-grown meat?
A. It is difficult to grow.
B. It is too expensive.
C. It is difficult to be accepted by customers.
D. It doesn’t have many varieties.
3.What can we know about the lab-grown meat?
A. The layers where it grows are very expensive.
B. Cattle’s blood is needed to feed the cells.
C. Lab-grown meat has nothing to do with animals.
D. The growing process costs a lot.
4.What can we infer from the passage?

C. Lab-grown meat is environmentally friendly.
D. Lab-grown meat is best suitable for frying.

With a growing number of people in San Francisco choosing not to own a car, German carmaking company BMW has decided to branch out into car-sharing services with 70 cars spread around the city, first in 14 locations, with a further 100 being added gradually.
“This is not an A-to-A service — it is A-to-B,” says Richard Steinberg, chief executive of the DriveNow scheme (方案), pointing out that members can pick up a car downtown for the half-hour drive to the airport for only $12, compared with about $40-50 for a taxi.
Whether that is possible in real life depends on traffic, of course. A midmorning drive from Union Square down Highway 101 to the airport takes just 22 minutes; however, driving back during the rush hour takes twice as long.
Most of the cars that are stuck in San Francisco's traffic jams (交通阻塞) are giving off all sorts of harmful gas. But not DriveNow's BMW ActiveE cars.
“All the cars in San Francisco are electric,” Mr Steinberg says.
In San Francisco, handing back the car to DriveNow is easy — just pick one of its drop-off points, park and walk away. There are no forms to fill in, no time-consuming (耗时的) rules.
Several other carmakers and other players within the motor industry are experimenting with similar schemes, for example Daimler's Car2go scheme, which is operated in many cities around the world.
“We picture a future where car-sharing members outnumber car owners in big cities around the world,” says Car2go spokesman Andreas Leo.
Franck Leveque, from company Frost & Sullivan, agrees.
“Car sharing is growing at a pace we have not seen before,” he says. “By 2020 we believe there will be 15 million members of car-sharing schemes in Europe alone, with 140,000 vehicles in operation.”
1.What does the underlined part “branch out into” probably mean?
A. Start offering. B. Stop improving.
C. Make use of. D. Take control of.
2.The DriveNow scheme _____.
A. works better in rush-hour traffic
B. makes city driving less dangerous
C. encourages people to buy a cheap car
D. allows drivers to pay money to use a car
3.What's special about BMW ActiveE cars?
A. They drive much faster than other cars.
B. They never get stuck in heavy traffic.
C. They don't harm the environment.
D. They need less gas to run.
4.What does Franck think of the future of car sharing?
A. Worrying. B. Hopeful.
C. Uncertain. D. Disappointing.

A company in San Francisco, California, has found a way to turn used plastic bottles into women’s shoes.
Every day, millions of Americans drink water and other liquids from plastic bottles. More than 60 million of them are thrown away each day. Many of the plastic bottles end up in landfills or are burned with other waste products.
A San Francisco start-up company called Rothy’s, however, turns this plastic waste into environmentally friendly shoes. Rothy Martin is the company’s co-founder. He explains how they turn plastic into soft material for your feet. They take the plastic, clean it, and break it down into small pieces. Then they press it through a device that makes soft fibers. Those fibers are then combined, or knit together. This is done by a three-dimensional knitting machine. It is designed to reduce waste while making the shoes.
The knitted fabric and the inner part of the shoes are then attached to the shoes’ outer part, called the sole. This outer sole is also made from environmentally friendly material: responsibly sourced no-carbon rubber.
Rothy’s shoes are sold online. They are flat shoes, with either a rounded or pointed toe. They come in different colors and designs. They cost either $125 or $145 per pair, depending on the design.
After American actress Gwyneth Paltrow discovered them last year, the demand for the shoes grew.
Martin says there is no shortage of material to fill that demand. “We’re not going to run out of water bottles any time soon. So we have an infinite supply of material, and I think that bodes well for our future. ”
When the environmentally friendly shoes wear out, customers can return them at no cost to a company that uses the recycled materials to make other products.
For now, the shoes are only available to be shipped in the United States. However, the company says it will add international shipping in the near future.
1.Which one is the right procedure of making shoes?
①pressing small pieces
②breaking down clean plastic bottles
③knitting together
④cleaning plastic bottles
⑤attaching the knitted fabric, the inner part and the outer part
A. ①②③④⑤ B. ④②③①⑤
C. ④②①③⑤ D. ②①③④⑤
2.Why did Rothy’s use a three-dimensional knitting machine to make shoes?
A. Because it is easy to operate.
B. Because it is cheaper than other machines.
C. Because it is productive.
D. Because it can reduce waste when making the shoes.
3.What can be learned from the passage?
A. This kind of shoes are sold in the shop.
B. The shoes are environmentally friendly.
C. Customers can return them with little money to a company.
D. The shoes are available in the world.
4.What’s the best title of the passage?
A. How to recycle plastic bottles
B. Recycled bottles find newlife on women’s feet
C. How a new kind of shoes became a hit

San Francisco, a leader in urban recycling, is preparing to turn dog waste into energy.
Norcal Waste System Inc., the city’s largest garbage company, plans to test collection carts(回收车)and collection bags in a city-center park which is popular with dog walkers.
A city study found that almost 4 percent of all the garbage picked up at San Francisco homes was from animal waste, Norcal Waste spokesman Robert Reid said. San Francisco has about 120,000 dogs.
“The city asked us to start a program to recycle dog waste in order to cut back adding more waste in landfills(废渣埋填池) “,Reid said.
Dog waste will be poured into a methane digester(沼气池),and the methane it gives off will be collected and burned to make electricity or to heat homes.
“Dogs and cats in the United States produce about 10 million tons of waste a year,” Will Brinton, an environmental scientist said.
“As much as we love them, our pets leave a lot of fertilizer behind them in yards and on the street but that can be a major source of contamination of groundwater,” Brinton said.
European cities such as Zurich, Frankfurt, Munich and Vienna are starting biology programs to turn waste into gas ,he said.
San Francisco runs a great program to recycle bottles, cars, paper and other rubbish and now two-thirds of its garbage needn’t be carried to landfills .The city’s goal is a 75 percent drop by 2010 and zero new waste in landfills by 2020.
1.San Francisco will plan to use dog waste for making __________.
