Antaretica’s ice-white environment is going green and facing other unexpected threats. Scientists say that as temperatures go up in the polar region, invading (入侵) plants and insects, including the flies, cause a major conservation threat.

More and more of these invaders, in the form of larvae (幼虫) or seeds, are surviving in coastal areas around the South Pole, where the temperature has risen by more than 3℃ over the past three decades. Glaciers have retreated, exposing more land which has been occupied by mosses that have been found to be growing more quickly and thickly than ever before-providing potential green homes for invaders.

“The common house flies are a perfect example of the problem the Antarctic now faces from invading species,” said Dominic Hodgson of the British Antarctic Survey. “It comes in on ships, where it exists in kitchens and then at bases on the continent. It now has an increasing chance of surviving in the Antarctic as it warms up, and that is a worry. Insects like the house flies carry bacteria that could have a deadly effect on native lifeforms.”

The Antarctic has several native species of insects. Together with its native mosses, these are now coming under increased threat from three major sources: visiting scientists, increasing numbers of tourists and global warming. However, it is global warming that is the main driver of the greening of Antarctica.

In 2015, more than 38,000 tourists visited Antarctica. “These tourists are often very careful about not leaving waste or having mud. But they could carry seeds or larvae on their boots when they set foot on the Antarctic,” said Hodgson.

More and more invasive insects and plants have been found on the Antarctic and have required removal. “the insects and plants that are native to Antarctica have survived these for thousands of years,” said Hodgson. “We have got to act now if we want to save the environment.”

China is going green. In order to reduce air pollution and oil shortages, automobile manufacturers have announced their plans to develop hybrid vehicles (混合燃料汽车) for the Chinese market. Toyota's hybrid car Prius will be ready to drive in China this week. Let's have a look at the new car.

Any vehicle is a hybrid when it combines two or more sources of power. Hybrid cars run off a rechargeable battery and gasoline. Hybrid cars have special engines, which are smaller than traditional gasoline engines. They run at 99 percent of their power when the car is cruising (匀速行驶). A specially designed battery motor provides extra power for running up hills or when extra acceleration is needed.

Step into a Prius, and turn on the engine. The first thing you notice is how much quieter it is than a traditional car. At this point, the car's gasoline engine is dormant (休眠). The electric motor will provide power until the car reaches about 24 km/h. If you stay at a low speed, you are effectively driving an electric car, with no gasoline being used, and no waste gas gives off.

The onboard(车载的) computer makes the decision about when to use a gas engine, when to go electric, and when to use a combination of the two. If you go over 24 km/h, when you step on the gas pedal (油门), you are actually telling the computer how fast you want to go.

The electronic motor recharges automatically using a set of batteries. When driving at high speed, the gasoline engine not only powers the car, but also charges the batteries. Any time you use the brake, the electric motor in the wheels will work like a generator and produce electricity to recharge the batteries. As a consequence, the car's batteries will last for around 200,000 miles.

1.The author writes this passage mainly to________.

A. teach people how to drive a hybrid car

B. show how to save their gasoline when driving a car

C. introduce a new kind of "green" car

D. announce plans to develop hybrid vehicles for China

2.The first sentence probably refers to ________.

A. there will be more and more green land in China

B. China has started producing environmentally friendly cars

C. China's new cars are combinations of different green models

D. China is still young and lacking experience

3.What is the most important feature of hybrid cars?

A. They have smaller engines than traditional gasoline ones.

B. They are much quieter than traditional cars.

C. They only use 99 percent of their power to run up hills.

D. They are powered by both a rechargeable battery and gasoline.

It is made from grapes grown without pesticides (杀虫剂) and chemicals, is kind to the environment and rarely causes hangovers (酒后头痛). Sales of organic wine are booming in the UK.

According to the organic food and farming group Soil Association, sales of organic beers, wines and spirits rose by 14.3% last year to reach nearly £ 6 million, driven by the demand from consumers who are increasingly seeking “natural” food.

“It seems that people are rediscovering their link with the environment through organic food. Organic wines also taste better, perhaps due to less use of man-made chemicals.” said Finn Cottle of Soil Association. As well as the benefits of producing grapes without using pesticides, organic wine also contains less sulphur dioxide (二氧化硫), which can contribute towards hangovers.

Supermarkets are increasing supplies on their shelves to meet consumer demand, while the switch to online shopping has also helped, as people are more easily able to find what they are looking for. Vintage Roots is now one of the UK’s biggest online shops of organic wine, while Ocado provides more than 100 different organic wines and Daylesford, best-known for its organic vegetable boxes, has branched out into organic wine and spirits.

The discount supermarket Aldi is set to start its first collection of so-called “green” wines this week, offering eight wines with organic certificates. Aldi expects the wines to appeal to the young shoppers who are increasingly concerned about the environmental influence of the produce that they are buying and consuming.

English organic wine producer Oxney Estate’s Noir Rosé recently won the Waitrose prize for the most outstanding rosé wine at the competition. A spokeswoman for Waitrose said: “Organic wine is a growing trend globally and we have seen sales increase by 16% in the last year”.

1.Sales of organic wine are increasing probably because ________.

A. consumers are now more environmentally aware

B. it offers a very different taste from traditional wine

C. consumers are tired of hangovers after drinking

D. it contains no sulphur dioxide or pesticide

2.What’s the main idea of paragraph 4?

A. UK supermarkets welcome organic wine and spirits.

B. Online shopping promotes the sales of organic wine.

C. There’re not enough supplies of organic wine in the UK.

D. Supermarkets should go online to sell more wine.

3.“Waitrose” in the last paragraph is probably ________.[

A. a wine producer　　 B. an organic wine

C. a wine competition　　 D. a news agency

4.The writing purpose of the text is to ________.

A. persuade readers to go green while drinking
