Electric cars are dirty. In fact, not only are they dirty, they might even be more dirty than their gasoline-powered cousins.People in California love to talk about “zero-emissions(排放)vehicles”, but people in California seem to be clueless about where electricity comes from. Power plants most all use fire to make it. Apart from the few people who have their roofs covered with solar cells, we get our electricity from generators(发电机). Generators are fueled by something--usually coal, oil, but also by heat generated in nuclear power plants. There are a few wind farms and geothermal(地热) plants as well, but by far we get electricity mainly by burning something.In other words, those 'zero-emissions' cars are likely coal-burning cars. Because the coal is burned somewhere else, it looks clean. It is not true. It's as if the California Greens are covering their eyes—“If I can't see it, it's nothappening.” Gasoline is an incredibly efficient way to power a vehicle; a gallon of gas has a lot of energy in it. But when you take that gas(or another fuel)and first use it to make electricity, you waste a nice part of that energy, mostly in the form of wasted heat--at the generator, through the transmission lines, etc.A gallon of gas may drive your car 25 miles. But the electricity you get from that gallon of gas won't get you nearly as far -- so electric cars burn more fuel than gasoline-powered ones. If our electricity came mostly from wind or geothermal, or solar, then an electric car truly would be clean. But for political, technical, and economic reasons, we don't use much of those energy sources.In addition, electric cars' batteries which are poisonous for a long time will eventually end up in a landfill. And finally, when cars are the polluters, the pollution is spread across all the roads. When it's a power plant, though,all the junk is in one place. Nature is very good at cleaning up when things are not too concentrated, but it takes a lot longer when all the garbage is in one spot.1:What’s the main idea of the passages?A.Electric cars aren’t actually clean.B.Electric cars are zero-emissions vehicles.C.Zero-emissions vehicles are popular.D.Gasoline-powered cars are more efficient.2:Which of the following words can replace “be clueless about” in Paragraph 2? D.Show their interest in.3:The electricity we get from a gallon of gas may make our car run _________. 4:In the author’s opinion, compared with cars using gas, electric cars are more__________.A.environmentally-friendly5:It can be inferred from the passage that __________. A.electric cars' batteries are poisonous for a long timeB.now electric cars are used more than their gasoline-powered cousinsC.zero-emissions vehicles should be chosen to protect our environmentD.electric cars are not clean in that we get electricity mainly by burning somethingMulch is a protective cover of material that is spread on top of soil. It is usually made out of organic material, like crop waste. Farmers may keep the remains of maize or other crops on top of the soil. This creates mulch on the soil surface. The plant remains help protect the soil against wind and water damage. Mulching is one of the best things people can do for their plants. It also helps keep the soil from getting dry, and reduces the need for watering plants. It also limits temperature changes in the soil. And it stops unwanted plants, or weeds,from growing. Organic mulch improves the condition of soil. As the mulch breaks down, itprovides material which keeps the soil from getting hard. This improves the growth of roots and increases the movement of water through the soil. It also improves the ability of the soil to hold water. Organic mulch contains nutrients for plants. It also provides a good environment for earthworms and other helpful organisms in the soil.It is easy to find organic mulch materials. Cutup leaves and small pieces of tree bark can be used. Grass cuttings are also a good mulch for plants. Mulch from newspapers works well in controlling weeds.The best time to add mulch depends on your goal. Mulch provides a thick barrier between the soil and the air. This helps to reduce temperature changes in the soil. As a result,mulched soil will be cooler than other soil in the summer. In winter, the mulched soil may not freeze as deeply as other soil. The best time is after the ground has frozen, but before the coldest weather arrives. Spreading mulch beforethe ground has frozen may attract small animals searching for a warm place to spend the winter. Delaying the spreading should prevent this problem. The animals will probably find another place to live.1:The author tells us the following EXCEPT________.A.what mulch is and its benefitsB.the best time to add mulchC.what can be mulched on the soil surfaceD.the bad effects of mulch2:The following can be used as organic materials to make mulch EXCEPT________.3:Which of the following is the benefit of mulch?A.Protecting the soil against wind and water damage.B.Keeping the soil wet and reducing the need for watering plants.C.Reducing temperature changes in the soil and stopping unwanted weeds growing. 4:The main idea of Paragraph 2 is that organic mulch can________. A.improve the condition of soilB.improve the ability of the soil to hold waterC.provide a good environment for earthwormsD.improve the growth of roots and increase the movement of water through the soil5:From the last paragraph, we know ________.A.the best time to add mulch is in spring and summer B.the best time to add mulch is after the coldest weather arrives C.the best time to add mulch depends on weatherD.choosing the best time to add mulch can avoid attracting small animals
