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(發(fā)電機). 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?zé)? 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 not
happening.” 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.

答案小題 1:A 小題 2:C 小題 3:D 小
Mulch 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, it
provides 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 before
the 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 benefits
B.the best time to add mulch
C.what can be mulched on the soil surface
D.the bad effects of mulch
2:The following can be used as organic materials to make mulch EXCEPT________.
A.tree barksB.cutup leaves
C.grass cuttingsD.plastic
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.
D.All of the above.
4:The main idea of Paragraph 2 is that organic mulch can________. A.improve the condition of soil
B.improve the ability of the soil to hold water
C.provide a good environment for earthworms
D.improve the growth of roots and increase the movement of water through the
soil
5: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 weather
D.choosing the best time to add mulch can avoid attracting small animals

少兒英語學(xué)習(xí)誤區(qū)
誤區(qū)一：“錢花到了就行”
對策：正確的選擇是成功的一半，不是錢花到了就行，而是錢花對了才行。家長在選擇學(xué)校時，首先要綜合考慮孩子的具體情況及其學(xué)校的教學(xué)特點。選擇正確了，會使其成為校內(nèi)學(xué)習(xí)的有力補充，相得益彰;反之，耗時低效，不如不上。學(xué)校類型選對了，還要考察辦學(xué)的質(zhì)量和信譽。家長們應(yīng)該慎重地分析比較，選擇社會信譽好，辦學(xué)態(tài)度嚴肅踏實，管理正規(guī)，有一定規(guī)模和歷史的培訓(xùn)學(xué)校。
誤區(qū)二：背單詞是外語學(xué)習(xí)的首要
對策：語言運用能力較重要。
有些家長總是認為校外英語學(xué)習(xí)課堂的老師如果不經(jīng)常默寫單詞，就是不負責(zé)任。在檢查孩子學(xué)習(xí)成果時也以背會了多少單詞為標(biāo)準，甚至對小學(xué)入學(xué)和小孩子也不例外。對于功課和小孩子來說，培養(yǎng)興趣，獲取語感，形成規(guī)范的語音語調(diào)，養(yǎng)成大膽開口講英語的習(xí)慣是較首要的。
對于小孩子和中孩子來說，以聽說為主，正所謂要把耳朵“打通”，讓舌頭“靈活”，培養(yǎng)交際能力的訓(xùn)練更重要。
誤區(qū)三：尋找速成英語班
對策：循序漸進才是真。
培養(yǎng)孩子成材，較忌拔苗助長。事實上，中國缺少以英語為第二語言的國家的那種語言環(huán)境，除了靠日積月累、循序漸進、長期的能力訓(xùn)練外，無任何捷徑可走。當(dāng)然教學(xué)得法，效率會高很多。
誤區(qū)四：家長會英語，可自己教
對策：營造英語學(xué)習(xí)氛圍。
對于大多數(shù)少兒來說，學(xué)英語，應(yīng)該有學(xué)伴，應(yīng)該在課堂上學(xué)。課堂不僅滿足了視覺要求，激發(fā)興趣，而且能培養(yǎng)其觀察能力，拓寬學(xué)習(xí)渠道，培養(yǎng)合作精神。教師所營造的參與，求知和寬松的學(xué)習(xí)環(huán)境給孩子提供了充分的活動和交流的機會。孩子間的互助和競爭也會激勵進取心。
誤區(qū)五：追求通級
對策：學(xué)習(xí)過程是根本。
一些家長總覺得一紙證書在手，真真切切觸摸到了自己的付出得到的回報，心里踏實。其實這種滿足讓孩子在不具備足夠?qū)嵙Φ那闆r下，以低分勉強通級不會有什么積極作用。
當(dāng)然級別證書并非一無是處，經(jīng)過一個階段的學(xué)習(xí)和訓(xùn)練后，積累到一定程度，水到渠成，再拿證書，把它看作這一階段的成果印證，其意義遠大于實用價值。當(dāng)然，設(shè)置科學(xué)的級別診斷是正確教學(xué)方法的導(dǎo)向，不過在選擇時應(yīng)向有關(guān)專業(yè)人士咨詢。
