录音中指出vegetarian diet（素餐）是the most energy-efficient（最节能的），而“…fish almost was on par with red meat as the least efficient…”（鱼肉和红肉一样是最不节省能源的），因为进行长途航行去捉掠食性鱼需要大量化石燃料。on par with与…不分上下，与…同等水平。
【录音原文】
To find out which types of foods require the most fossil fuels and, as a result, release the most C02, they considered five different diets. Each equaled 3,774 calories a day, and ranged from the average American diet to red meat, fish, poultry, and vegetarian diets. It came as no surprise to the researchers that the vegetarian diet ranked number one as the most energy-efficient, followed by poultry and the average American diet. It did come as a surprise, however, that fish almost was on par with red meat as the least efficient—a large amount of fossil fuel is necessary for long-distance voyages to catch large predatory fishes such as tuna and swordfish. Moreover, salmon farming is not energy efficient.

Passage FourHow can we get rid of garbage?Do we have enough energy sources to meet our future energy needs?These are two important questions that many people are asking today．Some people think that man might be able to solve both problems at the same time,They suggest using garbage as an energy source,and at the same time it can save the land to hold garbage．For a long time,people buried garbage or dumped it on empty land．Now,empty land is scarce．But more and more garbage is produced each year．However,garbage can be a good fuel to use．The things in garbage do not look like coal,petroleum,or natural gas;but they are chemically similar to these fossil fuels．As we use up our fossil-fuel supplies,we might be able to use garbage as an energy source．Burning garbage is not a new idea．Some cities in Europe and the United States have been burning garbage for years．The heat that is produced by burning garbage is used to boil water．The steam that is produced is used to make electricity or to heat nearby,buildings．In Paris,France,some power plants burn almost 2 million metric tons of the cities garbage each year．The amount of energy produced is about the same as would be produced by burning almost a half million barrels of oil．Our fossil fuel supplies are limited．Burning garbage might be one kind of energy source that we can use to help meet our energy needs．This method could also reduce the amount if garbage piling up on the earth．The best title for the passage may be______A.Garbage and the EarthB.Fossil Fuel and GarbageC.Land and GarbageD.Garbage?Energy Source
资料：There's a good chance that spicy crunchy tuna roll you ordered for lunch doesn't actually contain any tuna at all.That's because 74% of fish sold at sushi venues in the US is mislabeled and often completely different than what's on the menu, according to a 2013 survey from the ocean conservation group Oceana.But new technology could help make the seafood business a bit more transparent. Google is teaming up with Oceana and the aerial and satellite imaging nonprofit SkyTruth to launch Global Fishing Watch this fall, the New York Times reports. The initiative will track and analyze fishing boat practices using satellite technology and, ideally, help ensure that fewer fake or mislabeled fish are swapped in along the way.Seafood providers are also investing in technology to reduce fraud. Boston seafood distributor Red's Best, for example, has increased transparency by selling fish with labels that buyers can scan with their smartphones to access a web page that provides details about the individual fish, including where the fish came from, the New York Times reports.Even if a restaurant serves some real, correctly labeled fish, 95% of the 118 sushi restaurants surveyed by Oceana in cities including New York, Chicago, and Los Angeles had at least one faked sushi item on the menu.Currently, the biggest culprits for fake sushi are snapper （92% misleadingly labeled） and tuna （71%）. White tuna is often swapped for escolar, which is sometimes called the "Ex-Lax Fish, " according to Inside Edition, because it can cause intestinal problems.Roughly 75% of fish labeled snapper isn't even from the snapper family. Because of the predominance of fraud in the supply chain, New York sushi restaurant Sushi Nakazawa refuses to serve red snapper because the risk of fake fish is too high.According to the passage, we can infer that______.A.Sushi restaurants verified by Oceana provide no fake fish.B.it would be better not to eat sushi in America.C.the new technology can help deal with the fake sushi to some extentD.fake or mislabeled fish will no longer exist in the sushi market.
Fossil fuels are and will be still ______ for at least the next two-three decades at relatively low costs.A.productiveB.convenientC.renewableD.available
