1、Geology and Heap
(1)The importance of particular metals in the human diet has been realized within the past few decades, and the idea that geology might be related to health has been recognized for a number of elements such as iodine, zinc and selenium. For example, soils with low iodine contents produce crops, and animals deficient in iodine. A lack of iodine in the human diet leads to some serious diseases.
(2)The ultimate source of metals within the human body is rocks, which weather into soil, gaining or losing some of their chemical constituents. The crops we eat selectively remove from the soil the elements that they require for growth. The water we drink contains trace elements leached from rock and soil. Thus the geology and geochemistry of the environment have effects on the chemistry and health of plants, animals and people.
(3)So far there is no data to suggest that people living on metal-rich soils experience a potential health hazard. The levels of metals within naturally contaminated soils are generally not high enough to cause serious health problems. Living on metal-rich soils does not represent a health risk unless large quantities of soil are digested or metal-rich dust is inhaled. However, small children are particularly exposed to metal-rich topsoil in playgrounds and gardens. They are also the most likely ones to eat potentially dangerous metal-rich soil.
(4)Heavy metals are persistent: they do not break down to other chemicals in the environment. Industrially polluted sites usually undergo intensive clean-up and rehabilitation because heavy metals are a health concern once they enter the food chain. Some trace metals are alleged to cause cancer and are also known to cause poisoning
(5)In contrast, naturally contaminated soils have not been subject too risk assessment studies and rehabilitation measures, despite the fact that they frequently possess metal concentrations well above those of such polluted by humans and above environmental quality criteria.
(6)There is a vital need to understand the potential risks and long-term health effects of living on naturally contaminated soils. Future environmental investigations of naturally polluted soils should concentrate on the potential pathways of metals into the food chain and human body. Geologists should be part of such studies as they can provide the essential background information on rock and soil chemistry as well as the chemical forms of heavy metal pollution.
Geologists are indispensable in the research project on geology and health due to their knowledge on ____ .
【单选题】

A.industrially polluted soils

B.rock and soil chemistry

C.naturally polluted soils

D.the pathways of metals into the food chain

E.the element of iodine

F.the persistence of heavy metals

正确答案:B

1、Operatunity
1. Operatunity is a TV talent show for amateur opera singers, The winners get the chance to sing with the English National Opera. When two housewives, Denise Leigh and Jane Gilchrist won in 2002, their lives changed forever, As they sang Verdi's Rigoletto at the Coliseum (音乐厅) in Rome, they were transformed from working mothers into opera celebrities (名人).
2. "I live in the village I was born in," says Denise, who is blind. "Lots of my neighbours are family, and my life is all about my three children. Jane, who worked as a cleaner and a shop assistant, was in a similar situation." She says. All I had to look forward to was seeing my four children grow up, and I love them, but ... you know there must be more things than life. Winning Operatunity has opened up avenues I never knew existed."
3. "Last year was amazing," Denise continues, "Last month was Paris, before that we were recording at Abbey Road, in London, and recently we had our album launch at the Royal Opera House" "We've been treated like princesses," laughs Jane, "... champagne, chocolates, five - star hotels ..."
4. But it wasn't all so easy. For Denise, the worst part was waiting at the beginning. "After I'd sent in my application form I worried for a month, Then I had to wait ten days after my first audition (试唱). That was awful." Even when they won the competition they were allowed to tell their close family but they weren't allowed to tell anyone else until later. Denise and Jane also found the travelling is difficult. They couldn’t take their children with them while they were away singing, so they had to organise childcare. However, there's been no problem with the physical side of singing: "We didn't have to worry about that as we've had lots of help and wonderful voice training." says Jane. They also had to learn to deal with the media." The kids loved the fact that they could stay up and watch us on TV, but I just couldn't understand why some newspapers were more interested in the fact I divorced at 21, rather than the fact I had just sung at the Coliseum, says Denise.

F.The difficult parts

正确答案:E

答案解析:本题的难度减弱，通读第二段后，回来看选项，找信息提示，可以发现，their lives before，讲的是她们成名前的生活，所以最佳答案是E。

1、Money or Friendship or Both
1. Friends and money don't mix. It's a dangerous combination since a fight over money is one of the fastest ways to end a friendship. But what if a friend asks you to tend him or her some money? If you don't lend your friend the money, you risk losing the friend. If you do lend your friend the money, you risk losing both the friendship and your money.
2. We have to face facts, so here are some situations you might run across with your buddies (伙伴) and some helpful tips (忠告) on how to deal with them. Thinking about why this person needs to borrow in the first place. If he is always living beyond his means, it is his fault, not yours. Any Sensible person would not put himself in a position of debt so often. So simply say "no" to this friend. Even if your friend really needs that money for emergency use and you are willing to help him, before you dive into your pocket, follow this reality check: Do you have the extra money? Are you sure you don't need it? Are you willing to write off that amount if it's not returned? If your answers are negative, do yourself a favor and say "no".
3. Let's assume you can't stand saying "no" to your friend because you don't want him living off cat food. What do you do? Write down these details on a sheet of paper before opening up your wallet:
Amount of the loan.
Date of the loan.
Time of repayment.
Amount of interest (if any).
Lender's and borrower's signature.
This will at least keep the borrower from forgetting the loan so easily, If your friend's loan is past due, it's important that you ask him－and it's actually not rude. The longer you wait, the more you are brood (忧伤), and the more your resentment builds.
4. You can send him a friendly reminder via E - mail. Tell him something like "I'm going over my bank account and I'm just wondering when we'll be able to settle that money thing." E - mail saves you from an uncomfortable face - to - face confrontation. There is almost no chance of turning a bad reaction into an argument. Unlike a public conversation, an E - mail message will always be private.
5. After asking two or three times, you might have to write it off. That's what happens. If he just doesn't have the money or is unwilling, then what kind of friend is that?
Paragraph 3 ____
【单选题】

A.Time to Break off a Friendship

B.Unconditional Assistance to Friends in Need

C.Things to Consider When You Have to Say "No" to Your Friend

D.Things to Think over When You Don't Want Your Friend to Eat Cat Food

E.Strategies for Borrowing Money

F.Advantages of E - mail in Handling Money Issues

正确答案:D

答案解析:本题有一定的难度，主旨句似乎不好确认，但实际上可以把第三段的前三句概括成一句主旨句。第三段主要谈到如果你不能不跟朋友说“不”的话，在借他钱时考虑几件事情。回来看选项，D项Things to Think over When You Don't Want Your Friend to Eat Cat Food，就是对本段的概括，所以答案是D。

1、A Strong Greenhouse Gas
1 Methane is a colorless, odorless gas; it is also a potent greenhouse gas, and once released into the atmospheres, it absorbs beat radiating from Earth's surface. That's why methane is a major contributor to the planet's increasing temperature rise or global warming. Molecule for molecule, methane's heat-trapping power in the atmosphere is 21 times stronger than carbon dioxide, the most abundant greenhouse gas.
2 With 13 billion cows belching almost constantly around the world (100 million in the U. S. alone), it's no surprise that menace released by livestock is one of the chief sources of the gas. Other prime methane sources: petroleum, drilling, coal mining, solid-waste landfills and wetlands.
3 Greenhouse gases like methane and carbon dioxide make up only a small part of Earth's atmosphere, which is 78 percent nitrogen and nearly 21 percent oxygen. And without greenhouse gases to trap the sun's heat and warm the planet, life as we know it couldn't exist. But in the last200 years, human activity that requires burning oil, natural gas, and coal for energy has magnified the greenhouse effect.
4 Atmospheric concentrations of methane have more than doubled in the last two centuries. Blame for this often focuses on big industries and gas-guzzling vehicles. But agriculture plays a major role, too. In the past 40 years alone, the global cattle population has doubled.
5 Cows munch mostly grasses and hay yet they grow big and hefty. Why? Because of the rumen. The rumen holds 160 liters of food and billions of microbes. These microscopic bacteria and protozoa break down cellulose and Fiber into digestible nutrients. A cow couldn't live without its microbes. As the microbes digest cellulose, trey release methane. The process occurs in all animals with a rumen (cows, sheep, and goats, for example), and it makes them very gassy. It's part of their normal digestion process. When they drew their cud, they regurgitate some food to rechew it, and all this gas comes out. The average cow expels 600 liters of methane a day.
That's why we say livestock gas is also a major factor of causing the global warming.
Paragraph 2 ____
【单选题】

A.Life of Macroscopic Bacteria in Livestock's Rumen

B.Ways to Reduce Methane's Heat-trapping Power

C.Agriculture Also Contributes to Increased Concentrations of Methane in the Atmosphere

D.Why Livestock Releases Methane

E.Methane as a Strong Greenhouse Gas

F.Livestock as a Prime Factor of the Greenhouse Effect

正确答案:F

答案解析:本段要表达的中心意思是：livestock排出的甲烷也是温室效应的一个主要源头。
