About 97% of the world's water is salty and is found in our oceans and seas. But, as we can't drink seawater, how can it be important?
Every part of our seas and oceans contains an amazing number of animals and fish that live at different ocean depths. Most of the different species of animals and fish depend on simple plants for their food. These simple plants called algae (海藻) drift near the surface of the ocean and use sunlight to turn carbon dioxide and water into food and oxygen. In fact, algae produce over half of the oxygen people breathe. How important seawater is!
Each plant or animal in our seas and oceans is an important link in a food chain. The algae are eaten in large amounts by microscopic animals, which are in turn consumed by larger animals. These food chains are delicately balanced.
The bad news about the food chains in the oceans is that they are under threat because of man. People once thought that the oceans were so big that it didn't matter if we dumped rubbish into them or caught huge quantities of fish and whales for food. But we now know this is not true and fish stocks in the oceans have started to drop.
Thankfully, the world is taking steps to protect the future of our oceans by introducing international agreements to protect marine habitats. Most countries have introduced fishing restrictions to protect fish stocks in the oceans and new techniques are being pioneered to cope with pollution. Finally, the importance of protecting oceans is being made known to more people. This is just the beginning of a long process to protect the oceans for our future. We depend on the oceans for fish which are an important part of the human diet. How important seawater is!
6. Which of the following is the proper order of the food chain?
A. small animals→algae→microscopic animals→large animals→man.
B. algae→microscopic animals→large animals→larger animals→man.
C. small animals→algae→large animals→microscopic animals→man.
D. microscopic animals→algae→large animals→larger animals→man.
7. People used to think that the rubbish thrown into the sea ________.
A. wouldn't harm the fish in the sea
B. would change the balance of the food chain
C. would be broken down in the sea
D. wouldn't do much harm to the sea
8. From the passage, we learn that ________.
A. most fish and sea animals live at the surface of the seas
B. it is very difficult to break the balance of a food chain
C. excessive fishing has caused the decrease in fish stock
D. it won't be long before the problems concerning oceans will be solved
9. Which of the following is NOT a way being used to protect oceans?
A. The use of international agreements.
B. Forbidding fishing to protect fish stocks.
C. The use of new techniques.
D. Raising people's awareness of the need to protect oceans.
10. What would be the BEST title of the passage?
A. The importance of seawater.
B. Life in the oceans.
C. How to protect food chains.
D. How to deal with seawater pollution.

With petroleum reserves (石油储量) decreasing, the search is on to replace gas with a cleaner，greener alternative. Though much eco－talk has centered on biofuels from corn and soybeans, the biofuel that looks more likely to replace petroleum comes from a most unlikely source: algae(藻类)．
Algae, like corn, soybeans, and other crops, grow via photosynthesis(光合作用) and can be processed into fuel oil. However, they yield 30 times more energy than land crops such as soybeans, according to the U．S. Department of Energy. Many algae species also can grow in saltwater and polluted water—while corn and soy require arable land and fresh water that will be in short supply as the world's population balloons.
“If you replaced all the diesel(柴油) in the U．S. with soy biodiesel, it would take half the land mass of the U．S. to grow those soybeans，” says Matt Caspari, chief executive of Aurora Biofuels, a Berkeley, Calif－based private firm that specializes in algae oil technology. On the other hand, the Energy Department says that if algae fuel replaced all the petroleum fuel in the United States, it would require 15,000 square miles, which is a few thousand miles larger than Maryland (12,407 square miles), the 42nd state in land area.
Another bonus: Because algae can be grown just about anywhere in a closed space, they're being tested at several power plants across the nation as a carbon absorber. Smokestack emissions (烟囱排放物) can be pumped directly into the ponds, feeding the algae while keeping greenhouse gases out of the atmosphere.
Although processing technology for algae fuel－also known as “oilgae” in some environmentalist circles—is improving, it's still years away from reaching your local gas pump. “It's just a question of cost, because no large－scale facilities have been built yet，” Caspari says.
1. The underlined word “yield” in Paragraph 2 can be replaced by ________.
A. control B. require
C. produce D. grow
2. Compared with corn and soybeans, algae________.
A. may pollute water and soil
B. can grow in poor conditions
C. provide much less energy
D. need more special care
3. According to Paragraph 3, one of the advantages of algae fuel is that________.
A. it can be used more widely
B. it is more easy to produce
C. it needs much less land
D. it costs much less money
4. What do we learn about algae from Paragraph 4?
A. Algae help protect the environment.
B. People can grow algae anywhere.
C. Fish can get more oxygen from algae.
D. Algae produce less waste.
5. What does the passage mainly talk about?
A. Environmental protection.
B. Biofuels from corn and soybeans.
C. The false hope of biofuels.
D. A promising oil alternative.

With the Tesla Roadster and other plugin (插入式) electric vehicles hitting the road，demand is growing for accessible refueling points to recharge them. Carbon Day Automotive, a Chicagobased company，has now demonstrated a solarpowered recharging point, known as the Solar PlugIn Station，which lets motorists easily charge their cars using electricity that has been produced without any environmental damage.
The Solar PlugIn Station has gone on show in Chicago as part of the city’s bid to host the 2016 Olympic Games. According to Carbon Day Automotive，the Solar PlugIn Station on show in Chicago is part of the vital infrastructure(基础设施) required for electric vehicles in Chicago and was the focus of a recent visit by the International Olympic Committee.
These solarpowered electricity points will be used daily to fuel the city’s electric vehicles with power from the sun. By producing the electricity from pollutionfree solar cell, the CO2 emissions are reduced to zero.
“Solar energy and electric vehicles are a partnership that is one more step to reducing our dependence on foreign oil,” says Richard Lowenthal, CEO of Coulomb Technologies.Coulomb Technologies recently developed the components (部件) required for individual recharging stations，marketed as ChargePoint Networked Charging Stations.Carbon Day Automotive is the Midwest distributor for the ChargePoint stations. The Solar PlugIn Station consists of giant solar panels (电池板) that shade the tiny ChargePoint Networked Charging Station.The solar panel is connected to an underground battery pack，ready for everyday refueling.
“Without these stations it would be like driving around in a traditional car without the availability of gas stations，” says Scott Emalfarb，CEO at Carbon Day.“The day of true plugin electric vehicles will be here sooner than most people realize and the world needs to be ready to accommodate them.”
