Heavy downpours last month in Rhode Island led to widespread flooding, causing millions of dollars in property damage and leaving thousands homeless. The flood waters also poured vast amounts of raw sewage(未经净化的污水) into the rivers and streams that flow into Narragansett Bay.

It sounds like the makings of an environmental nightmare. But in fact it’s just the opposite. To scientists’ delight. The sewage-loaded floodwaters have caused a well-timed growth of phytoplankton. The microscopic creatures that form the foundation of marine(海洋的) food chains. With more food available for fish. Clams and other sea creatures. The bay’s fisheries industry is expected to benefit.

In decades past. Narragansett Bay typically experienced a late winter early spring algal(海藻) bloom that fed creatures up and down the water column. But in recent years, the waters of Narragansen Bay warmed greatly, meriting this seasonal event.

Mark Berman, an oceanographer with the Nationa. Marine Fishertes Service. Said the flood seemed to have sent the bay back in its normal state.

However, local, mutate and federal officials in Rhode Island leave been batting other algal blooms that, by contrast, are causing widespread harm to the Narragansett Bay ecosystem. During summer months, sewage and agricultural runnel flows into the bay. Causing large blooms. But inseam of becoming food for sea creatures, much of the phytoplankton is consumed by bacteria, which grow last in the warmer waters. The rapid bacteria growth leads to hypoxia decrease of oxygen in the water that can cause large fish tools. One such die-off occurred in 2003. when millions of oxygen-starved fish washed up on the belches of Narragansett Bay.

The flood’s positive impact will probably be a one-time event, Mr Berman said. Mcanwhile efforts to curb the harmhl summer honors continue; in 2003. for instance, Providence completed a $359 million sewage tonal under the city designated to reduce the polluted storm overflow into Narragansett Bay.

71.Scientists believe that the row sewage flowing into the bay will           .

A.pollute the island’s environ mean   B.cause lots of property damage

C.increase the fisheries production     D.destroy the food chains in the bay

72.The potential benefit of fisherics industry rclics on the           .

A.warm temperatures of the bay.       B.growth of phytoplankton

C.large summer alga blooms      D.consumption of oxygen by beaters

73.People struggle against the summer blooms because they will          .

A.pollute the local natural environment

B.increase the prcducmon of fishery industry

C.cause large fish kills of the bay indirectly

D.provide too much food ior sea creatures

74.It can be inferred that         .

A.money spent on the summer blooms has been wasted

B.the government is inverting to promote the local fisheries

C.research of accanology should he encouraged

D.she raw sewage impacts are currently con radiator

75.The underlined word “carb” n the hast postage can be defined as “          ”.

下面文章中有5处需要添加小标题。请从以下选项(A,B,C,D,E和F)中选出符合各段意思的小标题。

A.Get adequate iron

B. Keep yourself hydrated.

C. Get enough calories

D. A little exercise goes a long way.

E. Eat a balanced, varied diet

F. Spread your calories throughout the day.

The Energy Diet

How can I lose weight when every time I go on a diet, I'm so exhausted that I can barely make it through the day? So goes the complaint of many men and women who are concerned about being overweight. What many people don't realize is that a healthful weight-loss plan can actually boost your energy. The key is to eat smart. And then combine this healthful diet with some physical activity. Here are six pointers to get you started.

1.____

Consume too few calories and you'll have less energy, and decrease the amount of calories burned. "That's because one of the ways the body protects itself from starvation is to slow down its metabolism," explains Dr. Donald Hensrud, a nutrition professor at the Mayo Clinic, in Rochester, Minn. So how many calories do you need to feel energized while also slimming down? A healthful weight-loss rate is roughly one-and-a-half pounds per week, and the calorie intake to achieve this depends on your age, weight, and activity level.

2.____

The key to keeping your energy level up when you diet is to eat balanced meals that supply all the nutrients you need. "Vitamins and minerals act like spark plugs," explains Kristine Clark, director of sports nutrition at Pennsylvania State University. "They help release the energy in nutrient-rich food." Try to follow USDA guidelines. They call for 6 to 11 servings per day from the bread, cereal, rice, and pasta group; three to five servings of vegetables; two to four of fruits; two or three of milk or cheese; two or three of meat, fish, or eggs. Avoid fried and creamy dishes, and keep consumption of sweets and desserts to a minimum.

3____

When you go for five to six hours without food, the amount of fuel in your system starts to run low, and you begin to feel tired. Therefore, says Kristine Clark, it's important to eat at regular intervals to keep your energy up. If you exercise, it's important to make sure you have "fuel in the tank" before you head for the gym. Avoid eating a large number of calories at one time, since it's harder to control your total calorie intake, making weight gain more likely.

4____

About 10% of women of childbearing age in the United States are iron deficient. Iron is essential for energy and endurance because it is a vital component of red blood cells, which carry oxygen to working muscles. "Fatigue and listlessness can be directly associated with too little iron," says Frances Berg, a licensed nutritionist in Hettinger, N.D. The best sources of iron are meat, poultry, and some fish. Other sources: fortified cereals, dried beans, dried fruits, and peas.

5____

"I don't have the energy to exercise!" say many dieters. Indeed, a 1998 survey, developed in part by the Center for Sports Medicine at Penn State, found that over 70% of respondents cited "too tired" or "lack of energy" as key reasons to skip exercising. Yet exercise is exactly what these people need. And, lastly, don't try to do too much too soon. Consider breaking your exercise into small units. Instead of trying to do 30 minutes in one chunk, accumulate exercise in short bouts (一场,一回)every day by mowing the lawn, walking to work, or climbing stairs instead of taking an elevator. It won't be long before you reap (收获)the rewards. Imagine carrying a 15-pound sack of groceries around all day. Then think about how much more energy you'd have if you put that sack down.
