Besides providing a perfect environment for sea plants and animals to live in, seawater has other values, one of which is that it constantly moves, and its movements produce energy.
The most obvious movements are the waves and the tides. Winds cause the waves, and the gravitational pull of the moon and the sun causes the tides. In places like the Bay of Fundy in Canada, the difference between the high and low tide level can be as much as 40 feet.
France and Britain are now trying to use energy in the tides to produce electricity. Waves can produce electricity and some experiments are taking place to learn more about this. One of the most encouraging areas of research uses the difference between the temperature of seawater at the surface and deep down to produce electricity.
Waves and tides are caused by ________ .
A. the same forces B. different forces C. their own movements D. plants and animals
It can be inferred from the passage that __________ .
A. waves as well as the energy in the tide can produce electricity
B. the highest tide is 40 feet higher than the lowest one at the sea
C. many countries in the world have made the most of energy produced by seawater
D. it is being tried in some developed countries to use energy in the tides to produce electricity
The best title for the passage is ______.
A. Tides and Waves B. How to Produce Electricity C. Seawater D. Another Cheap Energy

The house was quiet at 5 am and Tim’s mother was asleep. Only the sound of the big freezer broke the quiet. He’d dreamt of the cave last night. The purring(輕微顫動(dòng)聲)of the freezer had been the sea.
Tim pulled on a sweater and put some apples into his schoolbag. It was too early for breakfast. He’d eat after he’d been through the cave, sitting on the rocks and staring at the sea.
He wished he had a proper pack. His schoolbag would have to do. What else? Sandwiches—but his mother might wake up if he started pulling out bread for sandwiches. She’d want to know why he had to leave so early. He settled for some biscuits, and left a note stuck to the table:
Gone to Michael’s. Back tonight, Tim.
The sky was high and soft and light outside, though the sun still wasn’t up. Even the highway up the hill was quiet as he made his way down the street. The wind from the sea was fresh and sweet.
The sand hills still breathed heat from yesterday’s sun, though the top of the sand was cool. He ran down to the beach impatiently, but there was no one, just dry sand dancing in the early wind and seabirds marching up and down watching the waves.
The light changed suddenly. The first rays of sunlight stretched (延伸) across the sea. The sun was pushing its way over the edge of the world.
Over the first rocks, along to the point, Tim glanced back. The beach was still empty. The sun sailed higher in the sky.
He could see the cave now, even darker in the morning light. The sand turned silver then dark gold as the water flowed away from it. He had to force himself to go closer. Why was it so much more mysterious now? But it would be silly to go back now after so much trouble. He needn’t go in all the way...
【小題1】What did Tim do at the beginning of the story?
A.He left the house quietly. | B.He had breakfast at home. |

A.had to leave the biscuits on the table |
B.liked biscuits better than sandwiches |
C.had to take biscuits instead of sandwiches |
D.could only find some biscuits in the kitchen |
A.The height of the first rocks. | B.The ups and downs of the waves. |
C.The change in the position of the sun. | D.The vast stretch of the sunlit beach. |
A.The sea looked like a piece of gold. |
B.Seabirds flew away when Tim arrived. |
C.Tim was the only person on the beach. |

For years , many people would not believe that smoke could attack so many parts of the body in so many ways . Study shows , however , that tobacco isn’t one single thing . At least 60% of it is gas—20 different kinds of gas . And one of these is the deadly carbon monoxide (CO) (一氧化碳).
In factories , the amount of this gas in the air is measured , and it must be kept under fixed , safe level . But there is 640 times this safe amount in cigarette smoke .
Oxygen is carried through your body by the red blood cells . But this poison gas , CO, will get to the blood cells before the oxygen can . So , if you smoke your blood carries five to ten times more of this deadly gas than is normal . To make up for this , your body must make more red cells .
The oxygen in your blood passes into your tissues(組織). But here again CO makes trouble . It keeps the oxygen from passing into your tissues as fast as it should . Because of this , cigarette country is always about 8000 feet above sea level . Someone who smokes and lives at sea level gets as little oxygen as a nonsmoker at an altitude(高度)of nearly two miles .This happens to everyone who smokes , no matter how old or how young . Anyone who competes in sports can tell you that those who smoke run out of breath more quickly than those who do not .
1.The gas amount in cigarette smoke is______________.
A.640 times higher than the gas safe levels in factories
B.640 times lower than the gas safe levels in factories
C.640 times as much as that in factories
D.a(chǎn)s dangerous as that in factories
2.If you smoke , ______________ .
A.your blood carries more oxygen than is normal
B.your blood carries much more CO than is normal
C.you can have five to ten times of blood than usual
D.your blood will be poisonous
3.Those who smoke______________.
A.a(chǎn)ll live at sea level
B.don’t live at an altitude of two miles
C.breathe as much oxygen as non-smokers
D.only get the same amount of oxygen at the sea level as non-smokers at an altitude of nearly 2 miles
4.Smokers are______________.
A.easily hurt B.easily excited C.easily tired D.healthy
