A Pay Rise or Not
"Unless I get a rise, I’ll have a talk with the boss, Henry Manley," George Strong said to himself. George liked his job and he liked the town he lived in, but his wife kept telling him that his pay was not enough to meet the needs of the family. That was why he was thinking of taking a job in Birmingham, a nearby city about 50 miles away. He had been offered a job in a factory there, and the pay was far better.
George lived in Wyeford, a medium-sized town. He really liked the place and didn’t like the idea of moving somewhere else, but if he took the job in Birmingham, he would have to move his family there.
Henry Manley was the manager of a small company manufacturing electric motors. The company was in deep trouble because, among other reasons, the Japanese were selling such things at very low prices.

[单项选择]Most of the animals have little connection with animals of a different kind, unless they hunt them for food. Sometimes, however, two kinds of animals come together in a partnership (伙伴关系) which is good for both of them. You may see some birds sitting on the backs of sheep. This is not because they want a ride, but because they find easy food in the parasites (寄生虫) on sheep. The sheep allow the lairds to do so because they move the cause of discomfort. So although they can live without each other, they do better together.
Sometimes an animal has a plant partner. The relationship develops until the two partners can not live without each other. This is so in the corals (珊瑚) of the sea. In their skins there are tiny plants which act as "dustmen", taking some of the waste products from the corals and giving in return oxygen which the animal needs to breathe. If the plants are killed, or are even prevented from receiving light so that they cannot live normally, the corals will die.A. they can eat its parasites
B. they enjoy travelling with the sheep
C. they depend on the sheep for existence
D. they find the position most comfortable

{{B}}Religious belief and health{{/B}}
Religious beliefs are not always a source of comfort during iii health:
they may actually increase your risk of dying.
A study of nearly
600 older hospital patients, 95 percent of whom were Christian, showed negative
feelings evoked by religious beliefs sometimes predicted mortality.
Key factors that increased the risk of death were feelings of being
"abandoned or punished" by God, "believing the devil caused the illness", or
"feeling abandoned by one’s faith community", the study by researchers at Duke
University Medical Centre and Bowling Green State University showed.
"The study reminds us that religion... can, at times, be a source of
problems in it self, "says lead author Kenneth Pargament.
Several studies have demonstrated a reduced risk of death among those who
attend church regularly, but the new research, published in today’s Archives of
Internal Medicin
A. Those who give up their religious beliefs.
B. Those who blame the devil bravely.
C. Those who could communicate with God.
D. Those who go to church regularly.
