请阅读短文，完成此题。What should you think about in trying to find your career? You are probably better at some school subjects than others. These may show strengths that you can use in your work. A boy who is good at mathematics can use that in an engineering career. A girl who spells well and likes English may be good at office work. So it is important to know the subjects you do well in at school. On the other hand, you may not have any specially strong or weak subjects but your records show a general satisfactory standard. Although not all subjects can be used directly in a job, they may have indirect value. Knowledge of history is not required for most jobs but if history is one of your good subjects you will have learned to remember facts and details. This is an ability that can be useful in many jobs.Your school may have taught you skills, such as typing or technical drawing, which you can use in your work. You may be good at metal work or cookery and look for a job where you can improve these skills.If you have had a part-time job on Saturdays or in the summer, think what you gained from it. If nothing else, you may have learned how to get to work on time, to follow instructions and to get on with older workers. You may have learned to give correct change in a shop, for example. Just as important, you may become interested in a particular industry or career you see from the inside in apart-time job. Facing your weak points is also part of knowing yourself. You may be all thumbs when you handle tools; perhaps you are a poor speller or cannot add up a column of figures. It is bitter to face any weaknesses than to pretend they do not exist. Your school record, for instance, may not be too good, yet it is an important part of your background. You should not be apologetic about it but instead recognize that you will have a chance of a fresh start at work.According to the passage, if a student's school record is not good, he__________.查看材料A．will be a complete failure in his future workB．will not be able to find a suitable jobC．will regret not having worked harder at schoolD．may do well in his future work

共用题干第二篇 Diabetes（糖尿病）and Eye DamageOver 2 million Canadians have diabetes.It is the leading cause of blindness in North Americans under 65 years of age.Diabetes is a condition where the body either cannot produce enough insulin（胰岛素）or cannot respond properly to insulin. Insulin is important because it moves glucose（葡萄糖）,a simple sugar, into the body's cells from the blood. The food people eat provides the body with glucose,which is used by the cells as a source of energy.If insulin isn't available or doesn't work correctly to move glucose from the blood into the cells,glucose will stay in the blood,leading to high blood sugar levels.High blood sugar levels damage the blood vessels,including the tiny blood vessels in the eye．This leads to an eye disease known as diabetic retinopathy（糖尿病型视网膜病）. The retina（视网膜）is an area at the back of the eye that changes light into nerve signals. With diabetic retinopathy,some blood vessels in the retina are lost,and some of the other blood vessels begin to"leak"blood.This causes the retina to swell,and gradually cuts off its supply of oxygen and nutrients（滋养物）.Eventually , the retina starts to grow new blood vessels to replace the damaged ones.Unfortunately,these new vessels are not as strong as the old ones.They are more likely to break,causing bleeding in the eye.At first,people with diabetic retinopathy will not notice any symptoms.As the disease gets worse , they may notice blurred（模糊的）vision, black spots or flashing lights. As time goes on,it can progress to blindness.Everyone with diabetes is at risk for diabetic retinopathy,and the risk increases the longer you've had diabetes.Fortunately,you can reduce your risk.If you do not have diabetes,but think you may be at risk for this condition,visit your doctor to be screened for diabetes.If you do have diabetes:Have frequent eye check-ups.Make sure that you monitor your blood sugar frequently and use your medications as recommended by your doctor. There is evidence to show that keeping your blood sugar under tight control can slow down eye damage.If you have high blood pressure,follow your recommended diet and medications to keep it under control.If you are not sure whether you have high blood pressure,or whether your blood pressure is under control,discuss this with your doctor.With diabetic retinopathy,the damaged blood vessels in the retinaA:are stronger than what they used to be.B: cannot be properly replaced.C:are more likely to break than the new ones.D: may return to normal again.
