参考解析
解析：题干句意：美国眼科学会认为人们在四十岁的时候需要做眼睛基线检查。根据文章首句“Even people with no signs or risk factors for eye disease can suffer vision loss and need to get baseline（基线）eye exams at age 40”可知即使没有患眼疾的征兆或风险，人们都有可能遭受失明，所以在四十岁的时候都需要做眼睛基线检查。
题干句意：Dr. Stephanie Marioneaux认为，眼疾的发展都有发病前兆。根据第三段他说的“Many eye diseases progress without any warning signs”可知，许多眼疾都没有发病前兆。故题干表述错误。
题干句意：视力的变化可以影响你的思想。根据第三段最后一句“Gradual changes in vision can affect your ability to function independently. ”可知视力的逐渐变化会影响你独立工作的能力，并没有将视力变化对思想的影响，故题干表述文中没有提及。
题干句意：根据视力初期筛选结果，眼科医生将建立一个视力定期复查时间表。in-itial screening意为“起始筛选，初期筛选”,follow-up意为“定期复查”。根据文章第四段可知题干表述正确。
题干句意：只有患糖尿病或者高血压的老人需要看眼科医生。根据第五段“People of any age… diabetes（糖尿病）or high blood pressure should consult with their eye doctor to determine how often they should have their eyes checked”可知任何年龄的人，只要有眼疾的症状或有家族遗传史，糖尿病或高血压的人都应该咨询眼科医生做眼部检查的频率。故题干表述错误。
题干句意：白内障和青光眼跟年龄有关。根据第六段“age-related eye diseases such as cataracts（白内障) and glaucoma（青光眼）”可知题干表述正确。
题干句意：大部分美国人更加关注失明的风险甚于关心增变胖或关节痛。根据最后一段“Only 23 percent of Americans are very concerned about losing their vision, while most feel weight gain or joint or back pain are greater worries than vision loss”可知，只有 23％的美国人关注失明的风险，大部分人认为变胖、关节痛或者背痛都比失明严重得多。故题干表述错误。

Many people, including some policemen, believe eye contact is a good test of honesty. If someone can't look at you directly in the eye, then he or she is not playing honestly, they insist. After many experiments, however, a number of experts have found out that good liars can make false eye contact.Eye contact, though not a sure sign of dishonesty, is a clear way to show interest in another person. When a person looks at you and continues to do so, you know his attention is placed on you. When he turns his head away, his mind is probably elsewhere. But there are exceptions. A shy person may have trouble making and keeping eye contact, no matter how interested he is in the other person. And certain nationalities, such as the British and Germans, are much less oriented to eye-to-eye contact than, say, the French and the Arabs.Eye contact should be natural, not forced or overdone.Have short periods of eye contact while you watch other parts of the person's face — especially the mouth. When the person smiles, be sure to smile back. But always make an effort to return your gaze to the person's eyes as she speaks. It is common to look up, down, and all around when speaking to others, and not have eye contact at all times.Too much eye contact, especially if it is forced, can work against you. If you stare at a person, or leer in a suspicious way, the other person may feel uncomfortable and even suspicious about your intent. A fixed stare can seem like aggressive behavior. if it is a challenge as to who will look away first.(1)Many people believe that eye contact is a sign of ___________.A、honestyB、dishonestyC、attentionD、A and C(2)According to the passage, which of the following statements is NOT true?A、Eye contact is a way to show interest in another person.B、When a person looks at you, his attention is placed on you.C、When a person fails to make eye contact, he is definitely not interested in you.D、It is common to look up, down, and all around when speaking to others.(3)While we watch other person's face, we should have short periods of eye contact with, especially, other people's _____________.A、eyesB、noseC、mouthD、ears(4)Which of the following statements is TRUE according to the passage?A、Eye contact is not a good test of honesty.B、Some people may have trouble making and keeping eye contact, no matter how interested he is in the other person.C、If someone can look at you directly in the eye, he or she is playing honestly.D、A number of experts have found out that no one can make false eye contact.(5)This passage mainly discusses ________________.A、how to test one is honest or not by the way of eye contactB、how to make eye contactC、how to avoid too much eye contactD、the function of correct eye contact

Stroke is a leading cause of serious,long-term disability in the United States.2 Stroke is a type of cardiovascular（心血管的）disease. It affects the arteries（动脉）leading to and within the brain.A stroke occurs when a blood vessel that carries oxygenand nutrients（营养物）to the brain is either blocked by a clot（凝块）or bursts. Whenthat happens,part of the brain cannot get the blood(and oxygen)it needs,so it startsto die.3 The brain is an extremely complex organ that controls various body functions.If a strokeoccurs and blood flow can't reach the region that controls a particular body function,thatpart of the body won't work as it should,If the stroke occurs toward the back of the brain,for instance,It's likely to result in some disablity involving vision.The effects of a strokedepend primarily on the location of the obstruction（阻塞）and the extent of brain tissueaffected.4 The American Stroke Association has identified several factors that increase the risk ofstroke.The more risk factors a person has,the greater the chance that he or she will havea stroke.Some of these you can't control,such as increasing age,family health history, race,and prior stroke.But you can change or treat other risk factors to lower your risk.Factors resulting from lifestyle or environment can be modified with a healthcare provider's help.Some of these include:high blood pressure,current smoking,heart disease,andhigh red blood cell count.5 A stroke can happen to anyone at any moment.In fact about 600,000 people havestrokes every year.

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.

共用题干Facts about Stroke1 Every 45 seconds,someone in America has a stroke.Every 3. 1 minutes,someonedies of one.Stroke killed an estimated 167,661 people in 2000 and is the nation's thirdleading cause of death,ranking behind diseases of the heart and all forms of cancer. Stroke is a leading cause of serious,long-term disability in the United States.2 Stroke is a type of cardiovascular（心血管的）disease. It affects the arteries（动脉）leading to and within the brain.A stroke occurs when a blood vessel that carries oxygenand nutrients（营养物）to the brain is either blocked by a clot（凝块）or bursts. Whenthat happens,part of the brain cannot get the blood(and oxygen)it needs,so it startsto die.3 The brain is an extremely complex organ that controls various body functions.If a strokeoccurs and blood flow can't reach the region that controls a particular body function,thatpart of the body won't work as it should,If the stroke occurs toward the back of the brain,for instance,It's likely to result in some disablity involving vision.The effects of a strokedepend primarily on the location of the obstruction（阻塞）and the extent of brain tissueaffected.4 The American Stroke Association has identified several factors that increase the risk ofstroke.The more risk factors a person has,the greater the chance that he or she will havea stroke.Some of these you can't control,such as increasing age,family health history, race,and prior stroke.But you can change or treat other risk factors to lower your risk.Factors resulting from lifestyle or environment can be modified with a healthcare provider's help.Some of these include:high blood pressure,current smoking,heart disease,andhigh red blood cell count.5 A stroke can happen to anyone at any moment.In fact about 600,000 people havestrokes every year. For many years,there was no hope for those suffering a stroke.However,recent breakthroughs have led to new treatments.For the treatments to work,the person must get to a hospital immediately. Some people can reduce their risk of stroke if they_______.A:suffer from a strokeB:will be affectedC:change their lifestylesD:will take placeE:occurs at the back of his/her brainF:controls various body functions

资料：When we see well，we do not think about our eyes very often. It is only when we cannot see perfectly that we realize how important our eyes are.People who are near-sighted can only see things that are very close to their eyes，Everything else seems blurry（=unclear）.Many people who do a lot of work，such as writing，reading and sewing become near-sighted.People who are far-sighted suffer from just the opposite problem. They can see things that are far away，but they have difficulty in reading a book unless they hold it at arm’s length. If they want to do much reading，they must get glasses，too.Other people do not see clearly because their eyes are not exactly the right shape. They have what is called astigmatism. This，too，can be corrected by glasses. Some people’s eyes become cloudy because of cataracts. Long ago these people often became blind. Now，however，it is possible to operate on the cataracts and remove them.Having two good eyes is important for judging distances. Each eye sees things from a slightly different angle. To prove this to yourself，look at an object out of one eye；Then look at the same object out of your other eye. You will find the object’s relation to the background and other things around it has changed. The difference between these two different eye views helps us to judge how far away an object is. People who have only one eye cannot judge distance as people with two eyes.People who suffer from astigmatism have______.A.a difficulty that can be corrected by an operationB.eyes that are not exactly the right shapeC.an eye difficulty that cannot be corrected by glassesD.one eye bigger than the other
