考题 No Sweet Talk About SugarSugar's proponents call it quick energy, opponents say it's empty calories (卡路里) 。 But to the average person, who consumes a quarter of a pound of it each day, sugar is mostly an irresistibly good taste.In fact, people seem to have an innate "sweet tooth."Human societies have long equated sweetness with goodness - sweet mystery of life, sweet smell of success, sweetheart - and that enhances (增强;提高) the attraction.But in recent years, sugar has also been singled out as a potential enemy of the healthy life.Cited for such evils as distracting youngsters from more nutritious (营养的) foodstuffs, enhancing obesity (肥胖), ruining teeth and causing diabetes(糖尿病), it has become the most maligned (恶毒的) of the main components of our diet.Sugar, like starch, is a carbohydrate (碳水化合物).Its many types include sucrose (table sugar refined from sugarcane or beets), lactose (milk sugar), fructose (fruit sugar), glucose (blood sugar), dextrose (右旋糖), maltose(麦芽糖) and galactose (半乳糖).Seventy percent of the sugar in the labels on all the packaged products in your pantry (食品室) and see how many list sugar (or corn syrup) as a main ingredient (成分) 。Early this century, the average North American consumed about 76 pounds of refined sugar a year, but starches formed two thirds of his dietary carbohydrates.Today, per-capita refined sugar consumption hovers around 95 pounds, and all types of sugar represent more than half the carbohydrate calories.But in relying on sucrose-sweetened processed foods as a main carbohydrate source, we may miss the essential nutrients - fiber, vitamins and minerals - found in other carbohydrate foods like fruits, vegetables and breads.The body has no physiological need for sucrose that cannot be satisfied by other, more nutritious foods.The body can convert starches to sugar, or use the sugar in fruits and vegetables for energy.In fact, nutrition experts say that even the purported (传说的) need for sugar as quick energy is a myth except in a few rare situations, such as a diabetic in insulin shock.During exercise, the body calls upon its reserve of glycogen (肝糖) (and, if that runs low, fatty acids from the breakdown of triglycerides) to supply the muscles with needed energy.If you eat sugar before exercising, your body simply stores it.As for sugar's reputed adverse (不利的) health effects, the following can be said on the basis of available evidence:Obesity, Sugar supplies four calories per gram - about the same as protein and less half that of fat.Excess caloric intake, not sugar, causes obesity.But since calories can be highly concentrated in sugar-sweetened foods, you may eat many more calories than you need of such foods before you feel full or even realize how much you consumed.Tooth decay.Sugar definitely promotes the development of dental caries.Bacteria in the mouth digest (消化) the sugar on tooth surfaces, and produce acid which eats away the enamel (珐琅).It is the time sugar remains on the teeth, rather than the amount eaten, that makes the difference.To reduce the risk of decay, dentists recommend rinsing your mouth or brushing you teeth after consuming anything sweet, and avoiding sweets between meals.Diabetes.In diabetes, the pancreas (胰腺) fails to produce enough insulin to clear the blood of excess glucose.Thus, diabetics must curb their intake of sweets lest their blood-sugar levels rise dangerously high.But the important factor in diabetes is controlling body weight.Heart Disease.The theory that sugar is an important factor in heart disease does not have wide support among experts, who say that fats and cholesterol (胆固醇) are the more likely culprits (罪魁祸首).Some people have a tendency to develop high blood levels of fatty substances called triglycerides, which may promote atherosclerosis (动脉硬化).They are often advised to reduce their sugar intake, but losing weight is more important.Diets free of sucrose can lower abnormally high triglyceride levels, but they have been found to have little or no effect on triglyceride levels that are acceptable in the first place.1、What does the word "innate" mean?()A、born withB、implantedC、badD、healthy2、Which of the following statements is NOT true?()A、There are many types of sugar such as sucrose, lactose, fructose, etc.B、Sugar can cause many health problems such as obesity, tooth decay and diabetes.C、Sugar is not nutritious because it doesn't contain fiber, vitamin and mineral.D、Sugar is physiologically needed by the body and can not be substituted by other substance.3、"Curb their intake of sweets" can also be referred to as()their intake of sweets.A、increaseB、decreaseC、limitD、take4、Based on the ideas presented in the passage we can conclude that ().A、there is not available evidence to show sugar's bad effectsB、if you eat a lot of sweet food, you may suffer from obesity, because such food contains a lot of caloriesC、to limit sugar intake is the most important thing for the atherosclerosis patientD、most experts believe that sugar can cause heart disease5、From the passage, we know().A、sugar eats away the enamel, thus causing tooth decayB、the cause for diabetes is the excessive intake of sugarC、fats and cholesterol have nothing to do with heart diseaseD、high level triglycerides may increase the chances of atherosclerosis

考题共用题干第二篇 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.

考题共用题干第三篇Sugar Accelerate the Process of AgingSugar is widely used in our daily life to make food and drinks sweet,though too much intake of it may lead to diabetes.However,today's study found it also makes people get old faster. Rats that eat high levels of a natural sugar known as fructose seem to age faster than other rats.And the same could be true for people who eat too much sweet junk food,said Israeli researchers.Fructose,a substance found naturally in honey and fruit,is used widely in foods ranging from soft drinks to yogurt. But while its sweet taste is popular,the sugar could cause wrinkles and health problems,the researchers said.Dr. Moshe Werman and Boaz Levi of the Technion-Israel Institute of Technology fed large amounts of fructose to laboratory rats.Writing in the Journal of Nutrition,they said the fructose-fed rats showed changes in the collagen of their skin and bones.Collagen,a fibrous protein found in connective tissue,bone and cartilage,basically holds the body together. The loss of collagen is what causes sagging and deep wrinkles in older people.The process affected,Werman's team said,is known as"cross linking"."Too much crosslinking reduces elasticity and makes the skin stiff and rigid,and these are the conditions that encourage wrinkled skin,"Werman said in a statement. He said the same could be true of people, although this has not been shown."Americans are eating more and more processed foods such as carbonated drinks,baked goods,canned fruits,jams and dairy products that contain fructose," Werman said.Other studies have shown that high fructose intake can affect how the body handles glucose and increases insulin resistance一which can both be important measures of the tendency toward diabetes.The rats Werman worked with were fed much more than the average adult person might eat in a day,which is standard in such experiments.The rats were 12.5 grams of fructose per kg(2.2 pounds)of weight every day for a year. To compare,a person weighing 154 pounds(70kg)who drinks a quart(liter)of cola consumes about 60 grams of fructose,or 0.8 grams per kg of body weight.What do you think is the possible purpose of the author writing the article?A:To alert people choosing the right kind of honey and fruit.B:To suggest people to take appropriate amount of sugar in case of fast aging.C:To show differences in opinion about sugar.D:To help people stay away from diabetes.

考题共用题干 The Tough Grass That Sweetens Our LivesSugar cane was once a wild grass that grew in New Guinea and was used by local people for roofing their houses and fencing their gardens. Gradually a different variety evolved which contained sucrose（蔗糖） and was chewed on for its sweet taste.Over time,sugar cane became a highly valuable commercial plant,grown throughout the world.___________(46)Sugar became a vital ingredient in all kinds of things , from confectionery（糖果点心）to medicine, and,as the demand for sugar grew,the industry became larger and more profitable.________(47)Many crops withered（枯萎）and died,despite growers'attempts to save them,and there were fears that the health of the plant would continue to deteriorate.In the 1960s,scientists working in Barbados looked for ways to make the commercial species stronger and more able to resist disease.They experimented with breeding programmes,mixing genes from the wild species of sugar cane,which tends to be tougher,with genes from the more delicate,commercial type. ________(48)This sugar cane is not yet ready to be sold commercially,but when this happens,it is expected to be incredibly profitable for the industry.__________(49)Brazil,which produces one quarter of the world's sugar,has coordinated an interna-tional project under Professor Paulo Arrudo of the Universidade Estaudual de Campinas in Sao Paulo.Teamsof experts have worked with him to discover more about which parts of the genetic structure of the plant are important for the production of sugar and its overall health.Despite all the research,however,we still do not fully understand how the genes act in sugar cane._________(50)This gene is particularly exciting because it makes the plant resistant to rust,a disease which probably originated in India,but is now capable of infecting sugar cane across the world.Scientists believe they will eventually be able to grow a plant which cannot be destroyed by rust._________（46）A:Eventually,a commercial plant was developed which was 5 percent sweeter than before,but also much stronger and less likely to die from disease.B:Unfortunately,however,the plant started to become weaker and more prone to disease.C: One major gene has been identified by Dr Angelique D, Hont and her team in Montpelier, France.D:The majority of the world's sugar now comes from this particular commercial species.E:Sugar cane is now much more vigorous and the supply of sugar is therefore more guaranteed.F: Since the 1960s,scientists have been analysing the mysteries of the sugar cane'S genetic code.
