DAnne and Joseph are talking about an interesting question. Why do some people change their names? There can be many reasons. Hanna changed her name to Anne because she thought it would be easier for people to remember. On the other hand, Joseph is thinking about changing his name to an unusual name because he wants to be different.People have a lot of reasons for changing their names. Film stars, singers, sportsmen and some other famous people often change their names because they want names that are not ordinary, or that have special sound. They chose the “new name” for themselves instead of the name their parents gave them when they were born.Some people have another reason for changing their names. They have moved to a new country and want to use a name that is usual there. For example, Li Kaiming changed his name to Ken Lee when he moved to the United States. He uses the name Ken at his job and at school. But with his family and Chinese friends, he uses Li Kaiming. For some people, using different names makes life easier in their new country.In many countries, a woman changes her family name to her husband’s after she gets married. But today, many women are keeping their own family name and not using their husband’s. Sometimes , women use their own name in some situations （情况）and their husband’s in other situations . And some use both their own name and their husband’s.根据短文内容，完成下面表格。different peoplereason to change the nameHannaIt is ____61____ for people to remember.JosephHe wants to have a name that’s ____62_____.famous peopleTheir name may sound _____63_____.Li KaimingUsing different names can make ____64_____ easier.a womanAfter she gets _____65_____, she may change her name.61._________________________________________________________________________

阅读理解 判断给出的语句是否正确，正确的在括号内写(T)不符的在括号内写(F)Do you still get free plastic bags from the supermarkets? Things have changed.China has banned free plastic bags at shops and supermarkets, and people have to pay for using plastic bags.The rule started on June 1. It came because our country tried to make litter less、 Making super—thin plastic bags has also been banned.The Chinese once used about 3,000,000,000 plastic shopping bags a day, and they have caused pollution of the environment. The bags have become a main cause of plastic pollution because they are not easy to break and people throw them away here and there. So the Chinese people are encouraged to bring their own bags for shopping.What kind of shopping bag is the best to bring? Some students in Chongqing have a good idea. They make their own shopping bags. They use old clothes to make cloth bags, and send them to their parents as presents. They also ask their parents and friends to use cloth bags instead of plastic ones. They think it is their duty to protect the environment.( ) 21、 People in China have to pay for using Plastic bags at shops and supermarkets now.( ) 22、 China made this rule because plastic bags were bad for the environment.( ) 23、 The Chinese people are encouraged to bring their own bags for the shopping.( ) 24、 Some students in Chongqing buy cloth bags for their parents.( ) 25、 The main idea of the article is that the bags have become a main cause of plastic pollution.

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

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.Glucose cannot be turned into energy in the bodyA: without diabetes. B: without sugar.C:without insu}in. D:without food.
