Why Not Eat Breakfast？

Breakfast is not only the most important meal of the day, it is also the most neglected or skipped. Common reasons for not eating breakfast include lack of time, not feeling hungry, traditional dislike for breakfast, and dieting.

Breakfast simply means "break the fast." Your body spends at least six to twelve hours each night in a fasting state. In the morning your body needs energy to rev up （转动起来） into high gear for the day's work ahead.

If you skip breakfast， you are likely to concentrate less effectively in the late morning， feel irritable， short-tempered（易怒的）， tired， or weak.

When you choose not to eat breakfast, your body stays in slow gear. Also, people

who skip breakfast often binge （无节制的大吃） later in the day at other meals or eat a high-calorie （高卡路里） snack in the morning. Breakfast eaters tend to eat less fat during the day， have more strength and endurance and better concentration and problem-solving ability.

A good breakfast should provide up to 1/3 of your total calorie needs for the day. On the average, we eat 400 less calories for breakfast than for dinner. If breakfast doesn't appeal to you in the morning, try eating a lighter-dinner, earlier in the evening or save half your dinner for breakfast in the morning.

If you still aren't hungry in the morning, start with something small like juice or toast or have a mid-morning snack later when you are hungry.

Not eating breakfast can also cause you to overeat, since a fall in blood sugar often makes you feel very hungry later. To make matters worse, since your body is in a slowed state, it will not be able to burn those extra calories very efficiently. If you feed your body healthy snacks and meals throughout the day, you are less likely to become extremely hungry and stuff yourself as soon as you begin to eat.

Since breakfast is the first and most important meal of the day, choosing the right fuel is important. The best breakfast foods are fruits, juice, lean meat, and grain products such as breads, rice, noodles, and cereals.

36 The word fast" in the phrase "break the fast" in paragraph 2 means

A．"a series of quick actions".

B．"a habit of eating".

C．"a period of not eating".

D．"a strict rule".

Mental Retardation（智力迟钝）

Mental retardation is a condition in which people have lower than normal intelligence and are unable to function at the level expected for their age. People with mental retardation are usually born with it, or it develops early in their lire. They may also have some difficulty with daily living skills such as learning to read and write and caring for themselves.

Doctors and other professionals determine that a person has mental retardation based on their intelligence and how well they can do everyday activities. Intelligence is the ability to learn and understand. Levels of intelligence are measured by special tests called intelligence tests. The score a person gets on one of these tests gives a numerical（数字的）measure of a person's intelligence. This is called an intelligence quotient（智商）or IQ.

An average score on an IQ test is about 90 to 110. A person with mental retardation will usually score below 75 on an IQ test.

The IQ test alone does not determine whether someone is mentally retarded. A person must also have trouble with everyday activities such as getting dressed, eating, washing, or learning basic reading Writing and arithmetic skills.

Mental retardation is not a disease itself. It cannot be cured and it's not contagious（传染的）. This condition can be caused by several things that injure the brain or don’t allow the brain to develop normally. Many times we don't know why a person has mental retardation.

Sometimes it may be caused by genes. Genes are chemical units found in every cell. They carry the instructions telling cells what to do. Sometimes, children receive abnormal genes from their parents.

A defective gene may also develop spontaneously. Neither parent would have passed on the gene, but the gene changes before the baby develops.

Some other problems that can cause mental retardation also happen before a child is born. It is important for the brain to develop properly if a child is to have normal intelligence. "Planning a pregnancy is the most important decision most of us will make in our lifetime. A healthy lifestyle. and good medical care should begin before a woman becomes pregnant and continue throughout the pregnancy," says Jodi Rucquoi, a genetic counselor from Connecticut. If a woman abuses alcohol or drugs or doesn't eat well, there is a risk to the developing baby. Also, a premature birth or problems during childbirth can sometimes harm the baby's developing brain. While premature babies are generally fine. There is a greater chance that they may have mental retardation.

In some cases, a young child can develop mental retardation after being sick with a serious infection or other illness, or after suffering a bad head injury.

36 A child can be taken as mentally retarded If he or she

A was born prematurely.

B has lower than normal intelligence.

C has low intelligence and low daily liing skills.

D has normal intelligence but difficulties In learning.

第二篇Fortunately there are still a few tasty things for us to enjoy in relative security.

第二篇

Fortunately there are still a few tasty things for us to enjoy in relative security. Their numbers, however, are depleted almost daily, it seems, by ruthless proclaimations from the ever-watchful Food and Drug Administration and its allies, our doctors, The latest felon(重罪犯) to face prosecution is the salt of life, sodium chloride(食盐).

Apparently, overuse of salt causes high blood pressure and hypertension, the cause of half the deaths in the United States every year. A few years ago the anti-salt campaigners raised such an uproar that salt was banned from baby food. Currently pressure is being applied to food manufacturers to oblige them to label their products to show sodium content. Because doing so would cost manufacturers money, they argue that they have no idea how much salt remains on such things as potato chips and how much sticks to the bag. Furthermore, salt isn't the only harmful ingredient in food. If the manufacturer has to provide sodium content, why not require him to list every ingredient and specify which are harmful to our health？ Cigarettes have a warning printed on them. Shouldn't the same type of warning appear on canned foods that are notoriously over- salted？

There are endless ifs and buts in the controversy, but the most telling of these is the questionable proof of salt's effect upon the blood pressure. True, people who cut their salt intake lowered their blood pressure, but where is the scientific proof that something other than salt didn't do the trick？ The most common means of providing dubious proof that salt causes hypertension is to compare societies that use little salt with those that use mountains of salt in their daily diets. Which group has the higher rate of hypertension？ Whose blood pressure is lower？ What happens when salt is introduced into a group where salt is a novelty？ Does the blood pressure rise significantly？ Studies of the Japanese indicate that as the world's greatest salters, they suffer the most from hypertension. On the other hand, the simple, salt-free cooking of several tribes in the Solomon Islands has kept older tribesmen and women from developing hypertension and high blood pressure, ailments traditionally killing their peers in America. No account is taken of the effects of inflation, recession, pollution, crime, and sundry (多种多样的) other ills to which Americans, unlike people on primitive islands, are exposed.

To salt or not to salt？ That is the question. Now that the question has arisen, it must not be treated with levity(轻率) but, rather, with searching scientific investigation so that those of us who are preoccupied with both savory(薄荷) food and longevity may decide which of the two is worth its salt.

The attitude of the author of this passage toward the salt controversy is that______。

A. we must stop eating salt immediately

B. she is not convinced that salt is harmful

C. the Food and Drug Administration works well with doctors

D. soon there won't be anything tasty left to eat
