Four strange scholarships that actually exist

The scholarship for the tall

If you find yourself having to lower your head to enter doorways then you might get this unusual scholarship. If you are a boy 6'2" or taller, or a girl 5'10" or taller, then you can be in the running for the Tall Clubs International Scholarship. All you have to do is write a simple message titled “What being tall means to me,” and you could get $1,000.

The scholarship for the fat

This unusual scholarship is made available to New England high school seniors who are single, overweight, and have maintain(保持) at least a 2.5 GPA. Every year two people are awarded the $500 prize. It’s kind of like saying being fat and unpopular is not that bad after all.

The scholarship for the short

If you aren’t tall enough for the tall scholarship, maybe you are short enough for the short one. The Billy Party Foundation offers this unusual scholarship to students who are short. One needs to be shorter then 4'10" and have a medical certificate as proof of dwarfism.

The scholarship for golf caddies(球童)

Did you know that you could get a free ride to college for being a golf caddie? Okay, it’s a little harder than that, but each year the Evans Scholars Foundation covers tuition(学费) and housing for hundreds of student caddies from all over the country. Most Evans scholars go to one of the fourteen universities where the Evans Scholar Foundation owns and operates a scholarship house.

              The Diet Zone: A Dangerous Place

      Diet Coke, diet Pepsi, diet pills, no-fat diet, vegetable

diet... We are surrounded by the word" diet" everywhere we look

and listen. We have so easily been attracted by the promise and

potential of diet products that we have stopped thinking about what

diet products are doing to us. We are paying for products that

harm us psychologically and physically (身体上).

       Diet products significantly weaken us psychologically. On one

level, we are not allowing our brains to admit that our weight

problems lie not in actually losing the weight, but in controlling

the consumption of fatty, high-calorie, unhealthy foods. Diet

products allow us to jump over the thinking stage and go straight

for the scale (秤) instead. All we have to do is to swallow or

recognize the word" diet" in food labels.

        On another level, diet products have greater psychological

effects. Every time we have a zero-calorie drink, we are telling

ourselves without our awareness that we don't have to work to get

results. Diet products make people believe that gain comes without

pain, and that life can be without resistance and struggle.

       The danger of diet products lies not only in the psychological

effects they have on us, but also in the physical harm that they

cause. Diet foods can indirectly harm our bodies because

consuming them instead of healthy foods means we are preventing

our bodies from having basic nutrients (营养成分).  Diet foods

and diet pills contain zero calorie only because the diet industry

has created chemicals to produce these wonder products. Diet

  products may not be nutritional, and the chemicals that go into diet

products are potentially dangerous.

       Now that we are aware of the effects that diet products have

on us, it is time to seriously think about buying them. Losing

weight lies in the power of minds, not in the power of chemicals.

Once we realize this, we will be much better able to resist diet

products, and therefore prevent the psychological and physical

harm that comes from using them.

1. From Paragraph 1,we learn that ____   

A. diet products fail to bring out people's potential

2. One psychological effect of diet products is that people tend to ____  .  

A. try out a variety of diet foods

B. hesitate before they enjoy diet foods

C. pay attention to their own eating habits

D. watch their weight rather than their diet

3. In Paragraph 3, " gain comes without pain" probably means____.       

A. losing weight is effortless

B. it costs a lot to lose weight

C. diet products bring no pain

D. diet products are free from calories

4. Diet products indirectly harm people physically because suchproducts____.    

A. are over-consumed

B. lack basic nutrients

C. are short of chemicals

D. provide too much energy
