Dear editor，
My name is called Zhang Hong．I am a middle school student．When I go to the school every day，I can see a lot of sellers outside around our school walls，sell vegetables，fruits，fish，meat and so on．Some even make dishes in the opening air．
They often shout at the top of their voices in order draw the passers-by's attention．We could hear the noises in the classroom and cannot concentrate on our lessons．Beside，they also make the streets dirt，smelly and crowded．What a shame!How we want to get the situation improved and have our lessons in a quiet place!That's how I write to you for help!

Sonny opened his eyes wide，"Do you mean next time when I'm entering for the 60-metre race I should wish that Billy，Tony and Sandy would all fall asleep halfway？"I was （63）shocked（shock），"But the tortoise didn't wish that the hare would fall asleep!"
"He must have wished that，"Sonny said．"Otherwise how could he be so foolish as to race with the hare？He knew very （64）well （good） the hare ran a hundred times faster than he （65）himself （him） did．"
"He didn't have such （66）a wish，"I insisted．"He won the race by perseverance and by pushing on（67）steadily （steady）．"
Sonny（68）thought （think） for a while．"That's a lie，"he said．"He won it because he was lucky．If the hare hadn't happened（69）to fall （fall） asleep，the tortoise would never have won the race．He could be as steady as you like，but he'd never have won the race．That's for sure．"
I gave up．Today's children are not like（70）what we used to be．

6．Organic food，once considered something that only health fanatics desired，is now a regular feature at most supermarkets．And that has created a bit of a dilemma．On the one hand，you have a conventionally grown apple．On the other，you have one that's organic．Both apples are firm，shiny and red．Both provide vitamins and fiber，and both are free of fat，sodium and cholesterol．
Conventionally grown food generally costs less，but is organic food a better choice？The advantages claimed for such foods over conventionally grown and sold food products are now being debated on a large scale．Supporters of organic foods-a term whose meaning varies greatly-are frequently telling the world that such products are safer and more nutritious than others．
The growing interest of consumers in the safety and nutritional quality of daily foods is a welcome development．However，much of this interest has been aroused by sweeping claims that the conventional food supply is unsafe or inadequate in meeting nutritional needs．
Almost daily，the public is surrounded by claims for"no-aging"diets，new vitamins and other wonder foods．There are numerous unsubstantiated reports that natural vitamins are superior to man-made ones，that fertilized eggs are nutritionally superior to unfertilized eggs，that untreated grains are better than those treated with insect spray and the like．
Although most of these claims are not supported by scientific evidence，large amounts of written material about the benefits of organic foods makes it difficult for people to separate fact from fiction．As a result，claims that eating a diet consisting of organically grown foods prevents or cures disease or provides other benefits to health have become widely advertised and form the basis for people's opinion．
One thing that most organically grown food products seem to have in common is that they cost more than conventionally grown foods．But in many cases consumers are misled if they believe organic foods can maintain health and provide better nutritional quality than conventionally grown foods．So there is real cause for concern if consumers，particularly those with limited incomes，distrust the conventional food supply and buy only expensive organic foods instead．

41．According to Paragraph 2，which of the following statements about organic food is true？A
A．It has no agreed definition．
B．It is popular among producers．
C．It is accepted by most nutritionists．
D．It hasn't been used until recent years．
42．In Paragraph 4，treated grains are examples ofB．
A．organic food B．conventionally grown food
C．expensive food D．healthier food
43．It can be inferred from the passage thatC．
A．organic foods are actually less nutritious than conventionally grown foods
B．people cannot separate fact from fiction because of the TV advertisements
C．organic foods cost more but are not necessarily better than conventionally grown foods
D．most doctors believe that organic foods prevent disease or provide other benefits to health
44．According to the passage，many consumers are attracted by organic foods because theyB．
A．have carefully researched the products
B．value food safety and nutrition
C．expect to save some money
D．want to try something new
45．What is the author's attitude toward the claims of organic foods？D
A．Enthusiastic． B．Supportive． C．Uninterested． D．Doubtful．
