I think that genetically modified foods should be banned.Here’s why.

We have no idea of the real impact they have on our environment.While there’s currently no hard proof that environmental damage is being done by genetically modified foods，there are a few worrying and suspect events that may actually be tied to these products.Most important is the sudden loss of huge numbers of bee hives.Bees are necessary to the pollination process for soybeans and many other food crops.It’s entirely possible that“the law of unintended consequences”has caused the loss of these extremely important insects.

There’s also no real way to prevent cross contamination(交叉污染)between modified crops and natural crops.When neighboring fields are planted with different varieties

of patible(可共存的)plants，there is a virtual guarantee of some cross pollination between the fields.

We have no idea of the real impact they have on human beings.There is already documented evidence that genetically modified foods may be the cause of higher allergy(过敏)rates in children.It’s impossible to guess what other effects they may eventually cause.

I suspect that most people have forgotten the serious health scare and plete failure that occurred in 19 that caused death or health problems for hundreds of people.The product causing the problem was L­tryptophan，an amino acid.mercially produced L­tryptophan is developed through a bacterial fermentation process.One maker of the supplement developed a genetically modified strain of bacteria which was capable of producing higher quantities of L­tryptophan.Unfortunately，the process“broke”somewhere along the line with the genetically altered bacteria creating an altered form of the chemical which had devastating effects on people who consumed it.Since there is no way to predict these kinds of changes，it’s both foolish and dangerous to introduce genetically modified products into the food chain.

Finally，there’s no need for genetically modified foods.Most panies that produce these products will send out statistics about higher output per acre or plants that are more tolerant to negative conditions.But the truth is that the claims，while at least partially true，are mostly rhetoric.These panies are really just looking for a way to increase their bottom line profits.They may not actually intend to damage the ecosystem or create new health problems for people.But in my opinion it’s not nice to fool Mother Nature.She may offer up a variety of severe surprises in response.

Failure，they say，is the best teacher.We learn and gain more confidence through trial and error.At one time or another we will encounter failure.You don’t have to accept your failure if what you really want to achieve is success.

For every achievement，there have been one or more failures.But those who we call successful are those who refuse to accept failure and believe success is the other side of failure.The incandescent light(白炽灯)was invented after 1,000 failures.Assuming he had stopped after he tried 100 times without the desired result，what would have been the result of such effort?

Any time you see products and new inventions，think in term of failures that are not accepted.Moreover，everything in a microform today is a result of failure that is not accepted.Any time your effort is not bringing a desired result，you don’t have to call it a failure.Call it a challenge.What is the difference between the two？One is negative，and the other is positive；one motivates，and the other demotivates.

What you need is positive thinking and motivation to attain success.Failure is an end thing；challenge is an open thing.Failure means there is no way out，no alternative，

but challenge is a question mark asking another way out of the situation，an alternative solution to the problem，the job at hand.Keep dreaming and moving；that is the solution to success.A wise man once said if you cannot fly，run.If you cannot run，walk.If you cannot walk，crawl；just keep on moving.

If you fall down，you have to get up and start moving.If not，other people will step on you to the way to their success.What you call failure and abandon is what someone will continue with just a little additional effort to reach success.

语篇解读：失败是最好的老师。不少人经过无数次失败后才获得成功。我们应该把失败看成挑战，树立目标，坚持不懈，努力去实现成功。

5．Failure is the best teacher because______. A．what people have learned from failure is the best B．people will know what failure is like after failure C．people can learn a lot by trying various solutions D．numerous failures are sure to lead to success

解析：推理判断题。根据第四段Failure is an end thing；challenge is an open thing可推断，答案为D。
