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 computable(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 v/hat other effects they may eventually cause.

I suspect that most people have forgotten the serious health scare and complete failure that occurred in 1989 that caused death or health problems for hundreds of people.The product causing the problem was L-tryptophan, an amino acid; Commercially produced L-tryptophan 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 L-tryptophan.

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 or 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 companies 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 companies 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.

68.What's the structure of the passage?

69.The sudden loss of bee hives may be due to ___       .

       A.environmental pollution from human beings

       B.genetically modified products

       C.cross-contamination between modified crops

       D.cross pollination between the fields

70.Which of the following words best describes genetically modified foods?

       A.Risky.           B.Deadly.         C.Harmful.                 D.Healthy.

71.Most companies advocate the genetically modified products in order to _     _.

       A.increase their output                    B.solve health problems

       C.earn more money                         D.protect the ecosystem

A plane crash in Western Russian killed Polish President Lech Kaczynski and the other 96 political and military officials on board on April 10. The accident has led to huge national mourning in Poland. But it may provide an opportunity for reconciliation (和解) between Poland and Russia, countries that have a troubled relationship.
Many from the political elite were lost in the crash. Beside the president, the dead include the army chief of Staff, the head of National Security Bureau, the national bank president, the deputy foreign minister and other members of parliament.
The Polish delegation was heading to Russia to mark the 70 th anniversary of the Katyn Massacre (屠杀) when the accident occurred. In 1940, about 22,000 Polish soldiers, intellectuals, and officials captured after the Soviet Army invaded Poland in 1939, were killed secretly by Soviet police in the forest of Russia’s Katyn.
The Katyn Massacre had been a sensitive topic between the countries. The former Soviet Union always denied responsibility for the massacre. It was not until 1992 that Russian released archived documents about the killing.
Katyn is merely a short chapter in Poland and Russia’s long and troubled history. In the 18 th century, along with Prussia, (then an important part of Germany) and Austria. Russia participated in three carve – ups of Poland. In 1795, after the third carve – up, the country was erased from the map of Europe. It was in 1918 that Poland regained its independence. But in 1939, at the beginning of the World War II, it was invaded by Germany and the Soviet Union under a secret pact. After the war, Poland became a communist country with close ties to the Soviet Union.
In 1989, Poland switched to capitalism and pursued a pro – West position. The most recent tension between the two countries was in 2008. That year, Poland decided to have a US missile shield (导弹防御系统) on its soil, while neighboring Russia threatened to aim missiles at Poland.
But the plane crash has created a chance for reconciliation, with Russia sharing the sadness of Poland. Russia has declared April 12 a day of mourning for the victims. Flags flew at half – mast in Moscow. And earlier on April 7, Russia Prime Minister Vladimir Putin became the first Russian leader to mark the anniversary of the massacre.
“I think it should improve relations between the two countries, as Russians feel our grief,” said Radek Sikorski, Pland’s foreign minister.
66.Put the following events in order of time.
①The Katyn Massacre
②Poland switched to capitalism.
③Russia divided Poland with Austria and Prussia.
④Poland became a communist country.
⑤Poland was invaded by the Soviet Army.
A.③①④⑤② B.③⑤①④②  C.①③⑤④②  D.①⑤②④③
67.After the accident, which of the following did Russia do to share the sadness of Poland?
A.Flags were lowed to half – mast in the capital city of Russia.
B.Russia threatened to aim missiles at Poland.
C.Russia declared the day when the accident happened a day of mourning for the victims.
D.Vladimir Putin marked the anniversary of the massacre.
68.Which of the following is TRUE according to the passage?
A.The Katyn Massacre was the very beginning of Poland and Russia’s trouble relationship.
B.In 1939 about 22,000 Polish soldiers, intellectuals, and officials were killed by Soviet police in the forest of Russia’s Katyn.
C.Altogether 96 political and military officials were killed in the accident.
D.The relationship between Poland and Russia has not always been tense since the three carve – ups of Poland in the 18 th century.

A.the relationship between Poland and Russia will be even tenser than before

C.no Russian leaders have marked the anniversary of the massacre before, though Russia released the truth in 1992.
