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 (屠殺) 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 (導彈防御系統(tǒng)) 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.
69.It can be conclude from the article that        .
A.the relationship between Poland and Russia will be even tenser than before
B.Poland will cancel its plan to mark the anniversary of the Katyn Massacre
C.no Russian leaders have marked the anniversary of the massacre before, though Russia released the truth in 1992.
D.Poland will forgive Russians, for they showed great sympathy after the accident.
70.What would be the best title for the passage?
A.The troubled relationship between Russia and Poland.
B.Poland and Russia united by tragedy.
C.The 70 th anniversary of the Katyn Massacre.
D.A plane crash killing Polish president.

Like many other high school seniors, I eagerly anticipate life after graduation. In less than three months, my belongings will be packed up and shipped to the other side of the country.
I had never imagined, in my wildest dreams, that I would attend college in Ithaca, New York. I had had my heart set on a university in California and of majoring in English.
Nearly all of my friends are staying in state, and I remember thinking to myself, when one friend said she would be going to college in Virginia: Why would someone ever choose to move away from California?
But by a twist of fate, I received a letter from Ithaca College, inviting me to apply for a program in communications. On a while, I decided to apply. What were the chances that I would be selected as a finalist? If I hadn’t applied, I would have always regretted not trying. Yet secretly, I hoped that I wouldn’t be chosen.
But, as things turned out, I was offered one of the scholarships. I also received admission letters from the other colleges I had applied to, all of which were California schools.
As I began to weigh my options, I wrote out a pro/con (利弊) list for each of my schools. I began to realize that my reasons for wanting to go to certain schools in California were based on considerations of comfort. It would be so reassuring to be close to my family and my home.
Then I began to think about the expensive tuitions (學費) and class shortages in the California public school system. These issues were not likely to greatly improve in the next four years. Slowly, I came to the conclusion that Ithaca was the ideal choice for me – culturally, academically and financially.
Fear of the unknown should not be a reason for shying away from opportunities. It might be difficult to adapt to my new situation, but I am confident I have made the right decision.
64. What is the point of the article?
A. To introduce the advantages of studying at Ithaca College.
B. To tell readers what matters when applying to a college.
C. To share the author’s experience of choosing a college.
D. To compare the differences between Ithaca College and California schools.
65. The author decided to go to Ithaca College because ______.
A. she wasn’t accepted by any of her dream schools in California
B. she has a great interest in Ithaca College’s communications program
C. she was offered a scholarship by Ithaca College but not by colleges in California
D. she thinks that teaching and classes are better at Ithaca College than at California schools

A. The author had never thought of going to college in New York.
B. The author is independent and likes adventure.
C. The author believes it will be easy to adapt to college life.

B. Not to let fear put her off something she wants.
C. That nothing we want in life can be achieved without effort.

Getting kids to share their toys is a never-ending battle, and forcing them to do so never seems to help. New research suggests that allowing children to make a choice to sacrifice their own toys in order to share with someone else makes them share more in the future. The new findings are published in Psychological Science.

These experiments were conducted by psychological scientists, Nadia Chernyak and Tamar Kushnir of Cornell University. They found that sharing things with others when they are given a difficult choice leads children to think of themselves as people who like to share. It also makes them more likely to act in a pro-social (親社會的)manner in the future.

Previous research has explained why rewarding children for sharing can backfire. Children come to think of themselves as people who don't like to share since they had to be rewarded for doing so. Because they don't view themselves as "sharers", they are less likely to share in the future.

Chernyak and Kushnir were interested in finding out whether freely chosen sacrifice might have the opposite effect on kids' willingness to share. To test this, the researchers introduced five-year-old children to Doggie, a sad puppet. Some of the children were given a difficult choice: Share a precious sticker(貼紙) with Doggie, or keep it for themselves. Other children were given an easy choice between sharing and putting the sticker away, while children in a third group were required by the researcher to share.

Later on, all the children were introduced to Ellie, another sad puppet. They were given the option of how many stickers to share (up to three). The kids who earlier made the difficult choice to help Doggie shared more stickers with Ellie. The children who were initially faced with an easy choice or who were required to give their sticker to Doggie, on the other hand, shared fewer stickers with Ellie. Therefore, children did not benefit from simply giving something up, but rather from willingly choosing to give something up of value.

“You might imagine that making difficult, costly choices is demanding for young children or even that once children share, they don’t feel the need to do so again,” Chernyak says. “But this wasn't the case: once children made a difficult decision to give up something for someone else, they were more generous, not less, later on.” Chernyak concludes.

1._______ helps children to share more in the future.

A. Rewarding children for sharing                      

B. Forcing children to share

C. Allowing children to share precious things willingly

D. Allowing children to share what they don’t need

2.The underlined word “backfire” means _______.

A. have an opposite effect                                              B. serve as a push

C. cause anger                                                                   D. avoid taking things back

3.Those who were required to share give fewer stickers to Ellie because _______.

A. they regret what they did                                           B. it’s not their own choice        

C. Ellie is not as sad as Doggie                                D. they like to share with a real person

4.We can conclude from the passage that _______.

A. parents will never find a way to get children to share toys

B. a gift should be given to make up for children’s sacrifice

C. children pretend to be generous when they are being observed

D. making difficult choices may influence sharing behavior
