In the famous fairy tale, Snow White eats the Queen’s apple and falls victim to a curse; in Shakespeare’s novel, Romeo drinks the poison and dies; some ancient Chinese kings took pills that contained mercury, believing that it would make them immortal, but they died afterwards.

Poison has long been an important part in literature and history, and it seems to always be about evil, danger and death. But how much do you really know about poison?

An exhibition, The Power of Poison, opened last month at the American Museum of Natural History in New York, intended to give the audience a more vivid understanding of poison. The exhibition will continue until Feb. 2016, reported The New York Times.

The museum tour starts in a rainforest setting, where you can see live examples of some of the most poisonous animals: caterpillars, frogs and spiders. Golden poison frogs, for instance, aren’t much bigger than a coin, but their skin is covered in a poison that can cut off the signaling power of your nerves, and a single frog has enough venom to kill 10 grown humans.

The exhibition also features interactive activities. In an iPad-based game, visitors are presented with three puzzling illnesses and asked to identify the poisons based on symptoms. In one case, for example, a pet dog is found sick in a backyard and visitors have to figure out whether it was the toad (蟾蜍), the leaky batteries in the trash or the dirty pond water that did it.

“Poisons can be bad for some things,” Michael Novacek, senior vice president of the museum, told NBC News. “Yet they can also be good for others.”

This is what visitors learn from the last part of the exhibition, which displays how poisons can be used favorably by humans, including for medical treatment.

The blood toxins of vampire bats, for example, can prevent blood from clotting (凝结), which may protect against strokes. A poisonous chemical found in the yew tree is effective against cancer, which is what led to the invention of a cancer-fighting drug called Taxol. One chemical in the venom of Gila monsters can lower the blood sugar of its victims, so it has been used to treat diabetes.

1.By mentioning Snow White and Romeo at the beginning of the story, the author intends to ______.

A. show that poison has long been involved in literature

B. show that poison is always linked with evil and death

C. draw readers’ attention to the topic of the article

D. get readers to think of more examples of the use of poison in stories

2.The underlined word immortal probably means?

A. Live forever. B. Happy. C. Confused D. Famous

3.What is the main purpose of the exhibition The Power of Poison?

A. To give people more knowledge about poison.

B. To teach people how to handle poisonous animals.

C. To inform people about which animals are the most poisonous.

D. To show how poison has been used for medical treatment.

4.Which of the following statements about the exhibition is TRUE according to the article?

A. The exhibition will lead visitors to a real rainforest.

B. Golden poison frogs are the most poisonous animals on display.

C. Those who visit the exhibition can join in some iPad-based interactive games.

D. Visitors can listen to lectures on recent studies of poisonous animals.

The adolescent girl from Tennessee was standing on the stage of a drama summer camp in New York. It was a beautiful day. But the girl didn’t feel beautiful. She was not the leggy, attractive Hollywood type. In fact, she described herself as stupid.

Her name is Reese Witherspoon. Since Reese Witherspoon was six years old, she had admired and respected Dolly Patton, who was a famous country singer. For three years she had gone all out to act, dance and sing, fancying that she could be another dolly Patton.

However, at the end of the camp her coaches told her to forget about singing. They suggested she think about another career. She took their words to heart. After all. why shouldn’t she believe the professionals?

But back at home in Nashville, her mother-a funny, happy, optimistic woman-wouldn’t let her feel depressed. Her father, a physician, encouraged her to achieve in school. So she worked hard at everything and was accepted at Stanford University.

And at 19, she got a part in a low-budget movie called Freeway, which prepared for her role in the movie Pleasantville. But her big break came with Legally Blonde.

“If you can’t sing and you aren’t charming, play to your strengths. If you’re going to make it in this business, better focus on what you’re good at,” she told the interviewer later.

And then came the offer that took her back to her Nashville-playing the wife of a country star Johnny Cash, a singing role. All of a sudden the old fears learned on that summer stage were back. She was so nervous on the stage. But she didn’t give up on the movie or herself. She spent 6 months taking singing lessons again. She learned to play the Autoharp. And the hard work built up her confidence.

Last March, Reese Witherspoon walked up on another stage, the Kodak Theatre in Hollywood, and accepted the Oscar as Best Actress for her heartbreaking, heartwarming singing role as June Carter Cash in Walk the Line.

1.Why was Reese Witherspoon sad at the end of the camp?

A. She was described foolish

B. She was told to give up singing

C .She failed to be famous

D. She had to go back home

2.What was Reese’s parents’ response after her coaches suggested her giving up singing?

A. They agreed with her coaches

B. They only focused on her study

C. They ignored her frustration

D. They encouraged her

3.How did Reese succeed in playing the singing role?

A. By regaining her confidence through hard work

B. By practicing autoharp for over 6 months

C. By making herself leggy and attractive

D. By forgetting that summer stage

4.Which is the best title for the passage?

A. A successful actress B. Reese Witherspoon

C. Never give up D. Fortune is important

The right to vote is one of the most fundamental rights of any democracy. Yet, for too long, too many of our fellow citizens were denied that right simply because of the color of their skin.

Fifty years ago this week, President Lyndon Johnson signed a law to change that. The Voting Rights Act broke down legal barriers that stood between millions of African Americans and their constitutional right to cast ballot(投票). It was, and still is, one of the greatest victories in our country’s struggle for civil rights. But it didn’t happen overnight. Countless men and women marched and organized, sat in and stood up, for our most basic rights. For this, they were called agitators(挑拨者) and un-American; they were jailed and beaten. Some were even killed. But in the end, they reaffirmed (重申)the idea at the very heart of America: that people who love this country can change it.

Our country is a better place because of all those heroes did for us. But as one of those heroes, Congressman John Lewis, reminded us in Selma this past March, “There’s still work to be done.” Fifty years after the Voting Rights Act, there are still too many barriers to vote, and too many people trying to erect(建立) new ones. We’ve seen laws that roll back early voting, force people to jump through hoops to cast a ballot or lead to legitimate (合法的) voters being improperly purged from the rolls. Over the years, we have seen provisions (规定) specifically designed to make it harder for some of our fellow citizens to vote. In a democracy like ours, with a history like ours, that’s a disgrace. That’s why, as we celebrate the 50th Anniversary of the Voting Rights Act, I’m calling on Congress to pass new legislation to make sure every American has equal access to the polls.

It’s why I support the organizers getting folks registered in their communities. And it’s why, no matter what party you support, my message to every American is simple: get out there and vote—not just every four years, but every chance you get, because your elected officials will only heed(留心) your voice if you make your voice heard. The promise that all of us are created equal is written into our founding documents but it’s up to us to make that promise real. Together, let’s do what Americans have always done: Let’s keep marching forward, keep perfecting our union, and keep building a better country for our kids.

[From Obama Weekly Address Aug 8th , 2015]
