[Q]: Article: I once experienced an unforgettable trip to Gloucester to see some of the world's most beautiful and exciting animals in their own habitat , the North Atlantic Ocean. After a long trip by bus, we got on the ship. After a while, we stopped and everyone on the ship started to shout because we saw a humpback whale . It was wonderful. Sometimes, whales came so close to the ship that you thought you could easily touch them. While we were watching the whales, a guide was giving us some information about them. She told us that we saw only two kinds of whales -- 50-foot humpback whales (singing whales) and 70-foot fin back whales (the second largest whales on earth). She also said we could easily recognize a whale by its tail because every whale has a different kind of tail just like people have different fingerprints. They all have names, and on this trip, we saw "Salt" and "Pepper", two whales named by a biologist and a fisherman. They were swimming together all the time. I took twenty-seven photos, but it was very hard to take them because the whales were quick and stayed on the surface of the ocean just for a short time. It was really something. It was one of the chances that a person hardly ever experiences in life, but I had that chance.

[Q]: Article: 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 . 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 and un-American; they were jailed and beaten. Some were even killed. But in the end, they reaffirmed 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 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 voters being improperly purged from the rolls. Over the years, we have seen provisions 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 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]

[Q]: Article: It is the duty of every man to work. The life of a lazy man is of no use to himself and to others. The man who is too lazy to work is the man who is generally most ready to beg or to steal. Every boy, when he is young, should learn how to do some useful work. But it is not enough that a boy should learn some kind of work. He should put his heart and soul completely into his work, and not waste his spare time. "Work while you work and play while you play" is as good a rule for young people as for the old! There is no better help to diligence than the habit of early rising, and this, just like all other good habits, is most easily formed in youth. There is an English saying, "Lost time never returns". This means that everybody must be diligent and make good use of his time. One must study hard when one is young so that one may make great progress, succeed in life and become useful to one's country. Those who are diligent will never become beggars. Therefore, we can say that diligence is the mother of success.
