Tommy White has been rowing across the Pacific Ocean in a rowboat since he left California on July 10 ,2007. He has been heading for Australia with only birds, fish, and sharks ever since.

Crossing the Pacific is only part of his journey. Tommy has decided to go all the way around the world using his own energy. He will row, bike, walk, and climb the world without help from any motor (马达) at all. His plan includes climbing the tallest peak on six of the continents (大陆) along the way.

For the first part of his trip, he bicycled 5,546 miles from Seattle, Washington to Mount Mckinley in Alaska and back, walked 67 miles to base camp, and climbed 20,320 feet to Mckinley's top. Now in the second part of his dangerous trip, he is rowing to Australia.

Why would he try to go around the world this way? He explains that he wants to encourage kids to dream their dreams and get to their own goals. He wants to show kids that there might be hard parts along the way, and sometimes they might not even get to that final goal. But they can have great adventures and learn a lot along the way.

Tommy has already faced some difficulties. For example, wind and waves keep pushing him westward when he wants to go south toward the Solomon Islands. If his luck doesn’t change, he will cheerfully change his plan, and aim to land at Papua New Guinea. One way or another, he's sure he’ll get to his next goal: Australia.

When his trip around the world takes him across land, he enjoys meeting people — especially children. He has already visited many schools and shared his story.

Tommy encourages all kids to set their eyes on a goal and not to give up. He says, "With goals, we will make progress, and we will be farther along than when we started, even if we don't get to some goals. That's called life! ”

1.How has Tommy decided to go all the way around the world?

2.Which part of his trip is he in now?

3.If his luck doesn’t change, where does he aim to land?

4.What does he enjoy on his trip across land?

5.To Tommy, does life mean struggling for (为… 而奋斗)the goals?

When you watch your favorite movies, you might not think about science. Of course, there’s a lot of science behind movies like Interstellar or The Martian but not movies like Frozen or The Avengers, right? Think again.

Animated(动画) movies use a lot of science and math to make things look as real as possible. For example, snow was used in many parts of the movie Frozen, but making the snow look real was a challenge. The snow needed to act differently in different situations, like if it was melting(融化) or blowing in the wind.

Mathematicians(数学家)had to create a computer program to make the snow look more natural. Joseph Teran, a mathematician at the University of California, US, faced this challenge with Frozen, according to the Society for Science and the Public.

He and his team used math equations(等式) to treat snow like many different pieces instead of one large thing, as movies had done in the past. They worked for months to make a computer program do this.

Science is important for superhero movies too. Superheroes are supposed to have special powers that can’t always be explained. But moviemakers still want to make their actions realistic(现实的).

For example, Raychelle Burks, a chemistry professor from the American Chemical Society, told the Daily Mail that some of the science behind The Avengers could be real. Iron Man’s suit is possible because it can be made of a light but strong material. In the movie , Tony Stark also makes new elements by making atoms collide(使原子对撞),much like scientists do in real life.

So next time you see a movie, don’t forget to think about the science behind it.

For ten weeks, in a great house on the island of St Thomas , John C. Lilly tried to teach a six-year-old dolphin to speak English. Margaret Howe, an experiment (试验) helper, would live day and night with Peter, a dolphin. And they would eat, bathe(洗澡), sleep and play together from Sunday to Friday, with only Saturdays off for Margaret. She lived her 1ife in swimming clothes -- with a coat on colder evenings --- and cut her hair short so that she could get on with Peter more easily.

After a few days, Peter was becoming more and more interested in winning her attentions. He threw a ball against her shower towel to get her to play. As time went by, he only wanted to play ball with her and not on his own.

The problem was that, just at the time Peter and Margaret began to get on well just as two best friends, the experiment ended and the lab was closed. After a few weeks, Margaret received the sad news that Peter had killed himse1f by refusing to breathe, and sinking to the bottom of his pool.
