Is there intelligent(有智力的) life on other planets For years, scientists said “No.” or “We don't know.” But today this is changing. Seth and Alex are astronomers(天文学家).They believe intelligent life exists(存在) somewhere in the universe. They also think we will soon communicate with these beings(人， 生物).
Why do Seth and Alex think intelligent life exists on other planets The first reason is time. Scientists believe the universe is about 12 billion years old. “This is long enough for other planets to have intelligent life，” say Seth and Alex. The second reason is size. The universe is huge. “We have known that there are at least 100 billion galaxies，” says Seth. “And our galaxy, the Milky Way, has at least 100 billion stars. Some planets going around these stars might be similar to Earth.”
In the past, it was hard to look for signs of intelligent life in the universe. But now, powerful telescopes(高倍望远镜) allow scientists to discover
smaller planets—the size of Mars or Earth—in other solar systems. These planets might have intelligent life.
Have beings from space already visited Earth “Probably not，” says Alex. “It's a long way away. However, intelligent beings may communicate with us in other ways, such as radio signals(信号).In fact, they may be trying to communicate with us now, but we don't have the right tools to receive their messages. However, this is changing. By 2025, we could communicate with other life forms in our universe and we might help each other.”

Everybody, including the police, thinks that Mr.Spenlow is the murderer(凶手) because he is so calm and quiet after discovering his wife's death. But after the police talk to Miss Marple, she finds out the real murderer.
The best part of the story is when Miss Marple explains how she solves the mystery by noticing a tiny pin(别针) on a policeman's uniform. Her explanation is very clear and clever. Miss Marple is my favorite character in the story. I think she is very special because she is just an old lady but she is even smarter than the policemen. I never thought that an old lady could be the main character of a detective story!

Although science, technology and research have made great progress, there are still many unsolved mysteries in our life.
Let's enjoy the following unsolved mysteries.
The Bermuda Triangle (百慕 大三角 区) Located in the western part of the North Atlantic Ocean, the Bermuda Triangle is a loosely defined (宽松定义的) area. There a number of planes and ships are said to have disappeared. Pilots say their instruments can't work there. With explanations from gas bubbles (气泡) to aliens, no one is sure what is behind the strange thing.
The Loch Ness Monster (尼斯湖 水怪) For ages, people have been hearing about the Loch Ness Monster. Over the years photos and videos of actual footprints have been checked and watched over and over again to find out if it could be a sea snake or a dinosaur (恐龙) .Even today, it may still exist and swim under the waters.
