We know that many animals do not stay in one place.Birds,fish and other animals move from one place to another at a certain time.They move for different reasons:most of them move to find food more easily,but others move to get away from places that are too crowded.

When cold weather comes,many birds move to warmer places to find food.Some fishes give birth in warm water and move to cold water to feed.The most famous migration(迁移)is probably the migration of fish,which is called “Salmon”.This fish is born in fresh water but it travels many miles to salt water.There it spends its life.When it is old,it returns to its birthplace in fresh water.Then it gives birth and dies there.In northern Europe,there is a kind of mouse.They leave their mountain homes when they become too crowded.They move down to the low land.Sometimes they move all the way to the seaside,and many of them are killed when they fall into the sea.

Recently,scientists have studied the migration of a kind of lobster(龙虾).Every year,when the season of bad weather arrives,the lobsters get into a long time and start to walk across the floor of the ocean.Nobody knows why they do this,and nobody knows where they go.

So,sometimes we know why humans and animals move from one place to another,but at other times we don’t.Maybe living things just like to travel.

I first visited hutong as part of a tourist group several years ago. We rode on a trishaw(脚踏三轮车) with a guide explaining the history, architecture and lifestyle of the local inhabitants.
Having visited the "must-sees" of Beijing, like the Forbidden City, the Temple of Heaven, the Drum Tower and the Summer Palace, going into the hutong home of some famous ancient families gave the “Beijing experience” a human element.
My curiosity has sharpened over the years from reading about them at every opportunity. During the preparation for the Olympics I was eager to learn that some siheyuan courtyards in hutong were turned into accommodations(食宿) for visitors. I wished to stay in one someday.
Preparing for a recent trip to the capital, I eagerly sought one out. On my limited teacher’s salary, I settled on an affordable option, though I looked longingly at the more upscale courtyard accommodations.
As usual, I ended up having something closer to a true experience. A real family still lives in the courtyard, which is closer to the original. The rooms all opened into the central courtyard. Flowers were blooming, beans and peas were climbing up the bamboo fence, and the cat was napping in the sun. Every day after exploring the city, I'd hurry back to the hutong, take a quick shower and join the cat – snoozing(小睡) in a bamboo-made chair with a book ready nearby.
As the other guests came back we’d greet one another. There was a mother and young daughter from France, a guy from Canada, a mother and teenage daughter from the Netherlands, a teacher from England and several guests from various parts of China.
Coming and going through the narrow alleys(小巷) of the hutong, the residents would smile and give cheery “ni hao” (hello). Laughing children were playing under the watchful eyes of the neighbors. I felt right at home in this friendly neighborhood.

Someday a stranger will read your email without your permission or scan the website you have visited. Or perhaps someone will casually glance through your credit card purchases or cell bills to find out your shopping preferences or calling habits.

? In fact, it is likely that some of these things have already happened to you. Who would watch you without permission? It might be a girlfriend, a marketing company, a boss or a criminal. Whoever it is, they will see you in a way you never intended to be seen-----the 21st century is the equal of being caught naked.

? Psychologists tell us boundaries are healthy and that it is important to reveal yourself to friends, families and lovers at appropriate time and places. But now few boundaries remain. The information you leave everywhere makes it easy for strangers to reconstruct who you are, where you are and what you like. Believe it or not, we live in a world where you simply can’t keep a secret. The key question is: does that matter?

? When you ask Americans about privacy, most say they are concerned about losing it.

? But people say one thing and do another. Only a tiny part of Americans change any behaviors in an effort to preserve their privacy. Few people turn down a discount at tollbooths(收费站) to avoid using the EZ-Pass system that can track automobile movements. And few refuse to offer personal information like Social Security numbers to get supermarket loyalty cards.

? But privacy (隐私) does matter—at least sometimes. It is like health: when you have it, you don’t notice it. Only when it is gone do you wish you had done more to protect it.

With rising temperatures there’s concern for some freshwater fish. If the water gets too warm , then it can change their living activities .For some species in UK the river water needs to stay below 20℃. The problem is as the climate gets warmer so do the streams and rivers .The problem is particularly of concern for the smaller streams and rivers which respond to air temperature changes much more than the deeper and larger rivers .

The method to keep the temperatures of rivers down could be as simple as planting woodlands along the river course .Research has shown that trees cover lowland streams can keep water temperatures 5 ℃ lower than streams running through treeless environments .That 5 ℃  can make the difference between the water temperature being habitable for fish or being too warm for their living .

While it looks like a good method to a problem , there are things that need to be considered . We need to remember that trees are not the favorite habitat of all animals . Some of the habitats need open countryside . Trees can also bring their own problems .A nutrient  poor stream has its own life . Plant trees alongside it and leaves fall in the stream. Falling leaves can change the nutritional makeup of the stream , which will affect the stream and local species of the stream . You have to be careful with this type of management, but his method does offer a real chance to help freshwater living things against climate changes and increasing temperatures.
