Dogs are very sociable（合群的） animals．When owners go out and leave their dogs alone，the dogs get worried and upset．Dogs should be trained to be their own while still young instead of when they are older and set in their ways．When owners are not around，they should provide some toys for their dogs to play with．Leaving the radio or television turned on might also provide relaxing background noise．
Howling（嚎叫） is a form of communication．Dogs do it to tell one another where they are．Some dogs howl when they are lonely，while others do it when greeting strangers whom they are seeing for the first time．Some even howl to music and do this because it is fun．
When it comes to training dogs，giving rewards（奖赏） is a far better way than using punishment．Food makes an excellent reward，and if they do not respond（反应） to this，owners should try touching．Dogs like being touched by owners very much．Words of praise work well too，but not as well as food or touch．It helps if owners spend more time with their dogs．

A．When they are born．
B．When they are young．

The first Chinese actor captured （征服） the hearts of many Chinese in the USA． He read a letter by Zhuge Liang（181～ 234）to the emperor of Shuhan during the Three Kingdoms（220～280）period in the new season of Growling Tiger and Roaring Dragon（《虎啸龙吟》）
The letter has been read by so many students． We would never have thought that the text written in old Chinese could be so beautifully read in another language． As a result， foreigners begin to show interest in Rommance of the Three Kingdoms， translated bt C．H． Brewitt﹣Tailor and Robert E． Hegel．
Earlier in November 1979， pupils in England were able to watch a new TV program called Monkey． Most of them were hearing the story for the first time． However， the story of the Monkey King isn't new to Chinese Children in the traditional Chinese book Journey to the West．
As soon as the TV programme came out more than 30years ago， western children became interested in reading this story because the clever Monkey King keeps fighting to help the weak and never gives up．
Chinese scholars（学者） should do a better job of introducing Chinese literature（文学） to the rest of the world． At the same time， we could encourage western schools to try something different．
Reading international literature is an effective way of understand other people in the world． And the more we understand each other， the more beautiful the world will be．

DNA is the whole"map" of the human body.It is something that all humans have，and it tells the body what to do.DNA is the reason that we look like our parents，because we get some of their DNA to make our own.
People have been trying to understand the human body for a long time.In 1860，Mr Mendel discovered why we look similar to other people in our family.It is because of small things called "genes（基因）"in our body.In 1953，two scientists，Watson and Crick，found out that those small parts are real messages.They are written in the DNA with a special language.
In 1961，another two scientists found the first "word" that they could understand in that language.It shows how DNA tells the cell（细胞） to build its parts.So far，scientists have found all the words in the DNA map，but we do not understand what they all do.By understanding what just one "word" means，we can help to save people from several illnesses.So the more we understand ，the more doctors will be able to do.
Most people hope that this will help to make better medicine to help sick people，Other people worry that when we learn more "words" and find out more information，we will use it in the wrong way，just to make people more attractive（有吸引力的）or stop sick people getting jobs.

The world uses about a thousand million （百万） tons of water a day． Water is a human right and everyone should have their share． Yet more than 700 million people around the world have trouble getting clean， safe water．
Treating wastewater is a good way to provide fresh water for us． And it also helps the environment by keeping waste out of rivers and oceans． 80% of wastewater around the world is not treated at all， and it is running into oceans．
But now we have got the technology to treat and reuse the wastewater．
While 75% of our planet is covered with water， only about 2% is fresh water﹣that comes from rivers， lakes， ice and snow． The rest， 98% of the water， is in seas and oceans． It is too salty to drink． Then desalinationbusinesses come in． More than 19.000 factories have been built around the world， mostly in coastal countries． They process（加工） more than 92 million tons of water every day． But the technology they use requires a lot of energy．
