Some scientists say that animals in the ocean are increasingly threatened（威胁）by noise pollution caused by human beings． The noise that influences sea animals comes from a number of human activities． It is caused mainly by industrial underwater explosions（爆炸）， ocean drilling， and ship engines． Such noises are added to natural sounds． These sounds include the breaking of ice fields， underwater earthquakes， and sounds made by animals themselves．
Decibels（分贝） measured（测量） in water are different from those measured on land． A noise of one hundred and twenty decibels on land causes pain to human ears． In water， a decibel level of one hundred and ninety﹣ five would have the same effect（效果）．
Some scientists have planned to set a noise limit（限度）of one hundred and twenty decibels in oceans． They have found that noises at that level can frighten and confuse whales（鲸鱼）．
A team of American and Canadian scientists discovered that louder noises can seriously hurt some animals． The research team found that powerful underwater explosions were causing whales in the area to lose their hearing． This seriously affected the whale's ability to exchange information and find their way． Some of the whales even died． The explosions had caused their ears to bleed．
Many researchers whose work depends on ocean sounds disagree to a limit of one hundred and twenty decibels． They say such a limit would mean an end to important industrial and scientific research． Scientists do not know how much and what kinds of noises are harmful to ocean animals． However， many scientists think that noise is a greater danger than they believed．It's time for them to take action to help ocean animals．
（1）Which of the following is not caused by human beings？
A． The noise of industrial underwater explosions．
B． The noise of ocean drilling．
C． The sound of underwater earthquakes．
D． The noise of ship engines．

What is one thing that would help parents understand their kids better？ More than 8，000 US kids answered this question in an online poll （投票） by KidsHealth．org．
Many US kids ﹣ two out of three ﹣ said they get along with their parents． But that doesn't mean they never disagree． In fact， most kids reported arguing with their parents，at least sometimes．And two out of five kids said arguments sometimes even include shouting at each other．
"It's certainly normal to disagree and argue，" says Darcy Lyness， an American expert． "But it's also important to learn how to do so respectfully （尊重地）． Be patient． Don't use a raised， angry voice．"
And not surprisingly， three out of four kids said they had lied to their parents sometimes． Many said they lie so they would not get in trouble or disappoint their parents． According to Lyness，lying isn't just wrong． It can actually have bad results． Telling the truth builds trust．
Telling the truth， says Lyness， shows maturity （成熟）．But older kids actually lie more often than younger ones． Kids aged 12 to 14 not only said they lie more，but they also reported having less fun， feeling less close and not getting along as well with their parents．
According to Lyness， those feelings are common．As kids become more independent （独立），they have more areas of disagreement with their parents．But it doesn't have to be that way．"Kids and parents get along differently at each stage of the journey，" she says． "As kids grow and change， it is important for everybody to change．"

Living places
The home of the elephant is in the deep forest． It is the largest of all land animals， and is found both in Asia and Africa． One of the main places in Asia where the elephant lives is the island of Ceylon． The huge forests on the island become the home of thousands of elephants． The trees grow thick and tall． They make many parts almost dark， while bright sunlight is above and around them．
Living habits
The elephant likes the deep part and the coolest places of the forest． There he will stand swinging his ears， to drive away the flies； or he will pull down a branch （树枝） from a tree to fan himself． He likes bathing， and to be near a lake or running water． There he takes in the water with his trunk， and spreads it all over his body．

How people treat them
In Asia the elephant is trained to work． At one time the African elephant also was trained． Soldiers in ancient times often went to fight on the backs of African elephants． But now the elephant that lives in Africa is illegally （非法地） hunted mainly for its valuable ivory． In order to protect them， governments around the world have developed laws to stop this．

What was discovered by accident？ The answer is penicillin（青霉素）． It kills germs． By killing germs， it saves lives． Suppose you are sick． You go to a doctor． She examines you． She says you have a" staph'" infection（葡萄球菌感染）． She gives you some medicine． You take it． The medicine knocks out the staph． Soon you are well． Before penicillin， this would not happen． Staph was almost sure death．
Everyone wanted a medicine． Laboratories worked day and night． They grew the staph in small dishes． Then they tried to kill it． Nothing worked．
The laboratory dishes had covers on them． They kept things from falling into dishes． Molds（霉菌）were a big worry． They are always in the air． You can't see them． They're too small． There are thousands of different molds． Molds can make an experiment （实验）fail． That's why dishes are covered．
Dr． Alexander Fleming was working to kill the staph germ． He worked for years． One day he took a cover off a dish． He looked inside． There was a thick growth of staph germ． There was also some mol
d． Then he saw something strange． Where the mold was， there was no growth of staph． This is what Fleming probably thought． "By accident， I found a mold to kill the dreaded staph．"
This is how penicillin was found． But here's the real miracle（奇迹）． There are thousands of kinds of molds． But only one kind can kill staph． The mold must have fallen into the dish a few days before． The cover was probably off only a few seconds（秒）． In those few seconds the right mold fell into the right dish． Another man might have thrown the dish away． But Fleming was very careful and smart． He understood what the mold did． How lucky the humans were !

Two years ago I bought an exercise bike（健身脚踏车）． But soon I got bored with being at home， so I bought a used bike and started going for short rides． Now I plan day trips in my neighborhood （街区）． When you drive a car， you miss many things． It's surprising how much more you can see when you're biking．

My favourite thing to do at weekends is to go to the beach． The beach is beautiful all through the year． I usually drive there． If the weather is cold， I wear some warm clothes and go for long walks on the beach． When the weather is hot． I enjoy swimming or just lying in the sun．
﹣﹣﹣﹣﹣Barbara
At weekends I like to read books． If the weather is nice， I'll take a good book to the park and stay there reading for hours． I think there's nothing as delightful as reading a good book．
﹣﹣﹣﹣Bill
Weekends are for going hiking（徒步旅行） with my parents． We live near some beautiful mountains． Sometimes we camp out at night． We really enjoy cooking dinner over a campfire and spending a night under the stars!

Artificial intelligence （AI， 人工智能） can help us make phone calls． It can guide us to where we want to go． It can play games． And now， AI can do even more things．
Researchers from Microsoft have created the first machine translation system that can translate news articles from Chinese to English， Business Standard reported．
According to Microsoft's official website， researchers tested the system by asking it to translate hundreds of sentences taken from news stories． Then， language experts compared the results to two translations that were done by humans． The experts said that the system's translations were as good as the human translations．
Machine translation is always challenging． This is partly because different words can be used to express the same meaning． It can be hard to say which word is more "correct"．
Experts used several methods to improve the system's translation abilities． "Much of our research is really learned from by how we humans do things，" lead researcher Liu Tieyan said．
One method is called dual learning （对偶学习）．In this method，the system translates every sentence from Chinese to English，as well as translates the sentences back from English into Chinese．This way，the system can improve itself and learn from its own mistakes． This is similar to what humans do to make sure their translations are exact．
Another method makes use of deliberation networks （推敲网络）．The researchers taught the system to repeat the process of translating the same sentence over and over．Gradually， the system can improve the quality of its translations． This is similar to how people correct their own writing by going through it again and again．
