Some scientists say that animals in the ocean are increasingly threatened by noise pollution caused by human beings. The noise that affect sea creatures comes from a number of human activities. It is caused mainly by industrial underwater explosions, 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 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.
Some scientists have proposed setting a noise limit of one hundred and twenty decibels in oceans. They have observed that noises at that level can frighten and confuse whales.
A team of American and Canadian scientists discovered that loud noises can seriously injure some animals. The research team found that powerful underwater explosions were causing whales in the area to lose their hearing. This seriously affected the whales’ ability to exchange information and find their way. Some of the whales even died. The explosions had caused their ears to bleed and become infected.
Many researchers whose work depends on ocean sounds object 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 suspect that noise is a greater danger than they believed. They want to prevent noises from harming creatures in the ocean.According to the passage, which of the following is increasingly dangerous to sea creatures?
| A．The man-made noises. |
| B．The noises made by themselves. |
| C．The sound of earthquakes. |
| D．The sound of the ice-breaking. |
As to the influence of noises on whales, which of the following statements is true?
| A．They are deaf to noises. |
| B．Noises at a certain level may hurt them. |
| C．They are easily confused by noises. |
| D．Noises will limit their ability to reproduce. |
We can know from the passage that many scientists think that the noise limit of one hundred twenty decibels would______.
| A．prevent them from doing their research work |
| B．benefit them a lot in their research work |
| C．do good to their health |
| D．increase the industrial output |
According to the passage, what will scientists most probably do in the future?
| A．They will try their best to decrease noise. |
| B．They will work hard to cut down noise pollution. |
| C．They will study the effect of different noises. |
| D．They will protect animals from harmful noises. |

A
Joyce Yuan and her host family
As I began to feel completely sick of the cold North American winter, spring break finally arrived! What made me even more excited was that we were going to Florida to enjoy the warm weather!
Just imagine wearing short sleeves or a swimsuit under the hot Florida sun!
Before the vocation started, we had a little episode at the airport. The alarm sounded when my host mom and I were walking through the security check. We were taken away to have further checks, but when they finally told us that we could go, we felt easy and amused. It was just because of the decorations on my pants and the tinfoil(锡纸) around my host mom’ chewing gum! －Just as a reminder, no overly fashionable pants or tinfoil on a plane!
Of course, I had a lot of first experiences during this special vacation. Since eight of us were living in a house, we had to share a room with my 4-year-old host sister. She is tiny compared to me, but she took up about two thirds of the bed. Moreover, because I was not used to sleeping in the same room with others, I was afraid of waking up and hardly slept at all.
Luckily, except for all that, everything went really well. My host family were really warm-hearted, and they wanted me to try everything new. With their “persuasion”, I was “forced” to go boating, which turned out to be really fun. We went through some canals and I saw manatees(海牛) and dolphins with my own eyes for the very first time!
When we finally landed in Wisconsin again, everyone looked brown and full of energy!

A mouse looked through a hole in the wall to see the farmer and his wife opening a package；what food might it contain? He was astonished to discover that it was a mouse trap!
Running to the farmyard，the mouse shouted，warning everyone，“There is a mouse trap in the house，there is a mouse trap in the house．”The chicken，with her head high，glared at the mouse and said，“Shut up．Little Ugly．This is a great concern to you，but it has nothing to do with me：I can’t be troubled by it．”
The mouse turned to the pig and told him．“There is a mouse trap in the house．”“I am so sorry，Mr Mouse，”said the pig sympathetically，“but there is nothing I can do about it but pray；you are always in my prayers．”
The mouse turned to the cow，who said，“A mouse trap，am I in great danger，huh?”
Now the mouse had to face the farmer’s mouse trap alone．
That very night a sound was heard through the house，like that of a mouse trap catching its prey．The farmer’wife rushed to see what was caught．In the darkness，she did not see it was a big poisonous snake whose tail the trap had caught．The snake bit the farmer’s wife．The farmer rushed her to the hospital．She rerturned home with a fever．It is said that drinking fresh chicken soup will help treat fever，so the farmer took his sharp knife to the farmyard for the soup’s main ingredient．His wife’s sickness continued，so friends and neighbors came to sit with her around the clock．To feed them，the farmer killed the pig．The farmer’s wife did not get well，in fact，she died，and so many people came for her funeral．The farmer had the cow killed to provide for all of them to eat．

I graduated from the university with a degree of engineering．It is a good field but my heart was not in it．I wanted to be an actor or work in the entertainment industryliving a creative life．My choice of engineering was really a mistake but I realized too late．As soon as I graduated，I moved straight to Los Angeles—the home of the film and television industry!
I tried to get a job in that field．I often worked as an extra in movies and TV shows—standing in the background while actors are in the foreground．This was fun for a while，but I wanted a real acting job，where I was speaking! Sadly，in Los Angeles，there is too much competition．Every race and age is represented：old，young，black，white，Asian，and Midwestern types like me．Being an extra couldst make enough money for me to live in Los Angeles．I had to do something else for money．
After three years of trying，I gave up my dream of being an actor and started a different career．I then tried network marketing，but in the end，that failed．Seven years after graduating from college，I was still in debt，still searching for a satisfactory life．I decided to go back to engineering．
However，I was starting to get disappointed with my life．Why is life not like what I expected? I expected to have made a lot of money，gotten married，with a house and nice cars，kids，freedom，etc．Millions of people lead lives with their dreams on theshelf , existing but not really living. I wanted my life to be different，more satisfactory，more alive．I wanted a life filled with adventure，romance，friendships，Successes，and dreams realized．But America was not providing that for me．

The world’s biggest Internet search engine，Google，has proven once again to be king of the Web．Users can download“Google Wi-Fi”software and then enjoy free Wi-Fi service available in some US cities since last Tuesday．
Wi-Fi is short for“Wireless Fidelity”(无线上网)．It allows laptop computers and personal digital assistants to connect to the Internet at high speed by radio signal．
A person with a Wi-Fi enabled computer can connect to the Internet when near one of the network’s access points．The place covered by one or several access points is called a hotspot．Google has already set up two“hotspots”in the US city of San Francisco which provide a free Wi-Fi service．
The Wi—Fi technology even allows users to enjoy a free Internet phone service．
Some scientists argue that Wi-Fi may replace mobile phone networks．
Wi Fi is still limited to a few cities．where there are“hotspots”．But its capability (容量)of sending information has already done better than that of the mobile phone network，even that of 3G(Third Generation telecommunication technology)．Some scientists have started to call Wi-Fi 4G．
In addition to a high speed Internet connection，Wi-Fi has other advantages com pared to mobile phones．Wi-Fi is global．The same Wi-Fi system works in different countries around the world．Different from using cell phones，you don’t need to change computers to use Internet phones when you go to other places and most importantly，many Internet phones cost you nothing at all．
