隧道与广播
How come we can hear FM longer in a tunnel than AM?
为什么在隧道中调频广播比调幅广播的信号要好一点?
It"s because FM stations transmit at higher frequencies. They generally go from eighty-eight to one-hundred-and-eight megahertz. That"s over a hundred million cycles per second.
这是因为调频广播台的传播频率要频繁些。通常在88到108兆赫。即每秒转1亿圈。
As a result, a single radio wave from an FM station is only a few meters long, about the size of a car. An AM station is putting out radio waves that are hundreds of times as long!
因此,调频广播电台发出的一个电波的长度只有几米,大概是一辆车的大小。而调幅广播站发出的电波长达几百米。
Long wavelengths tend to be absorbed or blocked as they try to enter the smaller tunnel. The higher-energy and shorter-wavelength waves from an FM station aren"t absorbed or blocked as much. Instead, they tend to bounce around and get reflected off of surfaces, much like the inside of a tunnel.
在穿越隧道时,长的波长会被吞并阻碍。而来自调频广播高能量,波长又短的电波则不会被吞并或阻碍。相反的,它们会被隧道表面反射回来。
Of course, they only bounce so far. If the tunnel is long enough, even FM stations fade out until you come out the other end.
当然,它们只会在某个区域内反弹。如果隧道太长的`话,即使是调频广播也会逐渐变弱直到驶出隧道。

Salt vs. Ice
食盐大战冰块
Y: Why does salt melt ice?
为什么食盐能让冰块融化?
D: It lowers the melting and freezing point of water.
是因为食盐将水的熔点和冰点降低了。
Y: Oh,OK.Wait,I don"t get it. Doesn"t that mean the salt make ice colder?
等一下,我不明白。这就意味着食盐让冰的温度变得更低吗?
D: Let me explain.Pure water freezes at thirty-two degrees Fahrenheit,right? At that temperature we can say that the rate of freezing is the same as the rate of melting.
我解释一下。纯净水的冰点是32华氏度,对吧?这个温度既是冰点也是熔点。
Y: So in other words, at water"s freezing point there"s a sort of equilibrium between freezing and melting.
也就是说,水的冰点就是结冰和融化的*衡。
D: Right.Throwing salt on ice upsets the balance.
是的。在冰上洒盐扰乱了这种*衡。
Y: Upsets it how?
怎么打乱的呢?
D: The salt dissolves into the liquid water, which means that some of the water molecules are replaced by salt. Since there are now fewer liquid water molecules to be captured and frozen by the ice, the rate of freezing drops.
盐溶解在水中,就是说一部分水分子被盐取代了。既然结冰的液态水分子减少了,冰点自然降低了。
Y: I think I get it.And Since the rate of melting stays the same, there"s more melting going on than freezing. And so the ice melts.
我明白了。水的熔点不变,融化的水分子比结冰的多,所以冰块就融化了。
D: Right.
对。
Y: Interesting.
很有趣。
D: In fact, anything that dissolves in water will do the trick. You could pour sugar on ice and it willmelt. But I guess since salt is cheaper it"s used more often.
其实,任何溶于水的物质都可以使冰融化。把糖洒在冰上,冰也会融化。但是我想也许由于盐比较便宜,所以经常被使用。

Michelle Howard received her fourth star at a ceremony at Arlington National Cemetery with her family and fellow servicemen looking on.
"If you don"t believe today was the first - when I called to order, a four-star shoulder board for women - they didn"t exist. [A] special contract was let and you folks are seeing the first set in the history of the United States Navy," said Howard.
Secretary of the Navy Ray Mabus was the promoting officer.
"The Navy picked the best officer to be the VCNO. That"s the only thing that happened here today," said Mabus.
Since 1982, when she graduated from the U.S. Naval Academy, Howard has achieved many historic "firsts" in her career. She was the first African-American woman to achieve three-star rank in the U.S. Armed Forces, as well as being the first woman to achieve the rank of admiral in the Navy. She also was the first African-American woman to command a naval ship.
Chief of Naval Operations Jonathan Greenert said the honors mean extra obligations.
“She will bear the burden of a role model, and she is ready to bear that very well, and I am very excited about that because we need lots more women in the Navy,” said Greenert.
Howard was in the Pentagon during the September 11, 2001 terrorist attack, and in 2009 participated in the naval task force dispatched to rescue the U.S.-flagged merchant vessel Maersk Alabama and its captain Richard Phillips, who had been kidnapped by Somali pirates.
"I was just three days in the job when we got word that Captain Philips had been kidnapped," recalled Howard.
American women serving in the military have broken many barriers in recent years, and can compete for positions that were once were closed to them. Howard said her promotion can serve as further encouragement.
"My rank today lets them know that they can go from junior enlisted to MCPON (master chief petty officer) in the Navy or from ensign to admiral," said Howard.
Howard is the third woman in the U.S. military to reach a four-star rank. One is in the Army and the other in the Air Force.
“We, as a Navy and as a nation, have just got to quit wasting the talent and the ability based on race or gender or anything else," said Mabus.
Officials from all military service branches have announced plans to open combat positions to women who meet physical or performance standards by 2016.

Scoop That Poop
我好“无辜”的
Actually, dog poop turns out to have a pretty big environmental impact. If you think that two in five households in the U.S. have at least one dog and that about forty percent of Americans don"t clean up after their pooches, well, all that poop really adds up. In fact, it"s what scientists call the Fido hypothesis.
狗狗便便严重污染环境。如果美国2/5家庭就养一只狗狗且当中大约40%的主人不收拾狗狗的便便。所有这些便便加起来也就是科学家说的.“狗狗”假说。(Fido是对狗狗通用的称呼)。
Hey, my dog"s name is Fido.
我的狗狗就叫Fido。
They conjecture that a lot of that waste ends up in waterways. Recent studies, in fact, suggest that dogs are in third or fourth place on the list of contributors to bacteria in water. Talk about gross—fecal matter is full of disease-causing bacteria like E. Coli, salmonella, and giardia.
科学家推想,水道阻塞的罪魁祸首就是这些便便。近日有研究表明,造成水里滋生细菌的“元凶”狗狗排第三或第四。令人作恶的这些细菌可以致癌,比如:大肠埃希菌、沙门氏菌、鞭毛虫
Now that bacteria-tracking methods have gotten better, scientists estimate that in some areas, 20 to 30 percent of the bacteria in a stream comes from dogs.
细菌源追踪技术的日臻完善,科学家估计,部分地区20%到30%的细菌是由狗狗造成的。
Really? That can"t be good!
真的吗?那可不妙!
And the thing is, pollution from dogs is relatively easy to control. All you have to do is scoop when they poop.
其实,狗狗造成的环境污染相对来说很容易避免,你需要做的只是在将狗狗的便便铲干净。

Recently, every morning when I wake up, I find my air-conditioner automatically turned off . I didn’t understand why at first , but soon I learned that there was a great shortage of electricity sup* in our city – my air-conditioner turned off because of a power failure midnight.
With the rapidly developing industry and the ever-increasing population, demand for electricity sup* is soaring. Besides, summers in recent years are much hotter than before , so most working places and households are air-conditioned , which consumes additional electricity.
Face with such a hard nut , we have to find ways to crack it . Above all , in western areas China , there is surplus of electricity sup*. So , cities that are thirsty for electricity may ask for remote help. Then ,when we have electricity , we should remember to save it . Set your air-conditioners at 27C and you won’t feel less comfortable than when they are at 26C . In fact , some factories already shift their working hours to avoid the peak time of electricity consuming. My parents don’t work from Monday to Friday as before – they work form Saturday to Wednesday and have the following two days off instead. This is also a way out , isn’t it?

Away from Net-bar Campaign
范文:
It has been reported that a middle school in Xuzhou City has recently launched a campaign named “Away from Net-bar”. More than a thousand students have signed for their solemn promise that they will not spend a single minute in the net-bars. With the nearing of the summer vacation, this campaign is especially meaningful for the healthy development of the minors.
The internet has brought people great convenience in getting information, entertainment and contact with others, and it has also benefited some businessmen, especially the owner of net-bars. While it is true that most net-bars are running legally, it is also true that some are offering unhealthy programs that involve violence and sex content. Since most middle school students are prone to be influenced and they can hardly tell which bars are doing well and which ones are not, it is only advisable that they stay away from all. Besides , staying away from net-bars also does good to students’ physical health. By passively sitting too long in front of the com*r screen, both their eyesight and physique suffer.
Obviously , the Away from Net-bars Campaign is an activity that is worth advocating and it merits other schools’ reference
Online Education

2.我认为这股热潮的的原因是……
3.我对网络教育的评价
范文:
Being online is no longer something strange in our life. To some degree, it has become part of our daily life. We can do a lot of things online, such as searching for information and communicating with friends far and near. But recently another helpful online activity has become very “in”. That is online education.
Why could online education be so popular within such a short period of time? Among other reasons, the quick development of the internet should be an essential one, which makes all our dreams of attending class in the distance possible. Another underlying reason is the quick development of both society and technology. Today ,modern science and technology is developing with lightening speed. To catch up with this development we all feel an urgent and strong desire to study. However , due to the great pace of modern society , many people are too busy to study full time at school. Online education just comes to their aid.
Personally , I appreciate this new form of education. It’s indeed a helpful complement to the traditional educational means. It can provide different learners with more flexible and versatile ways of learning. Most of all ,with online education, we can sick to our jobs and at the same time study and absorb the latest knowledge.
