X-rays are high energy waves that are invisible. 1.For example,doctors can see inside the human body and security guards at airports can see inside your handbag. In 1895,the German scientist,Wilhelm Rontgen,discovered X-rays by accident. He called them X-rays because he hadn't seen such a form of radiation before. 2.Wilhelm took the first X-ray picture of the bones of his wife's hand after the discovery. In 1901,he received the first Nobel Prize in Physics for his discovery.
X-rays are valuable in medicine because then can see through certain parts of the body. Doctors can take pictures to see which bones are broken or to find out which teeth have holes. The X-rays are strong enough to pass through the skin and muscles,but they cannot pass through hard objects like bones. In the picture,hard objects like bones are white area3.
There are some situations in which X-rays cannot give you a clear picture. Some organs,for example,may prevent X-rays from showing a broken bone. For this reason,computed tomography(CT)was invented. A person is put inside a scanner,which is a large tube-shaped machine. 4. A computer puts together all of these images,which can show doctors more than a normal X-ray can.
5.Patients must wear protective clothing for the parts of their body that are not X-rayed. Doc- tors and helpers who work with X-ray machines must wear lead aprons and stand behind screens.
A.Then the person is X-rayed from all sides.
B.Objects that X-rays go through appear dark.
C.In mathematics,X means something unknown.
D.An X-ray machine is used to take these pictures.
E.X-rays,however,can also do harm to your body.
F.However,they can be an essential tool for finding out what's wrong with you.
G.They are useful because they can pass through many things that normal light cannot.
Over a cup of iced tea at the midtown Radiance Tea House&Books,whose noise is not much louder than a coffee machine's,Gregory Scott Farber,a non-practicing lawyer who works as a research analyst, described SoundPrint he created as"Yelp for noise". SoundPrint allows users to search for and grade restaurants and bars according to their sound level. "laces are getting louder,"Farber said. "People tell me thirty or forty years ago you could go somewhere to eat and expect to have a conversation. "
Farber suffers from permanent hearing loss,caused by meningitis(脑脊膜炎)which he contracted when he was a baby. Like so many great inventions,Farber's invention arose from a desire to find love-or,at least,a place to have a date. "When I was dating,I put a lot of efforts into trying to pick quiet spots,"he said. "I'd google' quiet restaurants'. Then I would show up,but it would be noisy. " His hearing aid helped,but not enough. "Out of curiosity,I started taking decibel(分贝)measurements. "He sent a list of his favorite quiet places to friends in the hearing-loss community,and soon found many requests from his normal-hearing friends.
SoundPrint includes a sound-level meter,so diners and drinkers can take measurements using their smartphones,and upload data to the database. Farber said that the app brings no profit. SoundPrint covers about two thousand cities,though only fifteen have a significant number of users. Farber recently analyzed the data from 2,376 Manhattan restaurants and bars,and the findings are not good for ears. More than 70%of the former and 90%of the latter were rated as"loud"-defined as between 76 and 80 decibels,or as noisy as an air-conditioner.
1.What does Gregory Scott Farber do for a living?
A.He sells hearing aids.
B.He develops computer programs.
C.He defends people in a court of law.
D.He makes a detailed analysis of data.
2.Why did Farber create SoundPrint?
A.Because he wanted to earn more money.
B.Because he could hear nothing without a hearing aid.
C.Because he wanted to help his friends who suffer hearing loss.
D.Because he suffered hearing loss and wanted to find a quiet place for dating.
3.What can we learn from the last paragraph?
A.SoundPrint can be downloaded to user's phones.
B.SoundPrint can detect noise from air-conditioner.
C.SoundPrint is widely used in 2,000 American cities.
D.SoundPrints can analyze data from restaurants and bars

There are few things in life that are more irritating(令人愤怒的）：You are mid-conversation with a friend. Suddenly he bursts out laughing,making you think you've made a brilliant joke. But then he says:"Sorry,I wasn't laughing at you,I just saw something really funny on micro blog. "He even begins replying to a text message or checking his e-mails.
The Guardian described the scene that a friend's face buried in a screen"a distinct 21 st-century problem". The phenomenon even coins a new word"phubbing",referring to the act of snubbing(冷落） others in a social setting by looking at your phone instead of paying attention. According to research by advertising agency McCann in the UK,37 percent of people feel it is worse not to answer a message than it is to"phub"your friends.
Phil Reed,a professor of psychology at Swansea University who has studied Internet addiction disorder,said many phubbers show symptoms of addiction to their mobile phone.
Like pointing or picking your nose,phubbing is widely considered rude,which can be seen from the popularity of"Stop Phubbing"campaign,which started in Australia by 23-year-old Alex Haigh who wants to shame people who snub friends and family they are with in favor of checking their mobile phone.
The campaign's website claims that"97 percent of people claim their food tasted worse while being a victim of phubbing"and"92 percent of repeat phubbers go on to become politicians".
According to Katy Steinmetz,reporter with Time,phubbing"has a much greater potential to hamper（阻碍）real-life connections by making people around us feel like we care more about posts than their presence". She believes it is the reason why the campaign can resonate(产生共鸣）with people and is getting press around the world.
In the UK,Glamour magazine even imagined just how Jane Austen would have satirized(讽刺）those in need of social etiquette(礼节）when it comes to using their smartphone. Or,to paraphrase(意译）the novelist,how it is a truth universally acknowledged that a single man(or woman)in possession of a good smartphone must be in want of manners.

On January 12,a few days after registration for the course of Psychology and the Good Life,roughly 300 people had signed up. Within three days,the figure had more than doubled. After three more days, about 1,200 students,or nearly one-fourth of Yale undergraduates,were enrolled.
The course,taught by Laurie Santos,42,a psychology professor and the head of one of Yale's residential colleges,tries to teach students how to lead a happier,more satisfying life in twice-weekly lectures.
＂Students want to change,to be happier themselves,and to change the culture here on campus," Dr,Santos said in an interview. "With one in four students at Yale taking it,if we see good habits, things like students showing more gratitude,delaying less,increasing social connections,we're actually seeing change in the school's culture. "
Dr. Santos discovered that Yale students are interested in the class because,in high school,they had to give up their happiness to gain admission to the school,adopting harmful life habits that have led to what she called"the mental health crises we're seeing at places like Yale. "A 2013 report by the Yale College Council found that more than half of undergraduates sought mental health care from the university during their time there.
＂In reality,a lot of us are anxious,stressed and unhappy,"said Alannah Maynez,19,a freshman taking the course. "The fact that a class like this has such large interest speaks to how much students numb their emotions-both positive and negative-so they can only focus on their work,the next step and the next accomplishment. "
Students have long requested that Yale offer a course on positive psychology,according to Woo-Ky-oung Ahn,director of undergraduate studies in psychology,who said she was"blown away"by Dr. Santos' s proposal for the class.
Administrators like Fr. Ahn expected significant enrollment for the class,but none anticipated it being quite so large. Psychology and the Good Life,with 1,182 undergraduates currently enrolled,stands as the most popular course in Yale's 316-year history. The previous record-holder-Psychology and the Law-was offered in 1992 and had about 1,050 students,according to Marvin Chun,the Yale College dean. Most large lectures at Yale don't exceed 600.
