Mobile phones help us easily find people anywhere at any time. A mobile phone can include many things, such as games, music and Internet surfing. Today, 4,600,000,000 people around the world have mobile phones, according to CBS News.
However, using mobile phones too often may cause cancer(癌癥). It’s reported that people who used a mobile phone for 10 years or more were more likely to get cancer. The advice below may help you reduce the risk of cancer:
★An earphone gives out much less radiation(輻射) than phones. However, you should take it off your ear when you’re not talking to anyone.
★Your phone gives out radiation when you talk or text(發(fā)短信), but not when you’re listening or getting messages. Listening more and talking less can lower the risk of cancer.
★Hold the phone away from your body when you’re talking, not against your ear. Also, don’t keep it in your pocket.
★Phones gives out less radiation to send texts than to carry a person’s voice. Texting also keeps radiation away from your head.
★Do not use your mobile phone when the signal(信號(hào)) is weak. Fewer signal bars on your phone mean that the phone needs to give out more radiation to work. Make and take calls when your phone has a strong signal.

Every year thousands of people get hurt or die when they are crossing the road. Most of these people are old people and children. Old people often get hurt or die because they can’t see or hear very well. Children usually meet with accidents because of their carelessness. They forgot to look and listen before they cross the road.
How can we lessen (減少) traffic accidents? All of us must obey the traffic rules. For the drivers, they shouldn’t drive too fast. If they drive too fast, it will be very difficult to stop the cars in a very short time. For the pedestrians (行人), it’s very important to be careful when they are walking on the road. Therefore, when we walk across the road, we must try to walk along the pavements(人行道). We must stop and look both ways before crossing the road. Look left first, next look right, then look left again. Only when we are sure that the road is clear, we can cross it. The right way to cross the road is to walk quickly. It’s not safe to run. If people run across the road, they may fall down. Teens(青少年) should try to help children, old people or blind people to cross the road, and never play in the street.

The practice of students endlessly copying letters and sentences from a blackboard is a thing of the past. With the coming of new technologies like computers and smart phone, writing by hand has become something of old skill. However, while today’s educators are using more and more technology in their teaching, many believe handwriting skills are still necessary for students to be successful--both in school and in life.
Virginia Berninger, professor of educational psychology(心理學(xué)) at the University of Washington, says it’s important to continue teaching handwriting and help children learn the skill of writing by hand.
Berninger and her workmates carried out a study that looked at the ability of students to complete different writing tasks---both on a computer and by hand. The study, published in 2009, found that when writing with a pen and paper, people wrote longer articles and more complete sentences.
In a more recent study, Berninger looked at what role spelling plays in a student’s writing skills and found that how well children spell is tied to how well they can write. “Spelling makes some of the thinking parts of the brain active which helps us get our vocabulary, word meaning and ideas. It is allowing our written language to connect with ideas.” Berninger said.
Spelling helps students translate ideas into words in their mind first and then to transcribe(轉(zhuǎn)換) “those words in the mind into written symbols(標(biāo)志) on paper or keyboard and screen,” the study said. Seeing the words in the “mind’s eye” helps children not only to turn their ideas into words, says Berninger, but also to notice spelling mistakes when they write the words down and to correct them over time.
“In our computer age, some people believe that we don’t have to teach spelling because we have spell checks,” she said. “But until a child has spelling ability of about a fifth grade level, they won’t have the knowledge to choose the correct spelling among the choices given by the computer.”
【小題1】Which of the following best shows the role of spelling?

A．Spelling improves one’s memory of words. 
B．Spelling ability is closely tied to writing ability. 
C．Spelling benefits the translation from words into ideas. 
D．Spelling slows down finding exact words to express ideas. 
【小題2】What does “mind’s eye” in paragraph 5 mean?
A．Window. B．Emotion.  
C．Picture. D．Imagination. 
【小題3】What can we learn from the passage?
A．Computers can help people with their choice of words. 
B．Spell checks can take the place of spelling teaching. 
C．Handwriting still has a place in today’s classrooms. 
D．Spelling ability develops fast in the fifth grade.

The Oxford English Dictionary (OED, 牛津英語(yǔ)詞典) is thinking of adding the Chinese word tuhao (土豪) to its 2014 edition (版本).
The word has become popular in China during the past few months to describe newly rich people who spend money in extravagant（鋪張的，浪費(fèi)的）ways. Tuhao has caught on in Western countries, too, to describe similar people in their countries.
The adoption (采用) of the word by foreign countries is an example of China’s spreading influence in the world not just economically, but also socially and culturally. People are paying attention to what is happening in China and are picking up some Chinese words in the process, especially those words that express unique (獨(dú)特的) Chinese ideas that cannot be easily translated (翻譯) into English.
The OED is also thinking of adding hukou (戶口) and dama (大媽) to the already 120 Chinese words in its dictionary. Hukou refers to (指的是) China’s system of residency permits (戶籍系統(tǒng)) and dama refers to middle-aged Chinese women whose gold buying habits influence the global gold markets. The news that the OED was adding these words has met with some criticism (批評(píng)). Some people say the words embarrass (使人尷尬) China, but others insist that in a globalized (全球化的) society it’s natural for words to spread and be adopted elsewhere. In fact, a word like tuhao expresses the humor of China. It’s easy to pronounce (發(fā)音) and very accurate (精準(zhǔn)的) at poking fun at (嘲弄) rich people who have more money than taste.
【小題1】_____ may be adopted in the Oxford English Dictionary in 2014 according to the passage.

A．Tuhao B．Hukou C．Dama D．All above 
【小題2】_____can be called “tuhao” according to the passage.
A．All newly rich people 
B．People who own their money easily 
C．People who love money very much  
D．Newly rich people who spend money in an extravagant way 
【小題3】The underlined word “caught on” (in Paragraph 2) most probably  means________.
A．流行 B．繼續(xù) C．接受 D．蔓延 
【小題4】The last paragraph mainly talks about __________________.
A．humor of Chinese style 
B．criticism on the adoption of Chinese words into OED 
C．support on the adoption of Chinese words into OED 
D．different opinions on the adoption of Chinese words into OED

Millions of British people have ditched the traditional “thank you” and took the place of it with the less formal “cheers”, according to a survey.
Although the common person will say “thank you” nearly 5,000 times a year, one in three are more likely to add a “cheers” or “ta” where it’s needed to show they are fashionable.
One in twenty now say “nice one” instead, while the younger are more likely to offer a “cool” than a “thank you”.
“Merci”, “fab” and even “gracias” were also listed as common phrases to use, as “much appreciated(感激)”.
One in twenty who took part in the survey of 2,000 people by the Food Network UK for Thank You Day, which is marked on November 24, 2011, said a formal “thank you” was now not often needed in everyday conversation. More than one in ten adults said they regularly won’t say thank you if they are in a bad mood. Most people stated that saying thank you was something that their parents trained them. A huge 70 percent of those questioned will say thank you to a person’s face without even meaning it, while one fifth avoid(避免)saying it when they know they should.
It seems our friends and family get the stress of our bad manners. Half of them admit (承認(rèn)) they’re not good at thanking those closest to them. Many of them explain that they don’t say thank you because their family “already know I’m grateful”.
When spoken words won’t do, it falls to a nice text to do the job for most people.
One third will still send a handwritten thank-you note---but 45 percent admit it’s been more than six months since they tried to send one.
A quarter of British people say “thank you” with food, with 23 percent cooking a meal to show their appreciation to someone. Another 15 percent bake a cake.
It follows that 85 percent of people will be angry because of not getting the gratitude (感激)
they feel they should receive.
【小題1】Most of the people who took part in the survey say that they say “thank you” _______.

A．when they are in good mood
B．completely out of habit
C．when they feel truly grateful
D．purely out of politeness
【小題2】 The underlined word “ditched” in Paragraph 1 means “________”.
A．gave up B．used
C．shared D．knew
【小題3】It can be learned from the passage that _______.
A．different ways of expressing gratitude are all fashionable
B．people should avoid saying “thank you” nowadays
C．a(chǎn) thank-you note is still appreciated by most people
D．people in a bad mood never say “thank you”
【小題4】 Which of the following is TRUE according to the passage?
A．Most people express their gratitude to others by buying food for them.
B．About fifty percent of people try not to say thank you when they should.
C．Most people may feel natural when they fail to receive others’ gratitude.
D．Many people think it unnecessary to say thanks to their family members.
