• 1．If you are dreaming of visiting one of those picture-perfect European towns filled with old-world attractiveness and scenic beauty，here is a look at the most beautiful small towns in Europe.
  Manarola
     Manarola，Italy，is filled with rainbow-colored homes along the Mediterranean coast.This attractive fishing town is famous for its unbelievable wine，and the paintings.There are no cars here，no traffic lights，or traffic noise.You can drive to Manarola，but you will have to park just outside the town and then take a shuttle bus or walk in on foot.
  Garmisch-Partenkirchen
     Garmisch-Partenkirchen，Germany，is an attractive mountain town，once two separate towns，one Roman and the other Teutonic.The 1936 Winter Olympics forced them to become one，though the two sides still have different characters.The town dates back to 15 AD，filled with narrow streets lined with historic three- or four-story buildings painted with religious scenes.
  Marsaxlokk
     The energetic trading port of Marsaxlokk，Malta，was built in 900 BC.Today，this picture-like town is the main supplier of fish to the island nation that sits in the Mediterranean Sea.It has no modern buildings to ruin its attractiveness.With such quiet surroundings，including the traditional fishing boats，it is a particularly charming place to visit.
  Port Magee
     In a country filled with beautiful towns，Port Magee，is a standout，sitting on the southwest coast of Ireland.This seaside fishing town has a row of brightly colored buildings along with a rich and colorful history.At The Bridge Bar，you will find live music many nights of the week along with nice food and a fine glass of beer.

• 2．I grew up without a father.Well，sort of，my parents divorced in the 1960s when I was a small child，and I stayed with my mother in Los Angeles.My father remarried and moved to a small suburb of Atlanta.For one month out of the year in the summer，I would fly back and spend time with my dad，so I had a father at times.
     Further，I had a series of stepfathers who ranged from wonderful guys to alcoholics to dangerous individuals.Having lived through such experiences，I find it amusing when people say that children really need a father in the home.Well，if he is a good father and a good man，then I agree completely.If he is not，then the child might actually be better off without him.We don't just need fathers—we need good fathers.
     I feel it fair to say I ended up a very successful adult，at least that's what people tell me.So how did I do it？I think it started with me having a bit of a chip on my shoulder.Normally this is not a good thing，but in my case it was rocket fuel for achievement.Not having a father in my life gave me something to prove，and it motivated me in an "I'll show you" way.
     I also tried very hard，even as a little boy to be self-sufficient.And that means I did not rely upon my parents except to the extent necessary.This kind of independence I believe is highly missed in this age of highly managed children with "helicopter" parents hovering（盤旋）above them constantly.
     I also think I never wanted not having a father in my life to be an excuse for myself.We make and allow excuses constantly these days，but I just never felt that feeling sorry for myself was going to get me anywhere.I think if children can adopt such mindsets early in their lives it can be helpful.

  .
  A．his father is a bad one

  C．children need a good father
  D．children really need a father

  A．He was very intelligent.
  B．He made excuse for himself.
  C．He was motivated by a father.

  （3）What does the underlined word "self-sufficient" mean in Paragraph 4？

  
  A．Able to support myself.
  B．Able to dress myself very quickly.
  C．Able to play by myself.
  D．Able to work on my own.
  （4）How can we describe the author from the passage？

  
  A．Friendly，clever and warm-hearted.

• 3．If you like texting and are trying to lose weight，a new study found that using texting to track diet and exercise habits may help you lose weight.
     Previous research has shown that keeping food and exercise diaries improves the likelihood of success when you are trying to lose weight.Using a computer or a pen and paper to record information，however，can be a burden and cause some people to give up.
     Duke University researchers said using text messages to track eating and exercise habits can save time，and increase the chances that people will stick with their weight-loss rules.
     The study included 26 obese women with an average age of 38.The women used daily texting as part of their weight-loss program.The text messages focused on tracking personalized goals，such as avoiding sugary drinks or walking 10，000 steps a day.Messages also provided brief feedback（反饋） and tips.
     Every morning，the women received a text from an automated（自動(dòng)的） system that said，"Please text yesterday's personal information of steps you walked and how many sugary drinks you had." Based on the women's responses to the text message，the system sent another text with personalized feedback and tips.
     After six months，the women who used daily texting lost an average of nearly 3 pounds，while another group of women who used traditional methods to keep food and exercise diaries gained an average of 2.5 pounds，according to the study，which was published in the Journal of Medical Internet Research.
     "Text messaging has become popular and may be an effective method to simplify tracking of diet and exercise behavior，" Dori Steinberg，who was responsible for this research，said.
     Steinberg said，"Text messaging offers several advantages compared to other self-monitoring methods.Unlike web-based diet and exercise diaries，data in a text message can be entered quickly on nearly all cellphone platforms，so it is very convenient to receive feedback.Besides，because of the limited number of words used in text messages，it saves time."
  
  （1）According to the study，traditional methods

  .
  A．a(chǎn)re easier for people to lose weight
  B．may cause people to give up losing weight
  C．provide brief feedback and tips
  D．a(chǎn)re easy to track diet and exercise behavior
  （2）Which is NOT true about text messaging according to Steinberg？

  
  A．It saves time.
  B．It saves money.
  C．It can be entered quickly.
  D．It is easy to receive feedback.
  （3）What's the best title for the text？

  
  A．Texting Helps Keep Healthy
  B．Texting Saves Time and Money
  C．Texting Can Help You Lose Weight
  D．Texting Provides Brief Feedback and Tips
  （4）What's Dori Steinberg's attitude towards text messaging？

  
  A．Unknown.
  B．Negative.
  C．Positive.
  D．Unconcerned.

• 4．Texting（發(fā)短信）walkers aren't just an annoyance to other walkers.Australian researchers armed with movie special-effects technology have determined scientifically that they're threats to themselves.Using motion-capture technology similar to that used for films，researchers concluded that texting while walking not only affects balance but also the ability to walk in straight line.
     "Some people like checking emails while walking to work in the morning，" said the study's co-author Hoorn，"but they may not know it has a serious effect on the safety of themselves." Other facts have also proved this.A tourist from Taiwan walked off a pier near Melbourne last month while checking Facebook，bringing a sudden and icy end to a penguin-watching visit.Another person who was too wrapped up in his phone to notice dangers walked straight into the fountain in front of a shopping mall.
     The Australian study involved 27 volunteers，a third of whom admitted having knocked into objects while texting.They were asked to walk 8.5 meters three times—once without phones，once while reading text and once while writing text，when eight cameras recorded their actions.
     They found the volunteers using the phone walked slower，and，more seriously，they locked their arms and elbows in like "robots"，which forced their heads to move more，throwing themselves off balance."In a pedestrian（步行的）environment，inability to maintain a straight path would be likely to increase potential for traffic accidents，" said Mr Hoorn."The best thing to do is step aside and stop，or keep off the phone."
     Authorities world-wide have taken note.Signs on Hong Kong's subway system advise passengers in three languages to keep their eyes off their phones.Police and transport authorities have highlighted the danger in Singapore，where the Straits Times newspaper recently declared cellphone-distracted road crossing as "bad habit No.2" contributing to the rising number of road deaths.Some U.S.states，including New York and Arkansas，are considering bans on what they're calling phone jaywalking.
  
  （1）According to the passage，people texting while walking usually

  .
  A．do not influence other walkers
  B．do harm to their eyes
  C．put themselves in danger
  D．can still walk straight
  （2）Which of the following words has the closest meaning to "wrapped up" in Paragraph 2？

  
  A．Absent-minded.
  B．Annoyed.
  C．Confused.
  D．Absorbed.
  （3）About the Australian study，we know that

  .
  A．the volunteers using phones while walking moved normally
  B．ten volunteers admitted having bumped into things while texting
  C．the volunteers were divided into three groups during the study
  D．texting walkers are exposed to greater possibility of traffic accidents
  （4）The last paragraph suggests that

  .
  A．a(chǎn)ctions have been taken against texting while walking
  B．Hong Kong's subway system forbids texting walkers to take the train
  C．New York has made laws to ban phone jaywalking
  D．cellphone-distracted road crossing is considered the worst habit in Singapore

• 5．There have been a lot of comments recently surrounding 5 G，the next generation of wireless technology.（1）

  ？How might it change our lives？
     5 G stands for fifth generation，meaning the next step in the progression of technology to replace the current 4 G system.Earlier "G" systems were designed to improve mobile communication operations.Each new technology brought major improvements in speed and greatly increased network capacity（容量）.（2）

  .It is expected to permit more users to do more things at a faster rate.
     However，technology experts say there is a major way that 5 G is different from the earlier systems.（3）

  .It will affect many more devices and industries than other "G" versions.
     5 G will help fuel future "smart cities" by connecting sensor networks.5 G is also expected to connect self-driving cars and support new technologies involving virtual reality（虛擬現(xiàn)實(shí)）.Higher 5 G speeds could also permit doctors to commonly perform remote medical operations.Factories and businesses could use 5 G technology to increase automation and improve the collection of information.
     （4）

  .The increased data flow across 5 G networks would give Internet attackers a lot more possibilities to steal and misuse data.In addition，the wider use of a 5 G wireless network means any breakdown of the system would have more widespread and severe results.Such difficulties could affect public safety.（5）

  ，or a network breakdown could cause self-driving vehicles to crash.
  
  A.Why is 5 G so popular
  B.What is this technology
  C.Every coin has two sides
  D.The new 5 G system promises more of the same
  E.It will move beyond mobile network technology
  F.A breakdown of 5 G networks may cause economic losses
  G.A failure during a doctor's remote operation could lead to death
