Do you know that people without friends are more likely to die an early death? It's true.However,not all the friends are helpful to up your chances of living a long,happy life. The following types of friends are just what you need to keep the doctor away. A Loyal Best Friend Sometimes a loyal best friend is the only thing you need to stay calm. Everyone needs a non-judgmental friend who will support them no matter what.This is the kind of friend who knows all of your deepest and darkest secrets, but still loves you all the same. An Honest Confidant There are certain situations in life where we need to hear the harsh truth. It is really hard for you to face it, but that's what the honest confidant is for. Friends are supposed to be honest with each other. If you find someone who is bravely honest with you (in a constructive way), then hold on to this person! People like that are hard to come by these days. A Polar Opposite If you only develop friendships with others who follow the same beliefs, customs, and values as you do, chances are you're kept away from the rest of the world. Try to break out of your comfortable zone and befriend people who hold opposing views. You'll learn to accept people who don't see the world exactly the way you see it.  A Work Pal Do you know that with a full--time job, you spend at least 50%of your waking hours at work? Depressing, isn't it? The more isolated you are at work, the more depressed you get. That's why it makes sense to get a work pal to chat with to help you get through the week. You spend 50%of your waking hours at work, and so does your work pal. You'll find it much easier to complain about work with someone than to eat lunch alone every day. With them in your life, you're bound to live a long and happy life! A loyal best friend must   _   according to the passage. A) be one of family members B) love you whoever you are C) stay with you most of the time D) be good at keeping you quiet

(Question)
In 2013, a report from The Nero England Journal of Medicine showed that increased body weight is related to the death rate for all cancers.  This is based on a study involving about 900,000 people, spanning many years.      The study, started in 1992 by the American Cancer Society, included men and women from all 50 states.  The youngest participants were 30  years old,  and the '8verage age was 57. By December 2008,  24%  of the participants  had died,  just a quarter of them from  cancers.  In analyzing  the  results, researchers  attempted   to  take account of  such  potential factors as smoking drinking alcohol,  taking aspirin and a wide variety of other factors that might otherwise affect the results.     The results are clear the more you weigh,  the greater your risk of dying of cancer will be (up to 52% higher for men and 62% for women). In men as well as women, the only cancers that did not have a strong connection with weight were lung cancer and-brain cancer.  For women, the strongest correlation with weight was uterine cancer ,which is 6.5 times higher for women  with a BMI(Body Mass Index)of 40 or more.  For men,  it was liver cancer,  which is 4.5 times higher in most obese men.     Smokers tend to be more successful in keeping weight off than non-smokers ,slightly reducing the risk ,But many of them don't have good lungs .Thus ,in another way ,they also face  risks.     As for why extra weight leads to excess cancer death rate ,there's no clear agreement .But the decrease in vitamin D in obese people seems a likely factor .Vitamin D is known to have a  role in preventing cancer .Also, there is a simple fact that obesity makes the management of  cancer more difficult .Although for now there is no simple answer to why obesity increases a person's cancer risk ,all we know for certain is that the risk is real. The passage is mainly concerned with the relationship between  _  . A) diet and cancer B) body weight and cancer C) sex and cancer D) smoking and cancer

Ques: It does not come as a surprise that Dubai has a growing problem with tragic.The local rulers have explored all the conventional ways to get traffic moving again,including higher prices for parking,fuel and insurance.But at a recent conference in Hamburg,Hussain Lootah said that the city may adopt a more strict approach:setting an income level for vehicle ownership. Mr Lootah's approach is unlikely to be copied widely,but mayors of other big cities around the world are starting to think about taking severe actions of their own,including complete car bans in inner cities.But the efforts may not be enough to reduce traffic and pollution.The problems will only get worse:the number of vehicles sold globally each year will grow from around 80 million today to more than 100 million by the end of the decade,according to IHS Automotive.[] There are already a handful of car-free communities around the world.But these are typically small and often tourist destinations that seek to create a throwback in time,such as Sark Island,in the English Channel.The largest ear-free urban area is probably Venice,where it is impossible to build roads and bridges to link the more than 100 small islands the city sits on. Yet pedestrian malls and other car-free zones keep popping up in cities around the world.Some cities are considering ways to limit central city access to"green"machines,such as battery-electric vehicles.Hamburg is perhaps the furthest along. Such extreme plans may fly in a city such as Hamburg.But in many other cities the political resistance even to less far-reaching measures is hard to overcome.Michael Bloomberg,New York's former mayor,tried twice to introduce a jam charge for much of Manhattan,but his plans were rejected by state lawmakers. What causes Venice to be the largest car-free urban area? A) Its natural geographical characteristics. B) Its too many tourist destinations. C) Its reduced number of cars. D) Its government law on car free.
Ans: A


Can you imagine living in a house built by recycled waste? Texas home builder Dan Phillips transforms trash into artful treasures, creating beautiful floors with wood pieces, kitchen counters from ivory -colored bones and roofs out of license plates  . The fantastic houses which spring from his imagination are made almost entirely of materials which would otherwise have ended up in a garbage area. " People have been doing this for hundreds of thousands of years; using whatever is available to build shelter, " Phillips said."If you think about carefully what could be used, then building materials are everywhere. The thirteen homes he has built so far would fit better in an art museum than the residential streets of Huntsville, a conservative town of about 35 ,000 people. Living in these houses is a bit like living in a roadside attraction."Almost every day, somebody knocks on the door and says ' Is there any way that we could see?' "said Edie Wells, an artist who rents a room in the Bone House.Her home features a stairway made of bones, floors covered in wine corks   and beer bottle caps.Wells said visitors are most impressed when they see a bathroom with its walls, floor and ceiling entirely covered with broken mirror pieces. In addition, each house is highly energy efficient with plenty insulation   , an on-demand solar hot water heater and a system that can collect and recycle rainwater to clean the toilet and wash clothes. Phillips founded Phoenix Commotion 12 years ago with the aim of creating a new model for sustainable housing.For as little as $ 10,000 it builds affordable homes for single parents, low-income families and artists. The company has used hundreds of tons of construction waste by recycling the materials into habitable buildings. Phillips tries to spread his recycled-house idea by speaking at events across the United States, and by using the Internet to reach out to like-minded individuals.Phillips said: "I'm not going to be saving the world anytime soon.But there needs to be at least some... Which of the following is NOT the advantage of the homes built by Phillips? A) environmentally-friendly B) energy efficient C) convenient D) cheap
