Secondhand smoke isn’t just a health threat to people.It can also hurt dogs and cats,veterinarians say.
According to the Centers for Disease Control and Prevention,more than 126 million Americans who don't smoke are exposed to secondhand smoke in their homes,vehicles,workplaces,and public places.This exposure causes thousands of lung cancer and heart disease deaths among nonsmokers every year,according to the California Environmental Protection Agency.
“Making the leap from the effects of secondhand smoke on humans to their effects on pets isn't a big one,” says veterinarian (獸醫(yī)專家) Carolynn MacAllister of Oklahoma State University.
“There have been a number of scientific papers recently that have reported the significant health threat secondhand smoke poses to pets,” MacAllister said.“Secondhand smoke has been associated with oral cancer and lymphoma in cats,lung and nasal cancer in dogs,as well as lung cancer in birds.”
Studies have also shown that dogs living in a smoking household are susceptible to cancers of the nose and sinus area,particularly if they are a long-nosed breed,because their noses have a greater surface area that is exposed to carcinogens and a greater area for them to accumulate.Dogs affected with nasal cancer normally don't survive for more than one year.
“Short and medium-nosed dogs are more susceptible to lung cancer,because their shorter nasal passage aren't as effective at accumulating the inhaled secondhand smoke carcinogens,” MacAllister said.“This results in more carcinogens (致癌物質(zhì)) reaching the lungs.”
Birds are also at risk for lung cancer,as well as pneumonia,because their respiratory systems are hypersensitive to any type of air pollutant.
To help prevent animals from being adversely affected by smoking,pet owners who smoke should have a designated smoking area that is separated from the home or stop smoking altogether,MacAllister said.

On October 23, 2011, David Pologruto, a high school physics teacher, was stabbed (刺) by his smart student Jason Haffizulla. Jason got straight A’s and was determined to study medicine at Harvard, yet this was his downfall. His physics teacher gave Jason a B, a mark Jason believed would undermine (損害) his entrance to Harvard. After receiving his B, Jason took a butcher knife to school and stabbed his physics teacher.
How can someone as smart as Jason do something so dumb? Studies show there is little or no correlation between IQ and emotional intelligence.
During my early university years, I regarded myself as an intelligent guy. I got good marks in mathematics, physics, and other subjects. I thought such skills would surely give me a bright future. After one year of study with decent marks, I began to see two major classes of students. The first category of students turned up to few lectures, partied every weekend, enjoyed a great social life, and did minimal work to pass courses. The second category of students were intelligent and hard workers who got good grades and were very focused on their studies. Surely would these intelligent and hard-working students find the great jobs before the other lazier class of students?
Not so. Students are often shocked upon graduation that their qualifications are not as important as they once thought. Graduates enter the workforce only to realize that co-workers hate them and less intelligent people are the ones receiving promotions.
Educational skills are useless in some industries when interpersonal skills are absent. You can have great ideas, theories, and solve complex problems, but if you cannot effectively communicate in a persuasive and exciting manner by relating to your fellow humans, you will face an uphill battle in whatever challenges you encounter. It’s not that people dislike you because of your intelligence; it’s that people dislike you because you’re rude and not understanding. The intelligent person with poor communication skills is insensitive or unaware of others’ emotions.
小題1:Jason Haffizulla stabbed his physics teacher because       .
A.he was unfairly treated by his teacher
B.he was disappointed with his downfall
C.he was not smart enough at studies
D.he got a worse mark than usual
小題2:We can infer from the third paragraph that the author        in his early university years.
A.didn’t think communication skills were as important as intelligence
B.didn’t work hard
C.belonged to the first category of students
D.could keep a balance between social life and studies
小題3:Intelligent people are hated because       .
A.they can solve more complex problems
B.they can’t settle the challenges they meet
C.they are envied for their intelligence
D.they are not understanding enough
小題4:The main purpose of the text is to tell us       .
A.the relationship between IQ and emotional intelligence
B.what kind of students can succeed in college
C.smart people may have poorer communication skills
D.intelligent students will meet more challenges at work

For the most part, you are probably only exposed to the music that is played on your favorite radio stations and TV shows, music Web sites, or the music that your friends and family members enjoy. While you probably know a lot about your favorite type of music, it can be a rewarding experience to enlarge your horizons(眼界), discovering artists and types of music that you’re not familiar with. Who knows, you might discover you like certain types of music you never even considered.
Have you ever wondered about the history and influences of your favorite types of music ? For example, did you know that rock ‘n’ roll originated(起源)from the blues, and that the blues began as a form of musical expression for African Americans during slavery(奴隸制度)?Did you know that most hip-hop is heavily influenced by early rhythm blues and jazz ?
There are many fun ways to learn about different musical styles and their historical roots. For example, if you like hip-hop, listen to some of your favorite CDs and take note of the samples the performers used to create the songs. There is a possibility that the artist used parts of older songs to create the music. You can go to the library or online to learn more about the artists and listen to more of their music by checking out CDs from the library or downloading songs online for a small fee.
You can learn so much about culture and history just by paying attention to different types of music and what is being expressed in the songs. There are so many different styles of music to learn about, and you owe(欠)it to yourself to make an effort to listen to and learn about them.

   Animals can move from place to place, but plants cannot. When an animal is under attack, it can run away or fight back. Plants certainly cannot run away, and they lack teeth and claws. But plants can defend (保護(hù)) themselves by using both physical and chemical means.
  Some plants have their own ways to keep animals away. For example, the leaves of the holly plant have sharp spines (刺) that discourage grass-eating animals. Holly leaves on lower branches have more spines than leaves on upper branches. This is because the lower leaves are easier for most animals to reach.
  Some plants, such as the oak tree, have thick and hard leaves that are difficult for animals to eat. Some grasses may contain a sandy material; eating such grasses wears down the animal's teeth.
  Many plants also have chemical defenses. Some plants produce chemicals that taste bitter or cause an unpleasant reaction. Some plants may fight against an attack by increasing the production of these chemicals. When a caterpillar (毛蟲) bites a tobacco leaf, the leaf produces a chemical messenger. This messenger sends to the roots the information to produce more nicotine. The higher levels of nicotine discourage the caterpillar.
Many plants depend on both physical and chemical defenses. A certain plant in China, for instance, has prickly (多刺的) leaves, and each prickle contains poisonous venom (毒液) A single experience with this kind of plant will teach an animal to stay away from it in the future. 
小題1:To defend themselves, oak trees use________.
A.chemical means B.physical means
C.bitter chemicals D.sandy materials
小題2:How does tobacco protect itself against an attack from a caterpillar?
A.Its leaves fight against the attack by physical means.
B.Its roots send a messenger to discourage the caterpillar.
C.Its roots increase the production of nicotine when it is attacked.
D.Its leaves produce poisonous sand to drive the caterpillar away.
小題3:What would be the best title for this passage?
A.Plants and Animals
B.How Plants Defend Themselves
C.Attacks and Defenses

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 (牌照).
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 (軟木塞) 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 (隔熱材料) , 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 visibility for this model in this century.
小題1:Which of the following is NOT the advantage of the homes built by Phillips?
A.environmentally-friendlyB.energy efficient
C.convenientD.cheap
小題2:What do we know about Dan Phillips?
A.He is serious and hard-working.
B.He is full of imagination and intelligence.
C.It didn't take him long to build the houses.
D.He didn't give speeches in the United States.
小題3:According to the passage, the houses are like artful treasures because they are           .
A.made of bonesB.museums
C.a(chǎn)dmired by peopleD.made of various trash

Animal experts in Croatia say a bear has learned how to trick people to let him in by knocking at the door.
They believe the 220- kilogram brown bear probably learned the trick while nudging (輕推) a door to get it to open.
Experts have a guess that the nudging was mistaken by the owners for knocking and that the bear, pleased by the result, repeated the trick.
The Loknar family from Gerovo in western Croatia said the bear had knocked at their door three times and they were now refusing to answer the door.
‘We jumped out of the window as he came in through the door and went into the kitchen to take some food for the first time.” Mum Nevenka Loknar told a reporter from a local newspaper. “I opened the door and saw him standing there and I didn’t believe my eyes at first, then I ran for it as he walked in as if it was the most normal- thing in the world.”
Bears are a common thing in the woods around here, but no one has ever heard of a bear that knocks at the door.
Mum Nevenka Loknar said, “The bear is so intelligent. It’s incredible. We’ve tried to put up lots of obstacles to stop him coming in, like a wire fence but he still gets through. I wouldn’t be surprised if he knew how to use wire cutters (鋼絲剪).”
小題1:According to experts in Croatia, how did the bear learn the trick?
A.By knocking at the door several times.B.By accident.
C.By learning from the owner of a family.D.By imitation.
小題2:What does the underlined word “it” in paragraph 5 refer to?
A.Eating at the kitchen.B.Knocking at the door.
C.Walking into the house.D.Answering the door.
小題3:It is ________ in Gerovo that a bear knocks at the door.

In a great many cities, hundreds of people ride bikes to work every day. In New York, some bike riders have even formed a group called Bike for a Better City. They declare that if more people rode bikes to work, there would be fewer automobiles in the downtown part of the city and so less dirty air form car engines.
For several years, this group had been trying to get the city government to help bike riders. For example, they want the city to draw special lanes(車道) for bikes on some of the main streets, because when bike riders must use the same lanes as cars there are accidents. Bike for a Better City feels that if there were special lanes, more people would use bikes.
But no bike lanes have been drawn. Not everyone thinks it is a good idea—they say it will slow traffic. Some store owners on the main streets don’t like the idea—they say that if there is less traffic, they will have less business.
The city government has not yet decided what to do. It wants to keep everyone happy. On weekends, Central Park—the largest place open ground in New York— is closed to cars, and the roads may be used by bikes only.
小題1:In New York, a group of bike riders__________.
A.a(chǎn)re keeping practicing for health
B.have no cars of their own
C.a(chǎn)re complaining there are not enough buses
D.a(chǎn)re trying to settle the problem of air pollution
小題2: The bike riders suggest that __________.
A.bikes should be used instead of carsB.bike lanes should be drawn
C.fewer buses or cars should be usedD.the number of special lanes should be decreased
