                                   B

          You've probably heard about the -dangers of smoking. The good news is that fewer teens smoke today than at any time since the 1990s. But here's  the bad news. Every day,nearly 4,000 kids in the U.S. try a cigarette for the first time. And every day,1,000 kids become regular smokers. Almost all teen smokers plan to quit within five years. But more than 60 percent are still smoking 7 to 9  years later.

           Most people hope every teen in the world stays away from cigarettes,but not the people who work for- tobacco companies. Before people knew that cigarettes were dangerous,tobacco companies openly marketed their products to teens. In the early 1900s,some cigarette packs included collectible baseball cards. In the 1940s and 1950s,tobacco advertisements often featured actors and actresses. That ended in 1964,when the U.S. government released the results of a major scientific study on the effects of smoking on health. New laws banned cigarette advertising on TV and radio.

            Advertising isn't  the only way tobacco companies have tried to market their products. Candy-flavor^

cigarettes were once common. They contained tone (有毒的) chemicals and were as dangerous and addictive as regular cigarettes. Studies showed that these products were especially popular among teen smokers. And many teens mistakenly believed that these sweet cigarettes were safer than unflavored cigarettes. In 2009,flavored cigarettes were banned in the U.S..

            By now,maybe you,ve noticed a pattern: Each time new laws are passed to protect teens,tobacco companies come up with new methods. Many states have approved high taxes on cigarettes; and prices have been increased to reduce smoking. To deal with this,tobacco companies give discounts to convenience stores so they can charge less for cigarettes.

            The fact is that tobacco companies need you to become addicted to a deadly habit. Without new smokers,they will eventually go out of business. But you can at least make sure of one thing: They won't get you.

   A. smoking is still a problem among teenagers

   C. there are more teen smokers in the U.S. than other countries

7. Compared with regular cigarettes,candy-flavored cigarettes were.

                            ★★★

          A study conducted in the Svalbard Archipelago of;Norway showed the first recorded case of polar bears seeking out white-beaked dolphins(白喙斑纹海豚) for prey(猎物) . Warming waters have allowed the dolphins to travel north to an area they would normally avoid until summertime. “It is likely that new species are appearing in the diet of polar bears due to climate change because new species are finding their way north,” study author Jon Aars said.

          Arctic waters have warmed at a rate twice that of southern waters,putting the ice-loving bears in trouble. Polar bears typically sit on large pieces of ice to hunt swimming seals,but without the platform of ice to sit on,the bears have to look elsewhere for food. Two ice-free winters attracted the dolphins into the Arctic region,where their food has also shown up thanks to warm water. But a sudden influx (汇集)of ice trapped the dolphins,making them easy prey for hungry plar bears.

          The scientists from the Norwegian Polar Institute first discovered this eating habit in April,2014 and documented another five cases in the following year. Most of the bears appeased well-fed,although one was visibly thin and found covering a dead dolphin with ice as a means to hide his food source from other animals —another strategy that scientists had not yet seen before.

         It' s unlikely that there are enough dolphins to feed the large population of polar bears. And as the bears were only able to hunt the dolphins because of a sudden storm,their consumption could be a fluke(使幸) .

         Polar bears living in Canada and Alaska have been found traveling north to live in the icy regions they need,but Svalbard is about as far north as it gets before the water becomes too deep to serve as a livable habitat,leaving the bears with nowhere else to go.

9. What does Jon Aars think is to blame for polar bears' eating dolphins?

   A. Loss of habitat:    B. No other prey.

   C. Warmer climate.      D. Shorter summertime.

10. What do we learn about today's  polar bears from Paragraph 2 ?

   A. They fmd it harder to hunt seals.

   B. They have more food than before.

   C. They face more competitors than before.

   D. They are troubled by a sudden influx of ice.

11. It is very rare for a polar bear to.

   A. appear well-fed

   B. get nothing to eat

   C. hide food from other animals

   D. share food with other polar bears

12. After polar bears reach Svalbard,they .

   A. get no dolphins to eat

   B. cannot go any further northward

   C. hardly want to go anywhere else

   D. make it a comfortable livable habitat

                                      A 

          Prashant Mandal shares a small house with his wife and four kids,and survives on less than $2 a day. Yet,despite Mandal' s  modest income,he spends 20 percent of his income on solar energy,an expenditure (支出) which he says is key to helping his children to study.

          Across the globe,about 1. 2  billion people live without electricity. Such limitations are not only inconvenient,but also put people in low-income countries at greater risk of having serious health conditions. People living without electricity typically rely on kerosene lamps,and other harmful light sources,which can lead to bums,injuries,poisoning and other risks.

          Realizing the need for a more efficient energy source,a lot of companies have developed business models that enable poor people to purchase solar energy.

          SimpaNetworks,which focuses its efforts on rural India,is one such company that's found a way to make solar energy affordable and accessible to people in need. Customers are charged a small down payment for a high-quality solar system. Then,through its “progressive purchase^ model,they pay in advance for a designated (指定的) amount of energy consumption. Each payment counts toward the final purchase price.

          A number of other companies have found ways to get solar energy into the hands,anci homes of people who typically can’t  afford electricity. MPOWER D. a New ork-based company,invented an (充气式的) solar light in 2012 that is powered by the sun,and is also able to store solar energy.

          “Energy poverty is solvable if we all work together,” says John Salzinger,MPOWERD’s  co-founder. “Every single consumer purchase helps us reduce costs,and then we pass those savings on to those who need affordable light most. We automatically enable our customers to help others,while helping the environment,by simply making a purchase."

  1. Why does the author mention Prashant Mandal in Paragraph 1 ?

   A. To show that electricity is precioub.

   B. To bring up the topic of the text.

diseases. 

   D. People living without electricity may face serious risks.

   C. how customers use electricity in rural India 

   D. how solar system works in rural India 

4. How does John Salzinger feel about energy poverty?

                          ★ ★ ★ ☆ ☆

        (I wrote a letter to the future of me recently. And here is the letter.)

Dear Taylor,

        First of all,let's get this straight: I would much rather visit you in person,but I have yet to discover time travel. Seriously,though,I have some things to say to you.

I do think you would be somewhat shocked at how far you’ve come since the beginning of high school. Like,guess what? You’ve stopppd wearing makeup and straightening your hair to impress people. You have better things to do (like sleep) . Also,you haven’t lost all your weight,but you’ve gained the self-confidence you've been missing for a very long time.

        You’re probably not looking for advice because you want to be able to do everything on your own,but I'm going to tell you a few things anyway.

        ● Don’t apologize for your opinion* In fact,stop apologizing for so many things. It's unfair to yourself.

        ● Forgiveness is good,but you are not a doormat. Don’t be afraid not to let someone back in.

        ● Tell your grandparents you love them all the time.

        ● Put down that salad and pick up the cheeseburger. You hate salad,and you know it.

        You should also know that you will lose parts of yourself. You will stop believing in lots of things,people,and ideas,but vou are still left whole. You are still you- even more so.

         But,sadly,the world is going to let you down a lot. You are going to see awful things happen on the news,and you’ re going to feel frustrated because you can't do anything. However,the most important thing that you will come to realize is that your voice matters. You,just like everyone else,have some amazing things to say.

         Lastly,I want to tell you I love you,and I believe in you.                                                            Love,

                                                            YOU
