    In a national survey, just 1 in 3 students thought that smoking on some days, but not others, can cause a lot of harm. This smoking pattern is common. It is also dangerous. In fact, its health risks are about the same as smoking heavily, report Stephen Amrock and Michael Weitzman. Their new study’s findings show that most kids do not see risks in smoking the occasional (偶尔的) cigarette.

For their study, Amrock and Weitzman analyzed data from the 2012 National Youth Tobacco Survey. It had probed (探究) tobacco-related knowledge, attitudes and behaviors in 24,658 students. All were in grades 6 through 12 and lived throughout the 50 U. S. states and the district of Columbia.

Most teens knew that heavy smoking can be harmful. About 2 in every 3 students recognized that smoking even just a few cigarettes each day can be harmful (有危害的). Only 1 in3 students, however, recognized that occasional—non-daily—smoking is harmful. Among teens who smoke this way—intermittently—just 1 out of every 7 understood their habit was dangerous.

Occasional smoking is not safe, so “we really need to have a conversation” with whoever thinks otherwise, notes Dave Dobbins. He heads research and public education at Legacy, a group based in Washington, D. C. It encourages teens to reject tobacco. “Intermittent smoking carries lots of risks,” Dobbins explains. These include the chance that light use will progress to heavier smoking. “We explain to kids that light smoking is smoking,” says Dobbins, who was not connected with the study. And, he adds, his group points out that “the dangers begin right away”.

Adults who are light or intermittent smokers are those most willing and able to quit. Amrock and Weitzman note. Most smokers start by age 18. That’s why the NYU School of Medicine researchers suggest anti-smoking efforts should target youth who today are light or occasional smokers.

1.What’s the text mainly about?

A.Occasional smoking. B.Health and smoking.

C.The number of smokers. D.Anti-smoking efforts.

2.Where can you find the data showing students’ views on different smoking patterns?

A.In Paragraph 1. B.In Paragraph 3.

C.In Paragraph 2. D.In Paragraph 4.

3.What’s the meaning of the underlined “intermittently” in Paragraph 3?

A.Heavily. B.Continuously.

C.Occasionally. D.Purposefully.

4.Dave Dobbins agrees that ________.

A.dangers of kids’ light smoking appear in no time

B.light smoking is sure to result in heavy smoking

C.most teens have realized the risks of light smoking

D.light smokers are likely to quit smoking naturally

 

1.A 2.B 3.C 4.A 【解析】 这是一篇说明文。短文通过研究证明,轻度或偶尔吸烟对青少年的健康是有危害的,研究者呼吁多关注轻度或偶尔吸烟者。 1.主旨大意题。根据第一段In a national survey, just 1 in 3 students thought that smoking on some days, but not others, can cause a lot of harm. This smoking pattern is common. It is also dangerous. In fact, its health risks are about the same as smoking heavily可知,一项全国性的调查中,只有三分之一的学生认为偶尔吸烟会造成很大的危害。这种吸烟方式很常见但是也很危险。事实上,偶尔吸烟所带来的健康风险与大量吸烟所带来的健康风险差不多。接下来文章对此展开了讲述,所以文章主要讲的是偶尔吸烟。故选A项。 2.细节理解题。根据第三段About 2 in every 3 students recognized that smoking even just a few cigarettes each day can be harmful (有危害的). Only 1 in 3 students, however, recognized that occasional—non-daily—smoking is harmful.可知,大约三分之二的学生认识到每天只吸几支烟是有害的。然而,只有三分之一的学生认识到偶尔——非每日——吸烟有害健康。所以在第三段可以找到显示学生对不同吸烟模式看法的数据。故选B项。 3.词义猜测题。根据第三段 Only 1 in3 students, however, recognized that occasional—non-daily—smoking is harmful.可知,只有三分之一的学生认识到偶尔——非每日——吸烟有害健康。划线单词是对this way的解释,this way代指的是上一句的 occasional--non-daily--smoking。由此可知划线单词的意思是“偶尔地”。所以在偶尔吸烟的青少年中,只有1 / 7的人明白他们的习惯是危险的。所以通过上下文可以判断出,划线词的意思是“偶尔地”。故选C项。 4.推理判断题。根据第四段We explain to kids that light smoking is smoking,” says Dobbins, who was not connected with the study. And, he adds, his group points out that “the dangers begin right away”.可知,我们向孩子们解释,轻度吸烟就是吸烟”多宾斯说,他没有参与这项研究。他补充道,他的团队指出“轻度吸烟的危害很快会显现”。由此判断出戴夫·多宾斯同意儿童轻度吸烟的危害很快就会显现。故选A项。

    Constantin Levaditi was born in Galati, Romania in 1874. His family was poor and his father was a Greek immigrant who worked in the Galati port and his mother was Romanian. When he was only six years old he had to start working in a shop as both of his parents fell ill. His job was to deliver orders from his uncle’s shop.

After two years his parents died and he was taken into care by one of his relatives who worked as a nurse in a hospital. His relative noticed that he was very smart and sent him to school.

Fuerteventura, Spain

Fuerteventura is a great place awaiting your discovery. Here are some reasons.

La Concha beach

Located in northeastern Fuerteventura are a number of family-friendly beaches. One of the most popular is La Concha, which is dressed in white sand and beautified with calm water. The beach is close to the town and at sunset, most tourists rush to see the skies turn beautiful colours in just a few short moments. At low tide (潮汐), small pools of water form, and these are great for the little members of the family to take a dive in. There are enough parking lots and plenty of restaurants to choose from.

Corralejo Natural Park

If you are looking to experience the desert nature of Fuerteventura, Corralejo Natural Park is the place to be. It is a coin with two sides. One is characterized by volcanic scenery, and the other is white sand that has been cleansed by the blue water of the Atlantic Ocean. Getting to the park can be easily done by road, but exploring it demands that you put on your hiking shoes and take a walk through the natural wonderland.

Costa Calma Beach

Costa Calma Beach is characterized by blue waters and white sand. The beach is not packed, so you will get a chance to be just with your thoughts as you sunbathe on the sand. When the winds are swift, Costa Calma turns into a hot spot for surfers, ideal for those looking to get a surfing course. The road leading to the beach is fenced by green plants meaning the magic starts even before you get there.

Cofete Beach

It’s hard to find a fitting description for this wild beach. Its shoreline is great for its golden sand and wild water. Getting to Cofete Beach is not easy: perhaps that’s why this place is still in its original state. The road has difficult spots that require expert driving skills. But, if you can tolerate it, you will be treated with some amazing views.

My name is John and I must share with you an event which took place on Flight 1553 out of DCA. My wife and I were traveling to Miami to celebrate an achievement for her and as you can imagine, we were looking forward to fun, sun and laughter.

We boarded the aircraft, without a care in the world. It was cold in Washington and we were ready for Florida. Shortly after taking my seat, I began to feel sick. I knew something wasn't right but just couldn't find out what was happening .Being a doctor and a stubborn man, I resisted efforts by my wife to call for assistance. As the aircraft began its departure roll, I lost consciousness for a short amount of time. As I came around, I quickly realized a few things. Firstly, something very bad had happened to me .Secondly, the aircraft was too heavy with the fuel to go back home. Thirdly, my loss of consciousness had been so deep that I found myself out of control. So not only did I have a medical issue to deal with, but I also had to figure out how to deal with an embarrassing experience.

My wife gathered the crew as soon as it was safe to move about and I made my way to the washroom to attempt to clean up. I did my best and the flight crew members were so supportive,

checking on me often and reassuring me that there was nothing to be embarrassed about. It was their sympathy and support that helped me so much. During the flight they kept watching over me and I suddenly had a small group of nurse, bringing blankets, food, drinks and caring and smile. I was thankful to them.
