Targeting teens Using the web makes teens a target. Posting too much personal information for those millions of cyber eyes to see can cause some big problems and can even invite a threat to your life. As Mary learned, not everyone on the Internet is who he or she says they are. Adults will sometimes pose as other teens, posting fake photos and nice messages to gain trust. They use their fake identity to access the personal information of others, such as home address, phone number, or school name. "That's not the most common scenario ," says David Finkelhor, a sociology professor at the University of New Hampshire. "Only 3 percent of teens aged 10 to 18 who use the Internet report being asked to meet offline. But the danger is real." Safety measures Mary's Myspace profile is set to "private", which means that only the people she adds under the "friend" category can access her page.

It is winter in many parts of the world. For some areas, that means snow. Maybe even lots of snow. If you don't have to drive in it or remove it, snow can be very beautiful. When snow covers everything around you, the world looks like a "winter wonderland". That is the name of a very popular song about winter. Richard Smith and Felix Bernard wrote the song back in 1934. There are hundreds of recordings of this happy song. But winter is not always such a beautiful and happy time. It's cold outside. You try hard to keep warm. The days are darker and shorter. The sun rarely shines. The leaves on the trees are brown. It isn't surprising that some people are sad in winter. And some people dream about being somewhere else where it's warm and pretty--like the state of California. The Mamas and the Papas recorded this famous song "California Dreaming". During the 1960s, many other famous rock groups released songs about winter. Here is a poetic song by Simon and Garfunkel called "A Hazy Shade of Winter". They sing about life and hope and possibilities. In 1968, the group Blood, Sweat and Tears recorded this gentle, sad song about winter. They sing about a lost love and forgotten memories in "Sometimes in Winter". In the early 1990s, Tori Amos wrote and recorded the beautiful song called "Winter". She enjoyed singing about winter when she was a child. Finally, on a happier note comes this song written and recorded by Fountains of Wayne in 2003. They sing about a snowstorm in a New England town. Nothing unusual there. But instead of being sad or tense about the snow, they write a song about it. What does the passage mainly talk about? A) Songs about winter. B) Different ideas about winter. C) Winter in different areas. D) Winter is cold but happy.

Frank Sinatra sings it. It is a feeling of restlessness or excitement brought on by the coming of spring. Richard Rodgers also wrote Spring Is Here, this time with Lorenz Hart.

Because the singer's lover has left her. Sarah Vaughn released her version of the song in 1953. By now you may be thinking, "Enough with the sad songs, already!" Ok, then how about a cowboy song?

Ques:Several years ago, the mayor of Chicago, Illinois, visited Germany, a leader in green roof design. Later he decided to have vegetation planted on Chicago City Hall. Today, the tops of many other buildings also look like parks. In Canada, the Coast Plaza Hotel in Vancouver has a forest on its roof. New York City has an unusual example farm for hydroponics. The farm is on a boat called the Science Barge. Rainwater and river water are used to grow lettuce, tomatoes, cucumbers and peppers. The farm shows the possibilities for designing rooftop systems. Green roofs are designed to save energy and capture rainwater. Rooftops covered with plants help keep buildings cool. They can extend the life of a roof. And they can reduce water running off into streets and storming water systems. Experts say green roofs usually do not get much above 27degC. So temperatures might not be a problem for growing. But rooftop gardeners have to be careful not to put too much weight on the roof. This is true whether plants are grown in soil or water. Earlier in 2008, researchers in Texas reported that green roofs can reduce a building's air conditioning costs by about onefifth compared to blacktop roofs. But they also reported that not all green roofs perform equally well. They found that designs differ in their ability to keep buildings cool and to capture rainwater. The researchers put experimental roofs on top of metal insulated boxes, to recreate green roof conditions. The study compared products from six companies to help businesses understand how to improve their designs. Each rooftop had sixteen different kinds of plants native to Texas. The researchers say the presence of native plants likely helped all the green roofs capture water better compared to sedums. Sedums are plants that need little water and often are used on green roofs. The native plants could take in more water and release more of it to the atmosphere. According to the passage, which conclusion is WRONG? A) Sometimes green roofs may break down the house. B) Not all the green roofs can reduce the building's air conditioning costs equally. C) Different designs of green roofs have different effects on buildings. D) Sedums are a kind of plants native to Texas.
