Ques:We invite you to our GoNeutral Walk, formerly known as "Walk for Water" * Saturday April 13, 2013 * From 8:30 am -- 3:30 pm Paramount Ranch  , Agoura Hills We invite you and your friends to join Jewish National Fund for our Walk to help the environment! We must take responsibility for the Earth's future. You can help offset   our carbon emissions   by planting trees and contributing to Jewish National Fund's important environmental work in the event.  Please feel free to contact: Donna Daniel at ddaniel@jnf.org or (818) 704-5454 x201.  We look forward to seeing you there!  Each year we host a Walk event, which is a huge success, attracting over 2,000 people from around the Los Angeles area. This year, the Walk has a new look. JNF partnered with the new green plan, GoNeutral. The GoNeutral campaign is focused on removing our carbon footprints from the Earth and contributing to a healthier future for our planet. Funds from the GoNeutral Walk will go towards JNF environmental programs to stop desertification  , promote water reuse, grow crops efficiently in the desert and create green "lungs" around cities. This is an exciting and unique opportunity for you to support a very important effort, as well as enjoy a fun day filled with live entertainment, children's activities and much more at the park. Thank you for your support and I look forward to your commitment to the GoNeutral Walk this year. For more information visit www.jnf.org/goneutral or www.walkforwater.org or www.jnf.org. Feel free to contact us at (818) 704-5454. A person who wants to take part in the activity   _  .

Ques:Every girl wants to have a great-looking tattoo   design that makes them more attractive. Small and lovely tattoo designs are the path to go for girls planning to get tattooed for the first time. Nowadays, more and more females are getting a tattoo inked on their body. In the last fifteen years, tattoos have grown from being a sign of rebelliousness and trouble to a state of popular acceptance as a mark of fashion. Tattoos are permanent so you need to be sure that you like it before getting one. A great way is to have small tattoos that look beautiful as well. You can get a cherry blossom tattoo on the foot, perhaps, a hibiscus flower on the shoulder or a lovely butterfly on the lower stomach; whatever design you choose, it can definitely add to your attractiveness and charm. Deciding to get a tattoo needs careful thought and reflection. Otherwise, you could make some serious tattoo mistakes. Try to avoid big and obvious designs if possible. Another important part of choosing a tattoo design is the location. What part of the body do you want it on? Choosing a hidden location can often make the tattoo the perfect adornment  . As for professional women, tattoos should normally be where they can be hidden. Most importantly, no matter what tattoo design you choose the final goal is that the design should be something you like. If you are into the tattoo and really feel passionate about it you will carry yourself in a different manner when you get it inked on your body. What is the author's attitude towards girls' getting a tattoo? A) He is against girls' doing so B) He thinks professional women should not get tattooed C) He is in favor of it as long as it is done probably D) He calls on all the girls to do so

Ques:"Plants were expected to get larger with increased carbon dioxide in the atmosphere, but changes in temperature, humidity and nutrient availability seem to have _ the benefits of increased carbon dioxide," said researchers from the National University of Singapore. 45 percent of the species studied now reach smaller adult sizes than they did in the past. The researchers point out that warmer temperatures and changing habitats, caused by climate change, are possible reasons for the shrinking of creatures. "We do not yet know the exact mechanisms involved, or why some organisms are getting smaller while others are unaffected," the researchers said. "Until we understand more, we could be risking negative consequences that we can't yet quantify." The change was big in cold-blooded animals. Only two decades of warmer temperatures were enough to make reptiles  smaller. An increase of only 1degC caused nearly a 10 percent increase in metabolism . Greater use of energy resulted in tiny tortoises and little lizards. Fish are smaller now too. Though overfishing has played a part in reducing numbers, experiments show that warmer temperatures also stop fish growth. There is a recent report on warmer temperatures' negative effects on plankton ,the base of the marine ecosystem. Warm-blooded animals weren't immune from the size change caused by climate change. Many birds are now smaller; Mammals have been miniaturized too. Soay sheep are thinner. Red deer are weaker. And polar bears are smaller, compared with historical records. This isn't the first time this has happened in Earth's history. 55 million years ago, a warming event similar to the current climate change caused bees, spiders and ants to shrink by 50 to 75 percent over several thousand years. That event happened over a longer time than the current climate change. The speed of modern climate change could mean organisms may not respond or adapt quickly enough, especially those with long generation times. So, it is likely that more negative influences of climate... Which of the following would be the best title for the passage? A) Why do some species become smaller? B) How does climate change in Earth's history? C) Climate change has many negative effects D) Species become smaller as climate warms

Ques:Astronauts aboard the space station celebrated a space first on Wednesday by drinking water that had been recycled from their urine , sweat and water got from air. They said "cheers," clicked drinking bags and toasted NASA workers on the ground. The urine recycling system is needed for astronaut stations on the moon and Mars. It also will have NASA money because it won't have to ship up as much water to the station by space shuttles or cargo rockets. Besides, it's important as the space station is about to expand from three people living on board to six. The recycling system had been brought up to the space station last November by space shuttles Endeavour, but it couldn't be used until samples  were tested back on earth. So when it came time to actually drink up, NASA made a big deal of it. The three-man crew stood holding their drinks and congratulated engineers in two NASA centres that worked on the system. "This is something that had been the stuff of science fiction," American astronaut Michael Barratt said before taking a small mouthful. "The taste is worth trying." The new system takes the combined urine of the crew from the toilet, moves it to a big tank, where the water is boiled off, and the vapor  is collected. The rest of the urine is thrown away. Then the water vapor is mixed with water from air, and then it goes through filters  . When six crew members are aboard it can make about six gallons from urine in about six hours. "Some people may find the idea of drinking recycled urine distasteful, but it is also done on earth, but with a lot longer time between urine and the tap," said Marybeth Edeen, the space station's national lab manager. The technology NASA developed for this system has already been used for quick water purification after the 2004 Asian tsunami. What did Edeen say about recycled urine and the recycling system? A) The taste of recycled urine is not as good as that of common water. B) The recycling system has made a science fiction story come true. C) The idea of drinking recycled urine makes astronauts feel unpleasant. D) It takes a longer time on earth to make water from urine than in space.
