At about 4 am, after hours of being unable to sleep, of shivering in the cold mountain air and trying to silence my crying kids who kept waking up, of attempting to find a comfortable sleeping position, of listening to whether there might have been a bear outside our tent, I finally couldn't stand it any more. I complained, "Everything has gone wrong." My wife and I were in one tent with our two young kids. A hundred yards east away was Summit Lake, where the glorious early morning mist was shimmering off the water. A couple miles to the southwest was the base of the Lassen Peak Trail. The base was 8,000 feet above sea level, and huge snow dotted the scenery even in mid August. Further west still was Bumpass Hell, with steam rising up. As the sun crept up over the edge of the Lassen peak, we fired up the camp stove and had breakfast. Half an hour later, my six-year-old daughter and I were in the parking lot of the Lassen peak trail, getting ready to go up the mountainside. We wouldn't make it all the way, but it didn't matter. We would see nature at its extremes: the volcanic ash that layered on the earth turning the melting snow a mysterious pink as the sun struck it; the blues of the sky shading into the blues of distant lakes, which in turn shaded into the whites and grays of the snow. My daughter grabbed my camera. She wanted to take a photo of "the composite "of _ . Looking out over that scenery, and seeing my daughter fascinated by nature, I felt stupid about my morning complaints. Yes, camping is uncomfortable. And yes, there's a lot to be said for getting out a credit card,reserving a room in a nice hotel, and going out for a fancy meal. But there's also something wonderful about being so close to raw nature. And , as important, there's something vital about getting young children out of their increasingly modern comfort zones and forcing them to meet the world around them. .Which of the following statements can be inferred from the passage ? A) Nature is the glass reflecting truth. B) Nature is the best scenery designer. C) The journey of a thousand miles starts with one step. D) A bad beginning makes a bad ending.

Bicycle lights may not exactly be a problem that needs solving, but the following can be said about most of them ---- they're easily stolen if left on an unattended bike. People riding at dusk can forget to turn them on, and those same people can forget to turn them off when they reach their destination. Well, the makers of the Blink/ Steady Bike Light have set out to address all of those shortcomings. The waterproof Blink/ Steady is so far only available as a tail light, although a head light is on the way. It's fixed onto the bike's seat post. A built- in photosensor tells when it's become dark enough for the light to be required, and allows it to come on once you begin the riding. According to the producers, it isn't fooled by things such as headlights or streetlights. The light also contains an accelerometer, also known as a motion sensor, which can tell when the bike is in motion. Between the two sensors, this means the light will come on only once it's dark enough, and the bike is moving. Even when stopped at red lights, the small movements of the rider will reportedly be enough to keep the light activated---- it'll go out after 30 seconds of complete inactivity. While this does mean that the two sensors are continuously powered up, they go into a very low---- power sleep pattern when the bike is sitting, unused. Light is provided by two5- watt LEDs, seeable over a range of 180 degrees. And power comes from two AAA batteries, which provided up to 200 hours of continuous run time. The designers and engineers behind the Blink/ Steady are now raising money for its commercial production. About US $95 will get you one if they become available. According to the text, the Blink/Steady Bike Light is sensitive to _ . A) the weather B) streetlights C) headlights D) natural light

Q: Daniel Hillel developed drip irrigation techniques. The techniques make farming possible in places where there is not enough water. Because of this, he won this year's World Food Prize. Hillel is using the techniques in his orchards near his home in Israel. Irrigating drop by drop -- called drip irrigation -- has changed agriculture by greatly reducing the amount of water needed. Farmers now rely on it in places from Spain, to Africa, to America. "We in California grow about 50 percent of the fruits and vegetables of the continental United States," says Jan Hopmans from University of California at Davis. "And these drip irrigation techniques make it possible." Hillel got his start in dry land farming in Israel's Negev Desert in the 1950s. "The key was making good use of water," he says. "There's much land. Water is limited." These farmers did not have the advantage of running irrigation water through channels to their crops. So Hillel and others gave plants just what they needed and just where they needed it. "The idea is to use water little by little," Hillel says. It worked so well that Hillel was soon traveling around the world, showing others how to do it. Experts say drip irrigation's importance is growing, as climate change and rising population make water supplies become few in many parts of the world. "This is where water use, climate change and crop production all meet at one point," Hillel says. "And this has been really the essence of my career." A career whose importance can be measured drop by drop. What makes drip irrigation seem increasingly important? A) Dry land farming. B) Environmental pollution. C) Food shortages. D) Water shortages.
