A Plan For Exploring Mars
NASA is moving ahead with plans to put a long-armed lander on Mars’ icy north pole to search for
clues①for water and possible signs of life.
The $386 million Phoenix Mars is planned to touch down in the Martian arctic in 2008. The stationary probe will use its robotic arm to dig into the icy land and pick up soil samples② to analyze. In 2002, the Mars Odyssey orbiter spotted evidence of ice-rich soil near the arctic surface.
Scientists hope the Phoenix mission will find clues to the geologic history of water on the Red Planet and determine whether small living things existed in the ice.
Phoenix will be the first mission of the Mars Scout program, a renewed, low-cost effort to study the Red Planet. “The Phoenix mission explores new territory in the northern plains of Mars analogous to the permafrost regions on Earth,” Peter Smith said.
True to its name, Phoenix rose from the ashes of previous④ missions. The lander for Phoenix was built to fly as part of the 2001 Mars Surveyor program. But the program broke down after the well-known disappearance of the Mars Polar Lander in 1999. The Polar Lander lost contact during a landing attempt near the planet’s south pole after its rocket engine shut off ahead of time, causing the spacecraft to fall about 130 feet to almost certain destruction.
The Phoenix probe had been in storage at a Lockheed Martin clean room in Denver before it was reused for its present mission. It will carry science instruments that were designed for the Mars Surveyor program including an improved panoramic camera and a trench-digging robotic arm. Phoenix will lift off from the Kennedy Space Center in August 2007 and land on the planet nine months later. 64. The passage mainly tells readers that _________. A. clues of water will be found in Phoenix
B. Phoenix will be sent to find clues of water on Mars C. August 2007 will see Phoenix lift off D. the Mars Scout program will be carried out
65. According to the passage, we know Phoenix will land on Mars _________.
A. in May 2008 B. in August 2007 C. in August 2008 D. in September 2008
66. After Phoenix lands on Mars, we can infer it will firstly _________. A. find soil samples and send them to the earth B. look for the icy land to dig for the soil samples C. take photos and send them to the earth D. find the remains of the Mars Polar Lander
64. B 主旨大意题。文章的第一段就是该文章的主题句，由此可知文章要讲述的主要内容。 65. A 细节计算题。由文章最后一段最后一句可以计算出。
66. B 推理判断题。由文章的第二段可知，Phoenix的目的就是要通过挖掘冰地，取出样本进行研究。因
此，它首先要寻找冰地。

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 runoff into streets and storm water systems.
Several years ago, the mayor of Chicago, Illinois, visited Germany, a leader in green roof design. Mayor Richard Daley later 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.
Experts say green roofs usually do not get much above twenty-seven degrees Celsius. 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.
New York City has an unusual demonstration farm for hydroponics. The farm is on a boat called
the Science Barge. Rainwater and purified river water are used to grow lettuce, tomatoes, cucumbers and peppers. The farm shows the possibilities for designing rooftop systems.
Earlier this year, researchers in Texas reported that green roofs can reduce a building's air conditioning costs by about one-fifth compared to black-top 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.
Mark Simmons led the study for the Lady Bird Johnson Wildflower Center at the University of Texas at Austin. “Green roofs have to be done right,” he says. For example, he says, “Just having a green roof may not mean anything in terms of preventing water from reaching the street level.”
The team put experimental roofs on top of metal insulated boxes, to recreate green roof conditions. The study compared products from six companies. The researchers say they want 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, a kind of plants that are often used on green roofs but capture little water.
The native plants could take in more water and release more of it to the atmosphere.
67. According to the passage, which of the following is NOT right as the benefits of green roofs?
A. B. C. D. A. B. C. D.
Green roofs help keep buildings cool. Green roofs help save water and energy. Green roofs help protect the roofs of buildings.
Green roofs help reduce a building's air conditioning costs. there is much to be improved in present green roof design green roof is greatly needed nowadays
it is of great importance to take measures of saving energy
rooftop system may cause damage to the roof if improperly designed
68. By saying “Green roofs have to be done right”(in Para. 7), Simmons meant that ______.
69. Researchers in Texas found that ______.
A. Black-top roofs are as effective as green roofs in reducing a building's air conditioning costs B. D.
native plants hold more water than sedums
the farm on a boat was suitable to build a green rooftop system on it
C. metal insulated boxes are helpful in preventing water from reaching the street level 70. We can learn from the passage that ______.
A. Germany has already made great achievement in green roof design years before
B. one of the problems unsolved is that the temperatures might be unsuitable for rooftop
plants C. D.
67. 选B。从文章的第一段可知绿色屋顶\的各种好处，包括“吸收雨水”(capture rainwater)，
绿色屋顶的吸收雨水功能只能有助于保持房屋凉爽和节能，并不节水，故B选项说\既能节能也能节水\不是对\好处的正确表述，应为正确选项。 68. 选A。从文章第七段给出的\例子\可知答案。
buildings are often not strong enough to hold the weight of rooftop plants [来源:学*科*网sedums can hold as much water as the native plants in Texas
Z*X*X*K]
69. 选B。从文章最后两段可知，研究人员发现\当地植物吸水性能更好\。

Intense physical exercise is not the only way to better health. Studies show that walking several times a week can lower the risk of many diseases. They include heart disease, stroke, diabetes, bone loss, arthritis, and depression. Walking also can help you lose weight.
Fast walking is good for the heart. It lowers the blood pressure. It raises the amount of good cholesterol in the blood. Researchers say walking can sharply reduce the risk of suffering a heart attack.
Studies have also shown that walking for 30 minutes a day can delay and possibly prevent the development of diabetes. People who are overweight have an especially high risk to develop this disease.
Walking strengthens the muscles and builds up the bones that they are attached to. Studies show that walking could decrease the risk of developing osteoporosis. Walking can also help ease the pain of arthritis in areas where bones are joined. This is because walking strengthens the muscles around the bones.
Experts say walking is one of the safest ways to exercise. There is a low risk of injuries. So it is A walking program is easy to start. You should wear loose clothes and good shoes.
