All bats fly at night and most of them hunt for flying insects(昆虫), such as bees. The common bat finds its food by
making a constant noise that the human ear cannot 
hear. The bat listens for echoes(回声) of the noise as it bounces(反射) off the insects showing the bat their position.The Fruit bat feeds on many different kinds of fruit. It does not use echoes but instead has very large, special eyes to see even in low light. The largest Fruit bat has a wing length of 0.75 meters. The Vampire bat drinks the blood of large mammals, and a few bats catch fish, birds and even other bats.

The first step in finding out about Indian Creek is to request an information packet. We will be happy to send you a packet containing a brochure(小册子), the fee structure and an application. The packet should answer most of your general questions about the school.
In order to get a true sense of Indian Creek School, you should come for an Admission Tour, which includes a personal meeting focusing on your child, a tour of the building and the classrooms, and a discussion of the curriculum(课程).
This visit is no less important if the child for whom you are seeking admission is a teenager than if he or she is a three-year-old one. Every school has a different “school climate.” If you visit two or three schools, you will notice that each “feels” different. You know your child best and you will quickly develop a sense of whether a school is the right match or not.
●The initial point of entry for Indian Creek Students is at the pre-kindergarten level for three year olds.
●Children must be three years old by August 31st.
●We also have major points of entry from grade six to grade nine. At each of these levels, we open new sections and accept students in addition to those moving up from our own lower grades.
●There are scattered(零散的) openings available throughout the program due to attrition(学生流失). Once an opening occurs, students spend a day at ICS, part of which includes admission testing.
小题1: You can NOT get to know about ICS by ________.
| A．getting an information packet |

Houston was surprised by their studies that suggested that communication can be a powerful tool in medicine. They showed that those who had had similar experiences, when talking to someone with a similar background, could help change their behavior to become healthier. Hypertension is difficult to control, since it is dependent on diet, exercise and mental state. Medical treatments with drugs, and lifestyle therapies(疗法) have been relatively ineffective because people find it hard to follow those medical requirements.
In the test, his team carefully chose their story-tellers from 23
0 members of a patients" community with whom they could most easily relate. Next, they divided their study population into two groups. One received three interactive DVDs containing the tellers" stories of their experiences in living with and treating their hypertension. The other were given educational discs on an unrelated health topic. The study volunteers reported that they had listened to the DVDs, and after three months, those who heard the stories of the hypertensive patients lowered their blood pressure.While the study did not address how the story-telling influenced the patients" behavior, Houston doubts that watching patients of similar backgrounds who had a similar medical experience helped to motivate them to seek medical help to their hypertension. They found that after six months the difference in blood pressure between those who watched the story-tellers and those who observed the unrelated videos remained, suggesting that the story-telling continued to have an effect.
小题1: We can learn from the text that the pre-recorded videos _________.
| A．tell medical histories of hypertension patients |
| B．introduce some medical treatments of hypertension |
| C．introduce a good lifestyle for hypertensive patients |
| D．tell scientific discoveries of the scientist group |
| A．hypertension is really difficult to control |
| B．communication has some medical effects |
| C．medical treatments have no effect at all |
| D．people don"t follow the medical requirements |
| A．persuade | B．observe | C．attend | D．announce |
| A．The stories of some hypertension patients. |
| B．Medical treatments of blood pressure. |
| C．Storytelling may help lower blood pressure. |
| D．Suggestions about how to lower blood pressure. |
A high school history teacher once told us, “If you make one close friend in school, you will be most fortunate. A 21 friend is someone who stays with you for life”. 22 teaches that he was right. Good friendship is just not easily 23 .
It is possible that we simply do not stay in one place 24 enough for true
friendship to develop. However, there can be 25 disagreement on the need for each of us to think carefully about the kind of friendship we want.
To most of us, friendships are considered very important, 26 we need to
have it clear in our minds the kinds of friendship we want. Are they to be close or 27 at arm’s length? Do we want to 28 ourselves or do we want to walk on the surface? For some people, many friendships on the surface are 29 enough. And that’s all right. But at some 30 we need to make sure that our expectations are the same as our friends’ expectations. The sharing of personal experience including our tears as well as our dark 31 is the surest way to deepen friendships. But it must 32 slowly and carried on only if there are 33 of interest and action in return.
What are some of the 34 of our friendship? The greatest is to 35 too
much too soon. Deep relationships 36 time. Another “major difficulty” is the selfishness to think one “possesses” the other, including his time and attention. 37 , friendships require actions in return. In other words, you must 38 as much as you take. Finally there is a question of taking care of. Unless you spend 39 time together, talking on the phone, writing letters, doing things together, friendships will die 40 .

Teenagers learn by closely observing what people around them do. Parents are literally their first teachers and serve as role models. From hygiene to habits, from time management to personal manner, parents form the foundation of their children"s characteristics. These tiny individual factors on our everyday behavior collectively constitute who we are.
A second influence occurs at the spiritual level. Parental treatment of children is reflected in children"s relationship with others. For example, my dad was quite angry with my study habits a few years back and lost his temper.I clearly remember that I too would easily lose my cool and shout at people, often saying things I later regretted, in those difficult days.
Parents of my fellow classmates often tend to be anxious about the studies of their children, which can lead to a lack of confidence in their children. If we are boats weathering a storm as we navigate toward maturity, then parents should be our captains. It is as easy to lead us to shipwreck as is to take us ashore safely.
To be fair, the guidance and influence of our parents are not the sole factors in molding us. There are numerous examples of teens forging their own paths and becoming something of which their parents never dreamed. Even so, parents must be a fundamental force that positively influences their children. At their best, they can help to solve teenage problems with a respect for their children"s thoughts.

The first caves appear as seven mysterious black dots （点） on the pictures which were sent back by NASA’s Mars Odyssey orbiter. Each as large as a football field, they may be openings into natural caves below the Martian surface.
“If there is life on Mars, there is a good chance that you’d find it in caves,” said Jut Wynne, one of the researchers who noticed th
e features (特征) while working on a US Geological Survey Mars Cave Detection Program. Jonathan Clarke, a geologist with the Mars Society of Australia, yesterday described the discovery as exciting.
One photo taken at night by an infrared imager(红外线成像器) showed one hole to be unusually warm, suggesting hot air may be flowing out.
“I said: ‘Wow, that’s a cave’” Dr. Clarke said excitedly. “People have been looking for these for a long time; now we have found them.”
He agreed such caves could be perfect places to search for life escaping from the bitterly cold, radiation-soaked(充满辐射的), dry surface.
“Tiny drops of water could collect inside,” he said. “If there are gases coming out, they could provide energy for a whole range of bacteria (细菌). A cave is also a protection from radiation; the surface of Mars is exposed to high levels of space radiation.”
The caves probably formed when tube-shaped lava flows(管状岩浆流) spread across the planet long ago. The outside of the tubes cooled, forming solid walls, while something hotter inside allowed the remaining to flow out, forming caves.
小题1: What does the passage mainly talk about?
| A．How the caves were formed on Mars. |
| B．How NASA sent the pictures back to earth |
| C．Caves on Mars may be full of hot air or a sign（迹象）of life. |
| D．Scientists have completely recognized the surface of Mars. |
| A．water has already been found on Mars |
| B．the scientists found all the caves at night |
| C．it is certain that there is life in these caves |
| D．the surface of Mars is bitterly cold, radiation-soaked and dry |
A．such caves could provide energy for life |
| B．they had finally found the caves on Mars |
| C．such caves would be perfect places to search for life |
| D．There would be life on Mars. |
| A．lava and energy | B．water and radiation from space |
| C．gases and lava | D．water and protection from radiation |
| A．the Mars | B．the earth | C．the caves | D．radiation |
