Millions of people visit Yosemite National Park every year to see the tall waterfalls and mountains. The mountains are a splendid sight when viewed from the valley floor. Lots of stores, hotels, and restaurants are needed to handle the crowds. Also, water, roads, and other service systems are part of the infrastructure(基础设施)that must be maintained.
Unfortunately, these systems are starting to break down. It’s not just in Yosemite but in national parks around the nation.
Yosemite is thirty years old according to Dennis Galvin, a National Park Service worker. The park is not only old but worn out. Two or three times as many visitors come every year. That is too many visitors for the park to deal with.
Four years ago a storm washed out a water pipeline in the Grand Canyon. The National Park service had to send water trucks to provide water for the visitors. Last month pipes almost broke again and roads had to be closed for a while.
Why hasn’t the National Park Service kept up the park repairs? There is a lack of money. The United States has 378 monuments, parks, and wilderness areas. Between three and four billion dollars are needed for repairs.
Yosemite is one national park that does have money for repairs. It has two hundred million dollars but cannot spend it any way it chooses. When the park workers started widening the road, they were forced to stop by the Sierra Club. The club claimed that the road work was damaging the Merced River that runs through the park.
A Sierra Club lawyer, Julia Olson, feels that the infrastructure needs to be moved out of Yosemite. That way less pressure will be put on the already crowded park.

I travel a lot in my work, and what I dislike about
my job is eating alone. It always makes me feel lonely to see others laughing and talking. So, room service for several nights was a better choice for me.
After having room service three nights at a hotel in Houston, however, I needed to get out of my room. Although the restaurant opened at 6:30, I arrived at 6:25. The waiter at the front desk made a comment(评论) about my “being there really early”. I explained my dislike of eating alone in restaurants. He then seated me at a lovely table and asked me whether I would mind if he sat down with me for a while.
I was glad! He sat and talked with me about his career goals and the difficulty of being at work on nights, weekends and holidays. He said he hadn’t enough time to be with his family. After 15 minutes, he saw some customers at the front desk and excused himself. I noticed that before he went to the front desk, he stopped in the kitchen for a moment.
Then another waiter came out of the kitchen and had a wonderful chat with me. Before I left that night, some other waiters, even the cook, had come out of the kitchen and sat with me! When I asked for my bill about one hour later, all the people who had sat down with me came over in a big group to my table, and presented me with a red rose. And I cried! What had begun as a lonely night ended as a beautif
ul experience.

Ears are for hearing — everyone knows that. But for a creature called the Cuvier’s beaked whale, hearing starts in the throat (喉咙), a new study found.
The observation might help explain how all whales hear. The work might also help scientists understand how animals ar
e affected by underwater sonar (声呐). This sonar, used by some ships, sends out sound waves to locate underwater objects.
The Cuvier’s beaked whale is a so-called toothed whale. Toothed whales dive deep into the ocean in search of food. As the whales hunt, they produce sounds that reach objects and then return to the whales. This allows the animals to “see” the shape, size, and location of objects, even when they’re 1,000 meters under the sea, where it is totally dark.
To better understand how the whale hears, researchers from San Diego State University in California took X rays of two Cuvier’s beaked whales. The whales had died and washed up on the beach.
Ted Cranford and his colleagues used the images to make a computer model of a Cuvier’s beaked whale’s head. Then, they modeled the process of sound traveling through the head.
The researchers knew that some sounds get to the ears of a toothed whale through a structure (构造) called “the window for sound”. Found on the lower jaw, this structure is very thin on the outside and has a large pad (垫) of fat on the inside.
When the researchers used their computer model to work out how sound waves travel in the whale’s head, they were surprised to find that sounds coming from right in front of the whale actually travel under the animal’s jaw. From there, sound waves move through the throat, into a hole in the back of the jaw, and finally to the pad of fat near the animal’s ears.

| A．A hole in the back of the jaw → the ears → the jaw → the throat. |
| B． The jaw → the throat → a hole in the back of the jaw → the ears. |

| D．The researchers haven’t found how the whales hear. |
A young British sailor was missing at sea yesterday in similar circumstances(情况) to the way his father died five years ago．
The dinghy(救生橡皮船), used to take Richard Smith, 21, to his yacht(快艇), was discovered empty, floating in seas off the Caribbean island. An air and sea search was carried out but he has still not been discovered.
Richard’s mother, Bicknell, said from her home in Hampshire, “It’s so much coincidence(意外). Richard always carried a photograph of his father attached to a poem, which included the date of his disappearance.”
“Now, it’s very strange because all they have found is Richard’s dinghy. We need to know this time what has happened one way or another. If you know at least you can go through the grieving process(悲痛的过程).”
In November 1996, Mr. Smith’s father, Charlie, was sailing in the Tasmen sea between the Australian mainland and the island of Tasmen with his new wife. They lost radio contact with the s
hore and they, together with their yacht were never seen again, and their disappearance remains a mystery.
Richard is described as a talented and experienced sailor. He had sailed to the Caribbean in November to help a yacht race for entertainment. He ended the evening drinking in the Abracbabra bar but left after local police closed it for being too noisy.
About 2 am the following day Richard headed back for his dinghy. He started its motor before giving an elderly woman a lift to her yacht after her dinghy had gone missing. It was the last time he was seen.

I a
m trying to muster (鼓起) the courage to toss away my mobile phone to enjoy a more peaceful and ringfree life.
Can you imagine not having your mobile phone? In our hightech, inahurry age, a cellfree life is a hard concept to swallow. Our mobile phones can now access the Internet, and many people feel the need to express their every thought on their blog pages. If I gave up my cellphone, people would think I was mad.
I wish I had the strength to toss away my technology. I have an office phone, a home phone，an email and if people want to contact me, they can. If I’m out，people can leave a message. Do they really need to find me 24/7？However, I’m a bit like Frodo in the movie Lord of the Rings. The power of the ring is too strong and I can’t let it go.
Mobile phones have become necessary tools in our busy life. For most people, they hold all contacts and many of us don’t write up address books any more. The latest phones carry our music, pictures, movies and everything else. We feel lost without this device and when we do misplace it, we feel cut off from our fellow.
“Where have you been？” said a friend, who saw me a week after I lost my cellphone, “I tried calling you, but you disappeared. You disappeared off the face of the Earth.” See, when you don’t have a mobile phone, you don’t exist.
I’m not really going to toss my mobile phone away, in fact. We humans are such social animals and mobile phones serve us well. So in 2009, I’ve decided not to serve my mobile phone. Like all machines, I can always turn it off.
61. What does the underlined phrase “toss away” mean?
| A．give away | B．get away | C．break away | D．throw away |
62. The writer mentions Frodo to________.

| B．show how much he likes Frodo |
| C．suggest a cellfree life is what he wants |
| D．introduce a film character to us |
63. What do we know about mobile phones in the 4th paragraph?
| A．Mobile phones can do anything for us. |
| B．Mobile phones have become very important in our life. |
| C．We could not live without mobile phones. |
| D．We would be cut off by our fellow without mobile phones. |

| A．The writer is not really going to toss his mobile phone away. |
B．Whe n you don’t have a mobile phone，you don’t exist. |
| C．The writer decides not to serve his mobile phone. |
| D．We humans can control ourselves and machines. |
What color do you like best? Do you like yellow, orange and red? If you do, you must be an optimist, a leader, or an active person who enjoys life, people and excitement. Do you prefer grey and blue? Then you are probably quiet, shy and you would rather follow than lead. If you love green, you are likely to be strong-minded and determined. You wish to succeed and want other people to see you are successful. At least this is what psychologists （心理学家）tell us. They have been seriously studying the meaning of color preference, and the effects that colors have on human beings. They tell us that we don’t choose our favorite color as we grow up. If you happen to love brown, you do so as soon as you open your eyes, or at least as soon as you could see clearly.
Black is depressing while light and bright colors make people not only happier but more active. A yellow room makes us feel more cheerful and more comfortable than a dark green one does, and a red dress adds warmth and cheer to sad winter days. It is a fact that factory workers work better, harder and have fewer accidents when their machines are painted orange rather than black or dark grey.
Remember, then, that if you feel low, you can always brighten your day or your life with a few colorful things. Also remember that you will know your friends (and your enemies) better when you find out what colors they like and dislike. And don’t forget that anyone can guess a lot about you when you choose a piece of handkerchief.

| A．Because workers tend to prefer orange to other colors. |
| B．Because other colors are forbidden in factories. |
| C．Because less accidents happen due to the introduction of orange machines. |
| D．Because orange machines are easier to clean. |
69. Which of the following statements is Not true according to the passage?
| A．It’s possible to cheer you up by enjoying some colorful pictures. |
| B．You can know your friends better through the color they like or dislike. |
