All penguins (企鹅) swim in cold waters and so need a good layer of insulation (隔离), some species come ashore in hot places.Humboldt penguins,for example,nest in arid hot - 40°C, deserts on the west coast of South America, while others survive the lowest temperatures of any animals.Male Emperor penguins,as we know, spend the Antarctic winters incubating eggs in temperatures that can fall below -70°C. The insulation is provided in layers, under the skin is a thick layer of fat, then there is a layer of downy feathers that trap air, and finally another layer of waterproof feathers that keep the cold water away from the skin. With all this insulation penguins have no problem keeping warm at temperatures down to about -10°C - although they have special adaptations of the circulatory system to keep their feet from freezing and to prevent much heat loss through the feet that are on the ice. At lower temperatures penguins have to huddle (蜷缩) together to keep warm. In such huddles the penguins gradually move from the hot interior to the cold outside so that every penguin has his turn in the middle and on the outside.
In hot climates, penguins suffer greatly from overheating. They use several strategies to lose heat. They puff up their feathers so that air can circulate to their skin; they hold their flippers（脚蹼）out from their bodies and pump hot blood to them so that they can act as radiators; they open their mouths and breathe to lose heat from their hot breath; and those species that live in hot climates also have several bare patches of skin around the eyes and feet, they send blood to these bare patches when they are hot - you can recognize a hot penguin since it will have pink eye patches and pink patches on its feet.
77. Which of the following are the ways for penguins to keep warm?
a. staying together in good social order
b. several layers as radiators
c. a special circulatory system d. waterproof feathers
e. sending blood to bare patches
f. always staying in the middle
A. a, b, c B. a, c, d C. b, c, e D. c, d, f
78. The insulation consists of _______ layers.
A. two B. three C. four D. five
79. The underlined "puff up" in the second paragraph can be replaced by ______.
A. breathe deeply B. blow up C. hold tight D. spread out
80. The passage mainly tells us ______.
A. how penguins stay warm in cold places B. that penguins are a clever animal
C. how penguins keep their temperature D. why penguins can live a safe life
Come prepared: When you arrive at a race, your bike should be in race-ready condition.
Chain Management: Chain damage is still the number one problem with mountain bikes. Keeping your chain clean and well-oiled will help, as will frequent chain replacement. Periodic inspection of your chain for wear, stretch and damage may save you a long walk home.
Packing Tape: This can be used for rims trips, boots for fractured tires and a dozen more makeshift repairs. If you've flown to the race, it also saves you from having to borrow tape to close up your bike box for the flight home. Other musts: safety pins and plastic zip ties.
Pre-race: Visual inspections before any serious off-road ride, carefully examine the area where the tire hooks onto the rim and remove any foreign objects which could cause premature（比预期早的）tire wear.
Tire Pressure: Check tire pressure before race start. The recommended pressure is noted on the tire sidewall, usually 40 lbs., many racers run 50 lbs., or more for less rolling resistance.
Be Self-Contained: Make sure you are self-contained. Bring your own drinking water, food and first aid kit. Also have tools, spare parts, tubes, quick fills and a chain tool. Never suppose you can just borrow these items from a friend.
Post-race Visual Inspections: Inspect your bike after completing each event, especially before competing in a downhill event. Re-inspect before packing your bike for the trip home.
Have Fun!

Less than one year after France imposed(强加于)a nationwide ban on smoking in most public places, it will, from Jan. 1, 2008, extend the ban to bars, restaurants, hotels, nightclubs - and the most cherished of all: caf†s.
Ireland and Italy show that countries with longstanding smoking traditions may introduce bans fairly smoothly, as they did in 2004 and 2005. In Germany, where regulations vary locally, Berlin will join France on Jan 1. But fierce critics of the new law in France say it all but destroys the caf†'s basic function: to serve as the socioeconomic glue of society.
C†cile Perez, owner of La Fronde, a typical Parisian neighborhood caf† said: "In the morning, street cleaners in bright green uniforms sip coffee next to well-dressed businessmen; at lunch hour, working-class types rub shoulders with those of the latest fashion at the bar, while couples of all ages rub noses over salads; during the after-work rush, there is a steady soundtrack of clinking glasses combined with conversation; the constant, no matter what time of day, is the smoke that drifts through the air in curls and clouds, seemingly unnoticed."
"Our motto in France is: liberty, equality, fraternity," Olivier Seconda, a regular at the caf†, said.
"The caf† is the place that represents that. You're free to smoke, everyone pays the same price for a beer and different kinds of people talk with one another. This new law goes against that."
Seconda expects the ban to be felt even more strongly in small villages far from Paris, where the caf† is often the only means of social activity. "People already miss the space that allows people of all walks of life to share something-even if it is sometimes no more than a few words and the smoke floating between them."
69. In Germany, ______.
A. caf† smoking will be forbidden from Jan,1, 2008
B. the tradition of caf† smoking is and will be well-kept
C. local customs are well respected in terms of smoking
D. there are different regulation on smoking
70. C†cile Perez mentions the curls and clouds of smoke drifting through the air to ______
A. describe a friendly atmosphere B. show the beauty of his own caf†
C. support the ban on smoking D. remind us of something unnoticed
71. Olivier Seconda implies that ______.
A. the caf† provides people with enough liberty, equality, and fraternity
B. people, regardless of their social class, enjoy equal rights in a caf†
C. the new ban on caf† smoking should be put in effect only in villages
D. people would not find fun in a caf† without smoking a cigarette
72. The passage is written to _______.
A. show the writer's personal opinion against a new law
B. provide information for law-makers to pass a new law
C. tell why some people are unhappy about smoking ban in caf†s
D. compare attitudes to a law, held by people from different countries
The choice to adopt and hold gratefulness is the one that is different from those who suffer misfortune and those who enjoy a full life.
My mother died when I was 24. It was a very difficult time in my life - everything seemed to fall apart. I lost my job, and then my utilities were turned off. I had to take cold showers for six months. A neighbor who knew about my situation came to my house and made me an offer. I took care of her children as a job, and I no longer went hungry. I was surprised that someone would trust me－a young woman－with her children. And it was with the very confidence that before long I began taking care of other people's children, too. I have since moved 300 miles from Boise, Idaho. For more than 23 years I have made every effort to reach out to all the kind-hearted people who helped me when I was down and out. Without their trust, I don't know what I would have done. I am very involved in my community and volunteer at the local food bank, and I help out whenever I can. I'd like to owe what I am to whoever has offered me generosity.
If you are grateful for what you already have, the world will work together to give you more to be grateful for. Otherwise, the world will give you more to complain about.
Moreover, the true master learns to be grateful, in advance, for the things that are desired, because, being grateful in advance for some attainment or accomplishment does two very important things: one－it tricks your subconscious(潜意识)into believing that the goal is certain and two…it convinces other people, with whom you must interact to achieve your desires, that you know what you are about, that you are a winner, not a whiner(哀诉者).
65. The underlined "utilities" refers to such things as ______ in the passage.
A. gas and electricity supplies B. water and gas supplies
C. shower equipment and water supply D. heating and TV signals
66. The writer was grateful mainly for ______.
A. his neighbor's donation B. his community
C. having got the job D. others' trust
67. The writer's personal story in the second paragraph tells us that ______.
A. to be grateful will get you nowhere but away from home
B. we need to be grateful to be helpful and useful
C. a grateful person is most likely to be successful
D. the fragrance (芳香) stays in the hand that gives the rose
68. The best title for the passage would be ________.
A. A Thank-You Note to Trusting Neighbor B. You Are a Winner, Not a Whiner
C. Gratefulness Brings a Great Fullness to Life D. Be Grateful to Life in Advance

The fog was so thick that I couldn't see the man next to me. We were led down a road to the base of a hill. An officer, unknown to us, explained that the command wanted us to spread out on the road and fix bayonets(刺刀).When the signal was given, we were to creep up the hill and take the enemy by surprise with a bayonet attack.
I didn't think too much of the idea and about a dozen fellows agreed with me, but we lost in the vote. Some others didn't have bayonets and declared that the orders didn't apply to them, but their idea, too, was denied.
Up the hill we went, feeling our way along the ground with our feet. Step by step we advanced. It seemed like an ugly dream, but I knew it was all too real. I looked to my right and to my left to find any sign of my fellows. Much to my surprise, I could make out unclear forms on each side of me. I could hear whispers all along the line and louder orders to shut up!
While we were standing around arguing, the fog suddenly disappeared, just like somebody waved a magic wand(杖).We were caught out in the open with no cover in sight. The Chinese had been caught by surprise. Both sides just stared at each other, not knowing what was going on. A single shot rang out and somebody blew a whistle and shouted "Retreat"(撤退).We rushed out at full speed down the hill.
I don't speak or understand Chinese, but from behind us I could understand joyful laughter!

It seems as if cell phone could be the protection that parents expecting the kids to have freedom and be safe have been looking for. Let's 41 your 11-year-old son is going on a long bike ride with a friend, so they take along your cell phone 42 they need help. Not only could they call you if necessary, but 43 Global Positioning Systems (GPS) equipped on many mobile phones today, your son and his friend could also be 44 easily. Plus, with an additional service, you could track the boys' 45 location. Or consider this: If your daughter is 46 herself and three friends to a concert, she could 47 out exactly how to locate the concert location and get back home by using her equipped cell phone.And through a(n) 48 software package,you could 49 her whereabouts (行踪).
50 tracking devices as we all consider useful, however, have 51 .If the boys urgently needed help during the ride, 52 might be too late by the time someone found them. And if they wanted to, the concert-going girls could deviate (偏离) from the 53 route and go to a night club after the 54 -they could turn off the phone or leave it in their own car and drive with someone else.
