To many web-building spiders, most of whom are nearly blind, the web is their essential window on the world: their means of communicating, capturing prey (猎物), meeting mates and protecting themselves. A web-building spider without its web is like a man cast away on an island of solid rock, totally out of touch and destined to starve to death.
So important is the web to an orb-web spider’s survival that the animal will continue to construct new webs daily even if it is being starved. For 16 days the starving spider builds completely normal webs. Then, as the animal gets scrawnier (憔悴的), it constructs a wider-meshed web using fewer strands (线). Such webs would only trap larger prey, which is more economical from the perspective of a starving spider.
The spider stores energy by recycling web protein. It simply eats its own web each evening and re-uses it to produce new silk. In studies with radioactively labeled materials, it was found that 95 percent of web protein reappears in the next day’s web. Most of the energy needed for web-building is used in walking over the strands as they are laid down.
Scientists are impressed by the adaptability(适应能力) of the spider’s highly preprogrammed brain, which is larger for its size than the brain of any other invertebrate (无脊椎动物). If web-building is interrupted, or if some of the existing strands are destroyed, the spider simply goes back to see where the web is left off and then finished building a normal web. One spider will even finish building the incomplete web of another.

Most Beautiful of All
36 . Autumn was in the air. Rich, pleasant reds, painted by nature’s hand, were coloring some of the trees. On the ground a carpet of dry leaves had begun to form along the path. 37 . High in the sky we noticed a V-shaped flock of birds heading south for the winter. As we walked along, I smiled. Beauty was all around us. It felt so good to be out in nature. I felt blessed to be watching nature’s glorious creation at its best.
38 . She was an elderly lady with gray hair. She wore old jeans and work boots. Her sweater was worn out in places. She was carrying a trash bag in one hand and a pointed stick with a nail driven through it in the other. As she slowly made her way towards us, she stopped to jab (刺) a piece of trash that she had seen on the ground with her stick. 39 . When we
met she smiled and said hello to us. Her teeth were cracked and worn, but her voice was as youthful as I had heard in many a day. We talked for a bit and I thanked her for making our nature more beautiful with her work. She smiled again and said, “I just do what I can before continuing down the path.”
40 . May we all have as lovely a life as her.

Today, people are 44_ by light ----- even at night time. Much of this light _45_ where it shouldn’t be---it creates light 46_ .

Human beings experience problems _55_ light pollution too. Light affects some chemicals in people’s bodies. And people who are continually _56_ to light at night have higher rates of health problems.
People and animals need light, _57_ they also need darkness. Experts say that people must use light _58_ . Only use the amount of light that you _59_. Don’t think that more light is better light. People also can greatly _60_ light pollution by using well-designed lights, which only shine light where it should be. Using less light and better lighting decisions reduces the energy people use.

The Meaning of Dreams
Sleep and dreams have interested people for centuries. Scientists are learning more about sleep, but they still know very little about why we dream.
51 First, we have most of our dreams during REM(rapid eye movement)sleep. At this time, the brain is very active. Second, everyone dreams, even if we can't remember doing so when we awaken. 52 While we are sleep, it works more slowly and sometimes puts our thoughts and memories together in strange ways.
53 . Some believe that our dreams are associated with thoughts and feelings that we experience while we are awake. Many dream researchers think that a dream about death, for example, is really about an important life change. 54 . Dreams about a car or travel often represent feelings about your own life. Dreams about teeth—especially broken or loose ones—may indicate stress or fear. Dreams in which you are flying often represent freedom or escape.
Researchers think people in our dreams can tell us something about ourselves. If the person in the dream was yelling, for example, maybe you are angry. 55 .
There is still a lot about dreaming that we do not understand. By learning more about our dreams, we may learn more about ourselves.
A. Dreams may be more important than sleep.
B. Scientists do not know for certain why we dream.
C. If he or she was scared then maybe you are afraid of something.
D. Modern research can tell us some important things about dreams.
E. There are three things you should pay attention to to have a sweet dream.
F. Finally, a part of our brain helps us to understand daily experience we have.
G. Dreams about telephones are thought to be about giving or receiving messages.

Britons may like to complain a lot, but they rarely do so right now, explains BBC writer Ruth Margolis. They would rather grumble (发牢骚) afterward. This is because Britons hate to put someone out and cause any embarrassment. Margolis writes, “For instance, I’m much more comfortable just leaving that piece of raw chicken on my plate instead of complaining to restaurant staff. But beware: if this kind of thing happens when you’re dining with an American, they will most likely speak up on your behalf and not understand why you find this ashamed.”
In a BBC blog post comparing cultural differences between the UK and the US, Margolis mentions a few other things that Americans like to do that are offensive to Britons.
● Not making introductions
Margolis says most Britons dislike this approach because “talking to strangers without being introduced gives them a stomachache”. Americans rarely introduce a new friend to their friends at parties. Strangers are supposed to introduce themselves.
● “Quite” good
Using “quite” to mean “very” happens a lot in the US. But if you are invited to a dinner party in Britain, don't describe the meal as “quite good” if you want to express high praise. To Britons’ ears, “quite” detracts from the “good”: the meal was OK but could have been better.
● Money Talk
Americans can talk about money subjects for hours without feeling uncomfortable. For Britons, says Margolis, “Talking about how much we make is unthinkable — even 1ess so than discussing our feelings.”
● Over-politeness
“It’s not that I want shop assistants to be actively rude. But neither do I want to expend energy responding to someone who's been paid to ask: ‘How are you today?’” says Margolis. In the US, it is not unusual to be greeted by a perfect stranger as “honey” or “sweetie”. But Margolis says Britons find put-on friendliness, especially in stores, deeply irritating.
24. Margolis’ dining experience in Paragraph 1 shows that_______.
A. Britons are particular about foods
B. Britons are not good at complaining
C. Americans usually complain directly
D. Americans complain more than Britons
25. Which of the following might Margolis agree with?
A. Britons enjoy talking about their feelings.
B. Americans introduce themselves at parties.
C. Americans dislike talking to strangers at parties.
D. Britons feel happy if treated like close friends.
26. The underlined phrase “detracts from” in the text probably means ____.
A. differs greatly from B. increases the quality of
C. reduces the strength of D. draws attention away from
27. What does the text mainly talk about?
A. How to get on well with westerners.
B. How to start conversations with Britons.
C. Ruth Margolis’ tips on public behavior.
D. Some American habits that annoy Britons.
Nothing can spoil a vacation quicker than losing your money or credit cards. A few simple steps before you head out of the door can help protect your cash, card and personal information while you’re traveling.
Paul Stephens, a policy analyst San Diego, notes that people spend a lot of time planning their trips, from buying guidebooks to finding just the right beach outfits(装备).“But their eyes glaze(呆滞)over when the subject of keeping money safe comes up,” he said.
“Why not take a few minutes to do something that could probably save your vacation?” Stephens asked. ”In most cases, they can go on your to-do list with ’buy travel bags’ and everything else,” he added.
The top recommendation is to clean your wallet. Remove unnecessary credit cards and any other unneeded documents that could compromise(危及...的安全)your identity if lost or stolen while you’re on vocation.
Then make a photocopy of the cards you’ve decided to take along and keep it in a secure location with you(not in your wallet)or leave it with a trusted relative or friend back home. Then you will know who you need to contact and how to reach it if your wallet is missing.
‘Travelers should never leave their wallets or any identifying documents in their hotel room when they’re not there,” he said.” Choose a hotel with a safe to keep your valuable things in. Or keep your wallet and documents with you at all times. ”
12.According to passage, _______can destroy one’s vacation the most quickly.

What do a person, a tree and a bird have in common? _16_ All living things must have water to survive, whether they get it from a water fountain, a rain cloud or a little bottle attached to the side of a cage. Water is especially important to us human beings.
_17_ Water makes up more than half of our body weight. A person can't survive for more than a few days without water. Why? Our bodies have lots of important jobs and they need water to do many of them. _18_ Without oxygen, those tiny cells would die and our bodies would stop working.
Water is also an important part in lymph (淋巴液), a fluid that is part of our immune system and helps us fight off illness. _19_ Water is needed for digestive juices, urine (小便) and crap (大便). And water is the main ingredient in sweat.
Our bodies don't get water only from drinking water. Any fluid we drink contains water, but water and milk are the best choices. _20_ Fruit contains quite a lot of water, and we can tell that if we bite into a peach or a pear and feel the juice dripping down our chins! Vegetables, too, contain a lot of water --- think of cutting a fat tomato from the garden.
