American black bears appear in a variety of colors despite their name. In the eastern part of their range(地理分布区), most of these bears have shiny black fur, but in the west they grow brown, red or even yellow coats. To the north, the black bear is actually gray or white. Even in the same litter(窝), both brown and black furred bears may be born.
Black bears are the smallest of all American bears, ranging in length from 5 to 6 feet, weighing from 300 to 500 pounds. Their eyes and ears are small and their eyesight and hearing are not as good as their sense of smell. Like all bears, the black bear is shy, clumsy(笨拙的) and rarely dangerous. However, if cornered, me black bear can become a fearful enemy.
Black bears feed on leaves, roots, fruit, insects, fish and even larger animals. One of the most interesting characteristics of bears, including the black bear, is their winter sleep. Unlike many other animals, bears do not actually hibernate(冬眠). Although the bear does not eat during the winter months, its temperature remains almost normal, and it breathes regularly four or five times per minute.
Most black bears live alone, except during the mating season (交配李节). A litter of one to four cubs is born in January or February and they remain with their mother until they are fully grown or about one and a half years old. Black bears can live as long as thirty years in the wild, and even longer in game preserves set aside for them.

It takes more than just practice to become an Olympian. Gold medal performances require some serious nutrition. Have you ever wondered what these successful athletes eat to stay in peak shape?
Keri Glassman, a registered dietitian and founder of Nutritious Life Meals, appeared on "Good Morning America" today to give you a glimpse into the diets of some top athletes. Some of their meals could surprise you.
Crazy Calorie Count
Glassman said Olympians eat a lot of food---quantities that for ordinary people would constitute pigging out. One secret of swimmer Michael Phelps' astonishing performance in the 2008 Olympics in Beijing was consuming as many as 12,000 calories in one day.
Athletes can eat like this and not gain any weight because their workouts are intense. According to Glassman, Phelps' workouts can burn 4,000 to 6,000 calories in a day, and those calories must be replenished (补充) in order to train the following day.
Snacking Secrets
Some athletes eat wacky (strange, unusual) foods that they swear improve their performance. Yohan Blake, the Jamaica sprinter and 100-meter world champion, has been making waves for stealing champion sprinter Usain Bolt's thunder on the track during the Olympic trials. Asked about how he gets his stamina, Blake answered that he eats 16 bananas per day, Glassman said.
Jonathan Horton, the lead gymnast on the US team, has a blood sugar problem. His solution is honey. When he starts to feel shaky at the gym, he takes swigs of honey to boost his energy, Glassman said.
Foods for Recovery
What are the best foods to help the body recover after rigorous (strict) competition?
For Olympic swimmer Ryan Lochte, the recovery meal is grilled chicken breasts with Alfredo sauce, whole-grain spaghetti and a salad with lemon juice and olive oil. Lochte, who recently cut out junk food, candy and soda, has undertaken a rigorous strength-training regimen(养生法) that involves flipping tractor tires, dragging shipyard chains and tossing beer kegs, Glassman said.What’s the best title of this passage?

One of the world's richest men has taken a close interest in one of man's most basic functions: visiting the toilet.Bill Gates’ charitable organization, the Bill and Melinda Gates Foundation, is looking for inventors to design the loo of the future, which, they hope, would improve sanitation for millions of people around the world.
So, what's wrong with the traditional flush toilet? Firstly, it wastes a huge amount of potential drinking water.Secondly, they are more likely to cause pollution.This is a real problem in many areas of the developing world, where, according to United Nations’ estimates, unsafe sanitation causes half of all hospitalizations.Younger people are particularly at risk.Illnesses which cause diarrhea are responsible for the deaths of about 1.5 million children a year.Finally, standard lavatories simply aren't practical in remote areas.
The challenge set by Bill Gates was to come up with a latrine which works without running water, electricity or aseptic tank.It also needed to operate for less than 5 cents.28 designs were displayed at the recent event of the Toilet Fair in Seattle, USA.Among them was one which turned human waste into electricity using microwaves, another which converted human waste into charcoal, and yet another which used urine for flushing.
But the winner was a solar-powered design which generated hydrogen gas and electricity.The team from the California Institute of Technology(CIT)picked up a prize of $ 100,000.
But clearly Bill Gates doesn't feel he's flushing money down the toilet.After the Seattle event he said, "We couldn't be happier with the response we've gotten," Gates has even promised $370 million more to the future toilet project.They hope to field test more prototypes over the next three years.Why is Bill Gates paying people to invent new toilets?
A.Because he wants to test people's sense of creativity. |
B.Because he wants to improve sanitation for many people. |
C.Because he thinks the traditional ones are out of fashion. |
D.Because he can't design this kind of things himself. |
Which of the following is NOT a problem with the traditional flush toilet?
A.They waste too much water. | B.They might cause diseases. |
C.They are not always practical. | D.They are too complicated to use. |
The underlined word "latrine" in the third paragraph might have similar meanings to the word "__" in the text.
A.loo | B.sanitation | C.diarrhea | D.prototype |
The team from CIT won the prize because their design.
A.can change human waste into electricity |
B.can turn human waste into charcoal |
C.can produce power with solar energy |
D.can use urine for flushing |
If people "flush money down the toilet", they are.
A.showing off their wealth | B.angry with their working conditions |

A Avoid asking your child too many questions B Tell your child stories about your growing up C Don’t judge or criticize your child D Listen to your kids with respect E Provide pressure-free conversation opportunities F Ask children gently what they think |
If your child has gone from a continuous chatterbox to making conversations that consist mostly of yes and no, it’s time to consider these tips on how to talk to kids, so you’ll know what’s going on in your child’s world.
The quickest way to get kids to shut up and, as a result, shut you out of their lives is to continuously press them about things. A more effective way is to sit back and patiently wait for them to open up in a low-stress family and then be prepared to listen.
Parents can sometimes make kids at a young age decide it is best not to talk about something when they are criticized. If you really want to know what’s on your child’s mind, then avoid passing judgment and focus instead on why something seems important to your child.
If you want to raise a creative and independent thinker, stop telling your child what he ought to feel or think. You can gently encourage additional conversations by simply asking why he feels the way he does or what he would do in a certain situation.
You may think you’re just asking questions out of curiosity when communicating with your child, but an endless stream of questions about what they did, whether everyone got along, if they went to the bathroom, ect., are enough to make anyone shut up! Practice patience and let your kids open up on their terms.
Kids can relate to you and other adults when you tell your stories happening when you were their age. Talking to kids by telling them about things like something embarrassing that happened or the first crush(迷恋) you had helps them to connect with you and understand that you might actually know what they are going through!
Driving a car is not just handing controls and judging speed and distance. It requires you to predict what other road users will do and get ready to react to something unexpected. When alcohol is consumed, it enters your bloodstream and acts as a depressant(抑制药), damaging eyesight, judgement and co-ordination(协调), slowing down reaction time and greatly increasing the risk of accidents. Even below the drink driving limit, driving will be affected.
Alcohol may take a few minutes to be absorbed into the bloodstream and start action on the brain. Absorption rate is increased when drinking on an empty stomach or when consuming drinks mixed with fruit juice. To get rid of alcohol from the body is a very slow process and it is not possible to speed it up with any measures like taking a shower or having a cup of tea or coffee.
The present Road Traffic Ordinance states clearly that the limit of alcohol concentration is:
·50 milligrams of alcohol per 100ml of blood; or
·22 micrograms of alcohol per 100ml of breath; or
·67 milligrams of alcohol per 100ml of urine(尿液).
Drivers who cause traffic accidents, or who commit a moving traffic offence or are being suspected of drink driving will be tested.
Any driver found drinking beyond the limit will be charged. The driver declared guilty may be fined a maximum of HK$25,000 and be sentenced to up to 3 years in prison and punished for 10 driving-offence points; or temporarily banned from driving.
The same punishment applies to failing to provide specimens(样本) for breath, blood or urine tests without good excuse.
Drink driving is a criminal offence. Be a responsible driver, think before you drink. For the safety of yourself and other road users, never drive after consuming alcohol. The first paragraph is mainly about.
A.the introduction of driving skills |
B.the damage of drinking to your body |
C.the effect of drinking on driving |
D.the process of alcohol being absorbed |
The underlined word “it” in the second paragraph refers to “”.
A.alcohol | B.absorption | C.blood | D.process |
Which of the following is TRUE according to the passage?
A.Drinking below the drink driving limit has no effect on driving. |
B.Alcohol is taken in more quickly when drunk with fruit juice. |
C.Having a cup of tea helps to get rid of alcohol from the body. |
D.50 milligrams of alcohol per 100ml of breath is below the drink driving limit. |
