WASHINGTON（AP）—Good news for dinosaur fans：There are probably a lot more of them waiting to be discovered．At least，their fossils are．
Peter Dodson of the University of Pennsylvania and Steve Wang of Swarthmore College estimate that 71 percent of all dinosaur genera（种类）—groups of dinosaur species—have yet to be discovered．
“It’s a safe bet that a child born today could expect a very fruitful career in dinosaur paleontology（古生物学），”Dodson said in a statement．
The estimate appears in Tuesday’s issue of Proceedings of the National Academy of Sciences．
Dodson—a professor of anatomy at Penn’s School of Veterinary Medicine and professor at Penn’s Department of Earth and Environmental Sciences—first estimated the potential number of dinosaur genera in 1990 and is revising that upward．
The estimates are based on the rates of discovery—about 10 to 20 annually—and the recent increase in finds of fossils in China，Mongolia and South America．
Dodson suggests that 1,850 genera will eventually be discovered．So far 527 genera have been found．
Fossilization itself is a rare event，they note，and as many as half of the dinosaur genera that ever existed may have left no remains．
“I would never suggest that this prediction．however statistically（统计上地）sound．is the final word on dinosaur diversity，“Dodson added．”My intention is to fuel the discussion using the facts at hand，and this is the best estimate we can make with the data available．”

He wishes the holiday season would end already . His back aches , his red suit feels like a spacesuit , his cheeks have gone tight from smiling for 12 hours —and still the kids keep coming and coming , like ants at a picnic . As Christmas becomes more commercialized (商业化) across the U. S. and Canada , so must Santas . As the holiday begins earlier each year, so must its spokesmen .
The questions from children these days are harder than ever . Now, with thousands of children expecting a father or mother serving in Iraq or Afghanistan , the questions are as heart-breaking as they are unanswerable . For example , “Can you please bring Daddy home from the war in time for Christmas morning ?”
Santas also have a pretty good chance of getting sued (指控). A professional Santa Claus in Canada told a story : A Santa had a girl on his knee , and he commented , “You have nice eyes and nice hair .” The girl later said it was sexual harassment (骚扰) . When a Santa feels anxious , he often shows it in the same ways ordinary people do : The Santas were always seen to hang around at the dinner table when the show ended . Many of them just sleep in bed for several days and don’t see other children again .

Animals can move from place to place, but plants cannot. When an animal is under attack, it can run away or fight back. Plants certainly cannot run away, and they lack teeth and claws. But plants can defend themselves by using both physical and chemical means.
Some plants have their own ways to keep animals away. For example, the leaves of the holly plant have sharp spines (刺) that discourage grass-eating animals. Holly leaves on lower branches have more spines than leaves on upper branches. This is because the lower leaves are easier for most animals to reach.
Some plants, such as the oak tree, have thick and hard leaves that are difficult for animals to eat. Some grasses may contain a sandy material; eating such grasses wears down the animal's teeth.
Many plants also have chemical defenses. Some plants produce chemicals that taste bitter or cause an unpleasant reaction. Some plants may fight against an attack by increasing the production of these chemicals. When a caterpillar (毛虫) bites a tobacco leaf, the leaf produces a chemical messenger. This messenger sends to the roots the information to produce more nicotine. The higher levels of nicotine discourage the caterpillar.
Many plants depend on both physical and chemical defenses. A certain plant in China, for instance, has prickly (多刺的) leaves, and each prickle contains poisonous venom (毒液) A single experience with this kind of plant will teach an animal to stay away from it in the future.

B. Its roots send a messenger to discourage the caterpillar.
C. Its roots increase the production of nicotine when it is attacked.

The Sahara Festival is a celebration of the very recent past. The three-day event is not fixed to the same dates each year, but generally takes place in November or December. It is well attended by tourists, but even better attended by locals.
During the opening ceremonies（仪式）, after the official greetings from the government leaders, people who attend the festival begin to march smartly before the viewing stands, and white camels （骆驼）transport their riders across the sands. Horsemen from different nations display their beautiful clothes and their fine horsemanship. One following another, groups of musicians and dancers from all over the Sahara take their turn to show off their wonderful traditional culture. Groups of men in blue and yellow play horns and beat drums as they dance in different designs（传统文化）. On their knees in the sand, a group of women in long dark dresses dance with their hair: their long, dark, shiny hair is thrown back and forth in the wind to the rhythm of their dance.
The local and visiting Italian dogs are anxious to run after hares. The crowd is on its feet for the camel races. Camels and riders run far into the distance, and then return to the finish Line in front of the cheering people.
Towards the evening, there comes the grand finale of the opening day, an extremely exciting horserace. All the riders run very fast on horseback. Some riders hang off the side of their saddles. Some even ride upside down -- their legs and feet straight up in the air -- all at full speed. Others rush down the course together, men arm in arm, on different horses. On and on they went. So fast and so wonderful!

There are two kinds of physical activity which require special training. The first demands exact careful movements of the muscles（肌肉）. This kind of activity must be strictly controlled because even a slight movement in the wrong direction will lead a mistake. To type quickly, for example, a person needs training; the slightest movement of a finger in the wrong direction may cause a spelling mistake. A dancer who has to dance on the point of her shoes or turn around on one foot must be trained for a long period of time before she can sense her own center and balance herself. You may have seen a girl walking on a rope across an empty space, which, too, requires a lot of practice.
The second kind of physical activity needs greater strength or extra effort. Most of us get tired if we try to run half a mile without stopping, but a specially-trained person can do this without much effort. Three years ago, some scientists carried out experiments, which produced meaningful and unexpected results. They wanted to find out whether a certain amount of physical exercise would injure those suffering from heart problems. They selected some male patients and trained them in continuous bicycle riding. They were surprised to find that the harmful effect of given amount of physical effort was actually less on the hearts of these trained patients than on those of the patients who were not similarly trained. This is important because it shows that regular physical exercise enables us to make better use of the oxygen（氧气）we breathe in and that this training, in fact, reduces the amount of work our hearts do. Many tasks which are hard for untrained people are not hard at all for trained people.
72．The first kind of physical activity must be strictly controlled because _________.
A．a mistake in the wrong direction is dangerous to the fingers
B．a wrong movement in a direction will cause no mistakes
C．a movement in the wrong direction will cause a mistake
D．a slight movement of a finger will lead to a mistake
73．What must a dancer do before she can balance herself?
A．She must dance on the point of her shoes. B．She must receive long-time training.
C．She must turn around on one foot. D．She must perform again and again.
74．The experiments done by some scientists showed that ________.
A．some male patients were asked to ride bicycles regularly in the experiments
B．the physical exercise had more harmful effect on the hearts of the untrained patients
C．the physical exercise was harmless to the male patients with heart trouble
D．the physical exercise could be helpful for the patients to take in more oxygen
75．What would be the best title for this text?
A．Training Our Bodies B．Physical Activities
C．Movement Training D．Extra Body Effort
