題目列表(包括答案和解析)
In fall 2006，the National Basketball Association （NBA）started using basketballs made with synthetic ，or man-made ，material instead of leather（皮革）．They made the change be- cause they wanted every basketball they use to feel and bounce（彈起）the same．Not all leather balls are exactly alike in weight or how they bounce，but the synthetic balls are．
However，some players complained right away that the new balls bounced differently and were actually harder to control than the leather ones．
Physics helped answer questions about why the new balls felt different．For example，the scientists studied friction（摩擦力），which in this case affects the ability of a player to hold onto a ball．"The greater the friction，the better it will stick to his hand，"explains a scientist．
Tests on both wet and dry balls showed that while the synthetic ball was easier to hold onto when dry，it had less friction and became much harder to hold onto when wet．That's because sweat（汗水） stays on the surface of the synthetic balls but gets taken into the leather balls．
The scientists also tested bounce and found that the logo （商標(biāo)）printed on the new balls made their surface uneven（不平） and caused them to bounce a little strangely com- pared with the leather balls．
In January，the NBA went back to using the leather bails．They aren't perfect，but for now，that's just the way the ball bounces．
1．Why were the synthetic balls expected to be used in NBA according to the text?
A．Because they are easier to control． B．Because they waste less material．
C．Because they look exactly alike． D．Because they feel and bounce alike．
2．The ball is easier to hold on to_________
A．when friction is greater B．when friction is less
C．when it is heavier D．when it bounces strangely
3．The synthetic ball bounces differently from the leather one mainly because _________
A．it is wet B．it is dry
C．there's a logo on it D．its weight remains the same
4．It can be inferred（推斷） from the text that _________．
A．a(chǎn) synthetic ball takes in water faster than a leather ball
B．a(chǎn) leather ball is more difficult to make than a synthetic one
C．a(chǎn) synthetic ball is more expensive than a leather ball
D．a(chǎn) leather ball may increase its weight during a game
5．The underlined word" They" in the last paragraph refers to __________．
A．the synthetic balls B．the leather balls
C．the ball players D．the scientists
Six Chinese Characters
Dear students，our country has a long history．Chinese characters usually have more than one meaning and some of them are particularly loved by Chinese people．Here are the top six lucky ones．Please note we use “pinyin” here because “pinyin” is the Chinese spelling system for the characters．For example，“fu” is the “pinyin” for good luck in Chinese．“pinyin” “fu” is only the phonic（語音的）part of the character and if you want to know the meaning of good luck “fu”，you must read the Chinese character 福 because “fu” also represents（代表）other Chinese characters that sound the same．
1．福 “fu” 一一blessing，good fortune，good luck
Chinese character 福 “fu” is one of the most popular ones used during Chinese New Year．It is often displayed upside down on the front door of a house or an apartment．The upside down 福“fu” means good luck came since the character for upside down in Chinese sounds the same as the character for “came”．
2．祿 “l(fā)u” means prosperity
It is used to mean official's salary（薪水）in feudal（封建的）china．
3．壽 “shou” means longevity

4．喜 “xi” is Happiness．
The doubled character 喜 “xi” means double happiness．It is usually displayed everywhere at Chinese weddings．

Chinese often say “money can make a ghost turn a millstone”．It is to say money really can do a lot of things：but，still--money can't buy everything．

Bicycles are very popular around the world today．People ride their bicycles for exercise and enjoyment．In some places，people use a bicycle to get to work．In other places，bicycle riding is a very popular exercise to people who live in cities．But who invented the first bicycle? In 1791，a Frenchman named Comte de Sivrac invented and owned the first bicycle．Mrs. Sivrac rode（騎）the bicycle in Paris．The handles（把手）and the seat were wooden．This bicycle was very difficult to move．A rider even had to pick up the front wheel to change direction．Finally，the bicycle had no brakes for stopping or pedals for the feet! Riding a bicycle was a great risk．
In 1817，a German named Baron von Drais de Sauerbrun made the first bicycle better．The seat became more comfortable．The wheel could now change direction．His ride in the forest took only one hour instead of three hours on foot，which surprised people at that time．
