7．Blue-eyed people have been living in Europe for at least 7，000years，scientists have discovered．
A man who lived on the Iberian Peninsula before Europeans became farmers probably had blue eyes but dark hair and skin，according to scientists who have sequenced （排序） his DNA．This surprising combination of eye，hair and skin coloring may not have been unusual during his lifetime，but it is no longer seen among modern Europeans，the team reported Sunday in the journal Nature．
The man，a Neolithic hunter-gatherer known to scientists as La Bra?a 1，is of great interest to scientists because he offers a photograph of what was in Europeans'DNA before agriculture （農業(yè)） spread through the continent．Experts have understood that certain genetic （基因的） features spread quickly among humans after they led the farming lifestyle．La Bra?a 1shows that at least some of their expectations were correct．
The man's skeleton，along with that of a male companion，was discovered in 2006in a cave in what is now northeastern Spain．The site，known as La Bra?a-Arintero，sits about 5，000feet above sea level，and the cave provided a cold，refrigerator-like environment that preserved his DNA．
In the lab，scientists were able to take out enough DNA from a single tooth to reconstruct La Bra?a 1's entire genome （基因組）．They compared it to the DNA of other ancient Europeans and determined that he was a closer match with hunter-gatherers than with farmers．
When it came to genes that would influence La Bra?a 1's appearance，the researchers found that their 7，000-year-old subject had versions of two skin pigment （色素） genes that are either very rare or nonexistent among Europeans today．Then they looked at other places in the genome that influence pigmentation and found a mix of ancient and modern gene variants （變體）．Taken together，La Bra?a 1's DNA"is likely to have resulted in dark skin pigmentation and dark or brown hair，"they wrote．
However，his DNA indicates that his eyes were most likely blue，the scientists found．This suggests that gene variants for light-colored eyes and skin did not spread together，they wrote，adding that La Bra?a 1's combination"of dark skin and non-brown eyes is unique and no longer present in contemporary European populations．"Today，a blue-eyed person would usually have fair skin．
To get some idea of whether La Bra?a 1's coloring was unusual for his day，the researchers will try to sequence the DNA of his companion，who has been named La Bra?a=2．
25．Why scientists are interested in La Bra?a 1？B
A．They can know Europeans'DNA．
B．They can know European hunter-gatherers'DNA．
C．They can know the ancient agriculture in Europe．
D．They can know some of their expectations were correct．
26．La Bra?a 1was well preserved due toD．
A．dry weather        
B．a high cave     
C．proper protection          
D．cold conditions
27．Which of the following is TRUE according to the passage？A
A．La Bra?a 1's DNA influenced his appearance．
B．La Bra?a 1's appearance influenced contemporary Europeans．
C．La Bra?a 1's gene variants spread together．
D．La Bra?a 1's genes are completely different from contemporary Europeans'．
28．The last paragraph suggests thatD．
A．La Bra?a 2has the same genome with La Bra?a 1
B．Blue-eyed people were common in Europe 7，000years ago
C．Bra?a 1's combination of dark skin and non-brown eyes is unique
D．It's not certain that La Bra?a's appearance was common at his time．

4．In this section we consider what you can do to train your brain to improve your game playing skills．
1．Daily workout
It is very easy to find tactical puzzles and train．However，you must try to solve them．Don't just stare at the position for 10seconds and then turn to the solution．You won't learn anything．Have a go at trying to solve the puzzle．If you got it right then great----well done．However，if you got it wrong，then have another look．Ask yourself questions such as the following：
•Why did I get it wrong？
•What was wrong with my solution？
•What was the weakness that the tactic exploited？
Where can you find tactical puzzles？
It's easy．They are everywhere．Many newspapers，including Independent，and magazines have a daily or weekly chess puzzle．Key"chess puzzles"into Google and you'll find a whole load of them．There are plenty of puzzle books．
2．Use software
Nowadays chess software is terribly cheap．World Champion Vladimir Kramnik recently lost a match 4-2against a software program．This program is available for about￡30．
In general，people use chess software for the wrong reasons．They often play game after game against the machine and get beaten every time．Bored with this，they turn the playing level right down so that the program is almost playing random moves and then they can beat it every time and feel better．
Neither method will help you improve．However，chess software can be a fantastically useful learning tool if used in two particular ways．
The first is if you have tried to solve a puzzle but it's a bit too difficult and you don't really understand the solution．Never mind----well done for trying．Now set the position up on the program and try different moves．Chess software is faultless at tactical play．It will instantly tell you the right and wrong moves and why they do or don't work．
Secondly you can run over games you have played to learn where you have gone wrong and where you could have improved．Get into the habit of keeping the score （i．e．writing down the moves） of games that you play．This will help you to improve and refine your understanding of tactical themes and patterns．

56．What would be the best title of this passage？D
A．How to Train Your Brain
B．Where to Find Tactical Puzzles
C．Daily Workout and Use of Software
D．How to Improve Your Chess-Playing Skills
57．The underlined part"tactical puzzles"in the second paragraph most probably meansB．
A．puzzles making us better understand themes and patterns of difficult games
B．puzzles showing us how to train our brains to think more effectively
C．puzzles teaching us some skills to play more difficult games
D．puzzles only teaching us how to play chess games well
58．Which of the following would be the right way of using chess software？C
A．Playing as many games against the machine as possible．
B．Always trying difficult puzzles to improve your chess skills．
C．Running over games you've played to learn from mistakes and improve．
D．Turning the playing level down to build your self confidence and feel better．
59．What does the writer think about chess software？A
A．Chess software will help a lot if properly used．
B．Chess software below 30pounds is too cheap to use．
C．Chess software is a fantastically useful learning tool in daily work．
D．Chess software helps improve understanding of tactical themes and patterns．

Food enters the body through the mouth．Waste materials （undigested food） leave the body through the anus（肛門）．The anus is at the end of the large intestine．
Digestion is a step-by-step process．（40）B It takes food from one to two days to pass through the entire digestive tract．
