It is not unusual to stare at a long restaurant menu and not be able to decide what one wants to eat.At other times it is difficult to pick an item of clothing in a shop with plenty of items from which to choose.
   According to a new study published in Nature Human Behavior in October，this is the phenomenon of "choice overload （選擇超荷）".It's the result of a struggle （掙扎） in our brain，Science Daily reported.
   In the study，volunteers were given varying sets of six，12，or 24 landscape pictures.They were asked to choose one to be printed on a coffee mug.While they chose，a machine recorded their brain activities.
   According to the research，two parts of the brain - the anterior cingulate cortex （ACC）（前扣帶皮層）and the striatum （紋狀體） - were highly active in the process.The ACC is responsible for the potential costs of decisions while the striatum is to determine （決定） value，Neuroscience journal noted.The study suggests that our brain needs to weigh both reward and workload to make a proper decision.
   After further study，the researchers reported that these two parts are likely to be more active for the 12-item set than the other two sets.That's because 12 is a good number，not "too small" or "too large" in the choice pool.
   "As the number of options increases，the potential reward increases，but then begins to level off due to increasing amount of workload，" Colin Camerer，a professor of California Institute of Technology，US，told Science Daily.
   But that doesn't mean 12 is the magic number for decision making.According to Neuroscience journal，the proper number of options for a person is probably "somewhere between 8 and 15".Still，many people prefer to have a large number of options to choose from even if the experience can be distressing，researchers reported.
   According to the UK journal Medical News Today，it's partly because people tend to feel freer and more able to control their lives when there are more options.
   "Essentially，our eyes are bigger than our stomachs，" Camerer told Sci-news. "When we think about how many choices we want，we may not be mentally representing the frustrations of making the decision."

1．Throughout Europe golf has been popular for many years．A recent report says that in Great Britain alone，700 new golf courses（球場） will have to be built over the next ten years to meet people's needs．
This is all good news for golf lovers，but it worries those who want to protect the environment．Their argument is that the new courses are disturbing the balance of nature．Woods，ponds and fields are being dug up to make way for the courses．The birds and animals that used to live there are being killed or forced to leave．The amount of water that a club uses to keep its courses in good condition is reducing the amount of water available for industrial and other uses．The chemicals used to control insects are sinking into the underground water．
There may be some truth in this，but it is not the whole truth．The days are long past when building of any kind was allowed in beautiful places with no thought for the environment．Planning permission，nowadays，is as strict for golf courses as it is for any other type of development．Before any such project is given the go-ahead，many things are studied．It is only when it is clear no harm will be done to the area that the builders are allowed to move in．
A strong case can even be made that golf courses are actually good for the areas where they are built．Courses are usually built in the areas which are not areas of natural beauty．The new courses often make the area look livelier．To make holes more difficult，trees are planted and lakes are filled in around greens．Not surprisingly perhaps，it is not unusual to find that，within months of a course being completed，a lot of animals and birds have moved in．
Obviously，careful thought has to go into the design of the new courses．As few changes as possible should be made to the natural environment．Woods and wildlife should be also protected．But this can be，and is being，done．There is no reason why golfers and nature cannot live peacefully together．

（1）What is mainly discussed in Paragraph 2？

A．The rules for playing golf．
B．How to protect the environment．
C．The disadvantages of building golf courses．
D．Whether golf courses should be built or not．
（2）What is TRUE about building a new golf course nowadays？

A．It takes up too much land．
B．A lot of trees have to be cut down．
C．It is easy to get planning permission．
D．Many things will be taken into consideration．
（3）According to Paragraph 4，golf courses

．
A．make local areas look beautiful
B．provide more jobs for local people
C．a(chǎn)re harmful to the local environment
D．waste too much water and money
（4）Which best describes the author's attitude in the text？

A．Uninterested．
B．Worried．
C．Hopeful．
D．Doubtful．

2．Two young giant-panda twins born in the United States have returned home to China，but are struggling to adapt to the language and food．
The 3-year-old sisters，Mei Lun and Mei Huan，were the first surviving panda twins to be born in the United States，and were returned to China from Zoo Atlanta on Nov.5．But the pair still understand English better than Chinese，and prefer American biscuits to Chinese bread．
A zoo-keeper said that his main concern is that the pair are so addicted to American biscuits that everything they eat-from bamboos to apples-has to be mixed with biscuits．They even want to snack on （零食） biscuits when drinking water．
The zoo-keeper is trying to wean them off their biscuit habit，gradually replacing the American food with Chinese bread．Mei Huan is adapting，but Mei Lun doesn't want to touch the unfamiliar bread．
Mei Lun is the livelier of the two，often jumping onto the roof and hanging upside down from a rail，but her slightly younger sister Mei Huan is calmer，preferring to sit still，observe her new environment and occasionally snack on bamboo．
A language barrier is also reported．While the pair respond to their own names，and understand some English phrases such as"come here，"they don't understand the Sichuan dialect of Chinese．
The news caused some laughter on Chinese social media，with some users commenting that the pandas would soon get used to Sichuan's famously spicy cuisine．

（1）Based on the passage，which statement do you think is right？

A．The panda twins can fit in well in Sichuan．
B．The panda twins are only fond of Sichuan food and dishes．
C．The panda twins have been used to the new environment very quickly．
D．It's hard for the panda twins to get used to the new environment soon．
（2）What does the underlined part"wean them off"in the fourth paragraph mean？

A．help them get rid of．
B．help them form．
C．help them strengthen．
D．help them keep．
（3）From the passage we learn that of the two sisters，

．
A．Mei Huan mainly eats bamboo
B．Mei Lun is living a more active life
C．Mei Huan is not smarter than Mei Lun
D．Mei Lun is as quiet as her younger sister．
