13．Agricultural experts met in Ethiopia last week to discuss ways to help sub-Saharan Africa become a major producer of wheat．The area traditionally produced little wheat，while North Africa was the grain basket．
Wheat production fell sharply in sub-Saharan countries during the 1980s．In the 1960s，attempts were made to grow wheat in sub-Saharan Africa，including South Africa and Zimbabwe．But those countries found it was less costly to import wheat from Europe and the United States．Another problem is that Africa's wheat farms were often far from population centers．There also were transportation issues．And some lowlands were not a good place to grow wheat．
Hans Joachim Braun，one of the experts，says now is a good time to increase wheat production．In the last four years we have seen three major price hikes，where the wheat price and other staple process （主食加工）exploded．And that puts a big，big bill on countries which are depending on wheat imports，and Africa is the biggest wheat importer．
He also says demand for wheat in sub-Saharan Africa is growing faster than for any other crop．With higher income people would like to have more diversified（多样化）food．But that is possible not the most important one．The most important one is that there is a tremendous migration（移民）of in particular male labor to the cities．And wheat products are convenient food because you can easily buy it．It's easy to process and you also can store it for a few days，which is different from some of the maize and rice products．
There are three possible challenges for growing more wheat in Africa：climate change，disease and pests，like insects．Mr．Braun says rising temperatures should not have a major effect on wheat．In fact，he says，it could help wheat grow in areas with high rainfall totals．As for fighting disease and pests，experts suggest growing more resistant crops．In addition，railroads and roads would have to be improved so large amounts of wheat could be moved to large markets．

39．What does the word"hikes"in Paragraph 3probably refer to？B
A．big changes 
B．large increases 
C．long trips 
D．big bills
40．Wheat price exploding indicatesA．
A．sub-Saharan countries need to increase wheat production badly
B．sub-Saharan countries have to issue more money
C．sub-Saharan countries should grow more Corn
D．importing much wheat is urgent
41．Why is there a higher demand for wheat in sub-Saharan Africa？C
A．Because the number of hungry people there is increasing．
B．Because higher income people have the diversified need of food．
C．Because male labor are crowding into the cities．
D．Because the wheat price is lower．
42．According to Mr．Braun the main challenges for growing more wheat in Africa areD．
A．climate change and disease
B．resistant crops and climate change
C．rising temperatures and disease and pests
D．disease and pests and inconvenient transportation．
10．A dog-lover has invented a high-tech way of feeding his pet by Twitter（推特，流行社交网络）．Computer expert Nat Morris，30，has designed a system to give his pet a"tweet treat"by sending him a Twitter message．
His dog Toby gets some delicious dog biscuits from a computer-controlled food machine whenever Nat sends a message to"@feedtoby"．
Nat often works away from home and isn't always able to feed Toby by hand．But his new invention  allows Nat to feed his dog from anywhere in the world．
Nat said，"Toby absolutely loves it．At first he didn't know what was going on．Now he sits underneath the machine，wagging his tail and waiting for the treats to drop．"
Nat fills the food machine with small pieces of dog biscuits，but not too many in case four-year-old Toby gets too many messages．And Nat has even equipped his house with an online camera so he can see Toby enjoying the food at his home．
But one problem is that friends and family have been so amazed with the"Tweet treat"machine that．they have starting to send tweets to Toby too．So Nat has had to restrict feeding time to make sure Toby doesn't turn into Tubby．
"People have been sending him food at all hours of the day，so I had to limit it to between 9 a．m．and 9 p．m..I'm thinking of doing an updated one which measures his weight before he is fed，just to make sure he's not putting on too much puppy fat，"explained Nat．
How Nat's Twitter Feeder Works：
When a message is sent to@feedtoby it is received by a mini-computer that is linked to the food machine．
When the mini-computer receives the message，a bell rings and Toby comes running over and sits in front of the feeding machine．Next the machine's motor pulls open a trap door which releases a serving of food．
The doggy biscuits then drops into Toby's food bowl．Finally a digital camera takes a photo of him and sends it back to Nat on Twitter-so he knows Toby has been fed．

17．It all began with a stop at a red light．
    Kevin Salwen was driving his 14-year-old daughter，Hannah，back from a sleepover in 2006 While waiting at a traffic light，they saw a black Mercedes Coupe on one side and a homeless man begging for food on the other．
"Dad，if that man had a less nice car，that man there could have a meal，"Hannah protested． The light changed and they drove on，but Hannah was too young to be reasonable．She pestered （纠缠）her parents about inequity， insisting that she wanted to do something．
"What do you want to do？"her mom responded．"Sell our house？"
Warning!Never suggest a grand gesture to an idealistic teenager．Hannah seized upon the idea of selling the luxurious family home and donating half the proceeds to charity，while using the other half to buy a more modest replacement home．
Eventually，that's what the family did．The project-crazy，impetuous （鲁莽的） and utterly inspiring-is written down in detail in a book by father and daughter scheduled to be published next month："The Power of Half．"It's a book that，frankly，I'd be nervous about leaving around where my own teenage kids might find it．An impressionable child reads this，and the next tiling you know your whole family is out on the street．
At a time of enormous needs in Haiti and elsewhere，when so many Americans are trying to help Haitians by sending everything from text messages to shoes，the Salwens offer an example of a family that came together to make a difference-for themselves as much as the people they were trying to help．In a column a week ago，It described neurological （神经学的）evidence from brain scans that unselfishness lights up parts of the brain normally associated with more primary satisfaction．The Salwens'experience confirms the selfish pleasures of selflessness．
Mr．Salwen and his wife，Joan，had always assumed that their kids would be better off in a bigger house．But after they downsized，there was much less space to retreat to，so the family members spent more time around each other．A smaller house unexpectedly turned out to be a more family-friendly house．

12．Turning the lights out or wearing a blindfold while eating could be a quick way to lose weight，according to scientists．The simple trick works because it stops diners eating for pleasure rather than for calories．It also triggers （引发） a part of the brain that is worried that unseen food may go bad．
An experiment by the University of Konstanz，in Germany，found that people who were blindfolded consumed nine percent fewer calories before they felt full，compared to those who could see．They also vastly overestimated how much they had eaten because they could not see how much was left on the plate．Blindfolded volunteers estimated they had eaten 88percent more than they actually had．
Scientists believe that not seeing food on the table also allows the body to know when it is full in real time rather than remembering past experiences where it might have taken a full plate to feel full．
In the experiment，50 people were blindfolded and 40were allowed to see their food．All were told not to eat within two hours of the experiment．They were then given three 95g bowls of chocolate ice cream and invited to eat for 15minutes．Their bowls were taken away and the remaining ice-cream weighed，while the participants were quizzed on how much they thought they had eaten．
On average the group who could see ate 116g while the blindfolded groups ate 105g．However，the blindfolded group believed they had eaten 197g while compared with 159g for the non-blind volunteers．They were also asked how pleasant the ice-cream tasted and the blindfolded group rated lower than those who could see．
"The experienced pleasure of eating was significantly lower in the blindfolded group．Not seeing the food might have decreased the appetite．Sight plays an important role in the eating experience and in the overall dining experience．"
Previous studies have shown that the visual influence of food plays a large part in the taste．While restaurants that allow diners to eat in the dark state that it triggers other senses，in fact eating in darkness is likely to taste far milder than usual．
63．With the lights out，diners eat less partly becauseD．
A．they want to quickly finish their meals
B．they trust their feelings more than ever
C．they focus more on fun than the calories
D．they worry about the quality of the food
64．We can learn from the passage that the blindfolded groupB．
A．spent a much longer time eating the same food
B．believed they ate more than they really did
C．depended on past experiences to feel full
D．thought the food tasted better than usual
65．The last two paragraphs tell us thatA．
A．diners are likely to lose their appetite eating in darkness
B．senses rather than sight play an important role in the taste
C．findings of this experiment differ from the previous studies
D．restaurants benefit a lot from allowing diners to eat in the dark
66．The main purpose of the passage is toC．
A．provide statistics related to eating in the dark
B．offer reasons for people to eat in the dark areas
C．inform the readers of the result of an experiment
D．persuade the readers to lose weight in a new way．
