Picture the scene: the battery on your mobile phone has run out． You can't make any calls for help and no one can contact you． You are all alone - well, not quite． Just reach into your pocket and take out a piece of sugar．Put it into the battery, wait a minute, and you're back on the phone．
Thanks to a couple of American scientists, this situation could become real．Swadesh Chaudhuri and Derek Lovely have invented the"bacteria battery" - powered by bacteria that eats sugar and turns it into electricity．
"This is a special organism," Lovely said．"You can harvest enough electricity to power a cell phone battery for about four days from a spoonful of sugar．"
In the past, bacteria batteries have been expensive and not long-lasting． But this battery uses more efficient bacteria that can turn 80 percent of sugar into electrical energy． This is 30 percent more than similar batteries can manage．
The bacteria battery could become as small as a household battery． It's also cheap and stable, as sugar can be taken from waste and crops．
But the sugar to electricity process is slow: it could take weeks for the bacteria to digest a cup of sugar．And it produces "greenhouse" gases which pollute the environment．
The scientists understand there is a lot more work to be done． "It is still young," said Lovely．"Where we are now is where solar power was 200r 30 years ago．"
But he believes the battery could be used in scientific equipment at the bottom of the ocean．Other ideas include using sugar in the blood to run medical devices in the human body, and taking sugar from animal waste to provide energy to power homes in rural areas．
1.This passage is mainly about_ ．
A． how to change sugar into electricity
B． a scientific invention of a new kind of bacteria battery
C． a new way to reduce pollution caused by mobile phones
D． a new kind of mobile phones and its future
2.Which of the following is not the strong point of the newly-developed battery?
A． Convenient． B．Stable． C． Inexpensive． D． Quick．
3.The underlined sentence in the 7th paragraph actually means ．
A． the bacteria battery shares some similarities with solar energy
B． scientists will continue their work until they find solar power
C． there is much room for the improvement of the bacteria battery
D． the bacteria battery will get popular in 20 0r 30 years
4.According to the passage, who will find the bacteria battery less useful?
A． Farmers． B． Divers． C． Doctors． D． Electricians．

C
Can you train your cat to actually use your toilet? Can you not have to deal with litter boxes any more? Well for many people the answers to these questions are yes．
You may have heard that some people have managed to train their cats to use the human toilet, Well this is correct．One advantage to this is the fact that you no longer have to lug heavy bags of litter home from the supermarket, or worry about cleaning out the dirty litter everyday．
Like any other cat training program, training your cat to use the toilet takes times and patience, you just can put your cat on the toilet and hope that they can use it．
By slowly shaping your cat’s behavior over a couple of weeks, you too can end lugging heavy bags of cat litter home from the supermarket．First, start by slowly moving the litter box closer and closer to the toilet each day, so your cat gets used to being in the bathroom and being around the toilet．
Next, when you have had to litter box next to the toilet for several days, slowly raise the litter box higher and higher each day until it is at the level of the toilet．Then find an insert for the top of the toilet, like a shallow pan that can sit in the rim of the toilet and hold litter．
Once your cat gets used to using this litter pan on top of the toilet for a week or so, try removing the pan and your cat should be able to use the toilet．
Like any cat training program, it takes time and effort on the part of the cat owner to do this．Don’t get frustrated with your cat if she is not learning as fast as you would like, many cats learn at their own pace．With a little effort you too can have a toilet trained cat．

A．keep the toilet clean
B．keep the cat clean
C．save a lot of trouble
D．save a lot of money

A．quick B．Complicated C．difficult D．gradual
66．When you have managed to get your cat to use the toilet, the litter box ．

C．should be kept where it is D．should be put back where it was
