The smart phone has brought us great convenience. However, it has also brought us some problems.

One possible version :

The smart phone has brought us great convenience. Howev?er, it has also brought us some problems. First of all, as we all know, the smart phone can store a great deal of information, which makes our memory get worse and worse. Besides, no one can ignore the fact that a growing number of people are occupied in chatting online, so it will be difficult for them to communicate with others face~to-face in real life. In addition? some teenagers are addicted to playing Internet games, resulting in their suffering for a poor sleep, which does great harm to their health. Last but not least, some students prefer to surf the Internet to search for the answer rather than think it by themselves even when they do their homework. As a consequence, in my opinion, we should use the smart phone correctly instead of depending on it too much in our daily life.

Scientists in theUKhave grown a living human "brain". The team at Aston University created a tiny bunch of cells which act like a mini nervous system.

They believe it could help find a cure for worse mental conditions like Parkinson's disease. Professor Michael Coleman is leading the research programme. He explained, "We are aiming to be able to study the human brain at the most basic level, using an actual liv?ing human cell system. Cells have to be alive and oper?ating efficiently to enable us to really understand how the brain works. The experiment involves changing cells from a cancer tumour (肿瘤)and making them be?have like brain cells.

Although far from finished, researchers hope the false brain cells will give them a greater understanding of how real brains work. This, in turn, could signifi?cantly further research into conditions which affect the brain. Neil Hunt, chief leader of the research group, said, "It is still very early days, but in the future the re?search could lead to a useful tool for looking into dementia (痴呆)."

The technique could also provide a way to carry on animal tests and is being supported by the Humane Re?search Trust ( HRT). The scientists predict that over the next ten years a million people will develop dementia. Professor Coleman believes their findings could change this. He said, "We hope our research will provide scien?tists with a new and highly relational human experimen?tal model to help them understand the brain better and develop new drugs to control the related disease. How?ever, the biggest challenge at present is that we are greatly short of fund, which will slow our research.,,

For foreigners, entering a public toilet inChinacan be a horrifying experience. In the 1990s, a third of all complaints to tourism officials in Beijing concerned the design, and the bad smell of public toilets.

China has battled smelly toilets for at least 2 , 000 years. In the Kingdom of Wei (220—265AD) , visitors to the palace bathrooms would find boxes to cover their noses and ward off unpleasant smells. Both flushing (冲水)toilets and toilet paper were invented in China, however? only for the use of the emperor.

Today Chinese scientists have claimed victory in their battle to improve public restrooms, introducing a bacterial spray that can almost eliminate the bad smell. First, a set of six types of bacteria work to break down the smelly compounds and then a perfume made from or?ange skin lightly scents(使芳香)the air. The "smell-free toilet" study from the Chinese Academy of Sciences was declared the "ultimate" cure to an "urgent" national issue.

"Five scientists have worked on this from 2011 to the beginning of this year," said Dr Yan Zhiying, a bacteriolo?gist with the Academy's Chengdu Institute of Biology, adding that they had spent £140, 000 on the project.

"Some local government officials here visited a sew?age (污水 ) plant and saw that the treatment technology had come from Japan. They wanted a home-grown solu?tion so they asked us to work on it," he added. "We ob?tained bacteria from all types of waste from humans, pigs, chicken and ducks, and we tested our compounds one by one," he said. "The smells coming out of public toilets, or trash cans, are made up of more than 160 dif?ferent compounds," he explained, adding that their bac?teria spray can change and absorb many of them.

He boasted that the Chinese formula(配方),which costs only around £5 per litre, has no side effects and can be used to remove any bad smell.

D.160 smelly compounds

3.Which has not been mentioned as an advantage of the bacteria spray?

A.Low price.

B.No side effects.

C.Removing bad smells.

D.Beautiful design.

4.Which can we infer after the spray is used in toilets inChina?

A.People needn't use flushing toilets.

China's new term, Tuhao, may be in next year's Oxford English Dictionary. The word caught the at?tention of the dictionary's editing team after BBC's re?cent programme on influential Chinese words. "If its in?fluence continues, it is very likely to appear on our up?dated list of words," said Julie Kleeman, project manag?er with the editing team.

In Chinese "tu" means uncouth(笨拙的)and "hao" means rich. It has traditionally been referred to rich people who throw their weight around inChina's coun?tryside. The word became more popular in September with the launch of Apple's new gold-coloured iPhone, which is loved byChina's rich people. The colour be?came known as "Tuhao gold". The word is now also used by the online community to refer to people who have the cash but lack the class to go with it. Kleeman also mentioned two other Chinese words―Dama and Hukou―which may also make it into the dictionary.

People can have an intuitive(直观的)grasp of the meanings if they see pinyin, Kleeman said, adding that people avoid using an English word to keep the original meaning.

"We have nearly 120 Chinese-linked words now in Oxford English Dictionary," she said. Some of them are guanxi, which means connection and taikonaut, a mix of taikong, meaning outer space, and astronaut.

The new words will be first uploaded on the official website before the dictionaries arrive. The online ver?sion is also renewed every three months. "It at least broke our old rules. It used to take 10 years to include a new word but now we keep the pace with the time," ac?cording to a statement from ex-chief-editor John Simpson.
