4、“Mobile phones killed our man,”screamed one headline last year. Also came claims that an unpublished study had found that mobile phones cause memory loss. And a British newspaper devoted its front page to a picture supposedly showing how mobile phones heat the brain.

For anyone who uses a moblie phone, these are worring times. But speak to the scientists whose work is the focus of these scared and you will hear a different story.

What we do have, however, are some results suggesting that mobile phones’emission(散发)have a variety of strange effects on living tissue that can’t be explained by the general radiation biology. And it’s only when the questions raised by these experients are answered that we’ll be able to say for sure what moblie phones might be doing to the brain.

One of the odd effects comes from the now famous”merrory loss” study. Alan Preece and his colleagues at the University of Bristol placed a device that imitated the microwave emission of mobile phones to the left ear of volunteers. The volunteers were all goood at recalling words and pictures they had been shown on a computer screen. Preece says he still can’t comment on the effects of using a mobile phone for years on end. But he rules out the suggestion that mobile phones have an immediate effect on our cognitive(感知的)abilities.”I’m pretty sure there is no effect on short-term memory,” he says.

Another expert, Tatterasll, remarked that his latest findings have removed fears about memory loss. One result, for instance, suggests that nerve cell synapses(神经元突触) exposed to microwaves become more----rather than less-----receptive to under-going changes linked to the memory formation.

It would be an even happier outcome if microwave turned out to be good for you. It sounds crazy, but a couple of years ago a team led by William Adey at the Veterans Affairs Medical Center in California, found that mice exposed to microwave for two hours a day were less likely to develop brain tumours(肿瘤) when given a cancer-causing chemical.

So should we forget about mobile phone radiation causing brain tumours and scrambling our minds?

“If it doesn’t certainly cause cancer in animals and cells, then it probably isn’t going to cause cancer in humans,”says William. And while there’s still no absolute evidence that mobile phone does mangle your memories or give your cancer, the consensus is:Don’t panic.

3、Let’s face it. Business trips aren’t the easiest. You are away from friends and family and must make meetings with partners the best you can. They can be stressful from the car ride to the airport all the way to the security check on the way out. One way to save yourself some of that stress is to pack light and pack right

Prepare yourself

①     Know the local customs and do a bit of research on your destination to be sure you are at least somewhat familiar with the cultural differences if there are any.

②     Check the weather of your destination. This could change your decisions hugely

③     Call the hotel to find what they offer. Does the room have shampoo, soaps, toothpaste… This can free up some major room in your luggage.

④Make a list on a card with important names and numbers… If you make this as detailed as possible, you will be aware of the time and find things running much smoother.

 

Make a plan

①Make a schedule for your trip with time in a car, a train, a plane

②Make a list of important meetings and how long it will take you to get to them.

③If you are traveling abroad or into a different time zone, try to schedule your meeting at least an hour later and change your watch to local time as soon as you arrive…

 

Make a list and check it twice

①If possible, try and pack a single carry-on bag, so you can quickly leave the airport and move about without noticeably heavy bags.

②The best thing to do is lay out all the clothes you‘think’ you need out on a bed so that you can see them all before you pack them. Then choose the necessities.

③Roll your shirts and skirts, even ties. White shirts should not go on the bottom of your bag, where they could be crushed.

④Fill your shoes with socks to save room…

2、Langston Hughes was born in Joplin, Missouri, in 1902. His parents got divorced. He spent most of his childhood with his grandmother in Lawrence, Kansas. She told him stories about their family and their fight to end slavery. Her storytelling filled him with pride in himself and his race. He first began to write poetry when he was living with her.

In 1919, he moved to Cleveland, Ohio, to stay with his mother. He attended Central High School in Cleveland. Langston was named Class Poet one year. He published his first short stories while still in high school.

Langston Hughes struggled with a feeling of loneliness caused by his parents’ divorce. He developed a love for reading books as a way to deal with the lack of time his parents spent with him. His love for reading grew into a desire to write. He wanted to reproduce the powerful effect other writers, like Walt Whitman, had made upon him.

After graduating from high school in 1920, Langston moved to Mexico City to live with his father for one year. His father did not offer much warmth to him. Yet, Langston turned the pain caused by his family problems into one of his most famous poems,” The Negro Speaks of Rivers.” In this poem, he speaks of the strength and pride of black people in ancient African civilizations and in America.

Langston arrived in New York at 19. Later, he left school, broke with his father, and began traveling. Traveling was a lifelong love that would take him throughout the world before he died.

In 1922, Hughes took a job on a ship and sailed to Africa. He wrote poems and short stories during his travels. His experiences while traveling greatly influenced his work. He sent a few of his writings back home. They were published, and readers found a totally new and fresh style in his poems.
