【题目】Hightech glasses developed at Washington University School of Medicine in St. Louis may help surgeons visualize cancer cells, which glow blue when viewed through the eyewear. Cancer cells are notoriously difficult to see, even under highpowered magnification. The glasses are designed to make it easier for surgeons to distinguish cancer cells from healthy cells, helping to ensure that no tumor cells are left behind during surgery.

Were in the early stages of this technology, and more development and testing will be done, but were certainly encouraged by the potential benefits to patients, said breast surgeon Julie Margenthaler, MD, an associate professor of surgery at Washington University. “Imagine what it would mean if these glasses got rid of the need for followup surgery and the associated pain, inconvenience and anxiety.”

Current standard of care requires surgeons to remove the tumor and some neighboring tissue that may or may not include cancer cells. The samples are sent to a pathology(病理) lab and viewed under a microscope. If cancer cells are found in neighboring tissue, a second surgery is often recommended to remove additional tissue that is also checked for the presence of cancer.

The glasses could reduce the need for additional surgical procedures and following stress on patients, as well as time and expense.

Margenthaler said about 20 to 25 percent of breast cancer patients who have lumps removed require a second surgery because current technology doesn’t adequately show the extent of the disease during the first operation.“Our hope is that this new technology will reduce or ideally eliminate the need for a second surgery, she said.

In a study published in the Journal of Biomedical Optics, researchers noted that tumors as small as 1 mm in diameter (the thickness of about 10 sheets of paper) could be detected.

Ryan Fields, MD, a Washington University assistant professor of surgery and surgeon of Alvin J. Siteman Cancer Center, plans to wear the glasses later this month when he operates to remove a melanoma from a patient. He said he welcomes the new technology, which theoretically could be used to visualize any type or cancer.

A limitation of surgery is that its not always clear to the naked eye the distinction between normal tissue and cancerous tissue, Fields said.With the glasses developed by Samuel Achilefu, PhD, professor of Washington University, we can better identify the tissue that must be removed.”

【题目】Public Speaking Training

·Get a coach

【1】 , so get help. Since there are about a billion companies out there all ready to offer you public speaking training and courses, here are some things to look for when deciding the training that's right for you.

·Focus on positives

Any training you do to become more effective at public speaking should always focus on the positive aspects of what you already do well. Nothing can hurt confidence more than being told that you aren't doing well. 2 , so good public speaking training should develop those instead of telling you what you shouldn't do.

3 If you find a public speaking course that looks as though it's going to give you lots of dos and don't walk away! Your brain is so full of what you're going to be talking about. 4 . As far as we're concerned, there are basically no hard and fast rules about public speaking. Your audience can be your friends.

You are a special person not a clone.Most importantly, good public speaking training should treat you as a special one, with your own personal habits. 5 . Your training course should help you bring out your personality, not try to turn you into someone you're not.

A. You aren't like anybody else

B. You already do lots of things well

C. Turn your back on too many rules

D. Check the rules about dos and don't

E. Whatever the presentation, public speaking is tough

F .The one thing you don't want is for them to fall asleep

G. So trying to force a whole set of rules into it will just make things worse

【题目】Erica Wills admits an addiction left her poor and almost ruined her life. But it wasnt drink or drugs. The 21-year-old former model was addicted to exercise. . Erica only realized she had become a gym addict when she decided to take a night off to celebrate her 21st birthday.

I wasted a whole year of my life doing nothing but exercise,” she says. . “ I thought we’d see more of each other if we worked out together.” When that relationship ended, she fell in love with the thrill of keeping her body in tip-top condition.

Every evening, I left the insurance company where I worked and dashed off to the club,” says Erica. “ But not me. All I would do is rushing off to the gym for five-hour sessions. I went through the lot each night—aerobics, a weights circuit in the gym, then a swim. I would get home after 11 pm, have something to eat and fall into bed. It was the same every weekday. On Saturdays, I might spend even longer in the gym.”

I just poured all my money into the gym. Membership and classes came to around 100 a month, plus I had to buy clothing and equipment.

I didn’t realize I had lost all my friends until my 21st birthday came round. I decided to take one evening off to go out with them. Then someone told me I hadn’t been a very good friend for a year, so why should anyone bother turning up? In fact, just one girlfriend came with me for a drink on my 21st birthday. That was the turning point for me. I cut right down on the gym and tried to pick up where I had left off with people.”

A. I didn’t buy anything else all year—I couldn’t afford to.

B. I first went to a health club when I dated a bodybuilder.

C. I only went out with my friends two or three times a week.

D. Anyone else aged 20 would be out with friends, having a laugh.

E. But when I started calling people, everyone said they couldn’t make it.

F. My old girlfriends were beauty queens and dancers, and I am naturally competitive.

G. Her hobby turned into a year of aerobic hell as she spent all her spare time in the gym.

【题目】Not being the greatest fan in the world of live performance, I took a deep breath before I en tered the building, the castle theatre, and prepared myself to be bored, expecting to find it more interesting to watch the audience than the show. Then I got the shock of my life.

Wadaiko Inchiro are a group of ten young Japanese men and women using traditional drums with a history going back more than 1500 years. The drums were once used for festivals and religious ceremonies and also as a means of communication during wars. Today they give an ear-blasting performance which punches out rhythms with the power to wind you. They’re a welcome relief from the Scottish pipers.

Unlike other performances, the best seats are at the back of the house. Not only will your ears be protected from full blast, but you will get a fantastic view of the whole set. On stage are some of the biggest drums you will ever see and a cast wearing red, white and black headscarf.

There had been almost no publicity for the show, but the house was full of people desperate, one could only assume, for something a bit different from the unrelenting performances appearing at this world-famous festival. The solid 60-minutes show starts as it means to go on. The drums rumble into fever-pitch action as the ten-strong company strike their sticks with startling control. Their rhythmic frenzy almost immediately drugs you into submission. Trapped inside the beating of the drums, you carried swiftly through warrior war cries to emotional rhapsodies(狂想曲). Not only is this display musically impressive, but the dance is strikingly beautiful. Moving between the enormity(巨大)of the drums, the slight Japanese characters have complete synchronicity(同步性)with the flying of their sticks, which they ceremonially cross and use to command.

The biggest drum is played only by Inchiro, the leader of the group. When I ask why this is so, he refuses to admit that he is being precious about this monster of an instrument and says, “When someone else can play it as I do, I will happily move aside.” Dressed all in red, he stands before it as thought he is worshipping at an altar; as he raises his sticks to the drum, he touches it sometimes tenderly and sometimes murderously. Inchiro and his drum produce a range of sounds from thunder to the trickle of rain.
