As it turns out, they did. As reported last month in the American Journal of Psychiatry, 23 of the 30 people who were part of the study reported feeling significantly less depressed after the scan. The most dramatic improvements were among those who were taking no medication. The researchers are cautious. Says Bruce Cohen, McLean's president and psychiatrist in chief: “I want to emphasize that we are not saying this is the answer but this is a completely different approach in trying to help the brain than anything that was done before."
It's a completely different approach because of the way the magnetism is applied to the brain. But it's an example of new research on an old idea: that the brain is an electromagnetic organ and that brain disorders might result from disorder in magnetic function. The idea has huge appeal to psychiatrists and patients alike, since for many people the side effects of psychiatric (精神的) drugs are almost as difficult to manage as the disease itself. And 30 percent of the nearly 18.8 million people who suffer from depression do not respond to any of the antidepressants available now. People with other severe mental disorders might benefit as well. And while no one fully understands exactly why or how the brain responds as it does to electrical currents and magnetic waves, fascinating new research is offering some possible explanations.

Passage Four
My kids tell me that I am "so 20th century", which troubles me. A person likes to feel that he is "with it", as we used to say in the 20th century.
So I have been thinking how I might change myself into a true 21st-century man. Clearly, in my advanced state of age I would be foolish to attempt some wild leap into the contemporary fashion. And anyway, my distinctive taste attracts much favourable comment.
But if my clothing is too characteristic to change, perhaps I should do something about my lifestyle. So last week I took myself to the NEC for the Smart Home Show which is "the exhibition dedicated to all the latest trends in smart
18
home technology".
It was a shock. How could I have lived for half a century without a fingerprint-operated front door? ("Never lock yourself out of your home again!") Or vacuum cleaners that suck dust straight into a dustbin, via a system of pipes in your house walls? (All you have to do is rebuild your entire home.) Or automatic garden sprinklers which are so smart that they turn themselves off when it starts to rain? Of course, you could just look out of the window, observe that it's raining and turn them off yourself, but that would be so 20th century.
Besides, those were just the simpler things. For the true smart-home owner, a plasma (等离子) TV fireplace is a must. At first glance it's just an electric fire with a mantelpiece，but press your remote and a giant TV screen rises from the mantelpiece. "Thieves won't even know it's there," a spokesman claimed. Just as well. At ￡5,280，it would be a pity to have it broken. But the real revolution has happened in the bathroom. Never again need you feel cut off from world events as you go about your washing. Forget the mirrors that turn into TV screens. They're old hat. The buzz in bathrooms now is all about heated towel-racks that turn into TVs.
Enough! I was convinced: I want a smart home. There's only one problem: The cost. You are looking at ￡18,000 to ￡25,000 for an average home. Hmm. I won't be entering the 21st century just yet, then.
69. To be "21st century", the author decided to___________.
A. move to a new house
B. change the way he lived
C. improve his dressing style
D. talk in the most trendy fashion
70. The author's comment on the vacuum cleaner implies that___________.
A. he believed that it was useless
B. he wanted to purchase one himself
C. he hated to cause inconvenience
D. he thought that it was not worth the effort
71. What is the most revolutionary smart home technology according to the author?
A. The plasma TV fireplace.
B. The automatic garden sprinkler.
C. Mirrors that turn into TV screens.
D. Heated towel-racks that turn into TVs.
72. The Smart Home Show__________.
A. seemed too good to be true
B. was a true eye-opener for the author
C. left a negative impression on the author
D. appealed less to the middle- and old-aged
73. What does the author think of buying the smart home products?
A. He was interested, but found them too expensive.
B. He was fascinated, and determined to buy them.
C. He wasn't attracted, and wouldn't buy them.
D. He wasn't sure, so he would rather wait and see.
74. Which of the following words could best describe the author's tone?
A. Overstated.
B. Objective.
C. Ironic.
D. Passionate.
Passage Five
Never before has flying been so controversial. In the space of two years, the environmental damage done by planes has gone from being something quietly discussed by scientists and committed environmentalists, to a headline-grabbing issue no one can ignore.
Even those who fly once or twice a year on holiday can't help but feel a growing sense of guilt, while those opting for trips by car, train or ferry have a self-righteous spring in their steps.
Now, however, the backlash is beginning. The tourism and aviation industries are mobilizing, and pointing out some awkward facts. Did you know that some ferries emit far more carbon dioxide than some planes'? That driving can release twice as much carbon as flying? A new report from Balpa, the pilot's union, even claims that planes can be better than train.
While there are the campaigners who plot their camp at Heathrow to protest the air travel, in Kenya plans are being drawn up for a very different camp. Looking out from a cliff over the deserts of Samburuland is a stunning hotel, the O1 Malo Eco-Lodge. Revenue from the small number of visiting tourists has allowed the 5,000 acres around it to be transformed from over-grazed cattle ranch to a conservation site. More impressive still is the O1 Malo eye project. Up to 80 per cent of adults in the area suffer sight loss, so the O1 Malo Trust runs regular surgical camps, bringing doctors from the UK to treat them. In January, the camp gave 102 people back their sight. "It's very simple--all of our visitors fly here," said Julia Francombe, the founder. "If they stopped coming, it would kill us."
One thing on which all sides agree is that aviation is booming, so it becomes crucial to develop new and less polluting aircraft. Airbus's claim that it can save the world with the A380 may be far-fetched, but its "gentle giant" plane is far more efficient and quieter than those of 20 years ago.
Some environmentalists, however, scorn these advances, saying such measures are a "delusion." "The aviation industry is likely to vastly overstate the gains that can be made from technological improvements but sadly a climate friendly plane isn't on the horizon," says Emily Armistead of Greenpeace.
So the question is: who do you believe?
75. Pollution caused by planes used to _____________.
