[填空题]Schools looking to ban cell phones may have a new excuse: a growing number of people are developing an allergy (过敏) to metal in the devices. We all know that food allergies are on the rise—a study last year placed the rate at 1 per 70 children, compared with 1 in 250 in the 1970s. But at last month’s meeting of the American College of Allergy, Asthma & Immunology, allergists reported that many substances that once seemed harmless are now leading to allergic reactions too.
Allergies can develop when young bodies come into contact with a new substance, and an increasing number of kids have early exposure to tech tools and "adult" products that can lead to a lifetime of reactions. For instance, the nickel hardware often used on phone trim and faceplates can lead to red, itchy (发痒的) skin where the phone is pressed against the face of someone who developed a nickel allergy at a young age. It’s especially problematic for women, says Luz Fonacier, an allergist who presented at the conf

[简答题]Cell phones may help busy executives keep in constant touch with important business associates, but they may also increase their risk of high blood pressure, preliminary research suggests. A study of 10 German mobile phone users found that when they switched on their phone, their blood pressure shot up by 5 to 10 millimeters of mercury, researchers reported in this week’s issue of the international medical journal, The Lancet. Exactly how cell-phone use can lead to increases in blood pressure is unclear, but researchers speculate that the electromagnetic fields emitted by phones may somehow boost pressure. While the blood pressure increases found in the new study are small, they may be detrimental to people who already suffer from hypertension, researchers led by S. Braune of the Neurologische Universitateklinik in Freiburg, Germany, explained.

Cell phones are a danger on the road in more ways than one. Two new studies show that talking on the phone while traveling, whether you’re driving or on foot is increasing both pedestrian deaths and those of drivers and passengers, and recommend crackdowns on cell use by both pedestrians and drivers.
The new studies, lead-authored by Rutgers University, Newark, Economics Professor Peter D Loeb, relate the impact of cell phones on accident fatalities to the number of cell phones in use, showing that the current increase in deaths resulting from cell phone use follows a period when cell phones actually helped to reduce pedestrian and traffic fatalities. However, this reduction in fatalities disappeared once the numbers of phones in use reached a "critical mass" of 100 million, the study found.
These studies looked at cell phone use and motor vehicle accidents from 1975 through 20
A. show that talking on the phone while driving or walking in the street increases deaths of drivers and pedestrians
B. show that talking on the phone while driving increases pedestrian deaths
C. recommend that strict measures be taken to restrain cell phone use
D. both A and C
