For reasons of safety and ease of maintenance, Washington and dozens of other communities are building rubber sidewalks made 76 ground-up tires of cars and bikes. The rubber squares are up to three times more expensive than concrete squares but 77 longer, because tree roots and freezing weather won't crack them. That, 78 , could reduce the number of slip-and-fall complaints made 79 uneven pavements.

A major new study shows that the situation may be changing. A large and rapid drop in the world's birth rate has taken place during the past 10 years. Families generally are smaller now than they were a few years ago. It is happening in both developing and industrial nations.
Researchers said they found a number of reasons for this. More men and women are waiting longer to get married and are using birth control devices and methods to prevent or delay pregnancy. More women are going to school or working at jobs away from their homes instead of having children. And more governments, especially in developing nations, now support family planning programs to reduce population growth. China is one of the nations that has made great progress in reducing its population growth.
China has already cut its rate of population growth by about one half since 1970. China now urges each family to have no more than one child. And it hopes to reach zero population growth, the number of births equaling the number of deaths, by the year 2000.
Several nations in Europe already have fewer births than deaths. Experts said that these nations could face a serious shortage of workers in the future. And the persons who are working could face much higher taxes to help support the growing number of retired people.
In the sentence "Experts long have been concerned about such growth" of Paragraph 1, the phrase "concerned about" is similar in meaning to ______.
A．worried about
B．related to
C．engaged in
D．made a study of
Researchers from Yale and the University of Connecticut followed 600 middle-schoolstudents as they developed from fifth to seventh grade, nothing their weight and if they had zerobreakfast, breakfast either at home or at school, or breakfast in both places. They found thatweight gain among second-breakfast eaters was no different from the average gain seen amongall students. Children who didn ’t eat breakfast, or ate it only sometimes, were more likely to beoverweight than double-breakfasters. It should be noted that only about one in ten children inthe study ate two breakfasts.
The study wasn’t designed to figure out why this might be true, but the researchers havesome theories: that people who don ’t eat breakfast (or any meal) might overeat later in the day,and that as people become obese, they tend to reduce calories （热量） by having no breakfast.
Yes, school breakfasts are more like a healthy snack（零食） than a full meal, and growingteens can eat a large amount of food. But if you ’re still not eating breakfast because you think itgives you more colories, you are not only mistaken, but you are also missing out one of life ’s greatpleasures.
What do we know about the research according to Paragraph 1？
A.It was about the effect of dinner on weight gain.
B.Its result was opposite to the author’s opinion.
C.It was done on overweight school children.

Heart failure, for example, appears to have seasonal and temporal patterns. A higher percentage of heart attacks occur in cold weather, and more people experience heart failure on Monday than on any other day of the week. In addition, people are more susceptible to heart attacks in the first few hours after waking. Cardiologists first observed this morning phenomenon in the mid-1980, and have since discovered a number of possible causes. An early-morning rise in blood pressure, heart rate, and concentration of heart stimulating hormones, plus a reduction of blood flow to the heart, may all contribute to the higher incidence of heart attacks between the hours of 8:00 AM and 10:00 AM.
In other studies, both birthdays and bachelorhood have been implicated as risk factors. Statistics reveal that heart attack rates increase significantly for both females and males in the few days immediately preceding and following their birthdays. And unmarried men are more at risk for heart attacks than their married counterparts. Though stress is thought to be linked in some way to all of the aforementioned risk factors, intense research continues in the hope of further comprehending why and how heart failure is triggered.
What does the passage mainly discuss？
A．Risk factors in heart attacks.
B．Seasonal and temporal patterns of heart attacks.
C．Cardiology in the 1980s.
D．Diet and stress as factors in heart attacks.
