Some people seem to lose all their energy and drive, wanting only to sleep. Others react in exactly the opposite way. Becoming so over energized that they can't find enough activity to burn off their excess energy. For instance, one woman said she cleaned out all her closets completely and was ready to go next to start on her neighbor's. Both these extremes, however, eventually, the symptoms may be intense for two or three days, but within 10 to 14 days after quitting, most subside (平静下来). The truth is that after people quit smoking, they have more energy, they generally will need less sleep, and feel better about themselves.
Quitting smoking not only extends the ex-smoker's life. but adds new happiness and meaning to one's current life. Most smokers state that immediately after they quit smoking, they start noticing dramatic differences in their overall health and vitality.

Which of the following is the main psychological symptom of smokers who quit？ ______.
A．Being light-headed
B．Being anxious
C．Being easily annoyed

A decade of intense civil rights activity was launched in 1954 when the United States Supreme Court declared segregated schools to be unconstitutional. In 1955, Dr. Martin Luther King, Jr. , effectively organized the Blacks of Atlanta, Georgia, in a bus boycott. The boycott lasted two years, and when it was over, Blacks no longer were degraded by being forced to sit or stand in the rear of buses.
In 1960, a group of Black college students decided that they, sis well as white persons, had the right to eat at a lunch counter in Greensboro, North Carolina. This sit-in sparked an aggressive national movement and, in the next few years, thousands of young men and women -- Black and white, North and South -- overturned local laws and customs that had maintained segregation. Sit-ins, prayins, freedom rides, freedom marches and demonstrations to open all schools to Black children took place across the nation.
Several important actions took place to change the status of black people ______.
A．after World War Ⅱ
B．in 1954
C．before 1945
D．in 1960
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.
Which of the following may be regarded as potential crises？
A．An alarming rise in local housing prices
