1．The UN weather agency warned on Tuesday there was a good chance of an"El Nino"climate phenomenon in the Pacific Ocean this year，bringing droughts（干旱） and heavy rainfall to the rest of the world The World Meteorological （气象的） Organization （WMO） said its modeling suggested a"fairly large potential for an El Nino，most likely by the end of the second quarter of 2016"．
The El Nino phenomenon occurs every two to seven years，when the trade winds that circulate surface water in the tropical （熟带的） Pacific start to weaken．
WMO pointed out Tuesday that since last December，trade winds had weakened and there had been a significant warming of the waters below the surface in the central Pacific．
"While there is no guarantee this situation will lead to an El Nino event，the longer the trade winds remain weakened，and subsurface temperatures stay significantly warmer than average，the higher chances are，"it said．
Two thirds of climate models predicted that the phenomenon would begin sometime between June and August，with one-fifth suggesting it could start as early as May，and the remaining predicting no El Nino this year，it said．
It is often followed by a return swing of La Nina，which is characterized by unusually cool ocean surface temperatures in the central and eastern tropical Pacific．
"El Nino has an important warming effect on global average temperatures，"Jarraud cautioned，stressing that combined with warming from greenhouse gases such events had"the potential to cause a sharp rise in global average temperature"．
33．It can be inferred from the first two paragraphs thatB-'
A．a weather agency warned an"El Nino"would appear on Tuesday
B．WMO showed an El Nino would probably happen by June in 2016
C．an El Nino would bring heavy rainfall to the Pacific Ocean
D．The phenomenon of El Nino happens every seven years
34．What does the underlined phrase"this situation"in Paragraph 4refer to？A
A．Cool ocean surface temperatures in the central and eastern tropical Pacific．
B．A significant warming of the waters below the surface in the central Pacific．
C．Trade winds that circulate surface water in the Pacific．
D．Heavy rainfall in different areas all over the world．
35．According to the text，what might be the percentage of no"El Nino"this year？D
A.13%． B.20%． C.67%． D.87%．

10．While contact between adolescents （between the ages of fifteen and nineteen） and their peers （同龄人） is a universal characteristic of all cultures，the nature and the degree of such contact vary a great deal．In American contemporary society，adolescents spend much more time with their peers than with younger children or adults．
This pattern of age segregation（隔离） in American society did not become usual until the beginning of the industrialized society．Changes in the workplace separated children from adults，with adults working and children attending school．The dramatic increase of mothers in the workplace has further contributed to the reduction in the amount of time adolescents spend with adults．School reform efforts during the nineteenth century，which resulted in age-segregated schools and grades，have reduced the amount of time adolescents spend with younger children．Finally，the changes in population are considered a factor that may have contributed to the emergence of adolescent peer culture．From 1955 to 1975，the adolescent population increased dramatically，from 11 percent to 20.9 percent．This increase in the number of adolescents might be a contributing factor to the increase in adolescent peer culture in terms of growth in size．
Research supports the view that adolescents spend a great deal of time with their peers．Reed Larson and his colleagues examined adolescents'daily activities and found that they spend more time talking to their friends than engaging in any other activity．In a typical week，high school students will spend twice as much time with their peers as with adults．This gradual withdrawal from adults begins in early adolescence．In sixth grade，adults （excluding parents） account for only 25 percent of adolescent social networks．Another important characteristic of adolescent peer culture is its increasingly autonomous （自治的） function．While childhood peer groups are conducted under the close supervision of parents，adolescent peer groups typically make an effort to escape adult supervision and usually succeed in doing so．

（Note：Answer t．he quesnons or complete the statements in NO MORE THAN EIGHT WORDS．）
81．"This pattern of age segregation"refers to the phenomenon that adolescents segregate themselves fromyounger children and adults
82．Besides changes in the workplace，school reform efforts and the changes in populationare the other two factors contributing to adolescent peer culture．
83．When do adolescents start to spend less time with adults？In early adolescence．
84．How do adolescent peer groups differ from childhood peer groups？They have less close supervision of parents．/They manage to escape adult supervision．/They are increasingly autonomous．．
