Pretoria．South Africa—Hundreds 0f swimmers Play in the water along a South African beach．Suddenly a huge shark appears offshore and heads for the bathers．Before it can get close to the swimmers，the shark，for some mysterious reason，starts swimming parallel to the beach．Then it turns away from shore and heads out to sea，leaving the swimmers untouched．
Such a scene will soon become common along shark infested（鲨鱼出没）shores．An electrical engineer from the University of Pretoria has developed an electrical system that repels（击退）sharks by controlling their movements．Confused by this action，the sharks end up turning away from the beach．
In this unusual shark repellent method，an insulated（绝缘）cable is buried on the bottom of the sea around a beach from which people swim．When an electric current is sent though the cable，an electric field is produced in the water above the cable．
When the shark swims into the electric field，nerve cells just below the shark’s skin detect the field．The electricity produces a reflex（反射）action in the shark’s muscles，causing the dangerous animal with sharp teeth to swim parallel to the cable．Contused by increasing loss of control of its muscles，the shark suddenly changes its direction and heads seaward，away from the electric field．
In a test of the invisible new shark-repellent system，a cable was placed around a beach in St．Lucia an island in the tropics．A protective net，which had been installed around the beach a long time ago to keep sharks from swimmers，was left in place during the experiment．
When the electric field was 1eft on for more than a year and a half，no sharks were found in the nets．However,when the power was turned off，89 sharks ended up in the nets．
Using the electric wall method instead of nets to protect bathers would avoid the needless death of many sharks，say biologists．Currently，thousands of sharks die each year when they become trapped in protective nets that surround holiday resorts in Africa and Australia．About 10 to 15 humans are killed by sharks annually．
1.In the first passage，why doesn’t the shark attack the swimmers？
A．Because they are many swimmers in the water．
B．Because the shark doesn’t want to eat the swimmers。
C．Because of some mysterious reason from the God．
D．Because there is an invisible electric field confusing the shark．
2.An electrical engineer from the University of Pretoria has developed________．
A．A protective net B．A new shark-repellent system
C．The electric field D．An insulated cable
3.An electric field is produced in the water above the cable ________．
A．only when the shark swims into the electric field
B．an insulated cable is buried on the bottom of the sea around a beach from which people
swim
C．only when an electric current is sent though the cable
D．only when the sharks are trapped in protective nets
4.Which of the following is NOT TRUE according to the passage?
A．Protective nets had been installed around the beach earlier than the new shark repellent system．
B．This new kind of shark repellent system wilt take place of the protective nets．
C．Thousands of sharks die and about 10 to 15 humans are killed by sharks each year in Africa and Australia since this new system was Put into use．
D．Using the electric wall method instead of nets to protect bathers would avoid the needless death of many sharks．

During the 1800s, African Americans worked long days in the fields of the American South．To ease their labor, they sang "field hollers" that they had brought from Africa．One person sang a line．Then a group of workers repeated it．The songs' words told of the hardships that people suffered．African Americans sang "shout spirituals", or joyous religious songs．They clapped their hands and stomped their feet to the music．
After the Civil War, the music changed dramatically．African American music, from ballads to church music, took new forms．It also adapted dance music, called "jump-ups"．which had great rhythm． Banjos became popular．A blues singer usually played a call and response with the banjo．By the early 1900s, the guitar had replaced the banjo as the main blues instrument．
Northern Mississippi - called the Delta - was the center of the blues tradition．By the 1920s, the Delta had many clubs, so-called juke joints．African Americans listened and danced to music in these clubs．Some of the greatest blues men and women performed there．
Blues have a soulful sound that is easy to recognize．The musical notes are often "bent"．That is, they are changed slightly to give a song more strength．Whatever their origin, these bent notes most often define the blues．
Lyrics are the words of a song．Blues lyrics describe everyday life．The lyrics, often about relationships between men and women, are often very intense and personal．They tell about sorrow and overwork．They tell about finding or losing love, having money or being broke, being happy or sad and lonely．The lyrics may use humor to describe life's trials and joys．They almost always use the rhythms of everyday speech．A typical blues stanza, or group of lyrics, has three lines．The second line repeats the first line．The third line has different words．
By the 1940s, large numbers of African Americans had left the Delta and moved north to work． Many settled in Chicago．There, a new kind of "electric", or "Chicago" blues began．Many of its themes were the same, but these blues had "wailing" electric guitars and harmonicas．The music had a steady, strong drumbeat．The loud, driving Chicago blues was excellent dance music．Chicago blues led to the birth of a new music style-rock and roll．
1.The "field holler" is a kind of music that came from ___．
A．the American South． B．Africa．
C．Chicago． D．Asia．
2."Shout spirituals" and "field hollers" are similar in that both_____．

C．included call and response singing． D．expressed sadness．
3.A typical blues Stanza is made up of____．
A．three lines． B．a harmonica．
C．a driving beat． D．four lines．
4.One can conclude from the passage that the blues ___．
A．would have widespread without the juke joints of the Mississippi．
B．served as a form of communication and self-expression．
C．was successful only in the American South．
D．there were only greatest blues man performed in these clubs．
5.African Americans probably moved to Chicago because ____．
