解答 此类题型需要被原来的句子由单数变为复数,there be句型中be动词的单复数取决于后面名词的单复数.首先要注意把there is变为there are,然后把表示单数的a peach,a knife等变为some peaches,some knives等,然后再把句子其他的部分加上即可.
故答案为
43.There are some peaches on the table.
44.There are some knives near that tin.
45.There are some policemen in the kitchen.
46.There are some cups on the shelf.
47.There are some tomatoes on the table.

点评 对于句型转换的题目要分析原句的句型结构,并找出同义句型或者相同意思的表达方式,或者使用非谓语动词的形式,或者从句的形式以及一些特殊句式等,要根据句式结构特点进行灵活选择.

6.Since the 1990s,education has been required for all South Africans from age seven to fifteen.Last December,the government announced that seventy percent of students passed their final examination to finish high school.In 2008 the passage rate was about sixty-three percent.There have been increases each year since then.
Professor Shireen Motala at the University of Johannesburg says that access to basic education is no longer the problem in South Africa.She says most children stay in school until they are about sixteen.The problem now,she says,is that large numbers of them leave without completing high school.
Students take an examination known as the matric in grade twelve,their final or"matriculation"year.Professor Motala notes that less than half the children who started school in 2000 sat for the matric last year.
Educational researchers also point to another problem.They say South African schools do not produce enough students with the skills for higher education in math and science.Many schools are not well-equipped.They do not have libraries at school.Ninety-two percent of the schools do not have libraries.
Also,education specialists say,in many cases,teachers and school principals do not have the skills or training to do their jobs.In other cases,they are simply not doing their duty to provide an education.
Professor Motala says a number of teachers were poorly trained during the system of apartheid (种族隔离制度),or racial separation in South Africa.Apartheid ended in 1994.
Secondly,she says,teachers have been confused by the many educational reform efforts in the last fifteen years.And,finally,she thinks language differences in the classroom have not gotten as much attention as they should.
South Africa's minister of basic education promises a number of improvements.
41.What does the underlined word"passage"most probably mean?D
A.Leave school                        
B.Receive education.
C.Take exams.
D.Pass the exam.
42.What's Motala's attitude towards the basic education for students in South Africa?A
A.Confident.B.Hopeless.C.Negative.D.Worried.
43.Form the passage we know the matric isB.
A.an examination difficult for students to pass
B.an examination for students in grade twelve
C.the number of students leaving school
D.the number of students taking exams
44.Students in South Africa find it hard to get improved in math and science becauseC.
A.they drop out of school without finishing high school
B.teachers don't have the abilities to teach them
C.most schools can not provide enough equipment
D.there aren't such subjects in most schools
45.In which section of a newspaper can you most probably see the passage?C
A.Entertainment.B.News report.C.Education.D.Lifesty.
