C.比R地收获早—季风环流

D.比R地收获晚—地势高低

答案

小题1:B  

小题2:B  

小题3:A

题目分析:

小题1:甘肃省和冀鲁豫位暖温带,两年三熟;湖北省位于长江以北,一年两熟。综上所述,只有B符合。

小题2:纬度高低和地形是影响农作物收获的主要因素。M和R都位于平原地区,因此影响图中M、R两地收获日期差异的主要因素就看纬度高低(热量)了,A正确。

小题3:N为四川盆地,R为长江中下游平原,四川盆地比较封闭,加上周围高山的阻挡,导致冬夏季均温比同纬度地区高,冬小麦成熟时间早,收获早。因此只有A项正确。

     In the past, people who graduated from college felt proud of their academic (学业的) achievements and

confident that their degree would help them to find a good job.   

     However, in the past four years the job market has changed greatly. This year's college graduates are

facing one of the worst job markets. For example, Ryan Stewart, a graduate of San Jose State University,

got a degree in religious studies, but he has not gotten any job offers. He points out that many people already

working are getting laid off and don't have jobs, so it's even harder for new college graduates to find jobs.   

     Four years ago, the future looked bright for his class of 2006. There were many high-tech ("dot com")

job opportunities, graduates received many job offers, and they were able to get jobs with high salaries and

benefits such as health insurance and paid vacations. However,"Times have changed. It's a new market,"

according to an officer of the university.   

     The officer says students who do find jobs started preparing two years ago. They worked during summer

vacations, they have had several short-time jobs, and they majored in fields that are still paying well, such as

accounting or nursing.   

     Even teaching is not a secure profession now. Ryan Stewart wanted to be a teacher. But instead he will

probably go back to school in order to become a college teacher. He thinks college teaching could be a good

career even in a bad economy.   

     In conclusion, these days a college degree does not automatically lead to a good job with a high salary.

Some students can only hope that the value of their degree will increase in the future.

D. It would help them to start an academic career.

2. Why does Ryan Stewart want to be a college teacher?   

A. Teaching jobs are well-paid.  

B. He majored in teaching in the university.   

C. College teaching is less challenging than high-tech jobs.   

D. College teaching career won't be influenced by economy.
