That the denial of one member of two words implies the asser

正确答案：A
题干的意思是：“要成为大学教师需要有博士学位。”本题考查不定式短语(To become)作状语表示行为的目的或结果。Become是动词原形，不能直接引导表语作状语；One becomes与其后的成分已经构成一个完整的句子后面应该用句号，但原句后用逗号致使全句成为连写句(错句)；One becoming是分词短语，分词短语作状语表示主语正在进行的另一动作。

参考答案：
Upon graduation, virtually all college students will confront the problem of the career choice，which is truly a tough choice.Students'' opinions differ greatly on this issue.Some hold that priority should be given to take a job, but others take the attitude that going to a graduate school is the most critical factor influencing their future career choices.
As to myself, I prefer the latter view.A higher educational background exerts a tremendous fascination on a great number of people, with no exception to me.This phenomenon that the graduates have difficulties in finding job after their graduation can easily be found anywhere in our daily life, especially on campus.On the one hand, with the improved high education of Chinese college students which directly brought the result that there are more and more graduates every year.On the contrary, job vacancies don’t increase that fast.More people, less food, which is the exact deion of the hard condition.On the other hand, more and more people go on to pursue their master and doctor degree; more and more Chinese oversea students come back to China to hunt better working chances.It is sure that the competition is more and more fierce.
Therefore, it is high time that we took effective measures to improve our own competitiveness.That is the secret of success in the future employment market after our graduation.

答案：

优点：assert 作用是如果它的条件返回错误，则终止程序执行。

缺点：使用 assert 的缺点是频繁的调用会极大的影响程序的性能，增加额外的开销。

解析：

ASSERT()是一个调试程序时经常使用的宏，在程序运行时它计算括号内的表达式，如果表达式为FALSE (0), 程序将报告错误，并终止执行。如果表达式不为0，则继续执行后面的语句。这个宏通常原来判断程序中是否出现了明显非法的数据，如果出现了终止程序以免导致严重后果，同时也便于查找错误。

参考答案：Upon graduation, virtually all college students will confront the problem of the career choice，which is truly a tough choice.Students'' opinions differ greatly on this issue.Some hold that priority should be given to start a business of your own, but others take the attitude that finding a job is the best choice influencing their future.
As to myself, I prefer the latter view.An opportunity to start a business exerts a tremendous fascination on a great number of people, with no exception to me.In my view, With the competition in the job market becoming increasingly fierce for college graduates， some ambitious students have tried their hands at launching their own businesses.Over the years，there have been many successful cases of student entrepreneurship and such attempts should be encouraged and promoted by both the universities and the society at large.What’s more ,College students who start businesses are pioneers，among whom will be born China’s future business leaders.Faced with unknown challenges， they are audacious enough to embark on a perilous journey while most of their peers enjoy stable salaries by working as white-collars at high-end office buildings.
All in all, the essential difference between the students who find a job or those students who create their own businesses is that the former are docile followers whereas the latter are aggressive trailblazers.For this reason， business-launching college graduates are more admirable， and thus they command our deep respect.
