本题考查自然地理环境的地域分异规律。

自然地理环境从赤道到两极、从沿海向内陆及垂直地带的地域分异规律。

分异规律形成基础影响因素分布规律
从赤道向两极热量太阳辐射沿纬线延伸，经度更替
从沿海向内陆水分海陆分布沿经度延伸，纬线更替
山地的垂直分异热量，水分海拔高度从山麓到山顶有规律的变化
干湿度地带分异规律就是从沿海向内陆的地域分异规律。其影响因素是水分。所以本题选择A选项。

单项选择题

A punctual person is in the habit of doing a thing at the proper time and is never late in keeping an appointment.
The unpunctual man, on one hand, never does what he has to do at the proper time. He is always in a hurry and in the end loses both time and his good name. A lost thing may be found again, but lost time can never be regained. Time is more valuable than material things. In fact, time is life itself. The unpunctual man is for ever wasting and mismanaging his most valuable asset as well as other’s. The unpunctual person is always complaining that he finds no time to answer letters, or return calls or keep appointments promptly. But the man who really has a great deal to do is very careful of his time and seldom complains of want of it. He knows that he can not get through his huge amount of work unless he faithfully keeps every piece of work when it has to be attended to.
Failure to be punctual in keeping one’s appointments is the sign of disrespect towards others. If a person is invited to dinner and arrives later than the appointed time, he keeps all the other guests waiting for him. Usually this will be regarded as a great disrespect to the host and all other guests present.
Unpunctuality, moreover, is very harmful when it comes to do one’s duty, whether public or private. Imagine how it would be if those who are put in charge of important tasks failed to be at their proper place at the appointed time. A man who is known to be habitually unpunctual is never trusted by his friends or fellow men.

According to the passage, the main reason that a person is always unpunctual is that ______.

A. he has more work to do than other people
B. he is always in a hurry when he works
C. he doesn’t care much about time
D. he always mismanages and wastes his time
