在不考虑其他因素的影响下，如果从赤道以北40千米处出发，依次向正南、正东、正北、正西各走l00千米，最后应位于

A．出发点

B．出发点以北

C．出发点以西

D．出发点以东

答案

答案：D

地球上所有经线的长度相等，不同纬线长度从赤道向两极递减。所以从赤道以北40千米处出发向正南走l00千米，位于赤道以南60千米处，在赤道以南60千米处向正东走100米扩过的经度较大，而在赤道以北40千米向正西走100千米扩过的经度小，所以最终位于出发点的以东。所以本题选择D选项。

单项选择题

My grandfather lived only half a mile away from where I grew up in New York. Every day, he would walk down to our house and bring my dad newspapers. Along with the papers he would bring a small bag of treats for my two brothers and me.

Western NY had terrible winter weather: rain, sleet, or even 3 feet of snow. Even when he was 81, he still walked the half mile every single day. As a child, I looked forward to the daily treats, but now I’m older and I realize he braved the rough weather each day just to see us smile; I now value that more than anything else.

My grandfather touched many lives. A woman who had been in hospital for five years told me her story. She said my grandfather would visit her twice a week at her home: to read to her, play bridge, or just chat. It lasted for years without stop. She had few visitors. Even a hitchhiker who my grandfather had picked up for free told me of my grandfather’s influence on his life. My grandfather took the traveler to his home. After learning that the man was homeless, my grandfather gave him a place to stay. The man told me that no one had ever been so nice to him. He later found a job in a supermarket.

I was touched, but not surprised to know all of the touching stories from which I understood my grandfather’s selflessness. I have since tried to learn from him to help others. Although he died years ago, we still respect him.

All of the following can describe (描述) the writer’s grandfather EXCEPT ().

A．kind

B．selfless

C．strict

D．helpful
