【题目】下表中所列的是一年中甲、乙、丙、丁四地的昼长差(即一年中昼长最大值与昼长最小值之差)。根据表中的数据回答下列各题。

	甲	乙	丙	丁
昼长差	0	5小时30分	13小时56分	24小时

A. 甲乙丙丁 B. 甲乙丁丙 C. 丁丙乙甲 D. 丁丙甲乙

【2】

A. 10小时25分 B. 8小时35分 C. 9小时15分 D. 14小时45分

【答案】

【1】C

【2】C

【解析】试题分析：

【1】甲地昼长差为0，位于赤道，昼长差最小；丁地昼长差为24小时，位于极圈及其以内地区，昼长差最大；丙和乙位于两者之间．四地所处的纬度从高到低的排列顺序是丁丙乙甲、

【2】昼长差即一年中昼长最大值与最小值之差，用12时减去昼长差的一半，就是昼长的最小值，所以乙地最短昼长是9小时15分，所以C正确。

【题目】根据短文内容，从短文后的选项中选出能填入空白处的最佳选项。选项中有两项为多余选项。

If anyone had told me three years ago that I would be spending most of my weekends camping, I would have laughed heartily. Campers, in my eyes, were people who enjoyed insect bites, ill-cooked meals, and uncomfortable sleeping bags. They had nothing in common with me. 1

The friends who introduced me to camping thought that it meant to be a pioneer. 2 We slept in a tent, cooked over an open fire, and walked a long distance to take the shower and use the bathroom. This brief visit with Mother Nature cost me two days off from work, recovering from a bad case of sunburn and the doctor’s bill for my son’s food poisoning.

I was, nevertheless, talked into going on another fun-filled holiday in the wilderness. 3 Instead, we had a pop-up camper with comfortable beds and an air conditioner. My nature-loving friends had remembered to bring all the necessities of life.

4 We have done a lot of it since. Recently, we bought a twenty-eight-foot travel trailer complete with a bathroom and a built-in TV set. There is a separate bedroom, a modern kitchen with a refrigerator. The trailer even has matching carpet and curtains.

5 It must be true that sooner or later, everyone finds his or her way back to nature. I recommend that you find your way in style.

A. This time there was no tent.

B. Things are going to be improved.

C. The trip they took me on was a rough one.

D. I wasto learn a lot about camping since then, however.

E. I must say that I have certainly come to enjoy camping.

F. After the trip, my family became quite interested in camping.

G. There was no shade as the trees were no more than 3 feet tall.
