题目内容

【题目】12月22日前后,丽丽随父母到国外旅游。她发现正午时这里的人们几乎都没有影子,她去的地方位于(　　)

A.赤道附近B.南回归线附近

C.北回归线附近D.北极圈附近

【答案】B

【解析】

根据当太阳光直射在南回归线上时，这一天称为冬至日，为12月22日，北半球昼短夜长，北极圈以内地区有极夜现象；当太阳光直射在北回归线上时，这一天称为夏至日，为6月22日，北半球昼长夜短，北极圈以内地区有极昼现象；当太阳光第一次直射在赤道上时，这一天称为春分日，为3月21日，全球昼夜平分；第二次直射在赤道上时为秋分日，为9月23日，全球昼夜平分，进行分析解答。

12月22日是北半球的冬至日，此时太阳直射南回归线，这里的人们几乎都没有影子说明该地位于南回归线，此时是太阳直射现象。故选：B。

【题目】You may have heard of the famous saying, "East or West, home is the best.” What does the word "home" mean to you? How do you say the word in French, in Chinese, in your language? Although people usually know what the word means, it sometimes has no exact translation（翻译）. It's not surprising, because the idea of home is different from country to country, and from person to person. A home is more than a roof and four walls. It's the cooking, eating, talking, playing and sleeping that go on inside. And at home you usually feel safe and relaxed.

Homes look different in different countries. They also have different things inside. For example, in cold northern Europe, there's a fire in the living room or kitchen and all the chairs face it. In the south, where the sun shines a lot and it's more important to keep the heat out, there are small windows and cool stone floors.
