Choose a good topic sentence to begin each of the following paragraphs.
1.
A. My new neighborhood is an ideal place to live.

It’s a very safe neighborhood and I am not afraid to go out alone at night. In addition, the neighborhood is in a very convenient location. Lots of stores, restaurants and schools are nearby. Within walking distance, there is also a library and a movie theatre. Most of all, I really like the people who live in this neighborhood. They are friendly and helpful.
2.
A. Would you prefer to travel alone or travel in a group?
B. Travelling in a group is superior to travelling alone in many aspects.
In any travel there might be risks, such as unexpected hurt by wild animals, rocks and floods, or there might be other emergencies such as diseases or accidents. On such occasions friends may give immediate help. However, if you are travelling alone, such immediate help would be impossible. In addition, being with friends may add extra pleasure to the travel. They can share your loneliness, talking with you about the sights whereas you may feel lonely and bored when travelling alone.

【分析】
选择主题句需先明确段落核心内容，主题句要概括段落主旨，需符合陈述观点的特点，不能仅说明事实或为问句。第1题段落围绕新社区的安全、便利、邻里友好等优点展开，核心是强调新社区适合居住；第2题段落围绕结伴旅行的优势展开，核心是表达结伴旅行优于独自旅行的观点。
【解析】
1. 分析段落内容：该段落从安全、地理位置便利、邻里友好三个方面介绍新社区的优势，核心是强调新社区适合居住。A选项“我的新社区是理想的居住地”准确概括了段落主旨；B选项仅说明“我最近搬到了新社区”，未体现段落的核心优势，因此选A。
2. 分析段落内容：该段落从遇到紧急情况能获得帮助、结伴旅行更快乐两个方面，阐述结伴旅行比独自旅行更好的观点。B选项“结伴旅行在很多方面优于独自旅行”是明确的观点句，符合主题句要求；A选项是疑问句，不能作为主题句，因此选B。
