2. how to surf
3. Welcome back to
4. having great fun
5. send to
6. taking a boat along; my first time seeing
7. make good progress

2.根据“but she knows how to surf in the sea”可知前后转折，前面应该是不知道如何在网上冲浪，“how to surf”符合语境。
3.根据“It's great to see you all again after the summer vacation.”可知是欢迎大家回到学校，“Welcome back to”符合语境。
4.根据“Ms Li is teaching us how to cook cookies”可知大家应该很开心，“having great fun”符合语境。
5.根据“writing a post card”及“my best friend in London”可知应该是寄给朋友，“send to”符合语境。
6.根据“Yi River”可知应该是乘船沿着沂河，“taking a boat along”符合语境；根据“such beautiful sights in Linyi”可知应该是第一次看到，“my first time seeing”符合语境。

由于您没有提供教材69页的短文内容，我无法直接回答这些问题。请您提供短文的具体内容，以便我按照七年级下册Section B的语法和知识点（通常涉及现在进行时、描述活动、天气、感受等）进行解答。
如果您能提供短文文本，我将按照以下步骤为您解答：
1. 针对每个问题，在短文中定位相关信息。
2. 根据现在进行时（be+doing）的结构提取关键动词短语。
3. 确保回答符合问题要求（如地点、活动、感受等），语言简洁准确。
请您补充短文内容后，我会为您提供详细的解析和答案。
