It may not rain，but you had better take an umbrella just in case.)by chance“偶然，碰巧”at large(标语)“(罪犯)逍遥法外的，未被捕获的”;(作后置定语)“大多数的”(如students at large)on occasion“有时，间或”

6. 答案A。agree to sth ：“同意，赞成”(相当于consent to，其宾语可以是极化、办法、措施、方案等名词);agree后面还常跟with/on: agree with sb/sb’ opinion“同意某人的看法”;agree with 另一个常考的意思是“适合于<某人>”，常以食物或天气作主语，(如The weather/Sea food doesn’t agree with me .)agree on “(在某问题上)取得一致意见“;agree with sb. about/on/over sth”在……上同意某人的看法”;不说agree at sth

7. 答案B。in spite of “虽然，尽管;不顾”but for“若不是”(多用于引导一个非真实的条件)for the sake of “为了，为了……的利益，看在……的份上”instead of“而不，作为……的替代”
