2. 答案A.prefer vt .“更喜欢”(常使用的正确句型是：prefer A to B; prefer doing A to doing B; prefer to do A rather than [to] do B;prefer that sb[should] do sth)like和favour两个动词后面都可以跟-ing，但不用like/favour(doing) A to (doing) B句型approve vt .“赞成，同义;批准，核准”

4. 答案B.in case “以防万一，假如”(后面直接跟从句，从句谓语多用一般时态，也可用should/may+原形动词，但不直接用原形动词;美国人常把in case+从句放在句首，表示“如果”，如In case I forget，please remind me about it;但有时in case可以单独用，后面不跟从句，表示“以防出现万一”，如
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”
