Maria 和 Lily 是双胞胎 因为:(思路)David 比 Jone 小两岁 所以David只能是10岁或9岁,如果David 10岁,那么Jone 就是12岁。 同理Lily 9岁 Jane 11岁,这样只剩下Maria 和10岁了。 但是Maria 比David 大, 显然不符,所以假设不成立,那么David 就是9岁,用同样的推理就能知道 Maria 和 Lily都是10岁,是...

Well, Mrs. Evans, I’ve done my best to look after David. I’v

Well, Mrs. Evans, I’ve done my best to look after David. I’ve tidied his room up every day, got him a meal together whenever he needed one and made sure he’s always had a clean shirt to put on. It’s not been easy, with two of my own to worry about, as well. David had the best of attention, I must say. But now because I asked him to give up bringing that American friend to his home he has got quite miserable and unfriendly. He comes in at all hours and his behavior---- well, it’s quite hard to put up with---- and it’s all because of this friend. I’m sure he’s a bad influence. You see, David’s a visitor and doesn’t fully understand our ways.
He used to study most evenings. He’s got through quite a bit of work. He did up his room quite nicely, with bookshelves and large posters. He’d ask Mr. Smith and me up for a drink and cheer us up with songs from his country. He’s very good at the guitar, you know.
I don’t want to appear as if I’m running after him, but it’s about time we made it up. I’m sure he’s upset because I told him off. It might be a good idea to take him out for a meal, perhaps even with his friend. I don’t know whether it will do any good but we can try. I’m glad I’ve had this little chat with you, Mrs. Evans, and I’ll let you know how I get on.
1. Mrs. Smith believes that David is not the cause of the quarrel but that the main cause is __________.
A. Mr. Smith B. too much homework
C. David’s behavior D. David’s friend
2. Mrs. Smith wants to make up the quarrel by _______.
A. cooking a meal B. inviting David and his friend out
C. running after David D. giving them drinks
3. David’s present attitude to Mrs. Smith is ________.
A. unfriendly B. cheerful C. very attentive D. incomprehensible
4. David is ________.
A. an American friend B. a singer C. a visiting student D. Mrs. Smith’s son

B
首先 根据意思排除选项C
接下来辨析and和with:
and 连词,连接两个并列的词、词组或者句子,表示“而”、“和”、“又”等之意.and所连接的前后两个词在各个方面都处于平等的地位,当其连接两个词或词组时,这两个词或词组在句中的作用是相同的,即充当同一个成分.故当其连接两个词时,这两个词的形式应相同.如:
My father is a teacher ,and my mother is a worker.我爸爸是一名教师,而我妈妈是一名工人.
My brother and I like swimming.我的弟弟和我都喜欢游泳.(I不可用me,因为I和my brother都在句中作主语)
with为一个介词,其后必须跟名词或代词作其宾语,表示“和……一起”“跟”和……一道等之意.故其后跟人称代词时应用其宾格形式.如:
Mr Green’s children are with their father in China .格林先生的孩子们和他们的父亲来到了中国.
