答案与解析　D　本题考查与过去事实相反的虚拟语气。虚拟条件句动词用“had＋动词的过去分词形式”，主句用“would＋have＋过去分词”形式。

— I agree, but the problem is ________ he has refused to.
A. will not be sent; that
B. not be sent; that
C. should not be sent; what
D. should not send; what
答案与解析　B　由于necessary后面的从句要用“(should＋)动词原形”，排解选项A；由于he与send是被动关系，排解D项；答句中的表语从句中不缺任何句子成分，用that，故选B项。值得说明的是， refused to后省略了be sent to New York。
Ⅱ.阅读理解
A

A study of English learning problems was carried out among a total of 106 foreign students. It shows that most students considered understanding spoken English to be their biggest problem on arrival. This was followed by speaking. Writing increased as a problem as students discovered difficulties in writing papers that they were now expected to hand in. Reading remained as a significant (显著的) problem.
The information gained helped us in determining where special attention should be paid in our course. Although many students have chosen to join the course with a reasonable motivation (动机), we considered it important to note what seemed to encourage interest. Nearly all the students have experienced some kind of grammar­based English teaching in their own country. To use the same method would be selfdefeating because it might reduce motivation, especially if it has failed in the past. Therefore a different method may help because it is different.
A variety of activity was also seen as a way of maintaining (保持) or increasing motivation. Several years ago we had one timetable that operated throughout, but we soon found that both the students and the teachers lost interest by about halfway through the ten weeks. This led us to a major rethink, so finally we brought it into line with the expressed language needs of the students.
1. What is the text mainly about?
A. Foreign students have more problems.
B. There are many ways to improve English.
C. Teaching should meet students' needs.
D. English learning problems should be studied again.
答案与解析　C　主旨大意归纳题。由首段所阐述的同学学习英语面临的困难，到其次段首句及文章最终一句表达的含义推知，英语教学应满足同学的需要。
2. Writing became a bigger problem when foreign students ________.
A. had to write their papers
B. became better at speaking
C. became less interested in reading
D. had fewer problems with listening
答案与解析　A　细节理解题。文章的第一段第四句话“Writing increased as a problem as students discovered difficulties in writing papers that they were now expected to hand in.”可知。
3．We may infer from the last two paragraphs that ________.
A. different teaching methods should be used
B. grammar­based teaching seems to be encouraging
C. English courses are necessary for foreign students
D. teaching content should be changed halfway
答案与解析　A　细节推断题。依据为其次段最终一句“Therefore a different method may help because it is different.”和最终一段中的反面例子。
4. The underlined word “it” in the last paragraph refers to ________.
A. rethink B. activity
C. motivation D. timetable
答案与解析　D　推断代词指代题。依据本段其次句“Several years ago we had one timetable that operated throughout”及本句“This led us to a major rethink”推知。
B
Learning Later in Life

It's often said that we learn things at the wrong time. University students frequently (经常) do the minimum amount of work because they're crazy for a good social life instead. Children who often scream before their piano practice because it's so boring, have to be given gold stars and medals to be persuaded to swim, or have to be bribed (赐予嘉奖) to take exams. But when you're older? Ah, now that's a different story.
Over the years, I've done my share of adult learning. At 30 I went to a college and did courses in History and English. It was an amazing experience. For starters, I was paying, so there was no reason to be late — I was the one frowning (皱眉) and drumming my fingers if the teacher was delayed, not the other way round. Indeed, if I could persuade him to linger,_it was a prize, not a trouble. I wasn't frightened to ask questions and homework was a pleasure not a pain. When I passed, I had passed for me and me alone, not my parents or my teachers. The satisfaction I got was entirely personal.
Some people fear going back to school because they worry that their brains have got slow. But the joy is that, although some parts have been dull sometimes, your brain has learnt all kinds of other things since you were young. It's learnt to think independently and flexibly and is much better at relating one thing to another.What you lose in the dull department, you gain in the maturity (成熟) department.
In some ways, age is a positive plus. For instance, when you're older, you get more self­controlled. Experience has told you that, if you're calm and simply do something carefully again and again, at last you'll get the hang of it. The confidence you have in other areas — for example, being able to drive a car, perhaps — means that if you can't, say, build a chair immediately, you don't, like a child, want to destroy your first pitiful attempts (尝试). Maturity tells you that you will, with application, eventually get there.
5．What surprised the writer when she did her first adult learning course?
A. She got on better with her tutor.
B. She was able to learn more quickly.
C. She had a more relaxed attitude to it.
D. She found learning more enjoyable.
答案与解析　D　推理推断题。文章其次段由“It was an amazing experience”一句引出了作者吃惊的缘由。由紧跟其后的描述可知，缘由在于作者发觉学习更加令人开心了。
6．The writer says that when you learn later in life, you will find ________.
A. it boring to take lessons
B. it hard to remember things easily
C. it hard to give all your attention to study
D. it different to learn from when you were younger
答案与解析　D　推理推断题。由第三段其次、三句可知，虽然年长的时候有些方面会变得迟钝，但年长者在学习时更能够独立思考，机敏应变，将此事与彼事联系起来，这些与年轻的时候是不同的。
7．According to the writer, what's the advantage of adult learners?
A．They are able to organize themselves better than younger people.
B. They are less worried about succeeding than younger people.
C. They pay more attention to details than younger people.
D. They have more patience than younger people.
答案与解析　A　推理推断题。最终一段叙述了年长者在学习中的优势，由其次、三句可知，他们能更好地自制，能够利用阅历更好地掌控自己。
8. What is the writer's main purpose in the article?
A. To emphasize the pleasures of adult learning.
B. To point out how easy adult learning can be.
C. To explain her reasons for doing adult learning.
D. To describe the teaching methods used in adult learning.
答案与解析　A　推理推断题。文中作者通过叙述自己的学习经受，指出成人后再进行学习是有其独特的优势，并且乐趣多多的。
9. What does the underlined word “linger” in Paragraph 2 probably mean?
A. go back B. delay going
C. teach them more D. end classes on time
答案与解析　B　词义猜想题。依据年轻同学的心理，老师上课迟到是再好不过的了，所以作者认为假如他能说服老师晚走，那是一种嘉奖，并非麻烦。此处linger意为“连续逗留”。
