V、阅读理解
The popular 40-second Superman Ride was the most exciting thing about my trip to Six Flags amusement park in New England!
The ride was the best of the few hours that my friends and I spent there.
We all went on the Superman Ride in pairs. I was with Val. The waiting line seemed never-ending, but was actually only 15 minutes. When it was time for the ride, I felt knots in my stomach and almost changed my mind!
The "drop" of 23 metres looks extremely high. The whole track is more than one mile long. The billboard says that you go 320 kilometres per hour on the ride. People told me it would take longer to climb the hill than the rest of the ride. I was scared to death!
Finally, we got into the car, went uphill for 20 seconds, then heard a sudden big screech. We looked straight down. We saw a faraway track and a small loop. The screeching sound stopped and the car lurched forward. We rushed downhill and off our seats for one second until we got to the loop!
On the loop we were in mid-air most of the time and could hardly see anything. We could have been upside down because people sitting in the car can't tell up from down. Then we rushed through a small tunnel, fell back into the seats and were speeding up another hill. We lurched forward and down like before. After this, the ride was over.
I was so stunned that I could not speak for at least 30 seconds. When I did speak, it was all about the ride!
1. What's the passage mainly about?
A. An amusement park.
B. A school trip.
C. A roller coaster ride.
D. A bus ride.
2. The underlined phrase shows that the author was _____ before the ride began.
A. excited
B. worried
C. surprised
D. amazed
3. Which of the following statements about the ride is NOT true?
A. It runs at a high speed.
B. It goes through a small tunnel.
C. It makes people unable to speak forever.
D. It lasts for 40 seconds.
4. We can tell from the story that _____.
A. the ride is liked by lots of people
B. it costs a large amount of money
C. the author may never go for the ride again
D. the author didn't enjoy the ride at all

重点、难点、考点及疑点注释 1. I don’t think twelve-year-olds should be allowed to get their ears pierced. (P18)我认为不应该允许12岁的孩子穿耳孔。 (1)当主句的主语是第一人称I或we，谓语动词是think, believe, suppose, guess等词时，其后的从句不能是含有not的否定句；若要否定，须将not提到主句。在翻译时，按汉语习惯译作否定从句。例如：“我想他不会给你打电话的”应译为I don’t thi nk he will give you a call而不是I think he won’t give you a call。 特别提示 若把此类句式变成反意疑问句，其助动词及主语要根据从句确定，而肯定/否定则要根据主句来确定。 We think you can help him, can’t you? 我们认为你能帮助他，不是吗？ I don’t think he is a good student, is he? 我认为他不是个好学生，对吗？ (2)本句中的twelve-year-olds相当于twelve-year-old teenagers，意为“12岁的孩子/年轻人”。 知识拓展 数词和一个相应的名词单数用“-”连接起来，可以构成一个合成形容词。常见的还有： two-month holiday 两个月的假期 a sixty-pound stone 一块60磅的石头 (3)get their ears pierced属于“get+名词/代词+动词的过去分词”结构，表示“使……被做”，“请人做……”。 Go and get your hair cut! 你去理理发吧。 Why haven’t you g ot the work done yet? 你为什么还不叫人把活干了呢？ 2. I disagree. (P19) 我不同意。 I agree. (P19) 我同意。 (1) agree意为“赞成，同意”，用来表示同意某人的意见、观点等；可以单独使用，也可以接由with, to, on等引导的介词短语或接从句。 — Shall we go to the zoo tomorrow? 我们明天去动物园，好吗？ — I agree. 我同意。

初中英语中考重难点总结：副词的位置 ①副词修饰动词时，通常可以放在句首、句中或句末。如：Usually I do my homework in the evening. 通常我晚上做家庭作业。I often get up at six. 我常在6点起床。Please speak slowly. 请慢慢说。 注意：频度副词通常置于系动词、情态动词、助动词之后，实义动词之前。例如：Mary is always late for the meeting.?玛丽开会老是迟到。We must always remember our friends.我们必须牢记我们的朋友。？ I have never been to London. 我从未去过伦敦。My mother often does morning exercises in the morning.我妈妈经常在早上做早操。？ ②副词修饰形容词或副词时，通常放在形容词或副词的前面，但也有例外。如：These flowers are quite beautiful. 这些花相当漂亮。He works very hard. 他工作很努力。She is old enough to go to school. 她已到了上学的年龄。 注意： A.副词very 可以修饰形容词，但不能修饰动词。例如：I very like English. I like English very much. B.副词enough应放在所修饰的形容词、副词或动词的后面，形容词enough放在名词前后都可。例如：The boy is old
enough to go to school.这个男孩到上学的年龄了。I know him well enough.我非常了解他。 He didn’t get up early enough to catch the early bus.他起床不够早，没有赶上早班车。 C.注意顺序： quite/rather a good player=a very good player.一个相当不错的球员。 ③按一般规则，如果有几个时间状语，单位大的应放在单位小的后面。如：The film will begin at seven o’clock this evening. 电影今晚7点开演。I was born at two o’clock on the morning of May15. ④按一般规则，既有地点状语又有时间状语时，地点状语应放在时间状语之前。如：We had a meeting in the classroom yesterday afternoon. 我们昨天下午在教室开了一个会。He watched TV at home last night. 他昨晚在家看电视。
