2018海淀九年级英语一模命题分析+试卷解析
2018 初三海淀英语一模题分析+试卷解析亲爱的同学们以及家长们，海淀一模英语学科已经拉下帷幕。
为了帮助大家更好地备战中考、了解中考、赢在中考，高思初中英语的老师们在第一时间为大家做了命题分析和试卷解析，希望大家能够以此为起点，再次飞跃、突破，实现中考英语高分，甚至是满分的目标！总体分析一、单项填空2018 年单项填空再次“大改革”，虽然分值降低，但是题目增多，意味着 2014年的“完整 13 个语言点”基本“重现”。
这一部分主要是对考生词汇用法和语法知识的综合考察。
需要有扎实的词汇和语法基础。
单项填空看似简单，尤其在分值降低后，考生容易忽略这一部分的“满分”。
但是，今年海淀一模给大家敲响警钟：单选并没有简单到“一眼得分”的程度。
在保证考点“不超纲”的前提下，2018 年中考仍在持续不断地求“变”和求“新”。
本次海淀一模没有“逃”出常考基础词汇和语法知识点的范畴：代词、介词、特殊疑问词、连词、形容词/副词比较级最高级、情态动词、时态、语态、宾语从句。
其中时态和语态的考察依旧占比较大，尤其是现在完成时，每年必考。
现在完成时在八年级下学期校内会进行讲解，学生如果练习、理解不到位，很容易出错。
高思初三英语高效学习班会进行单项填空的专项训练，根据考点一一练习。
在春季课程中，我们又通过一套套的实战训练卷进行训练，通过这样的强化练习和讲解，考生们会在这一题型大大增高正确率，拿下满分。
二、完形填空2018 年完形填空也有改革，题量以及分值都有所降低，这对于考生们来说应该是一个“好消息”。
但考点依旧着重实词和上下文理解的考察。
主要考察的几大词性为：动词、名词、形容词和副词。
今年海淀一模的完形填空考查题材依旧为故事类记叙文，非常贴近日常生活，并注重引导学生践行积极向上的价值观，感恩父母、关爱老人。
考生们在日常备考练习过程中要多多注意找准完形填空的主线和中心思想，以此为突破口来解题。
此篇完形填空相对来说，内容比较简单，但是文本里有诸多固定搭配、习惯表达和地道用语，并且，依旧存在一词多义的现象和实词辨析的题目，特别考验学生平时积累的“基本功”。

Possible version:题目一Dear Tom,I am very happy to know that you won the first prize in the Chinese speech competition, so I’m writing to congratulate you on your wonderful performance.You did a good job in the Chinese speech competition. You pronounced really well during your speech and your voice was beautiful. You spoke so fluently that we all felt proud of you. What’s more, we were surprised at your rich and meaningful contents.As your best friend, I know you tried your best for the competition. You kept practicing your speech every day in order to make it better. I know it is important to keep on trying and never to give up. I hope I can be successful like you one day in the future.Yours,Li Hua 题目二It’s very important to be confident. Self-confidence can bring us courage to stick to what we do. So it’s valuable to us.When I was in Grade 7, once my teacher asked me to make a speech in class. Although I practiced it for many times at home, I still felt nervous and forgot the words at the beginning of it. Then I breathed deeply and relaxed myself. You can’t believe how happy I was when I recalled the speech and finished it successfully. My teacher thought highly of my performance and I got much encouragement from my classmates. From then on, I have become more and more confident.To build confidence, firstly we need to clearly know about our own advantages and try to develop them. It is the most important that we should put in enough effort to what we do.Then we can finally make it and gain more confidence.1。

Lyle’s Second GoIn 1982，when I was coaching the Raiders，the owner of the team talked with me about a possible trade for Lyle Alzado. After watching him on tape，I didn’t think he was that good, but the owner felt we could make Lyle better by creating the right environment lor him. We made the 13 .That summer at training camp，Lyle was having a hard time. He had that look in his eyes that many young players and some old players get when things aren’t going 14. One morning Lyle came into my office and he looked like he hadn’t slept. Here was a huge man, with his head about as 15 as it could go. We talked, or rather, I listened. The main point was that Lyle felt his career (职业生涯）was over and it would be best for him and for the team if he retired (退役）.He apologized for 16 us since we had just traded for him.Lyle was always an emotional person. This is one of the reasons he was a good player. He 17 all that emotional energy with him, ready to lire out at the snap of the ball (开球）.Now he was in front of me，almost crying. I thought for a moment，realizing we had to keep that 18 going. Then I went through my reasons why he should not retire. At the end of our talk，I said，“You go out and play your very best, and let us 19 if you still have it. Personally，I think you do.”In January 1984. Tampa Bay Stadium. Super Bowl XVIII. With less than two minutes remaining, we were leading 38-9. We were the world champions of professional football. I saw Lyle，crying like a baby. I had to turn away quickly，or I would have joined him in 20.I remembered that morning in my office，and what Lyle，and what the Raiders，had achieved since he came to us. If Lyle hadn’t given his career another shot, he wouldn’t have had this victory. Maybe the Raiders wouldn’t have had this victory. During that moment，I felt one of the greatest satisfactions of my coaching career.13. A. deal B. plan C. argument D. mistake14. A. away B. over C. well D. fast15. A. low B. cool C. clear D. heavy16.

I thought I 16 my parents’ feelings because I could see the disappointment on their faces and I was sure they could see it on mine.

December 24, 2010, I decidedto 13 a little last-minute shopping before joining my family at my mother’s.I bought a large basket of cheeses and a bottle of wine. On my way down, the elevator (电梯) stopped at the third floor, where everybody but an older couple and me got off – and where a tall, handsome man 14 . We started down again; then suddenly, the elevator stopped. We were stuck – on Christmas Eve!15 there was a phone, and the old man called someone in maintenance (维修), whotold us that we had to be in for a long wait.At that point, we – the older couple, Mr. and Mrs. Philips; John, the handsome man; and I– sat down on the floor and began 16 Christmas memories. An hour passed, then two; we found ourselves so involved in the conversation that we forgot we were stuck. I shared my basket of cheeses and wine with them. I didn’t realize at the time we were creating another special Christmas 17 .After five hours, the elevator finally moved. When the doors opened, the worried store manager was surprised to find us in such 18 spirits. Saying our good-byes, the four of us exchanged addresses and promised to send holiday greetings to each other in the years to come.I got to my mother’s for our traditional family Christmas – a bit late, 19 I got there. Christmas evening I returned to my apartment. Waiting for me was a single red rose and a message: I really miss the cheese basket, John. At the bottom was his phone number…John and I were married the following Christmas Eve. And we are 20 exchangingChristmas greetings with Mr. and Mrs. Phillips. And I still wake up every Christmas Eve morning filled with excitement at the magic of the day.13. A. make B. do C. show D. accept14. A. got up B. got down C. got off D. got on15. A. Sadly B.
