It 11 (lie) in the northwest of Guanghan, Sichuan Province. Sanxingdui is such 12 amazing place that it is now world-famous. Archaeologists have been working there since 1934. Many people before me put in a great deal of 13 (effort). As I continued their work, I often felt like I was standing on the shoulders of giants. The finds at Sanxingdui provide a missing piece of Chinese history. Sanxingdui was a centre of different cultures. This 14 (prove) that Chinese culture was open from a very early period. Different cultures mixed with each other to form today’s China. Sanxingdui is such a wonderful place that people visit from all over the world. For me, this is something more valuable than the gold masks in our museum. It means that more people are interested in our discoveries. We’re able to open a door to the past so that people 15 (can) better understand the history of our country. The treasures are so beautiful that they come alive in my imagination. People in the ancient Shu Kingdom were so creative that we are amazed by their works. Over the past 40 years, I have never felt bored with my work in this magical place. I keep imagining the lives of these ancient people. Although we have found a large number of things at Sanxingdui, we are far from 16 (get) the whole picture of the Shu culture. There are so many questions 17 (be) dug into. But success never comes smoothly. Archaeologists do not believe in luck. We believe in hard work. We will work even harder so that people know more about our wonderful past. Bit by bit, we will be able to bring out the secrets of our history. The work is 18 (difficulty), but the result is satisfying. Every new discovery makes me feel 19 (excite). I hope more young people will join us and become 20 (interest) in archaeology. 1 / 12 学科网（北京）股份有限公司 $ Unit 1 Life choices 核心语法精练 （时态与情态动词） 目录 二、考点夯基 3 一、用所给单词的正确形式填空 3 二、单项选择 4 三、完成句子 7 四、句型转换 8 一、语法选择 9 二、短文填空 11 时态 一、用所给单词的适当形式填空。 1．She has already ________ (learn) that she is what she is. 【答案】learned/learnt 【解析】句意：她已经认识到她就是她自己。句中“has”为助动词，与“already”共同构成现在完成时的标志，其后应接动词的过去分词形式。“learn”的过去分词有两种形式：“learnt”和“learned”，两种均可接受。 2．Workers ________ (print) thousands of pages last week. 【答案】printed 【解析】句意：工人们上周印刷了成千上万张纸。时间状语“last week”提示句子应用一般过去时，print过去式直接加ed，故填printed。 3．When the river ________ (reach) the village, it becomes wide and clear for people to swim in. 【答案】reaches 【解析】句意：当河水到达村庄时，变得宽阔而清澈，人们可以在此游泳。本句时态是一般现在时，主语是“the river”，动词用三单。 4．We e________ phone numbers before we said goodbye to each other. 【答案】exchanged/xchanged 【解析】句意：我们分别时交换了电话号码。根据首字母提示和“We…phone numbers”可知，是交换号码，exchange“交换”符合语境；根据“before we said goodbye to each other”可知，动作发生在过去，用一般过去时，动词用过去式exchanged。 5．Many people in that area are ________ ________ (遭受) serious illnesses. 【答案】 suffering from 【解析】句意：那个地区许多人正遭受重病的折磨。根据中文提示“遭受”，对应初中英语常用短语suffer from。句中有be动词are，且表示目前的状态，应用现在进行时，结构为be+动词现在分词。动词suffer需变为现在分词suffering，介词from照写。故填suffering；from。 6．If it ________ (happen) tomorrow, we won’t have a picnic in the park. 【答案】happens 【解析】句意：如果明天发生，我们就不会去公园野餐了。本句是if引导的条件状语从句，主句“we won’t have a picnic”是一般将来时，从句主语it是第三人称单数，因此谓语动词happen要变为第三人称单数形式happens。 7．Look!

(改为被动语态) The old should _________ _________ good care of. 【答案】 be taken 【解析】句意：我们应该照顾好老年人。句子含有情态动词should“应该”，因此被动语态是含有情态动词should的句子，结构为should be done；take的过去分词是taken。故填be；taken。 13．(25-26九上·重庆大学城第一中校·月考)You can read faster by reading word groups. (对划线部分提问) ______ ______ you read faster? 【答案】 How can 【解析】句意：你可以通过读词组来读得更快。划线部分为“by reading word groups”，这里是提问方式，用疑问词how来提问，原句含有情态动词can，在疑问句中情态动词要提前到主语前面。故填How；can。 14．(25-26九上·上海杨浦控江集团·)He considered the problem for a long time but couldn’t find a solution. (保持句意基本不变) He considered the problem for a long time but couldn’t ________ ________ ________ a solution. 【答案】 come up with 【解析】句意：他思考这个问题很久，但找不到解决方法。原句中“find a solution”意为“找到解决方法”，可用同义短语“come up with a solution”替代，表示“想出解决方法”，且情态动词couldn’t后接动词原形。故填come；up；with。 15．(25-26九上·黑龙江齐齐哈尔铁锋区齐齐哈尔第二十九中学和第四十五中学·月考)We should protect red-crowned cranes because they are endangered.

The finds at Sanxingdui provide a missing piece of Chinese history. Sanxingdui was a centre of different cultures. This 14 (prove) that Chinese culture was open from a very early period.
