She has just lost her mother. Her pink clothes are full of blood and her eyes look at something only she can see. Every day we see pictures like this on our televisions. We see Iraqi (伊拉克的) children begging for food and water from American and British soldiers as they move through towns and cities towards the capital, Baghdad. We see these children following parents, carrying bags of almost the same size as their small bodies as they escape from their homes in Baghdad. They show just some of the young lives that have been turned upside down by ongoing war and the terrible price paid by Iraqi children. "Dad, why are the Americans fighting against us? Are we going to be killed? " asks the son of Abu Singar, an Iraqi engineer. Abu finds it hard to explain this war to his eight-year-old son. He tries to make him feel safe by saying, "The bombs (炸弹) are far away from us. The Americans are fighting the soldiers. We're going to be all right." Even though Abu knows it isn't always true, little else can be done. In Baghdad, parents give their children sleeping pills to try and let them escape from the sound of bombs. And all the schools are closed. Now things are worse, and the ongoing war makes it impossible to count the number who are hungry, sick, hurt or even dead. 1.What happens to the children in Iraq because of the war? The children ______. A. will live a better life than before B. beg for food and water from soldiers. C. go away from their homes in Baghdad D. live a most terrible life because of the war 2.What does the underlined word "ongoing" mean in Chinese? A. 正在进行的 B. 即将结束的 C. 未授权的 D. 影响恶劣的 3.The father doesn't tell the true thing to his child because he ______. A. wants to make his child not feel dangerous B. and his child are afraid to lose each other in the war C. doesn't want his child to believe American soldiers D. will lose his country and his home if he tells the truth 4.The war in Iraq tells us that ______. A. American soldiers are actually helping the Iraqi people B. many Iraqi people in the war don't have enough food C. nothing can be done except fighting a war this way D. it was only soldiers who are suffering from the war 5.What would be the best title for the report? A. Iraqi Children during the War B. Sickness, Death in Iraq C. America and England Fight against Iraq D. A Girl in the War in Iraq 【答案】1.D, 2.A, 3.A， 4.B, 5.A 【导语】文章通过电视画面展现伊拉克战争中儿童的悲惨处境：4 岁女孩失去母亲、浑身是血；儿童向美英士兵乞讨食物和水，跟随父母背着与身体差不多大的行李逃离巴格达。战争打乱了伊拉克儿童的生活，阿布・辛格这位伊拉克工程师难以向 8 岁儿子解释战争，只能谎称安全；巴格达的父母给孩子吃安眠药以躲避炸弹声，学校也全部关闭。目前战争仍在持续，饥饿、生病、受伤甚至死亡的儿童数量已无法统计。 【详解】1答案：D 解析：文章提到伊拉克儿童 “失去母亲、浑身是血”“乞讨食物水”“逃离家园”“吃安眠药躲炸弹声”“无法上学”，整体是 “因战争过着极其悲惨的生活”。A 选项 “生活更好” 与原文完全相反；B、C 选项仅是悲惨处境的一部分，并非全部（如还有 “失去亲人、无法上学” 等），D 选项更全面概括，故选 D。 2.答案：A 解析：后文提到 “Now things are worse（现在情况更糟）”“makes it impossible to count（无法统计）”，说明战争 “仍在继续”，“ongoing” 意为 “正在进行的”。B（即将结束）与 “情况更糟、无法统计” 矛盾；C（未授权）、D（影响恶劣）均未体现 “持续进行” 的核心含义，故选 A。 3.答案：A 解析：原文提到阿布 “tries to make him feel safe by saying...（试图通过撒谎让儿子感到安全）”，可见不告诉真相的目的是 “不让儿子感到危险”。B 选项 “害怕失去彼此” 无依据（原文未提 “害怕分离”）；C 选项 “不想让儿子信士兵” 无依据（谎言是关于 “炸弹远、安全”，非 “不信士兵”）；D 选项 “说真相会失去国家家园” 无依据，故选 A。 4.答案：B 解析：原文明确提到 “we see Iraqi children begging for food and water（看到伊拉克儿童乞讨食物和水）”，可推断 “战争中很多伊拉克人没有足够食物”。A 选项 “美军帮助伊拉克人” 与 “儿童乞讨、逃离家园” 矛盾；C 选项 “除了打仗别无他法” 无依据（原文未提 “解决方式”）；D 选项 “只有士兵受苦” 错误（原文重点讲儿童受苦，还有父母等普通人），故选 B。 5.答案：A 解析：文章全程围绕 “伊拉克战争中的儿童” 展开，从具体画面（女孩、乞讨儿童）到生活现状（躲炸弹、失学），核心主题是 “战争中的伊拉克儿童”。B 选项 “伊拉克的疾病与死亡” 范围过广（未聚焦 “儿童”）；C 选项 “美英攻打伊拉克” 仅为背景（未讲 “儿童”）；D 选项 “战争中的一个女孩” 仅为开头例子（不全面），故选 A。 试卷第1页，共3页 原创精品资源学科网独家享有版权，侵权必究！ 学科网（北京）股份有限公司 $ 编写说明：2026版吉林省（高职分类考试）《英语考点双析卷》，依据最新版《中等职业学校英语课程标准》及历年高考真题进行编写。“考点双析”即围绕一个考点，一份是老师的讲解卷，一份是学生的练习卷，共涵盖20个考点的68份试卷，助力师生构建 “讲练结合” 的学习闭环，特别适用于第一轮高考复习。 本卷是2026版吉林省（对口招生）《英语考点双析卷》的第20卷，主要考形容词句法功能。 2026版吉林省（对口招生）《英语考点双析卷》第20卷 形容词句法功能 学生练习卷 一、单项选择（共30小题每题3分，共90分） 从每题所给的A、B、C和D四个选项中，选出最佳选项。 1.My grandmother told me a ______ legend about the mountain near our hometown.
