解析

【分析】
本题为英语用所给单词适当形式填空题型,解题思路:1. 先确定每个空在句中充当的成分(如宾语、状语、定语等);2. 结合句子时态、固定搭配、词性要求,对所给单词进行变形(如人称代词变反身代词、形容词变副词、动词变过去式等);3. 验证变形后的单词是否符合语法规则与语境。
【解析】
1. 句意:孩子们足够大,离开父母时能照顾自己。look after oneself为固定搭配,表“照顾自己”,they的反身代词是themselves,故填themselves。
2. 句意:很多孩子喜欢炸鸡这类快餐。fried chicken是固定短语“炸鸡”,fry的过去分词作定语表“油炸的”,故填fried。
3. 句意:看!孩子们在那边开心地滑冰。skating是动词,需用副词修饰,happy的副词形式是happily,故填happily。
4. 句意:我做早餐时,用火柴烧到了手。when引导的时间状语从句,主句用一般过去时,burn的过去式为burned/burnt,故填burned(或burnt)。
5. 句意:我扔下包去了客厅。and连接并列动作,后面went为过去式,故throw用过去式threw,填threw。
6. 句意:校车快来了,请快点吃早餐。have breakfast是动词短语,需用副词修饰,quick的副词是quickly,故填quickly。
7. 句意:这节课旨在教孩子们更关注道路安全。road后需接名词,safe的名词形式是safety,故填safety。
8. 句意:汤姆因考试不及格难过地回家。went home是动词短语,需用副词修饰,sad的副词是sadly,故填sadly。
9. 句意:他在操场跑步时突然流鼻血。when引导的从句用一般过去时,bleed的过去式是bled,故填bled。
10. 句意:汤姆从树上摔下来,但幸运的是他没受伤。此处修饰整个句子,需用副词,lucky的副词是luckily,故填luckily。
11. 句意:他昨天病得很重,但现在好多了。ill是形容词,需用副词修饰,bad的副词是badly,故填badly。
12. 句意:长时间看屏幕对眼睛有害。be harmful to是固定搭配,harm的形容词是harmful,故填harmful。
13. 句意:我正在街上走时,一块石头砸到了我的头。when引导的时间状语从句,主句为过去进行时,从句用一般过去时,hit的过去式仍为hit,故填hit。
14. 句意:听到他说的话我很震惊。be shocked to do sth为固定搭配,shock的过去分词作形容词,故填shocked。
15. 句意:史密斯先生仔细检查了机器,但没发现问题。and连接并列动作,后面didn't find为过去式,故check用过去式checked,填checked。

Ⅲ. 阅读理解
When it's sunny and warm, people love to spend time outside. Sadly, spending time outdoors can mean the risk of a bee sting(蜇伤;蜂刺). Most stings are caused by yellow jackets.
Many people are afraid of the honey bee because of its sting. When a bee stings something, it will lose its stinger and die soon. If you leave it alone, it will not hurt you.
To avoid bee stings, shoes should always be worn outside. It is best to wear light-coloured clothing. Bees like bright colours. Children should not play near flowers.
If you or your child gets a sting, there are some things you should do:
1. Look for the sting and take it out.
2. Wash the sting area with running water for 20 minutes.
3. If the sting area still hurts, put ice on it for 10 minutes.
Usually the pain from a sting stops in some hours. The place of the sting may be swollen(肿胀的) for 24 hours. Call a doctor if the place of the sting stays swollen for more than one day or if you have great pain. If a person is stung many times, the person may have a headache or a fever. If the person can't breathe because of the stings, call an ambulance right away.
1. What does the writer suggest the readers do?
A. Wear yellow jackets.
B. Leave the bees alone.
C. Take some sticks.
D. Play in a garden full of flowers.
2. Why should people wear light-coloured clothing outside?
A. To stay cool.
B. To stay away from the butterflies.
C. To stop hurting bees.
D. To avoid bee stings.
3. If the bee stings you, what shouldn't you do?
A. Look for the sting.
B. Wash the sting area with running water.
C. Put ice on the sting area.
D. Call an ambulance at first and wait for help.
4. What can we learn from the passage?
A. Parents shouldn't allow their child to play outside.
B. Clothing with bright colours can help avoid bees.
C. When you get a sting, you must have a headache.
D. Honey bees will die if they sting someone.
5. Whom does the writer write the passage for?
A. Parents.
B. Children.
C. Doctors.
D. Farmers.

【分析】
这是一篇英语阅读理解题,解题思路是先通读全文把握文章主旨(介绍蜂蜇的风险、防护方法及被蜇后的处理措施),再针对每个问题回到原文定位对应信息,逐一比对选项得出答案,重点考查对细节信息的查找与理解能力。
【解析】
1. 细节理解题:根据原文第二段“If you leave it alone, it will not hurt you.”可知,作者建议不要招惹蜜蜂,对应选项B。A选项yellow jackets是蜂种而非衣物;C选项文中未提及;D选项与原文“Children should not play near flowers”相悖,故选B。
2. 细节理解题:根据原文第三段“It is best to wear light-coloured clothing. Bees like bright colours.”可知,穿浅色衣服是因为蜜蜂喜欢亮色,浅色可避免吸引蜜蜂,从而避免蜂蜇,对应选项D。A选项“保持凉爽”文中未提;B选项“远离蝴蝶”无依据;C选项“避免伤害蜜蜂”与文意不符,故选D。
3. 细节理解题:根据原文中被蜇后的处理步骤(找刺取出、流水冲洗、疼痛时敷冰),以及“ If the person can't breathe because of the stings, call an ambulance right away”可知,只有出现无法呼吸的紧急情况才叫救护车,并非首先要做的,选项D是不该做的,故选D。
4. 细节理解题:根据原文第二段“When a bee stings something, it will lose its stinger and die soon.”可知,蜜蜂蜇人后会死亡,对应选项D。A选项与原文“people love to spend time outside”相悖;B选项与“Bees like bright colours”相悖;C选项与“If a person is stung many times, the person may have a headache or a fever”(是多次蜇伤才可能头痛)不符,故选D。
5. 推理判断题:原文多次提到“Children should not play near flowers”“If you or your child gets a sting”,说明作者是写给父母的,对应选项A。B选项孩子是被提醒的对象而非受众;C选项医生、D选项农民均不符合文意,故选A。
【答案】1.B 2.D 3.D 4.D 5.A
【知识点】英语阅读理解、细节理解题、推理判断题
【点评】本文是关于蜂蜇防护的说明文,题目以细节理解题为主,少量推理判断题,整体难度不大,只要能准确定位原文信息即可正确作答,适合中等水平学生完成。
