根据短文内容,从短文后的选项中选出能填入空白处的最佳选项,选项中有两项为多余选项。

 小题1: 

Today,kids have more worries and face more pressures than ever before. Here are a few tips to help your child focus on and do well in school.

●Create a personal schedule

Recording everything that must be done on a calendar or “to do” list will help him to keep track of important dates and deadlines. If he keeps it in a visible place he will have no problem acknowledging upcoming events and will be better able to plan how and where to spend his time.

●Watch the clock

 小题2:  I also recommend setting his clock or watch five minutes ahead since it's always easy to run late. When it comes to something like catching a bus,just five minutes can make a significant difference.

●Focus

He should train himself to be able to concentrate alone on one specific task. This is much easier in a noise­free environment. No TV or radio should be on to distract him.

 小题3: 

Lack of sleep is proven to harm us physically. The more sleep we get,the more alert we are. We thus have more energy to handle life's daily tasks. The average adult needs at least six hours of sleep a night and the average child needs at least eight.

●Stay in shape

Through spending time outdoors or playing sports with friends,he can “blow off some steam” so to speak,as well as re­energize. 小题4: 

●Talk through your problems

Be able to share his concerns with you.  小题5:  If you make it clear that you understand him and are willing to help,not only will you contribute to his emotional health but you'll help build an open and honest relationship as well.

A.Sharing feelings often makes them easier to deal with.

B.Help your child work better to realize his aim.

C.Setting an alarm for the morning is a must.

D.Get enough sleep.E.Help your child do better in school.

F.Encourage your child to be positive.

G.Encourage him to get outside.

答案

小题1:E

小题2:C

小题3:D

小题4:G

小题5:A

题目分析:现在的孩子面临着比以前的孩子更多的问题,所以在本文中给出了建议,告诉孩子如何处理这些问题。让孩子做得更好。

小题1:E 本文讲述的是现在的孩子面临着比以前的孩子更多的问题,所以在本文中给出了建议,告诉孩子如何处理这些问题。让孩子做得更好。故E项正确。

小题2:C 根据下一句I also recommend setting his clock or watch five minutes ahead说明是建议孩子们设一个闹钟,故C项正确。

小题3:D 根据本段第一句Lack of sleep is proven to harm us physically.说明缺少睡眠的危害,那么就是建议我们要有充足的睡眠,故D项正确。

小题4:G 根据本段第一句Through spending time outdoors or playing sports with friends说明要鼓励孩子多倒户外运动,故G项正确。

小题5:A 根据本段标题和第一句Talk through your problems Be able to share his concerns with you.说明通过与孩子交流然孩子的事情更好处理。故A项符合上下文。

点评:做题时要注意文章的首段和每一段的首句或尾句,因为它们往往就是文章的主题句。阅读中要注意要点之间的关系。

单项选择题
实验题

八年级的晓明同学曾经在实验室窗外看到化学老师做过这样的实验:用一种固体跟一种液体在不加任何条件的情况下接触即可发生化学反应,并且生成一种无色的气体。你也已经学了一年的化学,相信你能帮助晓明解决疑惑。请进实验室!

【走进实验室】下列仪器可供选择并且能按具体实验要求配套使用:

【提出问题】固体是什么?液体是什么?生成的气体是什么?如何检验呢?

【猜想与假设】可能是常见的氢气或氧气或者二氧化碳。

【查阅资料】氧气、氢气、二氧化碳都可以由固体与液体直接接触反应制得。

【实验设计】(1)请给晓明介绍三种仪器的名称________、_____、________(已标注的除外)。

(2)请帮助晓明组装一套固体与液体接触制取并收集二氧化碳的装置:制取时用________,收集时用________(用仪器编号填空,无先后顺序)。

(3)请选出实验室用排水集气法收集氧气所用的仪器编号(无先后顺序)___________。

【实验探究】【实验结论】氧气、氢气、二氧化碳都可以用固体与液体直接接触反应制得。

【拓展与应用】(4)经过学习和探究你认为设计实验可以不必考虑的因素是____________。

A.反应物的性质与状态 B.反应条件与反应原理 C.所制得气体的用途 D.所制得气体的性质及验证方法

(5)实验室验证二氧化碳时未见浑浊,试分析造成此现象的可能原因:__________(写出一条即可)。
