小明等四名同学以“寻找常温下能加速过氧化氢分解的物质.并通过实验比较它们的效果”为课题开展研究,请就他们活动中的一些问题回答:

(1)在讨论研究计划时的下列观点,你认为不正确的是______

A.小明认为可以通过图书馆查找相关资料

B.小红认为可以到厦门大学请教专家,得到他们的指导

C.小华认为可以上网查找相关资料

D.小东认为不需要查找资料,只要进行实验就可完成本研究

(2)经过初步研究,他们选定了五种物质进行两两对比实验.下列实验组不可能为相应的猜想提供证据的是______

组别ABCD
猜想较活泼的金属的氧化物加速效果好较活泼的金属单质加速效果好高价的金属氧化物加速效果好氧化物比单质加速效果好
实验组氧化铁和铁丝铜丝和铁丝氧化亚铁和氧化铁氧化铜和铜丝
(3)他们在对比实验过程中的如下操作,你认为不正确的是______

A.在同组实验时,都使用量筒量取相同量的过氧化氢溶液

B.在同组实验时,都使用托盘天平称取相同量的固体样品

C.在同组实验时,控制同组实验的浓度、用量等条件一致

D.在同组实验时,其中一个实验使用酒精灯加热

(4)下面是他们设计的四组实验装置.在两两对比实验中,下列观察(或测定)方法最难以比较样品对过氧化氢分解加速效果的是______

A.第一组是同时实验,观察比较反应过程中两个气球体积的变化情况

B.第二组是同时实验,观察比较反应过程中两者产生气泡的快慢

C.第三组是分两次实验,看木条是否能复燃

D.第四组是分两次实验,比较反应过程中收集一定体积氧气所需的时间

(5)他们的研究报告中有下列说法,你认为正确的是______

A.氧化铜是由氢氧化铜和稀硫酸反应制得

B.氧化铁是由铁在氧气中燃烧制得

C.通过多次对比实验都发现氧化铜的加速效果好于铜丝,因而得出初步结论:氧化铜对过氧化氧分解的加速作用好于铜丝

D.从氧化铁的加速效果好于铁丝,就可认定氧化物的加速作用好于单质.

信息填空

     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.  

         1    You probably think you will never be a top student. This is not necessarily so, however.

Anyone can become a better student if he or she wants to. Here's how:

Plan your time carefully. When planning your work, you should make a list of things that you have to do.

After making this list, you should make a schedule of your time. First your time for eating, sleeping,

dressing, etc. Then decide a good, regular time for studying.     2   A weekly schedule may not solve all

your problems, but it will force you to realize what is happening to your time.

Find a good place to study. Look around the house for a good study area. Keep this space, which may

be a desk or simply a corner of your room, free of everything but study materials. No games, radios, or

television. When you sit down to study, concentrate on the subject.

Make good use of your time in class.     3    Listening carefully in class means less work later. Taking

notes will help you remember what the teacher says.

Study regularly. When you get home from school, go over your notes, review the important points that

your teacher is going to discuss the next day, read that material.    4  If you do these things regularly, the

material will become more meaningful, and you'll remember it longer.

Develop a good attitude towards tests. The purpose of a test is to show what you have learned about a

subject. They help you remember your new knowledge. The world won't end if you don't pass a test, so

don't be over worried. 

        5  You will probably discover them after you have tried these.

A. There are other methods that might help you with your studying.

B. Don't forget to set aside enough time for entertainment.

C. Take advantage of class time to listen to everything the teacher says.

D. No one can become a top student unless he or she works hard.

E. Maybe you are an average student.

F. Make full use of class time to take notes of what the teacher says in class.

G. This will help you understand the next class.
