河北省石家庄市第四十八中学2024年中考二模英语试题
Boys and girls, let's do an experiment in today's lesson.
Things you need to prepare:
Instructions:
1) Fill the glass or jug about 2/3 full with water.
2) Drop the egg carefully into the glass and watch it going down towards the bottom.
3) Take the egg out and add about 5 spoons of salt. Test to see if your egg goes up.
4) Add more salt if the egg is still at the bottom.
The science behind it:
Things go down in the water when they are denser (密度更大的) than the water. By adding salt we make the water denser. Once the water is denser than the egg, it goes up.
You can also try other things to see if you can have the same result.
Example in daily life:
The Dead Sea is the lowest sea in the world. The Dead Sea has a high concentration (浓度) of salt. So there is nothing living in the Dead Sea. As the experiment above, people can also float (漂) in it. But it is not good to float for a long time.
①Water. ②Oil. ③Eggs. ④Salt. ⑤Glass.
A①③④⑤ B. ①②④⑤ C. ②③④⑤ D. ①②③④
With the development of our society(社会), many families become rich. This development brings us many benefits. For example, we do not have to worry about basic life like food, water and clothing any longer. {#blank#}1{#/blank#} While life becomes more comfortable, many children become" giant babies(巨婴) ", depending on their parents for everything.
Yesterday, I read a report that said many students in a middle school in Hongzhou didn't know how to tie their shoes. {#blank#}2{#/blank#} Tying shoes is a basic life skill. Why couldn't these teenagers do such a simple thing?
I think there are two main reasons. First, parents must shoulder the blame(指责). In my opinion, parents should leave their children to do some basic things— such as tying shoes, washing clothes and heating meals. How can children learn these basic life skills if their parents do everything for them? Second, school are to blame. These days, school are paying too much attention to students' marks.{#blank#}3{#/blank#}
But, above all, children themselves must realize that it is terrible to become" giant babies".{#blank#}4{#/blank#}
It is time for us to take action to stop more children from becoming " giant babies".
A. I felt surprised. B. What on earth should teach students? C. However, just as the old saying goes," Every coin has two sides." D. If they don't want to learn basic life skills, who else can help them? E Many of them ignore(忽视) the importance of students' all- round development. |
