王磊同学在Science杂志上看到了一篇有关怎样的建筑物更抗震的文章,但缺少了5个小标题插图,现请你帮助王磊根据描述从A-F中选择5个小标题插图填入1 - 5相应的空格中。
There is a saying that, "Earthquakes don't kill people,but buildings do." It seems sadly true.Tens of thousands of people died under bricks(砖) of the destroyed buildings in Turkiye and Syria during the recent earthquakes.Is there a way to build earthquake-proof(抗震) buildings?Engineers have some life-saving ideas.
(1)BB
To prevent earthquake waves from going through the building,one way is to"lift" the building's foundation (地基) above the ground.The building can be built on top of pads(热状物),which are usually made up of steel and rubber.During earthquakes,only the pads move and the building stays steady.
(2)AA
Earthquake proof materials must be easy to bend(弯曲) without breaking.Some of these materials include steel,wood,memory alloy(合金) and bamboo.In Japan,most traditional houses are built with wood instead of concrete(混凝土).During earthquakes,wooden buildings bend to avoid building up stress.
(3)CC
Triangles(三角形) are very strong shapes.When a force comes to one of the corners of a triangle,it will be reduced by going down each side.When the two sides of the triangle are squeezed(挤[E),they lean(倾斜) on each other.During earthquakes,triangles can hold the building together when it sways(探见).Many earthquake Proof buildings use this shape in their design,both inside and outside the structure.
(4)FF
US company Arx Pax is developing magnetic field(磁场) technology that can raise houses above ground when earthquakes happen.When the sensors in the home feel earthquakes,they will tell"hover engines(悬停引擎)".These will create an opposing magnetic field to lift the house off the ground.Maglev trains use similar technology,so the company believes it can be used in buildings as well.
(5)EE
Japanese company Japan Dome House has made dome shaped(四顶状的) houses with Styrofoam(泡沫塑料).Styrofoam is a very light material.The whole house weighs only 80 kilograms.So when earthquakes happen,the house will not hurt people.

2.Dear Laura,
Thanks for your message.Yes,I'm having a great time on my student exchange program in France.I was a bit nervous before I arrived here,but there was no reason to be.My host family is really nice.They go out of their way to make me feel at home.The grandmother knows that I miss Chinese food a lot.So she actually learned how to make Chinese food!She also has a teenage granddaughter about my age who is really kind.She always talks to me in French to help me practice.You wouldn't believe how quickly my French has improved because of that.I'm very comfortable speaking French now.Although I still make lots of mistakes,it doesn't worry me as it used to.
My biggest challenge is learning how to behave at the dinner table.As you can imagine,things are very different from the way they are at home.For example,you're not supposed to put your bread on your plate.You're supposed to put it on the table!I thought that was pretty strange at first,but now I'm used to it.Another example is that you're not supposed to eat anything with your hands except bread,not even fruit.You have to cut it up and eat it with a fork.Another thing is that it is impolite to say you're full.If you don't want any more food,you should just say, "That was delicious." Also,you're not supposed to put your elbows on the table.I have to say that I find it difficult to remember everything,but I'm gradually getting used to it.I don't find French customs so strange anymore.
I'll write again soon and tell you more about my life in France.Hope you're having a good school year.
Yours,
Lin Yue
