So sorry I can't type Chinese here so only can communicate via English.
Pure Physics was quite tou ...
It is okay, as long as you are comfortable typing english and i don't have problem of understanding.
ok, i can still remember those question a bit. the typhoon wave, you basically calculate and you check from the given data, which level the wave belong to, base on your result, then you pick the answer accordingly.
Light bulb question the potential divider, you must recall how to draw. I spend much time working out the last 2 question (2 marks each), you just had to know clearly the relationship of power, energy dissipated and know exactly the arrangement.
The optic question, hehe, according to my teacher, he said a lot of students around the country will get this question wrong, including the students from good schools. To solve this question, the most efficient way is try to draw the object on the graph, which the question says what if it move closer to the lens( is it?), then you work out the new position of the image. And you would know the answer by referring to this.
Swimmer? I wrote "The swimmer push the water behind", but i think I should write " the swimmer push the wall using her leg", to be more exact. Then the effect of her work will be " the swimmer herself is being push forward as a result". i think this question is about describing, the hard part is the first part, the energy change. I heard my teacher said that it even involves chemically change, WTF !!!
Bell curve, ok, got it. but i dont know my bell curve. =_=
dont worry about the 综合填空, just a small part.
El papers, I really don't want to evaluate my performance about it, I have left so many flaws and disappointments ah~ it was just beyond my control~ |
