首先沒換，雖然可能快要換了，還是來分享一下，希望下次可以有佳績
數學： 1.一個直角三角形斜邊(c)5，以三角形的各三個邊(a,b,c)成三個填色半圓問如何可知道三個半圓的加總面積
(1) a^2+B^2+C^2 = 150
(2)c=5
選兩者都可
2. 一個圓柱形的can可以放入最長25的某物，然後罐子深20 求罐子體積
一開始想說20怎麼可以放25的，後來想起來可以斜放得到圓柱底為15
就可以解了
3. 一台機器做了兩小時完成了task的4/1 隨後另外一台機器啟動 兩台"又" 一起做了4.5小時 問第二台機器獨自運轉需要多久完成?
(注意!因為是又 所以第一台總共運轉了6.5小時)
4.一個表格列出來了在任意時間到ABCD四個不同路口所產生燈號的機率，問只有在BC兩個路口遇到燈號亮起的機率。
5.x先增加了r% 隨後又增加了y問這兩次增加總共是多少(用x,r,y來表示)
6.有人買了n+5隻的筆,之後分給6個同事(每個人一樣數量)剩下的自己留著，問他留下多少支給自己
(1)(2)都不記得了
V：
1. CR 跟GWD某題完全一樣 直接貼：
Plankton generally thrive in areas of the ocean with sufficient concentrations of certain nitrogen compounds near the surface, where plankton live. Nevertheless, some areas, though rich in these nitrogen compounds, have few plankton. These areas have particularly low concentrations of iron, and oceanographers hypothesize that this shortage of iron prevents plankton from thriving. However, an experimental release of iron compounds into one such area failed to produce a thriving plankton population, even though local iron concentrations increased immediately.
Which of the following, if true, argues most strongly against concluding, on the basis of the information above, that the oceanographers' hypothesis is false?(負負得正
- ANot all of the nitrogen compounds that are sometimes found in relatively high concentrations in the oceans are nutrients for plankton.
- BCertain areas of the ocean support an abundance of plankton despite having particularly low concentrations of iron.
- CThe release of the iron compounds did not increase the supply of nitrogen compounds in the area.
- DA few days after the iron compounds were released, ocean currents displaced the iron-rich water from the surface.
- EThe iron compounds released into the area occur naturally in areas of the ocean where plankton thrive.
- 2.也是CR 講一個urban legend要能在社會上流傳，必須要讓社會有一些甚麼甚麼(應該是要讓社會能感同身受甚麼的)，然後是利用聽到或是讀到的人的情緒的波動還有他們對於這個legend的信任(相信這個故事是對於某些危險的啟示) 問以上可以得到哪個選項中的結論
- 3.CR 問輪胎灌氣：有些輪胎灌N 有些是灌一般空氣，然後講了些灌N的好處，但是N比較貴又不好找,所以結論推斷要一般大眾使用N是不太可能的。好像是問support
- 其他的不太記得了，有想到再補
