7月17 北美考的放幾隻小狗

vivax

作文：
有一個analyst寫了一個意見去 A city council 發表了對A city中那個正在實行的two－way strategy發表意見：
two way strategy目標是減少交通traffic 增加ridership,增加了affording housing和鐵路建設.
Analyst批評說在在過去的5年中,the project has spent over 30millions on the 82nd street Station, but it has only 15% increase on the ridership 還是坐地鐵的人，the project on the 108th street has spent only 5 millions, but it has 30% increase on the ridership  還是坐地鐵的人. Therefore, the analyst suggests that the remaining budgeted on the 82nd street station should redirect to 108th.

IR:
花了10分鍾做得到4分！本想留力在數學因為背了JJ可是換庫！人品不好希望這次放狗有助提升人品








數學：
數學嚴重跪了！我不放了我記得都是你們不用JJ都能輕易回答的問題
算了 放一個吧
DS
is p a prime number?
A. 15<p<20
B. p-2 is a prime number

好多DS都不會做...怎麼辦啊：（

第一篇 好簡單

the value of natural resource.

普通的東西你在市場上可以買的我們都可以知道他的價格，可是天然資源的價格我們應該怎麼平估呢？然後提出要估價天然資源的限制 ！（好短 3／4頁）
q1：以下那些例子可以xxx???
a. will you pay to access natural park/beach?
b. how much would you pay for the natural resource?

第二篇.....

關於未開方的地方還是什麼,大概是講有的地方沒有給車access／未開發的地方物種有很少可是有很多exotic species?????????
開發的地方剛好相反,有大量普通的種類但沒有珍貴的物種

第三篇

開頭是 Canadan Geographist Martin Gibling.....................等考古

SC:全忘了

CR:
1. 在英國有研究發現人很容易在右邊生太陽cancer，因為英國是右'車太'開車所以右邊會常哂到大陽, 問如何證明這原因是有限的？
選擇有：
a.經常坐副架駛的人有沒有這情況？
b. 英國人都開車還是什麼的..?

2. 把乾手用的紙換成用電的乾手機,乾手機比較省錢,  問怎麼樣才能決定換？
a. 長期保養乾手機的錢不會變化很大這10年內.
b. 現在把紙換成乾手機的成本不會大於你以後能省下來的錢

请问是这篇吗?
For decades, the Canadian geologist Martin Gibling has been intrigued by the tough-to-prove hypothesis that land plants created the shape of modern rivers hundreds of millions of years ago.

Plant roots reinforced the ground, the thinking goes, creating stable banks that funneled what once were wide, shallow water flows into narrower and deeper channels. By extension, that set the stage for lots of significant Earth history events, including the rise of human civilizations in modern river basins so many millennia later.

Now Gibling and postdoctoral scientist Neil Davies, both at Dalhousie University
, have strengthened this case. When the pair compared a much-improved plant fossil record with evidence of how rivers changed very long ago, the transitions matched up.
Back in the Cambrian period, which ended some 500 million years ago, the geologic record indicates that rivers were very shallow but wide things, almost floods that allowed rainwater to wash from largely barren solid ground to sea. Deposits left behind were preserved as sheets of coarse grains, some of which suggest these rivers were 1,000 or more times as wide as they were deep.
