考的不好 有一點東西分享給大家
長聽力:
geology - 鑽石
有兩張圖，第一張是地球切面 有core, mantle crust
第二張和鑽石有關 Kimberlite pipes, indicator minerals
聽到這題的時候很興奮，因為之前AT有作過類似的閱讀測驗
把相關的文章貼在下面給大家參考，其實只要把握上面提到的關鍵字就ok了，題目沒有很難‧
我記得有考鑽石生成的要素，我選pressure and heat
還有為什麼要找indicator minerals，我選因為和鑽石的存在有很高的關連
Diamonds are almost impos-sible to detect directly because they are so rare: very rich kimberlite
Line pipes, the routes through which diamonds rise, may contain only three carats of diamonds per ton
of kimberlite. Kimberlite begins as magma in Earth’s mantle (the layer between the crust and the core).
As the magma smashes through layers of rock, it rips out debris, creating a mix of liquid and solid material.
Some of the solid material it brings up may come from a so-called diamond-stability field, where
condi-tions of pressure and temperature are conducive to the formation of diamonds. If diamonds are to
sur-vive, though, they must shoot toward Earth’s surface quickly. Otherwise, they revert to graphite or burn.
Explorers seeking diamonds look for specks of “indicator minerals”peculiar to the mantle but carried up
in greater quantities than diamonds and eroded out of kimberlite pipes into the surrounding land. The stan-dard
ones are garnets, chromites, and ilmenites. One can spend years searching for indicators and tracing them back to
the pipes that are their source; however, 90 percent of kimberlite pipes found this way are barren of diamonds,
and the rest are usually too sparse to mine.

1. Lincoln Highway:
這條路橫跨美國，目的是將小鎮和大都市連結‧雖然路線和一些道路重複，但是有帶動沿路的經濟，有許多店家都以Lincoln為名，例如Lincoln Cafe...
店家會在路旁設招牌吸引motorists停下來消費，這裡有一題單字beckon=invite
另外，有一段講為什麼取名Lincoln，因為Lincoln當初也是把美國南北結合‧(有題) 最後一段說某年有一個法案通過導致Lincoln Highway被拆成好幾段而且改成列入其他公路，所以Lincoln Highway好像就消失了(有題)
2. 一種土(clay)吧:
說用這種土蓋房子會造成一些問題，但有時候是人為的，例如 less maintenance(有題)‧然後提到解決的辦法是consolidate with 某東西或者
cut away接著舉了一些都市裡建築物的例子‧其他記不得啦
作文:agree or disagree - teachers should be paid according to how much their students learn
希望作文拿高分一點啊(好像只有滿分才有救了)，我不想再考一次
以上給大家參考，希望有點幫助
我要回去接受AT的荼毒了
