22.的B選項是從哪裡看出來的勒
謝謝

Q22:
The passage is primarily concerned with discussing

A.the composition of Earth’s mantle
B.how the Hawaiian Islands were created
C.what causes Earth’s surface plates to move
D.two different mechanisms by which volcanoes are formed
E.why most volcanoes occur at plate boundaries
Answer: D

我認為B選項的Hawaii Isalnd只是用來舉例說明上一句文字
不算全文主旨

我想請問Q23的正確答案(B)從哪裡可以看出彼此年齡不一樣呢?

Q23:
It can be inferred from the passage that a chain of volcanoes created by a mantle plume would most likely be characterized by

A.a curved outline
B.constituent volcanoes that differ from each other in age
C.occurrence near a plate boundary where one plate bends under another
D.appearance near many other volcanic chains
E.rocks with a wide range of chemical composition

Answer: B

我可以請問 25題的
A.An untapped reservoir of hot rock in the base of the mantle
是怎麼個錯法嗎？
我第一次做。糊里糊塗選A選對了
今次做的仔細。卻選到了E
怎生辦法阿

試試看用徐天后的方法
according to the passage 細節題, 答案一定在文章中
a hot spot 第二段44line

看44line那一句, the surface mark of an established plume is a hot spot,就是在形成了的plume的地表記號=hot spot

(A) an untapped reservoir -- 未噴發即未形成，就不會產生hot spot -- 刪
(B) at the edge of plate -- 指第一種火山 -- 刪
(C) under tremendous pressure -- 指第一種火山 -- 刪
(D) unique to the Pacific plate -- 文章沒講, 且unique武斷字眼
(E) a plume (可接受，讀過的句子有）hot rock near core (line 33) -- hot rock collect in the base of the mantle

ans: E

Answer: B

1.這重點是constituent volcanoes-->火山構成的火山 that differ from each other in age--->用來補述 ... 前面大衛有講過

2.如果硬要說 age的話
Because the source of a hot
spot remains fixed while a surface
plate moves over it, over a long period
of time an active plume creates a chain
of volcanoes or volcanic islands, a
track marking the position of the plume
relative to the moving plate.

我想是看這一句吧
