Question 3. B parasites reproduce in the human liver(文中提及的是parasite經過liver再入血先繁殖)and grow stronger there. (沒有提及）

Question 4. A. Ecosystem 全文都沒有特別提及。同種蚊的競爭不算是ecosystem(生態系統）生態系統需要包括描述兩種或以上的生物的生存關係。

可是他文章中第五行的意思不是說先經肺臟後繁殖長大嗎～

Marceline

Line 5-6 : the parasite 寄生蟲travels first（首先） to liver （去肝）and then（然後） to the **bloodstream**,(進入血管內）where it （在那裡，it是指血管內）reproduces（繁殖） and destroys（破壞） red blood cells. （紅血球細胞）

Marceline

文中沒有提及它長大/變得強壯，只是說寄生蟲的數量大量增加。

Marceline

而且B的答案是說它們在肝內繁殖，這個已經錯了。
