由1565可知，不能確定的是番茄被引入中國的“時間”，故用when引導主語從句，在從句中作時間狀語。第二十八頁，共36頁。2.Grandmapointedtothehospitalandsaid,“That’swhenIwasborn.”when→where

醫院應是她出生的“地點”，故用where引導表語從句，在從句中作地點狀語。第二十九頁，共36頁。3.“Everytimeyoueatasweet,drinkgreentea.”Thisisthatmymotherusedtotellme.that→what

意思是“這就是我兄弟以前常常跟我說的”，在表語從句中作tell的賓語，故用連接代詞what。4.Itmakesthebooksoextraordinaryisthecreativeimaginationofthewriter.It→What

引導主語從句并在從句中作主語，用連接代詞what。第三十頁，共36頁。5.Fromspace,theearthlooksblue.Thisishowaboutseventy-onepercentofitssurfaceiscoveredbywater.how→because

句中it作形式主語，that引導主語從句。7.Asmanyasfivecoursesareprovided,andyouarefreetochoosewhateversuitsyoubest.whatever→whichever

指在前面提到的五種課程中“任選一種”,有選擇范圍，要用whichever引導賓語從句，并在從句中作主語。whichever與whatever的區別，類似于which與what，有范圍用which，無范圍才用what。第三十二頁，共36頁。8.Itdoesn’tmatterifyoupaybycashorcreditcardinthisstore.if→whether
