2019屆高考英語第一輪單元基礎知識復習2
6.d主旨大意題。由第一段的開門見山，點明話題到最后一段的重申主題，對未來這種新系統展望，可得出最準確的題目是d，a錯在protecting students b項錯在by wireless industry, c 項錯在national disasters。
b篇：1.b 細節理解題。由第一段關鍵句““i’m going to college, but i need a way to pay for it,”.” 可知其目的是為了支付大學的費用。
2. a判斷正誤題。由第二段關鍵句“buck wrote a check for $1000”和“buck kicked in another $1000.”，可知是投資人，他投入了很多運轉資金。b項錯在a professor of …c項錯在studying at ….d項錯在rented a …
3.c推理判斷題。由第三段的內容描述，but business didn’t go smoothly as they expected. deluca says, “after six months, we were doing poorly, but we didn’t know how badly, because we didn’t have any financial controls.” all he and buck knew was that their sales were lower than their costs.可判斷出他們的第一家商店由于經營不善，以虧本失敗而告終。
4.d細節理解題。由第四段的“we convinced ourselves to open a second store. we figured we could tell the public, ‘we are so successful, we are opening a second store.’可知他們之所以在開第二家商店主要就是為了向別人證明他們是能夠成功的。
5.a推理判斷題。總結全文故事發展脈絡，根據第四段最后一句話“still, it was a lot of learning by trial and error.可推論出他們取得成功的主要原因在于他們的堅持不懈，反復嘗試。
