今天我們要學的詞是 inroad.

inroad 的意思是進軍、進展，成功進入。 Researchers are beginning to make inroads in diagnosing pancreatic cancer - one of the deadliest kinds of cancer as its symptoms only show up when the cancer is advanced. 研究人員開始在胰腺癌診斷上取得進展，由于胰腺癌的癥狀只有在病患晚期才會出現，因此是最致命的一種癌癥。

Target's store in Times Square has created an inroad for the department store chain in dense, urban markets, which largely remain a frontier for fellow mass merchant Walmart. 塔吉特的紐約時代廣場分店為這一百貨連鎖店打入人口稠密的都市開辟了道路，同是大規模零售商的沃爾瑪在很大程度上還沒有開發這一市場。
