2017雅思閱讀長(zhǎng)難句例句分析(3)
題目:
Therefore, like the timber barriers, the Fanwall barrier can be built without expensive concrete footings or piles, speeding the construction time up and reducing costs.
分析:
can be built是被動(dòng)語(yǔ)態(tài),like the timber barriers是介詞短語(yǔ)做狀語(yǔ),speeding the construction time up and reducing costs是分詞短語(yǔ)做狀語(yǔ)。
