例1：本合同自买方和建造方签署之日生效。This Contract shall come into force from the date of execution hereof by the Buyerand the Builder.
例2：下述签署人同意在中国制造新产品，其品牌以此为合适。The undersigned hereby agrees that the new products whereto this trade name is more appropriate are made in China.
二、谨慎选用极易混淆的词语
abide by 与 comply with 都有“遵守”的意思．但是当主语是“人”时，英译“遵守”须用 abide by。当主语是非人称时，则用 comply with 英译“遵守”。
例 3：双方都应遵守/双方的一切活动都应遵守合同规定。
Both parties Shall abide by/All the activities of both parties shall comply with the contractual stipulations.
2.3 change A to B 与 change A into B
英译“把 A 改为 B”用“change A to B”，英译“把 A 折合成/兑换成 B”用“change A into B”，两者不可混淆。
例 4：交货期改为 8 月并将美元折合成人民币。
Both parties agree that change the time of shipment to August and change US dollar into Renminbi.
2.4 ex 与 per
源自拉丁语的介词 ex 与 per 有各自不同的含义。英译由某轮船“运来”的货物时用 ex，由某轮船“运走”的货物用 Per，而由某轮船“承运”用 by。
例 5：由“维多利亚”轮运走/运来/承运的最后一批货将于 10 月 1 日抵达伦敦。
The last batch per/ex/by S.S. "Victoria" will arrive at London on October (S.S. = Steamship)
2.5 in 与 after
当英译“多少天之后”的时间时，往往是指“多少天之后”的确切的一天，所以必须用介词 in，而不能用 after，因为介词 after 指的是“多少天之后”的不确切的任何一天。
例 6：该货于 11 月 10 日由“东风”轮运出，41 天后抵达鹿特丹港。
The good shall be shipped per M.V. "Dong Feng" on November 10 and are due to arrive at Rottedaml in 140 days. (M.V.= motor vessel)
2.6 on/upon 与 after
当英译“……到后，就……”时，用介词 on/upon，而不用 after，因为 after 表示“之后”的时间不明确。
例 7：发票货值须货到付给。
The invoice value is to be paid on/upon arrival of the goods.
例 8：卖方须在 6 月 15 日前将货交给买方。
The vendor shall deliver the goods to the vendee by June 15.(or: before June 16，说明含 6 月 15 日在内。如果不含 6 月 15 日,就译为 by June 14 或者 before June 15。)
例9：如果上述货物对船舶和（或）船上其它货物造成任何损害，托运人应负全责The shipper shall be liable for all damage caused by such goods to the ship and/or cargo on board.
3.1.2 by and between
常用by and between强调合同是由“双方”签订的，因此双方必须严格履行合同所赋于的责任。
例10：买卖双方同意按下述条款购买出售下列商品并签订本合同。This Contract is made by and between the Buyer and the Seller, whereby the Buyer agrees to buy and the Seller agrees to sell the under mentioned commodity subject to the terms and conditions stipulated below.
