難句突破：

(1)   This is good news for the mine's 1,000 or so employees and for the town, which has depended on the diamond business since Sir Thomas Cullinan discovered a prospect there in 1898 that contained kimberlite, a rock that can be rich in diamonds.

[主體句式] This is good news for ...

[結(jié)構(gòu)分析] 這是一個簡單句，for后面的賓語比較復(fù)雜，which 引導(dǎo)的非限定性定語從句修飾the town，在該從句中有一個since引導(dǎo)的狀語從句；在該狀語從句中，that 引導(dǎo)的定語從句修飾prospect, a rock...是kimberlite的同位語。

[句子譯文] 這對于這個礦的1000名左右的雇工以及這個小鎮(zhèn)來說是個好消息，這個小鎮(zhèn)從1898年Thomas Cullinan爵士發(fā)現(xiàn)該礦含有金伯利巖（可能富含鉆石的一種巖石）后，就一直依賴鉆石生意存活。

(2) It started focusing on higher returns rather than market share, and has been revamping its mine portfolio, selling off mines that are no longer profitable and investing in more enticing operations, such as its mine off the west coast of South Africa, its Voorspoed operation in the Free State province, and two new mines in Canada.

[主體句式]It started focusing on..., and has been...

[結(jié)構(gòu)分析] 這是一個并列句，由連詞and 連接，后半分句結(jié)構(gòu)比較復(fù)雜；has been 后面帶有三個并列的成分，第二個成分selling off mines后面有that 引導(dǎo)的定語從句，第三個成分中such as 后面都是用來修飾operations的。

[句子譯文] 它開始修關(guān)心更高的回報率而不是市場份額了，也一直在修改它的礦產(chǎn)組合，賣掉不再盈利的礦產(chǎn)，投資更讓人動心的項(xiàng)目，如南非西海岸的礦產(chǎn)、自由州省的Voorspoed項(xiàng)目、加拿大的兩處新礦。
