1. Lying under waters acrss the glbe are an estimated three millin shipwrecks.
Paraphrase: It is believed that arund three millin shipwrecks are lying under waters acrss the glbe.
本句为倒装结构，句中的 Lying under waters acrss the glbe 放在句首表示强调。课文中还有类似的句子。例如：
Para 1 1) Amng these is the Esmeralda, the earliest wreck frm the age f the Eurpean explratin f Asia.
Para 3 2) Swimming thrugh these black depths is the barreleye, a strange fish with eyes that can lk upwards thrugh its transparent frehead.

Given her interest in children, teaching seems the right jb fr her. 考虑到她喜欢孩子，教书看来是很适合她的工作。
It is difficult fr such a little child t finish the task alne.
it 为形式主语，真正的主语为 that explratin f the ceans cntinues t lead t discveries in varius scientific fields。为了避免句子头重脚轻，故用 it 作形式主语，这种用法在英语中很常见。例如：
It is nt clear whether he will cme r nt.
3. In these waters, mre than 200 metres deep, where light cannt reach, are extrardinary creatures that appear as if they are straight ut f science fictin.
Paraphrase: Extrardinary creatures that lk as thugh they are smething directly ut f science fictin live in these waters with a depth f mre than 200 metres, which are s deep that light cannt reach them.
本句为一个复合句，其中包含了两个定语从句，分别是：非限制性定语从句 where light cannt reach，修饰先行词 waters；限制性定语从句 that appear as if they are straight ut f science fictin，修饰先行词 creatures。
4. The Jialng even hlds the recrd fr the deepest dive by a manned submarine, at 7,062 metres, giving China its place alngside the wrld’s tp cean explrers.
Paraphrase: The Jialng is the manned submarine t have dived t a recrd depth f 7,062 metres. Because f this, China is cnsidered ne f the best cean explrers in the wrld.
本句中 hld the recrd 表示 “保持纪录”。
句中 alngside 是介词，表示“与……同等重要”。例如： When he dies he will take his place alngside Dickens as ne f the truly great writers f his time.他死后会成为他那个时代真正的伟大作家之一，与狄更斯齐名。
5. Being a tugh envirnment f cmplete darkness, enrmus pressure and intense cld, the cean depths have lng been beynd the reach f human explratin.

The sht was well beynd the reach f the galkeeper.这次射门使守门员鞭长莫及。
本句中 Being a tugh envirnment f … 作为现在分词短语置于句首，表示 the cean depths 的状态。
本句中的 beynd the reach f … 表示“超过……能力之外；无法达到”。例如：
Imprtant expressins and sentences:

Sme parts f Shakespeare’s life will always remain unknwn. 莎士比亚一生中的某些部分永远不会为人所知。
