下面的句子成分实在搞不懂
this continental slope usually starts at a place somewhere near the 100-fathom mark and in the course of a few hundred miles reaches the true ocean floor at 2500-3500 fathoms.
下面的句子成分实在搞不懂this continental slope usually starts at a place somewhere near the 100-fathom mark and in the course of a few hundred miles reaches the true ocean floor at 2500-3500 fathoms.
start后面要加at,这里start是一个不及物动词.
a place是先行词,后面somewhere(关系代词)引出定语”near the 100-fathom mark“.
"(in the course of a few hundred miles) reaches the true ocean floor at 2500-3500 fathoms"是与"starts.mark"的并列成分,用and连接.(in the course of a few.)是状语
in the course of:In the process or progress of,在…期间,
this continental slope 为主语,谓语动词是starts at ,宾语为the 100-fathom mark ,地点状语in the course of a few hundred miles reaches the true ocean floor at 2500-3500 fathoms.at a place 和somewhere 都表示地点为什么用两次,and后面明明接...

this continental slope 为主语,谓语动词是starts at ,宾语为the 100-fathom mark ,地点状语in the course of a few hundred miles reaches the true ocean floor at 2500-3500 fathoms.
收起
这是一个并列句,用and连接。 共用主语是this continental slope; 谓语有两个,前半句的谓语是starts,即:this continental slope usually starts at a place somewhere near the 100-fathom mark. 其中at a place somewhere near the 100-fathom mark整体为地点状语,而near the 100-fathom mark是介词短语作为后置定语修饰a place,somewhere是修饰near的副词。所以,这前半句的意思是:这一大陆坡通常由水下大致100英寻线的某处起始。 后半句的谓语是reaches,即:this continental slope in the course of a few hundred miles reaches the true ocean floor at 2500-3500 fathoms. 其中in the course of a few hundred miles 是这半句的状语前置,in the course of 的意思是“在…期间,在…过程中”;宾语是the true ocean floor;地点状语是at 2500-3500 fathoms。这后半句的意思是:(这一大陆坡)逐渐向海底延伸了几百英里,最后在水深2500-3500英寻处才到达真正的海床。
