Sea exploration has caused many problems and will continue to cause more. 返回导航 下页 上页 人教英语 选择性必修 第四册 More exploration means more pollution. The Deepwater Horizon spilled② over 200 million gallons of oil into the sea in 2010.

Climate change is warning us that something is very wrong. 句中mining for resources是动名词短语作主语。 句中which引导非限制性定语从句。 返回导航 下页 上页 人教英语 选择性必修 第四册 Overfishing⑥ is another problem.

If we do not protect it，future generations will not forgive us. 返回导航 下页 上页 人教英语 选择性必修 第四册 Text 2 To truly understand our planet，we must explore the oceans which cover most of it. Opponents⑨may be concerned，but sea exploration is important for our future. For example，scientific research ships can help address⑩ important issues such as climate change. We need to understand what is happening to our planet so that we can take action⑪. Therefore，more research is necessary. 返回导航 下页 上页 人教英语 选择性必修 第四册 句中to truly understand our planet是不定式短语作目的状语。 句中so that引导目的状语从句。 返回导航 下页 上页 人教英语 选择性必修 第四
