你喜欢大海吗？阳光照耀下她妩媚多姿；狂风暴雨下她凶猛狂暴，除此以外你还了解大海的什么呢？ When you look at the map of the world you will find there is more sea than land． The sea covers three quarters of the world． The sea is also very deep in some places． It is not deep everywhere． Some parts of the sea are very shallow(浅的)．But in some places the depth of the sea is very great． There is one spot，near Japan，where the sea is nearly 11 kilometers deep！The highest mountain in the world is about 9 kilometers high． If that mountain were put into the sea at that place，there would be 2 kilometers of water above it! What a deep place! If you have swum in the sea，you know that it is salty．You can taste the salt． Rivers，which flow(流动) into the sea, carry salt from the land into the sea． Some parts of the sea are saltier than other parts． There is one sea，called the Dead Sea，which is very salty． It is so salty that swimmers cannot sink！Fish cannot live in the Dead Sea! In most parts of the sea，there are plenty of fishes and plants． Some live near the top of the sea, others live deep down． There are also millions of tiny living things that float(漂浮) in the sea． These floating things are so small that it is hard to see them． Many fish live by eating these． The sea can be very cold． Divers who go deep down in the sea know this． On the top the water may be warm． When the diver goes downwards，the sea becomes colder and colder． Section Ⅰ Warm-up & Lesson 1—Comprehending 1．sign n． 手势；符号 2．underwater adj． 在水下，供水下用的 3．voyage n． 航海；航空 4．persuade vt． 说服，劝服 5．present-day adj． 当今的，现代的 6．deed n． 行为，行动 7．participate vi．参加→participation n．参加 8．evaluate vt．评估，评价→evaluation n．评估 9．arrange vt．安排，准备→arrangement n．安排 10．hunt v．打猎，猎杀→hunter n．猎人 11．frightening adj．令人惊恐的，骇人的→frighten vt．使惊恐→frightened adj．惊恐的 12．explorer n．探险家→explore vt．探险 13．unknown adj．不知道的，未知的→known adj．已知的，闻名的 14．eventually adv．最终，终于→eventual adj．最后的 15．apologise vi．道歉→apology n．道歉 1．fill__out 填写 2．set__sail 启航 3．according__to 根据，依照 4．get__into__trouble 陷入麻烦，陷入困境 5．make__it__to 到达 6．in__search__of 寻找，寻求 7．far__from 远离 8．prepare__for．．． 为……作准备 1．The first．．．to do．．． The Vikings were the first Europeans to__reach__America(到达美洲的)． 2．where引导的定语从句 By around 900 AD，there were many places in Northern Europe where__the__Vikings__chose__to__live (有北欧海盗选择居住在那里)． 3．现在分词作后置定语 ．．．there were as many as 10，000 Vikings__living__in__Iceland(生活在冰岛上)． 4．find＋n．/pron．＋介词短语 Biarni was hoping to join his father who was with Eric，but he was blown off course and__found__himself__in__an__unknown__land(发现自己在一个未知的地方)，from where he eventually reached Greenland． 5．what引导的名词性从句 Leif followed Biar ... ...
