课件31张PPT。Unit 3Section ⅠStep 1Step 2Step 3Step 4Step 5There are a great many plants and animals that live under the sea. Do you know something about sea turtles? And how they live under the sea? Please read the following passage to get the answer. Sea turtles are sometimes referred to as “marine turtles”， referencing the fact that they have adapted to living primarily in the marine environment. All seven living species of sea turtles are endangered, and conservation efforts all over the world are attempting to prevent the extinction of sea turtles. The loss of sea turtles would not just be a blow to biodiversity: sea turtles are also important for the health of the world's oceans. Like other turtles, sea turtles have a hard shell into which they can retreat. Their front legs have adapted into a flipper-like (鳍状的) form which allows them to swim rapidly and efficiently, and their bodies are slightly flattened to reduce resistance in the water. Some sea turtles can also use their flippers for climbing. The sea turtle has developed a respiratory (呼吸的) system which allows it to dive and stay underwater for as long as five minutes. Depending on the turtle's level of activity and stress, it may need to surface soon for air. Sea turtles breathe in explosively, filling their lungs with enough air to supply them during dives. Sea turtles feed on other marine life and seagrass, a flowering plant which is widespread in the world's oceans. They can be found in every ocean except the Arctic. Sea turtles are especially vulnerable (易受伤的) during egg laying, since many are slow and unhandy on land, and the eggs may be broken by careless walkers or viewed as a tasty snack by numerous predators. Once the eggs hatch, the young make their way to the ocean and begin their water life. The smallest sea turtles reach a length of around 30 inches, while the largest can exceed six feet. Sea turtles live for up to 80 years, and once they reach their maturity, they are difficult for predators to kill, thanks to their hard shells. They are easily vulnerable, however, to trawling and a variety of other human activities, along with changes in the marine environment such as coral bleaching (珊瑚白化) and nutrient pollution.1．Match the pictures and the proper introductions.(1)____ ____ a mammal which lives in the sea and looks

他受不了人家那样开他的玩笑。
Having been invited, Mr Li went there to give a speech though he was busy.
李先生受邀去那儿作演讲，尽管很忙，但他还是去了。二、动词-ing形式被动式的语法功能

在公共场合被嘲笑是非常可怕的经历。
2．作宾语
I don't like being laughed at in public.
我不喜欢当众被人嘲笑。[考题印证1](2012·福建高考)China recently tightened its waters controls near the Huangyan Island to prevent Chinese fishing boats from ________ in the South China Sea.
A．attacking B．having attacked
C．being attacked D．having been attacked解析：选 考查非谓语动词。句意：最近中国加强对黄岩岛附近水域的控制以防止中国渔船受到攻击。prevent ...from ...“阻/防止……做某事”。因渔船是被攻击，故用动名词的被动语态。动名词的一般时态表示动名词的动作与谓语动词同时发生；动名词的完成时表示动名词的动作发生在谓语动词之前，故C项正确。C3．作宾补
I heard this song being sung in English then.
那时，我听过有人在用英语唱这首歌。
4．作定语
The meeting being held now is very important.
现在正在召开的会议非常重要。[点津] 动词-ing形式的一般被动式表示一个被动的动作正在进行；过去分词表示一个被动的动作已经完成；不定式的被动式表示将来的一个被动的动作。

A．Having been asked B．To ask
C．Having asked D．To be asked
解析：选 考查非谓语动词。分析题干并根据“I missed a wonderful film”可知，此处应用现在分词作原因状语；ask和I是动宾关系，故用被动语态；ask这一动作发生在missed这一动作之前，故应用分词的完成式。答案为A项。A6．作表语
The South China is being flooded because of the continuous heavy rain.
由于持续的强降雨，华南正被洪水围困。三、在动词-ing形式的被动式前加否定副词not便可构成其
否定形式

没有被邀请参加聚会，他感到很不高兴。
Not having made preparations, they failed.
因为没有准备，他们失败了。四、使用注意事项

形式表示被动含义。

投诉信是人们在现代生活中应用最为广泛的书信形式。现代生活中当人们对商品或服务不满时，我们有权投诉。写投诉信时要客气，但语气要坚定；另外要证明责任确实在商家；最后要明确问题出在哪儿及你的具体要求，还可加上由此给你带来的不便或伤害，以加强投诉信的说服力。
写作时注意以下几点： 1．开头：写投诉信时，要自我介绍，开门见山地提出写信的原因，然后陈述事情，交代投诉内容，表明写信的目的和要求。
2．正文：说明情况原委，表达自己的不满，讲清利害，分析利弊。告诉对方你因此受到的伤害或不便，最后提出自己的合理要求和解决问题的建议，表明希望如何处理。
3．结尾：表达希望迅速恰当地解决问题的强烈愿望，希望尽快得到满意的答复。
注意：写投诉信要明确人称和时态。人称以第一人称为主，时态以一般过去时为主。[黄金表达]1．It is a great pity that we found there's something wrong
