ing形式和ed形式作宾语补足语
课堂要点精析
补足语是用来说明宾语或主语情况的成分，在英语中，ing形式和ed形式都可以作补足语。
1．ing形式作宾语补足语
ing形式作宾语补足语时，宾语与宾语补足语之间在逻辑上是主谓关系。能接ing形式作补语的有两类动词：
(1)感觉、感官类动词：see, notice, watch, look at, hear, listen to, find, feel, smell等。
◆He heard the wind blowing outside.
他听到外边在刮风。
◆I felt my heart beating faster.
我感到我的心跳得更快了。
(2)使役动词：keep, get, leave, have等。
◆I’m sorry to have kept you waiting for so long.
不好意思让你等这么久。
◆The captain got the soldiers moving toward the front after a short rest.
休息了片刻之后，上尉让士兵们朝前线行进。
2．ed形式作补语
ed形式作宾语补足语既可表示被动又可表示动作已经完成；宾语与宾语补足语之间在逻辑上是动宾关系。ed形式作补语的常见情况：
(1)位于feel, find, hear, notice, see, smell, observe等感官动词后作补语。
◆She was glad to see her child taken good care of.
她很高兴看到自己的孩子被照顾得很好。
◆I was sleeping when I heard my name called.
我正在睡觉，这时听到有人喊我的名字。
(2)位于get, have, make, keep, leave等使役动词后作补语。
◆They are going to have the house painted white.
他们准备把房子刷成白色。
2．with复合结构中作宾补的非谓语动词
“with＋宾语＋宾补”结构可在句中作定语或状语(表示原因、时间、条件、伴随、方式等)，宾补可以是名词/形容词/副词/介词短语/现在分词/过去分词/不定式。 在此我们重点讲解宾补是分词和不定式的情况。
(1)with＋名词/代词＋现在分词。现在分词可表示主动和动作正在进行。
◆He lay on the grass with his eyes looking at the sky.
他躺在草地上，眼望着天空。(伴随状语)
(2)with＋名词/代词＋过去分词。过去分词可表示被动和动作已完成。
◆With his hair cut, he looked much younger.
理了发，他看起来年轻多了。(原因状语)
(3)with＋名词/代词＋不定式。不定式表示动作尚未发生。切记：不定式一般情况下都用主动形式。
◆With a lot of homework to do, I can’t go skating with you.
因为有很多家庭作业要做，我不能和你一起去滑冰了。(原因状语)

《Earth first》SectionⅠPPT
第一部分内容：教材背景
科学家警告：北极海冰的加速融化会造成不可控制的全球气候变化。
Melting Arctic Sea Ice Could Start
Uncontrollable Global Climate Change
The rapid melting of the Arctic sea ice could be about to bring about catastrophic(灾难性的) events across the world, scientists have warned.
The effects of the melting ice could be felt as far away as the Indian Ocean as the warm weather sets off 19 global tipping points(临界点), according to the new Arctic Resilience Report. Those tipping points happen when a natural system quickly changes, leading to great effects on nearby ecosystems that might never be reversed(彻底转变)．
In the Arctic, they include growing vegetation that stops snow and ice and so absorbs more heat, and the release of methane(甲烷) from the Arctic as it warms. The report includes a range of different disastrous events that are likely to be produced by the warming poles.
The findings come just as climate scientists have warned that sea ice in the Arctic appears to be melting far more quickly than expected as the result of high temperatures.
Air over the Polar ice cap has been 9－12 degrees Celsius above average over the last four weeks, according to the Danish Meteorological Institute(DMI)．Through last week, temperatures reached melting point, putting them far above the expected temperature and serving as a dangerous signal for the sea ice there.
The temperature is “by far the highest recorded”，DMI researcher Martin Stendel told the AFP.“What we are observing is very unusual.”
At this time of year, the Arctic Ocean would be expected to start freezing up into sea ice again. But it isn’t happening.
“Not only was the ice not growing as it would normally, there was further melting due to warm air coming in，” he told the news agency.
That effect is being caused by a number of factors—not only climate change, but also temporary weather phenomena like El Niño. But those temporary(短暂的) things are being strengthened by climate change, which is the final driver of the melting sea ice, scientists said.

第一部分内容：晨诵晚读
Are Shark Nets Necessary?
为了防止鲨鱼对人类的攻击,一直以来澳大利亚的海岸线都设置防鲨网,但是研究发现该做法弊大于利。
Shark nets in place across Australia,specifically in New South Wales(NSW) and Queensland,to protect beachgoers should be dropped as they have caused more harm than good.
The measures①were carried out by some governments,including nets and traditional drum lines,and provided beachgoers with a false sense of safety.The study found the effectiveness of nets was difficult to evaluate②,while the significant damage they cause to other marine wildlife was clear.Researchers desire for non-deadly shark control measures such as eco barriers,which physically separate③swimmers from sharks,sonar(声呐) technology,and various shark-spotting techniques.
Researchers said while the risk of coming across a shark was rare,any shark-related deaths and injuries caught huge public and media attention.
One of the arguments in support of using shark nets is that just one shark-related death has been reported in Queensland since the 1960s.Similarly④,since the 1930s,NSW has had only one shark-related death.But there have been at least 13 people killed by sharks at beaches without nets on the NSW north coast over the past two years.
The Humane Society International’s head of campaigns,Nicola Beynon,said the government needed to move away from outdated methods⑤.“Deadly shark nets and drum lines are more than 50 years behind scientific and animal welfare standards for dealing with marine wildlife,” said Beynon.
The NSW Greens’ marine spokesman,Justin Field,said,“People are 100 times more likely to drown at the beach than to be killed by a shark in Australia.Therefore,millions of dollars going into the shark net program should be directed to observation⑥ towers for our lifeguards and improving the beach devices.”
①measure n.措施
②evaluate vt.评估
③separate vt.分开
④similarly adv.相似地
⑤method n.方法
⑥observation n.观察
The study found the effectiveness of nets was difficult to evaluate,while the significant damage they cause to other marine wildlife was clear.
译文:研究发现,防鲨网的有效性很难评估,而它们对其他海洋野生动物造成的重大损害则是显而易见的。
分析:本句总体上是一个并列句。The study found是第一个分句,while the significant damage...是第二个分句。在第一个分句中the effectiveness of nets was difficult to evaluate是宾语从句,在第二个分句中they cause to...是定语从句。
1.What do researchers focus on?
答案:Friendly shark control ways.
2.What do Nicola Beynon and Justin Field have in common?
答案:No shark nets are to be used.
