Scientists are preparing to launch the world's first machine to clean up the planet's largest mass of ocean plastic.
The experts believe the machine should be able to collect half of the detritus in the patch—about 40,000 metric tons— within five years. In the past few weeks they have been busy welding together giant tubes that will sit on the surface of the sea and form the skeleton of the machine, creating the largest floating barrier ever made.
The system, originally dreamt up by Mr. Slat, will be shipped out this summer to the Great Pacific Garbage Patch, between Hawaii and California, which contains estimated 1.8 trillion pieces of plastic. It will be the first ever attempt to tackle the patch since it was discovered in 1997.
Mr. Slat was 16 and still at school when he was diving in Greece and first saw for himself the amount of plastic polluting the sea. "There were more bags than fish down there," he recalls. Two years later he came up with a solution, quit university after six months and set up The Ocean Cleanup as a company. Mr. Slat says the first plastic to arrive on shore will be a major milestone. "We as humanity created this problem, so I think it's also our responsibility to help solve it," he says.
The Great Pacific Garbage Patch (GPGP) covers an area of 1.6 million square kilometers and contains at least 79,000 tons of plastic, research found last month. Most of it is made up of "ghost gear"—parts of abandoned and lost fishing gear, such as nets and ropes—often from illegal fishing vessels.
Ghost gear kills more than 100,000 whales, dolphins and seals each year, according to scientific surveys. Seabirds and other marine life are increasingly being found dead with stomachs full of small pieces of plastic. Creatures eat plastic discarded in the sea thinking it's food but then starve to death because they are not feeding properly. Others are trapped and die of starvation or are strangled or suffocated by ghost gear.
1. What does the underlined word in the second paragraph probably mean
A. Waste.
B. Ocean.
C. System.
D. Machine.
2. Which one makes up most of the garbage in Pacific from the passage
A. Fishing vessels.
B. Dolphins and seals.
C. Giant tubes.
D. Abandoned fishing gear.
3. Why do some creatures in The Great Pacific Garbage Patch die of starvation
A. Because they are killed by ghost gear.
B. Because they are suffocated by ghost gear.
C. Because they don't like eating plastic.
D. Because they are not feeding properly.
4. What is the main idea of the passage
A. A report about the death of marine life.
B. News about the first machine to clean up ocean plastic.
C. Information about ocean plastic.
D. The reason for inventing a machine.

3.答案：a
解析：考查冠词。句意:我们已经看到,两国之间的对外贸易急剧下降。此处drop意为"下降;下跌;减少",为可数名词;此处表泛指,sharp的发音以辅音音素开头,故填a。
4.答案：why
解析：考查表语从句。句意:我在网上寻求了公众的帮助。那就是我为什么很快就找到了我的宠物狗。空处引导表语从句,且根据语境可知,此处表示"为什么",故填why。

7.答案：directly
8.答案：boring
9.答案：various

三、
答案：1-4ADDB
解析：1.词义猜测题。根据第二段中的"collect half of..." 和第四段中的"amount of plastic polluting the sea"以及第五段中的"parts of abandoned and lost fishing gear"可知,画线词意为“废物”。
2.细节理解题。根据第五段中的"Most of it is made up of ' ghost gear' —parts of abandoned and lost fishing gear, such as nets and ropes—often from illegal fishing vessels."可知, 太平洋里的大部分垃圾都是由废弃的渔具组成的。故选D。
3.细节理解题。根据最后一段中的“but then starve to death because they are not feeding properly ”可知,太平洋大垃圾带里的一些生物死于饥饿是因为它们不能正常进食。故选D。
4.主旨大意题。根据全文内容可知,第一段是新闻的重点信息,后面段落是对该新闻信息的详细描述,这是新闻报道类文章的特点。
四、
答案：①when ②had met ③off/out ④frightened ⑤a ⑥to start ⑦would be caught ⑧teeth ⑨running
⑩closer
解析：①考查固定句式。句意:在7月的一个阳光明媚的温暖的下午,小学教师麦克·霍兰正独自骑车从家去阿拉斯加,突然他听到身后传来急促而响亮的呼吸声。
②考查时态。句意:事实上,就在5分钟前, 他刚刚从一个加油站出发,遇到了一些骑自行车的人,但是现在没有人能帮助他。结合句意可知,此处指“过去的过去”, 所以用过去完成时,故答案为had met。
③考查固定词组。set off/out为固定搭配,意为 “出发,开始”,故答案为off/out。
④考查过去分词。句意:但一分钟后,它又出现在他身边,让他更加害怕。固定结构:make +宾语+过去分词。此处是过去分词做宾语补足语,故答案为frightened。

⑥考查动词不定式。此处是动词不定式做状语,表示出乎意料的结果。故答案为to start。
⑦考查过去将来时的被动语态。句意:他知道一旦他上了山,他就会被抓住,狼会撕咬他的肉。 once引导了条件状语从句,主句的主语he和catch之间是一种被动关系,应用过去将来时的被动语态,故答案为would be caught。
⑧考查名词复数。结合句意可知此处用名词复数形式,故答案为teeth。
⑨考查现在分词。句意:他们也发现了这一场景,认为是一只狗和一个骑自行车的人一起跑。此处是现在分词做后置定语,故答案为running。
