【題目】 Somewhere between 40,000 and 110,000 tons of plastic waste produced by Americans ends up in the ocean, according to a study published in the journal Science.

It's difficult to point out where all that waste comes from, and researchers think that much or most of it probably comes from the nation's seriously-populated coasts. But there's also evidence that the nation's inland waterways serve as a passage for plastic to travel thousands of miles into the oceans.

While researchers have documented plastic and human trash floating in the world's oceans, there has been relatively little attention paid to plastics in rivers, streams and lakes. "To my knowledge, no one has studied particular routes, with the exception of places like L.A, and Baltimore Harbor where there are measures in place to prevent trash in rivers from entering the ocean." said Kara Lavender Law, an oceanographer.

The few studies that exist, however, suggest that it may be a huge problem. A 2011 study of two southern California urban rivers---including Santa Ana River---found that every square meter of water contained from 125 to 819 pieces larger than 4.75 millimeters. Another survey of the Meuse River, which flows 575 miles through France, Belgium and the Netherlands to the North Sea, found that it contained 70,000 pieces of plastics per square meter of water, about 500 of which were roughly an inch or bigger in size.

If there's anything positive in this, it's you that can do something, at least on a personal level, to reduce the amount of plastic that goes into the oceans. "Put trash where it goes." said Jenna Jambeck, an associate professor of environmental engineering at the University of Georgia. "Use reusable items---bags, cups and bottles---to reduce waste."

Finally, Jambeck urges people to pick up litter along waterways, and record it with a phone app called the Marine Debris Tracker. The data you provide can help scientists to get a better handle on the trash problem.

1According to the text, the least polluted place might be __________.

A.Santa Ana RiverB.Meuse River

C.Baltimore HarborD.The North Sea

2How does the author prove plastic waste in rivers is a huge problem?

A.By referring to experts' views.B.By listing statistics.

C.By making comparisons.D.By following time order.

3What does Jenna Jambeck advise us to do?

A.Make use of plastic items.B.Reduce the size of waste we throw away.

C.Stay positive about the oceans' future.D.Start from small things to deal with waste.

【答案】

【解析】

這是一篇說明文。研究顯示,美國人產(chǎn)生的4萬到11萬噸塑料垃圾流入海洋,很難指出所有垃圾來及哪里,但是研究人員認(rèn)為,很多或大部分可能來自這個(gè)國家人口稠密的海岸。但也有證據(jù)表明,國家的內(nèi)河航道是塑料經(jīng)過數(shù)千英里進(jìn)入海洋的通道。建議人們從我作起,保護(hù)環(huán)境。

1

細(xì)節(jié)理解題。根據(jù)第三段To my knowledge, no one has studied particular routes, with the exception of places like L.A, and Baltimore Harbor where there are measures in place to prevent trash in rivers from entering the ocean.可知,據(jù)我所知,沒有人研究過特定的路線,除了洛杉磯和巴爾的摩港,這些地方有措施去防止河流中的垃圾進(jìn)入海洋。因此,污染最少的地方可能是巴爾的摩港。故選C

2

推理判斷題。根據(jù)第四段A 2011 study of two southern California urban rivers---including Santa Ana River---found that every square meter of water contained from 125 to 819 pieces larger than 4.75 millimeters. Another survey of the Meuse River, which flows 575 miles through France, Belgium and the Netherlands to the North Sea, found that it contained 70,000 pieces of plastics per square meter of water, about 500 of which were roughly an inch or bigger in size.可知,2011年對(duì)南加州兩條城市河流(包括Santa Ana河)的研究發(fā)現(xiàn),每平方米含125819塊垃圾,大于4.75毫米。另一項(xiàng)對(duì)Meuse河(流經(jīng)法國、比利時(shí)和荷蘭575英里到達(dá)北海)的研究發(fā)現(xiàn),每平方米水中含有70000塊塑料,其中大約有500個(gè)大約一英寸或更大。根據(jù)以上內(nèi)容可以判斷出,作者通過列舉數(shù)據(jù),證明河流中的塑料垃圾是個(gè)大問題。故選B。

3

細(xì)節(jié)理解題。由最倒數(shù)第二段... at least on a personal level, to reduce the amount of plastic that goes into the oceans. Put trash where it goes.至少在個(gè)人層面上,減少流入海洋的塑料量!袄旁谒鼞(yīng)該放的地方。以及由最后一段Finally, Jambeck urges people to pick up litter along waterways, and record it with a phone app called the Marine Debris Tracker. The data you provide can help scientists to get a better handle on the trash problem.可知,最后,Jambeck敦促人們撿沿河的垃圾,用一個(gè)叫Marine Debris Tracker的手機(jī)應(yīng)用程序記錄下來。你提供的數(shù)據(jù)可以幫助科學(xué)家更好地處理垃圾。由此可以看出,Jenna Jambeck建議人們從小事做起,來處理垃圾。故選D。

【題目】Directions: Complete the following passage by using the sentences given below. Each sentence can be used only once. Note that there are two more sentences than you need.

Possible Limitations of Online Learning

If eLearning, however, is not based on solid instructional design theories and models it may lead to the following limitations:

1. It may be a "solo" act.

It is true that, although online learning might be convenient and flexible, it is also a solo act. It will not be easy for all of your learners to feel comfortable when participating in online discussions and engaging more actively with their online instructors or their virtual classmates. Some people absolutely need personal contact with their educators or trainers in order to learn successfully. Furthermore, some types of learning problems may be difficult to be addressed online, and some questions can be lost in a sea of requests and inquiries. 1

2. 2

However hard we try to fully transfer human communication to online platforms, however natural it seems to form relationships behind computer screens, a virtual environment is just not human. Nothing can replace human contact. Besides, using a computer or a tablet all the time can cause poor vision, strain injuries, and other physical problems. Consider sending guidelines about right sitting posture, desk height, etc. along with your eLearning course; it might be very useful to your audience.

3. It requires self-discipline.

If your eLearning audience lacks self-discipline, it is unlikely that they will be motivated to self study. Traditional learning and training have the benefit of easily tracking both progress and falling behind. 3

4. Possible lack of control.

However carefully you design your eLearning course, there is no guarantee that your messages will get across. You offer your learners control over their eLearning experience, but are they going to use it effectively? There is always the risk of your learners just going through the material without paying any attention. 4 Unless you know exactly what you’re doing with new technologies, it is very likely that you overwhelm or distract your audience.

Creating effective online learning courses requires knowledge, time, experience, commitment, great communication skills, and a true passion for learning. If you’ve got all that, then be sure that the advantages of your online training outweigh its limitations.

A.It may be impersonal.

B.If your eLearning content is not built to make the most of the medium it will easily become disengaging.

C.This sometimes makes learners feel they lack support and reassurance.

D.It may harm your mental health.

E.Online learning requires some IT literacy, yet not every one of your learners has much experience of computers.

F.This works for many learners as well, as some people prefer their progress to be closely monitored in order to perform.

【題目】閱讀下面材料,根據(jù)其內(nèi)容和所給段落開頭語續(xù)寫兩段,使之構(gòu)成一篇完整的短文。續(xù)寫的詞數(shù)應(yīng)為150左右。

“Mommy ,don't go,”my three-year-old son screamed as I walked to the door. My fifteen-year-old leaned against the kitchen counter with his arms folded across his chest ,not screaming,but glaring at me as I pulled his little brother off my leg.

“Are you mad at me too?”

“You spend all your time taking care of other people's kids,but what about us?”Dylan left angrily.

I was shocked and a little hurt. How could my own child not understand that the work I was doing was saving live? Then the answer hit me. He didn't know bemuse he had never seen what Healing the Children actually did. Dylan had heard the sores of sick children, but had never once looked into the eyes of a child and understood the hard truth-that without our help, the child would likely die.

“Get dressed. You are going with me.”I said.

I spend the drive explaining the case of Hector to my son, who pretended to ignore me the entire time.“He's seven, only weighs thirty pounds and is very sick. He has a heart condition called Tetralogy of Fallot, which could kill him. It is a miracle(奇跡) that he is still alive. ”

I went on to explain that it took a team of volunteer medical staff to get Hector to the hospital from his remote village and care for him while he was there. Still, Dylan seemed unimpressed.

We stopped at a convenience store for water and snacks. Dylan had one large and one small Slurpee (思樂冰飲料). He said the small one was for Hector. I doubted whether the little guy would be able to drink it, but remained silent. This was the first interest Dylan had shown in being there. I wasn't about to ruin it.

I stopped at the nurse's station to check on Hector's progress while Dylan went to his room. Our patient was recovering physicallybut the nurse was concerned that Hector was struggling emotionally. She said “Kids usually bounce back fast, but he hardly speaks and never smiles.”

【題目】 My mother always told me, “You should explore your own country before stepping out into the world. ”However, it seems like a tough mission to travel all across its expansive surfaces. But luckily for me, Via Rail Canada offered youths between the ages of 18 and 25 the chance to ride the train across Canada for the month of July. The ticket was a bargain $150. My best friends Trevor, Joel and Jeremy and I immediately jumped at the opportunity and secured four tickets on the great Canadian railroad.

For a group of 20-year-olds, this was like the first flight of young birds from the nest. When we approached the train station in the morning, our 22-day adventure from Sudbury to Vancouver was to begin. Eyes baggy from lack of sleep, we jumped on board as if it was the train to Hogwarts in Harry Potter. Although the thought of three full days on those tracks covering close to 3, 000 kilometres crushed our spirits a little, what happened next caught us by surprise.

The three days on board turned into a summer camp on rails. At night, we would climb up the glass-domed train car, which gave us a scenic view of the starry night sky, untouched by the harmful light pollution. Before we knew it, the warm sun rays beating down on our faces woke us up for another day on the rails. To my surprise, a sea of golden grain fields dominated the landscape we were in the Canadian Prairies.

Another day slipped away and we set up for another night in the dome. And this time we were greeted by night sky painted by a fantastic thunderstorm. Lightning was striking at an incredible rate. The spectacular and memorable light show left everyone in the glass bubble in complete disbelief.

Arriving in the Rocky Mountains was one of the most surreal experiences of my life. Before the train adventure, if I could have skipped the travel and arrived at the destination, I would have. That is no longer true. I’ve learned that the journey can be more enjoyable than the destination.

1What has made the author’s train adventure across Canada a reality?

A.The encouragement given by his mother.B.The appeal of the scenic views in the country.

C.The discount ticket offered by Via Rail Canada.D.His great courage to challenge a tough mission.

2What can we infer about the young people from Paragraph 2 ?

A.They were excited about the coming train journey.

B.They left their parents for the first time in their life.

C.They never thought of having a train adventure.

D.They were hooked by the magic story of Harry Potter.

3What does“the glass bubble”in the fourth paragraph refer to?

A.A brain in lack of imagination.B.The glass-domed train car.

C.A summer camp on the train.D.The sightseeing bus.

4What did the author learn from the train adventure across Canada?

A.Opportunities are hard to get.B.Enjoying a journey counts a lot.

C.Splendid scenery attracts young people.D.The traveling experience is not real to him.
