Floating mountains in the ocean are better known as icebergs (冰山). Icebergs are 1 (mass) of freshwater ice that have broken from a glacier (冰川) or polar ice sheet. Most icebergs are formed around Antarctica and Greenland.

Icebergs 2 (see) today began thousands and thousands of years ago. They began as flakes of snow falling on land. Over the years, more and more snow fell. The snow on 3bottom was crushed (压碎) because snow on top was packing it down. Years of 4(melt) and freezing formed layers of ice thousands of feet thick. These sheets of ice are called glaciers. During the warmer weather in spring 5 summer, pieces of ice break off from glaciers. The broken pieces of ice fall into the water and become icebergs.

Icebergs vary 6 size. The largest iceberg ever recorded was the size of the state ofRhode Island in the United States. The 7 (tall) iceberg stood 550 feet above the ocean. That’s about the size of the Washington Monument in Washington, D. C.

Icebergs can be very 8 (danger) to ships traveling near them because only one-eighth of an iceberg 9 (be) above water. This means that the rock-hard ice is much larger underneath. Captains taking 10(they) ships around an iceberg may miscalculate the size of the iceberg.

【解析】

本文为说明文。文章主要说明冰山的一些特点以及注意事项。

1 考查固定搭配。句意:冰山是冰川或极地冰盖上破碎的大量淡水冰。masses of 为固定搭配,意为“许多的,大量的”,故填masses

2考查过去分词作定语。句意:今天看到的冰山始于数千年前。分析句子可知,空格处在句中作定语,因为Greenland Icebergs 和动词see二者是被动关系,要用过去分词作后置定语,故填seen

【题目】 E-cigarettes lead to as many lung diseases as tobacco products, a new study has found. The report from the University of North Carolina at Chapel Hill compared saliva (唾液) samples from tobacco smokers, e-cigarette smokers and nonsmokers. Researchers found that e-cigarette smokers were likely to develop dangerous proteins associated with lung diseases. The study adds to a growing body of evidence proving that e-cigarettes might not be the perfect alternative smokers addicted to tobacco are looking for.

Last year a Surgeon General’s report claimed that the use of e-cigarettes among a certain group of people jumped 900 percent from 2011 to 2015 and more studies were carried out to research their side effects. That same year, the FDA put e-cigarettes in the tobacco products the administration monitors.

Previous research from UCLA has proven that e-cigarettes can cause lifelong damage to one’s heart, and that one puff (吸一口烟) of an e-cigarette is all it takes to increase one’s risk of having a heart attack. For the new study UNC researchers observed 15 e-cigarette users, 14 cigarette smokers and 15 nonsmokers. The study revealed that e-cigarette smokers have raised levels of NET-related proteins in their airways, the increased levels of which can lead to lung illnesses, making it difficult for patients to breathe.

Study author Dr Mehmet Keismer said, “There is confusion about whether e-cigarettes are ‘safer’ than cigarettes because the potential adverse effects of e-cigarettes are only beginning to be studied. Our results suggest that e-cigarettes might be just as bad as cigarettes.” Dr Keismer also stressed that e-cigarettes come with their own harmful risks along with those linked to tobacco, which challenges the concept that switching from cigarettes to e-cigarettes is a healthier alternative.

A citizen named Dyclna said, “The e-cigarettes probably make you cough less, but nobody gives a warning about your lungs. For producers, it’s just a money thing — it’s just about getting profits from it. The problem is that our government just stands there with its hands behind the back.”

1Why did the FDA list e-cigarettes into monitored products?

A.It might realize the harm of them.

B.It wanted to improve their quality.

C.It aimed to reduce their illegal sales.

D.It might be warned by the government.

2What harm does the increased level of NET do to people?

A.Leading to weight gain.B.Spoiling people’s appetite.

C.Making breathing hard.D.Speeding people’s heartbeat.

3What does Dyclna mainly want to express?

A.E-cigarettes are safer than regular ones.

B.E-cigarettes can only benefit few people.

C.Producers make a high profit from e-cigarettes.

D.Governments are to blame for e-cigarettes’ consumption.

4What is the best title for the text?

A.E-cigarettes: A new way of smoking.

B.E-cigarettes: A better way than tobacco?

C.E-cigarettes: The harmful proteins it produces.

D.E-cigarettes: The urgent need of government control.

【题目】 People feel good about recycling, maybe even more so when it comes to electronics. While electronics recycling isn't bad, making it a panacea(万能药) for the e-waste problem we currently have certainly is. Unfortunately, that's how we think of recycling — and companies to jump on that trend to appear more “green”.

A case in point: Apple. In 2016, there was lots of report on Liam, a robot able to dismantle(拆卸) an iPhone in just 11 seconds — a good way to recycle 1.2 million units a year. That sounds amazing until you take into account the fact that Apple had actually sold 231 million new iPhones the year before. Liam, actually, is the perfect symbol for recycling in the field of high-tech: a drop of green water in an ocean of pollution.

According to a recent UN report, the US produces about 6.3 million tons or 14% of the world's electronic waste. Worldwide, almost 45 million tons of electronic waste were produced in 2016. Among them, only 20% had been recycled in some shape or form. The remaining 80% made its way to a more environmentally damaging end at the landfill(垃圾填埋场).

Of course, we can say it's time to double our recycling efforts. However, the huge amount of e-waste is impossible to cope with. The UN report points out that while there is an increased focus on recycling today compared to the past, the effort to reuse used devices simply can't keep pace with the high consumption rates for new devices.

In their environmental responsibility report, Apple admits that 77% of the carbon footprint of their electronics comes from their manufacture, versus(相对于) 17% comes from its actual use. The environmental effect of replacing a device, even if it is recycled after, remains significant.

1Which of the following can best describe Liam?

A.It's useful but can't make a big difference.

B.It's energy-saving but too expensive.

C.It's well-made but won't become popular.

D.It's advanced but impractical.

2What caused the e-waste recycling problem?

A.Few high-tech companies.

B.Not enough recycling efforts.

C.High demand for new electronics.

D.Difficult recycling processes.

3What does the author think of the electronics recycling?

A.It is very effective.

B.It is quite good.

C.It is environmentally damaging.

D.It is far from “green” recycling.

4What can be the best title for the text?

A.A Recent UN Report on E-Waste Problem

B.The Limitation of Electronics Recycling

C.A Good Way to Cope With E-Waste

D.The Responsibility for Apple to Decrease E-Waste
