1 . 阅读下面短文，在空白处填入1个适当的单词或括号内单词的正确形式。

Litter is everywhere，doing great harm     1     the environment and life on our planet.Jeff Kirschner，who wants to build a litter-free world，started a global community named Litterati     2       (settle)this problem.

The story began with his 6-year-old daughter.One day they were going on a hike when the girl noticed a     3     (break)plastic tub(浴盆)in a river.She said，“Daddy，that doesn’t go there.”That took Kirschner by surprise.He，like many adults，had become so used to the rubbish around them that he hadn’t given it a second look.    4     his daughter said reminded him of the serious problem our planet faces.

Jeff started to take       5    (act).He created Litterati，an app that makes it fun to pick up litter.The idea is       6    (fair) simple:Spot a piece of trash，take a photo，post the photo online and then put the litter into dustbins.

    7     (see)that Jeff was keeping a record of the positive impact he was having on the planet，people worldwide started participating.Up to now，over 2，500，000 photos posted by 3,500 people from over 40 countries     8     (find)their way to Litterati’s digital landfill.

Litterati is more than an app.It is a highly     9     (effect)solution to a pressing issue.Wherever you live，whatever you do and       10     you are，join Litterati to make the world a cleaner and healthier place to live in.

2 . Nowadays people tend to digitalise everything from watches to fridges. It seems you can choose any item labeled as “smart”.     1    . However, there are plenty that can be used to reduce emissions and save money.

If you’re a part of the digitalisation movement，you might be interested in the concept of smart homes. It means that every element of your house can be controlled from a panel on the wall or your phone.    2    . Use your mobile to power them on or off，and you may feel truly modern or truly lazy. Aside from the benefits of living a more comfortable life, this presents an opportunity to cut down on your electrical bills.

Electricity generation today represents 31% of total global fossil fuel use and around 40% of all energy-related CO₂ emissions.    3     It is considered as the first step to prevent global climate change. Connect a smart thermometer to the heating and cooling system and set a specific temperature at which the heating begins to work. Doing so, the room will be at a desired temperature when necessary and switches on a power-saving mode when not occupied. Similarly, by installing a CO₂ sensor, you can have an automated ventilation (通风) system.    4    .

In a 150,000m₂ office complex near Munich， called Campeon, energy costs of up to 117,067 Euro were saved after the use of environmental control devices this year. In this way, they are contributing to a large decrease in CO₂ emissions. Clearly, smart homes are about much more than just living a comfortable life.    5    .

A．It is actually about living a green life

B．Smart devices have been installed worldwide nowadays

C．It starts working only when CO2 concentrations reach a certain limit

D．There seem to be an ocean of such so-called “smart” inventions

E．Bearing this in mind, measures should be taken to make buildings more energy-efficient

F．Alternative energy must be discovered before the fossil fuel runs out in the future

G．This includes basics such as heating and lighting and many other appliances

3 . You might think that “global warming” means nothing more than a rise in the world’s temperature. But, rising sea levels caused by it have resulted in the first evacuation(撤离) of an island nation—the citizens of Tuvalu will have to have their homeland.

During the 20th century, sea level rose 8-12 inches. As a result, Tuvalu has experienced lowland flooding of salt water which has polluted the country’s drinking water.

Paani Laupepa, a Tuvaluan government official, reported to the Earth Policy Institute that the nation suffered an unusually high number of fierce storms in the past ten years. Many scientists connect higher surface water temperatures resulting from global warming to greater and more damaging storms.

Laupepa expressed dissatisfaction with the United States for refusing to sign the Kyoto Protocol, an international agreement calling for industrialized nations to reduce their greenhouse gas emissions(导致温室效应的气体排放), which are a main cause of global warming. “By refusing to sign the agreement, the US has effectively taken away the freedom of future generations of Tuvaluans to live where their forefathers have lived for thousands of years,” Laupepa told the BBC.

Tuvalu has asked Australia and New Zealand to allow the gradual move of its people to both countries.

Tuvalu is not the only country that is vulnerable(易受影响的) to rising sea levels. Maumoon Gayoon, president of the Maldives, told the United Nations that global warming has made his country of 311,000 an “endangered nation”.

B．sign an agreement with Tuvalu

C．allow Tuvaluans to move to the US

D．believe the problems facing Tuvalu were real

4 . Help Hermit Crabs

Hermit crabs are nature’s recyclers. They eat waste and help keep oceans and shores clean. Unlike other crabs, the hermit crab has a thin outer shell over its soft tail. This makes the hermit crab easy prey for hungry predators. Hermit crabs stay safe by living in old seashells. A hermit crab is picky; it tries on many shells until it finds one that fits just right. In recent years, however, many hermit crabs have had trouble finding their perfect homes. What is the problems There are not enough shells to go around!

One reason for the seashell shortage is that ocean water is not as clean as it once was. This has caused chemical changes to sea water. Some sea animals, like snails, are affected by these changes. Now there are fewer snails making shells. People visiting the beach often take shells home as souvenirs. This is another problem. Other people even take shells for their own pet hermit crabs! They do not realize that hermit crabs in the wild need those shells too.

Now people are working to solve this hermit crab housing shortage. They are teaching beach-Boers to leave seashells where they belong — at the seashore! Some people even make fake seashells that they hope the hermit crabs will like. For example, a group called Project Shelter invited people who visited their website to create different designs for hermit crab shells.

These designers had a lot to consider. What kind of material should be used to build a seashells. The material must be light enough for the hermit crab to carry, but strong enough to protect the crab from predators. The man-made shells could not contain glue or any other substance that might harm a hermit crab. Another challenge with building a hermit crab home was the opening to the shell. Too big would mean the crab would not feel safe. Too small would be uncomfortable, and the crab would not want to move in.

The Project Shelter shells are placed in the wild for hermit crabs to find. Lucky hermit crabs can move into these new dream homes.

5 . It's thought that around 5 trillion pieces of plastic are currently floating in our oceans.

Both mammals and fish benefit from clean oceans. It is reported that more than 8 million tons of plastic end up in our oceans every year, and nearly half of the plastic we produce is single-use only.

This shoe brand, however, is riding the wave of change and is on a mission to help clean up our waters and rid the sea of plastic bottles that can take up to 400 years to break down. Vivobarefoot's newest footwear uses recycled plastic materials and has created an education program that spreads awareness about how harmful plastic is for sea life.

Every pair of shoes is made up of 17 plastic water bottles taken from the ocean and turned into a sustainable, comfortable pair of shoes, which are also healthy for your feet. And while not everyone can take part in ocean cleanups, choosing little ways we can give back to our planet goes a long way.

Vivobarefoot's new products include a variety of high-performance styles such as casual sneakers, running shoes, and hiking boots. The brand hopes that its latest initiative（首创精神）will help lessen the indifference to pollution and how harmful it is for all living beings.

In the future, Vivobarefoot hopes to increase their production of shoes created from sustainable materials, and thankfully, they are now one of many brands that aim to increase environmentalism and educate communities on how global warming affects everyone.

This year, they'll add more recyclable and traceable materials into more than half of their production line, and they have plenty of creative developments in the works as well.

The shoes also have a health benefit. Based on the concept that wider, minimally designed shoes enable our foot to function at maximum potential, wearers also experience better balance and sensory input.

6 . My husband and I wanted desperately the instant transformation from typical consumers to eco-conscious people．We switched our light bulbs to CFL(compact fluorescent light)bulbs to conserve energy．We went about the house turning off lights and unplugging appliances that weren’t in use．But the rate of global warming exceeded our snail’s pace conversion to greenhood．So I pressed onward．

I decided to put veganism(素食主义)at the top of our agenda．Vegans refuse any animal flesh or commercial goods made from any animal byproducts such as milk or fats．All the family applauded this option except for my husband．Some kind of animal needed to sacrifice its dear life for his meal or it wash’t dinner．I cooked up a storm，struggling to prepare nutritious meals dominated by not-so-obvious vegan dishes like bean burritos and high-fiber vegetable stir-fry．It took a few days before he realized that he hadn’t been eating any meat．

“I feel like eating beef．”he announced．So that night，I took full advantage of a zucchini (一种南瓜)，cut it into chunky(粗大的)pieces and cooked them．Then I covered them with spices．My beef-starved husband had some and a curious look crossed his face．

“Where’s the beef?”

“Living peacefully somewhere on an open plain where it belongs．”

“I knew it”he murmured．“You’ve surely made great contributions to the boom in cattle.”His taste buds were developed completely around the flavor of every kind of animal：cattle，pigs，deer，lamb，chickens and ducks．Converting him was like feeding grass to a lion．

I’m all for preserving our planet，but what good would it do to save the earth for tomorrow’s generation if today’s died of starvation? The next day，we went out for burgers．I was very careful to place the paper bag into our recycling bin．

8 . Steven Stein likes to follow garbage trucks. His strange habit makes sense when you consider that he’s an environmental scientist who studies how to reduce litter, including things that fall off garbage trucks as they drive down the road. What is even more interesting is that one of Stein’s jobs is defending an industry behind the plastic shopping bags.

Americans use more than 100 billion thin film plastic bags every year. So many end up in tree branches or along highways that a growing number of cities do not allow them at checkouts(收银台). The bags are prohibited in some 90 cities in California, including Los Angeles. Eyeing these headwinds, plastic-bag makers are hiring scientists like Stein to make the case that their products are not as bad for the planet as most people assume.

Among the bag makers’ argument: many cities with bans still allow shoppers to purchase paper bags, which are easily recycled but require more energy to produce and transport. And while plastic bags may be ugly to look at, they represent a small percentage of all garbage on the ground today.

The industry has also taken aim at the product that has appeared as its replacement: reusable shopping bags. The stronger a reusable bag is, the longer its life and the more plastic-bag use it cancels out. However, longer-lasting reusable bags often require more energy to make. One study found that a cotton bag must be used at least 131 times to be better for the planet than plastic.

Environmentalists don’t dispute(质疑) these points. They hope paper bags will be banned someday too and want shoppers to use the same reusable bags for years.

1. What has Steven Stein been hired to do?

A．Help increase grocery sales.

B．Recycle the waste material.

C．Stop things falling off trucks.

D．Argue for the use of plastic bags.

2. What does the word “headwinds” in paragraph 2 refer to?

A．Bans on plastic bags.

B．Effects of city development.

C．Headaches caused by garbage.

D．Plastic bags hung in trees.

3. What is a disadvantage of reusable bags according to plastic-bag makers?

A．They are quite expensive.

B．Replacing them can be difficult.

C．They are less strong than plastic bags.

D．Producing them requires more energy.

4. What is the best title for the text?

A．Plastic, Paper or Neither

B．Industry, Pollution and Environment

C．Recycle or Throw Away

D．Garbage Collection and Waste Control

9 . We may think we're a culture that gets rid of our worn technology at the first sight of something shiny and new, but a new study shows that we keep using our old devices(装置) well after they go out of style. That’s bad news for the environment — and our wallets — as these outdated devices consume much more energy than the newer ones that do the same things.

To figure out how much power these devices are using, Callie Babbitt and her colleagues at the Rochester Institute of Technology in New York tracked the environmental costs for each product throughout its life — from when its minerals are mined to when we stop using the device. This method provided a readout for how home energy use has evolved since the early 1990s. Devices were grouped by generation — Desktop computers, basic mobile phones, and box-set TVs defined 1992. Digital cameras arrived on the scene in 1997. And MP3 players, smart phones, and LCD TVs entered homes in 2002, before tablets and e-readers showed up in 2007.

As we accumulated more devices, however, we didn't throw out our old ones. "The living-room television is replaced and gets planted in the kids' room, and suddenly one day, you have a TV in every room of the house," said one researcher. The average number of electronic devices rose from four per household in 1992 to 13 in 2007. We're not just keeping these old devices — we continue to use them. According to the analysis of Babbitt's team, old desktop monitors and box TVs with cathode ray tubes are the worst devices with their energy consumption and contribution to greenhouse gas emissions（排放）more than doubling during the 1992 to 2007 window.

So what's the solution（解决方案）? The team's data only went up to 2007, but the researchers also explored what would happen if consumers replaced old products with new electronics that serve more than one function, such as a tablet for word processing and TV viewing. They found that more on-demand entertainment viewing on tablets instead of TVs and desktop computers could cut energy consumption by 44%.

1. What does the author think of new devices?

A．They are environment-friendly.	B．They are no better than the old.
C．They cost more to use at home.	D．They go out of style quickly.

2. Why did Babbitt's team conduct the research?

A．To reduce the cost of minerals.

B．To test the life cycle of a product.

C．To update consumers on new technology.

D．To find out electricity consumption of the devices.

3. Which of the following uses the least energy?

A．The box-set TV.	B．The tablet.
C．The LCD TV.	D．The desktop computer.

4. What does the text suggest people do about old electronic devices?

A．Stop using them.	B．Take them apart.
C．Upgrade them.	D．Recycle them.

10 . 阅读下面短文，在空白处填入1个适当的单词或括号内单词的正确形式。

Diets have changed in China — and so too has its top crop. Since 2011, the country     1    （grow）more corn than rice. Corn production has jumped nearly 125 percent over     2     past 25 years, while rice has increased only 7 percent.

A taste for meat is     3     (actual) behind the change: An important part of its corn is used to feed chickens, pigs, and cattle. Another reason for corn's rise: The government encourages farmers to grow corn instead of rice     4     (improve) water quality. Corn uses less water     5     rice and creates less fertilizer(化肥) runoff. This switch has decreased     6     (pollute) in the country's major lakes and reservoirs and made drinking water safer for people.

According to the World Bank, China accounts for about 30 percent of total     7     (globe)fertilizer consumption. The Chinese Ministry of Agriculture finds that between 2005—when the government     8     (start) a soil-testing program     9     gives specific fertilizer recommendations to farmers - and 2011, fertilizer use dropped by 7.7 million tons. That prevented the emission(排放) of 51.8 million tons of carbon dioxide. China's approach to protecting its environment while     10     (feed) its citizens "offers useful lessons for agriculture and food policymakers worldwide." says the bank's Juergen Voegele.
