高三英语单项填空困难题查看答案及解析

With a rise in the number of allergies and worries over exposure to chemicals, more people are looking for alternative ways to clean their homes. To this end, some people are turning to the use of garbage enzyme (酶)--a concentrated liquid produced from fruit and vegetable waste. Garbage enzyme can be easily produced in the home, and has many uses, including as a cleansing agent, insect killer and even shampoo.

At the same time, it is hoped that the production and use of garbage enzyme will help reduce household waste and encourage people to take the initiative in sorting their trash.

The concept of using home-produced enzymes entered China several years ago when a special bucket imported from Japan was promoted by some health experts as a means of making healthy drinks. While the effectiveness of the enzyme drink remains unproven, garbage enzyme has been shown to be effective as an agent for cleaning toilets and floors, and as a fertilizer for plants.

Making wet garbage into an enzyme solution has been practiced in Southeast Asian countries for decades, greatly reducing household waste and protecting the environment by reducing the use of bleach (漂白剂) and other strong chemicals. Many people have realized that chemicals do harm to human body and the more garbage enzyme they make, the more good it does to the environment.

Any reduction in the volume of household garbage will benefit the city. Shanghai produces the largest amount of garbage than any other city in China. It is also home to the largest refuse landfill in Asia, the Laogang Refuse Landfill in Pudong New Area, which occupies a total area of about 30 square kilometers. It is struggling to accommodate all of the city's garbage, with a fifth phase under construction. The landfill and its surrounding areas are heavily polluted, something that nearby residents have been complaining about for years. The process of making enzyme solution consumes wet garbage. This means residents don't produce wet garbage after they start to make garbage enzyme. They even find the amount of wet garbage produced by their families is insufficient, so that they have to ask for garbage from their neighbors. Another advantage is that producing garbage enzyme encourages people to think more about garbage separation — something the local government has been trying to encourage but which still is not practiced by some residents.

1.Which of the following belongs to the usage of garbage enzyme?

A.Making plants more fragrant.

B.Creating materials to clean houses.

C.Producing effective healthy drinks.

D.Reducing the amount of dry garbage.

2.What is the writer's attitude toward garbage enzyme?

A.Disapproving. B.Ambiguous. C.Favorable. D.Skeptical.

3.How will garbage enzyme possibly affect people in the future?

A.It will force people to ask for more garbage from their neighbors.

B.It will prevent people from using chemicals to clean their houses.

C.It will shelter people from household garbage pollution for good and all.

D.It will make people take garbage separation seriously before dumping it.

4.What is the passage mainly about?

A.The threat of constructing more landfills.

B.How to classify garbage wisely and practically.

C.How to make garbage enzyme at home successfully.

D.The practice of turning leftover into a household product.

Can animals be artistic? Painting and music are part of efforts to keep animals happy at the Smithsonian’s National Zoo.

A sloth bear (长毛熊) called Francois is one of the National Zoo’s artists. He began his artistic career two years ago. Francois has a very unusual way to paint. He uses his breathing to paint. His zookeeper, Stacey Tabellario, says that although the technique may look strange, it is actually a very natural behavior for sloth bears. The zookeepers fill one of those tubes full of paint and ask them to breathe through it. And they blow all of the paints onto the canvases (画布), making these really cool paintings.

Animal artists come in all shapes and sizes at the Zoo. They use many kinds of techniques to create their works of art. Apes use paintbrushes. Many use their paws or claws—much like a human painter who would use his or her hands.

Stacey Tabellario says Francois seems to enjoy expressing himself through his art. “When I set up the materials for painting activity, he comes and sits next to them and waits until they are ready for painting. He does that every time. I also see where his eyes go. He does see the paints come out of the tube and land on the canvas.”

But not every animal wants to paint. Music is another part of the arts enrichment program. Physically and mentally stimulating activities are an important part of the daily care of the animals. Trainers have a lot of tools, from tablet computer to small toys.

Kenton Kerns says the program helps the animals and the zookeepers in many ways. Every interaction between keepers and their animals creates some sort of connections. The one-of-a-kind works of art created by the animals are popular with zoo visitors. Many are sold at the zoo’s fund-raising events.

1.From Paragraph 2, we can learn that ________.

A. Francois is a two-year-old artist at the National Zoo

B. Francois can make fantastic paintings with paintbrushes

C. Francois, way to paint is an unnatural behavior for sloth bears

D. Francois paints by blowing the paints in the tubes onto the canvas

2.According to the passage, the apes paint by ________.

A. blowing the tubes full of paints

B. using their hands directly

C. using some tools

D. walking on the canvas

3.From the last paragraph, we can learn the works of art created by the animals ________.

A. can be sold at a high price

B. are mainly popular with the kids

C. create higher prices than the artists

D. can be bought at the zoo’s fund-raising events

4.What’s the main idea of the passage?

A. Zoo animals show artistic side.

B. Painting and music are useful in the zoo.

C. Animals enjoy painting.

D. Animals need enrichment too.

“Don't worry if you have problems!” It is easy to say until you are in the midst of a really big one．The only people who don't have troubles are gathered in little neighborhoods．Most communities have at least one．We call them cemeteries．If you're breathing, you have difficulties．It's the way of life．And believe it or not, most of your problems may actually be good for you! Let me explain．

Maybe you have heard the Great Barrier Reef, stretching some 1,800 miles from New Guinea to Australia．Tour guides regularly take visitors to view the reef．

On one tour, a traveler asked the guide an interesting question．"I notice that the lagoon （泻湖） side of the reef looks pale and lifeless, while the ocean side is vibrant and colorful," the traveler observed．Why is this?

The guide gave an interesting answer, "The coral around the lagoon side is in still water, with no challenge for its survival．It dies early．The coral on the ocean side is constantly being tested by wind, waves and storms．It has to fight for its survival every day．As it is challenged and tested, it changes and adapts．It grows healthy．It grows strong．And it reproduces．"

Then he added, “That's the way it is with every living organism．”

That's how it is with people．Challenged and tested, we come alive! Like coral pounded by the sea, we grow．Physical demands can cause us to grow stronger．Mental and emotional stress can produce tough-mindedness and resiliency．Spiritual testing can produce strength of character and faithfulness．So, you have problems?
