Disposing(处理)of waste has been a problem since humans started producing it.As more and more people choose to live close together in cities,the waste-disposal problem becomes increasingly difficult.
During the eighteenth century,it was usual for several neighboring towns to get together to select a faraway spot as a dump site.Residents or trash haulers(垃圾拖运者)would transport household rubbish,rotted wood,and old possessions to the site.Periodically some of the trash was burned and the rest was buried.The unpleasant sights and smells caused no problem because nobody lived close by.
Factories,mills,and other industrial sites also had waste to be disposed of.Those located on rivers often just dumped the unwanted remains into the water.Others built huge burners with chimneys to deal with the problem.
Several facts make these choices unacceptable to modern society.The first problem is space Dumps,which are now called landfills,are most needed in heavily populated areas.Such areas rarely have empty land suitable for this purpose.Property is either too expensive or too close to residential neighborhoods.Long-distance trash hauling has been a common practice but once farm areas are refusing to accept rubbish from elsewhere,cheap land within trucking distance of major city areas is almost nonexistent.
Awareness of pollution dangers has resulted in more strict rules of waste disposal.Pollution of rivers,ground water,land and air is a price people can no longer pay to get rid of waste.The amount of waste,however,continues to grow.
Recycling efforts have become commonplace,and many towns require their people to take part.Even the most efficient recycling programs,however,can hope to deal with only about 50 percent of a city’s reusable waste.

You can’t always predict a heavy rain or remember your umbrella. But designer Mikhail Belyaev doesn’t think that forgetting to check the weather forecast before heading out should result in you getting wet. That’s why he created Lampbrella, a lamp post with its own rain sensing umbrella.

The designer says he came up with the idea after watching people get wet on streets in Russia. “Once, I was driving on a central Saint Petersburg street and saw the street lamps lighting up people trying to hide from the rain. I thought it would be appropriate to have a canopy(伞蓬)built into a street lamp,” he said.

The Lampbrella is a standard-looking street lamp fitted with an umbrella canopy. It has a built-in electric motor which can open or close the umbrella on demand. Sensors(传感器)then ensure that the umbrella offers pedestrians (行人) shelter whenever it starts raining.

In addition to the rain sensor, there’s also a 360° motion sensor on the fiberglass street lamp which detects whether anyone is using the Lampbrella. After three minutes of not being used the canopy is closed.

According to the designer, the Lampbrella would move at a relatively low speed, so as not to cause harm to the pedestrians. Besides, it would be grounded to protect from possible lightning strike. Each Lampbrella would offer enough shelter for several people. Being installed at 2 meters off the ground, it would only be a danger for the tallest of pedestrians.

While there are no plans to take Lampbrella into production, Belyaev says he recently introduced his creation to one Moscow Department, and insists this creation could be installed on any street where a lot of people walk but there are no canopies to provide shelter.

1.For what purpose did Belyaev create the Lampbrella?

A. To predict a heavy rain.

B. To check the weather forecast.

C. To protect people from the rain.

D. To remind people to take an umbrella.

2.What do we know from Belyaev’s worlds in Paragraph 2?

A. His creation was inspired by an experience.

B. It rains a lot in the city of Saint Petersburg.

C. Street lamps are protected by canopies.

D. He enjoyed taking walks in the rain.

3.Which of the following show how the Lampbrella works?

A. motor→canopy→sensors                                 B. sensors→motor→canopy

C. motor→sensors→canopy                                  D. canopy→motor→sensors

4.. What can be inferred from the last paragraph?

A. The designer will open a company to promote his product.

B. The Lampbrella could be put into immediate production.

C. The designer is confident that his creation is practical.

D. The Lampbrella would be put on show in Moscow.

 

Animal moms are great moms. You might be surprised at some of these moms.

Octopuses (章鱼)

The mother octopus lays about 50,000 eggs. For about 300 days, she stays with the eggs, cleans them and protects them. She does not leave to feed. However, this animal mom dies as soon as the eggs are hatched (孵化).

Crocodiles(鳄鱼)

A crocodile mother puts a lot of time and effort into raising her babies. She starts by building a nest (巢), which she guards for over two months! When the eggs are ready to hatch, the young crocs call out to their mother, who digs them out and helps them hatch. She then carries them in her mouth down to the water, where she will guard them for several more weeks or months until they learn to hunt on their own.

Bats (蝙蝠)

Bats become moms by hanging head up in a cave, giving birth. Catching the youngster before it can fall to the ground below, she puts it in a pouch (育儿袋). Bat moms may carry babies with them when feeding for the first few days. As the little bats get bigger and heavier, moms help them hang on the wall of their caves and return often to feed them. It continues for about three weeks, until the babies are grown up and able to fly on their own.

Koalas (考拉)

The animal mom gives birth after a pregnancy (怀孕期) of only 35 days. The hairless baby climbs into its mother’s pouch and lives there for another five months. When the little koala is between five and eight months old, it leaves the pouch for short periods of time but returns for safety. Once it is too big to return to the pouch, it will climb onto its mother’s back and ride there until it is about 12 months old.
