Perhaps you spotted them on La Cienega Boulevard, flying north by the thousands near the Westfield mall. Maybe you saw them in Santa Anita crossing a quiet street in a thick line. You may have even driven with hundreds of them along the 105 Freeway, where they violently beat their small wings as if they were trying to catch a flight at Los Angeles International Airport. People may mistake these black — and — orange insects for moths (飞蛾) or monarchs (黑脉金斑蝶)due to the appearance. Actually, they are called painted ladies, and these butterflies are flying by the millions across the state.

The migration((迁徙)itself is nothing new. What's unusual this year is the number of butterflies making the journey. James burg, the director of Palm Desert, came across a pack of butterflies while riding a bike lust week. "They were Hying with me, as I rode," he said. "It was absolutely magical. I felt like a Disney princess."

The painted lady's appearance is a welcome exception to California's current butterfly crisis. The number of butterflies in the state has been in a loss for decides, reaching historic lows in 2018. A monarch count led by the Xerces Society found only 28,129 of monarchs wintering along the California coast. That figure represents an 85% drop from the previous year and a 99.4% fall compared with 40 years ago. Other butterfly populations have been hit even worse.

No one is certain what is causing butterflies in California to disappear, but researchers have pointed several likely factors. They include the general loss of open spaces, which means fewer flowers and leaves for food, as well as changing agricultural practices that have reduced the number of butterfly-friendly plants along the edges of crop fields. The climate change plays a role, which produces higher temperatures that can dry plants out and make them uneatable.

Scientists say the reason for this year's painted ladies' appearance can be summed up in one word: rain. And more specifically, rain in the desert. “The more plants, the more butterflies," James Burg said.

You never see them, but they're with you every time you fly. They record where you are going, how fast you're traveling and whether everything on your airplane is functioning normally. Their ability to withstand almost any disaster makes them seem like something out of a comic book. They're known as the black box.

When planes fall from the sky, as a Yemeni airliner did on its way to Comoros Islands in the India ocean June 30, 2009, the black box is the best bet for identifying what went wrong. So when a French submarine (潜水艇) detected the device's homing signal five days later, the discovery marked a huge step toward determining the cause of a tragedy in which 152 passengers were killed.

In 1958, Australian scientist David Warren developed a flight-memory recorder that would track basic information like altitude and direction. That was the first mode for a black box, which became a requirement on all U.S. commercial flights by 1960. Early models often failed to withstand crashes, however, so in 1965 the device was completely redesigned and moved to the rear of the plane – the area least subject to（易遭受）impact – from its original position in the landing wells (起落架舱). The same year, the Federal Aviation Authority required that the boxes, which were never actually black, be painted orange or yellow to aid visibility.

Modern airplanes have two black boxes: a voice recorder, which tracks pilots' conversations, and a flight-data recorder, which monitors fuel levels, engine noises and other operating functions that help investigators reconstruct the aircraft's final moments. Placed in an insulated (隔绝的) case and surrounded by a quarter-inch-thick panels of stainless steel, the boxes can withstand massive force and temperatures up to 2,000℉. When submerged, they're also able to emit signals from depths of 20,000 ft.

Experts believe the boxes from Air France Flight 447, which crashed near Brazil on June 1, 2009, are in water nearly that deep, but statistics say they're still likely to turn up. In the approximately 20 deep-sea crashes over the past 30 years, only one plane's black boxes were never recovered.

1.What information could be found from the black box on the Yemeni airliner?

A．Data for analyzing the cause of the crash.

B．The total number of passengers on board.

C．The scene of the crash and extent of the damage.

D．Homing signals sent by the pilot before the crash.

2.Why was the black box redesigned in 1965?

A．New materials became available by that time.

B．Too much space was needed for its installation.

C．The early models often got damaged in the crash.

D．The early models didn't provide the needed data.

3.Why did the Federal Aviation Authority require the black boxes be painted orange or yellow?

A．To distinguish them from the colour of the plane.

B．To caution people to handle them with care.

C．To make them easily identifiable.

D．To obey international standards

4.What do we know about the black boxes from Air France Flight 447?

A．There is still a good chance of their being recovered.

B．There is an urgent need for them to be reconstructed.

C．They have stopped sending homing signals.

D．They were destroyed somewhere near Brazil.

Tips on Avoiding Traveling Crowds

If your chosen destination is a hot tourist spot，you are likely to be bothered by masses of tourists，noise and long line ups at your intended site visits. At this point you might wonder why you ever left home. Here are some tips to avoid the crowds and the frustrations that might otherwise ruin your trip.

Book tickets in advance

1. Smart travelers can avoid the queue when visiting abroad-the London Eye， Britain's Houses of Parliament，Italy's Vatican Museums，and the Louvre in Paris. You can keep cool with online ticket sales.

For shorter lines，fewer people，and better opportunities to interact and enjoy the attraction，stop by during the week. In many cases，you'll have the place to yourself. Take it one step further，and head to museums，galleries or tourism hot spots after 2 pm.4.

Watch the weather

Perhaps you’ve visited a restaurant and seen clear, water-filled bags hanging on the doors．You might ask，“What’s all this about? Some crazy new way to control temperature?A method of saving money on water containers?”While any effect on temperature is purely accidental，these hanging bags are all about driving pests away．

The water bag method to drive flies away has many supporters So how does the method drive flies away?Some insist the flies regard the clear liquid as the surface of a body of water．Others think the insect flies away at the sight of its own big reflection．But the most popular reasoning that exists among scientists is light refraction(折射)．

The insect’s fiead mostly consists of a pair of large complex eyes，each of which is made up of 3，000，to 6,000 simple eyes．These eyes can’t focus on objects like human eyes，instead they provide the fly with a mosaic(拼凑的)view of the world around them．A housefly bases its sense of direction on the sunlight．Some scientists believe that when these complex and sensitive eyes experience refracted light，the insect becomes confused and flies away．

Plenty of people don’t think water bags can keep flies away．Mike Stringham，a professor，conducted a 13-week field trial on two egg farms．He concluded those areas equipped with water bags actually experienced higher levels of housefly activity．Its purpose was to determine whether the water bags could be used to decrease fly populations on egg farms．

So do bags of water lower the number of houseflies around homes and restaurants? There are reasonable explanations that argue yes and strong evidence that proves no．Anyway，you can still find water bags hanging near restaurants and backyards across the globe．

1.Some restaurants hang water-filled bags on the doors to ____________．

A．control temperature　　　　 B．get hot water

C．save money　　　　　 D．drive flies off

2.What is considered more reasonable about the water bag method?

A．The light refraction of the bag drives flies away．

B．Flies are frightened away by their own reflections．

C．Flies mistake the bags as the surface of the waters．

D．The heat of the bags by the sunlight keeps flies off．

3.What is Paragraph 3 mainly about?

A．How many eyes a fly has．

B．How flies focus on objects．

C．Where flies can get sunlight．

D．Why refracted light keeps flies away．

4.We can describe the water bag method as“______________．”

A．practical　　 B．useless

C．controversial　　 D．Ridiculous

Have you ever run into a careless cell phone user on the street？Perhaps they were busy talking，texting or checking updates on WeChat without looking at what was going on around them. As the number of this new“species”of human has kept rising. They have been given a new name－phubbers (低头族)．

Recently，a cartoon created by students from China Central Academy of Fine Arts put this group of people under the spotlight. In the short film，phubbers with various social identities bury themselves in their phones. A doctor plays with his cell phone while letting his patient die，a pretty woman takes selfie in front of a car accident site，and a father loses his child without knowing about it while using his mobile phone. A chain of similar events eventually leads to the destruction of the world.

Although the ending sounds overstated the damage phubbing can bring is real.

Your health is the first to bear the effect and result of it.“Constantly bending your head to check your cell phone could damage your neck，”Guangming Daily quoted doctors as saying，“the neck is like a rope that breaks after long­term stretching.”Also，staring at cell phones for long periods of time will damage your eyesight gradually，according to the report.

But that’s not all. Being a phubber could also damage your social skills and drive you away from your friends and family. At reunions with family or friends，many people tend to stick to their cell phones while others are chatting happily with each other and this creates a strange atmosphere，Beijing Evening News reported.

It can also cost you your life. There have been lots of reports on phubbers who fell to their death，suffered accidents，and were robbed of their cell phones in broad daylight.

1.For what purpose does the author give the example of a cartoon in Para.2?

A. To advertise the cartoon made by students.

B. To inform people of the bad effects of phubbing.

C．To indicate the world will finally be destroyed by phubbers.

D．To warn doctors against using cell phones while treating patients.

2.Which of the following is NOT a risk a phubber may have?

A．His social skills could be affected.

B．His neck and eyesight will be gradually harmed.

C．He might get separated from his friends and family.

D．He will cause the destruction of the world.

3.Which of the following may be the author’s attitude towards phubbing?

A．Supportive.　　 B. Optimistic.

C.Opposed.　 　　 D. Objective.

4.What may the passage talk about next?
