Migration (迁徙), is a long journey carried out by some birds to other areas where they hope to find more food and a warmer place to spend the winter. A hundreds or thousands of miles' journey is actually difficult and dangerous. So why do birds migrate ① _____ However, it all comes down to survival.
Migrating for a Meal
For all birds, one of the main driving forces behind migration is food shortage. If all birds were to stay in the same warm regions all the year round, food would become lacking and producing their young would be less successful. As food resources are rich in the north each spring, millions of birds migrate there for the food supplies. ②_____
Migrating for Families
Over thousands of years, birds have evolved different migration patterns, timing a destination to fly around the world to produce their young. Birds take advantage of a wide variety of suitable conditions to raise their young. ③_____
Migrating for Climate
Birds have evolved different types of feathers to survive different climates. ④_____ So many birds leave the Arctic producing grounds, for example, when temperatures begin to fall and they need warmer habitats. Similarly, the hottest regions can be a bad environment for raising little chicks, and they will choose cooler areas to lay eggs.
Migrating for Predators (捕食性动物)
Habitats that have rich food resources all the year round also attract a greater number of predators that can threaten their nests. ⑤_____ It gives their young a better chance of reaching maturity. Many birds even migrate to particular habitats that are nearly inaccessible to predators.
A.Birds always tend to fly to warmer places.
B.And changes in those climates can affect migration.
C.This increases the surviving chances of little chicks.
D.Birds have adapted themselves to their own surroundings.
E.There is more than one reason for different birds to migrate.
F.As the food supplies decrease in fall, they return to warm regions.
G.Therefore, birds migrate to different habitats to avoid being eaten by predators.

Scientists say they have developed a system that uses machine learning to predict when and where lightning will strike. Researchers report the system is able to predict lightning strikes up to 30 minutes before they happen within a 30-kilometre radius.
Lightning is a strong burst of electricity in the atmosphere. Since it carries extremely powerful electric charge, it can be destructive and deadly. European researchers have estimated that between 6,000 and 24,000 people are killed by lightning worldwide each year. For this reason, climate scientists have long sought to develop methods of predicting lightning.
The system tested in the experiments used a combination of data from weather stations and machine learning methods. The researchers developed a prediction model that was trained to recognise weather conditions that were likely to cause lightning.
The model was created with the data collected over a 12-year period from 12 Swiss weather stations in cities and mountain areas. The data, related to four main surface conditions: air pressure, air temperature, relative humidity and wind speed, was placed into a unique machine learning algorithm(算法), which compared it to the records of lightning strikes. Researchers say the algorithm was then able to learn the conditions under which lightning would happen.
The researchers tested the system several times. They found that the system made predictions that proved correct almost 80 percent of the time. "It can now be used anywhere," the Swiss Federal Institute of Technology said in a statement.
The researchers plan to keep developing the technology in partnership with a European effort that aims to create a lightning protection programme. The effort is called the European Laser Lightning Rod project. Scientists working on the project are experimenting with the laser technology that could someday control lightning activity, transferring lightning charge from clouds to the ground. They hope that such technology can one day be used as protection against lightning strikes. Possible uses could be at stations, airports or places where crowds of people gather.
1.Why was the system developed
A.To show the power of lightning.
B.To meet kids' curiosity about lightning.
C.To protect people from lightning.
D.To keep track of deaths caused by lightning strikes.
2.What is special about the system
A.It adopted a different machine learning algorithm.
B.It used an effective method of collecting data.
C.It was based on a number of samples worldwide.
D.It required the low cost of predicting lightning.
3.What will the researchers do next with the laser technology
A.Generate electricity with lightning. B.Transfer energy from lightning.
C.Monitor lightning activity. D.Prevent the occurrence of lightning.
4.What can be a suitable title for the text
A.A Theory of Employing Lightning B.A Model of Creating Lightning
C.A System of Controlling Lightning D.A Method of Forecasting Lightning

Imagine an area 34 Limes the size of Manhattan. Now imagine it covered ankle-deep in plastic waste—a total of about 19 billion pounds of garbage. ①______________
"We're being overwhelmed (淹没) by our waste," said Jenna Jambeck, an environmental engineer who led the 2015 study that determined this astonishing number. ②______________, unless something is done to stop the tide of garbage.
Plastic—a widely-used material—has in many ways been a benefit to humans but it has also caused a growing problem. Today, plastics are the No. 1 type of garbage found in the sea. Ocean Conservancy, a nonprofit environmental advocacy group that organises an annual coastal cleanup event worldwide, said plastic waste makes up around 85 percent of the garbage collected from beaches and oceans.
Ocean Conservancy says plastics are believed to threaten (威胁) at least 600 different wildlife species (物种). ③______________; a growing body of evidence suggests humans are consuming plastics through the seafood we eat. Research suggests some plastics could be poisonous to humans, and could potentially increase the risk of health problems.
④______________. At the Economist World Ocean Summit this week, ten nations announced to reduce plastic sea litter as part of UN Environment's Clean Seas campaign. ⑤______________. Corporations also have a role, as do individuals.
We can start by thinking twice before using single-use plastic products—and when we do use them, we should take care to properly throw them off or recycle.
A. The following is what we should do
B. And it’s not just wildlife that's threatened
C. And this figure is likely to double by 2025
D. But it's not just countries that need to do their part
E. By 2050, that figure is expected to rise to 1,000 pieces

Like all big cities, Paris has a traffic problem: lots of cars, lots of traffic jams and lots of pollution from exhaust fumes(废气). So the city began a scheme(计划) to improve the situation.
Under the Velib scheme ("Velib" comes from vélo liberté, or "bicycle freedom"), people can take a bicycle, use it for as long as they want, and then leave it at the same or another bicycle station. The first half-hour on the bike is free, but if you don't return it after 30 minutes, you have to pay. But it's only ? 1 a day or ? 29 a year! The bicycles are heavy (25kg), and they are all grey and have baskets. There are about 20,000 of them in the city, and around 1,450 bicycle stations. So there are a lot more Velib stations than the 298 subway stations!
Paris is not the first city to have a scheme like this. But not everybody thinks it's a great idea. One Parisian said, "These bicycles are only for short journeys. If people want to travel across the city, they won't use a bicycle-they'll still use their cars."
A city spokesman said, "The bicycle scheme won't solve all our traffic problems, of course. But it might help reduce air pollution. Traffic, together with factory fumes, is a big problem. There aren't any simple answers to traffic problems and pollution in cities. But unless we do something now, there will be more traffic jams and temperatures will continue to rise, so the problems of our environment will get worse. The bikes might help people to lead a healthier life, too."
1. What can we learn about the Velib scheme
A. Its bikes have no baskets. B. Its bikes are light and colourful.
C. It aims to make travelling easier. D. It owns more stations than the subway.
2. How much should you pay if you use a Velib for an hour
A. ?1. B. ?30. C. ?29. D. No money.
3. Why do some people disagree with the Velib scheme
A. The cost is rather high. B. It's hard to find a Velib station.
C. It's not suitable for a long journey. D. The distance between two Velib stations is long.
4. What’s the city spokesman's attitude towards the bicycle scheme
A. Doubtful. B. Positive. C. Uncaring. D. Worried.

Cleaning up the existing damage to our environment and preventing further destruction may be a huge job. It can seem like there is no way one person, especially a young person, can make a difference. But you can make a difference, starting with changing some simple everyday habits and working with others to spread the word about the importance of protecting the environment.
Take shorter showers. Yes, everyone wants to look and smell his best, but how many washes do you really need A dripping faucet can waste 3,000 gallons a year, about the same amount you can save by halving your daily shower time. ①___________
②___________ The animals that gave their all to become your hamburger require much more space, energy, and five times more water than the stars of a meatless dish. You don't necessarily have to become vegetarian just for this reason, but eating less meat will probably do your body good while it helps the planet anyway.
Ride your bike or walk instead of driving. ③___________ Yes, every teen looks forward to a driver's license and a first car, but automobiles are one of the primary causes of air pollution. When pedal power won't cut it, take the bus or carpool.
④___________ There are many national organizations devoted to protecting endangered species, cutting greenhouse gas emissions, preserving clean water supplies, and so on. But there are also probably local environmental groups doing things like planting native trees or setting up hard-to-recycle pickups in your own neighborhood.
Don't be afraid to lead. Regardless of what some adults may think, teens can have great ideas too. When you have one, put your youthful energy to good use. Your idea might be as simple as a neighborhood, clean-up day, but go for it. Pass out flyers. ⑤___________ Round up your buddy's garage band and turn it into a block party at the end of the day.

The wildfires damaging parts of Australia can be seen from space in new satellite images released by NASA. Australia's capital, Canberra, was enveloped in a smoky haze Sunday and air quality at midday was measured at 10 times the usual dangerous limit. The damaging fires have killed at least 24 people in Australia and destroyed almost 2,000 homes. The early and damaging start to Australia's summer wildfires, fed by drought and the country's hottest and driest year on record, has also been catastrophic(灾难性的) for the country's wildlife, likely killing nearly 500 million birds, reptiles and mammals in New South Wales alone, Sydney University ecologist Chris Dickman told The Sydney Morning Herald.
Under such extreme conditions, the fires have been generating enough heat to create their own weather systems, including fire-generated thunderstorms and fire tornadoes. Thousands of firefighters continued to fight the flames that have burned millions of acres in New South Wales, Victoria and South Australia, an area twice the size of Maryland. In New South Wales, the Rural Fire Service (RFS) said as of Sunday there were 150 fires active in the state, 64 of them uncontrolled.
On Saturday, Prime Minister Scott Morrison announced that, for the first time in Australian history, 3,000 army, navy and air force reservists (预备役军人) will battle against the fires. He also committed $14 million to hiring fire-fighting aircraft from overseas. On Sunday, cooler temperatures and lighter winds brought some relief to threatened communities, a day after thousands of people were forced to escape as flames reached the suburban areas of Sydney. Thousands of firefighters fought to contain the fires, but many fires continued to burn out of control, threatening to wipe out rural townships and causing almost incalculable damage to property and wildlife.
1. What does the underlined phrase "fed by" in Paragraph 1 mean
A. Be given food by someone. B. Be strengthened by something.
C. Be destroyed by something. D. In the control of something.
2. Why were there thunderstorms and tornadoes
A. The fires generated thunderstorms and tornadoes.
B. There was rainy weather.
C. The fires generated enough heat to create extreme weather.
D. The weather systems are easy to change.
3. What can we learn from the last paragraph
A. Many soldiers will fight against the fires as they have done before.
B. Fires were controlled due to cooler temperatures and lighter winds.
C. A lot of people moved out of the suburban areas.
D. The damage to property and wildlife is limited.
4. What would be the best title for this passage
A. Australia's Destructive Wildfires
B. Soldiers Fought Against the Fires
C. Wildlife Died From the Fires
D. Australia's Wildfires Were Under Control
