Scientists say they've developed a new system (系统).It can use"machine learning" to predict when and where lightning (闪电)will strike (闪击).The research was led by engineers from Switzerland.

   European researchers have estimated ( 估算)between 6,000 and 24,000 people are killed by lightning worldwide each year.The strikes can also cause power cuts,destroy houses and start forest fires.For these reasons,some climate scientists have studied to develop methods to predict and control lightning.But no system has been created to effectively predict lightning.

   The new system is being tested in the experiments (实验).It used a combination of data (数据资料)from weather stations and machine learning methods.The researchers developed a prediction model.It was trained to tell weather conditions that were possible to cause lightning.

   The model was created with some data.The data was collected over a 12﹣year period from 12 Swiss weather stations in cities and mountain areas.The data related to(与……有关)four main surface conditions:air pressure,air temperature,relative humidity (相对湿度)and wind speed.

   The atmospheric (大气的)data was put into a machine learning algorithm (计算程序),which compared itto records of lightning strikes.Researchers say the algorithm was then able to learn the conditions under which lightning happens.

   Amirhossein Mostajabi is a PhD student who led the development of the new system.He said,"Common systems for collecting such data are slow and complex,and they require expensive collection equipment (设备)like radar or satellites (卫星)."

   "Our system uses data that can be gotten from any weather station,"Mostajabi said. "This will improve data collection in the areas which are not covered by radar and satellites or in places where communication systems have been cut," he added.

(1)According to the passage,the strikes can't cause       .

A.

power cuts

B.

earthquakes

C.

forest fires

D.

the death of people

(2)What does the underlined word"it" refer to in Paragraph 5?       

A.

The lightning strike.

B.

The system being tested.

C.

The machine learning algorithm.

D.

The atmospheric data.

(3)What do the last two paragraphs mainly tell us?       

A.

Where weather stations should be built.

B.

How the machine learning algorithm works.

C.

The advantages of the new system in data collection.

D.

The new system has effectively predicted lightning in faraway areas.

(4)Which of the following statements about the new system is TRUE?       

A.

Its prediction model has been tested for 12 years.

B.

It has been put into use in cities and mountain areas widely.

C.

The new system requires expensive collection equipment to collect data.

D.

It uses machine learning to predict the time and places of lightning strikes.

How do you get across a river? A bridge is the best way. In some places, there are no bridges. People use the ferry(渡船). A ferry is a boat that takes people and cars across the river.
Both ends of a ferry look the same. The ferry never has to turn around. It docks(靠岸)at one side of the river. People and cars get on. At the other side, the ferry docks again. The people and cars get off. Other cars and people get on. And then the ferry goes back across the river.
In many places, bridges are now taking the place of ferries. In 1964, the longest bridge in the world was built in New York over Now York Bay(湾). It is called the Verrazano-Narrows Bridge. This bridge has two roads, one over the other. Each road is wide enough for six lanes(行道)of traffic.
