W: Today I’m going to talk about the umbrella. We all know that we put up an umbrella to keep the water off when it rains. But the umbrella was not invented as a protection against rain. It was first used as a shade against the sun. Nobody knows who first invented it. But the umbrella was used in very ancient times. When it first appeared in Egypt, it was used only by the rich as a symbol of their power. In Europe, the Greeks were the first to use the umbrella. During the middle ages, however, the umbrella almost disappeared. Then it appeared again in Italy in the 16th century and later in France and in England. Gradually, most European countries began to use the umbrella. During all this time, umbrellas have not changed much in style, but they do become much lighter.

【题目】 Australia is no stranger to wildfires. The country’s weather patterns create heat and dryness, which fuel occasional bushfires in a natural cycle. However, one that started last September continues to burn, and it may not be natural at all. Scientists say that man-made climate change has played a role in the fire’s creation and duration.

Peter Gleick, a US climate scientist, told Time, “the extent, the severity, and the intensity of these fires wouldn’t have been so bad without the fingerprints of climate change.”

According to Australia’s Bureau of Meteorology, the country’s temperatures have risen by more than one degree Celsius since 1920. The spring of 2019 was Australia’s driest in 120 years. In December, the country saw its hottest day ever, with an average temperature of 41.9.

“Due to enhanced (过度的) evaporation(蒸发)in warmer temperatures, the vegetation and the soils dry out more quickly,” Stefan Rahmstorf, a lead author of the United Nations’ Intergovernmental Panel on Climate Change’s Fourth Assessment Report, told Time.

Worse still, researchers at the UK Bureau of Meteorology believe that wildfires like this might become “normal conditions” in the future, according to the BBC. They looked at 57 research papers published since 2013, which examined the relationship between climate change and the risk of wildfires. They found that the link between the two has already been observed in many parts of the world, including the western US, Canada, southern Europe, and even Scandinavia and Siberia.

“These are impacts we are seeing for one degree of global climate change. The impact will get worse if we don’t do what it takes to make the world’s climate stable,” Corinne Le Quere, a professor from the University of East Anglia in the UK, told the BBC. “What we are seeing in Australia is not the ‘new normal’. It’s a transition(过渡)to worse impacts.”

1What was the wildfire starting last September related to according to scientists

A.Air pollution.B.Human activities.

C.Environment changes.D.Natural cycle.

2What does the underlined phrase in paragraph 2 mean?

A.The meaning of climate changeB.The influence of climate change

C.The control of climate changeD.The possibility of climate change

3What happened with the temperature rising in Australia?

A.Plants stayed as lively as usual.

B.Australia never suffered a hot day.

C.The plants and the soils became dry faster.

D.Every season became the driest in the year.

4What can we infer from the last paragraph?

A.We might see more wildlife.

B.We were to see less disasters.

C.It could be impossible to see wildfires.

D.It would be more difficult to prevent wildfires.

【题目】 X-rays are high energy waves that are invisible. 1For example,doctors can see inside the human body and security guards at airports can see inside your handbag. In 1895,the German scientist,Wilhelm Rontgen,discovered X-rays by accident. He called them X-rays because he hadn't seen such a form of radiation before. 2Wilhelm took the first X-ray picture of the bones of his wife's hand after the discovery. In 1901,he received the first Nobel Prize in Physics for his discovery.

X-rays are valuable in medicine because then can see through certain parts of the body. Doctors can take pictures to see which bones are broken or to find out which teeth have holes. The X-rays are strong enough to pass through the skin and muscles,but they cannot pass through hard objects like bones. In the picture,hard objects like bones are white area3

There are some situations in which X-rays cannot give you a clear picture. Some organs,for example,may prevent X-rays from showing a broken bone. For this reason,computed tomography(CT)was invented. A person is put inside a scanner,which is a large tube-shaped machine. 4 A computer puts together all of these images,which can show doctors more than a normal X-ray can.

5Patients must wear protective clothing for the parts of their body that are not X-rayed. Doc- tors and helpers who work with X-ray machines must wear lead aprons and stand behind screens.

A.Then the person is X-rayed from all sides.

B.Objects that X-rays go through appear dark.

C.In mathematics,X means something unknown.

D.An X-ray machine is used to take these pictures.

E.X-rays,however,can also do harm to your body.

F.However,they can be an essential tool for finding out what's wrong with you.

G.They are useful because they can pass through many things that normal light cannot.

【题目】 Why do you run? Different people have different reasons. Whatever your reason is, there’s one thing we can be sure of: Running is much better injury-free.
