1 . The newly-elected president of Brazil, Jair Bolsonaro says that his country should withdraw (退出) from the 2015 Paris Agreement, and that Brazil’s rainforest protections are standing in the way of economic success. During the election campaign, he promised to ease protections for areas of the Brazilian Amazon set aside for native people and wildlife. Are Brazil’s rainforests in danger?

The Amazon, the world’s largest rainforest, is called “the lungs of the planet.” Each tree takes in and stores carbon dioxide from the air around it. Billions of trees pull up water through their roots and release water vapor into the air, forming tiny drops of water. The Amazon creates 30 to 50 percent of its own rainfall. Carlos Nobre, a climate scientist, says that it is almost impossible to say Just how important the rainforest is to the planet’s living systems.

Some of Bolsonaro’s support comes from business and farming groups. One supporter, Luiz Carlos, noted that farmers “are not invaders, they are producers.” He blamed the past government for supporting rainforest protections at the cost of farmers. “Brazil,” he said, “will be the biggest farming nation on Earth during Bolsonaro’s years.”

Paulo Artaxo, a professor of environmental physics at the University of Sao Paulo, says that if Bolsonaro keeps his campaign promises, then “deforestation of the Amazon will probably increase quickly — and the effects will be felt everywhere on the planet.”

Other scientists warn that if the Amazon and other tropical rainforests lose too many trees, this could affect rainfall in other areas. Without enough trees to support the rainfall, the longer and bigger dry season could turn more than half of the rainforest into a tropical grassland.

3 . Summer is a great time to hit the beach, but a few East Coast beach goers have recently had their fun in the sun turned into a nightmare. In July alone, there have been at least five known shark attacks at Carolina beaches. Although shark attacks are actually quite rare, these animals still inspire fear in ocean waters.     1    

Skip feeding time.

    2     Of course, an attack can happen at any hour of the day or night, but night-time and its transitions are statistically the worst times to be in the water. It is believed that the lack of visibility during these hours makes it easier for the sharks to mistake you for one of their typical prey animals.

    3    

You don't need to dump shark repellent（驱鲨剂）into the sea when you swim, but it helps to be less attractive as a target. Since sharks tend to attack individuals, swim or surf in groups. Don't wear brightly colored or high-contrast swimwear that is attractive to sharks, and leave the shiny jewelry at home in case of being mistaken for the scales（鳞片）of a fish.     4     Playfully splashing（泼打戏水）around resembles sharks' prey in trap.

Fight back.

When a shark wants to eat you, you'll know in advance: It will hunch its back, lower its fins, and rush at you in a zigzag pattern. Use your dive knife or anything else you' re packing to discourage it.     5     If you are completely unarmed, punch the shark's super sensitive nose or stab at its eyes or gills. If the shark bites into you, don't give up. Get aggressive and do some damage to the shark. It might just let go.

A．Don't act like dinner.

B．Don't go into the water individually.

C．Also watch your movement in the water.

D．Nevertheless, the following three aspects could help.

E．If you have a surfboard or bodyboard, use it as a shield.

F．If you actually get trapped, avoid irregular movements and splashing.

G．The time of a day has always been a factor in a possible shark attack on humans.

6 . If you shoo (发噓声把……赶走) a pigeon, that bird is likely to remember you and know to stay out of your way the next time you cross paths, according to a new study. Researchers found that wild, untrained pigeons can recognize individual people’s faces and are not fooled by a change of clothes.

In a park in Paris, two researchers of similar build and skin colour, but wearing different-coloured lab coats, fed a group of pigeons. One researcher ignored the pigeons after feeding them, allowing them to eat the food, while the other was hostile and chased them away. This was followed by the second session when neither researcher chased away the pigeons. The experiment was repeated several times, with the pigeons continuously recognizing the individuals and avoiding the researcher who had first chased them away even when the participant no longer did so. Exchanging lab coats during the experiments did not confuse the pigeons, and they continued to stay away from the researcher who had been initially hostile.

“It is very likely that the pigeons recognized the researchers by their faces, since the individuals were both female and of a similar age, build and skin colour,” study researcher Dalila Bovet said in a statement. “Interestingly, the pigeons, without training, spontaneously (自发地) used the most relevant characteristics of the individuals (probably facial traits) instead of the lab coats that covered 90 percent of the body,” Bovet added.

The researchers noted that the birds appeared to be able to distinguish between humans and be aware that clothing colour was not a good way to tell humans apart. They theorized that this recognition ability might have come about over the long period of association with humans, from early domestication (驯养) to many years of living in cities.

1. What does the underlined word in the second paragraph mean?

A．Aggressive.

B．Unfamiliar.

C．Demanding.

D．Friendly.

2. What feature is the pigeons’ recognition probably based on?

A．The researcher’s build and skin colour.	B．The researcher’s smell.
C．The researcher’s sex.	D．The researcher’s face.

3. What makes the pigeons distinguish between humans properly?

A．The training of the researchers.	B．Early domestication in the countryside.
C．The long time of dealing with humans.	D．Many years of living in the wild.

4. Where can we most probably read this text?

A．In a travel handbook.	B．In a history book.
C．In a science report.	D．In an economic journal.
