【题目】 PCs are no longer the only things that can be hacked(非法侵入). Anything with an electronic pulse, including cars, TVs and refrigerators, is now a target for hackers. Here are several strangest hacks that show where the future is headed:

Remote-controlling a car – Well-known security researcher Charlie Miller is able to control a car by accessing the automotive computer. In 2011, a security company figured out how to unlock a car and start it just by texting and back in 2010, someone hacked into100 cars in Texas, causing them to honk(鸣响)uncontrollably before he remotely disabled them.

Cyber Murder – In Season 2 of Show Time’s homeland series, hackers kill the US Vice President by hacking his pacemaker(心脏起搏器). Typical Hollywood B. S., right? No. It could actually happen. Well-known security researcher Barnaby Jack, who sadly passed away in July at the age of 35, had been prepared to demonstrate at Back Hat how to hack a pacemaker over Wi-Fi. The attack could kill a person by giving the pacemaker a high-voltage shock.

Spy Phone – By now, more people are becoming aware of the potential for a phone to be hacked. But what many fail to realize is the awesome potential of a smart phone to affect you, it has been hacked.

When Your TV Watches You – This type of hack makes it possible to monitor people in their homes via the internet. Smart TVs aren’t that common yet, but in the next few years they could become an important part of the living room, so watch out.

【题目】 The victims were carried in one by one, their paws burned and fur burnt, suffering from dehydration (脱水) and fear. Their caretakers bandaged (用绷带包扎) their wounds and laid them in baskets with the only thing that was familiar — the leaves of a eucalyptus (桉树) tree. As fires have burned more than two million acres in Australia, dozens of koalas have been rescued from burned trees and pale ground. The animals are being treated in rescue centers, and at least one private home, along the country’s east coast.

The difficult situation of the koala — a national symbol of Australia — has raised questions among environmentalists and scientists about what it will take to protect biodiversity (生物多样性) in a country with intense fire, extreme heat and lack of water. Australia has already been among the highest rates of species extinction in the world.

The bad situation goes beyond koalas. Recently, tens of thousands of bats fell from the sky in temperatures over 107 degrees Fahrenheit in northern Australia. Kangaroos destroyed the grapes in Canberra because of drought.

“Climate change and other human impacts have so changed the situation that the government needs to rethink its way to protect at once,” Dr. Bowman said, suggesting interventions (干预) like irrigating, feeding and moving animals to new places.

Koalas, unlike kangaroos, birds or snakes, do not escape from fires. Therefore, though the fires are still burning, a rescue team began to search the area carefully. Walking in a human chain, they looked up to the tree top, searching for survivors.

1What do the victims in the first paragraph refer to?

A.Animals injured in fires.

B.Kangaroos driven by drought.

C.Bats that fell from the sky.

D.Koalas rescued from the fire.

2Which of the following may cause the extinction of wildlife?

A.Wildfires that seldom happened.

B.Extreme hot weather in Australia.

C.The never-changing climate in Australia.

D.Not having enough money to take measures in Australia.

3What can we draw from Dr. Bowman?

A.Human activities have little influence on animals.

B.The government should take immediate action.

C.The government does not care about the wild animals.

D.Scientists are concerned about the bad situation of wildlife.

4What’s the best title for the text?

A.Saving the Fire Victims Who Cannot Escape: Australia’s Koalas

B.Saving the Endangered Wild Animals in Australia

C.Actions Needed to Protect Habitat for Koalas

D.National Symbol of Australia Needs Rescue

【题目】 At the World Economic Forum last month, President Trump drew claps when he announced the United States would respond to the forum's proposal to plant one trillion(万亿) trees to fight climate change. The trillion-tree idea won wide attention last summer after a study published in the journal Science concluded that planting so many trees was “the most effective climate change solution to date”.

If only it were true. But it isn't. Planting trees would slow down the planet's warming, but the only thing that will save us and future generations from paying a huge price in dollars, lives and damage to nature is rapid and considerable reductions in carbon release from fossil fuels, to net zero by 2050.

Focusing on trees as the big solution to climate change is a dangerous diversion(偏离). Worse still, it takes attention away from those responsible for the carbon release that are pushing us toward disaster. For example, in the Netherlands, you can pay Shell an additional 1 euro cent for each liter of regular gasoline you put in your tank, to plant trees to balance the carbon release from your driving. That's clearly no more than disaster slightly delayed. The only way to stop this planet from overheating is through political, economic, technological and social solutions that end the use of fossil fuels.

There is no way that planting trees, even across a global area the size of the United States, can absorb the huge amounts of fossil carbon released from industrial societies. Trees do take up carbon from the atmosphere as they grow. But this uptake merely replaces carbon lost when forests were cleared in the first place, usually long ago. Regrowing forests where they once grew can undo some damage done in the past, but even a trillion trees can't store enough carbon to head off dramatic climate changes this century.

In a sharp counter argument to last summer's Paper in Science, Justin Gillis wrote in the same journal in October that the study's findings were inconsistent with the dynamics of the global carbon cycle. He warned that “the claim that global tree restoration(复原) is our most effective climate solution is simply scientifically incorrect and dangerously misleading”.

1What do we know about the trillion-tree idea?

A.It was published in a journal.

B.It was proposed last summer.

C.It was put forward by Trump.

D.It drew lots of public attention.

2What is paragraph 3 mainly about?

A.A drawback of the tree planting strategy.

B.An example of balancing carbon release.

C.An anecdote of making a purchase at Shell.

D.A responsibility for politicians and economists.

3What was Justin Gillis's attitude towards global tree restoration?

A.Indifferent.B.Opposed.

C.Hesitant.D.Supportive.

4What is the best title for the text?

A.Contradictory Ideas on Tree Planting.

B.A Trillion Trees Come to the Rescue.

C.Planting Trees Won't Save the World.

D.The Best Solution to Climate Change.

【题目】阅读下面短文,在空白处填入1个适当的单词或括号内单词的正确形式。

Many parents are alert to their kids use of electronic devices and set strict limits for them. They want to protect their children from the potentially 1 (harm) effects of too much screen time. But there’s another device-related danger that parents may be overlooking-and 2 might hurt their kids just as much as traditional screen time.

It's been dubbed “secondhand screen time”. With secondhand screen time, kids are3 (direct) exposed to screens being used by someone else close to them. “Generally, we are talking about children who 4 (care) for by adults spending excessive time on devices and the negative consequences that can occur 5 they experience screens being such a dominant part of the adult’s life,” says Nicole Beurkens, PhD, the brand ambassador to Oustodio, a parental control app designed 6 (manage) kids online activity.

Secondhand screen time can also lead 7behavior related problems. Research shows that children have a 8 (tend) to exhibit more acting out behaviors when parents spend excessive time on their devices.

【题目】 “Outer space is a frontier that inspires us and unites us more than anything else,” declared the US Assistant Secretary for Arms Control, Dr. Yleem Poblete. “And as we continue to push further into our own solar system, new businesses will be built to seize the endless possibilities before us.”

However, there are growing concerns about the possibility of intentional acts of aggression in space, warned Dr. Poblete. The United States has raised concerns for many years that Russia is seeking the development and placement of anti-satellite weapons. As recently as February 2017, a Russian Air Force Squadron Commander stated that Russia is developing new missiles with the intention of destroying satellites. Furthermore, we have read statements from the Russian Ministry of Defense that it is working on creating “a mobile attack anti-satellite system”.

Vladimir Putin (Russian President) has alluded to space weapons being more “acceptable in the political and military respect”. This behavior continues despite Russia stating many times that it places a high priority on the promotion of the draft “Treaty on the Prevention of the Placement of Weapons in Outer Space” or PPWT.

The problem with such a treaty, said Dr. Poblete, is that it's difficult to determine an object’s true purpose simply by observing it on orbit. At this time, there are no means of distinguishing many objects' behaviors from that of a weapon, making outer space arms control measures like those in the proposed PPWT impractical.

In short, said Poblete, the proposed PPWT does not reduce the potential for conflict from extending into outer space. Plus, Russia may be engaging in the very behavior it claims to seek to prohibit.

“We must take concrete steps to strengthen the stability and sustainability of space,” declared Dr. Poblete, “The draft PPWT is not the right approach to accomplishing that. It is a questionable document, proposed by a country [Russia] that has routinely violated its international commitments.”

1What does America suspect Russia is doing?

A.Launching satellites for spying.B.Trading space weapons illegally.

C.Making profits from exploring space.D.Causing threat to space stability.

2Which is one common difficulty for controlling space weapons?

A.They are hard to be identified.B.They are not regulated by common rules.

C.There are too many to be managed.D.There is disagreement between nations.

3What does Dr. Poblete think of PPWT?

A.It is not specific enough.B.It will worsen international relationships.

C.Russia itself fails to observe it.D.We must work together to promote it.

4What is mainly discussed in the passage?

A.Where the key to space safety lies.B.What alarms the US as to space safety.

C.Why space conflicts are difficult to avoid.D.Who is to blame for the chaos in outer space.

【题目】 Even in the best and most loving of times, families can feel impossibly confined (受限制的). Teens are irritable and furious. Parents are annoying and embarrassing. For Esther and her daughter Chaya, the tiny new coronavirus changed all that.

Esther was born in Wuhan-a dynamic and culturally rich place that she deeply loves but moved to the U.S. During the winter holiday, they went to Wuhan to visit Esther’s parents. Gradually at first, then more frequently, they noticed face masks on city streets. To be safe, they wore their own masks and stopped going to public gatherings. Then, suddenly the city was on lockdown. No one could leave. Their reservations home on a China Southern airlines flight were worthless. “I feared for my daughter’s life,” said Esther, “If it got worse, there could be chaos. She doesn’t speak much Chinese.”

For days, Esther repeatedly called and emailed for help. It was nonstop. She stayed online, checking all the time. Chaya felt distressed and helpless. It's awful seeing her mother go through that-without having anything she could do to help in the hotel.

Their luck changed with one email. For the 1,000 Americans stuck in Wuhan, there were 230 available seats on one outbound flight, it said. Esther bought two $1,100 seats. After a 12-hour wait at the airport, they got clearance to leave, and arrived at March Air Force Base, where they were isolated in two small connected rooms with a shared bath for two weeks. There were daily medical checkups, twice daily temperature checks and a 10 a m. briefing (简报). But there was no WiFi, TV or friends. For emotional support, Esther phoned her husband Haim, an engineering manager for Uber, and their two other children, ages 13 and 11.

Now home, they are basking in (沉浸于) the thrill of phone calls, TV interviews and a caring community. They’ve gotten little sleep. Suitcases remain unpacked. But anyhow, they have survived not just the outbreak of a virus but the unforgettable experience of mother-daughter togetherness.

1What can be inferred from the second paragraph?

A.The culture and vitality of Wuhan have attracted Esther and Chaya there.

B.The virus has affected people's life in Wuhan.

C.The flight of going back to the U.S. has been postponed.

D.The city was locked down because it was in chaos.

2What caused Chaya's depressed mood?

A.Seeing her mother suffer from reaching out for help.B.Being kept in Wuhan for poor health.

C.Missing her family and friends at home.D.Being unable to speak Chinese.

3Why were they isolated after Esther and Chaya arrived at the airport?

A.The concern of their safety as well as the public’s.

B.Their infection of the virus.

C.The lack of flight home.

D.Their emotional problems after the experience.

4What is the best title of the text?

A.Life in Wuhan: fighting the virus together.

B.Life about people infected by the virus.

C.Life about a mom and teen united by a virus.

D.Life about a mom and daughter from the U.S.
