It was a sun-kissed spring afternoon along the beautiful Maryland coast, and Jonathan Bauer, a 51-year-old former firefighter, was enjoying a rare moment with his 13-year-old daughter, Ava. The two of them were heading home across the Route 90 bridge, over the waters of Assawoman Bay.
However, the peace of their drive was suddenly disturbed by the noise of tires and a horrible crash just ahead of them. A black truck was out of control, running into a concrete barrier, and finally coming to rest over the bridge’s railing(栏杆).
In that heart-stopping moment, Bauer hit the brakes in time to avoid the vehicles in his path, narrowly avoiding a crash with the truck ahead. But his heart sank as he saw a red car sliding backward towards him. He turned left, but too late——the car ultimately crashed into the trunk of his car.
Bauer stopped the car. “Ava, are you OK?” he asked. Thankfully, Ava emerged from the chaos, but otherwise unhurt. Bauer, however, couldn’t stand by. Rushing to the red car, he checked on its driver. “Are you OK?” he asked the driver. She nodded, too shocked to speak.
Then, suddenly, a scream of “HELP” cut through the air, coming from the overturned truck. As the truck driver climbed out and pointed toward the water, Bauer raced to his side. In the shallow bay waters below, he spotted a car seat and a terrified two-year-old girl, dressed in a pink dress.
Without hesitation, Bauer instructed Ava to call the ambulance as he removed his shoes. He knew the situation was urgent, and he had to act swiftly to save the baby. He climbed onto the bridge’s railing, preparing to make a jump of faith into the water. He was not sure about his chances jumping from this height into such shallow water. And were there rocks this close to the concrete pillar(柱子) of the bridge?

2 . The Joys of College
Often, we college students complain endlessly about all of the things we hate about college. And sure, college is really stressful and there are some aspects I don’t like.
The first thing I truly enjoy about being a college student is that I get to take classes that actually interest me.
The community at the university is also very important to me. We are all suffering here but we are all suffering together.
The university presents us with so many unique opportunities as well. We are encouraged to study abroad, which allows students to experience student life in another country and dive into other cultures in the process.
So although there are a lot of negatives of college—and I mean a lot—there are also a lot of positives. I know that when I graduate, I’m going to miss being a college student.
A.After all, college can be very demanding. |
B.The fun activities and clubs are also a plus. |
C.But for once, I’d like to focus on the positives. |
D.Here, there are so many different fields to study. |
E.Additionally, being a trainee is a great way to get experience. |
F.The college experience can get bearable due to this community. |
G.It isn’t like high school where you’re required to take the same classes. |
3 . Dementia (痴呆), a serious mental disorder caused by brain disease or injury, affects the ability to think, remember and behave normally. 160,000 people have some forms of dementia in Sweden, Alzheimer’s disease being the most common. At the same time, many new diagnostic (诊断的) methods and early-intervention treatment have been developed in recent years, which highlights the need to identify more risk factors for the disease.
Previous studies have demonstrated a possible association between depression and dementia. A present study now clearly shows that people who have been diagnosed with depression are more likely to be diagnosed with Alzheimer’s disease. Unlike the previous ones, the study was conducted using Region Stockholm’s administrative healthcare database, which contains all healthcare contacts recorded by the region. It shows that the risk of Alzheimer’s disease was more than twice as high in patients with stress and in patients with depression as it was in patients without either condition; in patients with both depression it was up to four times as high.
“The reason for it is unknown,” says the study’s last author Axel C. Carlsson. “The finding is important in that it enables us to improve preventative efforts and understand links with the other risk factors for dementia.”
The researchers focused on patients between the ages of 18 and 65 and between 2012 and 2013. They identified 44,447 people with a diagnosis of depression and followed them for eight years to see how many of them were later diagnosed with Alzheimer’s disease. A comparison with all other 1,362,548 individuals in the age group showed that more people with depression had also been diagnosed with Alzheimer’s disease.
“It’s very uncommon for people in this age group to develop dementia, so we need to identify all possible risk factors for the disease,” says Dr Carlsson. “We show here that the diagnosis is more common in people who have suffered depression, but more studies will be required if we’re to demonstrate any reason there.”
1. What do the previous studies and the present one differ in?A.The target. | B.The method. |
C.The purpose. | D.The theory. |
A.It clarifies the condition of dementia. |
B.It makes clear the risks of depression. |
C.It confirms the previous study finding. |
D.It helps with the dementia prevention. |
A.Its process. | B.Its background. |
C.Its application. | D.Its assessment. |
A.Why dementia spreads wide in Sweden. |
B.What links exist among mental diseases. |
C.How depression connects with dementia. |
D.What other risk factors lead to dementia. |
4 . Tropical (热带的) forests could become so hot that some kinds of leaves will no longer be able to conduct photosynthesis (光 合 作用), according to a study. The photosynthetic machinery in tropical trees begins to fail at about 46.7℃ on average. The research suggests that forests may be nearing dangerous temperature sooner than expected. Models predict that once we hit a global temperature increase of 3.9℃, these forests might experience mass leaf damage.
Chris Doughty, an associate professor at Northern Arizona University and the lead researcher of the study, said the leaf-warming experiments had revealed a nonlinear rise in temperatures. “We were really surprised that when we warmed leaves by 2, 3 or 4℃, the highest leaf temperatures actually increased by 8℃. This shows a concerning nonlinear feedback that we were not expecting.” said Doughty. “If we adopt a do-nothing response to climate change and tropical forest air temperatures increase by greater than 4℃, there could be massive leaf death.” he added.
Avoiding high emissions (排放) in the first place is key to stabilizing temperatures. “We should do all we can to avoid high-emissions. Under low-emissions, almost all tropical forest tree leaves can avoid death from overheating and the trees will survive,” said Simon Lewis, a professor of global change science at University College London. “Yet what the study doesn’t look at is heatwaves. We still might see tree deaths from overheating for limited periods during heatwaves under lower emissions.”
Researchers suggest that the damage is not yet unchanged. “Vote for people who are serious about addressing climate change and transferring to low-carbon economies, ”Disney, one researcher, advocated. More generally, we can all recognize the importance of supporting those countries and people who live in and rely on tropical forests economically, But the serious changes to tropical forests don’t just affect the local people it’s a global issue.
1. Which of the following can best replace the underlined word “nonlinear” in Paragraph 2?A.Global. | B.Dramatic. | C.Steady. | D.Minor. |
A.Planting more trees. | B.Exploring heatwaves. |
C.Conducting researches. | D.Pursuing low emissions. |
A.Promoting global efforts. |
B.Seeking economic support. |
C.Helping tropical countries. |
D.Boosting low-carbon education. |
