Climate change is bad news for the world’s coral reefs. As global temperatures increase, the world’s glaciers melt, 1 cause sea levels and ocean temperatures to rise. These conditions have led to coral bleaching(白化) events, 2 the coral turns white and slowly dies, unable to survive in its changing environment.

Global sea levels 3expect to rise about 1.5 feet by 2100, meaning coral reefs will be deeper underwater than they were 4previousin. The deeper the coral, the less light it receives, and the less 5able it has to make food. This has potential to change the entire ecosystems of reefs and the marine life they support.

But a new study from a team of 6researcher at the National University of Singapore NUS provides a ray of hope. They studied nearly 3,000 corals from 124 species at two reefs off 7 coast of Singapore: Pulau Hantu and Raffles Lighthouse. The water where these reefs live is 8cloud, murky and thick with sediment(沉淀物).

The light reaches down about 26 feet, yet there are corals growing well 9 that level and below. They’ve adapted to surviving under the changing conditions. Researchers say it’s likely that these corals will survive sea-level rise, according to the findings 10publish in the journal Marine Environmental Research.

【解析】

这是一篇说明文。由于全球变暖,海平面上升,导致珊瑚白化事件,但新加坡国立大学(NUS)的一个研究小组的一项新研究表明在新加坡海岸外的两个珊瑚礁的珊瑚在光照大约26英尺深的地方生长的很好。

1

考查非谓语动词。句意:随着全球气温升高,全球冰川融化,造成海平面和海洋温度上升。此句中已有一个谓语动词melt,故cause在这里作状语,又因与the world’s glaciers为主动关系,所以用现在分词作结果状语,故填causing

2

考查定语从句。句意:这些情况导致了珊瑚白化(白化)事件,珊瑚变白并慢慢死亡,无法在不断变化的环境中生存。coral bleaching(白化) events是先行词,关系词在定语从句中作地点状语,所以用关系副词where。故填where

3

考查时态和语态。句意:预计到2100年,全球海平面将上升约1.5英尺。此句sea levelsexpect 之间为被动关系,并且在句子中作谓语,故用be+动词过去分词,又因此处表客观情况,名词levels为复数,故填are expected

4

考查副词。句意:这意味着珊瑚礁的水下深度将比以前更深。此处缺少一个副词修饰,所以将形容词转化为副词,故填previously

5

考查名词。句意:珊瑚越深,接受的光就越少,它制造食物的能力也就越低。此处less为形容词,后需要接名词,所以将形容词able转化为名词。故填ability

6

考查名词。句意:新加坡国立大学(NUS)的一个研究小组的一项新研究提供了一线希望。a+team+of+名词复数形式,此处表示“由研究员们组成的研究小组”,故填researchers

7

考查冠词。句意:他们在新加坡海岸外的两个珊瑚礁(汉图岛和莱佛士灯塔)研究了124种近3000种珊瑚。coast为可数名词,此句表示特指“新加坡的海岸”,故填the

8

考查形容词。句意:这些珊瑚礁生活的水域浑浊。空格前为is,后应该接形容词来修饰名词the water,故填cloudy

9

考查介词。光照到大约26英尺深的地方,但在那一层及以下的地方仍有珊瑚生长良好。at that level是固定搭配,故填at

10

考查非谓语动词。句意:研究人员说,根据发表在《海洋环境研究》杂志上的研究结果,这些珊瑚很可能会在海平面上升后幸存下来。此句say后面为宾语从句,在从距离,survive为谓语动词,所以publish不能做谓语动词成分,又因与findings为被动,故填published

【题目】 A decade ago, colored lights danced around the living room on New Year’s Eve and happy music was played. Upstairs, the children were asleep. But I wasn’t feeling happy. In mid-December, my husband and I had been informed that he had cancer and that he was going to die. He had less than a year left, the doctors said.

In the years since that painful season, I have come to look back upon New Year’s Eve. New Year’s Eve brings a halt to the endless commitments that fill our daily lives and a chance to reflect. New Year’s Eve is full of possibility and anticipation. What will be the surprising experiences and delightful successes in the coming year? But also, what disappointments are waiting for us in the next twelve months?

In many ways, New Year’s Eve and the days that surround it are a line between past and future. That line is made up of a series of moments of transition (过渡) that take us out of the old and into the new. Transition can be challenging for many of us. It’s about letting go of the familiar and diving headlong (迅猛地) into the unfamiliar.

Just as, back then, I had to face letting go of the life I had led with my beloved husband and stepping into a new world as a widowed mom, I find that each year I have to step out of the version of me that suited the year that is ending and ease into the version of me who will rise to the goals I am holding for myself for the year ahead.

Last year at this time, I sat in a chair in southern France and drank in the stillness (沉静) and beauty of the countryside around me. The three children I had brought into this world talked and laughed around the table beside me as we enjoyed a lunch of bread and cheese.

I was filled with a sense of joy and I had a glowing (热情洋溢的) heart that was full of hope. It was another ending and another beginning. May we all transition into the best of what lies ahead. May we all find happiness in this holiday season.

【题目】 Many mental health professionals viewed the pursuit of happiness as a foolish mistake until quite recently. Most of them used to concentrate their energy and attention on individuals suffering from diseases like depression and anxiety, or on relieving despair rather than promoting well-being. But that’s all beginning to change. Supporters of “positive psychology” think that happiness is a goal that people can—and should—work toward. They believe that it’s not only possible but crucially important. Health means not just the absence of disease but a positive sense of involvement and engagement in life. Unless you know how to enjoy life, your life is not really happy. This doesn’t mean that finding happiness is easy—a variety of obstacles stands in the way. The first, perhaps the biggest, is genetics.

Happiness, it seems, is decided—at least in part—by personality features that are largely passed on from their parents. In a study published in 2018, researchers at the University of Edinburgh examined personality and happiness data on more than 900 pairs of twins. They found a close genetic relationship between happiness and positive personalities such as openness and agreeableness. Identical twins (同卵双胞胎) were more likely to share these positive features than non-identical twins; they were also more likely to report similar levels of well-being.

Major life events as well as social and economic factors can also stand in the way of happiness. More often than not, however, people get in their own way by looking for happiness in all the wrong places. They aren’t particularly good at recognizing what will bring them lasting joy: Although money tops many people’s wish lists, study after study has found that once basic needs are met, additional wealth doesn’t add much to people’s sense of well-being and contentment.

Experts in the field of positive psychology still believe it’s possible for people to push their happiness upward—not just temporarily but over the long term.

1What’s the shift in mental health study?

A.Health means the absence of disease.

B.Emphasis is placed on the pursuit of happiness.

C.Well-being is found to be something one was born with.

D.More attention is paid to anxiety and depression.

2Which of the following statements is NOT true?

A.Different obstacles are in the way of finding happiness.

B.Happiness is largely dictated by one’s personality.

C.Identical twins are more likely to be on the same level of well-being than non-identical twins.

D.Wealth always plays an important role in people’s sense of happiness and contentment.

3The obstacles standing in the way of happiness include all of the following elements EXCEPT .

A.emotive factorsB.genetics

C.social factorsD.economic factors

4According to the experts of positive psychology, what’s the essential point of the pursuit of happiness?

A.Material prosperity.B.Freedom.

C.Long-term efforts.D.The avoidance of stress.

【题目】阅读下面短文,根据其内容写一篇60词左右的内容概要。

Are you sick of going to bed late and waking up tired? Then grab your hiking boots and a tent. A new study suggests that a couple days of camping in the great outdoors can reset your circadian (昼夜节律的)clock and help you get more sleep.

The circadian clock, more commonly known as the body clock, is an internal system that tells our bodies when it's time to go to sleep and when it's time to wake up. Scientists track this clock by measuring the amount of melatonin(褪黑激素)circulating in a person’s blood at any given time. In a healthy sleeper, melatonin levels rise a few hours before bedtime, stay high through the night, and then settle back down when it's time to wake up.

In our modern society, however, most of us stay up many hours past sunset and would probably sleep in many hours after sunrise if we could. And the trouble is that your melatonin levels may still be high when your alarm clock goes off in the morning, which leads to grogginess(头晕眼花). It may also have other health consequences as well, such as diabetes(糖尿病), overweight problems and heart disease

Professor Kenneth P. Wright of the University of Colorado in the US wanted to see if our body clocks can be reset by a short stay in nature. His team recruited (招收)14 physically active volunteers in their 20s and 30s. Nine went on a weekend camping trip, while the other five stayed home. At the end of the weekend, the researchers reported that in just two days, the campers' body clocks had shifted so that their melatonin levels began to rise more than an hour earlier than they did before they left on the trip. By contrast, the body clocks of the group that stayed home shifted even later over the course of the weekend. 'This tells us we can reset our clocks fast, ' Wright said.

Therefore, if you want to change your sleep patterns you could try to increase your exposure to natural light during the day and decrease the amount of artificial light you see at night.
