As Ginni Bazlinton reached Antarctica，she found herself greeted by a group of little Gentoo penguins(企鹅) longing to say hello．These gentle，lovely gatekeepers welcomed her and kick-started what was to be a trip Ginni would never forget．
Ever since her childhood，Ginni，now 71，has had a deep love for travel．Throughout her career as a professional dancer，she toured in the UK，but always longed to explore further．When she retired from dancing and her sons eventually flew the nest，she decided it was time to take the plunge．
After taking a degree at Chichester University in Related Arts，Ginni began to travel the world，eventually getting work teaching English in Japan and Chile．And it was in Chile she discovered she could get last-minute cheap deals on ships going to Antarctica from the islands off Tierra del Fuego，the southernmost tip of the South American mainland．“I just decided I wanted to go，” she says．“I had no idea about what I'd find there and I wasn't nervous，I just wanted to do it．And I wanted to do it alone as I always prefer it that way．”
In March 2008，Ginni boarded a ship with 48 passengers she'd never met before，to begin the journey towards Antarctica．“From seeing the wildlife to witnessing sunrises，the whole experience was amazing．Antarctica left an impression on me that no other place has，” Ginni says．“I remember the first time I saw a humpback whale；it just rose out of the water like some prehistoric creature and I thought it was smiling at us．You could still hear the operatic sounds it was making underwater．”
The realization that this is a precious land，to be respected by humans，was one of the biggest things that hit home to Ginni．

In a global report of lake color，researchers estimate that roughly one-third of Earth's lakes are blue．But，should average summer air temperatures rise by a few degrees，some of those clear waters could turn a cloudy green or brown，the Learn reports in the Sept．28 Geophysical Research Letters．
The changing colors could change how people use those waters and offer clues about the stability of lake ecosystems．Compared with blue lakes，green or brown lakes have more algae(藻类) and organic matter，says Xiao Yang，a hydrologist(水文专家) at Southern Methodist University．
Lakes in places with average summer air temperatures that were below 19° Celsius were more likely to be blue than lakes with warmer summers．That's because warmer water helps algae bloom more，which changes the properties of the water．
Yang and colleagues used satellite photos from 2013 to 2020 to analyze the color of more than 85，000 lakes around the world．Because storms and seasons can temporarily affect a lake's color，the researchers focused on the most frequent color observed for each lake over the seven-year period．The researchers also created an interactive online map that can be used to explore the colors of these lakes．The approach is “super cool”，the researchers say．These satellite data are “just so powerful”．
If some lakes do become less blue，people will probably lose some of the resources they have come to value，O'Reilly says，who is an ecologist at Illinois State University．Lakes are often used for drinking water，food or recreation．If the water has more algae，it could be unappealing for play or more costly to clean for drinking．But the color changes wouldn't necessarily mean that the lakes are any less healthy．“Humans don't value lots of algae in a lake，but if you're a certain type of fish species，you might be like ‘this is great’．” O'Reilly says．
8．What can we learn about the lakes' color change according to the text
A．It is caused by water pollution．
B．It does harm to the growth of algae．
C．It results from the temperature increase．
D．It can disturb the stability of lake ecosystems．
9．How was the research conducted
A．By doing field investigation．
B．By researching previous studies．
C．By analyzing long-term satellite data．
D．By observing the daily color of the lakes．
10．Which word best describes O'Reilly's attitude to the color change
A．Objective．　　　　　 B．Doubtful．
C．Unconcerned． D．Favourable．
11．What's the author's purpose in writing the text
A．To call on people to protect lakes．
B．To introduce a new research method．
C．To present the outcome of a research．
D．To provide solutions to lakes' color change．
D
Ever since the 1960s，seismologist(地震学家) on multiple continents have detected a mysterious pulse that every 26 seconds．But in the last 60 years no one has been able to figure out what this sound actually is．
The “heartbeat of the Earth” was first recorded in 1962，by John Oliver，a researcher at the Lamont-Doherty Geological Observatory，Columbia University．Then，in 1980，Gary Holcomb a geologist with the U．S．Geological Survey，also discovered the mysterious pulse．But for some reason，the two researchers' discoveries remained virtually unknown for over two decades，until a graduate student at the University of Colorado Boulder once again detected the “heartbeat” and decided to look into it．
Mike Ritzwoller，a seismologist at the University of Colorado，did a lot of work with his colleague，but they were never able to explain what it actually was．
One theory claims that it's caused by waves，while another states that it's due to volcanic activity．The wave theory dates back to 2011，when Garrett Euler，a graduate student at Washington University in St．Louis，tied the origin of the pulse to a part of the Gulf of Guinea called the Bight of Bonny．According to him，when waves hit the continental shelf，the pressure deforms the ocean floor，causing pulses that reflect the wave pattern．Euler's theory was believable，but not everyone was convinced by it．In 2013，Yingjie Xia，a researcher from the Institute of Geodesy and Geophysics in Wuhan，China，suggested that the source of the 26-second pulse was volcanic activity．His theory made sense as well．But neither of the two theories fully explain the pulse．
Why does the 26-second pulse only occur in the Bight of Bonny Waves hit coastlines all over the world，and there are plenty of other regions with seismic activity，so what is so special about this place Well，that's one question that no one has ever answered．And it's not just that it's a tough puzzle to solve，but also that seismologists don't really seem interested in it．
12．What can be inferred about the “heartbeat of the Earth” from the passage
A．Researchers have found out exactly what it is．
B．It was first detected in 1962 by Gary Holcomb．
C．It can only be felt when you are in the Bight of Bonny．
D．It wasn't until the 2000s that it caught people's attention．
13．What is the last paragraph but one mainly about
A．How these two theories came about．
B．An explanation of Euler's wave theory．
C．Two theories about what causes the pulse．
D．Why these two theories are not convincing enough．
14．What is seismologists' attitude towards finding out why the pulse only happens in the Bight of Bonny
A．Indifferent． B．Curious．
C．Anxious． D．Amused．
15．What would be a suitable title for this passage
A．Earth's Heartbeat—A Mysterious Sound
B．Two Theories Related to Earth's Heartbeat
C．Bight of Bonny—Home to Earth's Heartbeat
D．The Reason Why Earth's Heartbeat Happens
第二节
阅读下面的短文，从短文后的选项中选出可以填入空白处的最佳选项，选项中有两项为多余选项。
Left-handed people make up around 12% of the global population．One really interesting fact that I picked up was from a scientist who believed that left-handed people tended to be more independent as a result of having to adapt to a world that is largely built for right-handed individuals． 16 ！
More likely to have allergies and sleep disorders．
A study found that left-handed people were 11 times more likely to suffer from allergies than right-handed folk． 17 ．
Left-handed people use the right side of the brain the most．
18 ，meaning that the right side controls the left side of the body and the other way around．Hence there is a well-known saying “only left-handed people are in their right minds”．The right-hand side of the brain is thought to control the left side of the body and tasks to do with the arts and creativity．
Are left-handed people smarter
19 ！ One 2007 study “Effect of handedness on intelligence level of students”shows that lefties are more likely to have higher IQ．However，another 2010 study “The relationship between hand preference，hand performance，and general cognitive ability” suggests the exact opposite!
20 ．
Experiments showed that when given two tasks to complete simultaneously(同时)，lefties performed best．This is because right-handed people tend to solve problems by breaking them down into parts and analyzing each piece one at a time．While left-handed people tend to look at the problem as a whole and use pattern-matching to try and solve it．
A．Better at multi-tasking
B．Smarter than the right-handed
C．As we know，the brain is cross-wired
D．This one varies depending on how dated your source is
E．Here are a few more fascinating left-handed people facts
F．Mixed-handed children are more likely to experience language issues
G．And lefties were two and a half times more likely to suffer from sleep disorders

I was already afraid of the water．After experiencing a shark attack when I was eight years old on a family trip to Florida，I barely went in the ocean any deeper than my knees．By shark，I mean dolphin，and by attack，I mean he was bobbing around in the water about five miles from shore，but people were screaming “SHARK！”and waving their hands around along the coastline．Real shark or not，that moment stuck with me．That memory，coupled with being freezing in any weather less than thirty degrees Celsius(摄氏)，made the idea of plunging(投入) into cold water a hard pass．
My husband，Mike，had been cold plunging(冰浴) for years and would present me with facts to prove that it was a good thing．By doing so，you experience benefits such as heightened energy，immune(免疫的) system support，boosted mood，better sleep，and stress reduction．It was an appealing list of benefits—none of which mattered to me．What was presented as a clear “wonder drug” was still not attractive enough for me to get out of my warm house and go swimming．Did I mention that I live in Canada It's minus twenty degrees Celsius here sometimes．
On New Year's Day，Mike invited me to his cold plunging．I had been thinking less about health data and more about my confidence．Do you want to do something hard Something brave I asked myself．Something completely scary，uncomfortable and seemingly crazy，or do you want to say no and focus on all of the reasons why you wouldn't dare I put on my swimsuit，covered it up with eighteen wool sweaters，and joined Mike for the adventure．
In fairness，it was a beautiful day．This made the scary thing feel a little more reasonable as I negotiated with myself the entire twelve-minute drive．My heart was already pounding．We had packed a bag with towels，blankets，warm water for cleaning our sandy feet，and a hot cup of coffee to warm our hands．
注意：1．续写词数应为150左右；
2．请按如下格式作答。
I was determined to do the hard thing．
I have now been cold plunging for over a year．

Dear Gaudy，
Knowing that you're interested in Chinese culture，I'm writing to tell you about the lantern riddle guessing competition held by our class．
It was such a meaningful activity that everyone in our class took an active part in it．Firstly，we were randomly divided into eight groups of four students．Then our teacher took out a lantern riddle and saw which group could guess it correctly and quickly．In the end，our group won the first prize．
This activity not only deepened our understanding of traditional culture，but strengthened team cooperation．I hope you can get a chance to be part of it．
Warm regards，

[参考范文]
I was determined to do the hard thing．I dipped a toe in the icy waters．Slowly，I inched my legs forward until the waves unexpectedly climbed up to my kneecaps．My first cold plunging lasted five seconds．I was out of that water faster than a ball from a cannon．I screamed，laughed，and tripped．I had done it! The feeling of accomplishment washed away all my fears．I already knew I had the courage to go under，but now I had to work on staying there．The following week I stayed a little longer．I taught myself I could trust myself，knowing that I was more powerful than that taunting voice in my head．
I have now been cold plunging for over a year． In the depths of winter，I have broken through ice and breathed through the icy cold．I enjoy those moments more than any other part of my day．I am thinking only about survival，not my car payment，the garden that needs cleaning，or my gray hair．The first thirty seconds are still challenging，and l always get a little nervous before I step into the lake or ocean．But I have learned to relax in this state of immersion．What began as a place of fear has become a place of finding happiness．

19．D　[根据本段小标题“Are left-handed people smarter？”可知本段主要围绕着左撇子是不是更聪明来展开，空后2007年的研究与2010年的研究得出了完全相反的结论。因此，关于左撇子是不是更聪明这个问题的答案与消息来源的日期有关，D项“This one varies depending on how dated your source is”既回答了小标题的提问，同时也概括了全段，而且D项中的“This one”指代小标题的问题，符合上下文语境。]
20．A　[根据本段内容可知，左撇子在解决问题时更倾向于整体解决问题。空处为本段标题，所以空处应该讲的是左撇子的另外一个有趣的事实——更善于把问题看作一个整体来解决，A项“Better at multi-tasking”指出左撇子的另一个有趣的事实即善于处理多项任务，符合上下文语境。]

45．personal　[考查形容词。空处应填形容词作定语，修饰名词belongings，故填personal。]
