21、In my thirty years as a time management speaker, I have observed (观察) a lot of what we can not and should not do to increase our daily results. Time management is not necessarily working harder, but rather smarter.
A lot of our time management has to do more with what we are not doing rather than what we are doing. Sometimes our mistakes will keep us from running at a full pace. Here are some time management mistakes we should all avoid to help us increase our daily efficiency:
Start your day without a plan of action. Without a plan, you will have worked hard but may not have done enough right things. Time management is not doing the wrong things more rapidly. That just gets us nowhere faster. Time management is doing the right things.
Work with a messy (凌乱不堪) desk or work area. Studies have shown that the person who works with a messy desk spends, on average, one and a half hours per day in looking for things. That’s seven and a half hours per week. If you have ever visited the office of a top manager, you can easily find that he or she is working with a clean desk environment.
Don’t take a lunch break. Many people do not take a lunch break. They work through that time period in the hope that it will give them more time to finish the task. Studies have shown that it may work just the opposite. After doing what we do for several hours, our mind will become boring. A lunch break, even a fifteen-minute break, gives us a chance to get our batteries all charged up again.
【1】With a plan of action, you can ______.
A. work harder
B. do the wrong things more rapidly
C. avoid doing wrong things
D. get nowhere faster
【2】Working with a messy desk or work area, you will ______.
A. waste a lot of time
B. find the things you need easily
C. become a top manager
D. save seven and a half hours per week
【3】The text mainly tells us ______.
A. how to avoid wasting time
B. we should get our batteries all charged up
C. how important time management is
D. some time management mistakes
22、In the 19th century, doctors tried to transfuse blood (输血)to patients who had lost blood in accidents or to try to save them. However, in most cases there would be a horrible reaction. When the donated blood mixed with the patient's own blood，it clotted (凝结)almost immediately. That stopped the circulation (循环)and the patient would die. Born on 14th June 1868，Karl Landsteiner，a doctor in Vienna, was very concerned about this. He knew there was something in the blood that caused reactions, but some people did manage to escape. Perhaps different people had different kinds of blood? He got a lot of blood samples (标本)from people, and mixed and matched them. Blood has two parts，the blood cells and the liquid serum(血清).You take blood cells from one person and mix them with the serum of another. If they react, the cells will clot and form a big lump. That means it is not safe to transfuse blood between these people. Landsteiner matched hundreds of samples like this，to find out who was safe for whom and who wasn’t. In fact, there were blood groups now called A, B, AB and O.
So what was going on in the blood? All our red blood cells have sugar molecules(糖分子) that are stuck on their surfaces. The red blood cells of people with group A have one kind of sugar, while those with B have another. People with AB have both of these while people with O have none.
People with the A blood group have a chemical substance called anti-B, while those of B blood group have anti-A in their serum. People with AB group have neither anti-A nor anti-B, while people with O have both. If you were B group and got blood from an A person,the anti- A in your blood would cause all the cells with A-sugar on them to clot immediately, stopping the circulation of blood.
In 1907, Dr. Reuben Outenberg carried out the first safe blood transfusion by matching blood groups. Blood transfusion became quite common from then on. And it helped saved thousands of lives in the First World War.

23、The South Pole has been warming at more than three times the global average over the past 30 years, according to research led by Ohio University professor Ryan Fogt, and Kyle Clem, who is a current postdoctoral research fellow in climate science. According to the study, this warming period was mainly driven by natural tropical (热带的) climate variability and was likely strengthened by increases in greenhouse gases.
Clem and his team analyzed weather station data at the South Pole, as well as climate models to examine the warming in the Antarctic interior (内陆). They found that between 1989 and 2018, the South Pole had warmed by about 1. 8℃ over the past 30 years at a rate of +0. 6℃ per decade—three times the global average.
The study also found that the strong warming over the Antarctic interior in the last 30 years was mainly driven by the tropics, especially warm ocean temperatures in the western tropical Pacific Ocean that changed the winds in the South Atlantic near Antarctica and increased the delivery of warm air to the South Pole. They suggest these atmospheric changes along Antarctica's coast are an important mechanism driving climate anomalies (异常事物) in its interior.
Clem and Fogt argue that these warming trends were unlikely the result of natural climate change alone, stressing the effects of added warming related to human activities on top of the large tropical climate signal on Antarctic climate have worked together to make this one of the strongest warming trends worldwide.
“From the very beginning, Kyle and I worked very well together and were able to accomplish more as a team than we were individually,” Fogt said. “We have published every year together since 2013, with one of our continuing collaborations being the annual State of the Climate reports. Our work on this project together each year ultimately led to this publication documenting the warming at the South Pole. However, most importantly for my family and me, apart from being a fantastic scientist and collaborator, Kyle is also considered as one of our closest friends.”
【1】What is the major cause of the South Pole's warming according to the research?
A．The weather station.
B．Lack of winds.
C．Increases of greenhouse gases.
D．Natural tropical climate change.
【2】What is paragraph 3 mainly about?
A．The tropical climate signals in the Antarctic interior.
B．The effect of human activities on the warming trends.
C．The detailed explanation for the South Pole's warming.
D．The unpleasant consequences of natural climate change.
【3】Which of the following does Fogt most probably agree on?
A．Cooperation is valued in scientific research.
B．Getting science paper published is difficult.
C．Friendship is more important than science.
D．Family support plays a key role in science.
【4】From which is the text most probably taken?
A．A chemistry textbook.
B．A science magazine.
C．A travel brochure.
D．A science novel.
24、Just as our bodies produce waste every day — which is why we need to shower and use the toilet —our brains produce harmful waste proteins. But how can our brains “shower” themselves?
A 2013 study found the answer. Researchers at the US University of Rochester studied the brains of mice and discovered that they cleaned themselves while the mice slept. A kind of fluid in the brain, called cerebral spinal fluid (CSF脑髓液), was found to increase dramatically during sleep, washing away waste proteins that had been building up between braincells in waking hours.
“This study shows that the brain has different functional states when asleep and when awake,” Maiken Nedergaard, the lead researcher, told NBC News. It also explains why we can’t think clearly after a sleepless night while a good night’s sleep leaves us feeling sharp and refreshed.
Now a new study, published on October 31 in Science, digs a little deeper into our brains’ self-cleaning procedure. Instead of mice, this time humans were the test subjects.
Researchers at Boston University, US, monitored the brain waves of 13 healthy adults who were sleeping, using accelerated FMRI, which is capable of recording faster changes inside the brain than a regular FMRI machine. They found that every 20 seconds, blood flowed out of the brain, making room for a large amount of CSF to come in and “clean”. This cycle coincided (巧合) with the rhythm of the brains slow waves — an electrical activity that happens when we’ re in deep sleep.
It’s still unknown how these brain activities are connected. But the mere fact that they are connected is exciting enough, since it allows researchers to piece together possible new explanations for misunderstood diseases.
For example, slow-wave sleep has been proven to play a role in strengthening our memories. This may explain why people with Alzheimer’s often have fewer and weaker slow brainwaves. Based on this new study, there could be one more explanation for diseased brains: They are not clean.
Nedergaard, leader of the 2013 study, is also excited about the new findings. “Maybe the most important take-home message is that sleep is a serious thing,” she told Scientific American. “You really need to sleep to keep a healthy brain because it links electrical activity to a practical housekeeping ‘function’.”
