There are a lot of benefits to staying physically fit. You’ll have more energy, you’ll look great, and you’ll notice improvements in your health. 1. However, if you focus on exercise, you can make a lot of healthy physical changes.
Find the time. Exercise is one of the most important aspects in staying (or becoming) fit and healthy. 2. Try scheduling your exercise the same way that you schedule other appointments and work. You’ll be more likely to stick to it if it’s on the calendar (日历).
3. You will see the most benefits from exercise if you do it regularly. One good way to make you stick to it is to pick a form of exercise that you enjoy. For example, if you like swimming, make it a point to swim twice a week.
Go outdoors. It is really good to work out at a gym—without air conditioning and televisions. But scientists report that exercising outdoors, at least part of the time, can have more benefits. 4.
Be social. If you join other people in your exercise routine, you’ll see a positive influence in your results. 5. If you schedule an activity with a friend, you are less likely to cancel than if you were only cancelling on yourself.
A.Make it a habit.
B.Enjoy your exercise.
C.Unfortunately, it’s not always easy to stay in great shape.
D.In a word, it is absolutely good for you to stay physically fit.
E.Finding a workout partner can help you to stick to your exercise.
F.The road or sidewalk challenges your body in ways that gyms can’t do.
G.Experts recommend that you should be active for at least 30 minutes per day.
Genetic modification (基因改良) dates back to ancient times, when humans influenced genetics by selectively breeding organisms (培育生物) according to an article by Gabriel Rangel, a public health scientist at Harvard University. When repeated over several generations, this process leads to great changes in the organisms.
Dogs were likely the first animals to be purposefully genetically modified, with the beginnings of that effort dating back about 32,000 years, according to Rangel. Wild wolves joined our hunter-gatherer ancestors in East Asia, where the aggressive canines were kept in the household and bred to become docile and easier to get along with. Over thousands of years, people bred dogs with different desired character and physical characteristics, eventually leading to the wide variety of dogs we see today.
The earliest known genetically modified plant is wheat. This valuable crop is thought to have originated in the Middle East and northern Africa in the area known as the Fertile Crescent, according to a 2015 article published in the Journal of Traditional and Complementary Medicine. Ancient farmers selectively bred wheat grasses beginning around 9000 B. C. to create improved varieties with larger grains and hardier seeds. By 800 B.C., the cultivation (培养) of improved wheat had spread across Europe and Asia. The continued selective cultivation of wheat resulted in the thousands of varieties that are grown today.
Corn has also experienced some of greatest genetic changes over the past few thousand years. The main crop was changed from a plant known as teosinte, a wild grass with tiny ears and only a few seeds. Over time, farmers selectively bred the teosinte grasses to create corn with large ears bursting with seeds.
Beyond those crops, many of the fruit and vegetables we eat today, including bananas, apples and tomatoes, have experienced several generations of selective raising, according to Rangel.
In 1973, researchers also modified bacteria to be used as drugs. In 1982, human insulin (胰岛素) made from genetically engineered bacteria, became the first genetically engineered human drugs approved by the FDA.
1.What does the word “docile” in paragraph 2 most probably mean?
A.Gentle. B.Loyal. C.Smart. D.Ambitious.
2.How did the ancient farmers try to improve wheat?
A.Through selective cultivation. B.By editing its genes constantly.
C.Through mixture with teosinte. D.By planting it in large numbers.
3.What can we infer about genetic modification?
A.It is rarely seen in daily life. B.It was quite difficult to accept.
C.It is hardly influenced by humans. D.It played a role in medical field.
4.From which section of a newspaper is the text most probably taken?
A.Health. B.Lifestyle. C.Science. D.Agriculture.
When my 8-month-old cries, I ask him if he’s hungry, or wet or just needs a hug.
“Babububuu,” he says.
What I need is a baby cry translator. That’s just what a team of researchers say they’ve developed.
“Experienced nurses or pediatricians (儿科医师) can identify why baby is crying because they have experience, says Lichuan Liu, a professor of electrical engineering at Northern Illinois University, who conducted the research.” We talked to them, and they mentioned that based on the cry’s’ sound there’re’ some clues (线索).”
So Liu set out to identify the features of cries that can help mark them as expressions of pain or discomfort. These features include differences in pitch (音高) and frequency. The team then developed an algorithm (算法) based on automatic speech recognition to detect and identify these features. This “cry language recognition algorithm” was trained on recordings of baby cries taken from a hospital. It uses compressed sensing, a process that reconstructs a signal based on incomplete data. It can identify a baby cry against a background of, say, adult speech or loud television sounds. By classifying different cry features, like pitch, the algorithm can suggest whether the cry is due to sickness or pain, and identify the degree of urgency.
The team had experienced pediatric care providers assess forty-eight baby cry recordings for probable cause of crying hunger, tiredness, etc. They then compared these to the algorithm’s assessments. The algorithm agreed with the humans 70% of the time. Generally, so-called “uncommon cry signals”—signs of pain or sickness—are high-pitched and very loud compared to ordinary crying.
Liu and her team continue to train the technology for greater accuracy. They also plan to add more features, like the ability to identify and classify movement and facial expressions. This could help give more detailed reading of baby’s emotional (情感的) and physical state. They also hope to begin human trials in the near future.
1.The author mentions the 8-month-old child to ________.
A.draw attention to baby cries B.prove baby cries are common
C.lead in a translator for baby cries D.show the use of cry translators
2.What inspired Lichuan Liu’s idea of doing the study?
A.Pediatric care workers’ words. B.The pediatricians’ strong requests.
C.Her own nursing experiences. D.Her doubts about the previous research.
3.What did the researchers do in the study?
A.They collected baby cries from big hospitals.
B.They got 48 baby cry recordings evaluated.
C.They created an automatic speech recognition.
D.They analyzed cry features with compressed sensing.
4.What can we know about Liu’s cry language recognition algorithm?
A.It has been widely used in daily life.
B.It’s mainly meant for hungry cry signals.
C.It has been proved effective on babies.
D.It’s only been tested on recorded cries now.
