My grandfather, a retired teacher, is in his early eighty. Though problems came along with age, he never gives up learning. That he enjoys most in his spare time is picking up a book to read it, with glasses on. Wherever he meets new words, he will look them up in a dictionary. His thirsty for knowledge has great influenced me and my brother. As a result, we have made up our minds study hard and both of us agreed with the dream of being teachers in the future. Now we’re looking forward to making it realize.
5 . With the ocean covering more than 70% of the Earth’s surface, the National Oceanic and Atmospheric Administration (NOAA) said scientists and researchers had depended on sonar (声呐) technologies to understand and map the sea floor which had charted only about 10% of the world’s ocean. For the ocean and coastal waters in the US, the number is just around 35%.
We know less about our planet’s ocean than what we know about the far side of the moon or the surface of Mars. Part of the reason for the lack of observation is the challenge of powering an underwater camera. Researchers have used ships to recharge cameras or observed with a camera tied to a ship to solve the issue, which is expensive and unsuitable for long-term observations.
Recently, researchers at the Massachusetts Institute of Technology (MIT) have taken a major step to iron out this problem by developing a battery-free, wireless underwater camera that could harvest energy underwater on its own for long periods.
To keep power consumption as low as possible, the researchers used off-the-shelf, ultra-low-power imaging sensors. The device takes color photos, even in dark underwater environments, and sends image data wirelessly through the water.
The camera is powered by sound. It changes mechanical energy from sound waves traveling through water into electrical energy that powers its imaging and communications equipment. After getting and encoding image data, the camera also uses sound waves to send the data to a receiver that reconstructs the image. Those sound waves could come from any source, like a passing ship or marine life. As it doesn’t need a power source, the camera could run for weeks on end before getting it back, enabling scientists to search remote parts of the ocean for new species.
Now that researchers have demonstrated a working prototype (原型), they plan to enhance the device so it is practical in real-world settings. For future application, these cameras may be used to take images of ocean pollution and create more accurate models to monitor climate change to better understand how climate change impacts the underwater world, and advance various undersea scientific fields.

6 . “I spilled soup all over the table, but it wasn’t my fault”. “I got into trouble at school, but it wasn’t my fault.” Such statements are often heard. “It’s not my fault” is actually a common response for so many people and especially teenagers. Parents complain that they’re tired of the “excuses”.
The reason why variations of “it’s not my fault” are so popular is that they get us out of guilt, blame and anger. Those emotions may come from others’ reactions or our own self-talks. In the case of adolescents, they are often trying to escape responsibility and punishment for mistakes.
Some teens would benefit from decreasing their self-blame. Those who blame themselves for things that they can’t control tend to be highly self-critical and are more likely to be anxious.
Many teens overly rely on “it’s not my fault”. However, overuse of the phrase can result in feelings of helplessness to control their own lives. Besides, “it’s not my fault” focuses a teen’s attention on what is done as opposed to what needs to be done. In trying to get them to assume responsibility, many parents attempt to convince their children that something is their fault, but the approach tends to be ineffective. A more effective approach is to face up to drawbacks to find solutions to the drawbacks actively.
People may not have caused all their problems, but they have to solve them anyway. Getting stuck in sharing blame often keeps people from moving forward effectively. What does one do if he is pushed into a deep lake? One could certainly stay in water, yelling, “It’s not my fault.” However, that is not going to get him out of water. At some point, he needs to swim to shore, regardless of the fault.
Like most things in life, freeing ourselves from blame has its advantages and disadvantages. The question isn’t what is “right”, but what is most effective in moving forward.

7 . Though it’s common that new scientists get international experience as part of their postdoctoral work, acquiring international exposure during one’s PhD study is less common. But it can be rewarding.
I’m in the final year of my PhD course in experimental physics. The PhD program is based at Loughborough University, the UK, but a big part of my experimental work is at the Max Planck Institute in Germany. Coming from England just after my bachelor’s degree in physics was a big step and somewhat risky. I wasn’t sure if it would help my career or suit my personal style. I was faced with a number of questions.
My supervisors (导师), one in England and one in Germany, gave me great freedom to pick research topics and carry out my research at another institute.
I was excited about going to the Max Planck Institute. Once the long road of the PhD is complete, I hope to have the confidence to compete in an increasingly multinational field in order to secure postdoctoral positions. Although moving abroad means reduced contact with my home university and research community, attending conferences in Britain has helped me network and develop a sense of community.
It took some time to settle down, find an apartment, and get used to the local life, surroundings and a different language. In the lab, a simple task was complicated by the language barrier. Still, with persistence, it was an enriching experience both personally and professionally. The Max Planck Institute provided not only an exciting environment, but enough funding that helped expand the output of my research considerably. I had access to equipment and resources hard to find at many institutions.
Thus far, I have no regrets. Doing a PhD abroad has improved my knowledge of physics and clarified my career aspirations (抱负).

8 . Sharks and their relatives are some of the most threatened vertebrates (脊椎动物) on Earth. Coral reefs (珊瑚礁) provide homes for countless fish species that are vital for fisheries and are therefore an especially important ecosystem for humans — and one where the decline of shark populations seems to be especially acute.
The study by Simpfendorfer will his team is the result of a worldwide collaboration called the Global FinPrint project. The data analyzed include more than 20,000 hours of standardized underwater video taken at nearly 400 reefs in 67 countries around the world. It reveals declines of 60 to 73% of once-abundant coral reef shark species at reefs around the world.
However, the findings of Simpfendorfer with his team include signs of hope and a clear path forward. Their results show that although shark populations in many reefs had declined, some healthy reef shark populations remained. The reefs with healthier shark populations had some important similarities: they tended to be in the waters of high-income countries with stronger natural resource management regulations. A country that lacks the resources to feed its people is less able to sustainably manage and protect its biodiversity.
The most unexpected result of the study is that a decline or complete loss of shark species in one reef was not always associated with similar changes in nearby reefs.They found that one reef can be over fished so badly that a once-common reef shark species is totally gone, but another reef a short distance away can have healthy populations of that same species.It is likely that healthy populations can eventually help repopulate nearby areas.
The problem is clear — animals that provide ecosystem services that are vital for human food security and livelihoods are disappearing at an alarming rate. The loss of sharks and the ecosystem services they provide represents an ecological disaster that can cause substantial harm to humans. But apparently, the findings have shown a way. If the threat that led to population decline are resolved, then these important and threatened animals may recover.

9 . Emotions play a critical part in our lives and are easy to spread among people unless you know how to actually control them. In order to grow and thrive, you must learn to be emotionally intelligent.
Focus Your Efforts On Self-evolution
Just like you, it is completely normal for everyone else to have their own beliefs and opinions. Keeping that in mind, it’s better to understand that you cannot change others, no matter how hard you try. Even if you try changing others, you could be hurting yourself in the process.
Try Using “I” Statements
People sometimes interact with us as if we are mind readers, especially in relationships. Your partner may expect you to understand their desires, which can be challenging. Just as you aren’t a mind reader, others aren’t either. You need to communicate your needs to other people, and they need to do the same with you. Share your needs with your loved ones and observe the positive changes.
Avoid Negative People
You are known by the company you keep, and this is always true.
A.Express Your Needs |
B.Always Be A Mind Reader |
C.If surrounded by happy and motivated people, you will always be happy |
D.When upset, express your feelings openly but in a non-aggressive manner |
E.The strategy in this stressful situation is to focus on others instead of yours |
F.Taking full responsibility for your actions is how you become emotionally mature |
G.To enhance emotional maturity and happiness, self-development is the best course of action |
