9 . Have you noticed that some people just seem to accomplish tons and still appear happy and relaxed? Here are some tips for making life more productive and fun.

Combine your activities

Many people go crazy trying to figure out how to spend time with friends, family, work, play, etc. Stop trying to balance time between them separately.     1    . Build your social life around people in your life. Find people in your life who share common interests and develop your career around the people and activities you love.

    2    

Under certain circumstances, social media, family, friends and co-workers all can waste your precious time if you let them. Budget your time for necessary activities. Make a choice to limit non-supportive interactions. As for social media, it can easily be a black hole for time and productivity.     3    , but stay away from the games.

Be an active learner

    4    , but actually there are always new tools and new ways of doing things that can save you time on daily tasks and free you up for more activities. Always look for a new way to gain back an hour here or there.

Lighten up

There is no need to beat yourself up if you can’t do all the things you want because you are handling other stuff that needs attention. It happens. The world won’t come to an end just because you leave a few things undone. Instead, celebrate your progress.     5    

A．Make a to-do list

B．Actively manage time-wasters

C．Find ways to enjoy them in a combined manner

D．You might think learning takes more time from you

E．Use it appropriately as a tool to support your needs

F．Every completion is a small victory that adds up in a big way

G．The things you do well usually give you greater joy and require less time

10 . A start-up company backed by tech giants IBM and Microsoft plans to build thousands of artificial reefs across the globe to fight climate change by restoring coral reef (珊瑚礁) ecosystems.

The Reef Company plans to have its first reefs in the water by December 2022, and is encouraging more companies to fund reefs to offset (抵消) their carbon footprint. “We’ve calculated we need to build 2,500 reefs, each measuring 4 square kilometers, over the next 10 years to absorb the extra carbon we have on the planet at the moment,” says Jeroen van de Waal, founder of The Reef Company.

Coral reefs are home to 25% of all marine life. They provide a source of income for millions of people through fishing and tourism and protect coastal communities by reducing the power of waves before they reach the shore. Yet they’re under threat from global warming and 90% of all coral reefs could be lost by 2050 if nothing is done to protect them.

As well as improving biodiversity and storing carbon, The Reef Company, which is based in Portugal, hopes to give a boost to local economies and collect real-time data for researchers.

The artificial reefs are constructed from eco-friendly concrete made from recycled industrial waste and will feature consoles (控制台) filled with sensors that can measure how salty, warm and acid the ocean is. “The reefs will provide a continuously expanding set of connected sensors to gather and analyze data, generating insights in real time,” says Andrés Ortolá, managing director of Microsoft Portugal.

To act as a sink for carbon dioxide, the artificial reefs will need to support plants such as seagrass and mangroves alongside coral. While coral reefs use carbon to grow, the process also lowers the pH in the water, which results in the release of CO₂. Benjamin Horton at the Earth Observatory of Singapore says artificial reefs will need to be well maintained to prove successful. “If the ecosystems are damaged, their carbon sink capacity will be affected, and the carbon stored will be released.”
