Benefits of Deep Cleaning Your Home
The researchers have discovered an average of 7,000 different types of bacteria per household.
One study shows the dirtiest objects in the home found over 340 different bacteria on 30 different objects. So what actually are the benefits of deep cleaning? Let’s find out!
1.Dust can cause sore eyes, coughing, hay fever (花粉病) and asthma (哮喘) attacks.2.For instance, dust can be found behind cabinets, on top of doors, windows and so on. Deep cleaning involves cleaning those places to wipe out the dust particles around them. With the absence of dust particles in the air, it will help improve the air quality in your home significantly.
Remove harmful bacteria and viruses.3.Some bacteria divide every 20 minutes with the right temperature and nutrients. Places like the kitchen, living room, and especially toilets contain the most bacteria and viruses. Quick wipe downs are quick and convenient but it’s ineffective, only a deep clean can eliminate the majority of bacteria and viruses laying around.
Reduce stress. People might find it odd how deep cleaning can actually reduce stress levels in the house. It may not be obvious but when conducting deep cleaning, you will be moving, rearranging and organizing household items. 4.You may even need a helping hand with getting rid of the large amount of clutter (杂乱物) around the house.
So, by deep cleaning your house every so often, you can get rid of clutter and the trouble of misplacing items around the house.5.
A.Separate dust particles.
B.Better indoor air quality.
C.Dirty homes are shelters for bacteria and viruses.
D.Dirty and messy homes are linked to many illnesses and infections.
E.There are more dust particles lying around your home than you know.
F.You will meet useless items by accident laying around for who knows how long.
G.You will even be awarded extra living space from removing all that dust-collecting items.
“Jewel wings fly around like little helicopters until they see preys (猎物), usually smaller flying insects,” said Bellido, a biologist at the University of Minnesota. “Then they dash at their meals in a burst of speed.”
You might mistake jewel wings for their cousins, dragonflies. New research shows that these two insects share something more significant than their appearance, however. In a paper published in Current Biology, Dr. Bellido and the dragonfly colleagues reveal that the neural (神经的) systems behind jewel wings’ vision are shared with dragonflies, with whom they have a common ancestor that lived before dinosaurs. But over the centuries, this brain wiring has adapted itself in different ways in each creature, enabling sharply different hunting strategies.
Jewel wings’ behavior involves attacking what’s directly in front of them, the team found. But recordings made in the lab by Dr. Gonzalez and her colleagues confirmed that dragonflies rise up in a straight line to seize unsuspecting insects from below. Researchers are particularly interested in the neurons (神经元) that send visual information to the wings.
To look closer at the neurons linking vision and flight, the researchers equipped jewel wings with sensors and showed them a video of a moving dot, comparing it with earlier dragonfly research. When a neuron fired, a popping sound filled the researchers’ ears, allowing them to tell exactly which movements-left, right, up, down or some combination-each neuron responded to. Jewel wings best see what’s right in front of them, they found, while dragonflies’ clearest vision is just above them.
The team was interested to find that while jewel wings’ neurons didn’t always respond like those in dragonflies, the number of neurons and organization were similar. That suggests that the system that conveys this information from the eyes to the wing muscles did not evolve recently, but has roots that are millions of years older than the oldest dinosaurs. And that ancient common ancestor likely had already developed remarkable speed in both vision and flight. Then, in the following years, the system has evolved to suit individual insect species.
This shared neural system may be more than 250 million years old, but it is also flexible enough to transform itself to meet the needs of a variety of creatures in different eras and environments, the findings suggest.

With schools close in the UK during the COVID-19 outbreak, most children must now be homeschooled. Parents have found themselves not only having to balance work and having the children at home but also having to try and teach them. How can you keep your children focused while learning?
Nicola Anderson--Head of Customer Support at the UK’s leading online tutoring service MyTutor, provides new, up-to-date tips to hearten parents at this difficult time and advises how they can structure their children’s days.
One is to keep to a regular timetable so it still feels like your child is taking part in the school day. Ms Anderson said: “Children of all ages do well on routine and boundaries; schools provide this in abundance and it will most children feel secure and happy if they can follow a similar timetable for their homeschooling.”
Another tip is to create an environment which is favorable to learning. She said:” The environment should be free from distractions and ideally near to an open window, to provide them with appropriate levels of fresh air and natural light. Some children find it comfortable and helpful to have quiet, instrumental music playing in the background to help them to focus, but this isn’t for everyone.”
Using technology to help with your child’s learning is also advised. Many schools are offering online classes and resources to help and companies are reducing or even not charging their fees during this time.
It is also important to keep physical exercise as a part of your routine. Joe Wicks, otherwise known as The Body Coach, has been keeping kids healthy with daily 10 minute workouts for children on his Youtube channel. Ms Anderson said:” It can be anything from running around the garden, walking the dog, a game of football or dancing around your living room!”

Autumn Peltier is a youth environmentalist who has inspired thousands of students to walk out of class and demand action on climate change.
When Autumn Peltier was just 8 years old, she attended a ceremony at a reservation where she saw a sign warning that the water was poisonous. Growing up on a freshwater island in Wiikwemkoong Unceded Territory in Canada, Peltier says she had never experienced poisonous water. The memory of that sign stayed with her.
Two years later, at the age of 10, Peltier is fighting for water conservation and water rights for everybody. She says she was inspired by her great aunt, Josephine Mandamin, a well-known activist who walked the shores of all five Great Lakes to raise awareness for water conservation.
When she was 12 in 2015, Peltier met Canadian Prime Minister Justin Trudeau, telling him she was unhappy with his policies on debating pipeline projects. Trudeau promised her he would preserve the water. Since 2015, 87 long-term water advisories in Canada have been lifted; 56 water advisories remain.
At middle school, Peltier joined an environmental group at her school and later co-founded the Canadian Youth Water Strike-a Canadian branch of the international movement to conserve water.
Last year, Peltier spoke at the UN about the importance of water conservation and water access, explaining the fundamental role water plays in her culture.
“Many people don’t think water is alive or has a spirit. My people believe this to be true. . . . We believe our water is precious because we are born of water.”
After the speech at the UN, Peltier is joined by a group of teenagers who share similar thoughts. Her friends include Greta Thunberg, a Swedish girl who drew the world attention through the talk at World Economic Forum at Davos, Bruno Rodriguez, an Argentinian boy who joined in the UN Climate Summit, and Mari Copeny, an American girl who is dedicated to the cause of saving water. Peltier and her friends believe that together they can make a big difference.
Undoubtedly, Peltier’s many years of hard work has paid off. She has greatly raised people’s awareness of water conservation and taught people to take specific actions to conserve water.
That’s an impressive list of accomplishments for anyone, let alone a middle schooler.
1.How did Peltier feel about the poisonous water when she was 8?
A.Shocked. B.Interested. C.Excited. D.Bored.
2.Who influenced Peltier to start water conservation?
A.UN officials. B.Trudeau. C.Mandamin. D.Thunberg.
3.What does Peltier expect to do in the future?
A.To make more friends. B.To protect more water.
C.To attend more summits. D.To organize more strikes.
4.What can we learn from Autumn Peltier’s story?
A.World leaders can contribute to success.
B.Environment is Canadians’major concern.
C.Fame comes from attending great summits.
D.Achievements result from continuous effort.
