With an annoying mix of late trains, missed appointments and work deadlines, many of us are living in a constant state of stress. Experts warn, our modern lifestyles means that stress is almost continuous, and comes without the natural release that either fighting or fleeing might provide.{#blank#}1{#/blank#} Conditions vary from mood swings(情绪波动) to anxiety, irritability, nervousness and tiredness.

    Good morning everyone! Today I want to talk about how to deal with our children's homework. As we know, homework is a great way for children to develop learning skills. So as parents, you should pay attention to it.

    {#blank#}1{#/blank#}

    Avoid having your child do homework with the television on or in places with different noises, such as people coming and going.

    Make sure your child has all the materials he needs.

    Ask your child if special materials will be needed for some subjects and get them in advance.{#blank#}2{#/blank#}

    Help your child use time properly.

    Tell them not to watch TV unless they finish their homework in time.{#blank#}3{#/blank#}Don't let your child leave homework until just before bedtime.

    When your child asks for help, provide guidance, not answers.

    Giving answers means your child will not learn the material.{#blank#}4{#/blank#}At the same time, you should keep in touch with teachers, which shows your child that the school and home are a team.

    {#blank#}5{#/blank#}

    If your child has been successful in homework and is working hard, celebrate that success with a special event to make him happy.

    I am sure your child will be interested in doing homework if you take my advice.

    Things You Didn't Know About Stephen Hawking

    Even if you don't keep a close eye on new developments in physics, you've probably heard of the famous physicist Stephen Hawking.{#blank#}1{#/blank#}

    These days, we know Hawking as a brilliant mind whose theories are difficult for a nonscientific mind to grasp. This is why it may come as a shock to learn that Hawking was a slacker when it came to his school studies.

    {#blank#}2{#/blank#}With a little more effort, he brought those grades up to about average, but not much better. However, from an early age he was interested in how things worked. He has talked about how he was known to take apart clocks and radios. However, he admits he wasn't very good at putting them back together so they could work again.

    Stephen Hawking took a liking to mathematics from an early age, and he would have liked to have majored in it.{#blank#}3{#/blank#}He hoped Stephen would instead study medicine.

    But, for all his interest in science, Stephen didn't care for biology. He has said that he found it to be “too inexact, too descriptive (叙述的)”{#blank#}4{#/blank#}

One problem, however, was that Oxford didn't have mathematics as a major. The result was that Stephen would attend Oxford and major in physics. {#blank#}5{#/blank#}That's why he chose to study universe.

A. His father wanted to send him to Oxford.

B. His father, Frank, however, had different ideas.

C. Actually, he focused on the bigger questions.

D. He would have rather devoted his mind to more precise concepts.

E. In fact, when he was 9, his grades ranked among the worst in his class.

F. However, there're many interesting facts you might not know about him.

G. Both his teachers and peers seemed to understand that they had a future genius.

    Perhaps at one point in time, it was acceptable to start any letter or e-mail with “To Whom It May Concern.”{#blank#}1{#/blank#} Starting your cover letter or e-mail for a job this way might give off the impression that you didn't do your research on who you're writing to{#blank#}2{#/blank#}After all, people who address other people by their names when writing and speaking to them tend to be more pleasant.

    {#blank#}3{#/blank#}It can be used in letters of recommendation or reference, formal complaints（抱怨）made to a company, letters of introduction, and letters of interest.

    Grammarly uses the example of needing to write a letter of recommendation, for a colleague who will have to make several copies to distribute to interviewers{#blank#}4{#/blank#}“In most cases, though, try to narrow your focus rather than cast a broad net,” notes Grammarly.”Ask yourself. Who does this e-mail concern? If you can honestly answer 'Anyone, 'then feel free to use “To Whom It May Concern.” （These are the things you should never say in your cover letter.）

    If you do happen to find that using “To Whom It May Concern” is appropriate, don't make grammar mistakes, for example, letters or punctuation.{#blank#}5{#/blank#}

A. However, it maybe interesting.

B. Those times have changed, though.

C. Making mistakes in writing will surely get you low scores.

D. It's also very impersonal, which some employers might not appreciate.

E. In that circumstance, sending and receiving letters is more of a formal greeting.

F. You might want to take note of other common errors you might be committing, too.

G. But according to Grammarly, there are four times when it's OK to use this greeting.

    Imagine an area 34 times the size of Manhattan. Now imagine it covered ankle-deep in plastic waste—a total of about 19 billion pounds of garbage. {#blank#}1{#/blank#}.

    "We're being overwhelmed(淹没) by our waste," said Jenna Jambeck, an environmental engineer who led the 2015 study that determined this astonishing number. {#blank#}2{#/blank#}, unless something is done to stop the tide of garbage.

    Plastic—a widely-used material—has in many ways been a benefit to humans but it has also caused a growing problem. Today, plastics are the No.1 type of garbage found in the sea. Ocean Conservancy, a nonprofit that organizes an annual coastal cleanup event worldwide, said plastic waste makes up around 85 percent of the garbage collected from beaches and oceans.

    Ocean Conservancy says plastics are believed to threaten(威胁)at least 600 different wildlife species(物种). {#blank#}3{#/blank#}; a growing body of evidence suggests humans are consuming plastics through the seafood we eat. A research suggests some plastics could be poisonous to humans, and could potentially increase the risk of health problems.

    {#blank#}4{#/blank#}. At the Economist World Ocean Summit this week, ten nations announced to reduce plastic sea liter as part of UN Environment's CleanSeas campaign. {#blank#}5{#/blank#}Corporations also have a role, as do individuals. We can start by thinking twice before using single-use plastic products—and when we do use them, we should take care to properly throw them off or recycle.

A. The following is what we should do

B. And it's not just wildlife that's threatened

C. And this figure is likely to double by 2025

D. But it's not just countries that need to do their part

E. By 2050, that figure is expected to rise to 1000 pieces

F. That's how much plastic waste ends up in our oceans every year

G. All of us have an important role to play in dealing with the problems
