How to improve your vocabulary

    Vocabulary is a key part of learning a new language. {#blank#}1{#/blank#}  Maybe you can't learn a hundred new words a day, but you can learn one or two a day, totaling thousands of new words over the years. Here are some tips for building up your vocabulary.

    Make a plan to learn new words. If you want to improve your vocabulary more quickly, you have to make at least a small promise. {#blank#}2{#/blank#}

Make you vocabulary practical（实用的）. {#blank#}3{#/blank#} For example, learn more of your trade language—- the words that are commonly used in your business or hobby or vocation(职业). Find better, fresher, clearer words to express what your friends are talking about.

    {#blank#}4{#/blank#} As you read, if you come across a new word that you don't understand. Don't miss it. Take the time to look it up in a dictionary. Write it down and use it later.

    When you learn a word, use it immediately and frequently. Put your new word into conversation with as many different people as you can. {#blank#}5{#/blank#} Use it in sentences. Write it on a card and practice it while waiting for red lights.

A. Repeat it to yourself.

B. They're highly reusable

C. Start learning where you are.

D. Decide to learn one new word every day or two.

E. When you're writing something, use a dictionary frequently

F. Start by learning the words that can express what's most important to you.

G. The more you read, the more words you'll see, and the more you'll understand.

Grandparents Answer a Call

    As a third generation native of Brownsville, Texas, Mildred Garza never planned to move away. Even when her daughter and son asked her to move to San Antonio to help their children, she politely refused. Only after a year of friendly discussion did Ms Garza finally say yes. That was four years ago. Today all three generations regard the move as a success, giving them a closer relationship than they would have had in separate cities.

    No statistics show the number of grandparents like Garza who are moving closer to the children and grandchildren. Yet there is evidence suggesting that the trend（趋势）is growing. Even President Obama's mother-in-law, Marian Robinson, has agreed to leave Chicago and into the White House to help care for her granddaughters. According to a study grandparents com., 83 percent of the people said Mrs. Robinson's decision will influence the grandparents in the American family. Two-thirds believe more families will follow the example of Obama's family.

    “In the 1960s, we were all a little wild and couldn't get away from home far enough or fast enough to prove we could do it on our own,” says Christine Crosby, publisher of Grand a magazine for grandparents. “We now realize how important family is and how important it is to be near them, especially when you're raising children.”

    Moving is not for everyone. Almost every grandparent wants to be with his or her grandchildren and is willing to make sacrifices, but sometimes it is wiser to say no and visit frequently instead. Having your grandchildren far away is hard, especially knowing your adult child is struggling, but giving up the life you know may be harder.

    Starbucks will stop using plastic straws from its stores globally by 2020, in a nod to the growing push for businesses to be more environmentally friendly. The Seattle-based company said on Monday it will instead use straws made from other materials, and lids designed not to need straws. McDonald's also recently said it would switch to paper straws in the UK and Ireland by next year, and test alternatives to plastic straws in some US locations. In February, Dunkin' Donuts said that it would refuse polystyrene foam (塑料泡沫) cups from its stores by 2020.

    Environmental activists have been pressuring businesses to ditch plastic straws because they can end up in the ocean and hurt marine life. The push gained great support after a video in 2015 showed rescuers removing a straw from a sea turtle's nose in great detail. Local governments have also been looking at the issue. Last week, Seattle's ban on single-use plastic straws and utensils in food service outlets took effect, and Starbucks says it already offers alternative straws there. Similar proposals are being considered elsewhere, including New York and San Francisco.

    While straws have become a highly-concerned issue, they make up only about 4% of the plastic trash by number of pieces, and far less by weight. Straws add up to only about 2,000 tons of the nearly 9m tons of plastic waste that hits waters each year.

Senses That Work Together

    When we think about how our senses work, we usually imagine them operating separately: you sniff a flower, and the smell is delivered uninterrupted from nose to brain. However, it's more complex than that. Most evidence for cross modal perception (知觉) comes from studies into sound and vision (视觉). But research that shows other senses crossing over is coming out all the time, and it seems that even sound and smell sometimes form an unlikely pairing.

    When New York researchers, Daniel Wesson and Donald Wilson, tried to find out the truth about a "mysterious” area of the brain called the olfactory tubercle, they had to deal with this fact. Originally, they only intended to measure how olfactory tubercle cells in mice responded to smell. But during testing, Wesson noticed that every time he put his coffee cup down, the mouse cells jumped in activity. In fact, the olfactory tubercle is well-placed to receive both smell and sound information from the outside world. Later they found that among separate cells, most responded to a smell but a significant number were also active when a sound was made. Some cells even behaved differently when smell and sound were presented together, by increasing or decreasing their activity.

    Of course, mice aren't people, so research team has been carrying out further experiments. They pulled together a group of people and gave them various drinks to smell. Participants were asked to sniff the drinks, and then match them to appropriate musical instruments and produce the notes at different levels. The results were interesting: piano was regularly paired with fruity fragrances; strong smells sounded like the instruments that are made of metal.

    Further research found that listening to different sounds can change your perceptions. Studying taste this time, the team ordered some special toffee (太妃糖) and put together “soundscapes” corresponding to bitterness and sweetness. Participants tasted similar pieces of toffee while listening to each soundscape, and found the toffee more bitter or sweeter, depending on which soundrack they were listening to.

    Studies like this are helping scientists correctly describe our understanding of the senses, and how the brain combines them with its advantage. The consequences are worth considering. Could we see musicians work together with chefs to produce sound-improved food and drink? Will you be ordering a coffee with a soundrack to bring out your favorite smell? Come to think of it, that could be one thing you hope coffee shop chains don't get round to.

English businessman Richard Branson made history on July 11, 2021 as he and three other crewmates became the world's first space tourists. The flight was made by a spacecraft named VSS Unity that was built by Branson's company, Virgin Galactic. The flight lasted slightly more than an hour, and took Branson and crew to an altitude（海拔） of 53. 5 miles above the Earth, just a little above the boundary（边界） of space which lies 50 miles above the Earth.

At that height, the atmosphere turns into the black of outer space and the Earth becomes a bent ball of blue. Travelers also exhibit weightlessness as there is no gravity, the force that keeps our bodies walking on the Earth's surface. Therefore, Branson and his fellows were able to float around in VSS Unity while enjoying the views. They were able to do that for three minutes before the spacecraft began its downward journey. It landed back at Virgin Galactic's space port in New Mexico, United States, which is the same place from where it took off 90 minutes ago.

On landing back, Branson said, "I have dreamt of this moment since I was a kid but honestly, nothing could prepare you for the view of the Earth from space. It was just magical. I'm just taking it all in, and it's unreal."

July 11's flight is the start of space tourism for one and all. In early 2022, customers who could afford a ticket for a quarter of a million dollars could line up for a seat on a trip to space. And guess what—they will have a choice of spacecraft. Jeff Bezos, who owns a famous company, is all set to launch himself into space on July 20 on board a spacecraft built by his new branch company Blue Origin. Blue Origin will also carry tourists to space.

We've all heard the advice to "get out of your comfort zone" by taking on a new challenge. A recent study goes a step further: Make discomfort a direct goal. That's more likely to motivate you {#blank#}1{#/blank#} if you only focus on what you hope to learn.

In the first of five experiments, the researchers assigned several hundred students training at Second City Chicago {#blank#}2{#/blank#}（participate） in a small-group improvisation（即兴） exercise, and then instructed half of the group that their goal during the session was "to feel awkward and uncomfortable." The rest, {#blank#}3{#/blank#}（that） in the control group, {#blank#}4{#/blank#}（tell） to "feel yourself developing new skills." Members of the first group kept at the exercise longer than the others did and took {#blank#}5{#/blank#}（great） risks.

Experiments {#blank#}6{#/blank#}（involve） other dimensions of personal growth—engaging in expressive writing, learning about gun violence, and hearing about opposing political {#blank#}7{#/blank#}（belief）—produced similar results.

Reframing anxiety as excitement has been proven a way to improve singing in front of strangers, and thinking of stress as {#blank#}8{#/blank#} means to boost achievement demonstrated a stress-management technique.

"When people reinterpret negative experiences as {#blank#}9{#/blank#}（function）, they are more willing to engage in tasks that call forth those experiences," the researchers explain. "Instead of seeing discomfort as unrelated to the goal {#blank#}10{#/blank#} a signal to stop, they will start perceiving it as a sign of progress toward their goal."
