    At long last, Stefano Boeri Architects' brilliant Bosco Verticale towers are finally completed. The “world's first vertical forest” consists of a fantastic pair of costly towers that add nearly 2.5 acres of lush vegetation to the sky line of Milan, a city notorious (声名狼藉的) for its air pollution. {#blank#}1{#/blank#} Like a pair of green lungs, its forested appearance of 21,000 plants will absorb CO₂, control noise pollution, lessen the urban heat island effect, and create oxygen and favorable micro-climates.

    How you calm yourself before giving a speech? Both modern research and centuries of experience from experienced（有经验的）public speakers suggest some practical（实用的）advice.

    {#blank#}1{#/blank#}

Know to whom you'll be speaking, and learn as much about your audience（听众） as you can. The more you can expect the kind of reaction your listeners will have to your speech, the more comfortable you'll be in delivering your message. Be audience-centered rather than speaker-centered.

    {#blank#}2{#/blank#}

    You will feel less nervous if you talk about something you are familiar with or have some personal experience of. Your comfort with the subject of the speech will be reflected in your delivery.

    {#blank#}3{#/blank#}

    The better prepared you are, the less anxiety（焦虑）you will experience. Being prepared means that you have researched your topic and practiced your speech several times before you deliver it.

    {#blank#}4{#/blank#}

    You are likely to feel the most nervous during the opening moments of your speech. Therefore, it is a good idea to have a clear plan for how you will start your speech. Being familiar with your introduction（介绍）will help you feel more comfortable about the entire speech. If you know how you will end your speech, you will have a safe harbor in case you lose your place. If you need to end your speech ahead of time, a well-delivered conclusion can permit you to make a graceful exit.

    {#blank#}5{#/blank#}

    One of the symptoms(症状) of nervousness is a change in your breathing and heart rates. Nervous speakers tend to take short, shallow breaths. To help break the anxiety—reduce breathing pattern, consider taking a few slow deep breaths before you rise to speak.

A. Know your introduction and your conclusion(总结).

B. Channel（引导） your nervous energy.

C. Know your audience.

D. Use deep-breathing techniques.

    Here's how yo-yo dieting affects your body and your mind

    Yo-yo dieting, also known as weight cycling, occurs when a person experiences periods of weight loss followed by weight gain followed by weight loss and so on and so on. The effects of this weight cycling are significant, even when the weight lost and gained is as little as 10 pounds.{#blank#}1{#/blank#}

    It can make you gain weight

    While dieting may help you lose a few pounds at first, it only works temporarily. Your body responds to the lack of calories by turning to lean muscle mass for energy. Once you have returned to your normal eating habits, the weight comes back on –{#blank#}2{#/blank#}

    {#blank#}3{#/blank#}

    Yo-yo dieting may increase the risk for heart disease and sudden death in post-menopausal（绝经后期）women. Studies found that when normal-weight women experienced periods of weight cycling, they were 3.5 times more likely to have sudden death than women whose weight remained stable. In the same study, yo-yo dieting increased a woman's risk of death by 66 percent.

It can be damaging to your skin

    Dermatologist (a doctor who studies and treats skin diseases) Robin Evans weighed in on the effect that yo-yo dieting has on the skin. “The up and down weight losses and gains can have harmful effects on the skin especially on the face with stretching and contracting the skin,” said Evans{#blank#}4{#/blank#}.

It plays games with your mind

    Yo-yo dieting is hard on the body,{#blank#}5{#/blank#} Repeatedly gaining and losing weight can leave dieters feeling more depressed about their weight and losing self-belief as a result.

    If you're a yo-yo-dieter, talk to your health care provider about lifestyle changes that can help you maintain a stable and healthy weight for years to come.

A. It only works temporarily

B. It can damage your heart

C. but in the form of fat, not muscle

D. but it's even harder on the mind

E. but with a smaller size, you will make yourself less friendly

F. The result ends up more wrinkles and an overall effect of aging the skin

G. We turned to the experts to find out how yo-yo dieting can affect your body and your mind

    Healthy habits that stick

    Here are five rules that helped me develop good habits.

    ⒈Pick habits you honestly want to have

    I didn't choose habits I thought I should add because of what anyone else was doing. {#blank#}1{#/blank#} It was about listening to myself.

    ⒉Build your habit your own way

    When I started to build up an exercise routine(习惯), I only went when I wanted to go. For me, that was around 2 pm every day. {#blank#}2{#/blank#} If I wanted to do 20 minutes on the bike, I'd do only 20 minutes and then leave.

    ⒊Start small

    I knew that if I tried to take on too much, I'd find a way to make an excuse. {#blank#}3{#/blank#} I started with two minutes of exercise, which were finally built up to 10, then 20 minutes. I realized that just doing something, no matter how small, meant I was more likely to do it again the next day.

    ⒋Be kind to yourself

{#blank#}4{#/blank#} When I got a cold and missed several days of exercise, I didn't beat myself up. Instead of punishing myself, I tried to love myself — and that had a more enjoyable and lasting effect.

    ⒌Celebrate every small victory

    When I began keeping a diary every morning, I put a number in the corner of each page to show how many diaries I had written. {#blank#}5{#/blank#} Finally, after I filled up a notebook, I celebrated buying a new notebook.

A. If I missed a day, I let it go.

B. I can make exercise less boring.

C. So my daily purposes were very small.

D. I celebrated my pen running out of ink.

E. It wasn't about keeping up with other people.

F. I should celebrate my success with my friends.

G. It also meant that I would do whatever I wanted to do once I got there.

A travel journal is one of the best ways to keep a long voyage in memory. Many details that don't seem important while you are writing your travel journal often turn out to be so memorable.

{#blank#}1{#/blank#}. When you are on a busy journey, it is easy to forget to write. You may promise yourself that you will write later, but that almost never happens. Take a few minutes every day and put down your memories.{#blank#}2{#/blank#}.

Use your “down time” for your travel journal. There is a surprising amount of sitting around while traveling. You can always put down a few lines in your travel journal when you are on trains, waiting for planes, drying your laundry, or waiting in line.

At the beginning of your journal, write down the day, where you are, who you are with, maybe even the weather and what you eat. {#blank#}3{#/blank#}. Years later when you read your journal, you will know exactly what you were doing on that day.

Focus on writing about how you feel. Listing facts and figures is fine but that isn't why you traveled. A long journey is a time for self-reflection. Memories of these feelings fade quickly with time.{#blank#}4{#/blank#}.

{#blank#}5{#/blank#}. Whenever you use a ticket for a train or a museum or a ride, tape the stubs to your journal. They are pieces of history from your journey. Years later you can look at the ticket stubs and see exactly what you were doing on a specific day and how much it cost.

A. Keep ticket stubs.

B. Book your ticket in advance.

C. You'd better write down as much as possible.

D. These are the first details people tend to forget.

E. It doesn't have to be long, just on a regular basis.

F. Get into the habit of writing your travel journal every day.

G. Writing about those experiences while the memories are fresh is important.
