Tips to stay safe and make smart choices

    Even if you're a genius (天才) at school, you still might be lost when it comes to getting from point A to point B. Don't get caught in a strange place without these basic safety tips.

    Know where you're going.

    Before you set out in an unfamiliar area, go to Google Maps to plan your journey and print it out. {#blank#}1{#/blank#} Make sure that the location services are turned on your phone, just in case you get lost.

    Know where your stuff is.

    Never leave your backpack or shopping bags out of your sight. Carry your wallet in your front pocket or keep it close to your body. {#blank#}2{#/blank#} A fun day out can turn into the worst headache ever if you realize you've left something behind.

    {#blank#}3{#/blank#}

    If you have the choice between a busy street and a deserted one, always pick the busy one. You are more likely to be attacked on dark, empty sidewalks than on ones with a crowd.

    Travel in packs.

    Don't go anywhere — especially an unfamiliar place — without a friend or two. {#blank#}4{#/blank#}

    Don't let your music drown you out.

    Traditional Chinese medicine (TCM) isn't supported by most Westerners. {#blank#}1{#/blank#}

    TCM will be included in the new version of the International Classification of Diseases (ICD), which will be published by the World Health Organization in 2019, Nature magazine reported. {#blank#}2{#/blank#} Ryan Abbott at the Center for East-West Medicine at the University of California, Los Angeles, US, said this could benefit TCM.

    {#blank#}3{#/blank#} For example, during the 2016 Rio Olympic Games, US swimmer Michael Phelps was seen with circular bruises(瘀青) on his body. Such bruises are caused by cupping, a traditional Chinese medicinal practice that has been around for more than 2,000 years.

    In 2015, Chinese scientist Tu Youyou was awarded the Nobel Prize in Medicine for her discovery of artemisinin(青蒿素), a drug that can cure malaria(疟疾). She said she was inspired by traditional Chinese medicine.

    {#blank#}4{#/blank#} Twenty-six TCM centers were set up overseas over three years, according to a 2017 report published by Xinhua News Agency.

    TCM still faces many challenges, such as a lack of clinical evidence as to precisely how it works. {#blank#}5{#/blank#} Some say that TCM methodology should be combined with modern scientific methods to make it more acceptable to people outside of China.

A. However, this is starting to change.

B.TCM has cured millions of people in the world.

C. China has made some efforts to promote TCM overseas.

D.TCM's effectiveness has been difficult to study or provide evidence for.

    What happens when you want to go from one place to another, but there's water in the way？That's the problem people faced for hundreds of years in the area that is now New York City. In the city, there is a natural canal called the Narrows, separating Brooklyn on one side from Staten Island on the other.

    But the Narrows isn't really so narrow. The water is almost a mile wide, and it's more than 100 feet deep. {#blank#}1{#/blank#}When they wanted to talk to each other, they climbed into their boats and sailed across.

    By the late 1800s, circumstances had changed dramatically. Population growth meant there were now many people needing to travel between Staten Island and Brooklyn for work. {#blank#}2{#/blank#}

    Between 1888 and 1920 there were two major efforts to build a train tunnel to connect the areas. {#blank#}3{#/blank#} Proposals to build a connecting bridge made during the 1910s also ended in failure due to opposition from the US Navy.

    Finally, after World War II, there were so many people living in New York City that leaders decided Brooklyn and Staten Island needed a direct connection. Since tunnels were too expensive, they decided to build a bridge. The design selected had two separate roadways stacked on top of each other. {#blank#}4{#/blank#}Construction, which took five years, was completed in 1964 and cost $320 million. Today about 190,000 cars and trucks cross the bridge every day.

    {#blank#}5{#/blank#} But in the case of the Narrows, figuring out a good solution took hundreds of years.

A. Sometimes getting from one place to another is easy.

B. Both were quickly abandoned however due to the high costs involved.

C. Neither road was large enough to satisfy the existing transport demands.

D. It was anticipated that the new train system would help the areas grow even faster.

E. Taking a boat every time was very slow, expensive and, in bad weather, unreliable.

F. Both would hang in the air from thick steel cables, supported by two giant steel towers.

G. For a long time that wasn't a problem, because only a few people lived in Brooklyn and Staten Island.
