Writing text messages while walking is dangerous. A study says it is more dangerous than texting while driving. Researchers found that there are more {#blank#}1{#/blank#} (injury) to texting pedestrians(行人) than there are to texting motorists. Their report says walking is not as easy {#blank#}2{#/blank#} we think. We must focus on many things at the same time to walk safely in a straight line. The researchers said that people forget how to walk {#blank#}3{#/blank#} (proper), so dangerous things happen to them. They bump(撞) into walls and other people. They walk into cars, fall over things in the street, {#blank#}4{#/blank#} even fall into holes.

    A professor said walking is a difficult action. There are several reasons {#blank#}5{#/blank#} texting makes walking dangerous. {#blank#}6{#/blank#} is that people cannot see the street. Another is that they focus on their phone keyboard instead of their feet. A final reason is that their minds are somewhere else—they are not thinking about {#blank#}7{#/blank#} (walk) from A to B safely. The professor said over 6,000 people {#blank#}8{#/blank#} (visit) his hospital last year because of texting. He said {#blank#}9{#/blank#} worst cases are head injuries. When a pedestrian is tossed into the air he/she has nothing {#blank#}10{#/blank#} (protect) the head. The damage can be serious.

    You might want to think twice before purchasing{#blank#}1{#/blank#}(conventional) grown strawberries or spinach(菠菜). According to a new report from the Environmental Working Group(EWG), these foods are the most likely{#blank#}2{#/blank#}(pollute) with the pesticide.

    Even low levels of pesticide exposure can be harmful to infants, babies and young children,{#blank#}3{#/blank#}parents and caregivers should take measures to lower children's exposures{#blank#}4{#/blank#}pesticides while still{#blank#}5{#/blank#}(feed) them diets rich in healthy fruits and vegetables.

    Just last year, the red berry knocked apples and{#blank#}6{#/blank#}(hold) the title of the most polluted. The pesticide increased in strawberries because of out-of-season demand. The most polluted strawberry had traces of 20{#blank#}7{#/blank#}(vary) pesticides.

    Also moving up on{#blank#}8{#/blank#}list this year is spinach. Spinach jumps from the{#blank#}9{#/blank#}(eight) to the second most polluted product. The study finds spinach samples contain more pesticides by weight than all other produce{#blank#}10{#/blank#}(test). In high doses, it can cause damage to the nervous system.

    Chengdu, capital city of southwestern China's Sichuan Province{#blank#}1{#/blank#} (name) one of the top ancient capitals in China at a conference{#blank#}2{#/blank#} (hold) on Oct. 25^th, 2016. Along with Chengdu, nine other cities, including Beijing, Xi'an, Nanjing and Luoyang,{#blank#}3{#/blank#} (be) also on the list.

    As one of the cradles (摇篮) of Chinese civilization, Chengdu has a history of more than 4,500 years. It is one of the {#blank#}4{#/blank#} (old) cities in China, even in the world, having been the capital of five major states.{#blank#}5{#/blank#} addition, Chengdu has done a good job preserving{#blank#}6{#/blank#} (it) history. The location, name, and center of the city have never been changed, which reflects{#blank#}7{#/blank#}(clear) the city's vitality (活力) and cultural identity.

    “Chengdu has a unique spirit, related to inclusiveness and independence,” said the president of a(n){#blank#}8{#/blank#} (associate) of ancient Chinese capital studies. “Chengdu is{#blank#}9{#/blank#} open and influential city in Chinese history. So, there is no doubt {#blank#}10{#/blank#} it is an important and famous capital.”
