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.

    What can keep your brain young and active? Marie Pasinski{#blank#}1{#/blank#} doctor from Massachusetts General Hospital, says, “New experiences as well as a good snack.”

    The next time you feel{#blank#}2{#/blank#} (bore) at the pool, play a board game or cards. Exercising your mind with a challenging game that requires brainpower,{#blank#}3{#/blank#} chess or bridge (桥牌), is more than just fun. These types of games are so interesting{#blank#}4{#/blank#} they can build up working memory. Traveling, especially in the places where English isn't spoken, can make you{#blank#}5{#/blank#} (smart) and more intelligent. There is a great deal of recent research proving its benefits.

    Being overweight can cause depression even when no other health problems exist, according to a study released Tuesday by the University of Exeter.

    A team {#blank#}1{#/blank#} (lead) by researchers from the University of Exeter analyzed UK Biobank data (基因数据库) from more {#blank#}2{#/blank#} 48,000 people with depression and {#blank#}3{#/blank#} (compare) them to another group of more than 290,000 people.

    While {#blank#}4{#/blank#} has long been known that depression is more common in obesity, the team concluded {#blank#}5{#/blank#} higher body mass index(体重指数) can cause depression in itself, even in the obese {#blank#}6{#/blank#} other health problems.

    Our genetic analysis concludes that the psychological impact of being obese is likely {#blank#}7{#/blank#}(cause) depression. This is important to help target efforts to reduce depression, {#blank#}8{#/blank#} makes it much harder for people to adopt {#blank#}9{#/blank#} (health) lifestyle habits, said Dr Jess Tyrrell. The team tested their results in many people and they reached {#blank#}10{#/blank#} same conclusion, verifying their results.

    The study has been published in the International Journal of Epidemiology.

    The Chinese Culture Center in Paris, {#blank#}1{#/blank#}(locate) in downtown areas opposite the celebrated historic sites of Grand Palais and Petit Palais across the Seine River, {#blank#}2{#/blank#}(sit) next to a large number of grand handsome and elegant classical architectures that have witnessed the evolution of Paris at {#blank#}3{#/blank#} (vary) historical stages. It conforms to(符合) the status of China, a great power with {#blank#}4{#/blank#} lasting civilization of several thousand years in the East, {#blank#}5{#/blank#} (set) the Chinese Cultural Center in this exact place.

    The amazing progress in {#blank#}6{#/blank#} (smooth) selecting the site for the Chinese Culture Center and putting it into {#blank#}7{#/blank#} (operate) in downtown Paris in such a short period was due to high priority of the Chinese government and constructive cooperation of the French party. Wu Jianmin, Chinese ambassador to France,  said {#blank#}8{#/blank#}excitement, "We have our own cultural center in Paris at last, {#blank#}9{#/blank#}we have eventually realized the long cherished wish of my predecessor(前任) in the Chinese embassy." Hou Xianghua, the first director of the Chinese Cultural Center in Paris, said the center will stick to its "non-governmental" nature and greet people from all {#blank#}10{#/blank#} (walk) of life, in addition to serving the mainstream society.
