    Young sunflowers face the sun as it rises in the east and follow it across the sky until it sets in the west. Why does this happen? A team of scientists has finally been able to figure{#blank#}1{#/blank#} how and why young sunflowers move.

    Older sunflowers always face east. However, as it{#blank#}2{#/blank#}(turn) out, an internal（内部的）clock helps young sunflowers track the sun so that they can grow better. US biologist Stacey Harmer and her colleagues had it{#blank#}3{#/blank#}(explain) in a recent paper published in the journal Science on Aug. 5.

    {#blank#}4{#/blank#}(depend) on the time of day, certain growth genes seem to work to different degrees on different{#blank#}5{#/blank#}(side) of young sunflowers' stems（茎）. The east side of their stems grows faster during{#blank#}6{#/blank#}day, causing the stems to {#blank#}7{#/blank#}(gradual) bend from east to west. The west side grows faster at night, preparing them for the next morning.

    All this move is highly{#blank#}8{#/blank#}(benefit) to sunflowers. The team found that flowers kept away from the sun had leaves{#blank#}9{#/blank#}were 10 percent smaller on average. According to Harmer, sunflowers which{#blank#}10{#/blank#} (face) with the sun receive more bees and other insects because they like warm flowers.

There is one famous poem in Tang poetry, which reads: "I left home when a mere young man, and returned in old age. My native accents {#blank#}1{#/blank#}(remain) unchanged, but my ear - lock had grown thin". This poem {#blank#}2{#/blank#}(apparent) shows language is not only a tool for communication, but also the indicator of people's cultural identity. In a linguistic(语言学的)sense, dialect refers to the variety of a specific language {#blank#}3{#/blank#}( cause) by different geographical, social and cultural contexts.

Owing {#blank#}4{#/blank#}the vast areas and large population of China, diverse dialects can {#blank#}5{#/blank#}(find) in this great land, such as the Wu dialect in Shanghai, Hakka and Cantonese. However, it cannot be denied that since the popularization of Putonghua in China, the importance of dialects is lowering among Chinese people. To make matters {#blank#}6{#/blank#}(bad), some dialects have even disappeared due to the adoption of Putonghua {#blank#}7{#/blank#} is required in public places like schools and companies. {#blank#}8{#/blank#}(consider) the cultural significance of dialects, nowadays both Chinese {#blank#}9{#/blank#}(official) and common people are paying careful attention to {#blank#}10{#/blank#} preservation of dialects because it's the treasure of Chinese culture and art.
