Why men wolf down their meals {#blank#}1{#/blank#} women take their time? Many a woman has watched in disbelief as their partners eat their food minutes after sitting down to dinner. Now Korean researchers have discovered why: men and women {#blank#}2{#/blank#} (actual) chew differently. Women chew each individual mouthful more times — taking longer to finish {#blank#}3{#/blank#} (eat) their meal.

    The researchers hired 24 males and 24 females in South Korea. They recorded the size of people's bites, total chewing time per mouthful of food, total number of chews and how long {#blank#}4{#/blank#}   took the person to eat the entire meal. Men typically take {#blank#}5{#/blank#}   (large) bites with more “chewing power”, {#blank#}6{#/blank#} means they consume their meal more quickly than women.

    Though women were watched {#blank#}7{#/blank#} (have) the same chewing pace as men, they chewed each mouthful more times, slowing down the total time it took them to eat their meal.

    The study {#blank#}8{#/blank#} (publish) in the January issue of the Physiology and Behaviour Journal. But it flies in the face of an earlier result studied {#blank#}9{#/blank#} researchers at Nippon Dental University in Tokyo, Japan, which found no {#blank#}10{#/blank#} (different) in how the sexes chewed gum.

    I like my new teachers very much because they are kind and{#blank#}1{#/blank#}(patience). Several days ago{#blank#}2{#/blank#}(want) to do some revision for my English class. I usually enjoy{#blank#}3{#/blank#}(do) that but I couldn't understand the text I was reading. I felt{#blank#}4{#/blank#}sad that I nearly cried. Then I remembered that Mr. Smith,{#blank#}5{#/blank#}new English teacher, had told us that we could ask him about things we didn't understand at any time. I wrote down{#blank#}6{#/blank#}couple of questions and put them to Mr. Smith and he gave me a really clear{#blank#}7{#/blank#}(explain).

    I really appreciated{#blank#}8{#/blank#}(have) so many good teachers like Mr. Smith. They made me feel cared{#blank#}9{#/blank#}(immediate) I entered the school. I'm sure everyone of us has shown respect{#blank#}10{#/blank#}them.

    Beijing Opera roles require performers to paint {#blank#}1{#/blank#}( they) faces in patterns and colours to suggest different character types and{#blank#}2{#/blank#}(quality).

    In Beijing Opera, facial painting can be quite complex(复杂的). However, in the {#blank#}3{#/blank#}(begin), only three colours{#blank#}4{#/blank#}(use)-red, white and black. Now, many other colours, such {#blank#}5{#/blank#}yellow, purple, blue and green, are used for facial painting.

    Red is a colour for{#blank#}6{#/blank#}(brave) and loyalty. Guan Yu, a general from the Three Kingdoms Period(AD 220-280) is a good example of this kind of character. He is famous {#blank#}7{#/blank#}being very loyal to his emperor, Liu bei.

    White means all{#blank#}8{#/blank#}is bad in human nature. One of the typical white-faced characters is Cao Cao, a{#blank#}9{#/blank#} (power) and cruel prime minister from the Three Kingdoms Period.

    Black face paint is {#blank#}10{#/blank#}(usual) used for someone who is fierce and violent. One typical example is General Zhang Fei from the classic novel, The Romance of the Three Kingdoms.

    All these different colours are used in Beijing Opera facial painting to show a clear picture of each character.

    Nobody wants to be aged, but{#blank#}1{#/blank#}it comes to visiting cities, most of us want to visit the world's oldest cities. Luoyang is one of the oldest and most {#blank#}2{#/blank#}(attract) cities in the world that I'd like to recommend to you.

    Luoyang stands out{#blank#}3{#/blank#}The oldest continually inhabited (持续居住的) city in Asia. The city is considered to be{#blank#}4{#/blank#}birthplace of Chinese culture and history as well as being one of the Seven Ancient Capitals of China. There  {#blank#}5{#/blank#} (be) no other city in China that has seen so many{#blank#}6{#/blank#}dynasty) like Luoyang.

    With such a long and exciting history, Luoyang has really a lot{#blank#}7{#/blank#}(offer). The longmen Grottoes(龙门石窟), which{#blank#}8{#/blank#}(include) in the world Heritage List since 2000, and many historic Buddhist temples{#blank#}9{#/blank#}(constant) attract tourist from all over the world. Luoyang is also famous for the White Horse Temple, the earliest Buddhist temple{#blank#}10{#/blank#}build) in China. Are you anxious to visit the city?

The distance between ancient Rome and ancient China was about 4,000 miles by land. It was a very {#blank#}1{#/blank#} (danger) trip with deserts and mountains. The Silk Road was a nickname for any route {#blank#}2{#/blank#} any trader took from China to Rome.

For a very long time, the ancient Romans did not know who was making the wonderful cloth {#blank#}3{#/blank#} (call) silk. They tried to find the traders as they came into villages to trade other goods for silk, but the traders {#blank#}4{#/blank#} (hide) from the Romans. Therefore, they had to trade for it {#blank#}5{#/blank#} (themself). The trading along the Silk Road was a relay system. One trader would travel for a while, stop and trade, and return home. {#blank#}6{#/blank#} next traveler would continue. And so it went. But {#blank#}7{#/blank#} (actual) no trader made the whole trip. It was too risky.

As the years went by, a civilization of sorts grew up along the Silk Road. Temples appeared. There were even cities built on the rare oasis (绿洲). It was never easy{#blank#}8{#/blank#} (travel) by land from China {#blank#}9{#/blank#}Rome, but it was worth it. Rome traded gold for China's silk and spices. But {#blank#}10{#/blank#}(many) things traveled the Silk Road than traders and goods. Ideas that changed the world traveled along the Silk Road as well.
