Studying in groups is becoming more and more popular in class. It has many{#blank#}1{#/blank#} (advantage). For example, we can not only save time but also encourage each other when we study {#blank#}2{#/blank#}groups. I still remember when I was in Grade 8, my physics {#blank#}3{#/blank#}(be) very poor. I had{#blank#}4{#/blank#}really hard time with it. Once in class, the teachers asked{#blank#}5{#/blank#}to discuss it with each other, but I was very shy, I could not do it like what they told me. My physics teacher encouraged me to face others and talk with someone else{#blank#}6{#/blank#}(brave). Then I studied with some classmates together. When I did not understand any questions, they could give me some advice, I could quickly find out the ways{#blank#}7{#/blank#}(deal) with the problems. After that, I felt very relaxed and asked my classmates a lot of questions about physics. I did not feel stressed out at all. At last, I finished my homework {#blank#}8{#/blank#}myself for the first time. How {#blank#}9{#/blank#}(excite) I was!

    At least thirty times Bobby had tried to climb the snowy mountain, but he Because of {#blank#}10{#/blank#}(study) in groups, I am not worried about physics any more. With my classmates' help, I get more confidence. It also gives me more chances to improve myself in many ways.

    Traditional Chinese culture places much emphasis (重视) on food. Considered to be an important part of each day, {#blank#}1{#/blank#}(eat) is far beyond simply meeting a need. However, people are living in fast-paced society now, so they hardly have time to enjoy their food. They need fast food. That is {#blank#}2{#/blank#} China's fast-food market expands.

    A foreign fast-food restaurant {#blank#}3{#/blank#}(call) KFC arrived in China first, quickly followed by {#blank#}4{#/blank#}（other ）such as Pizza Hut and McDonald's. With{#blank#}5{#/blank#}the (develop) of China, foreign fast-food chains are realizing high-speed{#blank#}6{#/blank#}(grow) in China. However, these “junk foods” have long been criticized by health experts because {#blank#}7{#/blank#} (their) can't provide balanced nutrition(营养). The experts also show that some foreign fast food contains a food coloring, Sudan I, {#blank#}8{#/blank#}can cause cancer.

    In fact, China has many of its own traditional fast-food dishes. Among them, dumplings, soybean milk and noodles {#blank#}9{#/blank#}(be) the most popular. Compared with foreign fast food, those traditional ones are healthier. {#blank#}10{#/blank#}many Chinese still enjoy the special taste and the good environment in the foreign fast-food chains even though there exist some potential（潜在的）risks.

    Happiness can be described {#blank#}1{#/blank#} a positive mood and a pleasant state of mind. There are many factors {#blank#}2{#/blank#}(contribute) to happiness.

    A person in an apparently ideal situation is not {#blank#}3{#/blank#}(necessary) happy. The ideal situation may have little to do with his actual feelings.

    A good education and income are usually considered necessary for happiness. Though both may contribute, {#blank#}4{#/blank#} are only chief factors if the person is seriously undereducated or actually suffering from lack of physical needs.

    The rich {#blank#}5{#/blank#}(be) not likely to be happier than the middle-income group or even those with very low incomes. People with college educations are somewhat happier than those who did not graduate from high school, and it {#blank#}6{#/blank#}(believe) that this is mainly.{#blank#}7{#/blank#} they have more opportunity to control their {#blank#}8{#/blank#}(life). Yet people with a high income and a college education may be less happy than those with the same income and no college education.

    Poor health does not rule out happiness except for the severely {#blank#}9{#/blank#}(disable) or those in pain. Learning {#blank#}10{#/blank#}(cope)with a health problem can contribute to happiness.

    Celebrities(名人)like Olivia Munn, as well as fashion companies like Cucci and Versace , are among those who have been opposed {#blank#}1{#/blank#} wearing animal fur. Now, San Francisco has become the {#blank#}2{#/blank#}(large) city in the USA to ban retailers from selling new fur to their customers.

    The ban aims to send {#blank#}3{#/blank#} strong message to the fur industry {#blank#}4{#/blank#} the cruelty these animals endure for the purpose of {#blank#}5{#/blank#} (become) clothing is not consistent with the value of the city.

    As we all know, West Hollywood became the first American city {#blank#}6{#/blank#}(forbid)the sale of new fur items in 2011, and Berkeley passed a ban on the sale of fur clothing in 2017. Additionally, in 2000, the UK led the charge(打头阵), {#blank#}7{#/blank#} (follow) by Australia in 2004. More recently, the Netherlands, the European Union's main producer of fur , banned fur farming in 2012 and plans to end mink(貂) farming by 2024. In 2018, Norway banned fur farms and {#blank#}8{#/blank#}(end) fox and mink farming by 2025.

    Hopefully, only when efforts like these are made to encourage {#blank#}9{#/blank#} (consume) to stop buying real animal fur {#blank#}10{#/blank#} the lives of animals be further protected all over the world.
