{#blank#}1{#/blank#} is well known, optimism(乐观)plays an important role in one's life. Although we are facing many difficulties, we should keep optimistic. Optimism is a mental(精神的)attitude or world view and it means expecting {#blank#}2{#/blank#} best possible result from any given situation.

    I did {#blank#}3{#/blank#} (poor) in English in the past, but I never gave up struggling(搏斗). All my families, teachers and friends encouraged {#blank#}4{#/blank#} (I) and they taught me a lot of {#blank#}5{#/blank#} (use) ways of learning English. I {#blank#}6{#/blank#} (keep) practicing as they told me to do. I listened to English news and songs and I read interesting English stories. At weekends, watching some English movies was another good way to make my English better. {#blank#}7{#/blank#}difficulties I came across, I tried my best to work them out. I believe in myself, {#blank#}8{#/blank#} (believe) that hard work would finally pay off. Gradually, I make progress in my English. Nowadays, I can remember English words {#blank#}9{#/blank#} (easy) and use them freely when communicating with foreigners.

    Thanks to optimism, I have become one of the top English {#blank#}10{#/blank#} (learn) in my school now.

    In recent years many TV shows have become extremely popular among Chinese audience. Those programs, ranging {#blank#}1{#/blank#} talent or dating shows to reality shows,{#blank#}2{#/blank#} (receive) both commercial success and public attention.

Their popularity is {#blank#}3{#/blank#} (main) based on simple facts. First, they care about social concerns. Second,  without exception, they explore a perfect balance between the international forms and Chinese expressions.

    Despite apparent highlights,  much room {#blank#}4{#/blank#} (leave) for improvement. Above all, commercial interests often outweigh  {#blank#}5{#/blank#} (education) purposes , causing many {#blank#}6{#/blank#} (complain) about the unbearable advertisements. In addition, some sharp remarks,{#blank#}7{#/blank#} they are eye-catching, may have misleading effects {#blank#}8{#/blank#} the youth.

    In my opinion, such shows should shoulder more responsibility instead of merely {#blank#}9{#/blank#} (entertain) the public.{#blank#}10{#/blank#} is expected, these programs should be positive in their forms as well as functions. Meanwhile, the media should also safeguard the values of our society.

    If you're a fan of penguins, you might enjoy{#blank#}1{#/blank#}(participate) in a new research project to help scientists measure changes to penguin populations.

    The project {#blank#}2{#/blank#} (name) Penguin Watch and the members are counting penguins in online {#blank#}3{#/blank#} (photo) taken across Antarctica, helping scientists monitor the species in their natural habitat. Up to now, nearly 40,000 volunteers have joined in the project.

    “Penguin Watch is people-powered research{#blank#}4{#/blank#} people can help and every click {#blank#}5{#/blank#} (matter) in helping us to understand penguins,” Tom Hart, {#blank#}6{#/blank#} expert from Oxford University and a member of the Penguin Watch team, told The Telegraph.

    The data {#blank#}7{#/blank#} (give) by volunteers will also help measure changes in not only the penguins' behavior and habitat, {#blank#}8{#/blank#} the larger ecosystem as well. “Finally, this huge data set allows us to {#blank#}9{#/blank#} (effect) train computers to take over from humans and helps us pass on the tools developed for penguins to the species {#blank#}10{#/blank#} threat,” said Hart.

    Believe it or not, have you ever noticed that you feel happier and more relaxed after you eat bread, pasta or fruit? Do you find that you are more energetic and awake after eating yogurt or beans? These things are not accidents. Food affect {#blank#}1{#/blank#} we feel more than we think. Scientists researching {#blank#}2{#/blank#} (it) effect on our moods are beginning to understand that we can influence our feelings with what we eat.

    Although our moods relates {#blank#}3{#/blank#} having various foods, it is not quite as simple as choosing the foods for the right occasions. If that {#blank#}4{#/blank#} (be) the case, athletes would not eat a lot of carbohydrates before a race.

    Another chemical {#blank#}5{#/blank#} (connect) with our mood is caffeine, which {#blank#}6{#/blank#} (find) in coffee, chocolate and many types of tea, is perhaps {#blank#}7{#/blank#} worst thing you can have when you are feeling stressed.

    Of course, {#blank#}8{#/blank#} (enjoy) a nice meal with friends, whatever we eat, can also impact our spirits. Being with friends and family plays a big part in experiencing happiness.

    Robot teachers are now very popular with pupils in some primary schools in South Korea. Compared with human teachers, the robot teachers are {#blank#}1{#/blank#} (patient). They never get angry and are always kind to the students. That's {#blank#}2{#/blank#} the children can always get on well with their robot teachers.

    English-teaching robots {#blank#}3{#/blank#} (send) to three primary schools for eight weeks last December. {#blank#}4{#/blank#} (equip) with a microphone and video camera, the robots teach students as teachers. Researchers found that the English-teaching robots helped raise students' interests in the language and build up their {#blank#}5{#/blank#} (confident). More and more students came to like studying and they got better grades in exams. Meanwhile, other robot teachers, {#blank#}6{#/blank#} can teach math, science and art, have also been developed.

    Many people think these robot teachers should be used {#blank#}7{#/blank#} faraway village schools so that the children there can also receive a good education. {#blank#}8{#/blank#} (give) rural school children more learning chances, the South Korean government has expressed great interest in {#blank#}9{#/blank#} (develop) these robots. No doubt there will be more and more robot teachers working with students. Perhaps they will {#blank#}10{#/blank#} (complete) replace human teachers one day in the future. Who knows?
