Dear Tom，

    How time flies! You {#blank#}1{#/blank#} (study) in Beijing for nearly a month, during which you must have achieved a lot. Well, how's everything going? It is reported that the weather there is very hot and dry these days, which is very different from{#blank#}2{#/blank#} of your country. Have you adapted to it? In addition, you once complained that the food {#blank#}3{#/blank#} (serve) there was not {#blank#}4{#/blank#} your taste. I hope that should have been improved.

    I am glad to tell you that I will go to Beijing to take part in an English speech contest in July, {#blank#}5{#/blank#} is not only an honor, but also a great opportunity for me to improve {#blank#}6{#/blank#}. And now I try my best to make {#blank#}7{#/blank#} (prepare) for it. {#blank#}8{#/blank#}, I have some trouble in collecting the materials relevant and using the language. I will appreciate {#blank#}9{#/blank#} if you give me a hand to solve the problems.

    After the contest, I am to drop {#blank#}10{#/blank#} at your school to visit you. Please wait for my phone.

M: I'd like to know something about your educational background, Miss King. Your major is English, isn't it?

W: Right. I {#blank#}1{#/blank#}(graduate) from Harvard University in 2010.

M: Fine. And could you please tell me {#blank#}2{#/blank#} you have got any working experiences?

W: Well, I`m working for Singapore Airlines at {#blank#}3{#/blank#} moment, in their San Francisco office.

W: {#blank#}4{#/blank#}(exact) speaking, what are you there now?

W: I work in the department of sales promotion.

M: I see. And how long have you been working there?

W:{#blank#}5{#/blank#} two and a half years.

M: Would you mind {#blank#}6{#/blank#}(tell) me your present salary?

W: I`m making ＄2,280 a month at present. And I know your starting salary of this position is about＄ 2,600 a month.

M: That's right.

W: I`d like to know if your company provides opportunities for {#blank#}7{#/blank#}(far) education.

M: Yes, our employees {#blank#}8{#/blank#}(allow) to take up six hours a week at full pay to attend college courses.

W: That's very generous.

M: Well, I`ve enjoyed talking with you and we will phone you {#blank#}9{#/blank#}(late)

W: Thank you. I'd appreciate {#blank#}10{#/blank#} if you could inform me as soon as possible.

    Modern-day robots are programmed to handle tasks that are normally carried out by humans. They are faster and{#blank#}1{#/blank#}(accurate) than human workers and never ask for a pay rise or take breaks!

    Robots are also able to work{#blank#}2{#/blank#}dangerous situations.

    Researchers at the University of Arkansas in the United States say that the mobile robots which have been created already are ideal for the job of hospital attendants. These mobile robots store a{#blank#}3{#/blank#}(detail) map of the hospital in their memory. The robots' sensors can detect{#blank#}4{#/blank#}(object) and quickly get out of the way. Although these robots cannot go up and down know how{#blank#}5{#/blank#}(press) a button of an elevator.

    Researchers at a Massachusetts' university are creating the first robot {#blank#}6{#/blank#}can constantly change its shape according to the task it has to do. These are called polymorphic robots. "Polymorphic" means{#blank#}7{#/blank#}ability to take different forms. A 3D printer{#blank#}8{#/blank#}(place) inside the robot to create the desired shape. The entire process of changing forms in this manner is called the rapid printing technology which is{#blank#}9{#/blank#}(fair) common in the car industry to produce complex 3D structures quickly. Once the robot has performed{#blank#}10{#/blank#}(it) task, it can be melted down and recycled into another useful part by the 3D printer.
