A: Mary, tomorrow is your Mum's 50th birthday, do you know?

B: Of course I do. Do you have any idea about how {#blank#}1{#/blank#} (celebrate) it, Dad?

A: Of course, first of all, a birthday present. What about {#blank#}2{#/blank#} (buy) her a beautiful skirt?

B: That's a good idea. It'll make her look {#blank#}3{#/blank#}（young）. and a big birthday cake, too, with fifties {#blank#}4{#/blank#} (candle).

A: That's right. {#blank#}5{#/blank#}we have a special dinner?

B: How about a Chinese dinner?

A: Fine, where will we have it?

B: Dad, we can have it at home . I {#blank#}6{#/blank#} (learn) to cook a few Chinese dishes from a Chinese friend, {#blank#}7{#/blank#} I am sure Mum would like {#blank#}8{#/blank#}.

A: All right. Will you do {#blank#}9{#/blank#}shopping too?

B: {#blank#}10{#/blank#} don't we go together, Dad?

A: OK.

    Wherever you look these days something's looking back at you. There are video cameras on street {#blank#}1{#/blank#} (corner), vehicles and our own front doors.

    A Chicago company {#blank#}2{#/blank#} (call)Cooler Screens believes that you won't mind if they put cameras into the display cases (展柜) in stores. The cameras aren't placed there {#blank#}3{#/blank#} (prevent) you from stealing. Instead, they're part of a system that tries to guess {#blank#}4{#/blank#}you will buy next, based on how you look.

    The doors on the cases {#blank#}5{#/blank#} (be) video screens that show images of the goods, so a customer can see what's available inside. The screens also show vivid ads. They decide which ads to show by {#blank#}6{#/blank#} (study) video images of the customers.

    A camera feeds images of each customer into a computer {#blank#}7{#/blank#} guesses his or her sex and age. In addition, the system tracks {#blank#}8{#/blank#} (exact) where the customer is looking. Do the eyes come to rest {#blank#}9{#/blank#} a bottle of Red Bull, or does the shopper fancy Coca Cola? The Cooler Screens system instantly {#blank#}10{#/blank#} (analyze) all of this data, and then starts showing ads on the cooler door.

    Choice of seating in the lecture hall can affect a college student's performance, a study suggests.

    Lectures are a main part of higher education, and {#blank#}1{#/blank#}(understand) how students interact and learn within the lecture theatre environment is central to successful learning. Researchers from Sheffield Hallam University in the UK examined {#blank#}2{#/blank#} (student) reasons for choosing particular seats in a lecture hall, and investigated how seating positions are related {#blank#}3{#/blank#} students' performance.

    "Interaction is a key part of learning and knowing who the students are interacting with can be {#blank#}4{#/blank#} great benefit when designing activities," said David P Smith of Sheffield Hallam University.

    Many students {#blank#}5{#/blank#} (prefer) being able to sit with their friends, {#blank#}6{#/blank#} others were more concerned with either attracting or avoiding the lecturer's attention. Some students chose seats {#blank#}7{#/blank#} allowed them to see and hear clearly. But others {#blank#}8{#/blank#} (easy) picked seats that made them feel less depressed, they said.

    Friendship groups who sat together tended {#blank#}9{#/blank#} (achieve) similar grades, and students who sat alone at the edges were likely to do worse than average.

    Lecturers may be able to use these findings to offer assistance to {#blank#}10{#/blank#} (anxiety) students，and to support the learning of all students by encouraging interactions between the different groups.

    April Fool's day is a day {#blank#}1{#/blank#} people can play jokes on others. No one knows for sure how this holiday began. Some English people hold the {#blank#}2{#/blank#} (believe) that it began on the day during the 1200s. At that time, King John of England was in {#blank#}3{#/blank#} habit of making a road out of nearly every path he walked regularly. The citizens of one farm village were aware of this. To protect their grass and farms from being destroyed, they built a fence that prevented the king from walking through their countryside. The king sent a group of soldiers to inform the villagers to remove the fence. {#blank#}4{#/blank#} hearing that, however, the villagers developed a plan of their own. When the soldiers arrived, the villagers ran around and shouted wildly with things {#blank#}5{#/blank#} (throw) away everywhere, behaving as if they {#blank#}6{#/blank#}(go) mad. The soldiers reported to the king that they were so mad as to be beyond punishment. The villagers saved their farmland {#blank#}7{#/blank#} (success) by tricking the king. Now April's day {#blank#}8{#/blank#} (remain) in fashion, {#blank#}9{#/blank#} the tradition only allows tricks from midnight to noon on April 1st. Those who try to play tricks in the afternoon act as {#blank#}10{#/blank#}(fool) themselves and are usually laughed at.

    The man who is going to fix our roof must be {#blank#}1{#/blank#}(honest) person my husband and I have ever met.

    My husband knew the back roof of the porch was fine and wanted {#blank#}2{#/blank#}(see) what this roofer would say when he gave his estimate. He told my husband that the back roof was just fine and then gave the estimate for the rest of the roof:$2,400.

    He called last night to tell us he could do the roof on Monday but {#blank#}3{#/blank#}(tell) us he had measured the roof {#blank#}4{#/blank#}(correct) by forgetting to add on the front part of the roof.{#blank#}5{#/blank#} instead of giving us a new estimate, he told us he {#blank#}6{#/blank#}(go) to do the roof for what he quoted us.

    My husband asked him what the correct estimate would {#blank#}7{#/blank#}(be).He said,"$3,000."Well, that's what I had thought it would be so that's {#blank#}8{#/blank#} I set aside. My husband was simply {#blank#}9{#/blank#}(amaze) at this roofer.

    The roofer doesn't know our decision that he'll get the $3,000.He's honest and is planning to be responsible for the mistake. My boss was kind to me when I made some {#blank#}10{#/blank#}(mistake) in the past and now I get a chance to pass this on to others.
