Alice: Mr. Black, this is Alice {#blank#}1{#/blank#} (speak). I'm calling to ask you if I can take the afternoon off today.

Black: Well, of course. {#blank#}2{#/blank#} can you tell me what the problem is, Alice?

Alice: OK, Mr. Black. My son is going to take part in a singing competition {#blank#}3{#/blank#} (hold)  in Washington tomorrow. He's got so many things to take {#blank#}4{#/blank#} he can't go there alone.

Black: So you want to take {#blank#}5{#/blank#} there in your minibus?

Alice: Yes. And as soon as I put him up in the hotel, I {#blank#}6{#/blank#} (drive) back.

Black: Well, that would be a {#blank#}7{#/blank#} (tire) journey. It's nearly 300 kilometers away and it will take you at least six hours {#blank#}8{#/blank#} (travel) to and from Washington. Why don't you stay there until you  {#blank#}9{#/blank#} (see) your son perform?

Alice: But I have two {#blank#}10{#/blank#} tomorrow morning.

Black: Don't worry. I'll tell Mary to take your classes instead. She's always willing to help.

Alice: That'll be nice. Thank you and give my thanks to Mary.

Black: You,re welcome.

    Texting while walking is something that most of us are guilty of．We can't help {#blank#}1{#/blank#}(reply)to that message we just received．However，while it's fun to keep up to what's going on，we may actually put{#blank#}2{#/blank#}(we)in danger．

    A team of researchers from UK recently found people{#blank#}3{#/blank#}use their phones while on the move walk differently．During the research，a group of 21 volunteers{#blank#}4{#/blank#}(ask)to walk around a street with obstacles(障碍物)such as a step.{#blank#}5{#/blank#}volunteers traveled the course a total of 12 times each，either writing or reading a message，making a call，or with no phone at all．It took the volunteers 118 percent {#blank#}6{#/blank#}(long)to complete the course while using a phone．They also paid attention to the travel path 51 percent more when they weren't using a phone．“Although there{#blank#}7{#/blank#}(be)no accidents，we should still be aware{#blank#}8{#/blank#}what's going on around us，”according to Matthew Timmis，co—author of the study．The big risk is suddenly—appearing situations，like someone suddenly walking in front of you．You are not going to be able to respond to that{#blank#}9{#/blank#}(swift)enough，so you may injure yourself or get injured．In a word，these hidden{#blank#}10{#/blank#} (danger)of texting while walking should be recognized to avoid injuries．

    Many people keep small fish {#blank#}1{#/blank#} pets. They keep them in a tank (鱼缸) of water. The tank {#blank#}2{#/blank#} (make) of glass. People can look through it. They can see inside the tank and watch the fish.

    The fish need room. They mustn't be crowded. They need oxygen {#blank#}3{#/blank#} (breath). There must be enough water for all fish. So the size of the tank is very {#blank#}4{#/blank#} (importance).

    In the tank people put small plants {#blank#}5{#/blank#} are good for fish. They give oxygen to the water. Plants help in other ways, too. They can hide {#blank#}6{#/blank#} the plants and sleep, lay eggs there.

    The fish should {#blank#}7{#/blank#} (keep) in water all the time. Some can jump high. So the tank should be covered. This keeps the fish from {#blank#}8{#/blank#} (jump) out.

    The fish need food and should be fed every day. But if you give them too much food, it is very bad, for the extra food {#blank#}9{#/blank#} (fall) to the bottom and make the water dirty. So the fish should get just enough food and finish {#blank#}10{#/blank#} in ten minutes. Nothing should be left.
