A person steps on what seems like solid ground but discovers with horror that the ground is giving way underfoot. The person struggles desperately but is trapped. There is no escape. Slowly the person sinks deeper and at last is gone. The solid ground was solid only in appearance. It was actually quicksand, which is a deep mass of fine sand mixed with water.
How is quicksand formed? Water pushes up from below the surface and is held by the sand. The grains of sand are forced apart by the water. They cannot hold any weight. The subsurface water may have come from a spring, a river, or a stream. Sometimes pools of water near beaches become filled with sand. When the soil under these pools does not allow for good drainage(排水), the sand can become stretches of quicksand.
Is it true that a person who steps into quicksand is doomed to die? No, for people have fought their way from quicksand to firm land again. It is panic(恐慌) that creates the condition that can result in death, for the more a person struggles, the worse matters become. Quick movements will make the sand yield for a time, but then it rushes back and settles solidly around the body.
People trapped in quicksand should either lie back with arms outstretched, or not move at all. When the weight of the sand around his body has displaced equals that person’s weight, the victim will stop sinking. With feet held still, and with slow movements of the arms, as in the backstroke(仰泳) in swimming, people have managed to roll to safety and reach firm ground. Quick movements by a person trapped in quicksand will _______.
| A．help the person reach firm ground |
| B．help prevent panic |
| C．make the same sand yield temporarily |
| D．make the sand hold the person’s weight |
Quicksand is _______.
| A．a mass of fine sand mixed with water | B．formed only along rivers |

Have you ever wondered why birds sing? Maybe you thought that they were just happy. After all, you probably sing or whistle when you are happy.
Some scientists believe that birds do sing some of the time just because they are happy. However, they sing most of the time for a very different reason. Their singing is actually a warning to other birds to stay out of their territory.
Do you know what a “territory” is? A territory is an area that an animal, usually the male, claims（声称）as its own. Only he and his family are welcome there. No other families of the same species (物种) are welcome. Your yard and house are your territory where only your family and friends are welcome. If a stranger should enter your territory and threaten you, you might shout. Probably this would be enough to frighten him away.
If so, you have actually scared the stranger away without having to fight him. A bird does the same thing. But he expects an outsider almost any time, especially at nesting（筑巢）season. So he is screaming all the time, whether he can see an outsider or not. This screaming is what we call a bird’s song, and it is usually enough to keep an outsider away.
Birds sing loudest in the spring when they are trying to attract a mate and warn others not to enter the territory of theirs.
You can see that birds have a language all their own. Most of it has to do with attracting mates and setting up territories.Some scientists believe that most of the time birds’ singing is actually __________.
| A．an expression of happiness | B．a way of warning |
| C．an expression of anger | D．a way of greeting |
What is a bird’s “territory”?
| A．A place where families of other species are not accepted. |
| B．A place where a bird may shout at the top of its voice. |
| C．An area for which birds fight against each other. |
| D．An area which a bird considers to be its own. |
Why do birds keep on singing at nesting season?
| A．Because they want to invite more friends. |
| B．Because their singing helps frighten outsiders away. |
| C．Because they want to find outsiders around. |
| D．Because their singing helps get rid of their fears. |
How does the writer explain birds’ singing?
| A．By comparing birds with human beings. |
| B．By reporting experiment results. |
| C．By describing birds’ daily life. |
| D．By telling a bird’s story. |
Some children are natural-born bosses. They have a strong need to make decisions, manage their environment, and lead rather than follow. Stephen Jackson, a Year One student, “operates under the theory of what’s mine is mine and what’s yours is mine,” says his mother. “The other day I bought two new Star Wars light sabers(剑). Later, I saw Stephen with the two new ones while his brother was using the beat-up ones.”
“Examine the extended family, and you’ll probably find a bossy grandparent, aunt, uncle or cousin in every generation. It’s an inheritable trait.” says Russell Barkley, a professor at the Medical University of South Carolina. Other children who may not be particularly bossy can gradually gain dominance（支配地位）when they sense their parents are weak, hesitant, or in disagreement with each other.
Whether it’s inborn nature or developed character at work, too much control in the hands of the young isn’t healthy for children or the family. Fear is at the root of a lot of bossy behavior, says family psychologist John Taylor. Children, he says in his book From Defiance to Cooperation, “have secret feelings of weakness” and “a desire to feel safe.” It’s the parents’ role to provide that protection.
When a “boss child” doesn’t learn limits at home, the stage is set for a host of troubles outside the family. The overly willful and unbending child may have trouble obeying teachers or coaches, for example, or trouble keeping friends. It can be pretty lonely as the top dog if no one likes your bossy ways.
“I see more and more parents giving up their power,” says Barkley, who has studied bossy behavior for more than 30 years. “They bend too far because they don’t want to be as strict as their own parents were. But they also fell less confident about their parenting skills. Their kids, in turn, feel more anxious.”Bossy children like Stephen Jackson __________.
| A．make good decisions | B．show self-centeredness |
| C．lack care from others | D．have little sense of fear |
The study on bossy behavior implies that parents __________.
| A．should give more power to their children |
| B．should be strict with their children |
| C．should not be so anxious about their children |
| D．should not set limits for their children |
Bossy children may probably become __________.
| A．relaxed | B．skillful |
| C．hesitant | D．lonely |
What is the passage mainly about?
| A．How bossy behavior can be controlled. |
| B．How we can get along with bossy children. |
| C．What leads to children’s bossy behavior. |
| D．What effect bossy behavior brings about. |
We have two daughters Kristen is seven years old and Kelly is four. Last Sunday evening, we invited some people home for dinner. I dressed them nicely for the party, and told them that their job was to join Mommy in answering the door when the bell rang. Mommy would introduce them to the guests, and then they would take the guests’ coats upstairs and put them on the bed in the second bedroom.
The guests arrived. I introduced my two daughters to each of them. The adults were nice and kind and said how lucky we were to have such good kids.
Each of the guests made a particular fuss over Kelly, the younger one, admiring her dress, her hair and her smile. They said she was a remarkable girl to be carrying coats upstairs at her age.
I thought to myself that we adults usually make a big “to do” over the younger one because she’s the one who seems more easily hurt. We do it with the best of intentions.
But we seldom think of how it might affect the other child. I was a little worried that Kristen would feel she was being outshined. I was about to serve dinner when I realized that she had been missing for twenty minutes. I ran upstairs and found her in the bedroom, crying.
I said, “What are you doing, my dear?”
She turned to me with a sad expression and said, “Mommy, why don’t people like me the way they like my sister? Is it because I’m not pretty? Is that why they don’t say nice things about me as much?”
I tried to explain to her, kissing and hugging her to make her feel better.
Now, whenever I visit a friend’s home, I make it a point to speak to the elder child first.The underlined expression “make a big ‘to do’ over” (Paragraph 4) means __________.
| A．show much concern about | B．have a special effect on |
| C．list jobs to be done for | D．do good things for |
The guests praised Kelly for carrying coats upstairs because of her __________.
| A．beautiful hair | B．pretty clothes |
| C．lovely smile | D．young age |
Kristen felt sad and cried because __________.
| A．the guest gave her more coats to carry |
| B．she didn’t look as pretty as Kelly |
| C．the guests praised her sister more than her |
| D．her mother didn’t introduce her to the guests |
We can conclude from the passage that __________.
| A．parents should pay more attention to the elder children |
| B．the younger children are usually more easily hurt |
| C．people usually like the younger children more |
| D．adults should treat children equally |
