Once there was a little boy. He got angry easily. His father gave him some nails (釘子)and told him: “When you get angry, put a nail into the wall.”
On the first day, the boy put 37 nails into the wall. The next day, he put in fewer nails. A few days later, he found it much easier not to get angry.
After a while, the boy was happy every day.
Then, his father asked him to take out a nail each day if he didn’t get angry. After some time, all the nails were gone.
Then the father took the boy to the wall and said: “Well done, son. But, look, the wall is full of holes. It will never be the same. When you say things in anger, they leave a scar(傷疤) in people’s hearts（心）. No matter how many times you say sorry, the scars will always be there.”

Once a baby cries, the parents will go to see what happened as soon as possible. According to a new study, a baby’s cry can make adults react very quickly, even if they are not related(相關(guān)的).
Oxford University researchers used a game called Whack-a-mole for the study. The game needs people to hit one buttons(按鈕). The players must react as quickly as they can to hit the button that lights up at random(隨機的). It is a game that requires speed and accuracy(準(zhǔn)確度).
The study included 40 men and women volunteers aged 19 to 59. Some of them had sons or daughters but none had a baby at the time. They played whack-a-mole after listening to different sounds, including babies’ crying, the crying of adults in trouble and birds’ song that sounds like babies’ crying.
The volunteer’ scores  were higher after listening to the sound of crying babies. Men and women had similar scores. The results showed that a crying baby gets special attention.
“Few sounds make people react quite like the cry of a baby,” said Morten Kringelbach of Oxford’s psychiatry department, who led the study.
He added that a baby’s cry can increase adults’ heart rate and blood pressure. This is understandable, because in the course of human evolution(進化), taking care of babies has always been an important job for adults. When a baby is hungry or feeling bored or unwell, it will cry. As a result, human brains and bodies develop a special reaction to a baby’s cry.
小題1:According to the passage, how many volunteers took part in the study?
A．80B．40 C．19D．59
小題2:In the passage, the underlined word react means__________.
A．表演B．打擊C．反應(yīng)D．演示
小題3:The game “whack-a-mole” shows__________.
A．a(chǎn) baby’s cry can get special attention from adults
B．men and women have different reaction speed and accuracy
C．a(chǎn)dults without babies react more quickly to a baby’s cry
D．women react to a baby’s cry more quickly than men
小題4:According to the passage, a baby’s cry__________.
A．can get the same attention from adults as the birds’ song
B．is the noisiest sound
C．can increase adults’ heart rate and blood pressure
D．is good for its health
小題5:From the last paragraph, we learn that_________.
A．taking care of the younger babies was the most important thing in the past
B．human brains and bodies have developed to take care of babies
C．baby cries are a good way make adults react quickly
D．baby cries have developed a lot during the course of human evolution

Can plants eat people? Probably not, but there are many plants that eat meat. Some of them are big. And they can eat small animals. One famous meat-eating plant is the Venus flytrap(捕蠅草).
The Venus flytrap is a very strange plant. It grows in dry parts of the United States. Its leaves are like the pages of a book. They can open and close very quickly. Inside the leaves, there are three small hairs. If a fly touches one of the hairs, the leaf closes quickly. The fly cannot get out. In about half an hour, the leaf presses the fly until it is dead. Then, the plant covers the fly. Slowly, the plant eats the fly.
Why do plants do it? Most plants get what they need from the sun, the air, and the ground. In some places, the ground is very poor. It doesn't have all these important things, especially nitrogen(氮). Animal meat has a lot of nitrogen, so some plants eat meat to get what they need. Let's hope that some of the bigger plants don't get the same idea!
小題1:The Venus flytrap is a kind of _________.   
A．plantB．a(chǎn)nimalC．foodD．meat
小題2:The underlined word "presses" probably means _________ in Chinese．
A．?dāng)D壓B．關(guān)上C．打開D．松開
小題3:Why do some plants eat animal meat?
A．Because plants are dangerous to animals.
B．Because animals are dangerous to plants.
C．Because plants want to get what they need from animal meat.
D．Because plants want to protect themselves against animals.
