Share your stress

It helps to talk to someone about your anxieties and worries. Perhaps a friend, family member, teacher or even your leader can help you a better view of what's troubling you. ____53______Knowing when to ask for help is an important step in avoiding serious problems later.

Make a list of the things you need to do

高三英语单项填空简单题查看答案及解析

Bombardier beetles are known for their skillful response to predators (捕食性动物).If they are about to be eaten, the insects spray their predators with boiling-hot chemicals. If they get swallowed anyway, they have plan B: Blast (爆炸) their way out from the inside.

In an experiment, scientists watched as a Japanese stream toad readily swallowed an Asian bombardier beetle. But 44 minutes later, the toad vomited (呕吐) the contents of its stomach. The insect ran away, physically unharmed.

“The vomited beetle was alive and active,” study authors Shinji Sugiura and Takuya Sato of Kobe University in Japan reported in the journal Biology Letters. Why, the researchers wondered, does luck always favor the escape artists? To find out, they needed more of them, and they needed to feed them to more toads. Scientists gathered 15 species of ground beetles, including the bombardier beetle. They also collected Japanese common toads, which are natural bombardier beetle predators, and Japanese stream toads, which do not live in the same place as the insect.

Sugiura and Sato hypothesized (假设) that over years of exposure, the common toad species developed a greater tolerance to the bombardier beetle's poisonous chemicals than the stream toads had. The bombardier beetles were divided into two groups. Some were poked (戳) with special tools, which caused them to release all their poisonous chemical spray. Other beetles were left alone. Then they were fed to the toads.

The toads that swallowed a fully loaded bombardier beetle were in for a surprise. “An explosion was heard inside each toad, which indicates that the bombardier beetle sent up a chemical spray after being swallowed, the authors wrote. The common toads vomited their prey 35 percent of the time. The stream toads vomited their prey 57 percent of the time. That confirmed their hypothesis about the toads' evolutionary adaptation. All 16 of the vomited insects were “alive and active” 20 minutes later. Almost all the beetles that released their defensive chemicals before meeting the toads were “successfully digested”. The test told the researchers that the beetles' boiling chemical spray was indeed their ticket to freedom.

1.When Bombardier beetles are in danger, they can ______.

A.have relevant ways to escape B.bring up the content of stomach

C.cause damage to their enemies D.make no response to outside attack

2.What was the scientists’ assumption before the experiment?

A.Bombardier beetles were always lucky to escape.

B.Japanese common toads were natural predators.

C.Common toads had the ability to resist the poison.

D.Bombardier beetles could release poison constantly.

3.What do we know about Sugiura and Sato’s test?

A.It showed the process of the insects’ evolution.

B.It demonstrated the harm of explosion in the toads.

C.It stressed the importance of a balanced ecosystem.

D.It provided convincing evidence for their assumption.

高三英语单项填空简单题查看答案及解析

D

Three Central Texas men were honored with the Texas Department of Public Safety’s Director’s Award in a Tuesday morning ceremony for their heroism in saving the victims of a fiery two-car accident.

The accident occurred on March 25 when a vehicle lost control while traveling on a rain-soaked State Highway 6 near Baylor Camp Road. It ran into an oncoming vehicle, leaving the passengers trapped inside as both vehicles burst into flames.

Bonge was the first on the scene and heard children screaming. He broke through a back window and pulled Mallory Smith, 10, and her sister, Megan Smith, 9, from the wreckage.

The girls’ mother, Beckie Smith, was not with them at the time of the wreck, as they were traveling with their baby sitter, Lisa Bowbin.

Beckie Smith still remembers the sickening feeling she had upon receiving the call informing her of the wreck and the despair as she drove to the scene.

Bozeman and Clemmons arrived shortly after Bonge and helped rescue the other victims and attempted to put out the fires.

“I was nervous,” Bozeman said. “I don’t feel like I’m a hero. I was just doing what anyone should do in that situation. I hope someone would do the same for me.”

Everyone at the accident made it out alive, with the victims suffering from nonlife-threatening injuries. Mallory Smith broke both femurs(股骨), and Megan had neck and back injuries. Bowbin is still recovering from a broken pelvis(骨盆), ankle and foot.

The rescuers also were taken to the hospital and treated for cuts and smoke breathing, Bonge said.

In addition, Bozeman got to meet accident victim Anthony Russo in the hospital after the accident, where Russo presented him with a glass frame inscribed(刻;雕 )with “Thank you,” Bozeman said. Those involved in that fateful encounter on Highway 6 credited God blessing for bringing them together.

“Whatever the circumstances, Tuesday’s ceremony provided a time to be grateful for those who put their lives on the line for the lives of complete strangers,” Beckie Smith said, “We’re calling it The Miracle on Highway 6.”

53. What’s the main idea of the passage?

A. Three persons were awarded for rescuing victims in a car accident.

B. Three ordinary people were regarded as great heroes.

C. Several victims were carried to safety from the burning cars.

D. A car accident occurred on a rain-soaked State Highway 6.

54. Who saved Megan Smith from the damaged car?

A. Clemmons.           B. Anthony Russo.          C. Bozeman.      D. Bonge.

55. Which of the following can be used to describe Bozeman?

A. Kind.                  B. Modest.                           C. Excited.       D. Smart.

56. It can be inferred from what Beckie Smith said that _______.

A. she regarded the accident as a wonder

B. she was frightened by the serious accident

C. she thought highly of the rescuers

D. she called on others to learn from the rescuers
