【改编】Our body clock，or natural body rhythm，influences our energy and alertness．Paying attention to it can help us choose the suitable time of day when we best perform specific tasks．
The reality，however，is that most of us organize their time around work demands，school deadlines，commuting or social events．Doing whatever your body feels like doing is a luxury in today's fast-paced modem society．
But that doesn't mean it isn't worth trying．Obeying our body clock has significant health benefits．Disrupting our natural body rhythm，on the other hand，has been linked to problems such as depression，obesity，or headache，says Steve Key，a biology professor．
When the body clock can synchronize（使……同步）the rhythms of its natural processes，it “gives us an advantage in daily life”，says Key．
According to him，when it comes to cognitive（认知的）work，most adults perform best in the late morning．As our body temperature starts to rise just before awakening in the morning and continues to increase until midday，our memory，alertness and concentration gradually improve．
However，he adds，our ability to concentrate typically starts to decrease soon thereafter．Most of us are more easily distracted between noon and 4 pm．
Alertness also tends to fall after eating a meal and sleepiness tends to peak around 2 pm，making that a good time for a nap．
Surprisingly, tiredness may increase our creative powers．For most adults，problems that require open ended thinking are often best dealt with in the evening when they are tired， according to a study in the journal Thinking & Reasoning．
When choosing a time of day to exercise，paying attention to your body clock can improve results．Physical performance is usually best from about 3 to 6 pm，says Michael Smolensky，a professor of biomedical engineering．
Of course, not everyone's body clock is the same，making it even harder to synchronize natural rhythms with daily plans．What does the writer mainly tell us in the passage?
| A．The benefit of natural body rhythm. |
| B．A new research about our body clock. |
| C．Something about natural body rhythm. |
| D．The definition of natural body rhythm. |
What is the meaning of the underlined word “disrupting”?
| A．Following. | B．Destroying. |
| C．Noticing. | D．Finding. |

| B．people are most focused at 3 o’clock.. |
| C．natural body rhythm can’ t influences people’s energy. |

Getting close to active or erupting volcanoes can be dangerous. But for Michael Rampino, it’s all in a day’s work. Rampino is a volcanologist, a scientist who studies volcanoes and how they affect our planet. Rampino has been close to red-hot lava flows (熔岩流) in Hawaii and explosive volcanoes in Indonesia. He knows when to get close to an active volcano and when to back away.
Rampino wasn’t always a volcanologist. He worked for NASA for seven years. He studied rocks until he began to research climate change and the effects that volcanoes have on climate. He became interested in the subject. “Once I started working with volcanoes,” Rampino said, “I was hooked.”
Rampino is a professor at New York University. As part of his job, he travels to areas where volcanoes have been active. “Active” means they have erupted within the past few centuries and probably will erupt again. Rampino studies the deposits (沉积物) of ash and other materials from the eruptions. The ash may hold clues to what happened to the Earth in the distant past. It may also help scientists predict what could happen to Earth’s climate in the future.
Rampino doesn’t work alone. He works with a team of scientists who use computers to stimulate (模拟) the effects volcanoes have on Earth’s atmosphere.
Being a volcanologist may be hard work, but it’s also fun. “It’s cool traveling the world studying “to understand the events that have shaped Earth’s history.”To Rampino, being close to active volcanoes is _____.
| A．scary but necessary | B．adventurous but meaningful |
| C．impossible and unnecessary | D．dangerous but urgent |
The underlined word “hooked” in Paragraph 2 probably means “_____”.
| A．trapped | B．touched | C．attracted | D．frightened |
Rampino’s study on volcanoes might help _____.
| A．warn people to protect the environment |
| B．support the study of Earth’s future climate |
| C．tell the future eruption time of the volcanoes |
| D．reduce the possibility of the volcanoes’ eruptions |
In which part of a newspaper could we find this text?

An 80-year-old man was sitting on the sofa in his house along with his 45-year-old son. Suddenly a crow (乌鸦) landed on their window. The father asked his son, “What is that?” The son replied, “That is a crow.” After a few minutes, the father asked his son for the second time, “What is this?”
The son said, “Father, I told you just now. It’s a crow.” After a little while, the father asked his son the same question for the third time, “What is this?” This time, the son said to his father in a low and cold tone, “It’s a crow, a crow.” After a moment, the father yet again asked his son for the fourth time, “What is this?” This time his son shouted at his father, “Why do you keep asking me the same question again and again? I have told you already, ‘IT IS A CROW’. Are you not able to understand this?” A minute later the father went to his room and came back with a diary, which he had kept since his son was born.

Every year there are hundreds of earthquakes in different parts of the world. In September, 1923, Tokyo and Yokohama were both destroyed by an earthquake and the fires that followed it. They had to be completely rebuilt. One of the most serious earthquakes was in China’s Shanxi province in 1556. It killed almost one million people.
We measure an earthquake’s strength on the Richter Scale. The Richter Scale was introduced in 1935 in Southern California in the USA. It measures earthquakes on a scale of one to ten. Any earthquake measuring five or more is usually serious.
The Earth’s crust(地壳) is made up of rock called plates. As these plates move, they sometimes crash against each other, causing the crust to quake. In cities such as Tokyo, where small quakes happen quite often, many modern buildings are designed to be flexible so when the Earth moves, they move with it.
Earthquakes can also break up gas and oil pipes. This can cause fires to break out, which can do as much damage as the earthquake itself. Another effect of earthquakes is tsunamis. These are huge waves created by earthquakes beneath the sea. They can be many meters high and cause great damage to coastal towns and cities, China, Japan, Russia and the USA have the highest occurrence(发生) of earthquakes in the world.The passage is mainly about .
