It is one of the greatest mysteries of nature. In case you haven’t noticed, all living things follow very definite, individual rhythms, all as regular as a clock, but what makes them regular?

Though many scientists maintain that these rhythms are the result of some outside force like gravity or radiation or both, the results of most scientific researches agree with other scientists who believe that each living thing has its own built-in biological “time clock.”

Take the mystery of migration for example. Scientists can’t really explain why many species of birds migrate in the autumn even though the temperature is still summery. The birds just seem to snub the comfortable weather that they are having. When a certain time comes, they travel south by the thousand. In spring time, they migrate northwards even though there probably is snow still covering the ground when they finally arrive. Something said “go,” and they did.

Animals that hibernate (冬眠) are obeying individual time clocks, too. When their clock indicates the time to take a winter’s nap, they do, and nothing can stop them. At a certain time in the spring, they wake up and come out regardless of the weather outside.

Plants appear to have yearly rhythms, such as the sprouting of seeds, and they also have daily rhythms. Notice sometimes that plants raise their leaves in daylight and lower them at night.

If you live along the California coast, you can easily observe a demonstration of this mysterious clock functioning regularly. There, from February to September, the highest tides occur exactly every fourteen and four-fifths days, and during these high tides, but at no other time, small silvery fish called grunions surf-ride a wave to the beach. There the female deposits her eggs in the sand and the male fertilizes them; then both hitch a wave-ride back to the sea. Exactly fourteen and four-fifths days later, never before or after, the tiny eggs hatch, and the high tide carries the new babies out to sea.

72. According to the passage, the mysterious rhythms result from ______.

A. the influence of gravity on living species

B. the effect of radiation on living species

C. the influence of a mysterious outer force on living species

D. the internal mechanism inside the living species

73. The underlined word “snub” in the third paragraph probably means ______.

A. fight   B. ignore C. symbolize   D. criticize

74. Which of the following statements is NOT TRUE?

A. Hibernating animals are obeying an internal time clock.

B. The positioning of the leaves of some plants is due to the daily rhythms.

C. The internal clock functioning is demonstrated in the reproducing habits of grunions.

D. The yearly hibernation is more because of the weather influence than the biological functioning.

75. The passage is mainly about ______.

A. the rhythms of life

B. the reasons of mysterious hibernation

C. strange behaviors of species

D. the timing for different events in the world of species

You can relax if remembering everything is not your strong suit. Recent research makes the case that being forgetful can be a strength—in fact, selective memory can even be a sign of stronger intelligence.

Traditional research on memory has focused on the advantages of remembering everything. But looking through years of recent memory data, researchers Paul Frankland and Blake Richards of the University of Toronto found that the neurobiology（神经生物学） of forgetting can be just as important to our decisionmaking as what our minds choose to remember.

“The goal of memory is not the transmission of information through time. Rather, the goal of memory is to help improve decisionmaking. As such, transience(转瞬即逝) is as important as persistence in memory systems，” their study in Neuron states.

Making intelligent decisions does not mean you need to have all the information at hand, it just means you need to hold onto the most valuable information. And that means clearing up space in your memory palace for the most uptodate information on situations. Our brains do this by generating new neurons(神经元) in our hippocampus(海马体), which have the power to overwrite existing memories that are influencing our decisionmaking.

“If you're trying to deal with the situation and your brain is constantly bringing up multiple conflicting memories, that makes it harder for you to make a wise decision，” Richards told Science Daily.

If you want to increase the number of new neurons in your brain's learning region, try exercising. Moderate aerobic exercise like jogging, power walking, and swimming have been found to increase the number of neurons making important connections in our brains.

When we forget the names of certain clients and details about old jobs, our brain is making a choice that these details do not matter. Although too much forgetfulness can be a cause for concern, the occasional lost detail can be a sign of a perfectly healthy memory system. The researchers found that our brains facilitate decisionmaking by stopping us from focusing too much on minor past details. Instead, the brain promotes generalization, helping us remember the most important gist of a conversation.

“One of the things that distinguishes an environment where you're going to want to remember stuff versus an environment where you want to forget stuff is this question of how consistent the environment is and how likely things are to come back into your life，” Richards said.

If you're an analyst who meets with a client weekly, your brain will recognize that this is a client whose name and story you need to remember. If this is someone you may never meet again, your brain will weigh that information accordingly.

These findings show us that total recall can be overrated. Our brains are working smarter when they aim to remember the right stories, not every story.
