Do you suppose Darwin, one of the greatest scientists of all time, really did foolish experiments? Or did he do experiments that were so simple and basic that other people just thought they were foolish?
Sometimes, people think they already know the answer to a question or the solution to a problem. Sometimes, they really do know an answer or a solution, but without thinking they are important.
Charles Darwin didn’t settle for(满足于)just thinking he knew something. And, he believed all things could be important however simple they seemed to be.
Suppose you drop sheets of paper that are of exactly the same size and shape. If you drop them at the same time in the same place, they will fall in the same way. Now make one of the sheets of paper into a tight little ball and let it drop along with the other sheets. What happens? You have done an experiment that is so simple that you might think it couldn’t be worth anything.
But this simple experiment is important. It explains part of our present-day understandings of physics, ideas that were worked out long ago by Galileo and Newton. And these understandings set aside some of ancient Greek physics.
Scientists sometimes stop to look at very simple things and to think very hard about them. Even the simplest idea, which we might think is foolish, can shake the foundations of science.
1. The passage tells us that Charles Darwin .
A. was a great English scientist
B. always liked doing the experiments that others thought difficult
C. thought even the simplest thing was important
D. didn’t get well with others
2. The underlined phrase “set aside” most probably means .
A. throw away B. store up
C. put to use D. realize
3. The author of the passage tries to .
A. convince us that Charles Darwin, Galileo and Newton are the greatest scientists in the world
B. draw the conclusion that basic sciences are simple things
C. prove that two sheets of paper, with the same size and shape, will fall at the same speed
D. draw our attention to everyday happenings around us
4.Which of the following is TRUE?
A. Darwin really did foolish experiments.
B. According to some people Darwin did foolish experiments.
C. It is believed by all the people that things could be important though they seemed to be simple.
D. Galileo and Newton worked out ancient Greek physics.

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

高三英语单项填空简单题查看答案及解析
Since English biologist Charles Darwin published On the Origin of Species in 1859, scientists have vastly improved their knowledge of natural history. However, a lot of information is still of the speculation, and scientists can still only make educated guesses at certain things.
One subject that they guess about is why some 400 million years ago, animals in the sea developed limbs (肢) that allowed them to move onto and live on land.
Recently, an idea that occurred to the US paleontologist (古生物学家) Alfred Romer a century ago became a hot topic once again.
Romer thought that tidal (潮汐的) pools might have led to fish gaining limbs. Sea animals would have been forced into these pools by strong tides. Then, they would have been made either to adapt to their new environment close to land or die. The fittest among them grew to accomplish the transition (过渡) from sea to land.
Romer called these earliest four-footed animals “tetrapods”. Science has always thought that this was a credible theory, but only recently has there been strong enough evidence to support it.
Hannah Byrne is an oceanographer (海洋学家) at Uppsala University in Sweden. She announced at the 2018 Ocean Sciences Meeting in Oregon, US, that by using computer software, her team had managed to link Homer’s theory to places where fossil deposits (沉积物) of the earliest tetrapods were found.
According to the magazine Science, in 2014, Steven Balbus, a scientist at the University of Oxford in the UK, calculated that 400 million years ago, when the move from land to sea was achieved, tides were stronger than they are today. This is because the planet was 10 percent closer to the moon than it is now.
The creatures stranded in the pools would have been under the pressure of “survival of the fittest”, explained Mattias Green, an ocean scientist at the UK’s University of Bangor. As he told Science, “After a few days in these pools, you become food or you run out of food... the fish that had large limbs had an advantage because they could flip (翻转) themselves back in the water.”
As is often the case, however, there are others who find the theory less convincing. Cambridge University’s paleontologist Jennifer Clark, speaking to Nature magazine, seemed unconvinced. “It’s only one of many ideas for the origin of land-based tetrapods, any or all of which may have been a part of the answer,” she said.
1.Who first proposed the theory that fish might have gained limbs because of tidal pools?
A. Hannah Byrne. B. Charles Darwin.
C. Alfred Romer. D. Steven Balbus.
2.Why were tides stronger 400 million years ago than they are today according to Steven Balbus?
A. There were larger oceans. B. Earth was under greater pressure.
C. The moon gave off more energy. D. Earth was closer to the moon.
3.The underlined word “stranded” in Paragraph 8 probably means “________”.
A. trapped B. settled
C. abandoned D. found
4.What is the focus of the article?
A. The arguments over a scientific theory.
B. Some new evidence to support a previous theory.
C. The proposal of a new scientific theory.
D. A new discovery that questions a previous theory.

高三英语单项填空中等难度题查看答案及解析
You must have been troubled by when to say “I love you” because it is one of the greatest puzzles in our life.
What if you say it first and your partner doesn’t love you back? Or if they do say it but you don’t feel they mean it? Being the first to declare your love can be nerve racking(紧张)and risky and can leave you feeling as vulnerable as a turtle with no shell. But is the person who says it first really in a position of weakness? Doesn’t it pay to hold back, play it cool and wait until the other half has shown their hand fast?
A really good relationship should be about “being fair and being equal,” says psychologist Sidney Crown. “But love is seldom equal.” All relationships go through power struggles but, he says, if a love imbalance continues for years, the rot will set in. “That feeling of ‘I’ve always loved you more’ may be subverted(颠覆,破坏) for a time, but it never goes away completely and it often emerges in squabbling(大声争吵).” In love, at least, the silent, withholding type is not always the most powerful. “The strongest one in a relationship is often the person who feels confident enough to talk about their feelings,” says educational psychologist Ingrid Collins. Psychosexual therapist Paula Hall agrees. “The one with the upper hand is often the person who takes the initiative. In fact, the person who says ‘I love you’ first may also be the one who says ‘I’ m bored with you’ first.” Hall believes that much depends on how “I love you” is said and the motivation of the person saying it. “Is it said when they’re drunk? Is it said before their partner files off on holiday, and what it really means is ‘Please don’ t be unfaithful to me’ ?” By saying ‘I love you’, they are really saying ‘Do you love me?’ If so, wouldn’t it just be more honest to say that. Collins agrees that intention is everything. “It’s not what is said, but how it’s said. What it comes down to is the sincerity of the speaker.”
1. What is the main idea of this passage?
A. The importance of “I love you”
B. The meaning of “I love you”
C. The time of saying “I love you”
D. The place of saying “I love you”
2. In the first sentence the author means that _________.
A. it is easy to say “I love you”
B. it is hard to say “I love you”
C. we have many troubles in our life
D. people usually do not know when to say “I love you”
3. According to the expert, a good relationship should be _______.
A. fair and equal B. fair and kind
C. powerful and equal D. confident and fair
4. In the third paragraph, the phrase “with the upper hand” means _________.
A. being low in spirit B. having only one hand
C. being active D. being passive
