understanding of how many stars there are in the galaxy than how many species there are on Earth？ Their estimates of global species diversity vary from 2 to 100 million species. Most people agree on an estimate of somewhere near 10 million and yet only 1.75 million have actually been named. Current knowledge of species diversity is limited. This problem becomes more serious because there is a lack of a central database or list of the world’s species.
New species are still being discovered — even new birds and mammals(哺乳动物). On average, about three new species of birds are found each year, and since 1990, 10 new species of monkeys have been discovered. Other groups are still far from being completely described: an estimated 40 percent of freshwater fishes in South America have not yet been classified.
Scientists were startled in 1980 by the discovery of a huge diversity of insects in tropical forests. In one study of just 19 trees in Panama, 960 new species of beetles were discovered.
As scientists begin investigating other little-known ecosystem, like the soil and the deep sea, “surprising” discoveries of species become commonplace. There is nothing strange about this, though, since as many as a million undescribed species are believed to live in the deep sea. And one gram of a small-sized piece of land might hold 90 million bacteria(菌类) and other microbes(微生物). How many species these communities contain is still anyone’s guess.
16. Which of the following is true？
A) Scientists have a sound knowledge about the diversity of species
B) Scientists don’t know much about the number of stars in the galaxy
C) Scientists show more interest in stars in the galaxy than in species on Earth
D) Scientists don’t agree on the number of species in the world
17. How many species are there on Earth according to most scientists？
A) About 2 million
B) About 10 million
C) About 100 million
D) About 1.75 million
18. In which of the following groups is the discovery of new species not mentioned in
the passage？
A) Birds
B) Monkeys
C) Trees
D) Freshwater fish
19. What can you learn from the passage？
A) The soil and the deep sea belong to communities that haven’t been fully explored
B) It is surprising news wherever new species are discovered in the deep sea
C) About 90 million species are believed to live in the deep sea
D) A million species in the deep sea have been discovered and named
20. Which of the following best reveals the main idea of the passage？
A) Surprising discoveries of new species are commonplace
B) The mystery of the deep sea and the soil remains to be uncovered
C) Knowledge of global species diversity is still limited
D) Estimates of global species diversity vary among scientists

Deer leave the high ground and come down from the mountains before a storm.If you see this, you can be sure that there will be a storm within two days.When you see large numbers of sea crabs on a sandy beach, it is time to leave.A change in air pressure over the water warns the crabs that a storm is coming.To escape the stormy sea pounding the shore, they leave the water and seek shelter on land.
Birds are especially good weather indicators because they also show the effect of a pressure drop in many ways.For example, some birds become easily annoyed and will fight over a piece of bread.Other birds sing just before a storm.It seems they know they won't get another chance for an hour or two.Birds also seek shelter before a storm.You will sometimes see birds resting in trees or staying closely together on a wire near a building.This is a good storm signal.
Seabirds sit out a storm on land.Anytime you see seagulls sitting on the ground in large groups, reluctant to fly, it is not a very good day to go sailing.It is unusual to see large groups of birds flying overhead in the summertime.Watch for other weather signs if you see this.You should also stay alert if you see migrating birds flying in the wrong direction.These birds may be flying ahead of a storm.And if you can't see a bird anywhere, look out! They may have flown to a different place because a violent storm is coming in their direction.
1.What's the main idea of the passage？
A.How to pay close attention to important clues in nature.

2.When a storm is surely coming in two days, ________.
A.some birds become easily annoyed and fight with each other
B.deer leave the high ground and come down from the mountains
C.large number of sea crabs move on a sandy beach
D.field mice come out of their holes and run around

根据下列文章,请回答 31～35 题。
Renewable Energy Sources
Today petroleum provides around 40% of the world's energy needs, mostly fuelling automobiles. Coal is still used, mostly in power stations, to cover one-quarter of our energy needs, but it is the least efficient, unhealthiest and most environmentally damaging fossil fuel. Natural gas reserves could plug some of the gap from oil, but reserves of that will not last into the 22nd century either. Most experts predict we will exhaust easily accessible reserves within 50 years. We could fast reach an energy crisis. We need to rapidly develop sustainable solutions to fuel our future. Less-polluting renewable energy sources offer a more practical long-term energy solution. They may benefit the world's poor too. "Renewable" refers to the fact that these resources are not used faster than they can be replaced.
The Chinese and Romans used watermills over 2000 years ago. But the first hydroelectric (水电的) dam was built in England in 1870. Hydroelectric power is now the most common form. of renewable energy, supplying around 20% of world electricity. China's Three Gorges Dam, which has just been completed, is the largest ever. At five times the size of the US's Hoover Dam, its 26 turbines (涡轮机) will generate the equivalent energy of 18 coal-fired power stations. It will satisfy 3% of China's entire electricity demand. Surprisingly, some argue that hydroelectric dams significantly contribute greenhouse gases.
In 2003, the first commercial power station to harness tidal currents (潮汐发电) in the open sea opened in Norway. It is designed like windmills, but others take the form. of turbines.
As prices fall, wind power has become the fastest growing type of electricity generation - quadrupling (变成四倍) worldwide between 1999"and 2005. Modern wind farms consist of turbines that generate electricity. Though it will be more expensive, there is more than enough wind to provide the world's entire energy needs. Wind farms come in onshore and offshore forms. They can often end up at spots of natural beauty, and are often unpopular with residents. And turbines are not totally benign (无害的) - they can interfere with radar and leave a significant ecological footprint, altering climate and killing sea birds. Migrating birds may have more luck avoiding them. Scotland is building Europe's largest wind farm, which will power 200,000 homes. The UK's goal is to generate one-fifth of power from renewable sources, mainly wind, by 2020. But this may cause problems, because wind is unreliable.
第 31 题 According to the passage, the most popular form. of renewable energy in the world is_________
A．hydroelectric power.
B．solar energy.
C．wind powers
D．tidal power.

Mammals have a number of features that distinguish them from the reptiles from which they developed. They are warm blooded; that is, they have a system of temperature control that keeps the body at a constant temperature. Mammals have a set of teeth of different shapes that serve different functions such as cutting, gouging, and grinding. Young mammals spend their earliest days of development shielded within the mother's body and are then born alive, rather than hatching from eggs. In addition, after birth they are nourished by milk provided by the mother's mammary glands. The enforced association between mother and infant provides an opportunity for learning that does not exist for those kinds of creatures that are hatched from eggs long after their parents have departed from the scene. Young mammals play -- something that amphibians and reptiles never do -- which provides additional learning opportunities.
The foregoing list leaves little doubt that we are mammals. There are, of course, a great many kinds of mammals, most of which developed after the great extinction of dinosaurs and other reptiles about 65 million years ago that opened opportunities for the few small mammals that were already in existence. One of the groups of mammals that resulted was a biological order called Primates which includes monkeys, apes, humans, and some smaller creatures familiar only to ardent zoogoers. Primates share a number of behavioral features that have played important roles in their evolutionary development. Most primates are arboreal; that is, they spend their lives in and among trees. Their tree-climbing and tree-dwelling habits impose needs that are reflected in primate anatomy. Although diet varies from species to species, many primates are largely vegetarian. But they can eat and digest meat, and some species vary their diets of leaves, shoots, and fruits by eating insects, birds' eggs, and even small animals. Primates are hand-feeders, depending on their hands both to collect food and to get it into their mouths. Perhaps the most important feature of their behavior. is that primates are social animals. Their genetics, habits, and even their survival are geared to living in groups. Although human beings have come to have a way of life very different from that of typical primates, the basic primate adaptation provided prehumans with capabilities that allowed them to become culture？ builders.
The anatomical features that separate primates from other kinds of animals relate clearly to the way primates behave.
Where do you think is the passage from？
A．Newspaper.
B．Gazette.
C．Journal.
D．Science magazine.
