21、There is much to see Australia that you can’t see easily in its natural setting anywhere else. A visit to Australia would not be complete without taking the chance to see some of these animals in their natural environment.
Bandicoot
There are several species of Bandicoot around Australia, and although occasionally they can be seen during the day, they are generally nocturnal. Bandicoots are small creatures only about the size of a rat and eat small insects and plants. Several of the Bandicoots around Australia include the Eastern Barred Bandicoot, which is now rare around Australia and the Southern Brown Bandicoot found in eastern and western parts of Australia.
Koala
Koalas are small bears like creatures that live along the east coast of Australia, with their habitat amongst the famous Eucalyptus trees. However, koalas only like to eat a small percentage of the Eucalyptus trees found around Australia. Koalas have hard black noses, with sharp claws and a thick furry coat and can grow to a weight of about 10kg. most of their time is spent asleep in the trees, which is the best place to see a koala.
Dingo
Dingoes are found in various areas across Australia, and unlike domestic dogs do not bark. Instead, the Dingo makes a howling sound that is very particular. Dingoes generally eat mice, rabbits and rats, although sometimes they can also attack livestock(家畜) when hungry.
Frilled Lizard
The Frilled Lizard is found in the eastern and northern parts of Australia, living within the bush. The Frilled Lizard frill normally hangs around its neck, and is made out of a flap of skin. When threatened, the Frilled Lizard will raise its frill making it seen more dangerous.
【1】When in danger the Frilled Lizard will raise its frill in order to .

22、 Though not as mainstream as devices like smartphones and fitness trackers, more companies are now experimenting with the concept of connected garments. Among the pioneers is London-based CuteCircuit, whose latest creation is the “Sound Shirt”, which allows deaf people to “feel” live music by transforming the tunes into touch sensations in real time.
The fashionable jacket achieves the incredible function using software that changes the music into data and wirelessly sends it to the 16-micro motors fitted inside the clothing’s fabric. The devices shake in sync（同步）to the intensity(强度）of the music being played, allowing the wearer to feel each instrument individually. The series of touch-like sensations across the wearer’s body enables them to feel the entire works, resulting in a fully amazing musical experience.
To ensure the shirt is comfortable, the designers chose to leave out wires and instead wove conductive textiles(传导纺织品) into the garment’s fabric. Francesca Rosella, co-founder, and chief creative officer of CuteCircuit, explains, “There are no wires inside, so we’re only using smart fabrics—we have a combination of microelectronics and very thin, flexible and conductive fabrics. All these little electronic motors are connected with these conductive fabrics so that the garment is soft and stretchable.”
CuteCircuit, which has been testing the Sound Shirt for three years, expects to make it available to the general public shortly. Priced at $3,673(3,000 pounds), the smart jacket will not be cheap. However, twin sisters Hermon and Heroda Berhane, who lost their hearing at a young age, believe the hi-tech garment is a worthwhile investment, especially for deaf people with a passion for dancing. “It’s almost like feeling the depth of the music,” says Hermon. “It just feels as though we can move along with it.” Heroda agrees, adding, “I think it could definitely change our lives.”
【1】What is “sound shirt” meant for?
A.Deaf people. B.Poor people C.Students. D.Musicians.
【2】Which aspect of the “Sound Shirt” is mainly talked about in paragraph 2?
A.Special materials. B.Powerful function.
C.Working principle. D.Fashionable design.
【3】How did the designers manage to keep the shirt comfortable?
A.By using wires. B.By using smart fabrics.
C.By avoiding electronic motors. D.By making the shirt very thin.
【4】Why did the writer mention twin sisters Hermon and Heroda Berhane?
A.To persuade us to learn from them.
B.To get the public to know them better .
C.To state the smart jacket is affordable.
D.To prove the smart jacket enjoys promising future.
23、The moon, which has experienced a distinct and complex geological history, presents a striking appearance. The moon may be divided into two major terrains: the Maria (dark lowlands) and the Terrace (bright highlands). The contrast in the reflectivity (he capability of reflecting light) of these two terrains suggested to many early observers that the two terrains might have different compositions, and this assumption was confirmed by missions to the moon such as Surveyor and Apollo.
One of the most obvious differences between the terrains is the smoothness of the Maria in contrast to the roughness of the highlands. This roughness is mostly caused by the abundance of craters: the highlands are completely covered by large craters, while the craters of the Maria tend to be much smaller. It is now known that the vast majority of the moon’s craters were formed by the impact of solid bodies with the lunar surface.
Most of the near side of the moon was thoroughly mapped and studied from telescopic pictures years before the age of space exploration. Earth-based telescopes can recognize objects as small as a few hundred meters on the lunar surface. Close observation of craters, combined with the way the moon diffusely reflects sunlight, led to the understanding that the moon is covered by a surface layer with strange, winding marks. Although various land forms were discovered, the majority of astronomers’ attention was fixed on craters and their origins.
Astronomers have known for a fairly long time that the shape of craters changes as they increase in size. Small craters have relatively simple shapes. They have round-edged tops that are raised above the surrounding terrain, smooth, bowl-shaped insides, and depths that are about one-sixth their diameters. The complexity of shape increases for larger craters.
【1】What does the text mainly discuss?
A．The aim of the Surveyor and Apollo space missions.
B．Characteristics of the major terrains of the moon.
C．The origin of the moon’s craters.
D．Techniques used to discover the moon’s land forms.
【2】Why are the Surveyor and Apollo missions mentioned?
A．To confirm earlier theories about the moon’s surface.
B．To reveal that previous ideas about the moon’s craters were unreasonable.
C．To provide detailed information about the moon’s surface.
D．To identify how the moon’s craters were made.
【3】The author mentions “strange, winding marks” in paragraph 3 as an example of ________.
A．an aspect of the lunar surface discovered through lunar missions
B．a characteristic of large craters
C．a discovery made through the use of earth-based telescopes
D．features that astronomers observed to be common to the earth and the moon
【4】The last paragraph probably continues with ________.
A．some difference in the ways small and large craters were formed
B．the different shapes small craters can have
C．the reasons craters are difficult to study
D．the description of some features of large craters
24、Scientists have built a bacterium that contains the minimal（最小的）genetic ingredients needed for free living. This bacterium's entire set of genetic blueprints, its genome（基因组）, consists of only 473 genes, including 149 whose precise biological function is unknown. The newly-created bacterium contains a minimalist version of the genome of Mycoplasma mycoides （丝状支原体）.Mycoplasmas have already had some of the smallest known genomes.
In 2010, researchers at the J. Craig Venter Institute in La Jolla, Calif, created the entire genome of M. mycoides and popped it into a cell of a different species, Mycoplasma capricolum （山羊支原体）, creating what some people called the first synthetic（合成的）organism. The new work strips the M.mycoides genome down to its essential elements before transplanting it to the M. capricolum shell, producing a minimal bacterium called syn3.0. Researchers hope syn3.0's genome will teach them more about the basics of biology. Such minimal genome bacteria also may be helpful to build custom-made microbes（微生物）for producing drugs or chemicals.
J. Craig Venter, founder of the nonprofit institute, and a team of researchers there led by Clyde Hutchison III and Daniel Gibson initially set out to design an organism based on a core set of about 300 genes that researchers guessed a microbe would need to survive on its own. But when the researchers tried to bring their computer creations to life, "every one of our designs failed, "Venter said. About 32 percent of the genetic ingredients ultimately needed to cook up even a simple organism were left out of the initial recipe because the researchers didn't know what the genes did and didn't understand their importance. Once those genes were mixed back, the bacteria sprung to life.
"I think we're showing how complex life is in even the simplest of organisms, "Venter said. "These findings are very humbling "because they show that researchers still don't fully understand even the minimal requirements for life. Other researchers have attempted to make minimal genomes by stripping away one gene at a time. But the Venter group built their lean microbe from the ground up. Drew Endy, a synthetic biologist at Stanford University, is among several scientists applauding the approach. "Only when you try to build something do you find out what's truly required. Too often in biology we end up with only data or a just-so story ."Endy said in an e-mail.
At first, the genome didn't work. Some genes that appeared to be nonessential for life are really requirements, the researchers discovered. Those genes tended to have redundant functions with another gene. Researchers could remove one of those genes, but not both at the same time, just as knocking out one engine on a twin-engine jet will keep the plane airborne, but disabling both engines will lead to a crash, says Gibson.

A．Controversial.
B．Unexpected.
C．Unnecessary.
D．Contradictory.
