Names are different all over the world. In Jenny's class, Jenny must learn the names of students from all over the world. This is very difficult because the names are very different.
In the United States, most people have a first name, a middle name, and a last name. Parents, choose the first and middle names for their baby. There are names for boys 'and names for girls. For example, John, Peter, Tom, and Mike are all names for boys. Elizabeth, Betty, Susan, and Mary are all names for girls, The last name is the family name. Usually it is the father's family name. In a family, the mother, the father, and the children usually have the same last name.
Sometimes a person has a nickname (绰号) , too: A nickname is a special name. It is not a person's real name. Abraham Lincoln's nickname was "Honest Abe". An honest person always tells the truth, and Abe is short for Abraham. Because he was an honest person, his nickname was "Honest Abe". Pele (贝利) is a nickname, too. The football player's real name is Edison Arantes de Nascimento, but everyone calls him Pele. Do you have a nickname?
Names are different all over the world. They can be long or short, but they are always very important.

A.It is very interesting to have a name.
B.It is very easy to be remembered.

根据下面内容,回答题:
Gold used in jewelry is mixed with harder metals to add strength and durability. The metals added can also be used to change gold" s color, giving it a fashionable rose or white tint, or to lighten or darken the natural yellow, tone of pure gold.Mixtures like these, of less costly metals with more valuable ones, are called alloys. Copper and silver are the most common metals mixed with gold to make yellow gold jewelry. White gold is usually made with an alloy of gold and nickel.
The measure of gold" s purity is called a karat. The higher the karat rating,the higher the amount of pure gold: 24 karat is pure gold,18 karat is 75% pure gold,14 karat is 58.5% pure gold, and 9 karat is 37.5% pure gold. All other things being equal ,the higher the percentage of pure gold used in the alloy,the more valuable and expensive the jewelry wll be.
Gold jewelry pieces are usually stamped with a marking to identify the karat amount. While gold that is 24K is too soft for jewelry,18K,14K and 9K gold are all appropriate for jewelry, and they all make pieces that look great and wear beautifully.
Which of the following statements best.captures the main idea of this passage? 查看材料
A.Although gold is very valuable,it is also very expensive.
B.Gold jewelry is stamped with its karat ,weight.
C.Gold jewelry is made using alloys.
D.Colored gold is more valuable than white gold.

2. Kin Recognition (10分)
Many organisms, from sea squirts to primates, can identify their relatives. Understanding how and why they do so has prompted new thinking about the evolution of social behavior. by David W. Pfennig and Paul W. Sherman Kinship is a basic organizing principle of all societies. Humans possess elaborate means by which to identify relatives, such as using surnames and maintaining detailed genealogies.
Mechanisms for distinguishing kin also occur throughout the plant and animal kingdoms regardless of an organism’s social or mental complexity, in creatures as diverse as wildflowers and wasps. Scientists are beginning to discover that an understanding of the origin and mechanisms of kin recognition offers fresh insights into such diverse topics as how living things choose their mates, how they learn and how their immune system works.
BELDING’S GROUND SQUIRRELS live in groups in which mothers, daughters and sisters cooperate extensively. By using odors, the squirrels can distinguish familiar nestmates, who are close kin, from nonnestmates. They can also discriminate between full sisters and half sisters.

3 Self-Powered Nanotech (10分)
Nanosize machines need still tinier power plants
By Zhong Lin Wang
The watchmaker in the 1920s who devised the self-winding wristwatch was on to a great idea: mechanically harvesting energy from the wearer’s moving arm and putting it to work rewinding the watch spring.
Today we are beginning to create extremely small energy harvesters that can supply electrical power to the tiny world of nanoscale devices, where things are measured in billionths of a meter. We call these power plants nanogenerators. The ability to make power on a minuscule scale allows us to think of implantable biosensors that can continuously monitor a patient’s blood glucose level, or autonomous strain sensors for structures such as bridges, or environmental sensors for detecting toxins — all running without the need for replacement batteries. Energy sources are desperately needed for nanorobotics, microelectromechanical systems (MEMS), homeland security and even portable personal electronics. It is hard to imagine all the uses such infinitesimal generators may eventually find.
In Brief
★Nanotechnology has huge potential — but those minuscule devices will need a power source that is better than a battery.
★ Waste energy, in the form. of vibrations or even the human pulse, could provide sufficient power to run such tiny gadgets.
★ Arrays of piezoelectric nanowires could capture and transmit that waste energy to nanodevices.
★ Medical devices will likely be a major application. A pacemaker’s battery could be charged so it would not need replacing, or implanted wireless nanosensors could monitor blood glucose for diabetics.
