CUR, from the Latin verb curare, means basically "care for." Our verb cure comes from this root, as do manicure("care of the hands") and pedicure ("care of the feet.").

curative. Having to do with curing diseases.

例句：As soon as the antibiotic entered his system, he imagined he could begin to feel its curative effects.

一旦抗生素进入他的(身体)系统，他想象他可以开始感受到它的治疗效果。

Medical researchers are finding curative substances in places that surprise them. Folklore has led to some "new" cures of old diseases, and natural substances never before tired have often proved effective. Quinine, which comes from a tree in the Andes, was the original drug for malaria; aspirin's main ingredient came from willow bark; and Taxol, a drug used in treating several cancers, was originally extracted from the bark of a yew(紫衫) tree. The curative properties of these natural drugs are today duplicated in the laboratory.

curator. Someone in charge of something where things are on exhibit, such as collection, a museum, or a zoo.

例句：In recent decades, zoo curators have tried to make the animals' surroundings more and more like their natural homes.

近几十年来，动物园园长一直试图让动物的生存环境越来越像自然家园。

In a good-sized art museum, each curator is generally responsible for a single department or collection: European painting, Asian sculpture, American Art, and so on. Curatorial duties include acquiring new artwork, caring for and repairing objects already owned, discovering frauds and counterfeits, lending artworks to other museums, and mounting exhibitions of everything from Greek sculpture to 20th-century clothing.

procure. To get possession of; obtain. 

例句：Investigators were looking into the question of how the governor had procured such a huge loan at such a favorable rate.

调查人员正在调查州长如何以如此优惠的价格得到如此巨额的贷款。

While procure has the general meaning of "obtain," it usually implies that some effort is required. It may also suggest getting something through a formal set of procedures. In many business offices, a particular person is responsible for procuring supplies, and government agencies have formal procurement policies. When teenagers use an older friend to procure the wrong kind of supplies for their parties, they often risk getting into trouble.

sinecure. A job or position requiring little work but usually providing some income.

例句：The job of Dean of Students at any college is no sinecure; the hours can be long and the work draining.

任何一所大学的学生院长的工作都不是闲职; 时间可能很长，并且工作令人筋疲力竭。

Sinecure contains the Latin word sine, "without," and thus means "without care." In some countries, the government in power may be free to award sinecure positions to their valued supporters; in the other countries, this would be regarded as corruption. The positions occupied by British royalty are called sinecures by some people, who claim they enjoy their enormous wealth in return for nothing at all. But their many supporters point to the amount of public-service, charitable, and ceremonial work they perform, not to mention the effort they put into promoting Britain to the world.

PERI, in both Latin and Greek, means "around." A period is often a span of time that keeps coming around regularly, day after day or year after year. With a periscope, you can see around corners. Peristalsis is the process that moves food around the intestines; without it, digestion would grind to a halt.

perimeter. The boundary of distance around a body or figure.

例句：In a medieval siege, an army would surround the perimeter of a city's high walls, denying the population any food from outside as it assaulted the walls with catapults and battering rams.

在中世纪的围攻中，一支军队会包围外部高墙，从外面断绝所有实物，同时用弩炮和猛烈撞击攻打城墙。

The perimeter of a prison is ringed with high walls and watchtowers, and the entire perimeter of Australia is bounded by water. In geometry, you may be asked to calculate the perimeter of various geometrical shapes. In basketball, the perimeter is the area beyond the free-throw circle; a "perimeter player" tends to stay outside that circle. Try not to confuse this word with parameter, which usually means a rule or limit that controls what something is or how it can be done.

periodontal. Concerning or affecting the tissues around the teeth.

例句：Years of bad living had filled his teeth with cavities, but it was periodontal disease that finished them off.

多年的恶劣生活使他的牙齿满是龋洞，但是使牙齿完全脱落的是牙周疾病。

In dentistry, cavities are important but they aren't the whole story; what happens to your gums is every bit as vital to your dental health. When you don't floss regularly to keep plaque from forming on your teeth and gums, the gums will slowly deteriorate. Dentists called periodontists specialize in the treatment of periodontal problems, and when the gums have broken down to the point where they can't hold the teeth in place a periodontist may need to provide dental implants, a costly and unpleasant process. But even a periodontist can't keep your gums healthy; that job is up to you.

peripatetic. (1) Having to do with talking. (2) Moving or traveling from place to place.

例句：She spent her early adult years as a peripatetic musician, traveling from one engagement to another.

她作为巡回演奏的音乐家度过了刚成年的那几年，四处旅行，四处演奏。(这句话真难翻译... 我这种水平只能翻译成这样了... 求大佬指点)

The philosopher Aristotle had his school at the Lyceum gymnasium in Athens. The Lyceum may have resembled the Parthenon in being surrounded by a row of columns, or colonnade, which the Greeks would have called a peripatoi. Aristotle was also said to have paced slowly while teaching, and the Greek word for “pacing" was peripatos. And finally, peripatos meant simply "discussion." Whatever the source of the word, Aristotle and his followers became known as the Peripatetics, and the "pacing" sense led to peripatetic's English meaning of traveling or moving about. Johnny Appleseed is a good example of a peripatetic soul, and peripatetic executives and salespeople today stare into their laptop computers while endlessly flying from city to city.

peripheral. (1) Having to do with the outer edges, especially of the field of vision. (2) Secondary or supplemental.

例句：Like most good fourth-grade teachers, he had excellent peripheral vision, and the kids were convinced that he had eyes in the back of his head.

像大多数优秀的四年级教师一样，他有优秀的周围视野，孩子们相信他的后脑勺有眼睛。

Your peripheral vision is the outer area of your field of vision, where you can still detect movement and shapes. It can be very valuable when, for instance, you're driving into Chicago at rush hour, especially when switching lanes. When people call an issue in a discussion peripheral, they mean that it's not of primary importance, and they're probably suggesting that everyone get back to the main topic. Peripheral is now also a noun: computer peripherals are the added components--printers, webcams, microphones, etc.---that increase a computer's capacities.
