Earl Grey tea
伯爵红茶
Earl Grey tea is a tea blend which has been flavoured with the addition of oil of bergamot. Traditionally, "Earl Grey" was made from black teas, but tea companies have since begun to offer Earl Grey in other varieties as well, such as green or oolong.
Birdie
小鸟球
Birdie means scoring one under par (−1). This expression was coined in 1899, at the Atlantic City Country Club in Northfield, New Jersey. According to a story that has been passed down, one day in 1899, three golfers, George Crump (who later built Pine Valley, about 45 miles away), William Poultney Smith (founding member of Pine Valley), and his brother Ab Smith, were playing together when Crump hit his second shot only inches from the cup on a par-four hole after his first shot had struck a bird in flight. Simultaneously, the Smith brothers exclaimed that Crump's shot was "a bird." Crump's short putt left him one-under-par for the hole, and from that day, the three of them referred to such a score as a "birdie." In short order, the entire membership of the club began using the term. As the Atlantic City Country Club, being a resort, had many out-of-town visitors, the expression spread and caught the fancy of all American golfers.
Braided fishing line
一种老式的鱼线
Braided line was one of the earliest types of fishing line, and in its modern incarnations it is still very popular in some situations because of its high knot strength, lack of stretch, and great overall power in relation to its diameter. Braids were originally made from natural fibers such as cotton and linen, but natural fiber braids (with the very rare exception of braided silk) have long since been replaced by braided or woven fibers of a man-made materials like Dacron, Spectra or micro-dyneema into a strand of line. Braided fishing lines have good resistance to abrasion, which is very important when fishing on rocky and similar terrains, where sharp objects can easily cut other fishing lines. Their actual breaking strength will commonly well exceed their pound-test rating.
Optical fiber
光导纤维
An optical fiber or optical fibre is a flexible, transparent fiber made by drawing glass (silica) or plastic to a diameter slightly thicker than that of a human hair. Optical fibers are used most often as a means to transmit light between the two ends of the fiber and find wide usage in fiber-optic communications, where they permit transmission over longer distances and at higher bandwidths (data rates) than wire cables. Fibers are used instead of metal wires because signals travel along them with lesser amounts of loss; in addition, fibers are also immune to electromagnetic interference, a problem from which metal wires suffer excessively. Fibers are also used for illumination, and are wrapped in bundles so that they may be used to carry images, thus allowing viewing in confined spaces, as in the case of a fiberscope. Specially designed fibers are also used for a variety of other applications, some of them being fiber optic sensors and fiber lasers.
Gaff
捕鱼（钓鱼）的时候，把鱼勾上来的那个手杆
In fishing, a gaff is a pole with a sharp hook on the end that is used to stab a large fish and then lift the fish into the boat or onto shore. Ideally, the hook is placed under the backbone. Gaffs are used when the weight of the fish exceeds the breaking point of the fishing line or the fishing pole. A gaff cannot be used if it is intended to release the fish unharmed after capture, unless the fish is skilfully gaffed in the lip, jaw, or lower gill using a thin gaff hook.
