A.VEHICLES
1.CARS
Some small "city" cars carry only two to four people, and have very little luggage space. Other types are able to carry many passengers or heavy loads. For example, family station wagons or estate cars carry from 5 to 9 people, or fewer people with lots ofluggage. A van or pickup truck is a car-like vehicle made for carrying medium sized loads; for example, goods for delivery or plumber's and builder's tools and materials. Heavy lorries are used to carry deliveries and heavy loads.
In order for a car to work, it must have fuel. The most common fuel is petrol, which is called gasoline in America. A car can also run ondiesel or ethanol. Alternative fuel vehicles use less common fuels like natural gas, wood gas or electricity. Some car-making companies have also tried building vehicles that run using hydrogen fuel cells, which do not give out any polluting exhaust gases (but making hydrogen may at first still need electricity made by a power plant that burns similar fossil fuels). In some countries, such as Brazil andSweden, a mixture of ethanol and petrol, called gasohol in Brazil and E-85 in Sweden, is used as automobile fuel.
2.AIRPLANES
An airplane or aeroplane (informally plane) is a powered fixed-wing aircraft that is propelled forward by thrust from a jet engine or propeller. Airplanes come in a variety of sizes, shapes, and wing configurations. The broad spectrum of uses for airplanes includes recreation, transportation of goods and people, military, and research.
Most airplanes are flown by a pilot on board the aircraft, but some are designed to beremotely or computer-controlled.

3.SHIP
Since the end of the age of sail[vague] a ship has been any large buoyantwatercraft. Ships are generally distinguished from boats based on size andcargo or passenger capacity. Ships are used on lakes, seas, and rivers for a variety of activities, such as the transport of people or goods, fishing,entertainment, public safety, and warfare. Historically, a "ship" was a vessel with sails rigged in a specific manner.
Ships and boats have developed alongside humanity. In armed conflict and in daily life they have become an integral part of modern commercial and military systems. Fishing boats are used by millions of fishermen throughout the world. Military forces operate vessels for combat and to transport and support forces ashore. Commercial vessels, nearly 35,000 in number, carried 7.4 billion tons of cargo in 2007.[1] Total number of ships(with IMO number) as of 2011 is about 104,304.[2]
Ships were a key in history's great explorations and scientific and technological development. Navigators such as Zheng He spread such inventions as the compass and gunpowder. Ships have been used for such purposes as colonization and the slave trade, and have served scientific, cultural, and humanitarian needs. After the 16th century, new crops that had come from and to the Americas via the European seafarers significantly contributed to the world's population growth. Maritime transport has shaped the world's economy into today's energy-intensive pattern.
B.GADGETS
The origins of the word "gadget" trace back to the 19th century. According to the Oxford English Dictionary, there is anecdotal evidence for the use of "gadget" as a placeholder name for a technical item whose precise name one can't remember since the 1850s; with Robert Brown's 1886 book Spunyarn and Spindrift, A sailor boy’s log of a voyage out and home in a China tea-clipper containing the earliest known usage in print.[2] The etymology of the word is disputed.
A widely circulated story holds that the word gadget was "invented" when Gaget, Gauthier & Cie, the company behind the repousséconstruction of the Statue of Liberty (1886), made a small-scale version of the monument and named it after their firm; however this contradicts the evidence that the word was already used before in nautical circles, and the fact that it did not become popular, at least in the USA, until after World War I.[2] Other sources cite a derivation from the French gâchette which has been applied to various pieces of a firing mechanism, or the French gagée, a small tool or accessory.
C.APPLIANCES
Appliance may refer to:
- Home appliance, household machines, using electricity or some other energy input
- In medicine and dentistry, custom-fitted appliances to an individual for the purpose of correction of a physical or dental problem such as:
- Computer appliance, a computing device with a specific function and limited configuration ability
- Software appliance, software application combined with just enough operating system (JeOS)
- Fire apparatus, a fire engine or fire truck in British English
- In film, a term for latex pieces, such as false ears or other features, used by make-up artists
Appliance (band), a British musical group
D.BUILDING
In architecture, construction, engineering, real estate development and technology the termbuilding refers to one of the following:[citation needed]
- Any human-made structure used or intended for supporting or sheltering any use or continuous occupancy, or
- An act of construction (i. e. the activity of building, see also builder)
In this article, the first usage is generally intended unless otherwise specified.
Buildings come in a wide amount of shapes and functions, and have been adapted throughout history for a wide number of factors, from building materials available, to weather conditions, to land prices, ground conditions, specific uses and aesthetic reasons.
Buildings serve several needs of society – primarily as shelter from weather and as general living space, to provide privacy, to store belongings and to comfortably live and work. A building as a shelter represents a physical division of the human habitat (a place of comfort and safety) and the outside (a place that at times may be harsh and harmful).
Ever since the first cave paintings, buildings have also become objects or canvasess of artistic expression. In recent years, interest in sustainable planning and building practices has also become part of the design process of many new buildings.
Materials technology is a relatively comprehensive discipline that begins with the production of goods from raw materials to processing of materials into the shapes and forms needed for specific applications.
Materials - metals, plastics and ceramics - typically have completely different properties, which means that the technologies involved in their production are fundamentally different. Materials technology is a constantly evolving discipline, and new materials with interesting properties lead to new applications. For example, the combination of different materials into composites gives rise to entirely new material properties. Materials Science is closely related to materials technology. Materials Science is a multidisciplinary field that connects material properties to the material’s chemical composition, micro-structure and crystal structure.
