An electronic calculator is a smal, portable electronic device used to perform both arithmetic operations and complex mathematical operations. The first solid electronic calculator was created in the 1960 s, building on the extensive history of tools such as the abacus (developed around 2000 BC), and the mechanical calculator (developed in the 17 century AD). It was developed in paralel with the analog computers of the day. In addition to general purpose of calculators, there are those designed for specific markets, for example, there are scientific calculators which include trigonometric and statistical calculations. Some calculators even have the ability to do computer algebra. Graphing calculators can be used to graph functions defined on the real line, or higher dimensional Euclidean space. According to the text, what is the usage of calculator?

• To play music

• To count numbers

• To check time

• To make notes about numbers

A laptop is a kind of computer unit which has the same function as a PC (Personal Computer), but it’s smaler, lighter and of different sizes. Nowadays, most people choose laptops for several reasons. A laptop is a portable device. This portability is very helpful for our work, study and other activities. We do not need complicated cable instalations to activate a laptop. With a laptop, we can do our work anytime and anywhere. Moreover, a laptop alows us to access the internet in public places which provide free access caled hot spot areas. Some people like to use this facility to carry out their tasks. Fina ly, a laptop consumes energy more efficiently than a PC does. This device uses a rechargeable battery as a source of electric energy. So, if we prefer using a laptop, it means that we support the government program to save energy. That’s why a laptop has become very popular recently.

High in dense bamboo forests in the misty, rainy mountains of southwestern China lives one of the world's rarest mammals: the giant panda.

Pandas eat almost nothing but bamboo shoots and leaves. Occasionally they eat other vegetation, fish, or small animals, but bamboo accounts for 99 percent of their diets. They digest only about a fifth of what they eat. Overall, bamboo is not very nutritious. To stay healthy, they have to eat a lot—up to 15 percent of their body weight in 12 hours—so they eat fast.

Pandas' molars are very broad and flat. The shape of the teeth helps the animals crush the bamboo shoots, leaves, and stem that they eat. They can chomp on bamboo up to one-and-a-half inches thick. A panda should have at least two bamboo species where it lives, or it will starve. A scarcity in bamboo threatens the already limited panda population.
