1. 掌握本单元重点句型；2. 掌握情态动词的概念及用法语法1.情态动词can/can not , may /may not, must/must not 的基本用法。

She has been able to play it since she was five. （现在完成时）她自从五岁起就会弹琴了。
（2）用在过去时中，could经常表示能够做某事，事实上不一定去做，而was ⁄were able to则表示“过去设法做成了某事”。

七年级下册英语electrics知识点
七年级下册英语electrics知识点Electricity is the energy that powers nearly everything we use in our daily lives. From the lights that brighten our homes to the gadgets that connect us to the world, electricity plays a big role in our modern world. In order to fully understand how electricity works, it is important to have a basic knowledge of electrics. In this article, we will cover some of the key concepts that you need to know about electrics.What is Electrics?Electrics is a branch of physics that deals with the study of electrical phenomena and the behavior of electrons. Essentially, electrics is concerned with the way that electricity moves through different materials.Electrons are tiny particles that have a negative electrical charge. When electrons move from one place to another, they create electricity. In order for electricity to flow, there needs to be a source of electrons and a path for them to move through, called a circuit.Electric CircuitsA circuit is a path that allows electricity to flow from a power source, through wires, and into a device that uses the electricity. There are two types of circuits: series circuits and parallel circuits.In a series circuit, the components are connected in a single path so that the current flows through each component in turn. If one component fails, the whole circuit will fail.In a parallel circuit, the components are connected in multiple paths, so that the current can flow through each component independently. If one component fails, the other components will still work.Electric CurrentElectric current is the flow of electric charge through a conductor. It is measured in amperes (amps). The direction of the current is the direction in which the positive charges flow.Electric VoltageElectric voltage is the difference in electrical potential energy between two points in a circuit. It is measured in volts (V). Voltage is what causes the electric current to flow through a circuit.Electric ResistanceElectric resistance is the measure of how difficult it is for an electric current to flow through a material. It is measured in ohms (Ω). Different materials have different resistance levels, and this affects how much current can flow through them.Electric PowerElectric power is the rate at which electrical energy is transformed into other forms of energy, such as heat or light. It is measured in watts (W). The power of an electrical device is a measure of how much energy it uses or produces over a given period of time.ConclusionThese are some of the key concepts that you need to know about electrics. By understanding the basics of electrics, you will be able tobetter understand how electricity works and how it powers our modern world. Whether you are interested in becoming an electrician, or you simply want to better understand how your electronics work, having a basic knowledge of electrics is essential.。
