Now in New York City, USA, a rule is carried out in schools. Students can’t even bring telephones to school. Is it a good thing or not? Anxious parents say that telephones are important tool in holding New York city’s families tighter.“I worry about it,” said Elizabeth Lorris Ritter, a mother of a middle school kid. “It’s necessary in our everyday life. We have a washing machine, we have running water, and we have telephones.”Many American parents think telephones connect them to their children on buses, getting out from subways, walking through unknown places.“I have her call me when she gets out of school,” said Lindsay Walt, a schoolgirl’s mother. “Nobody in New York is going to let their child go to school without a telephone.”What about the telephone owners, the students? Most of the students said telephones were essential and the telephone was like an extra hand or foot for them.“I feel so empty,” said May Chou, 14. “There is also no way to listen to music on the way to school without my phone.

But much of the time snails don’t move at all. They’re in their shells (壳)---sleeping .Hot sun will dry out a snail’s body. So at the least sign of hot sun, a snail draws its body into its shell and closes the opening with a thin cover. Then it goes to sleep. A snail will die in a heavy rain. So whenever it rains, it goes inside its shell house and goes to sleep. A snail can sleep for as long as it needs to. It can take a short sleep. Or it can sleep for days at a time. And it spends all the winter months in its shell, asleep.In spring the snail wakes up. Its body, about three inches long, comes out offrom th e shell. When hungry, the snail looks for food. It can’t see very well. Its eyes, at the ends of the top feelers (触角)are very weak. But its sense of smell is very strong. It helps the snail to the new greens. Then the snail’s little mouth goes to work.A snail’s mouth is no longer than the point of a pin(针) . Yet it has 256,000 teeth! The teeth are so small that you can’t see them. But they do their work. If you put a snail in a hard paper box, it will eat its way out. And if a snail wears out its teeth, it will grow new ones.Mostly, a snail looks for food at night. But on cloudy days it eats in the daytime. It eats all day long. A snail can go on eating for hours and never feel full.16. A snail .A. moves more slowly in the daytimeB. has thousands of feetC. sleeps much of the time17. In the sentence “A snail draws its body into its shell”, the word “draw” means_________.A. to make with a penB. to keep away fromC. to pull18.

In winter the snail doesn’t eat or moveC. The snail’s teeth can’t be worn out.( E )Firstly, let’s learn the contactor. A contactor is an electrically controlled switch used for switching a power circuit. Generally speaking, a contactor is activated by a control input which is a lower voltage / current than that which the contactor is switching. Contactors come in many forms with varying capacities and features.Contactors vary from having a breaking current of several amps and 110 volts to thousands of amps and many kilo-volts. The physical size of contactors differs from a few inches to the size of a small car.Then let’s know the purpose of contactor. Usually, contactors are used to control electric motors, lighting, heating, capacitor banks and other electrical loads.A nd now let’s see what a contractor consists of. We can say: a contactor consists of 3 different systems: contact system, electromagnet system and arc control system.So do you know their function? In a general way, the contact system is the current carrying part of the contactor. This includes power contacts, auxiliary contacts, and contact springs. The electromagnet system provides the driving force to close the contacts.FuseMaybe you have already known that a fuse is the easiest and efficient protective electrical apparatus and it is designed for short circuit protection in many cases. Always we use FU to stand for fuse.21. A contactor is an electrically controlled switch used for switching a ____circuit.A. noneB. secondaryC. primaryD. power22. Contactors are used to control electric____, lighting, heating, capacitorbanks and other electrical loads.A. noneB. bothC. generatorsD. motors23. A contactor consists of 3 systems: contact system, ____ and arc control system.A. toughB. strongC. electromagneticD. it does not mention24. The contact system is the ____ carrying part of the contactorA. goldB. resistanceC. currentD. voltage25. Always we use FU to stand for ____.A. inductorB. fuseC. resistorD. capacitor( F )Multi-meter is a multi-functional, multi-range, portable electronic instrument. It can be used to measure many physical quantities such as the current and voltage of DC and AC, as well as resistance, audio level and the multiple of DC magnification of the transistor, and so on. Multi-meter is composed of the head, measuring line, switch and testing pen, etc. The head is used to indicate the measured values; measuring line is used to convert various measured current to small DC current or voltage suitable for the head measurement; change-over switch is to realize different choices of measuring lines and different range to meet specific requirement.The multi-meter can be divided into analogue and digital multi-meter. Thecore, using indicators to show measured values; the digital multi-meter takes adigital voltage meter as the core, along with different converters and showsmeasured values via liquid crystal indicator.26. The multi-meter can measure current, voltage, resistance, audio leveland the multiple of DC magnification of____.A. resistorB. capacitorC. transistorD. inductor27.
