英语作文 篇1

sleep is very ancient. in the electroencephalographic sense we share it with all the primates and almost all the other mammals and birds: it may extend back as far as the reptiles.

there is some evidence that the two types of sleep， dreaming and dreamless， depend on the life-style of the animal， and that predators are statistically much more likely to dream than prey， which are in turn much more likely to experience dreamless sleep. in dream sleep， the animal is powerfully immobilized and remarkably unresponsive to external stimuli. dreamless sleep is much shallower， and we have all witnessed cats or dogs cocking their ears to a sound when apparently fast asleep. the fact that deep dream sleep is rare among pray today seems clearly to be a product of natural selection， and it makes sense that today， when sleep is highly evolved， the stupid animals are less frequently immobilized by deep sleep than the smart ones. but why should they sleep deeply at all? why should a state of such deep immobilization ever have evolved?

perhaps one useful hint about the original function of sleep is to be found in the fact that dolphins and whales and aquatic mammals in genera seem to sleep very little. there is， by and large， no place to hide in the ocean. could it be that， rather than increasing an animal's vulnerability， the university of florida and ray meddis of london university have suggested this to be the case. it is conceivable that animals who are too stupid to be quite on their own initiative are， during periods of high risk， immobilized by the implacable arm of sleep. the point seems particularly clear for the young of predatory animals. this is an interesting notion and probably at least partly true.

Breakfast

We get the energy for our movements from food. Human beings are just like machines. For us to work properly, we must be well energized. The energy, of course, comes from the three meals a day, that is, breakfast, lunch and dinner.

Breakfast is more important than any other meal in a day. For one thing, after a night’s sleep, most of the energy stored in the human body has been consumed. Breakfast serves the purpose of replenishing (fill up again) energy, thus making us energetic again. For another, in the course of a day, morning is the period of time in which we work with most efficiency. Without breakfast, the efficiency would be lost. Finally, the constant lack of breakfast can contribute to stomach troubles.

Therefore, to keep fit, we must have breakfast every day. It can be a cup of mild with some bread, or a bowl of porridge with some steamed bread, or anything else of the similar kind. Anyway, we must eat our fill (eat as much as we can), because a good breakfast can not only ensure our good health but also make a good beginning for a new day.

英语作文 篇3

You have bought a brand-new computer in a store。 But much to your disappointment， it could not be properly operated when you got it back。 Write a letter to the manager:

1) giving complaints，

2) describing the problems，

3) and asking for some compensations。

Dear manager，

I write this letter to you to make some complaints about the computer I bought in your store yesterday afternoon。 There＇ s something wrong with it。 That makes me extremely unhappy。

The computer cannot be properly shut down when I got it back to the office。 When I click the shutdown button， it seems that the machine gives no response。 And I＇m so annoyed with it。

It＇s obvious that you didn＇ t carefully examine the machine before you sold it。 I think your store should take full responsibility for selling me the defective machine。 I insist that you give me a satisfactory reply。 I do want you to give back my money as soon as possible。

Sincerely yours，

Tom
