Do you sleep well every night? Studies show if we have a good rest, we must have more energy to study. At the same time, we will be healthier.

The sleep environment is very important to us. The bedroom is the main place where we sleep at night, so its environment directly affects the quality of our sleep. 【小题1】 So we should advise our parents to pay attention to our bedroom environment.

【小题2】 The bedroom light should be neither too bright nor too dark. If the light is too dark, it will affect people’s eyesight. If the light is too bright, it can affect the speed of falling asleep. So we should choose a kind of yellow light that gives feeling of warmth.

【小题3】 Many old people like to put a lot of flowers in the bedroom. Of course these flowers can make us relaxed and feel well. But there are too many plants in the bedroom, which can really affect people’s sleep quality.   【小题4】

Our bedroom should be ventilated (通风的) often. 【小题5】 Otherwise, we may find it difficult to breathe, which can affect our sleep quality.

Below is a housing guide for students going to London.

University accommodation（住所） office

Many university accommodation offices have their own lists of registered landlords （房东）. The advantage of using them is that you can get some support if you have a problem. But they are unlikely to have enough registered landlords to house all their students.

Accommodation companies

They usually have a large number of accommodations. A good company can save your time in looking for the right accommodation quickly.

Notice boards

Around the universities you will find a number of notice boards. These will either be from landlords or from students. Some universities also have online notice boards where students can advertise to other students.

Word of mouth

Some of the best housing in London is never advertised but is passed on from one group of students to another by word of mouth.

Loot

Loot offers information about private housing for co-renters. The advantage of using Loot is that there are some good bargains（特价房）.

Many people use computers, but few of them know how to look after them. Remember the following when you use your computers.

Keep your computers in a cool, dry room. 【小题1】 Moisture (潮湿) is also bad for them. Most computers work best at a temperature of 5—30.

【小题2】 Smoke of all kinds is very bad for many parts of a computer and can cause many problems.

【小题3】 Pieces of food and a little water in the keyboard can also cause many problems.

Make sure that the keyboard and screen are at the right height for you. 【小题4】

If you wear glasses, make sure these glasses are right for using the computer. 【小题5】

Keep your screen clean and don’t have it too bright. A dirty screen can hurt your eyes. A very bright screen can also be bad for your eyes.
