Want to travel easily? Here are some tips that help you reduce the size of your luggage.

    Roll clothes instead of folding them. Many people try to fold their clothes into their little suitcase.{#blank#}1{#/blank#} It actually makes far more sense to roll your clothes rather than fold them. Starting from the bottom, roll up your clothes into very tightly packed cylinders (圆柱体) which you can stack (堆叠) on top of each other.

    Use vacuum bags (真空袋), when possible.{#blank#}2{#/blank#} Buy some vacuum bags and seal all of your clothes up tightly. Having all of your luggage vacuum sealed will reduce the size of your items greatly. That will allow you to take more of what's needed.

    Always take travel bottles. Even though you are allowed to take full sized bottles in your suitcase, to make sure that you are under the weight allowance, it's recommended that you still stick to travel-sized bottles.{#blank#}3{#/blank#} Besides, it will also prevent you from wasting any product. If you do run out of anything while you are on holiday, you can always buy more.

    {#blank#}4{#/blank#} If you do need to take a coat, you can wear it on the journey so you don't have to pack it in your suitcase. Another method you can use is wearing multiple layers (多层衣服) on the journey although this isn't always the most comfortable.

    Research the weather in advance. A great way to prevent packing clothes that you won't end up wearing is to research what the weather is going to be like where and when you go on holiday.{#blank#}5{#/blank#} You can know how hot it's likely going to be, as well as how much rain on average the destination receives each month.

A. It will free up enough room for you.

B. Don't put any shoes in your suitcase.

C. It will make your suitcase much lighter.

D. Purchase a high and soft-sided suitcase.

E. Wear anything that takes up a lot of room.

F. There are plenty of websites that can predict it.

G. This is not the best way to pack your holiday goods.

    Health is the most important thing in the world. Nothing is more important than health. If one takes away our money, houses, cars, or even our clothes, we can still survive. {#blank#}1{#/blank#} That is why we always try to eat in a healthy way and exercise regularly.

    How can we keep healthy? In order to eat healthily, I usually avoid eating food high in fat, like French fries or cookies, which are junk foods. Besides, I only eat a little meat. {#blank#}2{#/blank#}

    {#blank#}3{#/blank#} Taking exercise every day helps us build a strong body. Regular exercise is an important part of keeping me healthy.

    What's more, I think friends are an important part of one's health.{#blank#}4{#/blank#}I always feel better when I am with friends than when I am alone. When I am with my friends, I always laugh. Laughing is also an important part of health. It is good to stay with my friends.

    By eating properly and exercising regularly, I can keep my body at a proper weight and keep healthy. By spending time with my friends, I can keep my mind as well as my body happy. These things sound easy to do, but not many people can manage them.{#blank#}5{#/blank#}

    Every animal sleeps, but the reason for this has remained foggy. When lab rats are not allowed to sleep, they die within a month.{#blank#}1{#/blank#}

    One idea is that sleep helps us strengthen new memories. {#blank#}2{#/blank#} We know that, while awake, fresh memories are recorded by reinforcing (加强) connections between brain cells, but the memory processes that take place while we sleep have been unclear.

    Support is growing for a theory that sleep evolved so that connections between neurons (神经元) in the brain can be weakened overnight, making room for fresh memories to form the next day.{#blank#}3{#/blank#}

    Now we have the most direct evidence yet that he is right.{#blank#}4{#/blank#} The synapses in the mice taken at the end of a period of sleep were 18 per cent smaller than those taken before sleep, showing that the connections between neurons weaken while sleeping.

    If Tononi's theory is right, it would explain why, when we miss a night's, we find it harder the next day to concentrate and learn new information — our brains may have smaller room for new experiences.

    Their research also suggests how we may build lasting memories over time even though the synapses become thinner. The team discovered that some synapses seem to be protected and stayed the same size. {#blank#}5{#/blank#} “You keep what matters,” Tononi says.

A. We should also try to sleep well the night before.

B. It's as if the brain is preserving its most important memories.

C. That's why students do better in tests if they get a chance to sleep after learning.

D. Similarly, when people go for a few days without sleeping, they get sick.

E. The processes take place to stop our brains becoming loaded with memories.

F. Tononi's team measured the size of these connections, or synapses, in the brains of 12 mice.

G. “Sleep is the price we pay for learning,” says Giulio Tononi, who developed the idea.

    As we all know, the spine (脊柱）stands at the center of your health, providing your body with structure and support. It also contains your spine cord (脊髓) a massive collection of nerves conveying electric signals from the rest of your body to your brain.{#blank#}1{#/blank#}.

    Maintaining good posture is one of the most important things you can do to keep your spine healthy. Proper posture means standing or sitting while keeping your spine straight, except for its natural curves. Posture comes into play even when you are asleep. Sleeping on your side puts less stress on your spine than most other positions. {#blank#}2{#/blank#}. Especially if you work at a desk most of the day, it's important to get up and stretch regularly.

     {#blank#}3{#/blank#}. Stretch can help the muscles around your spine relax and allow bones to shift into better arrangement. Strength exercises like push-ups (俯卧撑）can also help by strengthening the muscles around your spine. However, don't overdo the exercise, as repeated movements can strain the muscles around your spine.Finally, your diet affects the health of your spine because many vitamins arc necessary for bones and nerves. In particular, vitamins B and D are essential to keep bones healthy, so you may want to consider taking a supplement (补充). {#blank#}4{#/blank#}, so it is also helpful to do some of exercise outside.

    Many of the actions necessary to keep your spine healthy are identical to those used to preserve your health in other ways. {#blank#}5{#/blank#}.

A. It can be hard on your back to stay still for too long

B. So protect your back, the rest of the body will benefit

C. However, the latter can also be absorbed from sunlight

D. Doing yoga to protect your spine is also a necessary step

E. Exercise is also an important factor in your spine's health

F. Try the following exercises to keep your spine more flexible

G .So, to have a healthy spine, you should take the following factors into account

    Once eating alone was just that: sitting down in a restaurant on one's own and eating a meal. Everyone did it sometimes, and when they did so, {#blank#}1{#/blank#}. To eat alone might suggest that you didn't have any friends. There was a kind of shame attached to it.

    Nowadays, however, there is more and more solitary (独自的) eating for pleasure. {#blank#}2{#/blank#}. "Foodies"—people with a passionate interest in cuisines—do it because all they need is the chance to eat good food. They don't want company or conversation, but only the joy of eating some special dish. Other people eat alone because it's simply practical for them to do so. For instance, it's estimated that nearly a third of all the customers of fast-food restaurants eat alone. They are served with their food fast, eat it fast and then leave fast. {#blank#}3{#/blank#}.

    But the appeal of eating alone is quite different. {#blank#}4{#/blank#} . For the hour or so that it takes to have a meal, they can forget all the pressures of their lives. They don't have to deal with their family or job. They can relax and let their mind wander. Maybe they'll bring a book, a newspaper to enjoy a quiet time.

    David Annand, editor of Conde Nast Traveler magazine, who delights in dining alone, speaks of his pleasure in the "rhythm of a meal in a restaurant—its ebb and flow (人来人往), the periodic arrival and departure of the waiter". {#blank#}5{#/blank#} .

A. It's an experience of freedom

B. they might be a little embarrassed

C. People choose to eat alone for various reasons

D. none of them would feel bad about themselves

E. Sometimes staying alone is quite cosy when you don't work

F. This restaurant rhythm allows him to sit back, observe and think

G. It saves time if they have a meeting or a child to pick up from school
