The home of the future won't be     1    (complete) different and we will be living in houses and flats just as we do today.     2    (build) in different shapes, no two homes will look the same. People will be able to buy “house kits” containing a basic house structure, with adjustable walls, doors and windows. They will put together the different parts     3     (create) the home they want.

Space holidays will develop in the future, but these holidays won't be for everyone because they are     4     (expensive) than holidays on the earth. Short space trips will develop first, then the space hotels will go around the earth     5    it will be possible to have a longer vacation. By     6    end of the next century, there will be holiday centres on the moon with leisure facilities for families.

According to the laws of physics, the earth is going to    7    ( appear) some time in the future. This isn't going to happen tomorrow but scientists predict that it will happen in five billion years when our sun    8    (explode).     9     a result,we will have to explore the universe and find another home. At some point in the distant future, either we stay on the earth and die with it,or we leave and move to another planet. There won't be any other    10    (choose).

2 . The biggest seasonal change of the year happens from March to June, as temperatures climb, days lengthen, birds return, and life in all forms comes rushing back.     1

That's the energy of the season: powerful, creative, determined. That makes it the perfect time to get serious about your health and fitness.

Write down your workout goal --- building new strength; perhaps.    3     "What have you been telling yourself you can't do?" asks Larsen. Spring is the time to question those assumptions and deal with them head-on.

    4     It's challenging for many, and it promotes growth and change: Hiring a trainer -- -- or joining forces with an enthusiastic partner or group --- can help build confidence, whether you're an experienced lifter or nẹw to the world of weights.

You can make use of the seasons' growth- inducing (促生长的) power by increasing your fitness program.    5    If you are a yogi, make great effort to master tougher and more athletic asanas(体式).

Whatever you choose, remember that by taking advantage of the opportunities of each season, and avoiding the difficulties, you can gain a deeper appreciation for your body's changing needs---one year, one season, one workout at a time.
