袁隆平对自己的生活非常满足。但是，他对成名并不在意。他觉得出名后搞科研就不那么自由了。他宁愿把时间花在自己的爱好上。他喜欢听小提琴乐曲、搓麻将、游泳和读书。在自己身上花钱或者享受舒适的生活对他来说意义也不大。事实上，他认为一个人有了太多钱，他的麻烦事只会更多，而不是更少。因此，他拿出数百万元帮助其他人进行农业研究。
然而，梦想是不花本钱的。很久以前，袁隆平曾梦见水稻长得像高粱一样高，稻穗跟玉米穗一样大，而每粒稻米像花生米一般大。他从梦中醒来，希望能培育出一种能养活更多人的水稻。许多年后的今天，袁隆平还有另外一个梦想，那就是他的稻米可以出口以便长遍全球。一个梦想总是不够的，尤其对一个热爱和关心人民的人来说更是如此。

Today’s beef comes from animals raised on farms.So do chicken and pork.But some scientists are looking to change that.They’d like to grow just the parts that we want to eat.Create hamburgers, for example, without any cows.
Opinions differ on how best to do this.Some would start with animal
cells(细胞)．Others would reach for parts of plants instead.But whatever their source is, the goals are the same：tasty meat for more people, less stress on the environment.
The idea of growing just the beef, not the whole cow, has been around since at least the 1890s. And it got a bit more real in 2013. That was when Mark Post introduced his lab-grown hamburger at a televised tasting(品尝会)．But the cost of that first burger was high—more than $300，000.No one expected to buy a burger that cost more than a car, let alone a small plant.
Other scientists want to make “meat” from plants.These dreamers are not looking to create a better “vegetable burger”．Indeed, one of these scientists, Patrick O. Brown, doesn’t like that term at all.Vegetable burgers are made from plants and have the shape of a burger.The taste is often quite different from true meat.Brown’s company, Impossible Foods in Redwood City, Calif, instead wants to make plant burgers so delicious that even those meat eaters will enjoy them and want to take another bite.
When it comes to making meat，“Animals happened to be the technology that was available 10，000 years ago，” Brown says.“We stuck with that technology.But it is unbelievably inefficient(效率低的) by any measure.” Brown believes that science can come up with something better.His team is going towards the plant path. But if the scientists can make their animal-cell-based dream affordable, he adds，“I’ll be their biggest fan.”
【解题导语】 本文是一篇说明文。一些研究人员想利用植物生产肉或者在实验室里种

As hard as you and your loved ones try to pick out the perfect present, you may need to return something.The sweater will be the wrong size, or the new coffee maker won’t match your kitchen.
Almost everyone is in the same boat, though, with almost two-thirds of shoppers making a return over the holiday season, according to data from the National Retail Foundation.With numbers like that, a “quick” return or exchange can turn into a big headache for you.Luckily, if
you plan correctly, you can be in and out at once.
To avoid long lines, beat the crowds by arriving right at opening time, typically two hours before noon, says personal stylist Vanessa Valiente, creator of V-Style. “Most mornings at a store have shorter lines, but the mornings with the shortest lines are on Sundays，” she says.“This is true all through the year and continues to be true during the holidays.”
If you can’t get out on a Sunday, weekday mornings, especially Mondays and Tuesdays, usually have shorter lines too, says Sarah Hollenbeck, a shopping and savings expert.Hitting the shops on a weekday afternoon is also better than heading out after work or on a busy weekend, she says, but notes that the week after Christmas tends to be full of people no matter what.Stores offer New Year’s and after-Christmas sales, and shoppers gather for the things that weren’t checked off their Christmas lists.So many people avert that week. But for the best-of-the-best and the worst-of-the-worst, there are two days to notice.December 26 tends to be extra busy with people rushing out to make their Christmas returns immediately, says Valiente.On the other side, shoppers are more likely to stay at home on New Year’s Day.“If you take it easy on New Year’s Eve, you can be the only one in the stores doing returns on the first day of the year，” she says.

The National Pass walking track is in the Blue Mountains National Park, one of the most well-known national parks in Australia.It is near Wentworth Falls, which is around 100 kilometres from Sydney (the largest city in Australia)．It is a circular walking track of 4.4km.It includes a 709m climb
and takes around 3.5 hours to complete.Though the transport is not perfect, the National Pass can be readily reached by car or train.
The Grand Stairway is an unforgettable part of the National Pass.This is a zigzag stairway(which looks like a line of Z’s joined together) with 173 steps. It has been described as the tallest outdoor stairway in Australia.The Grand Stairway provides a way to the valley below Wentworth Falls.It was built around 1906 by workers who used all kinds of different tools.
Along a great part of this track is the amazing waterfalls which hikers(远足者) pass by, through, and over.These include the Empress Falls.This is a wonderful waterfall in the Valley of the Waters.It goes down a series of rocks to a pool.There are stepping stones for hikers to cross the falls and some shady spots where tired travelers can rest.
In 2002 the National Parks and Wildlife Service started repair work on the National Pass.This work took several years and the project was awarded recognition from UNESCO(United Nations Educational, Scientific and Cultural Organization) and the National Trust of Australia.
It is worthwhile to choose a guided tour package for the National Pass.The walk costs around
