The koala genome also revealed why koalas are such famously picky eaters. They are known to consume leaves from just 20 of Australia’s 60 known eucalyplus species. And even when they are in one of their preferred trees, koalas take leaf selection very seriously.
Information waiting to be discovered
Johnson said that the information encoded in the koala’s DNA is already being included in management strategies by conservation groups. However, she said the findings described in the new paper represent the early stages of what can be gleamed from the marsupial’s genome.
“The data is public, and I would love for anyone to start mining it and see what other amazing things they can find,”she said.“Once you have a genome of this quality, the sky’s the limit with what you can do with it.”

四、七选五
Directions：Complete the following passage by using the sentences given below. Each sentences can be used only once. Note that there are two more sentences than you need.
Can just one person make a difference? You bet! In a community every person counts, and getting involved is not difficult. Take stock of your own talents and interests. 1. Don’t wait for someone else to act first. Take the initiative! Once you see what you can accomplish, you’ll want to keep going.
Here are just a few ways to make a difference in your community. How many more ways can you come up with?
Clean up the community. People often throw litter in places where there is already litter. And the problem only becomes worse until someone gets fed up and does something. Could your neighborhood use a cleanup? Neighborhood cleanups are often sponsored by local businesses or schools. But if your community doesn’t have a cleanup program, get together with friends to organize one. You could pick up garbage in a larger area twice a year, or you could clean a smaller area every few months. 2.
Include the isolated. Do you know anyone who is housebound? Almost all neighborhoods have a few people who have to stay at their homes. These people are often elderly and unable to leave their homes to perform simple tasks. 3. By letting them“borrow”your legs and eyes, you can make them feel included. You can run errands for them like shopping or paying bills. They might like you to read to them if their eyesight is failing. Governments provide some of the services these people need, but programs cannot give them friendship; that’s what communities are for!
4. Reading clubs are popular all over Europe and North America. Members might read at home to prepare for discussion, or they might read aloud to each other and talk about what they just read. Either way, a book or article can spark lively discussion and this often challenges people to take action.
A. Cleaning your community will have a positive effect on others in society.
B. They find a need or an issue you really care about.
C. But they belong to the community, too.
D. Living in a clean neighborhood will be its own reward.
E. Don’t hesitate to take part in the community’s activity.
F. Round up some readers.

Small businesses hold the key to employed happiness. As the calendar flips to another year, many employees will consider starting the new year on the hunt for a new job.
In today’s changing workforce, it is more important than ever for companies to realize that a salary alone is no longer enough to attract or retain strong employees.
According to a survey by Aflac, small business deserve a round of applause for their ability to keep employees happy. The report found that 85 percent of small-business employees are happy in their current job, and more than half（51 percent）agree that most of or all of their happiness in their current job is a result of working for a small business.
Nearly a quarter of participants（23 percent）stated that the feeling of importance was the best part of working for a small business. Small businesses have the unique ability to make employees feel appreciated, respected and valued on a personal and professional level.
In a small-business environment, there are typically fewer layers between newcomers and leadership. This tight-knit structure can create a family-like atmosphere that allows employees to feel that their opinions matter and that they play a significant role in the business’s mission.
Flexibility is also vital in creating employee happiness. According to the report, 30 percent of respondents noted that flexible scheduling was the best part of working for a small business. A workplace that promotes healthy work-life balance can create happier, less stressed employees and can also increase productivity.
Although small business excel at keeping employees happy, there is always room for improvement. In a small-business community, money does not seem to be the only motivator. In fact, 65 percent of small-business employees indicate that an improvement in their benefits offerings would make them happier.
By offering a great benefits plan that includes voluntary benefits, small business can ensure that their employees are able to find the right benefits to meet their individual needs.
