Genes that control factors such as size, color and shape determine the differences in fruit. And now that scientists have discovered how to detect different genes, farmers can hand over a young and tender branch to have its genes checked prior to planting. It works the same way as a detective checking fingerprints. Once farmers know which trees are good and which are bad, they can discard the bad ones. Farmers can even create new varieties according to their individual tastes.In the past three years, tens of thousands of tests were carded out to determine the genetic (基因的) features 0f fruit. Zhang, a Chinese scientist, showed a photo of a DNA-test and pointed to the shining lines on it, saying thatthe lines were genetic signs that tell us what a tree's fruit will be like. For example, the ordinary pear tree bears fruit after four years. But now it only takes a month to test the DNA from a young leaf and a farmer will know everything about its fruit. By mixing different types of trees with suitable genes, farmers can create whatever fruit trees they want.

For anyone who hates doing yard work, your new best friend may have arrived. A robot can autonomously shovel snow, collect leaves and cut grass.

“We’re trying t o help people not spend time on yard work,”said Steven Waelbers, the designer of t he robot. “We want people to enjoy t heir free time with their family.”The electric robot can run by itself in right directions with the help of two beacons(信号塔) that must be placed in the yard. the robot includes a camera and ultrasound sensor (超声传感器) that Waelbers said would stop quickly when it finds pets and people.

Owners of the robot will need t o regulate t he values stored in the robot. then it will confirm the task it’s going to take. Before the robot operate by itself, an owner must manually wheel it around the yard 一 taking it around any obstacles like trees, bushes or mailboxes. By doing this, the robot is taught how long and wide the lawn is, and won’t accidentally(不小心) destroy your rose hush or run to the neighborhood.

Once this setup is complete, and the $3,999 robot has been trained on where to cut grass, rake leaves and shovel snow, it operates without any supervision.

Waelbers has always loved to build robots and play with electronics. He started work on a high-tech company after his father asked him to make a robot that would shovel snow for him. Waelbers plans to start sales in early 2017.

B. help people keep healthy and fit

C. make people enjoy family time

28.the robot would stop in front of pets and people thanks to()

A. the remote controller

B. the ultrasound sensor

C. the big and square yard

29. Which of the following steps should be done in the first place?()

A. An owner must wheel the robot around the yard by himself.

B. The robot learns and stores the length and width of the lawn.

C. The robot operates the task it’s going to take without supervision.

30. Which of the following about Waelbers is TRUE?()

A. He didn’t love building robots when he was a young boy.
