How much therapy does a person need? The first day I joined Wayne State Medical School, the principal ________ me, saying, “There is a senior student who lost his leg in an accident. Before the accident, he was outgoing, always friendly. With the fitting of his artificial leg (假肢), he became lonely, ________ all of his friends. Please don’t say the word ‘leg’ in front of him.” I said, “Okay, I’ll ________.”

As a new teacher, I was not in a hurry. I waited until I knew the students well. It ________ three weeks. Then I chose three students — Jerry, Tom and Joe. I told them, “I’m going to play a joke. Tomorrow, Jerry, you go to the fourth ________, holding the elevator (电梯) up there. Tom, you stand at the head of the stair well and look down at the ground floor. And Joe, you stay on the ground floor pressing the elevator button and complaining that the cleaner is keeping the elevator up ________ she could get her mops (拖把) down.”

The next morning, everybody was there at 7:30, waiting for the elevator. I acted ________ to see them all. We talked about the weather. Then I said, “Why don’t you press the elevator button, Joe?” Joe said, “That stupid cleaner is keeping it up on the fourth floor.” Still further chatting, I began to ________ Joe to push the elevator button. At five to eight, the light was lit up on the second floor. I ________ the student with an artificial leg in one corner, saying, “Let us cripples (跛子) walk upstairs and leave the able-bodied to wait for the elevator.” So we started climbing upstairs. Tom saw us and waved at Jerry. Jerry freed the elevator, and the rest of the class came up on it. At the end of the hour that student got his social ________ again. I, who was also a cripple, helped him out of the status (身份) of a cripple. That gave him a new status.

If you’re looking to buy a gift for your children, why not choose something popular and get the best hoverboard?

What is a Hoverboard?

A hoverboard is a two-wheeled personal transportation device （设备）. It’s electrical and became highly popular in 2015 because of a popular 1980’s movie. Usually, this self-balancing device operates like a powered skateboard. _________                                                                                        

The device may have many designs, but the mechanism itself is simple. Basically, a standard hoverboard includes:

●Battery: stores the electrical power. Almost all hoverboards use a high-watt lithium-ion battery（高瓦锂电池）.

●Gyroscope （one for each wheel）: allows riders to tilt （倾斜） the hoverboard while keeping balance and changing their direction.

●Motor （one in each wheel）: provides the power to the wheels to keep the rider balanced and upright.

●Logic board: uses as the hoverboard brain. It deals with data-your speed, tilt, etc.-and sends information to the motors. This unit controls the power of the board so riders can change their speed.

All the above work together to control the power and tilt of the hoverboards so the rider is balanced, upright and moving at a suitable speed.

Where is a hoverboard legal （合法）?

Although hoverboards are wildly popular, they are still not “street﹣legal”. At present, some places don’t allow anyone under 16 to use these devices, like campus buildings, parks, shopping malls and subway stations. Some places have also put speed limits on the devices and set a limit to their use to bike paths. However, you are free to enjoy in open areas, including your yard.

Sunshine, beaches and coconut—many people think Hainan is a paradise（天堂）. But did you know it’s a paradise for plants and animals, too?

Hainan Tropical Rainforest National Park, in the south of Hainan Island, has the most concentrated and well-preserved tropical rainforest in China. President Xi Jinping visited it in April 2022.

The national park covers 4,269 square kilometers, or one-seventh of the island. More than 95 percent of the park is virgin forest and is home to 3,653 types of vascular plants and 540 types of terrestrial vertebrates（陆生脊椎动物）.

The park is the only habitat（栖息地）of the world’s most endangered primate（灵长类动物）—the Hainan gibbon（长臂猿）. They look like monkeys but have no tails. They live in trees and eat fruits and leaves from more than 130 plants. The number of Hainan gibbons has increased from fewer than 10 in the 1980s to 36 in 2022. This shows China’s achievements in environmental protection.

Not just a home to animals, the park is a “live museum” of amazing plants. More than 400 kinds of plants grow only in Hainan. Cycas hainanensis（海南苏铁）is a wild plant native to the island. With feather-like leaves, this plant can live up to 200 years old.

With so many plants and animals, the biodiversity level of the park is similar to that of the Amazon rainforest in Brazil. It’s a treasure for both China and the world.
