Today we are making banana nut ice cream. Right now, different kinds of nuts are being chopped (切碎) in a large chopper. It’s a very expensive machine, but it chops nuts very quickly.

When the nuts and bananas are ready, they     3     (add) to the sugar and cream in a special machine that     4     (invent) by Betty a few years ago.

When my friend first suggested we join the tai chi club, I     1     (hesitate) for I always believed tai chi was for old people.     2    , I had to admit that I had been wrong about tai chi. The most interesting things of the first few tai chi classes     3    (catch) my imagination were the moves and their descriptive names.

Initially, people believed it was Zhang Sanfeng     4     had invented tai chi after drawing     5    (inspire) from a fight between a snake and a crane. But nowadays Chen Wangting is believed     6     (invent) tai chi based on martial arts skills.

After learning the basic of tai chi I found myself     7    (bore) and aching from doing the same moves over and over again. But thanks     8     my coach’s guidance, I learned how to relax my muscles and focus on peace of mind     9     performing the routine.

In a word, after a year of practising tai chi, I was amazed at its significant effect on my physical and mental health.     10    , tai chi has inspired me to explore Chinese culture behind it.

The key to China’s future lies in the younger generations. A strong body is important for the     1    (develop) of young people.

In schools, the class hours for physical education continue to increase. More than 37 million rural students     2    (receive) compulsory education (义务教育) have benefited from the student nutrition improvement program.

When skateboarding (滑板运动) started in 1960s, skateboards     1    (make) of wood and had clay wheels. Since the wheels didn’t hold the concrete firmly, the riders could do very few tricks with them. In 1973, a new wheel made of a plastic     2    (call) urethane (氨基甲酸乙酯) was invented in California. A skateboard     3     these wheels moved very quickly and it also held the concrete well. During the next few years, skateboards were     4    (far) improved. The urethane was perfected, and the boards were shaped better. These skateboards gave new life to skateboarding.

Although skateboarding was easy     5    (ride), the streets weren’t safe for it. As a result, skateboard parks sprang up. The first parks     6    (appear) in California and Florida. But at first there were only outdoor parks     7     had concrete slopes with small curves (曲面). The more exciting parks appeared which had steep downward slopes, banked curves     8     vertical walls. Today there are both indoor and outdoor parks where the riders must wear helmets as well as knee and elbow pads, which can avoid serious injury when     9     rider falls down. Whenever they ride, people should always use the safety     10    (equip). Many accidents happen during the first week of riding, so it’s of vital importance to learn how to fall safely.
