How can teachers best lead language classes, special education classes, or communication classes while protecting 【小题1】（they） and their students? Since this fall, American teachers 【小题2】（consider） that very question all the time.

With some students 【小题3】（ come） back to school for classes, teacher have begun experimenting with unusual objects, special kinds of masks or face coverings, and even 【小题4】（ protect） bubbles. Stephanie Wanzer is a teacher, 【小题5】 major is special education, which is a term for classes with students who have special needs because of physical or learning issues.

While teaching, Wanzer would like her smile 【小题6】（ see）, so that they know she is happy. 【小题7】 , they cannot see her face because of her mask. Instead, Wanzer uses 【小题8】 unusual object — a stick with an image of a smile. Wanzer 【小题9】（recent） described working with one student to the Associated Press. "I try to be really expressive with my eyes, “ she said. "He's staring at me and I'm uncertain 【小题10】 he thinks Pm mad or delighted as he can't see my facial expressions, she said.

There are two kinds of parents in modern America, says Alison in her recent book, the Gardener and the carpenter. The “carpenter”(木匠) thinks that his or her child can 【小题1】 (shape). The idea is that if you just do the right things, get the right skills and read the right books, you’re going to have the ability 【小题2】 (turn) your child into a particular kind of adult. The “gardener”, on the other hand, is less concerned about controlling who the child will become. Instead, he 【小题3】 (provide) a protected space for the child to explore. The style is all about “creating not only 【小题4】 rich, nutritious but also various and energetic ecosystem”. Gopnik, a psychology and philosophy professor, spent decades 【小题5】 (research) children’s development and found that parents often focus too much 【小题6】 their children’s future. The harm is that parents and their children may become anxious, tense or unhappy. These parents should really reflect on 【小题7】 (they). “We’re so concerned about what these children are going to be 【小题8】 we’re unwilling to give them the right to take 【小题9】 (risk) and explore the world,” she says. Obviously, the 【小题10】 (little) parents worry about their children’s outcome, the better their children may live in life.

A science lecture 400 kilometers above Earth was delivered by Chinese astronauts on China's Tiangong space station, 【小题1】 they displayed unique physical phenomena in the orbiting spacecraft. Featuring interactive teaching, it was mainly targeted at youngsters.

In 2013, 【小题2】 the assistance of two other crew members, Wang Yaping delivered the country’s first space lecture, making China, following the United States, 【小题3】 (become) the second country to carry out a space lecture.

Compared with the class nine years ago, this 【小题4】 (year) lecture was greatly different. Apart from a bigger “classroom”, it covered a 【小题5】 (wide) range of subjects. Previously Wang showed students the laws of physics and the phenomena of 【小题6】 (weightless) in space. But this year, biology 【小题7】 (add). The astronauts compared the growth and shape of cells in different environment to study their 【小题8】 (change) rules.

【小题9】 these space lectures showed various topics, the aim behind never changed. According to China Daily, the space lectures aim to “spread knowledge about 【小题10】 (man) spaceflights and spark enthusiasm for science among young people”.
