As a parent, I’m torn by society’s love affair with phones. On the one hand, it’s awesome to be able to know that our kids have a means of     1     (keep) in touch with us in an emergency. On the other hand, I know I somehow managed     2     (survive) my childhood as well as the majority of my life to date without a 24/7 means of communication.

So I often think whether kids     3     (real) need to have phones at school. During the past year, schools     4     (try) to carry out a “no electronics” policy but have met with strong disagreement from parents     5     want their kids to have access to a phone in case of an emergency (紧急情况). However, a 2015 study found kids did better in school when mobile     6     (device) were banned (禁止).

According to     7     study, teen’s test scores increased by 6 percent after phone bans were applied. The results were even     8     (good) for kids who were struggling academically, whose scores improved by 14 percent after the ban.

So what’s your opinion? Ban phones and leave kids without a means of communication,     9     allow their grades to suffer because     10     the unavoidable distraction (分神) of technology?

Is there anything nicer than a cooling ice cream on a hot summer’s day? This       1     (freeze) dessert is old, but our tastes and consumer habits are changing. How is the ice cream production process changing, and who is driving it?

The recipe is simple, just a     2     (combine) of milk, sugar and fat. But the process is complex,     3     demands time and energy to get the materials mixed, heated, and then cooled. Designers are working     4     (improve) the production process with new equipment. For now,     5    , even with the help of robots, it can take up to two years from testing a new treat to being available to consumers.

So, what new things can we expect? It is millennial (千禧年的) consumers who are driving interest     6     more flavours. They say the tastes for today’s ice cream products     7     (limit) only by our imagination. But according to Elsebeth Baungaard,     8     expert in economy, the next trend will be     9     (little) about innovation and more about size. “I’m sorry to say it’s     10     (simple) reducing in size”, she says, “but the quality will be higher.”

It is a special cross-country race. The competitors’ vehicles are made     1     fruits and vegetables like carrots, eggplants, grapefruits, pumpkins and oranges. They are the creations of pupils from the Shanghai World Foreign Language Primary School.

According to Chen You, the science class teacher,     2     (base) knowledge had been taught within 6 classes to students before they drew sketches and     3     (choose) vegetables to make a food car.

Although students were encouraged     4     (design) their cars together with parents, all the cars should be made in the class. After     5     (bring) piles of ingredients as well as tools the children began their innovation. Some cut the carrot slices to make them round, and some others assembled (组装) their car components together.

In addition to the     6     (compete), students are required to reflect on the     7     (difficulty) they encountered making their vehicles,     8     things they have learned from the activity and the improvements they think the course can make.

    9     touched the teachers most was the unity and friendship among the children. For example, although the contest was fierce (激烈的), students felt     10     (excite) for the champion car as if they themselves had stood out, and when a girl’s car fell apart their friends comforted her and helped reassemble the car.

It's estimated that two-thirds of people online have had their personal information     1    (steal).

Faced with such a range of     2    (threat), it's easy to focus on technology investment. Firewalls, anti-virus protection and every other kind of technology can be threatened as well. That's not to say that     3    (invest) in IT security isn't important. But the cybersecurity (网络安全) threat needs individuals     4    have skills, talent and experience     5    (bad). Indeed, there will be a global shortfall of 3. 5 million cybersecurity jobs by 2021.

Only with people power can we win the online security war. Here     6    (be) the main reasons and methods.

First of all, it is important to improve the security     7    (aware). Security is becoming important, with organizations starting to understand the big role that individual employees must play.

Secondly, pay attention     8    grassroots education. As we face a significant skill shortage in the future,    9    is of great importance that together we help create the next generation of cyber defenders now.

Thirdly, encouraging skilled staff also matters. Most organizations have concerns about security skills, and two-thirds have trouble     10    (encourage) the security staff they have.
