Read the passage and fill in the blanks with proper words.

A local primary school is considering using tablet computers（平板電腦）in all classrooms from next year. The following text has been written by a teacher at the school.

Should we use tablet computers in the classroom?

The use of tablet computers（or simply“tablets”）in the classroom has become an increasingly popular choice in many primary schools across the country, including many in our local area. It is important that we consider this opportunity, but we must also be a 1. of the problems.

On one hand, there are many a2.to use tablets in the classroom.

Firstly, tablets could improve productivity（ 效 率 ）during the school day. Because of their familiarity with computers and mobile phones, many of our students can type faster than they can write by hand. T3. , using tablets in the classroom could reduce the time it takes for them to complete tasks. Additionally, there are endless tablet functions（功能）which could provide interesting teaching a4.. For example, we could play computer games to teach Maths, or make simple flashes to show how magnets behave. Also, students could take photos outdoors and then use them for writing tasks.

However, we must also consider the possible problems with introducing tablets to our classrooms. Some students may play with the tablets instead of f 5. on their work. Another problem is that, while many students can use tablets already, many of our teachers are not good at it and would need to be trained. We may also have problems with the tablets breaking, which would be very expensive to r6. . This is in addition to the cost of buying the tablets in the first place.

All in all, even though using tablets in the classroom may have many problems, it seems that it would be a wonderful opportunity for students and teachers at our school. There are a lot of costs indeed, but it would c7.prove to be a worthwhile investment（物有所值的投資）.

International Day for Protecting Consumers’ Rights

Began:1983

Date: March 15 each year

The International Day for Protecting Consumers’ Rights aims to pay special attention to the consumers and remind consumers of their rights（權(quán)利）.

The consumers’ rights are legal(合法的） and protected by laws. A consumer shall have the right to get information relating to consumption(消費(fèi)) and the protection of the rights and interests of consumers. And the whole society shall bear responsibility for the protection of consumers’ legal rights and interests.

There is no doubt that fake(假冒的) and unqualified(不合格的）products are extremely harmful. They endanger people’s health and even threaten people’s lives. So as consumers, we need to protect our rights. When we find the products are fake, we have the right to ask for compensation(賠償).

Protection for Consumers:

*Every year, the “3.15 ” evening party hosted by CCTV unveils(揭幕) some illegal companies and fake products, in order to raise the consumers’ awareness to protect their own rights.

*If consumers find the shops are cheating, they can call 12315 to protect their rights.

Several strong measures should be adopted to fight against fake and unqualified products. On the one hand ,those who make bad products must be seriously punished by the laws. On the other hand, consumers should learn to know differences between true and false.
