As    1     teenager, I often heard people say, “High school is the best years of life!” I So I looked forward     2     beginning a new life as a freshman.

    3     (actual), there were really too many unforgettable moments in those years. Whether/they were bad moments or amazing ones, all of them left a deep     4     (impress) on me.

During those years. I liked to volunteer and took an active part in debate. I     5     (behave) responsibly and never quit before     6     (challenge) And it was at that time that I met my best friend Ann, a unique (独特的)   and lovely girl. Just like me, she was also active, helpful and curious     7     (explore) everything on campus. She would help me whenever I was in trouble and would give me     8     (confident) whenever I lost heart. She was the best friend in my youth.

Other than voluntary work, I also liked sporting events,     9     are the most exciting parts of the high school life. On sports days, all the students would show up to cheer for     10     (they) sports teams. The shouts, the cheers, the sighs and all the noise you can think of were all brought into one place. What a happy sight!

I really miss my high school life.

Dubai was a 6,000-person fishing village half a century ago. Since 1966, when oil was discovered there, the population of Dubai has grown    1    2.6 million. Over the years, it has become a well-known tourist destination.

What attracts tourists to Dubai are tax-free shopping, dry weather, excellent    2     (accommodate), delicious food and beaches that go on for miles. In fact, some people come here only     3     (experience) the shopping. There are lots of shopping centers,     4     (provide) every famous brand you can name. Those outdoor markets sell everything from spices to gold at fair prices.

Choosing what places to visit in Dubai is difficult, because even the hotels there are also amazing    5     (attract). The Burj A1 Arab is considered one of the world’s best hotels,     6     is located on its own island, about 1,000 feet offshore from Dubai. Built in the shape of    7     ship, this hotel is still     8     (tall) than the Eiffel Tower and nearly as tall as the Empire State Building. Certainly, there are also other great places of interest to visit.

Indeed, traveling around this country will    9     (true) give you an amazing experience because of its interesting things offered to all types    10    tourists.

Currently, many major cities in China are carrying out the waste-sorting policy, with the purpose of changing the traditional waste     1    (treat) and protecting this delicate environment we live in. What     2     encouraging measure!

The new method,     3    (compare) with the traditional way of collecting wastes, has brought a variety of benefits. First, wastes     4    (send) to different factories according to their classification rather than landfills,     5     they would be simply burnt and buried. What’s more, waste classification not only cuts the spending     6     treating wastes, but also brings some interests. Recyclable wastes, such as paper, glass and plastic, can be reused after     7    (process) in related factories, while other wastes can be turned into the valuable.

As a result, waste classification should be     8    (immediate) carried out as an effective means of environmental protection. The citizens are supposed     9    (take) action, sorting wastes before they throw them away. Meanwhile, it would be rather     10    (help) if we could influence as many people around us as possible.

It is common to see people concentrate on     1     (they) smartphone screens on busy streets. But walking and texting can put people in     2     (dangerous) and cities in the United States and Europe have made great efforts to deal     3     it.

In Honolulu (火奴鲁鲁), using the phones while crossing the street is forbidden. It has passed     4     law to forbid people to use a mobile while crossing the road. In other words, do not look at a screen when you cross the street     5     you could be fined. Honolulu is the first major US city     6     (forbid) what is called “distracted walking”.

People who text while walking are nearly four times     7     dangerous as those who don’t have the habit. Using phones while walking may lead to injuries and deaths,     8     seems to be a global problem. Pedestrian (行人) deaths     9     (increase) because of the use of cellphones in the past 5 years, and it is expected that the tendency will continue.

In a town of Germany, special lights on the ground to remind people of danger were used after a teenager using her smartphone was hit and     10     (serious) injured.

Special attention should be paid to the problem.
