When a company wants to increase the sales of a product, it will usually advertise. An advertisement 1..tells.........us what products are available and it also (approves / suggests / wins / persuades)2...........us to buy a particular product. Today’s television advertisements (arrive/pass/reach/spread)3...........millions of people, but the first forms of advertising were much more local. Market traders shouted out what they had for sale and large signs (has/were/had/are)4........... displayed outside shops. Modern advertising began about 150 years ago, (which / whether / why / when)5...........factories started producing goods (in/at/for/by)6...........large quantities. Before long, advertisements for a wide (area/row/range/pack)7...........of products appeared in national newspapers. Nowadays, we see many different (methods/kinds/systems/ways)8........of advertisements. They can appear on the sides of vehicles and on the clothes we wear as well as on television and radio. But the (aim / plan / attempt / wish)9.........of all advertisements is the same. They try to (pull / achieve / bring / attract)10.......our attention and get us to buy a particular product.

We live in an age when many parents allow their children to use smartphones soon. As far as I am concerned, children using smartphones when they were young can be bad, those kids could have reduced eyesight, and furthermore, they increase the risk of brain cancer highly, so bad for their health! Anyway, on the internet, there are a lot of complicated problems and bad parts who could hack pieces of information about your children, extremely dangerous if kids are not careful. Parents' views on the matter, they let kids use phones cause they want them to serve the purpose that studying or some parents do it just to make their kids stay away from bothering their parents. Some kids don't perceive the limits on time to use phones, they may use them almost during the day. Besides children's health effects, by using smartphones so much, the kids couldn't play in outdoor activities, so they won't be so vivacious, and difficult to make friendships with others. Long story short, children can study, entertain, contact, etc with their phones. It is so good if they know how to use phones in a limited time and carefully using. However, using smartphones can have negative impacts, pay attention to your children, and don't let them have those impacts.

Ý cậu là viết đoạn văn à, cậu ghi đầy đủ đề ik.

Nếu ở đây của bạn là khu vực khí hậu ôn đới lục địa thì mik xin trl =):
- Mùa hạ nóng và có mưa, băng tan nên sông nhiều nước.
- Mùa đông lạnh, kéo dài, có tuyết nên sông đóng băng, đặc biệt vào sâu trong lục địa khí hậu càng lạnh khiến sông đóng bằng càng lâu.

a. Xét △ABD vuông tại A và △EBD vuông tại E:
\(\widehat{ABD}=\widehat{ABE}\)  (BD là tia phân giác \(\widehat{ABC}\))
BD chung
=> △ABC= △EBD (ch-gn)
b.
△ ABC= △ EBD => BA=BE; AD=DE
=> B ∈ đường trung trực của AE (1)
=>  D ∈ đường trung trực của AE (2)
Từ (1) và (2) => BD là đường trung trực của AE
c.
Áp dụng định lý Py-ta-go vào △ BED có:
BD²=BE² + DE²
BD² = 4² + 3² = 16 + 9
BD² = 25
=> BD = 5 cm
d.

Xét △EDC có: DC > DE (cạnh huyền > cạnh góc vuông)
Mà DE=AD nên AD < DC

Tui thấy rõ câu này hoi, ko bik còn nx ko
