【題目】下列關(guān)于赤道的敘述,正確的是(

①赤道是劃分緯度的起點(diǎn)線,是90°緯線 ②赤道是劃分經(jīng)度的起點(diǎn)線,是0°經(jīng)線 ③赤道是南半球和北半球的分界線 ④赤道是南、北緯度的分界線

A.①②B.①④C.③④D.②③

【答案】C

【解析】

根據(jù)緯線是在地球儀上,順著東西方向,環(huán)繞地球儀一周的圓圈。所有的緯線都相互平行,并與經(jīng)線垂直,緯線指示東西方向。緯線圈的大小不等,赤道為最大的緯線圈,從赤道向兩極緯線圈逐漸縮小,到南、北兩極縮小為點(diǎn),進(jìn)行分析解答。

赤道是劃分緯度的起點(diǎn)線,是0°緯線,故①錯(cuò)誤。

本初子午線是劃分經(jīng)度的起點(diǎn)線,是0°經(jīng)線,故②錯(cuò)誤。

赤道是南半球和北半球的分界線,故③正確。

赤道是南、北緯度的分界線,故④正確。

故選:C。

【題目】 Who cooks in your family? Who cleans the clothes? Who washes the dishes? Who t1care of the baby? Maybe on most days, the answer would be your mother. But not on the second Sunday of May. On that day, it's you and your father.

That's because the second Sunday of May is Mother's Day. Mother's Day is a day to appreciate and give t2 for all the things that mothers do for the family.

One way people can do that is by doing all of her chores(家務(wù)活) for her. For example, one tradition in the US is for the father and children in a family to cook breakfast for the mother and do housework. Mothers get to be very lazy on this day. It's probably their favourite h3.

Another thing you can do is to give her a gift. Fathers will often buy their wives flowers or chocolates. Children often make them gifts. For example, they might draw their mom beautiful c4 or make a nice necklace out of candy.

But the most i5 thing to do on Mother's Day is to show your mother you love her. Any way you do it is fine. Sometimes, the best Mother's Day present is a hug.
