题目内容

【题目】夏季干旱地区的绿洲、湖泊最高气温比其毗邻的沙漠戈壁低30左右,这是由于周围戈壁沙漠的高温气流在大气的平流作用下,被带到绿洲、湖泊上空,形成了一个上热下冷的大气结构,形成一种温润凉爽的小气候,这种现象就称之为冷岛效应。据此完成下列问题。

【1】冷岛效应形成的根本原因是

A受控大气环流的差异 B阳光照射强弱的差异

C绿洲与沙漠热力性质差异 D绿洲与沙漠距海远近不同

【2】冷岛效应会使绿洲地区

A年降水量增多 B热量交换变缓

C水汽蒸发加快 D地面风速增强

【答案】

【1】C

【2】B

【解析】

试题分析:

【1】根据题干周围戈壁沙漠的高温气流在大气的平流作用下,被带到绿洲和湖泊上空,形成了一个上热下冷的大气结构,则其中戈壁沙漠的高温气流是由于戈壁沙漠、绿洲比热容大小根本原因是热力性质差异,C对冷岛效应并没有形成大气环流,而是形成一个逆温层,A错。绿洲和湖泊、沙漠所在地一样,因此距海远近和阳光照射相同,BD错。故选C

【2】绿洲、湖泊上空的冷岛效应,使下层冷空气得以保持稳定,热量交换减缓,B对。下层冷空气,气温低抑制了植物的蒸腾和地面的蒸发,C错。但水汽蒸发量减少,且高温气流在上层较难形成降温条件,所以年降水量减少,A错。大气结构稳定,地面风速也随着减弱,D错。故选B。

The Royal Mint has chosen Beatrix Potter’s thieving Peter Rabbit as the first character from children’s literature ever to appear on a UK coin.

Peter, pictured in the blue jacket that he is forced to abandon in the garden of Mr McGregor when he is caught stealing vegetables, is captured on a special, coloured edition of a 50p coin available from now. The Royal Mint, which described Peter as “the most recognizable of Potter’s creations, and one of the most cherished from children’s literature”, will release uncoloured versions of the coin in change later this year.

Three more of Potter’s characters will also be committed to currency later this year, as part of celebrations marking 150 years since the children’s author’s birth. The images have been created by coin designer Emma Noble, who said it was “amazing to be given the opportunity to work with such famous and treasured literary characters”.

Potter’s The Tale of Peter Rabbit, featuring Peter and his better-behaved siblings (兄弟姐妹) Flopsy, Mopsy and Cottontail, was the first of her stories to be published, released in 1902 by Frederick Warne & Co.

Scientists have discovered thirteen kinds of vitamins. They say vitamins help to carry out chemical changes within cells. If we do not get enough of the vitamins we need in our food, we are at risk of developing a number of diseases. Which foods should be eaten to keep us healthy? Let us look at some important vitamins.

Vitamin A helps prevent skin and other tissues from becoming dry. People who do not get enough vitamin A cannot see well in darkness. Vitamin A is found in fish liver oil and the yellow part of eggs.

Vitamin B-1 is also called thiamine. Thiamine changes starchy(含淀粉的)foods into energy. Thiamine is found not just in whole grains like brown rice, but also in beans and peas, nuts, and meat and fish.

Vitamin B-12 is needed so folic acid can do its work. Together, they help produce red blood cells. Folic acid has been shown to prevent physical problems in babies when taken by their mothers during pregnancy. Vitamin B-12 is found naturally in foods like eggs, meat, fish and milk products. Vitamin B-12 is found in green leafy vegetables and other foods, like legumes and citrus fruits (柑橘类水果).

Vitamin C is needed for strong bones and teeth. The body stores little vitamin C. So we must get it every day in foods such as citrus fruits, tomatoes and uncooked cabbage.

Vitamin D prevents the children’s bone disease rickets (佝偻病). Ultraviolet light from the sun changes a substance in the skin into vitamin D. Fish liver oil also contains vitamin D.

Vitamin K is needed for healthy blood. It thickens the blood around a cut to stop bleeding. It can also be found in pork products, liver and in vegetables like cabbage, kale and spinach (菠菜).

Vitamins are important to our health. A lack of required vitamins can lead to health problems.

【1】What is the main idea of the passage?

A. There are thirteen kinds of vitamins in total.

B. One can not live without enough vitamins.

C. Vitamins can carry out chemical changes within cells.

D. Enough vitamins are vital to keep healthy.

【2】 Women who wish to become mothers should take in ________.

A. vitamin A B. vitamin B-1

C. vitamin B-12 D. vitamin C

【3】What can change a substance in the skin into vitamin D?

A. Fish liver oil.

B. Ultraviolet light from the sun.

C. Fresh milk drunk by people.

D. Doing a certain amount of exercise.

4According to the passage, taking in enough vitamin C can ________.

A. make our eyesight better

Secret codes (密码)keep messages private。Banks, companies, and government agencies use secret codes in doing business, especially when information is sent by computer.

People have used secret codes for thousands of years. 【1】 Code breaking never lags(落后) far behind code making. The science of creating and reading coded messages is called cryptography.

There are three main types of cryptography. 【2】 For example, the first letters of My elephant eats too many eels Spell out the hidden message Meet me.

【3】 You might represent each letter with a number, For example, Lets number the letters of the alphabet, in order, from 1 to 26. If we substitute a number for each letter, the message Meet me would read 13 5 20 13 5.

A code uses symbols to replace words, phrases, or sentences. To read the message of a real code, you must have a code book. 【4】 For example bridge might stand for meet and out might stand for me. The message bridge out would actually mean Meet me. 【5】 However, it is also hard to keep a code book secret for long. So codes must be changed frequently.

A.It is very hard to break a code without the code book.

B.In any language, some letters are used more than others.

C.Only people who know the keyword can read the message.

D.As long as there have been codes, people have tried to break them.

E.You can hide a message by having the first letters of each word spell it out.

F.With a code book, you might write down words that would stand for other words.

G.Another way to hide a message is to use symbols to stand for specific letters of the alphabet.
