【題目】中國(guó)的“新四大發(fā)明”：高鐵、支付寶、共享單車和網(wǎng)購(gòu)，改變了我們的生活，改變著整個(gè)世界。據(jù)此回答下列小題。

【1】我國(guó)高鐵線路東部比西部密集，是因?yàn)闁|部比西部 （ ）

①自然條件優(yōu)越 ②經(jīng)濟(jì)發(fā)達(dá) ③礦產(chǎn)豐富 ④人口稠密 ⑤草場(chǎng)廣闊

A. ①②③B. ③④⑤C. ①②④D. ①③⑤

【2】“新四大發(fā)明”說明我國(guó) （ ）

A. 交通運(yùn)輸便利B. 生物工程發(fā)展迅速

C. 新能源技術(shù)應(yīng)用廣泛D. 信息技術(shù)發(fā)展迅猛

【答案】

【1】C

【2】D

【解析】

隨著經(jīng)濟(jì)的發(fā)展和社會(huì)的進(jìn)步，人們的出行方式、購(gòu)物方式及其他生活方式都發(fā)生了巨大的變化，網(wǎng)購(gòu)已成為現(xiàn)代購(gòu)物的一種主流，實(shí)體店越來越少。

【1】高鐵是我國(guó)近些年來興趣的一種快速出行方式，高鐵是客運(yùn)方式，所以高鐵的分布主要考慮的是沿線的城市和人口，我國(guó)東部地區(qū)地勢(shì)平坦、經(jīng)濟(jì)發(fā)達(dá)，人口和城市密集，西部地區(qū)地形崎嶇，人口稀疏，所以高鐵的分布也呈現(xiàn)東部密集、西部稀疏的特點(diǎn)，故選C。

【2】我國(guó)新四大發(fā)明中的高鐵、支付寶、共享單車和網(wǎng)購(gòu)都反映了我國(guó)科技和信息技術(shù)發(fā)展迅速，人們之間聯(lián)系與交流的方式大大改變，故選D。

【題目】 Students in Kenya are returning for their third term. They begin their school year in January and it is broken up into three terms. In Kenya, in the past, students were not required to attend school an the education was not free, either.

I taugth math, English and physics at Chamasiri Secondary School whiel I was a teacher in Kenya. This school had four classrooms—one for each grade, Form 1, Form 2, Form 3 and Form 4. They are equivalent (對(duì)等) to our 9th ,10th ,11th, and 12th grade. Teachers traveled from classroom to classroom instead of the students going from room to room. The Form 1 class had 60 students, Form 2 had 45, Form 3 had 30, and Form 4 about 12 students. The class sizes became smaller as the grades continued on. Why did this happen? Many families were very poor and couldn’t afford the school fees(學(xué)費(fèi)).

Most countryside schools in Kenya did not have a lot of money. As a result, there were very few textbooks for the students to use. I had seven math texts for my Form 2 class and 14 for the Form 1 class. Anything the students needed to know was put up on the blackboard and the students copied it down into their noetbooks. The notebooks became the students’ textbooks.

Kenya students study ten different subject areas. Some of the students spend over an hour running home. They do chores at home and hopefully manage to find some time to study before it gets dark. Most familes do not have electricity and may not even have candles for their children to study by.

Luckily, Kenya education has been becoming better and better in the past few years. I’m sure it will have a good future.

【1】Which grade does Form 3 refer to (指的是) in ther writer’s country?

A. Grade 9.B. Grade 10.C. Grade 11.D. Grade 12.

【2】Why did the notebooks become the students’ textbooks?

A. The students did not pay the schools.

B. The schools couldn’t afford the textbooks.

C. The students preferred to use their notebooks.

D. The teachers asked the students to take notes.

【3】Why do some students run home from school?

A. They aren’t allowed to stay at school.

B. They don’t like studing in the school.

C. They hope to have more time to study.

D. They want to get candles in the stores.

【4】According to the passage, which of the following is NOT TRUE?

A. In Kenya, a school year has three terms.

B. The Form 1 class had the most students.

C. Each family has electricity in Kenya.

D. Kenya education has been improving.

科目：初中地理 來源： 題型：

【題目】 Are you short-sighted? If you are, your parents might have tried to do something to fix it, such as having you get an eye massage(按摩), take medicine or even get surgery(手術(shù)). People who offer these services or products often say that they can reduce or even cure short sight.

However, you will no longer see advertisements like this before long. The government has issued a notice to ban(禁止) businesses from using words like “recovery" or "short sight cure" in their advertisements.

The notice says that short sight cannot be completely cured with current medical technology. Therefore, these advertisements could mislead children and their parents.

Young people can prevent and control short sight by spending more time outside and less time in front of books or computers. People who have sight problems should first go to a hospital and let a doctor decide what to do.

More than 450 million Chinese have suffered from short sight since June 2018. Short sight rates are around 30 percent for primary school students, 60 percent for junior high school students and 80 percent for senior high school students. This is likely because students spend a lot of time reading books and using electronic devices.

To reduce short sight among young people, the government made a new plan last August. The plan is designed to limit the amount of time children spend playing video games, as well as limit the production of new video games.

【1】Some people say that they can cure short sight to _________.

A. show off their high-leveled skillsB. sell more products and services

C. share their medical technologyD. prove that eye massages are useful

【2】Advertisements with the word "__________“ will be banned by the government.

A. recoveryB. eyesightC. short sightD. surgery

【3】If you have a sight problem, you should ___________ first.

A. get surgeryB. get an eye massage

C. take some medicineD. ask a doctor for advice

【4】According to this passage, which group has the highest short sight rate?

A. Primary school students.B. Junior high school students,

C. Senior high school students.D. College students.

【5】From the last two paragraphs, we can know that _________.

A. students should be stopped from using mobile phones

B. students in lower grades are more likely to get short sight

C. production of new video games will be limited

D. a law was made to protect the eyesight of people
