Every secnd, fur babies are brn in the wrld. Anther baby! Anther baby! Yu can nt even speak quickly enugh t keep up with the birth rate. The ppulatin is grwing larger and larger. S it ges n, hur after hur. In ne day, peple have t find fd fr ver 350,000 muths.
As a little girl was brn in a hspital in Philippines in 2011, the wrld’s ppulatin reached 7 billin. And the number is still increasing rapidly tday. S hw t cntrl the ppulatin is a big prblem fr us.

On Nvember 15, 2022, the United Natins（UN）reprted that the number f peple n Earth had grwn t eight billin（8,000,000,000）. That came just 11 years after the wrld reached seven billin peple. The wrld faces challenges ahead as the ppulatin cntinues t grw.
The wrld’s ppulatin—the number f peple n the planet—has grwn rapidly ver the last 200 years. In 1805, fr the first time ever, the Earth had a billin peple n it. It tk ver 100 years（in 1925）fr that number t duble（翻番）t tw billin. In less than 50 years, it had dubled again t fur billin. Nw, again in less than 50 years, the number has dubled nce mre t eight billin.
Hw fast lcal ppulatins are grwing depends a lt n where yu are in the wrld. Typically, as cuntries becme richer, their ppulatin grwth slws. In sme cuntries, like Japan, the number f peple is actually becming smaller. The greatest ppulatin grwth these days is fund in Asia and Africa. Currently, China, with a ppulatin f 1.4 billin, is the cuntry with the mst peple. That’s expected t change in the next year, when experts say India will pass China as the cuntry with the wrld’s largest ppulatin.
As the ppulatin grws, the wrld faces the increased challenges f hw t feed, educate, and meet the medical needs f everyne n the planet. This is nt easy because ppulatins are grwing mst quickly in prer cuntries. One reasn the wrld’s ppulatin is grwing is that, in general, peple are living lnger than they used t. In sme cuntries, this culd present a challenge, with mre and mre lder peple, but fewer yung peple t supprt them.
All in all, even thugh the wrld’s ppulatin cntinue t grw, ▲ . It’s impssible t say exactly what will happen in the future, but the rate f grwth is expected t keep slwing dwn. By 2050, the UN expects the Earth t have abut 9.7 billin peple. Experts say that by 2100, the planet’s ppulatin culd level ff at abut 10.4 billin peple.
26．Accrding t Paragraph 2, the wrld ppulatin grew mst rapidly frm ______ t ______.
A．1705;1805B．1805; 1925C．1925; 1974D．1974; 2022
27．Paragraph 4 is mainly abut _______ the ppulatin grwth.
A．the reasns frB．the advice t stp
C．the differences inD．the prblems caused by
28．Frm the passage, we can knw ________.
A．the wrld ppulatin reached 7 billin in 2020
B．the ppulatin in Japan is grwing fast these years
C．India will be the cuntry with the mst peple in 2023
D．ppulatins are grwing mre slwly in prer cuntries these days
29．Which f the fllwing can be put in ▲ in the last paragraph?
A．it will surely stp grwing sn
